it is+n+that从句 是名词性从句吗that可省吗？

Question

it is a good thing my aunt went out.

Answer 1

这个句子可以有两种理解，第一种是名词性从句，其中that不可以省掉，这是个主语从句。在名词性从句中除过宾语从句，其它的几个里that 是不可以省掉的。另一种是强调句，强调that绝对是不可以省的。

Answer 2

这是强调句的句型，that 不可以省略。
（一）强调句句型
1、陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其它部分。
e.g. It was yesterday that I met my classmate.
2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that I met my classmate?
3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？
e.g. When and where was it that you were born?
4、强调句例句：对I met my classmate at the bus station yesterday.句子进行强调。
强调主语：It was I that (who) met my classmate at the bus station yesterday.本回答被网友采纳

是it作形式主语的一种，that引导真正的主语从句，一般不能省
