That she was able to come made us very happy为什么要加个that

问题描述:

That she was able to come made us very happy为什么要加个that
不加that句子不是也是完整的嘛?

1、that 引导的是主语从句she was able to come2、that引导的主语从句如果位于句首,则that不能省略,你的这句就是这种情况3、若that引导的主语从句位于句末,而在句首使用了形式主语it,则that可以省略,如:It&nbs...什么时候句子前要加that?
she was able to come made us very happy
如果不加that句子是不是要变成she was able to come to make us very happy?如果作为主语从句come之前是完整主语,因此和made之间就不用加东西。

要改成:It  made us very happy (that)she was able to come

也就是说,这句有二种表达 方法:

1、位于句首的表达方式 

That she was able to come made us very happy

因为:that引导的主语从句如果位于句首,则that不能省略,去掉that是错误的。

2、位于句末的表达方式 

It  made us very happy (that)she was able to come

因为:若that引导的主语从句位于句末,而在句首使用了形式主语it,则that可以省略


这种主语从句,只有这二种表达方法。
