Our memory tells us who we are. Our memory helps us to make use in the present of what we have

7、 learnt in the past.In fact we have different types of memory, For example, our visual memory helps us recall facts and places. Some people have such a strong visual memory, they can remember exactly what they have seen, for example, pages of a book, as a complete picture.Our verbal (言语的) memory hel

8、ps us remember words and figures we may have heard but not seen or written: items of a shopping list, a chemical formula, dates, or a recipe.With our emotional (情感的) memory, we recall situations or places where we had strong feelings, perhaps of happiness or unhappiness. We also have special memorie

9、s for smell, taste, touch and sound, and for performing physical movements.We have two ways of storing any of these memories. Our short-term memory stores items for up to thirty seconds - enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items fo

10、r a lifetime. Older people in fact have a much better long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance (记忆) of when they were very young.Psychologists tell us that we only remember a few facts about our past, and that we in

11、vent the rest. It is as though we remember only the outline of a story. We then make up the details. We often do this in the way we want to remember them, usually so that we appear as the heroes of our own past - or maybe victims needing sympathy (同情).（分数：7.00）(1).Visual memory helps us recall a pla

Do dreams have meanings? These are questions which have troubled man for thousands of

15、years. The oldest surviving book on the interpretation of dreams is Egyptian and is nearly 4,000 years old. In ancient Greece, it was thought that people who were iii could be cured by telling their dreams. They would relate their dreams to their doctors who would tell them what they meant, and then

16、 give them medicine to make them well. The ancient Chinese believed that if a pregnant woman dreamed of a bear, she would have a son, and if she dreamed of a snake, she would have a daughter. There are many stories about dreams foretelling (预言) the future.2 We certainly do not now believe that dream

17、s foretell the future. Most scientists believe that dreams are based on events in our own life and on our feelings. The events are usually very recent, mostly within the last two days. Our emotions, on the other hand, our wishes, hopes and fears, may go back many years, even to early childhood.3 In

18、a dream, events are altered. A dream may contain parts of many real-life events. Most importantly, something that cannot be shown directly may be shown indirectly. For example, you might dream of driving a large car. This could mean net that you want to have a larger car, but that you desire power,

19、and maybe you want to control other people. Again, you may dream that you are an actor in a play. The play is about to start, but you have completely forgotten your lines. This dream may seem strange because you are not interested in acting, and you never want to be in a play. But the dream may mean

20、 that you have some other problem that you feel is too difficult for you to solve.4 Psychologists believe that dreams may be helpful to us. Indeed, people who have been allowed to sleep in experiments, but not allowed to dream, have become anxious and restless. And when they are later allowed to sle

Thats about 5,000 miles per hour: At this

25、 speed, youd get around the world -flying along the equator (赤道) - in less than 5 hours.The Hyper-X is an unmanned, experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine known as a scramjet (超音速冲压式喷气发动机).For an engine to burn fuel and produce energy, it

26、 needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. A scramjet engine goes as fast as a rocket, but it doesnt have to carry its own oxygen supply.A scramjets special design allows i

27、t to obtain oxygen from the air that flows through the engine. And it does so without letting the fast-moving air put out the combustion (燃烧) flames. However, a scramjet engine works properly only at speeds greater than five times the speed of sound.A booster rocket (助推火箭) carried the Hyper-X to an

28、altitude of about 100,000 feet for its test flight. The aircrafts record-beating flight lasted just 11 seconds. That brief journey on March 27 makes a major milestone on the way to a new breed of very fast airplanes, says Werner J. A. Dahm of the University of Michigan in Ann Arbor. In the future, e

29、ngineers predict, airplanes equipped with scramjet engines could transport cargo quickly and cheaply to the brink (边缘) of space. Such hypersonic jets could carry passengers anywhere in the world in just a few hours.Out of the three experimental Hyper-X aircrafts built for NASA, only one is now left.

