2019年6月大學英語四級閱讀理解訓練：跡運前宇宙
A scientist once said: 「I have concluded that the earth is being visited by intelligently controlled vehicles from outer space.」
If we take this as a reasonable explanation for UFOs (unidentified flying objects), questions immediately come up.
姿清「Why don』t they get in touch with us, then? Why don』t they land right on the White House lawn and declare themselves?」 people asked.
悄租In reply, scientists say that, while this may be what we want, it may not necessarily be what they want.
「The most likely explanation, it seems to me,」 said Dr. Mead, 「is that they are simply watching what we are up to -- that responsible society outside our solar system is keeping an eye on us to see that we don』t set in motion a chain reaction that might have unexpected effects for outside our solar system.」
Opinions from other scientists might go like this: 「Why should they want to get in touch with us? We may feel we』re more important than we really are! They may want to observe us only and not interfere with the development of our civilization. They may not care if we see them but they also may not care to say 『hello』.」
①Some scientists have also suggested that Earth is a kind of zoo or wildlife reserve. ②Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them, so perhaps Earth was set aside ages ago for the same purpose.
①Are we being observed by intelligent beings from other civilizations in the universe? ②Are they watching our progress in space travel? ③Do we live in a gigantic 「zoo」 observed by our 「keepers,」 but having no communication with them?
①Never before in our history have we had to confront ideas like these. ②The simple fact is that we, who have always regarded ourselves as supreme in the universe, may not be so. ③Now we have to recognize that, among the stars in the heavens, there may very well be worlds inhabited by beings who are to us as we are to ants.
一、詞彙
1.conclude v. 作結論，推斷
2.vehicle n. 交通工具
3.be up to sth= be doing sth正在做
4.keep an eye on sb監視某人
5.set in motion使某物運轉
6.reserve n. 貯存，預備舍
7.set aside 保留
8.supreme a. 最高的
9.inhabit v. 居住於，占據
二、長難句
1. The most likely explanation, it seems to me,」 said Dr. Mead, 「is that they are simply watching what we are up to -- that responsible society outside our solar system is keeping an eye on us to see that we don』t set in motion a chain reaction that might have unexpected effects for outside our solar system.
該句的賓語由直接引語構成。該直接引語的主幹為The most likely explanation is that …，破折號的部分對that引導的表語從句進行解釋說明。該部分的主幹為responsible society … is keeping an eye on us，不定式結構to see that …做目的狀語。其中第一個that引導的從句做see的賓語，第二個that引導的從句做後置定語，修飾先行詞chain reaction。
翻譯：米德博士稱「在我看來，最可能的解釋是他們只不過是看看我們在做什麼——我們太陽系之外有責任心的社會正留意著我們，以確保我們不會觸發某種連鎖反應，從而給太陽系之外的星系造成意想不到的影響。」
2. Just as we set aside wilderness areas and wildlife reserves to allow animals and growing things to develop naturally while we observe them, so perhaps Earth was set aside ages ago for the same purpose.
該句為主從復合句，just as引導方式狀語從句，其中還嵌套了while引導的時間狀語從句。主句部分的主幹為perhaps Earth was set aside。
翻譯：就像我們劃出野生動物活動區和保護區以便我們可以在自然狀態觀察動植物的生長情況一樣，或許地球就是很早以前為達到相同的目的而被劃出的保護區。
3. Now we have to recognize that, among the stars in the heavens, there may very well be worlds inhabited by beings who are to us as we are to ants.
該句的主幹為we have to recognize that …，that引導的從句做賓語。該從句的主幹為there may very well be worlds，過去分詞短語inhabited by beings …做後置定語，修飾名詞worlds，who引導的定語從句也做後置定語，修飾beings。
翻譯：現在我們必須認識到在茫茫星海中，也許就有這樣的星體，那上面居住的生物看待我們就如同我們看待螞蟻一樣。
三、文章結構分析
本文是一篇探討外星生物是否存的時文。
第一至三段：通過一位科學家的話引出爭論的焦點：外星生物是否存在?
第四至八段：羅列了科學家們對此問題而產生的四種猜測—不願同人類接觸、在暗中留意人類的行動、只出於觀察目的而不想同人類接觸、地球是外星人劃立的「動物」保護區。
第九段：總結全文，肯定外星生物的存在，並提醒人們宇宙中存在著更強大生物的可能性。
四、試題具體分析
11. People who ask the question 「Why don』t they get in touch with us... and declare themselves?」 think that ________.11. 提出「那麼他們為什麼不和我們聯系呢?為什麼他們不正好降落到白宮的草坪上然後自我介紹一下呢?」這些問題的人認為________.
