★★ 单元语法精讲——it的用法★★
1. it作代词
it不仅可以指代具体的物品，而且还可以指代时间、距离、路程、天气等。如：
It is five o’clock now. 现在五点了。
It is about 1200 kilometres from Beijing to Xi’an. 从北京到西安大约1200公里远。
It is rainy in my hometown in summer. 在我的家乡夏季多雨。
2. it作形式主语
it通常位于句首作形式主语，将真实主语（通常是不定式短语、动名词或主语从句）放在后面，此时it无词义。
it作形式主语的常见句型有：
（1）It+be+形容词+（for／of sb.+）to do sth. 如：
It is necessary for us to plant trees. 对我们来说植树是必需的。
（2）It+be+名词词组+doing／that从句. 如：
It is a pity that you didn’t go to see the film yesterday. 你昨天没看成那部电影真遗憾。
（3）It+be+过去分词+that… 如：
It is reported that there will be a shower tomorrow.
据报道明天将会有一场雷阵雨。
【总结】常用于该句型的动词有：say，hope，think，suppose，expect，report，know，believe，decide等。
（4）It+seems／appears／happens 等不及物动词+that… 如：
It seems that he enjoys pop songs very much. 似乎他非常喜欢流行歌曲。
（5）It+takes+(sb.+) some time+to do sth. 做某事花费（某人）多长时间。如：
It took me an hour to read the reading materials.
花了一个小时才读完那段阅读材料。
3. it作形式宾语
当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾。此时it仍只起引导作用，本身无词义。如：
I found it hard to learn English well. 我发现学好英语是困难的。
【注意】常跟it作形式宾语的动词有：think，make，find，consider，feel，suppose等。

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest in pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.
All polluted air from cars, planes and factories is so thick that it is like a quilt over a city. This kind of quilt is called smog.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn’t blow dirty smoke into the air.
We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution. Rules are not enough. Every person must help to fight pollution.
