27、le prevent it happening.D.The earthquake prediction can only locate potential areas of danger. 解析：听力原文 Now, you“ve been reading articles about the tremendous damage done to life and property by earthquakes. That“s why seismologists have been working so hard to develop methods of earthquake predictio
28、n. We can now predict earthquake fairly well, but the predictions only locate potential areas of danger. They don“t predict the specific time and location at which an earthquake is likely to occur. Today I want to introduce you to three prediction models that have been developed. The first predictio
29、n model looks along earthquake faults, those cracks in the Earth“s crust, to find what are known as seismic gaps. Seismic gaps are places where the fault has shown little or no seismic activity for a long time. This theory postulates that such places are due for a major shock. The second model relie
30、s on phenomenalike ground tilt. Using long cylindrical tubes containing water, observers noted that ground tilt tended to occur before major earthquakes. That led them to correctly predict the big Haicheng (HI CHUNG) quake of 1975the first successful earthquake prediction scientists have ever made.
31、A million people were evacuated from that Chinese city before the earthquake struck. Unfortunately, this method hasn“t worked consistently, so we can“t say it“s been perfected. The third model is based on the theory that major earthquakes closely follow a series of minor ones. Starting with the meas
32、urements and timing of the smaller quakes, a complex formula calculates the “times of increased probability“ of a much larger quake. Right now, this method, like the first method, cannot predict specific time and places, but that may change as it is further developed. For the moment, none of these m
33、odels can predict with reasonable levels of confidence. What can we know about the earthquake prediction according to the speaker? 解析 短文开头部分提到，地震学家一直致力于大力发展地震预报方法，已经可以很好地预测地震，但只能找到潜在的危险地区，不可预测地震发生的具体时间和地点。选项 D 与原文相符，故选 D。A.Seismic activity.B.An opening in the Earth“s crust. C.Crack in the Earth“s co
34、re.D.A lot of noise before an earthquake.解析：听力原文 What is the earthquake fault? 解析 短文在提到地震断层的时候，紧随其后就进行了解释，即地壳裂缝，故选 B。A.They termed the second prediction model.B.They observed ground tilt before earthquakes. C.They learned lessons from major earthquakes.D.They evacuated people from the city in time.解
35、析：听力原文 Why could the scientists correctly predict Haicheng quake of 1975? 解析 在解释第二种预测模型时，观察家指出，地面倾斜往往会发生在大地震之前。正因为如此，科学家于 1975 年第一次成功预报了地震。选项 B 与原文相符，故选 B。A.He believes the third model will be combined with the first one.B.He couldn“t agree with the second model any more.C.He has some reservations a
36、bout all the three models. D.He obviously doesn“t favor any of the three models at all.解析：听力原文 What is the speaker“s attitude toward the three prediction models? 解析 短文最后提出，就目前而言，没有哪种模型可以很有信心地，合理地做出地震预测。选项 C 表明作者持有保留态度，故选 C。（分数：7.50）A.20% adults are infected with HIV in Botswana.B.There aren“t aggres
37、sive AIDS prevention campaigns.C.Botswana“s HIV infected rate still remains high. D.People in Botswana suffer from shortages of vitamins.解析：听力原文 Patients with HIV often develop shortages of vitamins in the body. Researchers examined whether giving these patients a multivitamin with a mineral supplem
38、ent helps to improve the body“s natural defenses in fighting disease. For 30 years, AIDS has been a major health problem in some African countries south of the Sahara Desert. In Botswana, one of every four adults is infected with HIV. Yet the country also has aggressive AIDS prevention campaigns. Th
39、at is why Professor Marianna Baum decided to carry out her research on HIV and vitamins there. Professor Baum studied almost 900 newly infected adults in Botswana who had not yet been given anti-AIDS drugs that target HIV. The adults were divided into groups. Each group got different combinations of
40、 vitamins B, C, E, and the mineral selenium, or a placebo. Most patients with HIV do not have enough vitamins. Professor Baum says she thought the multivitamins by themselves or the mineral selenium by itself would help strengthen the immune system. She was wrong. “We were surprised to find that onl
41、y the combination was effective.“ Studies show that when people with HIV begin taking anti-retroviral drugs shortly after infection, they can stay healthy and are less likely to pass the virus to their sexual partners. But many patients do not have enough money to pay for treatment. Professor Baum s
42、ays the vitamin and mineral therapy combination should help people in low-income countries better control the virus. “A simple multivitamin supplementation with selenium provided early in HIV disease can actually slow the HIV disease progression, and it should be provided very early in HIV infection
43、.“ She says the vitamin therapy should not replace anti-retroviral drugs, but it can help people who cannot get those medicines. Why did Professor Marianna Baum decide to carry out her research in Botswana? 解析 短文提到 Botswana 时，介绍那里每四个成年人就有一个是艾滋病毒携带者，然而该同也有积极有力的艾滋病预防项目。选项 C 符合原文，故选 C。A.The combination
44、 of vitamin and mineral can help patients with HIV. B.The multivitamins by themselves would help strengthen the immune system.C.Vitamins help the body absorb mineral and keep it healthyD.HIV weakens the body“s natural defenses for fighting disease.解析：听力原文 What did Professor Marianna Baum find out ab
45、out vitamins and HIV? 解析 短文中提到，Baum 教授说她原来认为多种维生素或是硒自身都能增强免疫力，但是她错了。下文继续强调只有多种维生素和矿物质的组合才有效，故选 A。A.It is free of charge to the people with low income.B.It changes HIV infection in the long run.C.It slows rapidly the HIV disease progression.D.It can“t take the place of anti-retroviral drugs. 解析：听力原文
46、According to Professor Marianna Baum，what do we know about the vitamin therapy? 解析 短文最后转述了 Baum 教授的观点，维生素疗法不能替代抗逆转录病毒药物，却能帮助那些无法得到这些药物的病人。选项 D 符合原文，故选 D。（分数：7.50）A.To remain the sponsor of an event.B.To completely avoid paying tax.C.To get well-known and save money. D.To actively do some social char
47、ity.解析：听力原文 It is common nowadays for companies and industries to sponsor big sports events. For example, many companies sponsored the 8th National Games held in Shanghai in 1997. Then, what exactly do companies and industries get out of sponsoring big sports events, such as international games? And
48、 why need they do so? There is an obvious answer and a not-so-obvious one. The obvious answer is that they get known worldwide, particularly if they are the principal sponsor of an event. This is especially important when you consider the number of countries around the world that might show the even
49、t on TV. The not-so-obvious answer is that sponsorship can help firms to save money. Then how can they save money in this way? Companies can claim expenditures on sponsorship or “support to sport and the arts“ against the amount of tax that they owe. So, if they are going to have to pay tax anyway, why not spend the money on promoting their name or product? However, sponsorship is surely a very expensive business. So, how does one decide which events or activities to support? Companies spend a lot of time making sure that they have a perfect match betwee
