Text APolice Officer Tidwell left the station just after 8 a.m. on Sunday June 4. He had spent an uneventful night on duty and was looking forward to his day of rest. By habit he took a short cut down the path behind Dugby Hall road and after a minute or two he saw a man climbing down a drainpipe from an open bedroom window of number 29. In silence Tidwell crept into the garden. The man reached the ground and was dusting himself down when he felt his arm gripped.“It’s 8:15 on a Sunday morning,” said the officer, “and this sort of thing seems an un likely adventure at such a time. Would you mind explaining?”The man was obviously startled but kept calm. He said, “I know what you’re thinking, officer, but it isn’t true. This is a funny mistake.”“It’s part of my job to take an interest in unusual even ts.I think you’ve just left this house in a manner other than the customary one. That may be quite innocent, but I’d like to make sure.” Tidwell took out his notebook and a pen. “Name, address and occupation and then, please, tell me your story.”“Charlie Crane, lorry driver, from Nottingham, 51 Breton Street. My story…”“Yes. What were you doing like a fly on that wall, Mr. Crane?” “Well, I had a breakdown yesterday and had to stay the night here. Bed and breakfast. The landlady’s name is Mrs. Fern. She g ave me breakfast at seven, and I was out of here in the right way and down at the lorry by half past seven. Only when I felt around for a cigarette, did I realize I’d left $80 in my envelope under the pillow here at number 29. I always put it under my pill ow at night. It’s a habit I’ve got into. I even do it at home…”“I see. Why didn’t you miss it when you went to pay Mrs… What’s her name?”“I’d paid her last night. You’ve got to pay when you take the room, see? So I came rushing back, but it’s Sunday, a nd she’d gone back to bed, and could I wake her? I rang the bell and banged on the front door for ten minutes before I came round here to the back and spotted my bedroom windowsill open. Up I went, then, up this pipe. It’s a trick I learnt in the army. She didn’t make the bed, and the money was still there. You know the rest, and I hope you believe it because…”“Mr. Crane, whatever are you doing here? I thought you’d gone an hour ago.” It was Mrs. Fern, speaking from the kitchen window at the corner of the house.1. Why was Tidwell walking along the path behind Dugby Hall road?[A] He usually discovered something suspicious along that way.[B] He had an appointment with a man at number 29 there.[C] He chose to go that way by chance.[D] He knew he would get home quicker that way.2. The police officer questioned the man because[A] he had seen him do a strange thing.[B] he thought he knew him.[C] the man had fallen and needed attention.[D] the man had tried to escape from a window.3. Crane stayed the night at number 29 because[A] he had lost his way in the dark.[B] there was something wrong with his lorry.[C] Nottingham was too far for him to drive that night.[D] he had suddenly fallen ill that night.4. Why did n’t the man realize he had left his money at the landlady’s earlier?[A] Because he trusted the landlady.[B] Because he had put the money under the pillow.[C] Because he had no occasion to remember the money thing.[D] Because he was in such a hurry that morning.5. In the end, Officer Tidwell would probably[A] take Crane back to his office.[B] accuse Crane of misbehaving.[C] just leave Crane alone.[D] force Crane to pay Mrs. Fern some money .Text BUS consumers rediscovered their appetite for shopping in June, boosting spending by a strong 0.8 point. It was fresh testament to the economy’s incentive as it headed into the third quarter. The monthly increase in spending, reported by the Commerce Department on August 2, came after consumers tightened their belts in May, leaving spending flat. Consumer spending plays a key role in shaping the economic activity and thus is closely watched by Federal Reserve chairman Alan Greenspan and other economists.Incomes, the fuel for further spending, grew at a nice clip of 0.5 percent in June, better than the 0.2 percent gain registered in the previous month. The pickup in income growth dovetailed with an improvement in the jobs climate in June, when the unemployment rate fell to 5 percent, a nearly four year low. Both the increase in incomes and in spending were the largest since April. The spending and income figures are not adjusted for inflation.The performance in consumer spending and income growth in June was in line with analysts’ expectations. Before the release of the report, they were forecasting the spending to rise by 0 8 percent and incomes to increase by 0.4 percent. With spending surpassing the income growth, the personal saving rate —savings as a percentage after-tax income —dropped from 0.4 percent in May to zero in June. That was the worst showing since October 2001, when the saving rate fell into the negative territory. Economists, however, cautioned that the picture of savings isn’t as bad as it looks. The savings rate doesn’t provide a complete picture of household finances becaus e it doesn’t capture gains from such things as real estate or financial investment. High energy prices didn’t hinder consumer spending in June.Consumers boosting spending on big-ticket goods, including cars and appliances, by 2 9 percent, compared with a spending cut of that size in May. Spending on nondurable such as foodand clothes went up by 0.7 percent in June after dipping by 0.2 percent the month before. Spending on the services rose 0.5 