为什么要用以下介词

来源:百度知道 编辑:UC知道 时间:2024/06/23 13:37:16
1.who is the man (that) is standing over there?为什么不用who
2.That book is the one (which) I bought yesterday.为什么不用that
3.The pen (that) she is writing with is her brother's.为什么不which?
4.That is the reason (that) he gave at the meeting.为什么不用which?

请分条讲解一下,不要太复杂。
另外,which和that都可以作主语和宾语,该怎么区分?

1.避免重复
2.个人认为有点问题。The one后面应该用that。
3.that / which 均可。
4.应该用which避免重复。

以下是which和that的用法:
1. that即可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置

2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢

3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略

1)不用that的情况
a) 在引导非限定性定语从句时。
(错) The tree, that is four hundred years old, is very famous here.
b) 介词后不能用。
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.

2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中,只用that,不用which。
b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。
c) 先行词有the only, the very修饰时,只用that。
d) 先行词为序数词、数词、形容词最高级时,只用that。.
e) 先行词既有人,又有物时。

举例:
All that is need
