CHEMICAL OR ORGANIC FARMING
Over the past half century，using chemical fertilizers has become very common in farming.
Many farmers welcomed them as a great way to stop crop disease and increase production. Recently，however, scientists have been finding that long term use of these fertilizers can cause damage to the land and，even more dangerous，to people’s health.
What are some of the problems caused by chemical fertilizers First，they damage the land by killing the helpful bacteria and pests as well as the harmful ones.Chemicals also stay in the ground and underground water for a long time.This affects crops and，therefore，animals and humans，
since chemicals get inside the crops and cannot just be washed off.These chemicals in the food supply build up in people’s bodies over time.Many of these chemicals can lead to cancer or other illnesses. In addition，fruit，vegetables and other food grown with chemical fertilizers usually grow too fast to be full of much nutrition.
They may look beautiful，but inside there is usually more water than vitamins and minerals.
With these discoveries，some farmers and many customers are beginning to turn to organic farming. Organic farming is simply farming without using any chemicals.They focus on keeping their soil rich and free of disease.
A healthy soil reduces disease and helps crops grow strong and healthy.Organic farmers，therefore，often prefer using natural waste from animals as fertilizer. They feel that this makes the soil in their fields richer in minerals and so more fertile.This also keeps the air，soil，water and crops free from chemicals.
Organic farmers also use many other methods to keep the soil fertile.They often change the kind of crop in each field every few years，for example，growing corn or wheat and then the next year peas or soybeans.Crops such as peas or soybeans put important minerals back into the soil，
making it ready for crops such as wheat or corn that need rich and fertile soil.Organic farmers also plant crops to use different levels of soil，for example，planting peanuts that use the ground’s surface followed by vegetables that put down deep roots.Some organic farmers prefer planting grass between crops to prevent wind or water from carrying away the soil,
and then leaving it in the ground to become a natural fertilizer for the next year’s crop.These many different organic farming methods have the same goal：to grow good food and avoid damaging the environment or people’s health.
化学耕作还是有机耕作？
在过去的半个世纪里，在耕作中使用化学肥料已经非常普遍。一些农民喜欢使用化肥，把化肥作为防治农作物病虫害和增产的重要手段。然而，最近科学家们发现长期使用这些肥料会对土地造成损害，甚至更危险的是，会对人们的健康造成危害。
化学肥料都能造成哪些问题呢？首先，它们杀死有害细菌和害虫的同时也杀死了有益细菌和益虫，从而对土地造成损害。化学肥料还会在土壤和地下水中保存很长时间。这将会影响农作物，因此影响到动物和人类，因为化学物质会进入到农作物里面，而不能被冲洗掉。食物中的这些化学物质会随着时间的推移而在人体内逐渐堆积.很多化学物质能导致癌症或其他疾病.
另外，使用化学肥料种植的水果、蔬菜和其他食物通常生长过快而缺少足够的营养。它们可能看起来很好，但里面通常含更多的水分而不是维生素和矿物质.
由于这些发现，一些农民和很多消费者开始转向有机耕作。有机耕作就是不使用任何化学肥料的耕作。他们主要是想保持土壤肥沃且免受病害。
健康的土壤能减少病害并促进农作物茁壮生长。因此，有机耕作的农民通常喜欢使用天然的动物粪便作肥料。他们认为这样能使土壤中的矿物质更丰富因而也会更肥沃。这也能使空气、土壤、水和农作物不受化学物质的污染。
有机耕作的农民也使用很多其他的方式保持土壤肥沃。他们经常每隔几年就在一块土地里更换一次农作物，例如，今年种植玉米或小麦，来年改种豌豆或大豆。像豌豆或大豆这样的农作物能使土壤重新富含重要的矿物质，这为种植需要肥沃土壤的农作物，如小麦和玉米等做好了准备。
有机耕作的农民也使用不同的土壤层种植作物，例如，先种植生长在表层土壤的花生，然后种植生根于深层土壤的蔬菜。有些有机耕作的农民喜欢在农作物之间种草来防止水土流失，然后将草留在地里成为来年农作物的天然肥料。这些不同的有机耕作方式有一个相同的目标：种植好粮食并避免损害环境和人们的健康。

A PIONEER FOR ALL PEOPLE
Although he is one of China’s most famous scientists,Yuan Longping considers himself a farmer,for he works the land to do his research.Indeed，his sunburnt face and arms and his slim，
译文助读
strong body are just like those of millions of Chinese farmers,for whom he has struggled for the past five decades.Dr Yuan Longping grows what is called super hybrid rice.In 1974,he became the first agricultural pioneer in the world to grow rice that has a high output.
