高中英语语法的学习是我们在高中阶段学习英语要解决的一个重要的方面，因为我们要想学习好英语，我们就要把英语的语法熟练的掌握了，然后再去进行其它的学习，这样才能更加有效。所以，我们还是要很好的掌握下面的学习方法，还有一些重要的句子，类型等的。

★ what不能引导定语从句 / sth that =what all that =what

当第一要素"先行词"是指代物的名词或代词时,其后的定语从句的引导词用that 或which在定语从句中作主语或宾语

e.g. A plane is a machine (that / which can fly.)

物 ↘ 作从句中的主语

The noodles (that / which I cooked )were delicious.

物 ↘ 作从句中的宾语(可省略)

当第一要素先行词是指代人的名词或代词时,用that 或 who在定语从句中作主语,用that /who/whom 在定语从句中代替宾语

e.g. The foreigner( that/who visited our school yesterday) is from Canada.

↘作从句中的主语

The girl (that/who/whom you saw yesterday) is Jim's sister.

↘作从句中的宾语(可以省略)

关于定语从句中可以作介词宾语的引导词

只有引导词which ,whom才可在定语从句中直接跟在某一介词的后面作宾语.

e.g. The athlete( to whom you talked) is a famous runner.

↘介词 ↘只用whom不用who 代人athlete

This is the room( in (介词) which he lived 3 years ago.) (其中in which 可以用where换,)

★但介词也可留在原词组中,上句也可如下表示:

The athlete (that/who/whom you talked to )is a famous runner.

This is a room (that/which he lived in 3 years ago.)

注:常见的不可分拆的词组有:take care of , look after, look for, catch up with, keep up with

look out for ,catch sight of etc.

当第一要素先行词是指人或物的名词或代词,在定语从句中修饰别的名词时都用whose 来代替人或物,意为"他(们)的,或它(们)的"在从句中作定语.

e.g. This is a door (whose color is brown).

↘代替了"门的 "修饰color 在从句中作定语

Harry is the boy( whose mother is our maths teacher.)

/ Harry is the boy, the mother of whom is our maths teacher .

↘ 代替"男孩的" 修饰mother 在从句中作定语

/Harry is the boy ,of whom the mother is our maths teacher.

稍难例句

The child was saved by a man ,the name of whom/whose name/of whom the name was unknown.

There are 54 students in our class, 25 of whom are girls /相当于 of whom 25 are girls.

The Greens have two daughters, both of whom /of whom both are college students.

The journey around the world took the old sailor nine months, of which the sailing time was 226 days./ /相当于/the sailing time of which was226days

或 226days of which was the sailing time./

注意以下句子: (多样化例句)

The beggar has no money with which he can buy food .

/The beggar has no money which /that he can buy food with .

The beggar has no money with which to buy food.( 引导词后直接跟了不定式短语)

/The beggar has no money to buy food with

The peasants built some stores in which to store their grain. (可以模仿以上例句举一反三)

★在有些定语从句中常只能用that引导定语从句,而不能用who/whom/which与它互换.

当第一要素先行词中既有人又有物时

e.g. I still remember the school and the teachers (that he mentioned yesterday.)

当第一要素先行词是指物的不定代词 如anything , all , everything, much, something. (sth that =what all that =what)

e.g. All (that /can be done) has been done(能做的一切都做了)

/What can be done has been done

I can do all (that )/what I can║ to help you.

that可省因为它在定语从句中作宾语

Jack is no longer the lazy boy that he used to be

/Jack is no longer what he used to be .

Shanghai is no loner what it used to be

/Shanghai is no longer the city that it used to be. .

当第一要素先行词中带有the only, the very 修饰物时

e.g. He was the only person( that knew about the secret.)

4. 当第一要素先行词中有序数词或形容词的最高级时

e.g. This is the first book〔 (that) I have bought.〕

This is the best film (that )I have ever seen

5. 以疑问词who, which 开头的疑问句为避免重复

Who is the boy( that is talking to our headmaster )

Which of us that knows something about physics does not know this

一般只能用who的搭配anyone who , he who, anybody who,

Anyone who /He who /Whoever doesn't reach the great wall is not a true man.

★ 注意下句的先行词和主句的谓语单复数

He is the only one of the teachers who /that knows French in our school.

He is one of the teachers who/that know French in our school.

当第一要素先行词是指时间的名词时,其后的定语从句的引导词一般用when,在定语从句中作时间状语.

e.g. I still remember the day ( when I first came to Beijing.)

↘表时间的名词 ↘作从句中的状语"在那天"

当第一要素先行词是指地点的名词时,其后的定语从句的引导词一般用where在定语从句中作地点状语.

e.g. The factory (where his father works )is in the west of the city.

↘表地点的名词 ↘作从句中状语"在那家工厂"

★ ★ case ,point situation ,scene 等是表示地点的抽象名词,其后的定语从句常常用where引导

当第一要素先行词是reason 时,其后的定语从句的引导词一般用why (the reason why) 在定语从句中作原因状语.

e.g. There are several reasons( why we can't do that).

★**但并非看到先行词是指时间或地点的名词及reason 时,就马上用引导词when ,where or why ,要看在定语从句中缺少了什么成份,如果第一要素"先行词"的确是时间或地点的名词及reason,就立刻分析第二要素"成份",如果定语从句中缺少了成份主语或宾语,这时只能把先行词第一要素时间或地点的名词及reason,看作指物的名词,然后选择第三要素"引导词"用that/which 而不能如例句"五,六, 七"中用when ,where, or why .

e.g. I still remember the day (that/which we spent (度过) together ) last summer.

↘表时间的名词 ↘在定语从句中作spent的宾语故不用when

The factory (that / which we visited last week) is my father's.

↘表地点的名词 ↘ 在定语从句中作visit 的宾语,故不用where

The reason (that /which was given by him) was right.

↘表原因 ↘在定语从句中作主语,故不用why

***还要注意典句 The reason is that ………是表语从句

eg. The reason is that he has difficulty in learning English .

The reason (why he is late for school) is that he missed the early train.
