     The world is not only hungry, but it is also thirsty for water. This may seem strange to you , since nearly 70% of the earth’s surface (表面）is covered with water . But about 97% of that is sea water, or salt water. Man can only drink and use the other 3% — the fresh water (淡水)from rivers , lakes , underground , and other sources . And we can not even use all of that. Even worse, some of it has been made dirty.

　　 However, as things stand today, this fresh water is still enough for us . But our need for water is becoming larger and larger quickly — almost day by day . We should take steps to do with this problem now and in this way we can get away from a serious world-wide water shortage（缺少）later on .

　   We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways of reusing  it .Today in most large cities , water is used only once and then sent out into a sewer system（下水道）. From there it returns to sea or runs into underground places.

　　 But even if every large city reused its water, we still would not have enough. All we’d have to do to make use of sea water in the world is to remove (去掉) the salt . If we take these steps we’ll be in no danger of drying up.

36. The world is thirsty for water because _________.

　A. man hasn’t got enough food to eat                    B. we haven’t got enough fresh water

　C. only 70% of the earth’s surface is water            D. little water is sent into sewer systems

37. The best but the most difficult way to solve the water problem of the world is to _______ .

　A. remove the salt from sea water                         B. make the water in cities clean

　C. take water from underground                           D. make the need for water smaller

38. What’s the best title（标题）for this passage ?

　A. The Importance of the Water                                   B. The World’s Water Problem

　C. The Thirsty World                                           D. Fresh Water and Sea Water

I don’t like _____ you speak to her.

　　Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away - straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.

　　Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color - coded map showing where plants were running“ fevers”. Farmers could then spot - spray, using 50 to 70 percent less pesticide than they otherwise would.

　　The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.

　56．Plants will emit an increased amount of heat when they are________.

　　A. sprayed with pesticides     B. facing an infrared scanner

　　C. in poor physical condition   D. exposed to excessive sun rays

　57．In order to apply pesticide spraying precisely, we can use infrared scanning to________.

　　A. estimate the damage to the crops    B. measure the size of the affected area

　　C. draw a color -coded map          D. locate the problem area

　58．Farmers can save a considerable amount of pesticide by________.

　　A. resorting to spot – spraying   B. consulting infrared scanning experts

　　C. transforming poisoned rain    D. detecting crop problems at an early stage

　59．The application of infrared scanning technology to agriculture met with some difficulties________.,

　　A. the lack of official support        B. its high cost

　　C. the lack of financial support      D. its failure to help increase production

　60．Infrared scanning technology may be brought back into operation because of________.

　　A. the desire of farmers to improve the quality of their produce

　　B. growing concern about the excessive use of pesticides on crops

　　C. the forceful promotion by the Department of Agriculture

　　D. full support from agricultural experts
