定语从句里which的成分
which在定语从句中做什么成分?
which在定语从句中做什么成分?
which在定语从句中是关系代词,在从句可以作主语或者宾语。当which作宾语时可以省略。
例句:
1.A plane is a machine which can fly.
which在从句中作主语,指代先行词machine.
book which I bought last Sunday is very intetesting.
which在从句中作宾语,指代先行词book.关系代词作宾语可以省略。
was late for school again, which made his teacher very angry.
which在从句中作主语,指代整个主句.
which that在定语从句中必须充当成分吗?
which和 that在定语从句中必须充当成分。作用关系代词,它们一般在从句中作主语、表语或宾语,除个别情况,可以替换使用,做宾语时,可以省略。例如:
The building that / which is being built will be our library.正在被建的那座楼将是我们的图书馆。
This is the book (that/which) he gave me.这是他给我的书。
定语从句的三大特点?
定语从句又称为形容词性从句.
定语从句在句子中起定语作用,修饰一个名词或代词,有时也修饰一个句子.
(就像形容词修饰名词那样,如 a happy boy, happy是形容词,修饰名词boy.一个男孩,具体是什么样的小男孩,就由形容词happy来修饰boy,happy在短语中做定语,限定boy的特征,一个快乐的男孩.)
同样道理,定语从句也是用来修饰名词等,限定名词的特征.
但是与上面所举的短语例子不同的是,定语从句必须放在先行词后面.(先行词就是被定语从句修饰的词.)
如:This is the place which we visited.
这句话中,which we visited是定语从句, the place是先行词,
定语从句修饰先行词the place,这是一个地方,是怎么样一个地方呢?就由定语从句来说明,#34这是我们参观过的地方#34.
还有一个要点就是定语从句的引导词,定语从句由关系代词或关系副词引导,关系词充当从句的成分.
which就是关系代词,在定语从句中做宾语.
因为从句we visited.缺少宾语,所以由which充当,完整表示为
we visited the place.