[A] there are no such things as UFOs[A] 不明飛行物這種東西是不存在的
[B] UFOs are visitors from solar system[B] 不明飛行物是來自太陽系的探訪者
[C] there』s no reason for UFOs sooner or later[C] 對於不明飛行物的說法遲早會理屈詞窮的
[D] we are bound to see UFOs sooner or later[D] 人類遲早會看見不明飛行物的
[分析]本題考查的知識點是：推理引申。
根據第一、二段可知，題干中的問題是「如果將來自外太空的智能飛船正在造訪地球作為對不明飛行物的合理解釋」就會出現的問題。第四到七段引用科學家的話對這一問題給予了回復：對為什麼人類同外星人之間沒有聯系進行了推測。可見，問這些問題的人並不相信外星生物或不明飛行物是存在的，而科學家的推測卻在證明它們可能是存在的。故[A]選項正確。
[B]選項是根據UFOs和solar system編造的干擾項，且[B]選項本身表達亦不正確。文中指出如果外星人是存在的，那他們一定存在於太陽系之外的某個星系之中。[C]選項錯在no reasons。文章第四到七段給出針對這些問題的解答，所以並非是理屈詞窮。[D]選項反向干擾，從上面的分析可知提出問題的人是不相信UFOs是存在的，所以他們也不會認為遲早會見到不明飛行物。
12. According to Dr. Mead, the attitude of beings from outer space toward us is one of ________.12.米德博士認為來自外太空的生物對人類的看法會是_______。
[A] unfriendliness[A] 不友善的
[B] suspicion[B] 猜疑的
[C] superiority[C] 盛氣凌人的
[D] hostility[D] 敵意的
[分析]本題考查的知識點是：推理引申。
根據題中人物關鍵詞Dr. Mead定位到文章第五段。針對一些人提出的外星人為何不同人類接觸的問題，米德博士認為最可能的解釋就是他們只是負責留意我們，確保我們的行動不會觸發能夠危害到他們的連鎖反應。由此可知，米德博士的觀點是外星人對人類的態度應該是猜疑的，故[B]選項正確。
[A]、[C]選項都是其他猜測認為來外星生物會對人類所持的態度。[D]選項從文中無從推知。
13. The tone of the writer is that of ________.13. 作者的語氣是________。
[A] doubt[A] 懷疑的
[B] warning[B] 警告的
[C] indifference[C] 冷漠的
[D] criticism[D] 批判的
[分析]本題考查的知識點是：作者態度。
文章第八段是作者觀點的闡述。第八段第二句指出人類從未有過外星生物是否存在的想法正是人類自身的盲目優越感所致。作者認為也許正是這種盲目自大，使我們否定了外星生物的存在，但是外星生物一定是存在於茫茫宇宙的某個星體上，他們看待我們就如同我們看待螞蟻一般。可見本文作者所持的是批判的態度，故[D]選項正確。
[A]選項反向干擾。第八段第三句話明確指出，我們必須認識到茫茫星海中也許真的有外星生物的存在。從文中無法得出作者對否定外星人存在的人所給的警示之語，故排除[B]選項。第八段中always, supreme, have to, who are to us as we are to ants等表明了作者並不是漠然的，故[C]選項錯誤。
五、全文翻譯
一位科學家曾說過「我斷定來自外太空的智能飛船正在造訪地球。」
如果我們將其作為對不明飛行物的合理解釋，那麼問題馬上就來了。
人們會問：「那麼他們為什麼不和我們聯系呢?為什麼他們不正好降落到白宮的草坪上然後自我介紹一下呢?」
對於這些問題，科學家們的回答是：雖然這也許是我們想要的，但這也許並不是他們想要的啊。
米德博士稱「在我看來，最可能的解釋是他們只不過是看看我們在做什麼——我們太陽系之外有責任心的社會正留意著我們，以確保我們不會觸發某種連鎖反應，從而給太陽系之外的星系造成意想不到的影響。」
其他科學家的觀點是這樣的：「他們為什麼要聯系我們?我們也許把自己想的過於重要了!他們也許就是想觀察我們而不想介入人類文明的發展。他們也許並不關心我們是否看到了他們，也不關心是否打個招呼。」
還有一些科學家認為，地球就是一個動物園或是野生動物保護區。就像我們劃出野生動物活動區和保護區以便我們可以在自然狀態觀察動植物的生長情況一樣，或許地球就是很早以前為達到相同的目的而被劃出的保護區。
宇宙中其他文明的智能生物正在觀察我們么?他們正留意我們在太空航行上的進展么?我們是生活在一個只能被「飼養員」觀察卻無法與其溝通的巨型「動物園」里么?
在人類的歷史上，我們從未遇到過類似的想法。真相很簡單，那就是我們總認為在整個宇宙中我們是至高無上的，可事實也許並非如此。現在我們必須認識到在茫茫星海中，也許就有這樣的星體，那上面居住的生物看待我們就如同我們看待螞蟻一樣。
2019年6月大學英語四級閱讀理解訓練：汽車
①The use of the motor is becoming more and more widespread in the twentieth century; as an increasing number of countries develop both technically and economically, so a larger proportion of the world』s population is able to buy and use a car. ②Possessing a car gives a much greater degree of mobility, enabling the driver to move around freely. ③The owner of a car is no longer forced to rely on public transport and is, therefore, not compelled to work locally. ④He can choose from different jobs and probably changes his work more frequently as he is not restricted to a choice within a small radius. ⑤Travelling to work by car is also more comfortable than having to use public transport; the driver can adjust the heating in winter and the air conditioning in the summer to suit his own needs and preference. ⑥There is no irritation caused by waiting for trains, buses or underground trains, standing in long patient queues, or sitting on windy platforms, for as long as half an hour sometimes. ⑦With the building of good, fast motorways long distances can be covered rapidly and pleasantly. ⑧For the first time in this century also, many people are now able to enjoy their leisure time to the full by making trips to the country or seaside at the weekends, instead of being confined to their immediate neighbourhood. ⑨This feeling of independence, and the freedom to go where you please, is perhaps the greatest advantage of the car.
①When considering the drawbacks, perhaps pollution is of prime importance. ②As more and more cars are proced and used, so the emission from their exhaust-pipes contains an ever larger volume of poisonous gas. ③Some of the contents of this gas, such as lead, not only pollute the atmosphere but cause actual harm to the health of people. ④Many of the minor illnesses of modern instrial society, headaches, tiredness, and stomach upsets are thought to arise from breathing polluted air; doctors』 surgeries are full of people suffering from illnesses caused by pollution. ⑤It is also becoming increasingly difficult to deal with the problem of traffic in towns; most of the important cities of the world suffer from traffic congestion. ⑥In fact any advantage gained in comfort is often cancelled out in city driving by the frustration caused by traffic jams: endless queues of cars crawling one after another through all the main streets. ⑦As an increasing number of traffic regulation schemes are devised, the poor bewildered driver finds himself diverted and forced into one-way systems which cause even greater delays than the traffic jams they are supposed to prevent. ⑧The mounting cost of petrol and the increased license fees and road tax all add to the driver』s worries. ⑨In fact, he must sometimes wonder if the motor car is such a blessing and not just a menace.
