　　5、限制性定语从句举例：

　　注意：as和which 引导的非限定性定语从句的比较：

　　1）非限定性定语从句位于句未，而且as 和which 在从句中作主语、宾语、表语时可互换。

　　He is a farmer, as/which is clear from his manner.

　　This elephant is like a snake, as/which anybody can see.

　　2）which 引导的非限定性定语从句一般放在句未，而as 引导的非限定性定语从句可放在句未，也可放在句中、句首。放在句首时不能用which 替换,只能用as。

　　Crusoe lost his dog, which made him very sad

　　Taiwan is part of China, as/which is known to all.

　　As we have seen, oceans cover more than 70 percent of the earth.

　　3）as引导非限定性定语从句时，意为“这一点、这件事” “正如…”，常与see，hope，expect，know，guess等动词搭配；而which引导非限定性定语从句时与主句有一种因果关系，可译为“所以……”。

　　The color, as you all know, is dark red.

　　Bamboo is hollow, which makes it very light.