percent in June, following a 0.6 percent in May. Consumers did their part to keep the economy moving ahead at a nice clip of the 3.4 percent in the April-to-June quarter as a whole, the government reported last week. Analysts believe the economy will do even better in the current quarter if businesses replenish inventories.One of the main forces tempering economic growth in the second quarter was that businesses cut back on inventories. That chopped 2.3 percentage points from economic growth during the second quarter. Wanting to make sure expanding economic activity and rising energy prices don’t fan inflation, Federal Reserve Policy-makers are expected to bump up interest rates by another quarter percentage point when they meet next Tuesday.6. All the following factors contribute to the increase spending in June EXCEPT[A] optimistic employment situation.[B] income increase.[C] decrease of unemployment rate.[D] inflation.7. In June,[A] the increased figures take all the factors into consideration.[B] the spending increase percentage is higher than the income increase percentage.[C] personal saving rate decreases because the low incomes increase percentage.[D] the high energy price does affect the consuming enthusiasm.8. According to Para. 4, the picture of household income[A] can be reflected by financial investment.[B] can be reflected by household finances.[C] cannot be reflected by the saving rate.[D] cannot be reflected by the household assets.9. The Federal Reserve Policy-makers are likely to increase interest rate to[A] curve the rising energy price. [B] avoid the inflation.[C] trigger consuming. [D] enlarge economic activity.10. What does this passage mainly talk about?[A] High income increase.[B] Low unemployment rate.[C] Increasing spending in June.[D] The economic increase in the third quarter.Text CBiotechnology in one form or another has flourished since prehistoric times. When the first human beings realized that they could plant their own crops and breed their own animals, they learned to use biotechnology. The discovery that fruit juices fermented into wine, or that milk could be converted into cheese or yogurt, or that beer could be made by fermenting solutions of malt and hops began the study of biotechnology. When the first bakers found that they could make a soft, spongy bread rather than a firm, thin cracker, they were acting as fledgling biotechnologists. The first animal breeders, realizing that different physical traits could be either magnified or lost by mating appropriate pairs of animals, engaged in the manipulations of biotechnology.What then is biotechnology? The term brings to mind many different things. Some think ofdeveloping new types of animals. Others dream of almost unlimited sources of human therapeutic drugs. Still others envision the possibility of growing crops that are more nutritious and naturally pest-resistant to feed a rapidly growing world population. This question elicits almost as many first-thought responses as there are people to whom the question can be posed. In its purest form, the term “biotechnology” refers to the use of living organisms or their products to modify human health and the human environment. Prehistoric biotechnologists did this as they used yeast cells to raise bread dough and to ferment alcoholic beverages, and bacterial cells to make cheeses and yogurts and as they bred their strong, productive animals to make even stronger and more productive offspring. Throughout human history, we have learned a great deal about the different organisms that our ancestors used so effectively. The marked increase in our understanding of these organisms and their cell products gives us the ability to control the many functions of various cells and organisms. Using the techniques of gene splicing and recombinant DNA technology, we can now actually combine the genetic elements of two or more living cells. Functioning lengths of DNA can be taken from one organism and placed into the cells of another organism. As a result, for example, we can cause bacterial cells to produce human molecules; cows can produce more milk for the same amount of feed, and we can synthesize therapeutic molecules that have never before existed.11. Human beings began to use biotechnology[A] when they could walk on their feet.[B] before they could plant their own crops.[C] after they realized that they could raise their own animals.[D] as soon as scientists began their studies on biotechnology.12. The sentence “This question elicits…” in paragraph 2 means[A] people have different responses to the question “what is biotechnology”.[B] the question “what is biotechnology” has been posed to many people.[C] responses to the question “what is biotechnology” should be made on the spot.[D] only those who are asked the question “what is biotechnology” can answer it.13. Biotechnology enables us to[A] increase the function of various cells and organisms.[B] change the DNA of human beings.[C] find new human molecules.[D] produce more milk by increasing the number of cows.14. The application of biotechnology helps us[A] improve living space.[B] produce more products at the same cost.[C] increase the number of various cells.[D] find new animal molecules.15. The primary purpose of this article is[A] to narrate the development of biotechnology.[B] to describe the picture of biotechnology.[C] to prove that the biotechnology industry is a promising industry.