关系代词使用的几种特别规定:
1)先行词是不定代词,常见有all, much, any, something, anything等;
2)先行词被all, any, every, some,(a)few,(a)little修
3)先行词被最高级、序数词、the only/next/same/very修饰时;
4)先行词既包括人,又包括物时。
5)只用which:介词后、引导非限制性定语从句只能用which。介词 which既可以引导限制性定语从句,也可以引导非限制性定语从句,该结构中介词的选择取决于从句谓语动词的固定搭配,也取决于先行词的习惯搭配。
It is written by a person with whom we are all familiar.
This is the computer on which he spent all his savings.
6)关系代词省略情况:that、which引导定语从句作宾语可以省略。但以下情况不可省略:
第一,引导非限制性定语从句中,即使作宾语which也不能省略。
第二,关系代词紧跟介词后,作介词宾语,此时一不可用that,只可用which或whom 引导定语从句,并且不可省略;但当介词谓语定语从句句末时,作为介词宾语的关系代词仍可用that,也可以省略。
This is one of the things with which we have to put up.
This is one of the things (that/which )we have to put up with.
