二、表语从句的引导词
(一)从属连词that、whether、because、as if/thugh引导的表语从句
1．that引导的表语从句，that在从句中不作任何成分，没有任何意义，但不可省略。
◆The truble is that she desn't knw hw t adapt t the new schl.
麻烦的是她不知道如何适应新学校。
◆My advice is that we shuld get there by train.
我的建议是我们应乘火车到那儿。
2．whether引导的表语从句，意为“是否”。
◆The questin is whether yu can d the wrk well.
问题是你能否做好这项工作。
◆The questin remains whether they will be able t help us.
问题是他们能否帮助我们。
if不能引导表语从句。
3．because引导的表语从句，说明主语所表示的事件发生的原因，意为“因为”。
◆That's because yu dn't knw hw t handle this kind f crisis.
那是因为你不知道如何应对这类危机。
◆She didn't pass the exam.That's because she didn't g ver her lessns.
她没有通过考试，那是因为她没有复习她的功课。
4．as if/thugh引导的表语从句，从句表示的情况发生的可能性比较小时，常用虚拟语气。
◆Lk at the sky! It lks as if it is ging t rain.
看看天空！ 看来天要下雨了。
◆The huse was in such a mess—it lked as thugh a bmb had drpped n it.

三、注意事项
1．why和because引导的表语从句的区别。两者都可引导表语从句，前者强调结果，常构成that's why...句式，意为“那是……的原因”；后者强调原因，常构成that's because...句式，意为“那是因为……”。

◆The reasn why the injectin needs repeating every year is that the virus changes.
每年需要重新注射的原因是该病毒会变化。
3．在表语从句中，主句中的主语为rder、request、advice、suggestin、prpsal、idea等表示间接的命令、要求、请求、建议、决定等意义的名词时，表语从句要使用虚拟语气，即谓语动词形式为“shuld＋动词原形”，其中shuld可以省略，表示虚拟语气。