[D] to explain the term of biotechnology and its significance.Text DT he popular dietary supplement ginseng is claimed to improve one’s mood and all-around vigor, but a new study published in the Journal of the American Dietetic Association suggests that ginseng has little of any effect on psychological health.The study, conducted by researchers at Oregon State University and Wayne State University, is one of the most extensive peer-reviewed studies of ginseng ever conducted.“Ginseng is being marketed to relatively healthy young people as a way to feel even better—a kind of yuppie supplement,” said Bradley J. Cardinal, an associate professor in the College of Health and Human Performance at Oregon State. “We found it had no real effect on mood at all. It certainly did not live up to some of its over-enthusiastic marketing claims.”Among the claims, the authors say, was that ginseng enhances mood, leads to positive well-being, and generally makes you feel better. Marketing ploys(策略) used to push ginseng promoted its use by astronauts and professional athletes.The study by Crdinal and Hermann J. Engels of Wayne State University focused only on the alleged psychological properties of ginseng. The researchers gave a regular, 200-mg daily dose of ginseng to one group of volunteers for eight weeks. A second group received a double dose of 400-mg daily; the third group received a sugar pill. None of the individuals knew what they were taking.At the end of the eight-week period, the researchers measured the effects of the supplements on the volunteers “total mood disturbance” using a 65-que stion “Profile of Mood States” inventory.To eliminate bias, the researchers evaluated the tests without initially knowing which subjects were taking ginseng and which were taking placebos. They compared the results with a baseline survey of the volunteers taken just prior to the study. They found no significant difference among the three groups.In this latest research, the group taking 200-mg of ginseng experienced a 2.5 percent increase in positive feelings during the eight weeks, but the group taking a placebo had a greater increase, 5.0 percent. The largest gain in positive feelings, 7.7 percent, went to the group taking 400-mg of ginseng, but all of those numbers were within a statistical margin of error, making the differences insignificant, the researchers say.Cardinal said the most important category was Total Mood Disturbance, because it looked at the broad spectrum(范围) of mood enhancement experienced by the volunteers. The 200-mg group experienced a greater increase, 1.8 percent, than the 400-mg group, which increased only 0.3 percent. The placebo group was in between with a 1 percent increase.“Statistically, there really was no difference between the groups that took ginseng, and the group that didn’t,” Cardinal said. “It is still possible that ginseng may h ave an effect on certain individuals, or certain populations, such as the sick and the elderly. But higher doses also may bring on unwanted side effects. These are issues that need to be clarified with additional well controlled studies in the future.”Cardinal says their study used more volunteers (83) for a longer duration than almost all the other studies, and they even sent their ginseng to an independent laboratory to ensure that it was of high quality.Their double-blind, placebo-controlled study was designed to eliminate bias by both the volunteers and the researchers themselves. “The bottom line,” Cardinal said, “is that ginseng doesn’t seem to do much to enhance the psychological well-being of normal, healthy adults.”16. In the view of Bradley J. Cardinal,[A] ginseng can enhance the mood of human beings.[B] marketing claims overstate the ginseng effect on mood.[C] the ginseng leads to positive well-being.[D] the ginseng generally makes you feel better.17. The study by the researchers of Wayne State University mainly focused on[A] physical properties of ginseng.[B] unwanted side effects of ginseng.[C] positive effects of ginseng.[D] psychological features of ginseng.18. What’s the result of the study?[A] There is significant difference among the groups who took different doses of ginseng.[B] The group taking the higher doses of ginseng gains the largest increase of positive feeling.[C] The 400-mg dose group experiences the greatest increase of Total Mood Disturbance.[D] It is possible that ginseng may have a positive effect on certain groups of people.19. The researchers sent their ginseng to an independent laboratory to[A] analyze the collected data.[B] make sure the quality.[C] compare the quality of ginseng.[D] measure the effect on mood.20. Which of the following is NOT a measure taken to eliminate the bias?[A] None of the volunteers knew which subjects they were taking.[B] None of the evaluators initially knowing what the volunteers were taking.[C] The placebo-controlled study is used.[D] The effects of the supplements were measured by a 65-question inventory.语境词汇Text A1. uneventful a.无重大事件的，平静的2. by habit 出于习惯，习惯使然3. dust down 除去…的灰尘4. grip vt.紧握，抓牢n.控制；把手5. startle vt.使惊愕，使吃惊6. spot vt.认出，发现；弄脏n.斑点；场所Text B1. testament n.证明，证据2. clip n.步伐，节奏3. in line with 和…一致4. caution v.警告，告诫5. nondurable n.非耐用品a.不耐用的6. dip v.&n.（价格等）下跌，（消费额等）下降；浸泡，蘸Text C1. ferment v.（使）发酵；（使）骚动2.fledgling n.无经验的人；刚学会飞的幼鸟3. manipulation n.运用；操纵4. envision vt.想象，展望5. therapeutic a.对身心健康有益的；治疗的6. nutritious a.有营养的7. beverage n.饮料8. synthesize vt.用合成法制造；综合,合成Text D1. associate a.副的；联合的vt.结交；联想2. ploy n.策略；手法3. property n.性质，属性；财产4. disturbance n.烦恼；打扰，妨碍5. inventory n.（商品的）目录，盘存6. placebo n.安慰剂7. margin n.差数；页边的空白处；边界8. spectrum n.范围；系列；光谱难句突破Text A1.
