I was looking forward to having five days off from duty. Unfortunately, the only one train a day back to my home in Syd

9、ney had already left. So I thought Id hitch a ride (搭便车). I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldnt give me a lift, I should come back to his house for lunch. He noticed

10、 me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured (使放心) me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home. Tw

11、enty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favour Id been given decades earlier. I pulled over and picked him up. I made him comforta

12、ble on the back seat and offered him some water. After a few moments of small talk, the man said to me, “You havent changed a bit, even your red hair is still the same.” I couldnt remember where Id met him. He then told me he was the man who had given me lunch and helped me find a lift all those yea

B.Those who give rides will be repaid.C.Good manners bring about happiness. D.People should offer free rides to others.3、It happens every spri

16、ng. Flowers suddenly burst out everywhere on the same day. But how exactly do plants “know” when to flower?It is a question that has puzzled biologists for years. But according to Science Daily, a US research group may have finally answered it-the secret lies in a protein called FKF1 which allows pl

17、ants to sense the differences in day lengths so that they can tell the seasons are changing. They found that the protein can be activated (激活) by sunlight.Plants produce this protein every day in the late afternoon throughout the year. If there is no light at this time, for example, in winter when t

18、he sun goes down early, the protein wont be activated. But when spring comes and the days get longer, the protein can be activated by day-light and the plants “know” it is time to flower. Although researchers have only studied how the FKF1 protein works in some experimental plants, they believe it i

19、s similar in many other plants, including crops like rice and wheat. This could be useful to the agricultural industry.“If we can control the timing of flowering, we might be able to increase crop production by speeding or delaying this, said Takato Imaizumi, assistant professor at the University of

20、 Washington and leader of the study. “Also, if we could control the timing of flowering in horticultural (园艺的) plants, they may be worth more commercially (商业上)” New technology based on this research might also lead to higher production of biofuel (生物燃料) plants. This would be helpful for providing e

21、nergy.1. How do plants know when to flower?A. They receive messages from other plants.B. A certain protein tells them the time to flower.C. They are genetically (基因遗传上) timed to flower.D. Sunlight produces a certain protein in them to help them flower.2. What can we learn from the article?A. We are

22、getting closer to controlling plant flowering times. B. Plants are more sensitive to cold weather and shorter days.C. When there is no sunlight, the FKF1 protein wont be produced.D. Researchers have studied how the FKF1 works in rice and wheat.3. The study mentioned in the article may help us unders

23、tand how to _.A. increase the number of species of horticultural plants B. increase production in the agricultural industryC. have plants that flower all year round D. produce more chemical energy4、 The need for a surgical operation, especially an emergency operation, almost always comes as a severe

24、 shock to the patient and his family. Despite modern advances, most people still unreasonably fear hospitals and anesthetics (麻醉药). Patients do not often believe they really need surgery-cutting into a part of the body as opposed to treatment with drugs. In the early years of this century there was

25、little specialization in surgery. A good surgeon was capable of performing almost every operation that had been devised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves

26、 (阀门;心脏或血管的瓣膜) repaired. Clogged blood vessels can be cleaned out, and broken ones mended or replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to

27、 carry out every type of modern operation. The scope (范围, 广度, 机会) of surgery has increased remarkably in this century. Its safety has increased too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example to certain types of b

28、irth defects (缺陷) in newborn babies, and, at the other end of the scale, to life-saving operations for the octogenarian (八旬老人). The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be b

29、ack at work in two or three weeks. Many developments in modern surgery are almost unbelievable. They include the replacement of damaged blood vessels with simulated ones made of plastic; the replacement of heart valves with plastic substitutes; the transplanting of tissues such as the lens of the ey

30、e; the invention of the artificial kidney to clean the blood of poisons at regular intervals and development of heart and lung machines to keep patients alive during very long operations. All these things open a hopeful vista (前景,远景) for the future of surgery. One of the most revolutionary areas of

31、modern surgery is that of organ transplants. Until a few years ago, no person, except an identical twin, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of x-rays and

32、 special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have been reasonably successful in animals, though rejection problems in humans have yet to be solved. Spare parts surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the distant future. As
