The other day in school, we were discussing jobs. Our teacher, Mrs. Bolt said that career was very important and that it was never too early to think about your life’s work. Most of the young boys really were not too sure about what they wanted to be. But I knew exactly what I wanted to be, and when Mrs. Bolt asked me, I replied “A truck driver.”
“A truck driver?” repeated Mrs. Blot. “Why do you want to be one, Tom?”
“Because truck drivers are always on the move. They do not have to sit at desks all day. They are out on the road and they see a lot of the country. The pay is good, too. And you never have any homework.”
The class laughed.
“Well, Tom.” answered Mrs. Bolt. “You certainly sound quite enthusiastic (熱情的). I guess that you don’t like sitting at a desk or doing homework. Is that correct, Tom?”
“Yes, I guess so, ” I said.
“Well, since you are so interested in becoming a truck driver, I think you should look into the field a little further. I want you to go to the library and take out a book on truck driving. And I want you to write a paper on it and hand it in at the end of the month.”
That’s the last time I’ll never tell anybody my secret ambition (雄心).
46．Mrs. Bolt suggested Tom write a book report because         .
A．she was angry with him.
B．she wanted him to learn about the other side of truck driving.
C．she was making fun of him.
D．she wanted the whole class to follow him
47．Which of the following is NOT true?
A．The writer thinks that truck drivers are well paid.
B．What Tom said made his classmates laugh.
C．It seemed as if Tom did not enjoy doing his homework.
D．Mrs. Bolt didn’t want Tom to become a truck driver.
48．Tom wouldn’t tell about his ambition any more because          .
A．he didn’t think his ambition could come true.
B．he just got more homework to do.
C．he was laughed at by the whole class.
D．he would not be able to become a truck driver.
49．What can we infer about Mrs. Bolt?
A．She was unkind to her students.            B．She was unfit for her position.
C．She was a teacher with ripe experience.  D．She always did something strange.

   For the people living in the Nile Basin, the river is their life:. This 6,825 km waterway, whose watershed（流域） covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts. Its potential for fishing, tourism and shipping is great—but so are its challenges.
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well. Today, about 160 million people depend on the Nile River for their living. Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture. The frequent drought（干旱）adds to the urgency.
Water quality is also a problem. Precious soil is washed out to sea. Wastes from industry and agriculture create pollution. Higher concentrations of salt influence irrigated soils. Water-borne diseases continue unchecked. In areas where it's hot and damp, water hyacinths choke off lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day. They’ve seen the river change course, and their only source（來源） of water thickened with mud. They’re very poor and have few choices.
But a new program, the Nile Basin Initiative （NBI），is offering very practical assistance. The program is more than just a water-management project. It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions（解決辦法）. Half the Nile Basin's countries are among the world's poorest nations；yet, somehow, they must find the  resources, skills and political will to overcome these challenges.
68. What are the great challenges the Nile Basin faces？
A. The development of .shipping industry.
B. Overfishing of native people.
C. Water shortage and water quality.
D. Increasing population and tourism.
69. The underlined word “hyacinths”（in Paragraph 3） refer to “          ”.
A. animals                           B. plants                     C. rocks                                D. salts
70. The program NBI is mainly aimed at           .
A. preventing water pollution                             B. changing the river course
C. improving living condition of the poor
D. preventing land from becoming desert
71. What would be the best title of this passage？
A. People's Life in Egypt and Sudan
B. Frequent Drought in Egypt and Sudan
C. The Poorest Countries in the Nile Basin
D. The Ecosystem Problems in the Nile Basin

.Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn't matter where you live--in the middle of a modern city, or a faraway village--the chances are that you' 11 be disturbed by jet planes, transistor radios, oil - powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they' re working.
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(專心) suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much(music, for example) may even help people to concentrate.
56. According to this passage, the noise pollution __
A. has become the worst in the countryside  B. has become better in big cities
C. has spread from cities to villages      D. has been controlled in modern cities
57. What does background music refer to?
A. Music played while people are working.   
B. Music played in the backyard.
C. Noise that continues while you' re listening to other noises.
D. Music used to help people to concentrate.
58. Some people have their hearing harmed __
A. while listening to pop music            B. in complete silence
C. when speaking loudly                  D. while watching TV
59. Which of the following isn't included among the things causing noise?
A. trucks           B. motorcycles   C. electric engines   D. jet planes
60. Scientists have discovered that what prevents people from concentrating on something is
A. all kinds of noise                   B. great changes in the level of noise
C. background noise                  D. popular music

