初中英语定语是什么怎么用

『壹』 初中英语：定语从句的用法

1.what不能引导定语从句.
2.关系词的分析须考虑它在定语从句中的成分。
一.指人的关系代词有who、whose、whom、that. 试分析：
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. （=The man who/whom that my father shook hands with just now is our headmaster.）注：
A．指人时有时只用who不宜用that。
1．先行词为one、ones或anyone
（1）The comrade I want to learn from is the one who studies hard and works hard.
（2）Anyone who breaks the law should be punished.
2．先行词为these时
These who are going to Beijing are the best students of our school.
3．在there be 开头的句子中
There is a student who wants to see you.
4．一个句子中带有两个定语从句，其中一个定语从句的关系代词是that，另一个宜用who，以免重复。
The student that won the first prize is the monitor who works hards.
5．在非限制性定语从句中
A。I met a friend of mine in the street, who had just come from Japan.
B．主句以who开头的句子中,只用that,不用who。
二．指物的关系代词有which、whose(=of which)、that. 试分析：
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
注：
A. 介词如果位于作为其宾语的关系代词之前时，只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短语动词中的介词不可与动词拆开，在定语从句中其介词不可前置，只能放在其动词之后。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping’s son.
C．指物时，下列情况下只能用that ，不宜用which。
（1）先行词为不定代词，如All、much、anything、everything、nothing、something、none、the one等。
We are willing to do anything that is good to the people.
I have told them all (that) I know.
All that can be done has been done.
（2）先行词是序数词或被序数词、修饰时。
The first book that I read last night was an English novel.
（3）先行词是形容词最高级或被最高级修饰时。
This is one of the most interesting films that I have ever seen.
This is the best that can be done now.
（4）如果有两个或两个以上分别表示人和物的先行词时(先行词既有人又有物)，定语从句的关系代词用which和who都不合适，只能用that。
We know nothing about the doctors and the hospitals that you are talking about.
There are sheep and men that can be seen on the hill.
（5）如果先行词被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修饰时。
This is the only book that can be lent to you.
（6）当主句是以which开头的特殊问句时，关系代词只用that。
Which is the dictionary that he used yesterday ?
D．只物时，下列情况下只能用which，不宜用that。
（1）关系代词放在介词之后
This is the factory in which we once worked.
（2）非限制性定语从句中
This is the book, which is written by Lu Xun.
（3）that，Those作主语时
Those which are on the desk are English books.
E．先行词前有such、the same、 as时, 关系代词用as，不用that, 但the same…as…表示同样的, the same…that…表示同一的
He knows as many people as are present at the meeting.
Such people as you refer to are rare nowadays.
三．比较When/which、where /which、why.
which I still never forget.
This is the day when I joined the party.
which he spent reading the books.
where I found the book.
which makes machines.
This is the place which we once visited.
which I will never forget.
which I am looking for.
限制性定语从句与非限制性定语从句的区别：
限制性定语从句
非限制性定语从句
All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了，不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了，他们学习努力。（没有人不及格，这些学生都很努力。）
从句是先行词不可缺少的定语（如去掉，主句意思就不完整或不正确。）从句是对先行词的附加说明（如去掉，主句意思仍清楚，不受影响。）与主句关系密切，不用逗号与主句关系不十分密切，用逗号与主句隔开译为汉语时，从句译在先行词前，与先行词用“的”连接译为汉语时，从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略关系代词不能省略关系代词as和which
先研究下面两个例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来，这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格，这使得他父亲很生气。
这两个例句中，as和which所代表的都是整个主句所表示的内容。但有两点不同之处：
1．在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面；而which引导的非限制性定语从句只能位于主句的后面，不能位于主句的前面。
2．在意义上，as引导的定语从句和主句的关系一般为一致关系，常译为“正如……”，“就像……”，而which引导的定语从句和主句的关系是因果关系，或which引导的定语从句是对主句的评论。因此，在意思通顺的情况下，which可代替as，而as许多时候不能代替which，如句○2。再如：
1．He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料，他又迟到了。/他又迟到了这是我们早就料到的。
2． The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了，因此整条街很脏。（不用as）
3．The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财，这是不光彩的。（不用as）
4．He takes exercise everyday, which has done a lot of good to his health. 他每天运动，这对他的身体很有好处。（不用as）
5．As has already been pointed out, English is rather difficult for a foreigner. 正如已经指出的那样，英语对于初学者说，是相当难学的。在such…as…、the same…as…、 as…、 as many…/much as…等结构中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 这样的书对于初学的人来说是太难了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大楼里。
3.He knows as many people as are present at the meeting. 他认识所有到会的人。
4.That day we all got up early as usual. 那天我们和平时一样，都起得很早。
“One of the +复数名词”后面定语从句中谓语单复数情况
这一结构后面的定语从句的谓语动词通常用复数形式，跟定语从句所靠近的那个复数名词在数上保持一致。如：
1． That is one of the books that are required for study at school.
2． This is one of the most wonderful novels that have been published since 1990.
3． She is one of the few persons who know Spanish .
4． This is one of the most famous plays that were written in the thirties,
如果one of +复数名词这一结构前面带有the only、the very之类的限定语，后面定语从句的谓语动词则要用单数形式，这是因为定语从句在意义上修饰的是而不是那个复数名词。如：
1.He is the only one of the teachers who knows French in our school.( 修饰the only one)
He is one of the teachers who know French in our school.( 修饰the teachers)
2.This is the only one of the rooms that is free now. (修饰the only one)
This is one of the rooms that are free now. (修饰rooms)
as与which引导的定语从句
两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。
1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.
2. 当与such或the same连用时，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 当从句和主句语义一致时，用as，反之则用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。
She has been late again, as was expected.
Tom has made great progress, which made us happy.

