Choose the best word or phrase for each numbered blank and mark A, B, C or D on ANSWER SHEET 1. 25 Sugar cane was once a wild grass that grew in New Guinea and was used by local peo
18、ple for roofing their houses and fencing their gardens. Gradually a different variety evolved which contained sucrose(蔗糖 )and was chewed on for its sweet taste. Over time, sugar cane became a highly valuable commercial plant, grown throughout the world. 【 B1】 _ Sugar became a vital ingredient in all
19、 kinds of things, from confectionery(糖果点心 )to medicine , and, as the demand for sugar grew, the industry became larger and more profitable.【 B2】 _Many crops withered(枯萎 )and died, despite growers, attempts to save them, and there were fears that the health of the plant would continue to deteriorate.
20、 In the 1960s, scientists working in Barbados looked for ways to make the commercial species stronger and more able to resist disease. They experimented with breeding programmes, mixing genes from the wild species of sugar cane, which tends to be tougher, with genes from the more delicate, commercia
21、l type.【 B3】 _This sugar cane is not yet ready to be sold commercially, but when this happens, it is expected to be incredibly profitable for the industry. 【 B4】 _Brazil, which produces one quarter of the world s sugar, has coordinated an international project under Professor Paulo Arrudo of the Uni
22、versidade Estaudual de Campinas in Sao Paulo. Teams of experts have worked with him to discover more about which parts of the genetic structure of the plant are important for the production of sugar and its overall health. Despite all the research, however, we still do not fully understand how the g
23、enes function in sugar cane.【 B5】 _This gene is particularly exciting because it makes the plant resistant to rust, a disease which probably originated in India, but is now capable of infecting sugar cane across the world. Scientists believe they will eventually be able to grow a plant which cannot
24、be destroyed by rust. AUnfortunately, however, the plant started to become weaker and more prone to disease. BSugar cane was now much vigorous and the supply of sugar is therefore more guaranteed. COne major gene has been identified by Dr Angelique D Hont and her team in Montpe-lier, France. DThe ma
25、jority of the world s sugar now comes from this particular commercial species. ESince the 1960s, scientists have been analysing the mysteries of the sugar cane s genetic code. FThe sugar cane s genetic code has been found by a farmer in 1950. GEventually, a commercial plant was developed which was 5
26、 percent sweeter than before, but also much stronger and less likely to die from disease. 26 【 B1】 27 【 B2】 28 【 B3】 29 【 B4】 30 【 B5】 30 Walking, if you do it vigorously enough, is the overall best exercise for regular physical activity. It requires no equipment, everyone knows how to do it and it
27、carries the【 C1】 _risk of injury. The human body is designed to walk. You can walk in parks or along a river or in your neighborhood. To get【 C2】 _benefit from walking, aim for 45 minutes a day, an average of five days a week. Strength training is another important【 C3】 _of physical activity. Its pu
28、rpose is to build and【 C4】 _bone and muscle mass, both of which shrink with age. In general, you will want to do strength training two or three days a week,【 C5】_recovery days between sessions. Finally, flexibility and balance training are【 C6】 _important as the body ages. Aches and pains are high o
29、n the list of complaints in old age. The result of constant muscle tension and stiffness of joints, many of them are【 C7】 _, and simple flexibility training can【 C8】 _these by making muscles stronger and keeping joints lubricated(润滑 ). Some of this you do whenever you stretch. If you watch dogs and
30、cats, you 11 get an idea of how natural it is. The general【 C9】 _is simple: whenever the baby has been in one position for a while, it is good to【 C10】_stretch it in an opposite position.

32、n an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour s flight, one of the scientists wrote in his book, “Look here for probable metal. “ Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, “Gold poss
33、ible. “ Walking across hilly ground, four scientists reported, “This ground should be searched for metal. “ From an airplane over a hilly wasteland a scientist sent back by radio one word: “ Uranium. “ None of the scientists had X-ray eyes: they had no magic power of looking down below the earth s s
34、urface. They were merely putting to use one of the newest methods of locating minerals in the ground . trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals
35、 deep in the earth may affect the kind of bushes and trees that grow in the surface. At Watson Bar Greek, a brook(小溪 )six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots w
36、ere dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory, the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches, and seeds showed no silver. But there w
37、ere small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunks had more gold than those growing on the ends of the branches. 41 Scientists were flying over a desert or a hilly wasteland or a mountain area in order to search for_i

41、ing_. （ A） X-ray （ B） magic power （ C） a special instrument （ D） trained eyes 45 The most frightening words in the English language are, “ Our computer is down. “ You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in
42、 the ticket office said, “Im sorry, I cant sell you a ticket. Our computer is down. “ “ If your computer is down, just write me out a ticket. “ “I cant write you out a ticket. The computer is the only one allowed to do so. “ I looked down on the computer and every passenger was just standing there d
43、rinking coffee and staring at the black screen. Then I asked her, “What do all you people do?“ “We give the computer the information about your trip, and then it tells us whether you can fly with us or not. “ “So when it goes down, you go down with it. “ “Thats good, sir. “ “How long will the comput
44、er be down?“ I wanted to know. “I have no idea. Sometimes it s down for 10 minutes, sometimes for two hours. There s no way we can find out without asking the computer, and since it s down it wont answer us. “ After the girl told me they had no backup computer, I said. “Let s forget the computer. Wh
45、at about your planes? They re still flying, aren t they?“ “I couldn t tell without asking the computer. “ “Maybe I could just go to the gate and ask the pilot if he s flying to Washington, “ I suggested. “I wouldn t know what gate to send you to. Even if the pilot was going to Washington, he couldn
46、t take you if you didn t have a ticket. “ “Is there any other airline flying to Washington within the next few hours?“ “I wouldnt know, “ she said, pointing at the dark screen. “Only IT knows. It cant tell me.“ By this time there were quite a few people standing in lines. The word soon spread to oth
47、er travelers that the computer was down. Some people went white; some people started to cry and still others kicked their luggage. 46 The best title for the article is_. （ A） When the Computer Is Down （ B） The Most Frightening Words （ C） The Computer of the Airport （ D） Asking the Computer 47 What c
