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。

高中英语语法高考二轮复习it考点讲义【精讲版】it用作形式主语和形式宾语的用法归纳总结一、用作形式主语当不定式、动名词、从句等用作主语时，避免头重脚轻，通常在句首使用形式主语厄而把真正的主语放在句子末尾。
如：It is stupid to do such a thing.做这种事真蠢。
It's no good sitting up too late.熬夜没有好处。
It is necessary that he should be sent there at once.有必要马上派他到那里去。
注：类似以下句子中的il也可视为形式主语：It happened that the harvest was bad in 1988.碰巧1988 年的收成很不好。
It seems that she is afraid to tell them about it.似乎她怕将此事告诉他们。
二、用作形式宾语当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时，就应在宾语补足语前使用形式宾语，而将真正的宾语移至句末。
如：I've made it a rule never to hurry,我已养成凡事从容不迫的习惯。
Do you think it possible to root out crime?你认为可以根除犯罪吗？He found il difficult to breathe at high altitudes.他觉得在高空呼吸困难。
注：通常意义的形式宾语主要见于真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形，即用于“动词+it+宾语补足语+真正的宾语”这样的结构，但以下两类形式宾语却比较特殊，其后没有宾语补足语:1.由于介词后通常不能直接跟that从句作宾语，有个别特殊结构就在介词后先接it作形式宾语，再跟that从句。
如：You may depend on it that it is true.你可以相信这是真的。
