Hi，everyone.Today my topic is about environmental protection.
Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded.
We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.
Pollution has been a serious problem for a certain time around the world. There are many causes for it. Transportation is the main factor of pollution. When the waste gas from cars is released, the air is polluted. People breathing in the polluted air can develop respiratory disease. Another factor is that
people throw their garbage everywhere. All kinds of garbage not only spoil the splendid environment, but also cause environmental pollution. Wastewater from factories is also poured into rivers and this causes water pollution
Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.
Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. We are sure that we can have a better and cleaner place in the future.
OK，we have known that we can prevent pollution if everyone makes the efforts. So，let’s do it now . That's it.Thank you everyone!
. 今天，我们的自然环境质量已经成为一个重要问题。世界人口增长如此之快，世界已变得过于拥挤。
我们正在利用我们的自然资源，同时污染的危险化学品的环境。如果我们继续做这个地球上，生活无法生存。
污染已经成为一定时期内时间范围内的一个严重问题。 原因很多，交通玉树是主要原因，当汽车排出废气时，空气就被污染了，人们呼吸了被污染的空气，会导致呼吸道疾病。 另外一个原因就是人们随处乱扔垃圾，不仅破坏了美观的环境，还污染了环境。工业废水也排入河流，引起水污染。
有关人士取得了一些在环境保护方面的进展。许多国家的政府已建立了法律，保护空气，森林和海洋资源，并停止对环境的污染。
但更应采取措施来解决环境问题。人们应该进一步的教育，认识到问题的重要性，使用现代节育方法，以保护我们的天然资源和循环利用我们的产品。我们相信，我们可以有一个更加美好，更清洁的地方。
This year's summer vacation was most enjoyable. I spent fifteen days helping my grandparents doing farm work in the countryside， where I saw mountains and fields covered with green plants. Sometimes I went swimming in the river to the west of the village， the water in which was quite clear.
I kept a diary every day. Besides doing farm work， I help the children in the neighborhood with their lessons. All of them showed much interest in English. They could read and write well， but they could hardly understand simple English. So every day in the morning I spent about two hours helping them improve their listening and spoken English. They all made great progress. Their parents all thought highly of me. I now realize that knowledge is very much needed in the countrysideThis year's summer vacation was most enjoyable.