一、詞彙
1.Mobility n. 可動性,變動性
2.Radius n. 半徑
3.Preference n. 偏愛
4.irritation n. 煩惱
5.queue n. 長隊
6.cover v. 行走(距離)
7.confine v. 限制
8.prime a. 首要的,最好的
9.bewildered a. 困惑的
10.divert v. 轉移
11.blessing n. 祝福
12.menace n. 威脅
二、長難句
As an increasing number of traffic regulation schemes are devised, the poor bewildered driver finds himself diverted and forced into one-way systems which cause even greater delays than the traffic jams they are supposed to prevent.
該句為主從復合句。句首為as引導的時間狀語從句，主幹為the poor bewildered driver finds himself diverted and forced …，其中包含「find oneself +過去分詞」結構，意為「發現自己(處於某狀態)」。Which引導的定語從句做後置定語，修飾先行詞one-way systems。
翻譯：當越來越多的交通管理方案出台時，暈頭轉向的司機發現可憐的自己被迫轉進了一條單行道，這樣耽誤的時間超過了他們所避免的交通擁堵時間。
三、文章結構分析
文章主要探討了汽車廣泛使用的利弊問題。
第一段：指出了汽車廣泛使用的原因並論述汽車給人類帶來的好處：靈活、舒適、快捷、自主。
第二段：主要論述了由於汽車的廣泛使用給人類帶來的困擾：大氣污染、健康威脅、交通堵塞、費用負擔。
四、試題具體分析
14. More and more people can afford to buy and use cars because ________.14. 越來越多的人能夠購買並使用汽車是因為________。
[A] an increasing number of cars are being proced[A] 生產的汽車越來越多
[B] the cost of cars is getting cheaper with the development of technology[B] 隨著技術的進步，汽車的成本也越來越低了
[C] lots of countries have become more developed[C] 許多國家都步入了發達國家之列
[D] the use of cars has proved to be more economical[D] 已經證實使用汽車是較經濟的
[分析]本題考查的知識點是：因果細節。
文章第一段①句指出，因為越來越多的國家在技術和經濟領域都取得了進步，所以世界上大部分人都能購買並使用汽車了。[C]選項正是對此句話的概括，故正確。
[A]選項張冠李戴。將「汽車的尾氣管里排出了更多含有有毒物質的廢氣的原因，即人們生產的汽車越來越多了」，當成是「越來越來人購買並使用汽車的原因」。[B]選項無中生有，是利用原文詞彙develop technically和the cost 編造的干擾項。第二段⑧句指出，飆升的油價和日益上漲的駕駛執照費和養路費使駕車人變得更加憂心忡忡。可見，使用汽車並不會為其所有者節省錢，故排除[D]選項。
15. The advantages of having a car are best experienced in the driver』s ________.15. 擁有汽車最大的好處是駕車人能夠體驗________。
[A] freedom in choosing his job[A] 選擇工作的自由
[B] comfort ring the travels[B] 旅行中舒適的感覺
[C] enjoyment of his leisure time[C] 閑暇時光的享受
[D] feeling of self-reliance[D] 自立的感覺
[分析]本題考查的知識點是：具體細節。
第一段末句明確指出，自主的感覺以及去任何想去的地方的那種自由或許是汽車最大的優點了，故[D]選項正確。
[A]、[B]、[C]選項都是文中談到的擁有汽車的好處，但並非最大優點，故排除。
16. What is considered by the writer as the greatest menace to the people caused by the widespread use of motor cars?16. 作者認為汽車的廣泛使用對人們造成的最大威脅是什麼?
[A] air pollution[A]空氣污染
[B] traffic jams[B]交通堵塞
[C] fatal diseases[C]致命疾病
[D] high cost[D]高額成本
[分析]本題考查的知識點是：具體細節。
文章第二段①句即明確指出，對於汽車使用的最大弊端可能就是汽車造成的污染問題。故[A]選項正確。
[B]、[D]選項雖然都是汽車使用對人們生活和健康的威脅，但並不是最大的威脅，故排除。[C]選項本身即錯誤。第二段第四句指出，現代工業社會中許多小病都是由於吸入被汽車尾氣污染了的空氣而引起的。可知，汽車的使用並不會引發致命的疾病。
五、全文翻譯
二十世紀，汽車的用途變得越來越廣泛了，因為越來越多的國家在技術和經濟領域都取得了進步，所以世界上大部分人都能購買並使用汽車了。擁有一輛汽車就相當於具有更大的靈活性，開車的人可以自由活動。有汽車的人不必再依靠公共交通工具，因此也不必在工作所在地居住了。他可以選擇不同的工作，也可能更頻繁地跳槽，他不必在離家很近的范圍內選擇工作了。同乘坐公共汽車相比，開車上班也更加舒適些，人們可以按自己的需要和喜好隨著季節來調節車內供暖和空調系統。有時人們要花半個小時站在長長的隊伍里或坐在當風的站台內等火車、公交或地鐵，由這種情況導致的惱怒也會隨著汽車的使用而消失。隨著寬敞快捷的高速公路的修建，長途旅行變得快捷且愉快了。許多人能夠在周末的時候開車去鄉村或海邊，好好地享受他們的閑暇時光，而不用限制在住家附近的地方活動，這在本世紀也屬首次了。自主的感覺以及去任何想去的地方的那種自由或許是汽車最大的優點了。
考慮到不好的方面，汽車造成的污染或許是其最大的缺點。因為人們生產和使用的汽車越來越多，所以汽車的尾氣管里會排出更多含有有毒物質的廢氣。這種氣體中一些成分的，例如鉛，不僅污染了大氣還對人們健康造成了實際傷害。人們認為現代工業社會中許多小病，例如，頭痛、疲勞以及胃不適，都是由於吸入污濁的空氣而引起的，醫生的診室裡面充滿了受其累的病患。處理城市裡交通問題也變得越來越棘手了，世界上大多數重要城市都飽受交通堵塞之苦。事實上，在城市中駕車而行，從這種舒適中獲取的任何好處都被由交通堵塞造成的沮喪感給抵消了：一眼望不到邊際的汽車長龍，一輛跟著一輛慢慢爬過每一條主街道。當越來越多的交通管理方案出台時，暈頭轉向的司機發現可憐的自己被迫轉進了一條單行道，這樣耽誤的時間超過了他們所避免的交通擁堵時間。飆升的油價和日益上漲的駕駛執照費和養路費使駕車人變得更憂心忡忡。事實上，他肯定有時候會想弄清楚汽車真的只會帶來幸福而不會對我們造成威脅么。
2. 關於18年6月的英語四級仔細閱讀答案
大學英語四級考試真題（卷二）之仔細閱讀
【篇章分析】
本篇文章整體閱讀難度並不大，主要講的是關於居住在綠色生態空間的人們要比居住在市區的人們擁有長期的積極的幸福影響。文章後的五道題目以事實細節考查為主，題干定位信息明確，做題難度在中等偏下水平。
