8、sts are planning to use human immunodeficiency (免疫缺陷) virus (HIV), one of mankinds most feared viruses, as a carrier of genes which can fight cancer and a range of diseases that cannot be cured. The experts say HIV has an almost perfect ability to avoid the bodys immune (免疫的) defenses, making it ide

9、al for carrying replacement genes into patients bodies, according to the Observer.A team at the California-based Salk Institute, one of the worlds leading research centers on biological sciences, has created a special new breed of HIV and has started negotiations with the US Food and Drug Administra

10、tion (FDA) to begin clinical gene therapy (治疗) trials this year. The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have “far wider applications“.The plan remains very lik

11、ely to cause controversy since it involves making use of a virus which has caused more than 22 million deaths around the world in the past two decades. Verma said that the idea of using HIV for a beneficial purpose was “shocking“ but the fierce nature of HIV had disappeared by having all six of the

12、potentially deadly genes removed.Illnesses such as various cancers are caused when a gene in a patients body fails to work properly. In the past two years, breakthroughs in genetics (遗传学) have led gene therapy scientists to try and replace the genes that do not function normally.Unfortunately, the b

13、odys immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier.The HIV virus has the ability to escape from, and then destroy, the immune defense ceils de

14、signed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients bodies.（分数：7.00）(1).FDA has approved the plan of using HIV to cure cancer in humans.A. Right B. Wrong C. Not mentioned（分数：1.00）A.B.C.(2).The idea of using HIV for a

15、beneficial purpose has been widely accepted.A. Right B. Wrong C. Not mentioned（分数：1.00）A.B.C.(3).HIV can be safely used to cure cancer only il the deadly genes have been removed.A. Right B.

More efforts are being made toward environmentally safe work places. An environmental policy research organization has don

18、e that in Washington, D.C. The World Resources Institute re-designed its office to make it safer for people and the environment. This newly-designed office is called a “green“ office.2. The newly designed office was made with environmentally safe building materials instead of building products that

19、are harmful to the environment. For example, the floor of the office is made of bark(树皮)from a cork tree. The bark of a cork tree will renew itself so the tree does not die. The cork floor also feels good to stand on.3. The floor in another part of the office is made of bamboo(竹子). Bamboo is a fast-

20、growing grass that quickly replaces itself. Other areas of the floor are covered with carpeting. However, unlike many offices, the carpet was made without harmful chemicals.4. Storage areas in the office are made from the crushed shells of sunflower seeds. The office doors are made from pressed whea

21、t straw. Wheat straw is an agriculture waste product that would normally be burned. That process adds chemicals to the atmosphere.5. World Resources Institute officials also chose lighting and other electrical equipment that use less energy. And, they improved their communication systems. New video

22、communication equipment lets workers see and talk to people in other cities. The new equipment was added to reduce the amount of travel by office workers. That reduces the amount of harmful gases that are released into the atmosphere by cars or planes.6. The organizations officials also announced a

23、plan that would reduce harmful carbon dioxide gases from their office by the year 2005.7. World Resources Institute officials say the cost of building a “green“ office is similar to that of a traditional office. They say building more “green“ offices could lead to a healthier environment. They say a

24、 healthy environment and a strong economy can exist together. The organization says it is creating a work environment that is better for people.（分数：8.00）(1).Para 1 _.（分数：1.00）填空项 1:_(2).Para 2 _.（分数：1.00）填空项 1:_(3).Para 6 _.（分数：1.00）填空项 1:_(4).Para 7 _.A.

27、 beware. Having a quick “pick-me-up“ cup of coffee1 late in the day will play havoc with your sleep. As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep.Melatonin levels normally start to rise about two hours before bedtime. Level

28、s then peak between 2 a.m. and 4 a. m. , before falling again. “Its the neurohormone that controls our sleep and tells our body when to sleep and when to wake,“ says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have

29、 found that caffeinated coffee halves the bodys levels of this sleep hormone.Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decal. On average, subjects slept

30、336 minutes per night after drinking caffeinated coffee, compared with 415 minutes after decal. They also took half an hour to drop off-twice as long as usual-and jigged around in bed twice as much.In the second phase of the experiment, the researchers wolfe the volunteers every three hours and aske

31、d them to give a urine sample. Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decal drinkers. In a paper accepted for publication in Sleep Medicinc, the researchers suggest that caffeine blo

32、cks production of the enzyme that drives melatonin production.Because it can take many hours to eliminate caffeine from the body, Ohayon recommends that coffee lovers switch to decal after lunch.（分数：1.00）(1).The author mentions “pick-me-up“ to indicate that_.A. melatonin levels need to be raisedB. n

33、eurohormone can wake us upC. coffee is a stimulantD. decal is a caffeinated coffee（分数：0.20）A.B.C.D.(2).Which of the following tells us how caffeine affects sleep?_A.

34、people from sleeping.C. Caffeine halves the bodys levels of sleep hormone.D. Caffeine stays in the body for many hours.（分数：0.20）A.B.C.D.(3).What does paragraph 3 mainly discuss?A. Different effects of caffeinated coffee and decaf on sleep.B. Different findings of Lotan Shilo and a team about caffein

35、e.C. The fact that the subjects slept 415 minutes per night after drinking decaf.D. The evidence that the subjects took half an hour to fall asleep.（分数：0.20）A.B.C.D.(4).What does the experiment mentioned in paragraph 4 prove?_A. There are more enzymes in decaf drinkers urine sample.B. There are more

36、 melatonin concentrations in caffeine drinkers urine sample.C. Decaf drinkers produce less melatonin.D. Caffeine drinkers produce less sleep hormone.（分数：0.20）A.B.C.D.(5).The author of this passage probably agrees that_.A. coffee lovers sleep less than those who do not drink coffeeB. we should not dr

37、ink coffee after supperC. people sleep more soundly at midnight than at 3 a. m.D. if we feel sleepy at night, we should go to bed immediately（分数：0.20）A.B.C.D.16.She was _ the people who worked there.A. criticized byB. disliked byC. popular withD. kept away from（分数：15.00）A.B.C.D.六、第二篇(总题数：1，分数：15.00)