This special strain of rice makes it possible to produce one third more of the crop in the same fields.Now more than 60% of the rice produced in China each year is from this hybrid strain.
Born in 1930，Dr Yuan graduated from Southwest Agricultural College in 1953.Since then，finding ways to grow more rice has been his life goal. As a young man，he saw the great need for increasing the rice output. At that time，
hunger was a disturbing problem in many parts of the countryside.Dr Yuan searched for a way to increase rice harvests without expanding the area of the fields. In 1950，Chinese farmers could produce only fifty million tons of rice.
In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests mean that 22% of the world’s people are fed from just 7% of the farmland in China.
Dr Yuan is now circulating his knowledge in India，Vietnam and many other less developed countries to increase their rice harvests.Thanks to his research，the UN has more tools in the battle to rid the world of hunger.
Using his hybrid rice，farmers are producing harvests twice as large as before.
Dr Yuan is quite satisfied with his life.However，he doesn’t care about being famous. He feels it gives him less freedom to do his research.
He would much rather keep time for his hobbies.He enjoys listening to violin music，playing mah jong，swimming and reading.Spending money on himself or leading a comfortable life also means very little to him.Indeed，
he believes that a person with too much money has more rather than fewer troubles. He therefore gives millions of yuan to equip others for their research in agriculture.
Just dreaming for things，however，
costs nothing.Long ago Dr Yuan had a dream about rice plants as tall as sorghum.Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut.Dr Yuan awoke from his dream with the hope of producing a kind of rice that could feed more people.
Now，many years later，Dr Yuan has another dream：to export his rice so that it can be grown around the globe. One dream is not always enough，especially for a person who loves and cares for his people.
造福全人类的先驱者
尽管袁隆平是中国最有名的科学家之一，但他仍然认为自己是个农民，因为他在田间耕作，进行科学研究。的确，他晒黑的面庞和手臂，以及清瘦而又结实的身躯，就跟数百万中国农民一模一样，
他过去50年来的努力工作就是为了帮助他们。袁博士种植的是被称为“超级杂交水稻”的稻种。1974年,他成为世界上第一位种植高产水稻的农业先锋。这种特殊的稻种使得同样的田地多收获三分之一的产量。如今中国每年出产的稻米有60%以上出自这种杂交稻种。
袁博士于1930年出生，1953年毕业于西南农学院。从那时起，找到水稻高产的方法便成为了他毕生的目标。年轻时，他就看到了水稻增产的巨大需求。那时，饥饿是许多农村地区面临的困扰。
袁博士开始在不增加土地面积的基础上寻求达到增收的途径。1950年，中国的农民只能生产大约五千万吨稻米,而近来却生产了将近两亿吨。这一粮食产量的增加意味着中国用仅仅7%的耕地养活了世界上22%的人口。
目前袁博士还在印度、越南和其他一些欠发达国家传播提高水稻产量的知识。由于他的研究，联合国在消除世界饥饿的战斗中有了更多的方法。用他的杂交水稻种子，农民们种出的粮食比以前多了一倍。
袁博士很满意自己的生活。但他对成名并不关心。他觉得成名后搞研究就没那么自由了。他宁愿把时间花在自己的爱好上。他喜欢听小提琴演奏曲,玩麻将，游泳和看书。在自己身上花钱或享受舒适的生活对他而言意义不大。
事实上，他认为一个人有了太多的钱,就会有更多而不是更少的烦恼。因此,他资助几百万元供其他人进行农业研究。
做梦是不花本钱的。很久以前,袁博士梦见水稻长得像高粱一样高,稻穗像玉米穗一样大,而每粒稻米都像花生一样饱满。
袁博士从梦中醒来，希望能种植一种能养活更多人的水稻。如今袁博士还有另外一个梦想，那就是出口他的水稻，让它长遍全球。一个梦想总是不够的，尤其是对一个热爱和关心人民的人来说，更是如此。

Yuan Longping’s road to super hybrid rice
袁隆平，中国工程院院士，
我国当代杰出的农业科学家，
享誉世界的“杂交水稻之父”。他工作50多年来所取得的科研成果使我国杂交水稻研究及应用领域领先世界水平，不仅解决了中国粮食自给的难题，也为世界粮食安全做出了杰出贡献。
Yuan Longping was born in a poor farmer’s family in 1930 and graduated from Southwest Agricultural College in 1953.Then he began his teaching career at an agriculture school in Anjiang，Hunan Province.