『贰』 英语中什么是定语定语的概念是什么.怎么用

定语是对句中某个名词或代词或句子进行修饰的句子成分，常由形容词、过去分词、从句等充当。

『叁』 初中英语定语是什么，什么词可以当作定语，定语可以修

定语是用来修饰、限定、说明名词或代词的品质与特征的。 主要有形容词，此外还有名词、代词、数词、介词短语、动词不定式（短语）、分词、定语从句或相当于形容词的词、短语或句子都可以作定语。 汉语中常用‘……的’表示。
定语和中心语之间是修饰和被修饰、限制和被限制的关系。
在汉语中，中心语与定语二者之间有的需要用结构助词“的”，有的不需要，有的可要可不要。 “的”是定语的标志。在英语语法中，定语有许多的运用，需要遵循很多相关规律。
在英语中，定语的位置一般遵循如下规律：前位限定词总在前面。 主观词+客观词。说话人对事物主观性评价的定语在前，客观性评价的定语在后。序数词+基数词。碰到数词定语时，一般地，序数词在前，基数词在后。少音节词+多音节词。当几个形容词同时修饰一个名词时，还可以根据行文习惯，通过音节的多少来确定定语的顺序。制作)方式+材料+用途。当有几个名词做定语时，常以这种方式排列。不定代词的定语要后置。副词做定语要后置。某些表示地点、方位、时间的副词作定语时，通常要后置。由数字构成的复合形容词做定语。名词用做定语时，通常以单数形式出现。
定语的位置一般有两种：用在所修饰词之前的叫前置定语，用在所修饰词之后的叫后置定语。
单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。
在英语里，一般定语前置时的次序为：限定词，形容词、分词、动名词和名词性定语。但当几个形容词同时出现在名词短语之前，我们要注意其次序。
其形容词遵循的词序为：限 观 形 龄 色 国 材（简称“县官行令杀国才”）
指：限定词（一般指数量）；外观（美丽等）；形状（大小，高矮，肥瘦）；年龄；颜色；国籍；材料；用途。
如：
1限定词 2 外观 3形状 4年龄 5颜色 6国籍 7材料 8用途
a famous American university
an interesting little red French oil painting
a new plastic bucket
a purple velvet curtain
an elegant German clock

『肆』 初中英语定语从句考试范围是什么

基本上考比较简单的，which,that,who,whom,whose等，指代人时用who(做主语), whom(做宾语），指物时回用which，既可指答人又可指物用that.,做定语时whose等
还有在哪些情况下用that,哪些情况用which等

『伍』 初中英语中的定语的用法

你好，一种形式是这样
形容词+名词，这里形容词就是定语
二非谓语动词作定语的情况，如Can
those
seated
at
the
back
of
the
classroom
hear
me?
这里seated就是定语，三不定式作定语
不定式作定语表示将要发生的动作
还有
限制性定语从句
限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；定语从句中可引导定语从句的关系代词有that
,
which
,
who
(宾格whom
，所有格whose
),
as。
2.
非限制性定语从句
非限制性定语从句则只是对先行词作些附加说明，主从句关系不十分密切，如果去掉从句，主句的意思依然很清楚，从句和主句往往用逗号分开。
1）一般先行词是物或无先行词时，要用which
引导，不用that。在非限制性定语从句中不能用that来代指人，而应当用who
/
whom指人。指人和指物的关系代词在定语从句作宾语时也不能省略。引导非限制性定语从句的关系代词which，既可以指代前面的先行词，也可以指代前面整个句子的含义。
2)关系代词as引导非限制性定语从句，并在句子中作定语、表语或宾语，这个定语从句可以是说明整个句子，它可以放在主句之前，也可以放在主句之后，有时还可以插入主句中，as
通常翻译成“…正如…
那样”。
