　　The world we live in is becoming more and more intolerable because of environmental destruction. For example , forest destruction results in decrease of planting land and unpleasant weather. In addition, man is faced with problems of water pollution and air pollution.

　　A lot of measures have been taken. Planting trees helps improve and beautify the environment. Besides, laws concerning environmental protection have been put into effect and achieved good results.

　　However, the problem of environmental protection remains far from being solved. On the one hand, the environment pollution and destruction are getting worse and worse in the modern world. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. In a word, there is a long way to go before we enjoy a clean and comfortable world.

　　2、The Problems of Plastic Bags
　　
　　参考范文：
Plastic bags have found their way into a wide area of everyday life. They are applied in big supermarkets, ordinary shops, small stores and street markets. People put in plastic bags everything they buy. They no longer need to carry cloth bags, leather bags or basket bags with them when go shopping. Obviously it is very convenient for plastic bags to be used in people’s everyday life. They are also very cheap. They are usually offered free of charge.

However, plastic bags also bring us side effects. Some people throw away plastic bags causally. This causes the white pollution to our environment , which is very harmful because plastic bags can not disappear by natural decomposition. This is certainly not beneficial to our future.

People have to be careful with the use of plastic bags. They should make sure they put the sued plastic bags into the dustbin when they want to dispose of them. It also might be better for people to use the traditional cloth bags to hold the goods they buy instead of using plastic bags.

　　3、How to Solve the Energy Shortage　如何解决能源短缺问题
　　
　　参考范文：
Energy shortage is a very serious problem in the world. Many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. This, most people agree, will cause serious problems and even crisis and jeopardize the survival of mankind .

　　On the one hand, most people agree that the problem can be solved in one way or another. One is to conserve and save our energy. Energy refers not only to coal, oil, or natural gases but also to goods, land and water, etc. Most countries have realized the wastefulness in their using of energy. They are trying to conserve energy. For example, some countries have a daylight saving system to use less electricity for lighting. Some cities have enforced water savers at public such as restrooms and bars. Some have enforced serious penalties on overuse of electricity, water, and farming land. By these means, people hope the drain on energy resources could be slowed down.

　　However, conservation alone cannot solve the problem. Another way, perhaps the best I think,, is to develop new energy resources. Obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. I think there are many energy resources that we can develop and utilize. We don’t have to depend only on the current conventional energy resources. There are many other energy resources that we can develop such as nuclear power, waterpower and solar power. These resources, if developed, can completely replace the conventional energy and thus solve the problem of energy shortage.