【參考答案】
46 B Add to their sustained happiness.
47 A Earn more money.
48 C How long its positive effect lasts.
49 D Their communication with others improved.
50 A Find financial support.
【答案解析】
46. 根據題干中的定位名詞study和green spaces迴文快速定位到文章中的第一段，根據第一段的信息可得出UK
researchers found moving to a green space had a sustained positive
effect（英國研究者發現搬到綠色小區可以帶來持久的積極影響）。以及「people living in greener urban areas
were displaying fewer signs of depression or
anxiety（生活在綠色小區的人們較少表現出抑鬱或焦慮的情緒）」這兩處信息可以確定本題的正確選項是B （Add to their
sustained happiness）。
47. 本題根據題干定位詞Dr. White 及usually do定位到本篇文章中的第一段"There could be a
number of reasons,」 he said, 「for example, people do many things to make
themselves happier: they strive for promotion or pay rises, or they get
married.處，根據本句信息，可推出人們通常讓自己快樂的事是掙更多的錢，因此本題的正確選項為A（Earn more money.）。
48. 由第一段可知「升值、加薪、中彩票只會給人們帶來短期的快樂，這種快樂在過了六個月到一年後就會消失」，第二段首句「Dr. White
said his team wanted to see whether living in greener urban areas had a
lasting positive effect on people's sense of well-being or whether the
effect also disappeared after a period of time.」進一步承接第一段說明Dr.
White的研究目的是要知道居住在綠色環境中給人帶來的積極影響可以持續多久。故本題正確選項為C選項（How long its positive
effect lasts.）。
49. 根據題干信息可以將本題定位至第三段，在最後一句話中，「He observed that people living in
green spaces were less stressed, and less stressed people made more
sensible decisions and communicated better.」由最後的communicate better
可以得出本題的正確選項為D （Their communication with others improved.）。
50. 根據本題題干給出的信息，根據定位詞Dr. White
和government，可定位至最後一段，提到我們需要資金來建立一個高質量的綠色社區，從最後一段的最後一句話「what we really
need at a policy level is to decide where the money is going to come
from to help support good quality local green spaces.」可得出本題的正確選項為A（Find
financial support.）。

提高四級閱讀理解成績的方法
1、了解文章main idea(主要意思)
做英語閱讀理解就好像做語文閱讀理解時一樣，要知道這篇文章的主旨或者說是中心思想，對文章所講的主旨內容和它的中心思想做到心裡有數。達到一種高度——只要一做英語閱讀理解題，腦子里就要條件反射的蹦出main idea，然後再去閱讀問題和文章。
2、先看問題，再粗讀文章
帶著尋找main idea的思想，先去看一遍問題，把問題中的關鍵詞圈出來，然後再去粗略的讀一遍文章。在讀的時候，不用做到每個單詞都看懂，每句話都能翻譯出來。只要對文章大致上有一個了解就夠了，這樣文章的main idea也就出來了。
要注意的是，在讀到覺得跟所問問題有關聯的句子的時候，可以先用筆把句子勾出來，在上邊標記上有關聯的問題的題號，然後接著往下讀。
3、精讀問題和所標記的句子
讀完通篇的同時，也把跟問題有關的的句子畫出來了，這個時候再去精讀標記的句子，仔細研究問題和跟問題有關的句子，琢磨其意思，盡量做到胸有成竹，然後再回答每一個問題。
4. 12月英語四級閱讀解析：矽谷之所以為矽谷
2015年12月英語四級閱讀解析：矽谷之所以為矽谷
2015年12月19日全國大學英語四級考試已結束，本次考試為多題多卷，以下是2015年12月英語四級閱讀解析：
首先，我們通過文章可以了解到，該篇閱讀的主要內容與之前四級考試所關注的閱讀文章的`主題類似，也是關於科技話題的。在這篇文章中，作者主要闡釋了矽谷之所以成為矽谷的不可替代和復制性。主要原因為：(1)rich people;(2)nerds。是這兩個原因成就了矽谷。文章中，作者拿矽谷和邁阿密、康奈爾及波士頓進行了對比，總結得出：其他的三個城市之所以不能成為矽谷第二的原因。
接下來，我們就第一篇閱讀的答案選項和各位同學一起分享下：
第56題，what do we learn about Silicon Valley from the passage? 這道題目直接可以定位到文中的第一段中：Could you please reproce Silicon Valley elsewhere， or is there something unique about it? 然後在下文中，作者又進一步的指出了矽谷不可代替性的原因。所以答案選項為：Its success is hard to anywhere else
第57題，what makes Miami unfit to proce a Silicon Valley? 這道題目可以定位到原文中的第五段，文中直接指出：it has few nerds。 It is not the kind of place nerds like。 這樣就可以直接選出：Lack of the right kind of talents。
第58題，In what way is Carnegie-Mellon different from Stanford， Berkeley and MIT? 根據題干信息，我們可以直接定位到文中的第六和七段：the weather is terrible， particular in winter， and there ‘s no interesting old city to make up for it， as there is in Boston。 所以選項很明了：Its location is not as attractive to rich people
第59題，what does the author imply about Boston? 這道題的關鍵就在於the weather is terrible， particular in winter， and there ‘s no interesting old city to make up for it， as there is in Boston中的as一詞，這里as 後引導的是 there is no interesting old city to make up for it in Boston。所以正確選項為：what does the author59.It is not likely to attract lots of investors and nerds
say about startup investors? 這道題在文中定位到最後一段：startup investors are a distinct 。。。。。。as well as money。 這樣該題正確選項為：They can do more than providing money
希望以上答案能夠給各位考生提供參考幫助，且預祝各位考生考試成功。
;5. 2019年6月大學英語四級閱讀理解訓練三篇
2019年6月大學英語四級閱配殲讀理解培猛沖訓練：夢
Of all the components of a good night's sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by thelate 1970s, neurologists had switched to thinking of them as just "mental noise"-the random byprocts of the neural repair work that goes on ring sleep. Now researchers suspect that dreams are part of the mind's emotional thermostat, regulating moods while the brain is "off line." And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. "It's your dream," says Rosalind Cartwright, chair of psychologyat Chicago's Medical Center, "if you don't like it, change it."
