作形式主语或形式宾语
考点 2
考向一
(1)英语中不定式、动名词、主语从句等复杂成分在作主语时主语往往显得很长，使整个句子看上去头重脚轻，这时就借助“it”来作形式上的主语，而把真正的主语移到句子后边去，使全句看上去平衡一些。 “it”没有实际的意义。
eg: It is fun for her to study, but it is difficult for her to study and work at the same time.
对于她来说学习是有趣的，可是边工作边学习对她来说是困难的。
(2)it用作形式主语的重要句型。
①It＋be＋adj.＋for(of) sb. to do sth. 某人做某事……
eg：It is hard for him to make up his mind.
对他来说下决心很难。
It was foolish of her to say that.
她说那样的话，太愚蠢了。
此句型中的介词of和for的区别是：用of时，形容词指某人的性格、特点等。如：nice，kind，silly，wise，clever，careless，rude，polite，brave等。用for时，形容词指事物的性质、特征等。如：difficult，easy，impossible，important，dangerous，fun等。
②It＋ be＋ n．＋ to do sth.做某事是……
eg：It is our duty to protect the environment.
保护环境是我们的责任。
③It takes/took sb.＋时间段＋to do sth.某人做某事花了多少时间。
eg: It took me two hours to do my homework.
我做家庭作业花了两个小时。
It is great ________ us to get so many favourite books on International Children's Book Day.
A．to B．with
C．of D．for
D
考向二
作形式宾语
当不定式、动名词、从句等复杂成分作宾语且后面跟有宾语补足语时，通常会在宾语补足语前使用it作形式宾语，而将真正的宾语移至句末。其基本结构为“动词＋it＋宾语补足语＋不定式(动名词或从句)”，常用于这种结构的词有：think，find，make，consider，feel，believe等。
eg: I find it difficult to do the job well.
我发现做好这项工作很难。
I think it best that you should stay here.
我认为你最好呆在这里。
互联网使得我们相互交流更加便捷。
Internet makes _____ more convenient for us to _____________ with each other.
it
it的用法
小小 it 神通大，既指事物又指人，神通广大当替身；
时间、距离和天气，it 表示最称心。
it 本身无意义，用来代替主或宾；
如果强调主宾状，强调句型派用场。
communicate

How to Protect Our Environment
The environment is becoming worse and worse. It has a great influence on people's health, especially the air pollution. But how can we reduce the pollution to protect the environment?
I think we should begin with the following things. We should pick up the rubbish and throw it into a dustbin, and we should collect waste things like batteries and plastic bags.
What's more, when we go to school or work, we'd better not take a car. It's wise to go on foot or by bike.
It's our duty to keep our environment clean. Let's take action now! If everyone does such useful things, our environment will become much cleaner.
再见
