That is why he succeed.At that time, it seemed as if I couldn't think of a right word anyhow.II、分类详解1、由从属连词that，whether引导的表语从句。that在引导表语从句时无词义，而whether有词义，意为、“是否”。这时主句的主语常常是些抽象名词，如question，trouble，problem，result，chance，suggestion，idea，reason等。表语从句对主句主语进行说明、解释，使主语的内容具体化。The trouble is (that) she has lost his money. The question is whether we need more ice cream.What she couldnt understand was that fewer and fewer students showed interest in her lessons. 2、由关系代词引导的表语从句。关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。The question is which of us should go.The problem was who could do the work.That's what he is worrying about.。That's what we should do.3、由关系副词引导的表语从句。Go and get your coat. It's where you left it. I had neither a raincoat nor an umbrella. Thats why I got wet through. That is how he makes that of money every year. That is what he is worried about.4、由连词because，as if/as though等引导的表语从句。It looked as if it was going to snow.That's because we never thought of it.It seems as if he didnt know the answer.巩固练习：1.
