The UN Environment Program and Food and Agriculture Organization (FAO) released （发布）a report with the new findings. The findings are based on information collected in 170 nations during the past ten years. FAO officials say the world has lost about 1,000 kinds of farm animals because of human’s development in the past century. The officials say many other animals are still in danger. They warn that one-third of them are at the risk of disappearing.About two billion people depend at least partly on farm animals to earn money. That is around one third of the world population. FAO officials are concerned about farmers producing enough to feed the world’s growing population. They warn that meat, milk and egg production will need to be increased by more than two times during the next twenty years.FAO officials have gathered information about more than 4,000 kinds of bird andanimal populations. 740 of those animals no longer exist. More than 1,300 other animals are said to be endangered or at the high risk of extinction(灭绝). Many of them are very important farm animals. For example, in Madagascar, Renitelo cattle have almost disappeared. In the Philippines, the Banaba chicken is now rare.The report warns that more than 2,000 other animals could disappear within the next twenty years unless action is taken. It says that the greatest threat （威胁）is the export of animals from industrial countries to developing ones. This can lead to replacement of some native animals. As a matter of fact, animals from industrial nations often are considered more productive in developing countries. However, these animals are best for the environment of the areas they come from. They may have a difficult time surviving under extreme conditions. The FAO says having different kinds of animals is a way to protect against loss of animals from bad weather conditions or the spread of diseases. The UN agency is starting a five-year project to help countries better understand the issue.31. What can we learn from the FAO’s findings?A. Human activities have a great influence on animals.B. About 1,000 farm animals are out of control now.C. 170 nations should be responsible for extinct animals.D. Agriculture can’t de velop well because many animals are in danger.32. What will happen if animals continue disappearing?A. More and more people will starve.B. Some people will lack economic resources.C. Farm animals will be people’s enemies.D. A large population will lose their jobs.33. What does the export of animals bring about?A. Exported animals provide productive foods.B. Exported animals create chances for industry.C. Exported animals die from bad conditions.D. Exported animals might leave no space for native ones.34. The text is written mainly ___________.A. to let people know how to raise native animalsB. to call on people to protect exported C. to discover the reasons why animals disappearD. to show people the seriousness of animal extinction参考答案一．单词1. debated2. atmosphere3. flows4. obvious5. beneficial6. environmental7. taxes8. preserve9. approached 10.ridiculous二. 词组11. running out of 12. wipe out13.am concerned about 14. cutting back on15.

The ation is putting much pressure on the world’s supply of water.With 97% of the world’s water too salty to be drunk or used in agriculture，the worldwide supply of water needs careful management，especially in agriculture.Although the idea of a water shortage seems strange to someone fortunate enough to live in a high rainfall country，many of the world’s agricultural industries experience constant water shortages.
Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves.Because there is no rainfall in these areas，such reserves can only decrease，and it is believed that fifty years of pumping will see them run dry.

SThe Cause and the Effect of the HazeWith the deterioration (恶化) of air quality, the phenomenon of haze (雾霾) appears more and more. Recently the haze in many regions is merged into mist as a severe weather warning forecast together, which was referre d as “haze weather”. There are several causes for the haze.The main cause is that the atmospheric pressure is low and the air circulation is not smooth. As a result, the tiny particles (颗粒) in the air are gathered, floating in the air. Second, the dust is too much on the ground and the humidity (湿度) of the air is low, so it is easy for the dust to be stirred up. Automobile exhaust (汽车尾气) is the main pollutant (污染物). In recent years, a great number of city cars appear in the street. Accordingly, the more cars make the more pollution, which also caused the haze. Additionally, the factories also produce the pollution. The haze often appears in winter, because winter heating lets out the pollutants into the air.Out of question, the haze has bad effects on people's health. It is reported that some people have coughs or headaches because of the haze. The doctors say, “the haze will harm people's respiratory system (呼吸系统), even lead to death.”On the environment, the haze causes the decrease of the atmospheric visibility (能见度), which has blocked traffic. In a word,the haze makes the people's life inconvenient.Section ⅠWelcome to the unit & Reading — Pre-readingThe economy①or the environment —must we choose?TV host②：James LongSpeakers: Lin Shuiqing, a spokeswoman③fromthe Green SocietyQian Liwei, a business development consultant④James Long：Good morning.Today's debate⑤question is，‘The economy or the environment —must we choose？’With me are Ms Lin Shuiqing⑥，from the Green Society, and Mr Qian Liwei，a business development consultant.We are following our usual schedule⑦for debates.Ms Lin Shuiqing will speak first for three minutes.Mr Qian Liwei will follow, also for three minutes.Then we will open the floor⑧for discussion.If you have any questions or comments, you can use this time to express⑨them. ①economy[I'kɒnəmI]n．经济(情况)；经济体②TV host电视节目主持人③spokeswoman['spəʊkswʊmən]n．女发言人spokesman n．发言人④consultant[kən'sʌltənt]n．顾问⑤debate[dI'beIt]n．&v i.辩论；争论，讨论⑥表语with me提前，构成完全倒装句。

我今天首先要谈的是化学废物如何破坏世界上的大片区域的。
许多地方已经被毁，许多动植物已经死亡。
这很可怕。
工厂生产大量有害化学物质。
它们产生的废物进入大气，使我们生病。
其他种类的废物流入水中，杀死河流及海洋生物。
捕鱼船也在毁灭大量的海洋生物。
这些船捕捞大量的鱼，而不给它们时间产卵。
这将导致今后我们食用的鱼的数目更小。
一方面我们在毁灭环境，另一方面我们继续生育越来越多的人口，这些人口需要更多的土地居住，也需要更多的食物食用！与1800年相比，世界人口的数量已经增长了六倍。
现在约有七十亿人！It is our duty○29to try to cut back on○30○29duty['djuːtI]n．责任，义务，本分production○31and reduce the number of○32 things we make and buy○33.The amount of rubbish we produce○34is turning into○35 a big problem；we need to think more about recycling○36our waste.It would be good to increase the amount of waste we recycle○37，and teach people ways of living that do not harm the environment○38.We may even create more jobs and help our country become more developed at the same time.Thank you.