30、 The agency has plans for another 11 -second hypersonic flight, this time at 10 times the speed of sound.（分数：15.00）(1).The Hyper-X broke the record because（分数：3.00）A.it was the first air-breathing jet planeB.it flew along the equatorC.it traveled at the speed of soundD.it reached a speed of about 5,

31、000 miles per hour(2).What kind of engine did the Hyper-X use?（分数：3.00）A.A jet engine that carries its own oxygen supplyB.A jet engine that uses no oxygenC.A scramjet engine that doesnt carry its own oxygen supplyD.A rocket engine that carries its own oxygen supply(3).Which of the following is NOT t

32、rue of the scramjet engine?（分数：3.00）A.It has been used on passenger planesB.The air it breathes does not put out the combustion flamesC.It works at speeds greater than five times the speed of soundD.It goes as fast as a rocket(4).What does Werner J, A. Dahm say about the Hyper-X test flight?（分数：3.00

33、）A.It was unsuccessful because it lasted only 11 secondsB.It is a very important event in developing very fast airplanesC.It allows people to fly at an altitude of 100,000 feetD.It can transport cargo quickly and cheaply to outer space(5).What does NASA plan to do?（分数：3.00）A.To build one more Hyper-

34、X aircraftB.To carry out three more Hyper-X experimentsC.To make the aircraft fly higher and longerD.To test another hypersonic flight at 10 times the speed of soundB第二篇/BBStop Eating Too Much/B“Clean your plate!“ and “Be a member of the clean-plate club!“ Just about every kid in the US has heard th

35、is from a parent or grandparent. Often, its accompanied by an appeal: “Just think about those starving orphans (孤儿) in Africa! “ Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying “clean the plate“, perhaps we should save

36、some food for tomorrow.According to news reports, US restaurants are partly to blame for the growing bellies (肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associa

37、te quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition (营养) professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, th

38、e same time that the American waistline (腰围) began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people

39、 surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who cant afford fine dining still prefer large portions. Seventy percent of those earning at least 150,000 per year prefe

40、r smaller portions; but only 45 percent of those earning less than 25,000 want smaller.Its not that working class Americans dont want to eat healthy. Its just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paych

41、eck, happy to save a little money for next yearsChristmas presents.（分数：15.00）(1).Parents in the United States tend to ask their children（分数：3.00）A.to save food for tomorrowB.to wash the dishesC.not to waste foodD.not to eat too much(2).Why do American restaurants serve large portions?（分数：3.00）A.Beca

42、use Americans associate quantity with valueB.Because Americans have big belliesC.Because Americans are good eatersD.Because Americans are too weak(3).What happened in the 1970s?（分数：3.00）A.The US government called on its people to reduce their weightB.Health experts persuaded restaurants to serve sma

43、ller portionsC.The United States produced more grain than neededD.The American waistline started to expand(4).What does the survey indicate?（分数：3.00）A.Many low-income Americans want large portionsB.Twenty percent of Americans want smaller portionsC.Fifty-seven percent of Americans want large portion

44、sD.Forty-five percent of Americans want smaller portions(5).Which of the following is NOT true of working class Americans?（分数：3.00）A.They work long hoursB.They live from paycheck to paycheckC.They dont want to be healthy eatersD.They want to save money for presentsB第三篇/BBSunspots/BIts not surprising

45、 that sunspots (太阳黑子) were observed by ancient astronomers (天文学家). The largest sunspots on the sun can be seen without a telescope. It was not until the invention of the telescope (望远镜) in the early 17 th century, however, that systematic studies of sunspots could be undertaken. The great astronomer

46、 Galileo was among the first to make telescopic observations of sunspots.Sunspots are regions of extremely strong magnetic fields (磁场) found on the suns surface. A sunspot has a dark central core known as the umbra. The umbra is surrounded by a dark ring called the penumbra, where the magnetic field

47、, spreads outward. Sunspots appear dark because they are giving off less radiation. They are cooler than the rest of the suns surface.Sunspots are frequently observed in pairs or in paired groups. The members of a spot pair are identified as the leading spot and the following spot. They are identifi

48、ed by their position in the pair in terms of the direction in which the sun rotates (旋转).The number of sunspots at any one time varies. A large spot group may consist of as many as 10 groups and 300 spots across the sun. The number of spots changes in a fairly regular pattern called the sunspot cycl

49、e. The largest number occurs about every 11 years. At sunspot minimum, there are at most just a few small spots.The average lifetime of an individual spot group is roughly one solar rotation, which is about 25 days. The most persistent large spots, however, can survive for two to three months.（分数：15.00）(1).Car
