China has a very large population, and about one fifth of the people in the world live in China. Because of the large population, there was less living space for each family. And what was worse, it was difficult for lots of people to find jobs.At the same time, the large population caused many other difficulties for the whole nation. For example, it was hard for China to supply water and energy to satisfy people's daily needs. Many cities are more crowded and the traffic is much heavier, too. The large population has been a serious problem.
So far, our government has taken many measures to solve the problem.And they worked well. Thanks to the efforts of our government, China is developing quickly and people's living conditions are improving rapidly. The natural environmrnt is becoming better and better. However, We still have a long way to go.

Write a short passage of three paragraphs based on 3a.
One possible version:
China has a very large population in the world. It caused many problems. Everyone should do something to solve them.
First, the government should take many measures to solve the problem, and practice the reform and opening-up to develop our economy. Only in this way can we get more jobs and improve our living conditions.
Second, the energy and water is becoming less and less. We’d better save them as much as possible, and try to find more new energy. In order to solve the problem of heavy traffic, we call on everyone to take a bus or walk as often as possible.