he link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated ring the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events-until, it appears, we begin to dream.
知脊And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualizehow you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings.Sleep-or rather dream-on it and you'll feel better in the morning.
練習題：
Choose correct answers to the question:
1.By saying that 「dreams are part of the mind's emotional thermostat," (Lines 4-5, Para. 1) the researchers mean that _______.
A.we can think logically in the dreams too
B.dreams can be brought under conscious control
C.dreams represent our unconscious desires and fears
D.dreams can help us keep our mood comparatively stable
2.What did Cartwright find in her clinic?
A.Most bad dreams were followed by happier ones.
B.Divorced couples usually have more bad dreams.
C.One』s dreaming process is related to his emotion.
D.People having negative feelings dream more often.
3.Cartwright believed with much practice，we can learn to _____.
A.control what dreams to dream
B.sleep well without any dreams
C.wake up in time to stop the bad dreams
D.identify what is upsetting about the dreams
4.The author points out that a person who has constant bad dreams should ______
A.learn to control his dreams
B.consult a doctor
C.sleep and dream on it
D.get rid of anxiety first
5.The author most probably thinks that controlling dreams is ______.
A.a good practice
B.a new discovery
C.helpful for everyone
D.not essential for everyone
參考答案及解析
1.[D] 詞義理解題。在第1段第4句中，逗號後面的regulating moods是對emotional thermostat的功能進行解釋說明，因此可以推斷出選項D正確。
2.[C] 事實細節題。最具干擾的是選項A，因為其陳述與第2段第2句的陳述有點相似,但是，此長句說的是大多數人上半夜做噩夢，之後都會做好夢，而不是像選項A中所說大多數噩夢之後是好夢。而且，根據本段第1 句，很明顯，選項C是這一句的近義替換。
3 [C] 推理判斷題。本題考査對代詞的理解。在第3段的最後一句中，代詞it應指上文說到的控制噩夢，及時醒來等做法，因此只有選項C涉及了其中一個做法。選項A太泛了，選項B和D在文中並無提及。
4.[B] 事實細節題。本題考查根據構詞法猜測詞義的能力。解題關鍵是推斷最後一段第3句中therapist的意義，在考綱詞彙表中，therapy是「治療」的意思，因此，therapist應該是專門負責某種治療的醫生，由此可見，選項B是對原文seek help from a therapist的近義替換。
5.[D] 觀點態度題。根據最後一句可以推斷作者認為如無必要，夢還是不要控制的好。做夢會讓你早上感覺舒服一些，因此本題應選D。
2019年6月大學英語四級閱讀理解訓練：機器人跳舞
The dancers stand motionless at their position and the room grows silent. But as the music starts, they began to move, bending, turning and waving their fans gracefully as they perform. a traditional Japanese dance. Yoshihiro Kuroki watches in silence, occasionally making notes. But as the dance ends, he beams with happiness. The performance has been flawless.
There have been many performances of traditional Japanese dances over the centuries, but this one is unique,because it is performed not by human dancers but by robots. And the performance takes place not in a dance studio but in a laboratory of Sony Corp.'s Entertainment Robot Co. in Shinagawa, Japan, where Kuroki isgeneral manager. He is the mastermind behind a series of even more capable humanoid entertainment robots,starting with the Sony Dream Robot, or SDR, in 1997, up to the current QRIO in 2003.
These delightful machines are only 58 cm tall, about the size of a newborn infant, weigh about 7 kg, and move with 38 degrees of freedom, each with its own servomotor(輔助馬達).
QRIO's predecessor, the SDR4X, announced in 2002, can walk, dance, sing, speak, recognize faces, and understand continuous speech. Each robot has two charge-coupled-device cameras to detect color and position andcan locate a colored ball, move toward it, and kick it into a goal. It also has contact sensors in severaljoints to avoid pinching real human fingers. Seeing the robot perform, it is difficult to remember that there is no sentience(知覺)behind those glass eyes.