C
Sometimes we cry because we are sad and sometimes because we are extremely happy．An irritant(刺激物)，such as onion(洋蔥) smell or grains of sand in the eye，can also make cry．In this case tears perform an obvious role in getting rid of substances that might harm the surface of the eye．
Dr．William Frey of the Dry Eye and Tear Research Center at St．Paul in Minnesota，USA，believes that tears from emotional causes may perform a similar role．He thinks that crying could get rid of emotional stress by washing away a chemical in the blood caused by strong emotions. To prove his theory, he hopes first to identify this chemical and then see if it is found in tears of sadness or happiness．  
So far, Dr．Frey has failed to find out the difference between emotional tears and tears caused by an irritant in the eye．This may be because these substances themselves cause a degree of stress and emotion．What he has identified in all tears is a variety of biochemicals(生化物)which are one of the causes of stress．A more detailed study may help us understand why sufferers from stress-related disorders cry less often than healthy people．Dr．Frey is also very interested to see if there are any physiological(生理學的)explanations for why women，in general，cry five times more often than men，on average．
64. The main purpose of Dr．Frey’s study of tears is to           
A. show that there are two types of tears，caused by irritants and by emotions
B. find out the cause of stress-related problems and emotional disorders
C. explain why women cry more often than men
D. prove that tears can remove a chemical in the blood caused by strong emotions
65. Which of the following is true according to the passage?
A. Tears fail to help get rid of emotional stress．
B. Irritants in the eye result in tears without causing stress and emotion．   
C. Healthy people cry more often than those with stress-related problems．
D. The biochemical identified by Dr．Frey has nothing to do with stress．
66. We can learn from the passage that __________．
A. crying does us more harm than good
B. inner feelings don’t affect our bodies
C. sorrow may cause some chemicals in our blood
D. emotional tears are different from tears caused by irritants in the eye
67. Dr．Frey believes that tears from emotional causes may play a role in getting rid of ______．
A. emotional stress by washing away a chemical in the blood
B. onion smell or grains of sand
C. sufferings from irritants
D. substances that might not harm the surface of the eye

　　When did you last see a polar bear? On a trip to a zoo, perhaps? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3℃, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group, this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.
　　Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits (or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system(循環(huán)系統(tǒng)) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.
　　The main benefits(or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says. "When I go into the water, I pour my troubles into the ocean and let them float away."
51. The members of the Polar Bear Club must meet the following requirements except that_____ .
　A. they should be easy to make friends with
　B. they must swim outdoors at least 8 times in the four cold months
　C. they must agree to swim outdoors from November through February
　D. they must reach the age of 60
52. Doctors _____ .
　A. encourage people to take part in cold-water swimming actively
　B. point out the possible danger of blood illness during cold-water swimming
　C. believe swimming is helpful both in winter and in summer
　D. have different ideas about the medical effects of cold-water swimming
53. According to the passage, some doctors believe it is true that _____ .
　A. you are healthy if cold-water swimming turns your skin color blue
　B. cold-water swimming causes more heart attacks in summer than in winter
　C. cold-water swimming can make the body temperature dangerously high
　D. Polar Bears are bears swimming in freezing water
54. The Polar Bears like to swim all the year round, for _____ .
　A. they can remain young   B. it is an easy way to keep the body warm in winter
　C. they find it enjoyable and interesting D. they might meet fewer troubles in life
55. The passage is mainly about _____ .
a group of cold-water swimming lovers                  B. the polar bears' life  
　C. doctors' ideas about cold-water swimming            D. the requirements of the Polar Bear Club

Astronauts’ meals have come a long way from the free-dried powders and semi-liquid pastes of decades ago, now US scientists want to grow vegetables in mini-greenhouses on the moon.
Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables. Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers—and eventually food-oh the moon.
This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminum frame. It is designed to safely land a laboratory plant on the lunar surface, and protect it while it grows.
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $20 million to any entrant who can launch, hand and operate a rover on the lunar surface.
Paragon officials say future testing of the “Lunar Oasis” will be driven by Odyssey’s flight schedule, which will not happen until 2012 at the earliest.
When it does lift off the greenhouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days, it can complete its life cycle in single lunar night.
“Coloizing the Moon or Mars seems so far away, but it is important that we do this research now, ” Paragon president Jane Poynter said.
“It takes a long time to get a lot of research, and to get integrated, reliable efficient systems before colonists move in,” she said.
57．The article is written mainly to________.
A．predict the astronauts’ meals in the future
B．introduce an experiment “Lunar Oasis”
C．tell us the future development of astronomy
D．focus on the human’s great progress
58．The article implies that_________.
A．a(chǎn)stronauts can grow flowers in space at present
B．Paragon and NASA will carry out the test separately
C．Lunar Oasis is a series of experiments carried out in space
D．the earliest testing of the Lunar Oasis may be in 2012
59．The underlined word “colonists” in the last paragraph probably has the meaning of________.
A．plants       B．wild beasts       C．human beings   D．scientists
60．The sees of Brassica will be contained in the greenhouse mainly because__________
A．their life cycle is much shorter
B．they are more nutritious than other food
C．they are related to Brussels sporouts and cabbage
D．they are very delicious

