it做形式主语的个句型
i t做形式主语的个句型集团档案编码：[YTTR-YTPT28-YTNTL98-UYTYNN08]1.Itis/was+被强调部分+that/who...该句型是强调句型。
被强调部分可以是主语，宾语，表语或状语。

2.Itisnotuntil+被强调部分+that...该句型也是强调句型。
主要用于强凋时间状语，译成汉语“直到……才……”，可以说是not...until...的强调形式。
Itwasnotuntilshetookoffherdarkglasses thatIrealizedshewasafamousfilmstar. =NotuntilshetookoffherdarkglassesdidI realizeshewasafamousfilmstar.=Ididn'trealizeshewasafamousfilmstaru ntilshetookoffherdarkglasses.3.Itisclear/obvious/true/possible/cer tain…that…该句型中it是形式主语，真正的主语是that引导的主语从句，常译为“清楚（显然，真的，肯定……）”是主语从句最常见的一种结构。

由于主句中的形容词不同，that后的从句中要用虚拟语气（should+动词原形），should可以省去。