參考答案及解析
1.[A] 主旨大意題。標題需要既全面又突出地概括文章的主題。本文先是描述「舞蹈演員」，然後揭曉這是些「機器人」(第2段第1句)，接著對Sony公司的一些機器人產品進行詳細介紹。選項A比較全面地概括了文章內容。選項B、D只是涉及細節，不能全面地概括本文的內容。而C又過於籠統，不具有針對性。
2.[C] 事實細節題。選項C符合第2段最後一句「He is the mastermind behind a series of... robots...」。仔細閱讀有關的細節信息會發現,第1段第3句可幫助否定選項A。第1段最後兩句可幫助否定選項B。另外，根據第2段倒數第2句可否定選項D。
3.[D] 事實細節題。全文分四段，分別討論機器人三方面的特點：第1段和第2段描述機器人舞蹈演員栩栩如生的表演，即選項A;第3段描寫它們的外表，即選項B;第4段介紹它們巧妙的設計，即選項C;只有選項D是沒有提到的，故為答案。
4.[A] 推理判斷題。該句中的分詞結構「starting with...」表明the Sony Dream Robot是第一個人形娛樂機器人，因此選項A正確。文章在最後一段的第1句提到兩種能說話、跳舞的機器人，但沒有提到SDR是否和它們一樣，由此可否定選項B。在第3段討論機器人大小的時候也沒有提到SDR體型最大，因此選項C不正確。選項D在文中沒有討論到。
5.[B] 事實細節題。該句中「two…cameras to...」的結構表明這兩個攝像頭可以用於定位，所以選項B正確。選項A在該句中也有提到，但它只是攝像機的工作機制，而不是用於定位的裝置。選項C在下一句提到，但與題干提到的定位功能無關。選項D在文中並未提及。
2019年6月大學英語四級閱讀理解訓練：決定嬰兒性別
Henry III didn't know much about biology. He went through six wives back in the 1500s, looking for one whocould bear him a son. Scientists now know that it's the father's sperm, not the mother's egg, which determines whether a baby is a boy or a girl. And last week researchers at the Genetics and IVF Institute, a private fertility(生育能力)center in Virginia, announced a new technique that will allow parents to choose the sex of their baby-to-be, before it has even been conceived. The scientist used a tiny laser detector to measure the DNA in millions of sperm cells as they pass single file through a narrow tube, like cattle being herded through a corral(牲口欄). In a study published last week, "girl sperm," which has more DNA—the genetic material— in each cell, was collected, while "boy sperm" was discarded. And when purified girl sperm was used to impregnate(使受孕)a group of mothers, 15 of 17 resulting babies turned out to be girls.
The researchers say that "sex selection" can also double a mother's chance of having a son and can be usedto avoid genetic diseases that affect only one gender, such as hemophilia(血友病). But some experts, like New York University fertility specialist Dr. Jamie Grifo, worry that sex selection could lead to a kind ofin uteri(子宮)discrimination, especially in cultures where sons are considered superior to daughters. "It's valuing one gender' over another," Grifo says. "I don't think that's something we should be doing." So far, patients at the institute have been asking for both boys and girls, in order to "balance" their families. And some ethics experts say that's fine, as long as parents are just looking for a little gender variety. "If you have three boys, and you want a girl," says University of Texas reproctive-law professor John Robertson, "that's not gender bias at all."
練習題：
Choose correct answers to the question:
1.The DNA in the sperm cells can be measured ______.
A.in the same way how the cattle are herded
B.when they pass through a tube one behind the other
C.after they pass through a laser tube
D.when they are scanned by a laser detector all at a time
2.The gender of the baby is decided by ______.
A.the father's DNA
B.the mother's DNA
C.the father's sperm
D.the mother's egg
3.According to this passage, the practice of "sex selection" ______.
A.can help to prevent all genetic problems
B.is totally unacceptable to ethics experts
C.was already realized five hundred years ago
D.will benefit families with certain inheritable diseases
4.Girl sperm was preferred to boy sperm in the research most probably because____
A.girl sperm contains more genetic material
B.more mother want to have girl babies
C.girl sperm is healthier and more active
D.girl sperm is more easily purified
5.It can be concluded from the passage that author』s toward」sex selection」is____
A.negative
B.positive
C.neutral
D.favorable
參考答案及解析
1.[B] 推理判斷題。解答本題的關鍵在於推斷single file的意思。該句把精子通過試管的情形與牛群被趕入牲口圈的情形作對比，結合single一詞本身的意思，可以推斷single file是「一個接一個」的意思，只有選項B能表達這個意思，由此也可否定選項D。選項A最具干擾性，原句是把精子通過試管的情形比作牛群被趕人牲口圈的情形，而選項A說的是測定精子內DNA的方法與放牧的方法相同，顯然選項A只是引用了原文的某些詞語，但表達的意思與原文卻截然不同。
2.[C] 事實細節題。第1段第3句which引導的非限制性定語從句修飾的是the father's sperm，而不是插入語the mother』s egg,因此選項C正確。
3.[D] 推理判斷題。第2段第1句中的genetic暗示有些疾病是遺傳的，即如選項D所述。第2段第1句同時表明選項A的說法是不全面的。選項B與第2段最後兩句正好相反。第1段前兩句說明選項C是錯誤的。
4.[A] 事實細節題。第1段倒數第2句中的由which引導的定語從句表明選項A的敘述正確。
5.[C] 觀點態度題。文章第2段中作者給出了一些反對者和贊成者的觀點，但是沒有加以評論，可以看出作者的態度是中立的，故選項C正確。
6. 大學四級考試閱讀訓練題及答案
英語閱讀是英語四級考試中的重要考察能力之一，只有做好閱讀部分的題目才能提高四級考試的成績。下面我為大家帶來大學四級考試閱讀訓練題，供考生備考練習。
大學四級考試閱讀訓練題***一***
According to the dictionary definition of 「create」, ordinary people are creative every day. To create means 「to bring into being, to cause to exist」—something each of us does daily.
We are creative whenever we look at or think about something in a new way. First this involves an awareness of our surroundings. It means using all of our sese to bee aware of our world. This may be as simple as being aware of color and texture, as well as taste, when we plan a meal. Above all, it is the ability to notice things that others might miss.
