Dear editor．
I agree with you that everyone should pay more attention to our city environment.
However, some people are still doing things that harm the environment, such as spitting, dropping litter or walking across the street when the traffic lights are red. So it's time for us to do something useful to keep our city clean and tidy.
As a student, we should obey all kinds of the social rules. When we wait for a bus, we should wait in a line. When we meet the people who need help, we should help them at once. We should keep our classroom and our school clean.
If everyone tries their best to protect the environment, our city will become more and more beautiful!
Best wishes!

浙大优学小学年级衔接捷径浙江大学出版社系列答案阅读下列短文，根据短文中的信息完成文后表格。（每空一词）
In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.
