The department of weights and measures, we are a government agency. It“s our responsibility to see that all th

18、e scales measure a kilogram accurately so this is the way we use to adjust the scales. W: How did you check the scales before? M: We have an old standard weight that we used to use. It had to be replaced because it was imprecise. You see it was made of poor quality metal that was too porous. It abso

19、rbed too much moisture. W: Oh. So when the weather was humid it weighed more and when it was dry it weighed less. M: Exactly. And the variation can affect the standards of the whole country. So our department had the new weight made out of higher quality metal. W: How much did it cost? M: About 45 t

20、housand dollars. W: 45,000 dollars? For one kilogram weight? That“s more expensive than gold. Is it really worth that much? M: I“m sure it is. Industries depend on our government agency to monitor the accuracy of scales so that when they buy and sell their products there is one standard. Think of th

21、e drug industry, for example, those companies rely on high accuracy scales to manufacture and package medicine. What is the conversation mainly about? 解析 对话开始主持人便向 Dr. Thomas 提出是否可以谈谈官方标准重量砝码，接下来对标准砝码的使用、与过去砝码的比较和现用标准砝码的价格进行讨论，可知本篇对话主要话题是标准砝码，故选 B。A.Checking the accuracy of scales. B.Calculating the

22、 density of metals.C.Observing humidity of atmosphere.D.Measuring amounts of rainfall.解析：听力原文 What was the weight used for? 解析 主持人问 Dr. Thomas 这个标准砝码的用途是什么时，Dr. Thomas 回答说他们部门里的人用它检测全国的天平，并在全国范围内统一标准，故选 A。A.It has been rusty.B.It was not scientific.C.It was of low quality.

24、ght? 解析 当主持人得知标准砝码价格是 45,000 美元时十分吃惊，觉得它比金子还贵，于是询问 Dr. Thomas 标准砝码是否值这个价，但 Dr. Thomas 非常肯定地说所有的实业公司都依赖政府机关来监控天平的准确性，因此它们在购买和销售产品时，得有一个标准检测重量，并以医药行业为例来说明，所以 Dr. Thomas 认为这个价格是合理的，故选 D。Questions 5 to 8 are based on the conversation you have just heard. （分数：16.00）A.She is busy writing a biological arti

25、cle.B.She is busy with a program about endangered species.C.She is busy reading some books on economics.D.She is busy with two research papers. 解析：听力原文 W: Hi, Bill, how is it going?

W: That sounds pretty interesting. I“m getting frustrated with the two research papers I“m struggling with. M: Oh?

27、W: And can you believe they are both due on the same day? M: That“s tough. W: I“ll get through it. So what“s this you are reading? M: Well, it“s basically about the choices conservationists faced with. You know, on these days when funding is so hard to come by. W: Wait a minute. Is the focus on biol

W: Can you give me an example of what you mean? M: Take for instance, two animals, the spotted owl and

29、the tailed toad. The article says the toad is unique. It has no relatives. But there are a lot of varieties of owls. W: So, if that toad became extinct, we“d lose an important link in the chain of evolution, right? M: Exactly. But that isn“t so for the owl. So for conservationists, it might be clear

32、iled toad have been extinct.B.The varieties of the tailed toad are helpful to the research of evolution.C.If the tailed toad is well conserved, many other species will be better saved.D.If the tailed toad was extinct, some myth about evolution would lose. 解析：听力原文 What can be inferred about the taile

33、d toad? 解析 对话最后男士说这种长尾蟾蜍独特之处在于它没有任何的亲缘同类，女士于是得出结论说如果这种蟾蜍绝种的话，对于进化研究就少了一个重要的线索，随后男士对此表示肯定，故选 D。A.The man is busy preparing the research paper.B.The woman should hand two papers in on the same day.

C.Booming housing market.D.Rising interest rates.解析：听力原文 Many economists say U.S. growth will accelerate a bit soon, which will likely make it easier for other nations to sell their products in the world“s biggest economy.

45、Surging energy production is cutting costs and spurring U.S. economic growth, but rising interest rates are acting as brakes on expansion. Some shops are busier, because the United States and other wealthy nations are shaking off the recession and making more economic contribution. Key sectors of th

46、e U.S. economy, like housing, are strongly influenced by interest rates. Lower rates make it easier for families to borrow the money to buy homes and businesses to get the equipment they need to expand. With that in mind, the U.S. central bank has been endeavoring to stimulate the economy by cutting

47、 interest rates. Part of that effort involves buying tens of billions of dollars of securities each month, a program that is being reduced or “tapered.“ If the stimulus continues for too long, it might spark inflation, which could hurt the economy. A surge in U.S. energy production will help overcom

48、e the impact of rising interest rates. Oil industry experts say growing use of hydraulic fracturing or “fracking“ has sharply increased U.S. production of oil and natural gas. The wider use of fracking is boosting U.S. oil production, cutting the cost of crude oil imports, and leaving people with mo

49、re money to consume. Critics say burning more fossil fuels may increase climate change and voice concerns about the impact of fracking on the environment and public health. Industry spokesmen say the practice is safe, but opponents say some gas wells that use fracking technology have polluted nearby water wells, and they urge more scientific study. According to the passage, what is stimulating the U.S. economy? 解析 短义中提到，上涨的能源生产在降低了成本的同时促进了经济的增长，但是上涨的利息率却起着反作用，故选 B。A.Increasing interest rate.B.Decreasing financial products.C.Buyin
