该句式 有四种情况。
1、that从句是定语从句
2、that从句是主语从句
（既然说的是that从句，第四种情况可排除掉。）
It is the best film that I have ever seen。（定语从句）
It is a good idea that we go to the cinema。（主语从句）
It is the very news that our team has won。（同位语从句）
扩展资料：
1、It is / was＋被强调的部分＋that(who)+剩余的部分。
如：It wasn’t until he came back that I went to bed。直到他回来我才睡觉。(一定要注意被强调句型谓语动词否定的转移，及形式)。
It was because he was ill that he didn’t come to school today.只因为他有病了今天没有来上学.（只能用because而不能用for,as 或since）
It is I who am a student.我确实是个学生。（句中am不能用are来代替）
2、It is high time (time/ about time) (that) 主语＋should do / did+其它。（注意从句中的谓语动词用的是虚拟语气）
It is high time that we should go / went home。我们该回家了。
It is a pity that you can't come to my party. 很遗憾你不能来我的聚会。rui
It is the best film that I have ever seen.（定语从句）
It is a good idea that we go to the cinema.（主语从句）
It is the very news that our team has won.（同位语从句）追问
你好，我想再问一下
如果这个名词是抽象名词，后面的句子用虚拟语气吗，写几个例句，谢谢
如果我的问题是错的，可以的话就揣测一下我想问的东西，谢谢啦
追答It is (high) time that后面的从句谓语动词
要么用过去式或者用should+动词原形,但should不可省略.
如：
It is high time that the children went to school.
It is high time that the children should go to school.
再如
It is no surprise that Tom should have won the match,
