16、numbered spaces with ONE suitable word. Write your answers on ANSWER SHEET 1. 31 The autumn rains had come in with two angry storms, and Lazy River was waking up. In a week school (31) be closed for Easter vacation. Dick and Turkey planned to have a trip to the inland by boat, (32) they collected ma

17、ps and statistics of the entire inland river system. Water levels down Lazy River; levels down the Namoi; along the Darling and the Murray; all were (33) their fingertips. They were very happy because now (34), it appeared, except the joy of voyaging lay (35) them and the Southern Ocean or Central Q

18、ueensland. It was clear to them (36) Australias early explorers had (37) a big mistake toiling overland when they (38) have opened up the continent rapidly and pleasantly with paddle and pole. It was at this stage (39) Dicks father put his foot down. “Now listen, you chap“, he said quietly. “It begi

19、ns to look like a wet autumn and the river is already (40) wild. A few days rain or a wicked storm or two (41) it 11 flood. Im not going to (42) your mother worrying herself sick about you, Dick.

21、t their fathers suggestion, he became suddenly cheerful. “Thats (50) my dad said“, he grinned. “Now he might let me go with you. He reckons you made a decent swimmer of me!“ Part A Directions: Read the following texts and answer the questions which accompany them by choosing A, B, C or D. Mark your

22、answers on ANSWER SHEET 1. 51 Suppose you lost a lot of blood, what would a doctor do? Replace the blood as quickly as possible by giving you a transfusion of blood donated by another person. But the doctor cant use just anyones blood. The donors blood has to be of a type that wont be destroyed by y

23、our blood. Blood type? Whats that? To find your blood type, the doctor sends your blood to a laboratory. There your red cells are separated from the other parts of your blood. These ceils may have certain antigens (special proteins) on their surfaces “A“ antigens and/or “B“ antigens. If your red cei

24、ls have “A“ antigens you are Type A; “B“ antigens make you Type B; both “A“ and “B“ make you Type AB; neither “A“ nor “B antigens makes you Type O. How do you find these antigens? A lab technician mixes your red blood cells with two kinds of blood serum. One contains anti-A antibodies. The other kin

25、d contains anti-B antibodies. An antibody is a substance that “attacks“ a particular antigen, in this case “A“ or “B“ antigens. The technician then looks at each mixture under a microscope to see what will happen to your red blood cells. Certain mixtures may make your red cells clump together. By fi

26、nding which mixtures do this and which do not, the technician can figure out your blood type. But blood typing isnt the only reason to have a blood test taken. It can also check for signs of infection. How? When you have an infection, especially a serious one, the number of white blood cells soars.

27、This is normal response of your body to an invasion of germs. This time a sample of blood goes to the lab for a CBC complete blood count. A technician will examine your blood under a microscope counting the white cells in a small marked-off area If the number is much higher than it ought to be, the

28、doctor may need to treat you to be sure the infection doesnt spread. Other blood tests can determine the concentration of various chemicals in your blood or the variety and types of blood cells circulating in the blood. The information hidden in a drop of blood may lead a doctor to suggest ways to t

29、reat, or avoid dangerous health conditions. Was the stick in the finger or arm necessary? If protecting yourself from danger is necessary, the answer has got to be.yes! 51 The passage is mainly about _. （ A） discussing the blood testing and its use of determining blood group and checking for infecti

30、on （ B） differentiating the four blood types （ C） the technique and procedure of blood testing （ D） illustrating various types of blood 52 If two persons blood types are different, that means they have different _. （ A） red cells in the blood （ B） proteins on the red cells surfaces （ C） parts of the

31、 blood other than the red cells （ D） white cells in the blood 53 Which is true when you have an infection? （ A） The number of red blood cells decreases. （ B） The total number of blood cells remains the same. （ C） The number of white blood cells increases. （ D） The total number of blood cells changes

32、. 54 The authors attitude towards blood testing is _. （ A） positive （ B） disinterested （ C） indifferent （ D） disapproval 55 According to the passage, what is the relationship between blood testing and keeping healthy? （ A） The information hidden in a drop of blood call keep one healthy. （ B） To take

33、 blood testing is necessary for keeping healthy. （ C） Blood testing can only avoid dangerous health conditions. （ D） Blood testing is necessary only for the sick. 56 Biotechnologists have developed genetically modified rice that is fortified with beta carotene which the body converts into vitamin A

34、and additional iron, and they are working on three kinds of nutritionally in proved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to pests, drought, poor soil and crop viruses, bacteria or fungi. Damage caused by pests is i

35、ncredible. In trials of pest-resistant cotton in Africa yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects as well as bad appear unfounded. Viruses often cause massive failure in staple crops in developing countries. Two years a

36、go Africa lost more than half its cassava crop a key source of calories to the mosaic virus. Genetically modified, virus resistant crops can re duce that damage, as can drought-tolerant seeds in regions where water shortage limits the amount of land under cultivation. Biotech can also help solve the

37、 problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and hel

38、p prevent the loss of those crops after they are harvested. Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role. Making genetically modified crops available will not reduce hunger if fa

39、rmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce. Nor can biotech overcome the challenge of distributing food in developing countries. Taken as a whole, the world produces enough food to feed everyone but much of it is simply in the wron

40、g place. Especially in countries with undeveloped transport infrastructures, geography restricts food availability as dramatically as genetics promises to improve it. Biotech has its own “distribution“ problems. Private-sector biotech companies in the rich countries carry out much of the leading-edg

41、e research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products wont even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help the

42、m rapidly recoup the high costs of product development. But some of these companies are responding to the needs of poor countries. To increase the impact of genetic research on the food production of those countries, there is a need for better collaboration between government agencies both local and

43、 in developed countries and private biotech firms. Biotech is not a panacea, but it does promise to transform agriculture in many developing countries. If that promise is not fulfilled, the real losers will be their people, who could suffer for years to come. 56 According to the first paragraph, wha

44、t is the function of biotech? （ A） The genetically modified, pest-resistant crops might kill good insects as well as bad ones. （ B） It can help solve the problem of soil that contains little aluminum. （ C） It could overcome the challenge of distributing food in developing countries. （ D） It can help

45、 prevent the loss of those crops before they are harvested. 57 By saying “but much of it is simply in the wrong place“ (Lines 5 6, Para 2), the author means _. （ A） the food is produced mainly in developed countries （ B） the food is produced in the place where it is not so needed （ C） the food is pr

46、oduced in the remote area that is hard to be transported （ D） most of the food can reach the regions where they are most needed 58 The problem of biotech is that _. （ A） it cant solve all the problems existed in developing countries （ B） the genetically modified crops in the rich countries are never

47、 responding to the needs of poor countries （ C） it brings devastating effects along with advantages （ D） it cant overcome the challenge of distributing food in developing countries 59 The synonym of “panacea“ in the last paragraph is _. （ A） sole solution （ B） the whole answer （ C） useless （ D） real

48、ity 60 We can learn from the text that _. （ A） biotech is the only solution to lack of food （ B） biotech is still very hard to be used by the poor farmers in the developing world （ C） biotech is more crucial to wealthy countries than developing countries （ D） the risks of biotech outweigh the benefi

49、ts 61 Large, multinational corporations may be the companies whose ups and downs seize headlines. But to a far greater extent than most Americans realize, the economys vitality depends on the fortunes of tiny shops and restaurants, neighborhood services and factories. Small businesses, defined as those with fewer than 100 workers, now employ nearly 60 percent of the work force and are expected to generate half of all new jobs between now and the year 2000. Some 1.2 million small firms have opened their doors over