A second part of creativity is an ability to see relationships among things. I f we believe the expression, 「There is nothing new under the sun,」 the creativ ity is remaking or rebining the old in new ways. For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new bination of camera lenses and filters to cr eate an unusual photograph.
A third part of creativity is the courage and drive to make use of our new ide as, to apply them to achieve some new results. To think up a new concept is one thing; to put the idea to work is another.
These three parts of creativity are involved in all the great works of genius, but they are also involved in many of our day to day activities.
26.Which of the following activities is NOT a creative one according to t he passage?
A.To prepare a meal.
B.To arrange the furniture in a peculiar way.
C.To buy some books from a bookstore.
D.To 「write」 a letter with the puter.
27.The author holds that ____.
A.creativity is of highly demand
B.creativity is connected with a deep insight to some extent
C.creativity is to create something new and concrete
D.to practise and practise is the only way to cultivate one』s creativity
28.「There is nothing new under the sun.」 ***Par.3*** really implies that ____.
A.we can seldom create new things B.a new thing is only a tale
C.a new thing can only be created at the basis of original things D.we can scarcely see really new things in the world
29.What does the author think about the relationship between a new though t and its being put into practice?
A.It』s more difficult to create a new thought than to apply it in practice.
B.To find a new thought will definitely lead to the proction of a new thing.
C.One may e up with a new thought, but can not put it into practice.
D.A man with an excellent ability of practice can easily bee an inventor.
30.The best title for this passage is ____.
A.How to Cultivate One』s Creativity B.What is Creativity
C.The Importance of Creativity D.Creativity—a Not Farway Thing
大學四級考試閱讀訓練題答案
26.答案C。本題可用排除法。根據第一段可知創造力的含 義是「使事物產生」，「致使事物存在」。而它三個方面的表現可參考「短文大意」，據此，C為正確答案。
27.答案B。此題的解答需要在理解文章大意及細節基礎上進行。選項B意為「創造力在一定程度上取決於非凡的洞察力。」根據最後一段，可知這是一種「天賦」，故正確。這樣就可確定B為正確答案。
28.答案C。此題可在正確理解句子含義的基礎上採取「排除法」來解答。根據上下文可以得知：此句的真正含義是「任何新事物的產生都是建立在原有事物基礎之上的」。據此，A項認為「我們很少能創造新事物」，顯然只是句子的字面意思，不正確。B項「創造新事物 是一個神話」，也為字面理解。再看C項「只有在原有事物基礎之上才能創造新事物」，這不正是我們分析得出的結論嗎?而D項「我們幾乎不可能看到新事物」，更是差之甚遠。這樣就 可確定C項為正確答案無疑。
29.答案C。先找有關細節。此問題涉及到對文章第三段最 後一句的理解。作者認為「獲得新思想並不意味著就能夠將其付諸實踐，暗含「知易行難」的意義。這樣，我們就可對 選項進行分析選棄了。這樣就可確定C 為正確答案無疑。
30.答案B。首先快速通讀全文***注意主題句***，可知文章主 要談論的是「創造力的含義及其三個方面的表現」，整篇文章都是圍繞創造力展開的。現在來分析選項。這樣就可確定，B項為正確答案。
大學四級考試閱讀訓練題***二***
When I was studying at Yale, some phenomena puzzled me greatly. I found that Chinese students or Asian students were very polite in class while American students often interrupted the professor, asking questions and dominating the discussion. The Chinese students were not as aggressive as American students.
I was impressed by the role of the professor in the seminar***討論會***. The professor didn』t act as an authority, giving final conclusions, but as a reseac her looking for answers to questions together with the students. One lingui stic***語言的*** feature of his interacting with his students was that he used many modal***情態的*** verbs—far more than I did in Beiwai. When answering questions, he usually said, 「This is my personal opinion and it could be wrong.」 or 「You could be right, but you might find this point of view also interesting.」
In China, authorities are always supposed to give wise decisions and correct di rections. Therefore, students always expect the professor to give an answer to th e question. I still remember how frustrated they were when foreign teachers did not provide such an answer. Their expectations from authorities are much higher than that of American students. Once the Chinese students got the answer, they w ere sure about it.
Ecation in China is valued for united thinking. I remember American teachers who taught in our university plaining about the fact that Chinese students u niformly expressed the same idea in their English position. The examinations in America usually do not test a student』s ability to memorize the material but his ability to *** yze and solve problems. Ecation in America is valued not on ly as a means to obtain employment but as a process of enhancing critical thinking.
31.In the USA, when the students are in class, ____.
A.a Chinese student tends to be very active B.an American student likes to make trouble
C.a Chinese student likes to puzzle the teacher D.an American student tends to be vigorous
32.A teacher in the USA prefers to ____ when he answers questions.
A.be very sincere B.be very direct
C.be very self confident D.be very indifferent
33.What is the opinion of the author concerning the difference of teachin g methods between China and the USA?
A.He thinks that Chinese teaching metods can make students learn more.
B.He holds that the major purpose of Chinese teaching methods is to impro ve students』 remembrance.
C.He thinks that American teaching is ability oriented.
D.He holds that American teachers hate to give a test.
34.The author thinks that the relationship between the student and the te acher is ____.
A.more intimate in China B.closer in China C.looser in USA D.more harmonious in USA
35.The ecation in USA may proce some ____ graates.
