四、语法复习
复习定语从句
1.关系代词as引导的定语从句.
as可以引导限制性定语从句, 也可以引导非限制性定语从句, as在从句中可做主语, 宾语, 表语.
如:
The people as you describe are thought to be fools.
As is known to all, Edison invented the telephone.
as引导非限制性定语从句时和which的区别:
(1)as引导的非限制性定语从句可以放在句首,句中,句末; which引导的非限制性定语从句只能放在主句的后面.
(2)as经常和be, 和被动语态连用; which引导的非限制性定语从句中经常用主动语态.
(3)as多用于这些习惯用语中:as anybody can see; as is well-known; as we had expected; as often happens; as it is; as has been said before; as is mentioned
above; as is often the case. / which
2.代词/数词/名词+of \ whom引导的非限制性定语从句.
如:
I have many friends, some of whom are businessmen.
或:I have many friends, of whom some are businessmen.
