三、It作形式主语及形式宾语题(这也是一个常考点，it本身是没有意思的，注意it还可以指时间，天气等。)

　　1、It is difficult to study English well.

　　2、We think it is important to pass the exam.

四、强调句型(大家要记住的是it is (was)……。that…。，如果前面是it iswas 后面往往选用that，当然强调人的时候也可用who)

　　1、It was at an evening party that I first saw her.

　　2、It is what you will do that is important.

　　3、When was it that he bought a new car

五、倒装句型

　　全部倒装句(这种全部倒装题历年只考过一次，考得最多的都是下面的部分倒装)

　　1、Stop talking! There comes the teacher.

　　部分倒装句(如果选项里面有两个主谓倒装了，两个没有，我们一般要在倒装里做选择)

　　1、So badly was he hurt in the accident that he had to be sent to hospital.

　　2、Not only does he study well， but also he is always ready to help others.

　　3、Mary has done well in the English exam. So she has. She always does well in the exam.
