How to Solve the Social Problems
　　The population problem in the world is becoming more and more serious.It can cause some social problems, such as the narrow living space, missing jobs, lack of water and energy and heavy traffic.In order to solve these problems, I would like to share some ideas with you.
We can try our best to find other suitable places to live in, such as living on the small islands and living under the earth.As for the missing jobs, I think the government can ask old people to give up working in an earlier time to make room for young people.We should develop a good habit of saving every drop of water and try to find some other new energy to take the place of present energy.Besides, we can build more subways and high speed roads to solve the heavy traffic problem.
If everything is solved, our living conditions will become better and better.

[命题点一]It is+adj.for sb.to do sth.的用法 　
●And what was worse, it was difficult for lots of people to find jobs.并且更糟糕的是,对于很多人来说很难找到工作。
◎观察思考:1.It is hard for China to supply water and energy to satisfy people's daily needs.对于中国来说,提供水和能源来满足人们的日常需要是很难的。
2.It's not easy for her to go back to school.对她来说,返回学校不容易了。
3.To make more money is a little hard for him because he is very old now.对他来说赚更多的钱有点困难了,因为他现在太老了。
◎用法总结:1.It is+adj.for sb.to do sth.对某人来说,做某事是……的。It是形式主语,真正的主语是to do sth.。当主语过长,句子失去平衡时,常常用it做形式主语,真正的主语不定式短语放最后。
2.It is+adj.for sb.to do sth.=To do sth.+is+adj.for sb.非谓语动词中的不定式短语做真正主语。
