表语从句
好消息传来了。那就是我们学校要去野营。但问题是我们应该什么时候出发。我的建议是这个周末去附近的山谷。原因是这里交通方便,而且有很多景点。我们肯定会玩得很开心。(黑体部分使用表语从句)
【例文展示】

【语法感悟】
1.以上语句中的黑体部分都位于 后,作表语,故都是表语从句,这些表语从句在词性上相当于一个 。
2.句(1)、句(3)和句(4)由从属连词 引导;句(2)由连接副词
引导。
系动词be
名词
that
when
语法精讲
一、概念
在主从复合句中,充当表语的从句叫表语从句。表语从句通常位于连系动词之后,用来说明主语的身份或特征。可接表语从句的连系动词有be,look,seem,appear,remain等。
二、表语从句的引导词
从属连词 that,whether,because,as if/as though
连接代词 what,which,who,whom,whose
连接副词 when,where,why,how
1.连接词that,whether引导的表语从句
(1)that引导表语从句时,在句子中无意义,也不充当任何成分,但通常不可省略。
The fact is that he has tried his best to finish the work.
事实是他已尽了最大努力来完成这项工作。
(2)whether引导表语从句时,在句中不充当任何成分,意为“是否”,不能与if互换。
The question is whether the film is worth seeing.
问题是这部电影是否值得看。
2.连接代词引导的表语从句
连接代词what,which,who,whom,whose引导表语从句时,在从句中作主语、宾语、表语或定语。
The problem is who should be responsible for the task.
问题是谁应该对这个任务负责。
That is exactly what I’m going to talk about.
那正是我要讲的。
3.连接副词引导的表语从句
连接副词when,where,why,how引导表语从句时,在从句中作时间、地点、原因或方式状语。
The question is when he can arrive at the hotel.
问题是他什么时候能到达旅馆。
Look at the big house over there.That’s where I was born.
看那边的大房子。那是我出生的地方。
4.because,as if/as though引导的表语从句
It looked as if it was going to snow.
看起来好像要下雪了。
That’s because we never thought of it.
那是因为我们从未想过此事。
三、注意事项
1.why和because引导的表语从句的区别。
That’s why... 意为“那是……的原因”,强调结果
That’s because... 意为“那是因为……”,强调原因
He had seen the film before.That is why he did not see it last night.
他以前曾看过那部电影。那就是他昨天晚上没有去看的原因。(第一句话说明原因,第二句话说明结果)
He did not see the film last night.That is because he had to help his little sister with her homework.
昨天晚上他没有去看电影。那是因为他得帮助他的妹妹做作业。(第一句话说明结果,第二句话说明原因)
2.reason作主语或主语中包含事件的起因,后面的表语从句表示原因时,要用that而不是because引导。
The reason why he was late for work was that he didn’t catch the early bus.
他上班迟到的原因是他没赶上早班车。
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等,从句谓语形式是“should+动词原形”(should可以省略)。
The proposal is that we (should) work together for the same goal.
这个提议是,我们要为共同的目标一起努力。
