1、用it句型改写句子，意思不变。
1. Giving up smoking is difficult. 2. It idsifficult to give up smoking. 3. 2. Some young people think they look attractive when
they smoke. It seems that some young people think they look attractive when they smoke. 3. Most people believe smoking causes cancer. It is believed that smoking causes cancer 4.Don’t try to quit on a stressful day. It is no use trying to quit on a stressful day.
As you know, if you do the same thing over and over again, you begin to do it automatically.

the thing

5. China produces one third of the world’s cigarettes. It is astonishing that China produces one third of the world’s cigarettes.
6. You are not allowed to advertise cigarettes in this country. It is illegal to advertise cigarettes in this country.

另外，用于该句型的动词还有order, command, suggest, propose, advise, demand, require. request等表示“请 求，建议，命令”等词。此时that 后的从句要用虚拟语气 （should + 动词原形），should 可以省。如： It is suggested that the meeting (should) be put off. It was ordered that the project be completed by the end of this year.
判定强调句型的方法： 将itis/was和that去掉后，剩余
的部分仍然是一个完整的有意义 的句子。