Gorillas are born with an international sign language of gestures that they use to communicate，says a new study from the University of St Andrews in Scotland.
From beating their chests to putting objects on their heads，shaking their arms，and even bouncing on all fours，the animals use more than 100 gestures to communicate with each other
Professor Richard Byrne，a psychiatrist involved in the research，says it was hard to figure out the meanings of the gestures.
“We don't really know what the animals are thinking. Often the gestures have more than one meaning，depending on the context，”says Byrne.
The study showed that the gorillas did not learn the ges­tures from each other，as had been expected，but performed them instinctively (本能地).
“Everyone had assumed different groups of gorillas would learn different gestures，”he says. “But that's not what we found. The more sites we went to ,the more we saw the same gestures being used. They seem to be naturally equipped with a pretty complex system of communication.”
The study also found that gestures were performed with close attention to the potential audience，so that silent sig­nals，for example， were only given when other apes could see them. Other gestures，such as the "disco arm shake" were only ever seen directed towards humans.
Byrne believes that the findings may explain how the human language developed.
“There has always been speculation（猜測）that the origins of the human language might lie in gestures，”he says.
“Many researchers have therefore studied the gestural communication of the great apes for clues to the evolution­ary origins of human gestures，”he adds.
Several studies have shown that great apes are capable of imitating gestures. However，the scientists found that what appeared to be copies of human actions were actually gestures the apes were already able to make themselves. They're “reusing” gestures from their own repertoire，not learning new ones.
64.According to the passage，Richard Byrne's research has found      .
A. different groups of gorillas would learn different gestures
B. gorillas know the sign language from birth
C. how gorillas learn from each other
D. gorillas develop a variety of languages when growing up
65.Why can't the researchers really know the meanings of gorilla gestures?
A. Because gorillas possess the ability of making many kinds of gestures.
B. Because they haven't made deep research into the animal.
C. Because a gorilla gesture may have different meanings.
D. Because gorillas can't exactly express their thoughts.
66.If a gorilla wants to make a silent gesture towards another gorilla，he      .
A. needs to know how many other gorillas are watching him
B. needs to make noise first in order to draw attention
C. will first make sure his gesture can be seen
D. will first consider whether he can carry out his gesture
67.According to the passage，many scientists study the sign language of great apes in order to      .
A. find the origins of the human language
B. find ways for people to communicate with apes
C. learn how animals communicate
D. discover the meanings of animal gestures

D
Is a recently discovered hormone the reason why folks who lose weight can’t keep it off?
Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just fat. After trying all sort of diets that didn’t work, she has to go to the stomach – bypass surgery (胃部迂回手術(shù)), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most. Result: she simply couldn’t eat the way she used to. In three years, Wilson is one third of her former weight.
Wilson’s experience is not all that unusual, and while doctors still aren’t exactly sure what is going on, a report in last week’s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason we feel hungry and it’s hare for didters to keep weight off.
Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the leading Dr. David of the University of Washington says, “I feel very solid about two of them.” The first is that ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is that ghrelin levels are higher on average in people who have lost weight from dieting.
Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as most people of normal weight. After all, ghrelin is produced by cells in the stomach. Years ago, leptin, a hormone was found as an appetite suppressant (食物抑制劑). But after years of trying, it had to be given up.
What doctors suspect is that both leptin and ghrelin are part of a complex system of brain and body chemicals that govern weight and appetite. That does not mena pharmaceutical (藥物的) weight control is forever out of the question. “In the next ten years, we will be able to develop new drugs to help people lose weight healthily and effectively.”
47．What can we learn about ghrelin according to the passage?
A．After meals ghrelin levels are higher in the bloodstream.
B．People who have lost weight have less ghreilin in their body.
C．Without ghrelin, people are really difficult to lose weight.
D．Ghrelin is something produced by cells in the stomach.
48．What is Dr. David not sure?
A．pharmaceutical weight control is impossible.
       B．There is less ghrelin in the bypass patients.
C．new drugs will be developed in 10 years.
D．ghrelin levels are higher in people on diet.
49．In fact, people’s weight and appetite are controlled by        
A．ghrelin and leptin                      B．hormone and medicine
C．brain and body chemicals                  D．stomach and food
50．What can we infer from the passage?
A．People with a lower ghrelin level go hungry easily.
B．Doctors managed to use leption to control the appetite.
C．Doctors are optimistic about how to lose weight healthily.
D．The loss of appetite in bypass aptient is linked to leptin
