2016年职称英语备考:定语从句
句型1:
由as引导的非限定性的定语从句。如:
As we have known,he is a most good student.众所周知,他是个很好的学生。请比较:It is well-known that he is a most good student.(前一个是定语从句,而后者是个主语从句。)
句型2:
由which引导的非限定性的定语从句。如:
He is a professor,which I have been looking forward to becoming. 他是个教授,那是我一直盼望的职业。(因为先行词professor是表示职业的名词,因此引导词用which,而不用who。
句型3:
由where,when引导的定语从句(其中包括限定性的或非限定性的。)如:
This is the house where I used to come.请比较:This is the house which /that I used to come to.
This is the day when I joined the Party.请比较:This is the day which /that I joined the Party on.
(说明:关于that与which之间的区别,请看关系代词that和which的区别。)
