[归纳用法]
1.所有例句中的黑体部分都位于系动词be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名词。
2.例1由从属连词that引导;例2由连接代词wh引导;例3由从属连词whether引导;例4由连接副词why引导;例5由连接代词what引导。
表语从句放在连系动词之后,充当复合句中的表语。表语从句就是指一个句子作为表语,说明主语是什么或者怎么样。
一般结构为“主语+系动词+表语从句”。可接表语从句的连系动词有be,lk,remain,seem等。
1.从属连词that引导的表语从句
从属连词that的用法:①无意义 ②不充当成分
③不可省略

他缺席的原因是他没接到通知。
My suggestin is that we shuld tell him.
我的建议是我们应该告诉他。
2.从属连词whether引导的表语从句
The pint is whether we shuld lend him the mney.
关键在于我们是否应该借钱给他。

我没有给她打电话。那就是她对我生气的原因。
I didn't phne her,and that's because I gt angry with her.(强调“生气”这一原因)

[名师点津]
reasn作主语时,后面的表语从句表示原因时要用that引导,不宜用because。
6.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,suggestin,prpsal,request,rder,idea等,从句谓语形式是“shuld+动词原形”(shuld可以省略)。
