高中英语语法专题第二十三章 it的用法和There be结构
第二十三章 it的用法在英语中，it的使用相当广泛，它既可以用作代词 (如人称代词、非人称代词)，也可以用作引导词，还可以用在强调句型中。
用它所构成的句型是历届各类考试中的热点。
一、it作人称代词这时it指前面已经提到过的人或事物，it作真实主语或宾语。
如：He went upstairs and knocked at the door. The man opened it. 他上楼敲门，那人打开门。
He took off the first shoe and threw it on the floor.他脱下第一只鞋子，把它扔在在地板上。
I've lost my ruler. Have you seen it anywhere?我的尺子丢了。
你在哪看见它了吗?二、it作非人称代词这时it作主语，表示天气、温度、时间、距离等。
这时it的语法功能是明确的(作主语)，而意义却是含糊的，所以有人把它称为"虚义it"。
如:It's going to be dry and sunny for the next two days.未来两天天气干燥晴朗。
(表示天气) It's February 24th today.今天是2月24号。
(表示日期)Is it very far from your home to the school? 你家离学校远吗?(表示距离)How cold is it outside? 外面冷到多少度?(表示温度)It was dull when Mary was away.玛丽不在，真没劲。
(表示一般笼统情况)三、it作形式主语为了避免将句中作真实主语的不定式短语、-ing形式短语和主语从句置于句首造成头重脚轻，习惯上用it作形式主语来指代后面的真实主语。
(一)代替不定式短语It's best to plant trees in spring because it's warmer.春天是植树的最佳时节，因为天气更暖和。