He came up with an idea of hybridizing rice in the 1960s，when a series of natural disasters and improper policies had plunged (使陷入……) China into a famine (饥荒) that caused many deaths.
Since then，he has devoted himself to the research and development of a better rice breed.In 1964，he happened to find a natural hybrid rice plant that had obvious advantages over others.Greatly encouraged，he began to study the elements of this particular type.In 1973，in cooperation with others，he was able to cultivate (培育) a type of hybrid rice species which had great advantages.
It yielded 20 percent more per unit than that of common ones.The next year their research made a breakthrough in seeding.They successfully developed a set of technologies for producing hybrid rice，putting China in the lead worldwide in rice production.For this achievement，he was named the “Father of Hybrid Rice”．
In 1979，their technique for hybrid rice was introduced into the United States，the first case of intellectual property rights transfer in the history of new China.
At present，as many as 50% of China’s total rice fields grow Yuan Longping’s hybrid rice species，which yield 60% of the rice production in China.
Due to Yuan’ s hard work，China’ s total rice output rose from 50 million tons in 1950 to nearly 200 million tons in recent years.The annual yield is enough to feed 60 million people.
Yuan Longping was named a winner on March 29,2004，of the annual US $250,000 World Food Prize for his work in producing high production rice.
In the same year he got Wolf Prize in agriculture in Israel.He loves playing mah jong and the violin and swimming.He said he would go on working hard at his super hybrid rice project.
Questions：
Read the passage and tell the following sentences true (T) or false (F)．
1．The passage is mainly about how Yuan Longping cultivated hybrid rice successfully.( )
2．Before Yuan devoted himself to the study of hybrid rice，he had worked as a teacher in Hunan Province.( )

He focused on improving the crops’ production.After over one decade，Mexico doubled its wheat production per hectare and exported wheat to other countries. Thanks_to his work，many countries also got rid of hunger.
诺曼·博洛格是著名的“绿色革命之父”。作为一名农业科学家，他使多达10亿的人免受饥饿的侵害。他在世界各地游历，传播自己的方法以帮助贫穷的人们提高他们的作物产量。1970年,他因在与饥饿作斗争中作出的巨大成就而获得了诺贝尔和平奖。
当很小的时候，诺曼宁愿待在自己家的农场里研究作物。他经历过经济大萧
条，那时饥饿是一个严重的问题。因
此，他决心要使人们摆脱饥饿。1940
年，他开始在墨西哥从事一个项目。他注重提高农作物的产量。十年多以后，墨西哥的小麦产量每公顷是以前的两倍,而且小麦还出口到其他国家去。多亏了他的工作，很多国家也摆脱了饥饿。
但是并不是每个人都对他的工作感到满意。环境主义者们批评他的密集型方
法,其中包括化肥的使用。他们说食物中的这些化学成分会在人体中逐渐堆积,一些化学成分能导致癌症或其他疾病。诺曼不在意他们的评论。
但后来，他也要求农民不要过多使用化肥以减少这些潜在的危险。但他从未后悔过自己为世人所做的一切。他同时也强调食品安全的重要性。
