语法重点——定语从句
1．由which引导的定语从句：（which在从句中作主语或谓语动词的宾语）
This is the store which opens all night.
This is the pen which my brother bought for me.
Is this the house in which Lu Xun once lived?
(or: Is this the house which Lu Xun once lived in?)
This is the magazine which you are looking for.
Notes: which, whom在从句中作介词的宾语时，介词一般可置于关系代词之前或放在从句原来的位置。但在含有介词的动词固定短语中介词只能放在原来的位置上，而不能放在which之前，如例4则不能改为
This is the magazine for which you are looking.
2．由that引导的定语从句：
在定语从句中that可以指人或物，代替who，whom，which；在从句中可以作主语、宾语，但不能放在介词后作介词宾语。
This is the photo that (which) I took in Beijing last year.
This is the man that/who lives next door.
Is this the professor that you talked about yesterday? (about不能放在that前面)
但下列情况只能用that。
l）序数词或最高级形容词修饰先行词时用that。
This is one of the best novels that I have ever read.
The first English song that I learned was the ABC song.
2）all ,much, everything, nothing, something, anything作先行词时用that。（但先行词是everybody，everyone时因应用who，one指人时也用who）
Everything that we saw at the exhibition greatly interested us.
Is there anything that belongs to you?
All that we need is more time.
Nothing that parents do doesn’t influence their children.
3）先行词为any，no，only，every等修饰时用that。
That is the only way that we can find at present.
This is the very museum that we visited for the first time.
4) that可以用来引导限制性定语从句，当它在从句中作介宾时，介词应后移。
This is the good student that the teachers talked about just now.
5）先行词为既指人又指物的并列名词时，用that．
My mother and her old friends talked of the things and persons that they remembered in the school.
