as和which引导的定语从句
As与which引导的定语从句先研究下面两个例句：○1.This elephant is like a snake, as /which everybody can see.=As everybody can see, this elephant is like a snake.任何人都看得出来，这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry.Tom物理考试不及格，这使得他父亲很生气。
这两个例句中，as和which所代表的都是整个主句所表示的内容。
但有两点不同之处：1．在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面；而which引导的非限制性定语从句只能位于主句的后面，不能位于主句的前面。
2．在意义上，as引导的定语从句和主句的关系一般为一致关系，常译为“正如……”，“就像……”，而which引导的定语从句和主句的关系是因果关系，或which引导的定语从句是对主句的评论。
因此，在意思通顺的情况下，which可代替as，而as许多时候不能代替which，如句○2。
再如：1．He was late again, as / which we had expected.=As we had expected, he was late again.正如我们所料，他又迟到了。
/他又迟到了这是我们早就料到的。
2．The street hasn’t been cleared for weeks, which makes it very dirty.街道好多星期没有打扫了，因此整条街很脏。
（不用as）3．The young man cheated his friend of much money, which was disgraceful.那年轻人诈骗了他朋友许多钱财，这是不光彩的。
