二、表语从句的引导词
引导词 | 用法 | 例句 | |
从 属 连 词 | that，whether (不能用if) | 在从句中不作成分，that没有实际意义，不可省略；whether意为“是否” | The trouble is that she doesn't know how to adapt to the new school.麻烦的是她不知道如何适应新学校。 The question is whether you can do the work well. 问题是你能否做好这项工作。 |
because | 说明主语所表示的事件发生的原因，意为“因为” | If we travel abroad，we prefer to stay in five-star hotels.That's because they can provide guests with the best service. 如果我们出国旅行，我们更喜欢住在五星级酒店。那是因为他们能为客人提供最好的服务。 | |
as if/ though | 从句表示的情况发生的可能性较小时常用虚拟语气 | Every time I listen to the music，it feels as if a picture of a river is spreading before me.每当我听这首音乐的时候，感觉就像一条河的画面在我面前铺开。 | |

That is why English has so many difficult rules that confuse people.

我缺席的原因是我必须照顾我的小妹妹。
3．表语从句中的虚拟语气。
在表语从句中，表示间接的命令、要求、请求、建议、决定等，主句中的主语通常是：advice，suggestion，proposal，request，order，desire，demand等，从句谓语形式是“should＋动词原形”(should可以省略)。
