Replace the blood as quickly as possible by giving you a transfusion of blood donated by another person. But the doctor

25、cant use just anyones blood. The donors blood has to be of a type that wont be destroyed by your 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 ant

26、igens (special proteins) on their surfaces“A“ antigens and/or “B“ antigens. If your red ceils 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 re

27、d blood cells with two kinds of blood serum. One contains anti-A antibodies. The other kind 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 happe

28、n to your red blood cells. Certain mixtures may make your red cells clump together. By finding 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

29、you have an infection, especially a serious one, the number of white blood cells soars. 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

30、cells in a small marked-off area If the number is much higher than it ought to be, the 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 b

31、lood. The information hidden in a drop of blood may lead a doctor to suggest ways to treat, 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!（分数：5.00）(1).The passage is mainly about _.（分数

32、：1.00）A.discussing the blood testing and its use of determining blood group and checking for infectionB.differentiating the four blood typesC.the technique and procedure of blood testingD.illustrating various types of blood(2).If two persons blood types are different, that means they have different

33、_.（分数：1.00）A.red cells in the bloodB.proteins on the red cells surfacesC.parts of the blood other than the red cellsD.white cells in the blood(3).Which is true when you have an infection?（分数：1.00）A.The number of red blood cells decreases.B.The total number of blood cells remains the same.C.The numbe

34、r of white blood cells increases.D.The total number of blood cells changes.(4).The authors attitude towards blood testing is _.（分数：1.00）A.positiveB.disinterestedC.indifferentD.disapproval(5).According to the passage, what is the relationship between blood testing and keeping healthy?（分数：1.00）A.The i

35、nformation hidden in a drop of blood call keep one healthy.B.To take 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.BText 2/BBiotechnologists have developed genetically modified rice that is for

36、tified with beta carotene which the body converts into vitamin A 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

37、 and crop viruses, bacteria or fungi. Damage caused by pests is incredible. 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 mas

38、sive failure in staple crops in developing countries. Two years ago 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

39、amount of land under cultivation. Biotech can also help solve the 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

40、 crop productivity in developing countries as much as 25% and help 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 g

41、enetically modified crops available will not reduce hunger if farmers 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 e

42、nough food to feed everyone Ubut much of it is simply in the wrong place./U 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 biotec

43、h companies in the rich countries carry out much of the leading-edge 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 fi

44、nancial incentive to target rich markets first in order to help them 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

45、for better collaboration between government agencies both local and in developed countries and private biotech firms.Biotech is not a Upanacea/U, 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 cou

46、ld suffer for years to come.（分数：5.00）(1).According to the first paragraph, what is the function of biotech?（分数：1.00）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 t

47、he challenge of distributing food in developing countries.D.It can help prevent the loss of those crops before they are harvested.(2).By saying “but much of it is simply in the wrong place“ (Lines 56, Para 2), the author means _.（分数：1.00）A.the food is produced mainly in developed countriesB.the food is produced in the place where it is not so ne
