　　what引导的从句

　　what在英语中非常活跃,它可以用来引导主语从句、宾语从句、表语从句，但是不用来引导定语从句。在句子里可以充当主语、宾语、表语、定语，既可以指人，也可以指物。

　　[例句

　　What is the population of the world? 世界的人口有多少?

　　What did you pay for this picture? 这幅画你付了多少钱?

　　What is most important in life isn’t money. 人生最重要的并非是金钱。

　　Will you show me what you bought? 可以把你所买的东西给我看一下吗?

　　Mary is no longer what she was ten years ago. Mary已经不是10年前的她了。

　　as引导的非限制性定语从句

　　在as引导的非限制性定语从句中，连接代词as在句子中可以作主语、宾语或表语等，可以指人或物。其在定语从句中的位置比较灵活，即可以在句子前面，在句子中间或句子末尾。常用的结构有：as we all know; as is well known to…; as is often the case; as is said/mentioned above; as has been said before; as I told you before; as is evident; as often happens; as can be seen; as is/was expected; as we expect; as I can remember等。

　　[注意1]as通常只指整个句子的内容，不表示部分内容。

　　[注意2]as引导的非限制性定语从句通常指“事先可以预料到的”“料想到的”，表达“好”的方面。

　　[注意3]as引导限制性定语从句时，常构成the same…as…; such…as…; so/as …as…等结构。在从句中既可以指人、物，也可以指整个句子。

　　[例句]

　　This is also part of your work, as I told you before. 我曾告诉过你，这也是你工作的一部分。

　　The man was a teacher, as was evident from his way of speaking. 从那人说话的样子可明显看出，他是个老师。

　　Such ideas as he hits on are worthless. 像他那样偶然想起的主意是无用的。

　　It’s the same story as I heard from her yesterday. 这故事跟我从她那儿听到的相同。

　　He will marry as pretty a girl as he can find. 他要尽可能找漂亮的女孩结婚。
