英语中表语从句的用法归纳 1. 表语从句概说 表语从句即在主从复合句中用作表语的从句。引导表语从句的词有连词that, whether，连接代词和连接副词以及as if, as though, because等连词： My idea is that we should do it at once 我的想法是我们应该马上做。 The question is whether he is honest. 问题是他是否诚实。 The problem is how we can find him. 问题是我们如何找到他。 That was when I was fifteen. 这是我15岁时发生的事。 That's why I can't go with you. 那就是我不能同你一起去的原因。 It isn't as if you were going away for ever. 又不是你离开不回来了。 It is because I love you too much. 那是因为我太爱你了。 2. 两点重要说明 (1) whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句；because 可引导表语从句，但与之同义的since, as, for等也不用于引导表语从句。 (2) 引导表语从句的that通常不省略，但在口语或非正式文体中有时也可省略： 本文来源：https://www.wddqw.com/doc/4a032d82e209581b6bd97f19227916888486b9fc.html