A.talkative B.conventional C.creative D.imaginative
大學四級考試閱讀訓練題答案
31.答案D。在文章中找到有關的細節為解此題的關鍵。從文章第一段的最後兩句可得知「中國留學生在課堂上表現很有禮貌和節制，而美國學生則非常主動和活躍。」據此看D項 「美國學生經 常表現得非常活躍」，正是我們與作者得出的結論，所以是選項無疑。解答此題也給了我們一個啟示：某些干擾項迷惑性很大，不能一眼識別，所以在選擇時可能需要進行反復比較思考 ，方能斷定其正確與否。
32.答案A。文章第二段是解答問題的關鍵。此段主要談論 「美國教授在上課時扮演的是與學生平等的角色」，並介紹了「這種情況的種種表現」。現在，我們來看選項。A項「 非常誠懇」，符合事實，先標出，看有沒有更合適的。B項「非常直接」，顯然不對，即使 美國老師語氣委婉，也只是「不直接」。C項意為「非常自信」，文章沒有提到這一點，也不能選。再看D項「非常冷淡」，更是荒謬。這樣也就只能選A。
33.答案C。解答此類題目，首先也必須象解答「有關文章主要內容題目」一樣，首先應掌握全文的主旨和大意，據此才能在理解作者觀點時，不致管中窺豹，以致偏頗。迅速通讀全文，可知作者意在抨擊中國教育方式的弊端。這樣，作者的觀點也就昭然若揭了。現在看選項。C項「美國教育重在培養學生能力」。 作者在對中國教育抨擊的同時，也對美國教育的某些做法表示贊成，而這一點正是作者對美國教育考查後得出的結論之一，所以正確。
34.答案D。推理***斷***題屬於要求較高的題型。它要求學生不僅能正確理解文章***或某些細節***，也要能據此進一步推測其中暗含的意思。D項說「美國師生之間關系和諧」，正合作者的看法，所以只能選D。
35.答案C。此題的問題太寬泛，只能根據選項，結合文章，進行取捨。C項是「具有創造力的」，美國平 等式的、自由、寬松的教育方式，鼓勵學生培養獨立分析、解決問題的能力，這樣培養出來的學生勢必多具有「創造力」，符合事實。所以選項為C。

Talent Show
Nowadays, talent shows have occupied a good proportion of screen time. Participants compete in various fields, such as singing, acting and cat walking, etc. The winners not only get grand prix but also gain promising career prospects in the entertainment instry. People hold diversified opinion about talent shows. According to a survey concted in X city, 59% of the interviewees believed that they did more good than harm, whereas 41% opposed it.
現在，選秀節目占據了電視播出時間的很大一部分。參與者在各個領域競爭，比如 唱歌 、表演、走貓步等等。獲勝者不僅能得到大獎，而且能在娛樂界獲得很有前途的職業前景。人們對選秀有各種各樣的看法。根據在X市所做的調查，59%的受訪者相信選秀是利大於弊，然而有41%的人表示反對。
The people in favor of the shows believe that they have given participants an equal chance to bring forth their talents. Talent shows in general provide a platform for people who want to stand in the spotlight. Besides, such programs are usually interactive with audience who vote out the winners. Despite the economic gains, many people dislike such contests, holding that the vulgar competition encourages an unhealthy thinking among the young people of becoming famous ovemight.
支持選秀的人認為它們給參賽者一個平等的展示天分的機會。選秀節目通常為那些想站在聚光燈下的人提供一個平台。此外，這種節目一般會與觀眾互動，由觀眾投票選出獲勝者。盡管經濟在增長，有許多人不喜歡這種比賽，他們認為低俗的比賽助長了年輕人中想一夜成名的不健康想法。
In my opinion, talent shows are no doubt a commercial success and an entertainment feast. And it is all too easy to label them as "vulgar" or "biased". Though I do have some reservation towards them, I believe that the programs themselves are not harmful， as long as run properly and viewed with a light heart of enjoyment. (206 words)
我認為，選秀節目無疑是個商業上的成功和娛樂盛宴。而且給它們貼上“低俗”或“有偏見”的標簽太草率了。雖然我確實對它們有一些異議，但我相信只要合理操作並且用欣賞的輕松心態來看待，節目本身沒有害處。

科學家尋找礦物的專屬區域
Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's 11 one of the scientists wrote in his book, "Look here for 12 metal. " Scientists in another airplane, flying over a mountain region, sent a 13 to other scientists on the ground, "Gold possible. " Walking across hilly ground, four scientists reported, "This ground should be searched for metals. " From an airplane over a hilly wasteland a scientist sent back by radio one word, "Uranium. "
None of the scientists had X-ray eyes: they had no 14 powers for looking down below the earth's surface. They were 15 putting to use one of the newest methods of 16 minerals in the ground—using trees and plants as 17 that certain minerals may lie beneath the ground on which the trees and plants are growing.
This newest method of searching for minerals is 18 on the fact that minerals deep in the earth may 19 the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were g and put into boxes. Each bag and box was 20 marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.

人類大腦智力的決定因素
There are two factors which determine an indivial's intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an indivial will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the indivial— the sort of environment in which he is brought up. If an indivial is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.
The importance of environment in determining an indivial's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(撫養) homes. Peter was raised by parents of low intelligence in an isolated community with poor ecational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

我的朋友索菲亞布倫特
Sophy Brent came to visit me nearly every day. She made me feel uneasy most of the time. She smoked 11 and never used an ashtray. She followed me into the kitchen while I made tea or coffee or supper and 12 herself to the children's orange juice. She made a great hit with my two-year-old daughter Flora, who would 13 about her for hours and refer to her lovingly as "sofa", and she was always talking about my husband and asking me where he was.
I could not decide why she chose my 14 , although I realized that nobody else paid her very much attention. Her situation was very difficult in that she was 15 out of drama school and only nineteen, but being 16 to play a leading part in a company of fairly 17 and experienced actors. They would not have liked her much even if she had been good, and as, from all accounts, she was not good so they took every 18 to run her down. I think she thought that I was the only person around who was both unconnected with the theatre and tolerably 19 . To associate with me was not, at any rate, to step down the scale. And for my part, although I felt troubled by her I did not dislike her. There was something genuinely outstanding in her personality, and she had such physical 20 that with me she could get away with anything. She was nice to have around, like flowers or a bowl of fruit.
