分隔式定语从句
定语从句一般紧跟在先行词之后,但有时会被其他句子成分与先行词隔开,从而构成分隔式定语从句。 The days are gonewhen power politics worked.
介词+关系代词(which/whom等)引出的定语从句
如果关系代词(which/whom等)在定语从句中作介词的宾语,那么这个介词可以提到从句前,构成“介词+关系代词(which/whom等)+定语从句”。在这种结构中关系代词不可以用that。
The four travelers with whom I shared the room were pleasant people.
as引出的限制性定语从句
在such as的结构中as可作关系代词,引出限制性定语从句。有时和same用,在从句中可作主语、宾语或表语等。
I have the same trouble as you (have).
as引出的非限制性定语从句
as可作关系代词引出非限制性定语从句,代替整个主句,通常译为“(正)如一样”,“(正)象一样”等。as引导的从句一般用逗号与主句隔开,可以位于主句的前面、中间或后面.
As is generally accepted, economic growth is determined by thesmooth development of production.
非限制性定语从句
非限制性定语从句修饰先行词或整个主句,起补充说明的作用,如果省略掉,原句句意仍保持完整。非限制性定语从句要用逗号与主句隔开,其引导词不能用that。非限制性定语从句属于正式语体。非限制性定语从句有以下三种。
由“介词+关系代词”引导的非限制性定语从句。
He failed to pass the exam, because of which his parents scolded him.
由“数词、代词或名词+of +关系代词”引导的非限制性定语从句
There are about twenty students in this course, most of whom arefreshmen.
由which、as引导的非限制性定语从句。which、as代表整个主句。
Hesaid that he had never seen her before, which was not true.
