This is what they are talking about .为什么要是that is

This 是这个,
that 是那个.
要看场景.比如说,他们在讨论的是你们现在可以看到的东西,比如他们在讨论这个新桌子.那么你可以指着这个桌子,对另外一个人说：This is what they are talking about.
但是一般用 that.因为他们讨论的东西,可能你是用语言向第三个人转述,所以,未必有实物在眼前可以看到.那么你就用　that 来指代他们讨论的内容.

这个句子没有语病 , 是正确的！

都可以啊，都是表语从句。

我认为是THIS IS ，凭语感。

这个句子没问题。

都没问题。this、that做指代，只是有近远之别，this"这是"指近的那个，that“那是”指远的那个。
