高中英语语法知识之It的用法总结
高考英语语法知识之It 的用法总结1. It is + 被强调部分+ that ...该句型是强调句型。
将被强调的部分放在前面, 其它部分置于that之后。
被强调部分可以是主语, 宾语, 状语。
强调的主语如果是人, that可以由who换用。
如果把这种句型结构划掉后, 应该是一个完整无缺的句子。
这也是判断强调句型与其它从句的方法。
I.wa.the.tha.(who.cleane.th.classroo.yesterday.I.wa.i.th.stree.tha..me.he.father.2. It was not until + 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.no....unti....的强调形式. It was not until she took off her dark glasses that I realized she was a famous film star.= Not until she took off her dark glasses did I realize she was a famous film star...didn’.realiz.sh.wa..famou.fil.sta.unti.sh.too.of.he.dar.glasses.3. It is clear ( obvious, true, possible,certain....)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。
It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear.4.I.i.importan..necessary.right.strange.natural....tha....由于主句中的形容词不同, tha.后的从句中要用虚拟语气（shoul..动词原形）, shoul.可以省去。
