　　How to Reduce the City Present Population？
　　Our modern city is too crowded， and to solve the problem， three proposals are put forward. Most people believe that we should fist practise the policy “Late Marriage” and “One Couple， One Child” in order to reduce the birth rate. Secondly， the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. Finally more and more people suggest that living blocks with shopping centers， schools， hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. In this way city citizens will be encouraged to move there to live and work. If these three proposals are well carried out， the city population will be greatly reduced.

篇十一：Protecting the Forests

　　Now in some places of our country, a number of people have been cutting down the trees in the forests because they need wood and more farmland. The areas of forests are getting smaller and smaller. Some scientists say that there will be no vast forests in 20 or 30 years. It is really a terrible thing. Where the forests disappear, dust storms will occur occasionally. The weather will get hot and dry. The whole earth will become a big desert. A lot of plants and animals will disappear.Crops will not grow anywhere. Life will be difficult for everyone. The human beings will be punished for their forest-destroying activities.
　　Therefore, we should realize the importance of taking care of our forests. We should do our best to protect our living environment and keep our mountains green,the water clean, and the sky blue.

篇十二：The Importance of Trees

　　As we all know, trees are very useful. They are of great benefit to man as follows: First, trees provide us with wood and other products; Second, their roots can allow the rain to sink in and keep the soil, so they help to prevent droughts and floods. Trees can clean air and beautiful life.
　　Unfortunately, nowadays in many parts of the world lots of people fail to realize the importance of trees. They have cut trees down in large numbers without a plan,which makes the soil washed away. They don't know where there no trees, the rain washed away the surface of the soil and this causes floods.
　　We ought to plant trees each year and carefully look after new trees in order not to make the forest slowly disappear. Only' in this way can we make the forest serve man forever.
