20的英语作文（1）
There have been many changes ,both technological and cultural, in the twentieth century. I believe that one stands out above the rest :advances in medical science. The changes in medical science go together with the changes in technological and cultural areas. One can move ahead only with the help of the others. We can see the results of medical advances in three areas: development of vaccines and antibiotics, expanded access to health care , and improved surgical techniques.
When medical researchers learned how to prevent disease and stop it from spreading, the quality of life for many people around the world improved. Today smallpox is a forgotten disease and vaccinations are no longer required. Polio is under control and the vaccine is widely available . The development of penicillin has helped many people recover from serious illness.
Although health care is not universal even in developed countries, it is much better than it used to be. Local clinics, visiting nurses and specially hospitals have all improved the health care for our communities.
If you should be unfortunate and require surgery : you are still lucky to have the surgery today rather than even ten years ago. Now with microscopic and laser surgery, operations are more efficient. You spend less time in the hospital and you recover faster.
I can’t think of any other change that has affected the lives of so many people. Our health is important to all of us. We all are thankful for advances in the area of medical science.

Now more dust storms, epidemic, fatigue life of people ended almost disappeared, all kinds of cancer eating away at the us one after another of the earth's people.
Back to the old people say the water bridge the somebody else, charactizing a fine spring day, how nice. Now you are "small garden path alone wandering" that's impossible.
Have seen such a report: the Japanese popular a kind of "pain pain disease", no root, for passive house got the disease will be walked into the underworld. At that time, Japan was the panic in the medical community, chasing the SuoYuan, chase ever discover Japanese like to eat fish, the fish love to eat garbage pollution, garbage pollution is Japanese poured into Japan into the sea. From this story, we don't speak Japanese, but should get some enlightenment, the deterioration of environment is referred to in a long-term accumulation, is also caused by everyone involved. Blessing is everyone to leave, a curse is everyone leave, this isn't a person. So take good care of the environment, everyone duty, protect the natural, leave the offspring.
Now I am going to call for everybody, we each member of the earth's, let us act now! Good care environment, protect the natural, leave f offspring!
我们要爱护环境，保护大自然。
地球是我们人类唯一赖以生存的地方，是我们的家园。我们不能因为一时利益而将她断送在我们手中。现在的地球危在旦夕，森林少了，小鸟少了，美丽的小桥流水的自然环境不见了，河里喂鱼没有不人工供氧就要翻池了。现在沙尘暴多了，流行病多了，劳累一生的人们颐养天年的几乎不见了，各类的癌症蚕食着我们一个又一个的地球人。
回想老人们说的小桥流水人家、鸟语花香天下，是何等的惬意。现在你要“小园香径独徘徊”那也是不可能了。
曾见到这样一个报道：日本流行了一种“痛痛病”，查无根，找无源，得了该病就要走进阎罗殿。当时日本医学界真是着了慌，追本索源，追到底发现是日本人爱吃鱼，日本鱼爱吃污染垃圾，污染垃圾是日本人倒进日本进海里的。从这个故事中，我们不说日本人该死，而应得到一点儿启示，环境的恶化是人们长期积累所指的，也是人人参与所致的。福是大家留的，祸也是大家留的，这不是一个人的事。所以爱护环境，人人有责，保护自然，留福后代。
现在我要呼吁大家，我们地球上的每一个成员，愿我们立即行动起来吧!爱护环境，保护自然，留福后代!

Now, because of the big cities site random discharge of sewage, and people are constantly littering. Disappeared, the vibrant river became a smelly sewage river, I don't like it!
Nowadays, many wild animals become a plate of food. Without these lovely animals, our life will become special boring. Rose up in the morning, can't hear the birds chirping and crisp sound, that is bad!
Patches of forest became less factories. The lawn into a wasteland, beautiful grassland into desert. Why is this? This is because people caused by deforestation.
Human survival depends on the environment, the environment depends on human protection. Do humans have that moment didn't wake up until the end of the earth? I call on: to protect the environment! We act together.
地球是人类的母亲，人类的生存离不开她。地球受到了破坏，我们又怎么能袖手旁观呢?就说我家西边的小河吧!以前，这条小河清澈见底，有很多小鱼小虾在里面自由自在地游着，整天过着无忧无虑的生活，小河里充满了生机。那时我很喜欢到那里玩。现在，由于大城市的工地随意的排放污水，还有人们不断的乱扔垃圾。那条生机勃勃的小河不见了，变成了一条臭烘烘的污河，我再也不喜欢那里了!
如今，许多野生动物成为了人们盘中的美食。如果没有这些可爱的动物，我们的生活就会变得特别无趣。早晨起来，不能听到小鸟叽叽喳喳清脆的叫声，那多不好啊!
片片森林变成了座座工厂。草地变成了荒原，美丽的草原变成了沙漠。这究竟是为什么?这是因为人们乱砍乱伐造成的。
人类要靠环境生存，环境要靠人类保护。难道人类还要等到地球毁灭的那一刻才醒悟吗?我呼吁：保护环境!大家一起行动吧。
