(D)
Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

D
A sunflower is a sunflower . A mobile phone is a mobile phone . But can you combine the two to do something for your local environment?
As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (能进行生物递降分解的) mobile phone was, this month, introduced by scientists.
Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸钾). These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.
As phone technology is developing so quickly people are constantly  throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. "The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it," said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.
67. The main idea of the passage is ________ .
A. the relationship between high tech and environment

D. to help consumers know which flower can best perform
69. What is the possible meaning of the underlined word ?
A. pleasant    B. poisonous    C. useful    D. new
70. Which of the following statements is NOT true ?
A.Engineers have designed a small transparent window to hold the rose seed .
B. Mobiles with biodegradable covers can do good to nature .
C.Manufacturers are under pressure to find ways of recycling mobiles .
D. The flower only grows when the phone is thrown away .

B
There is an English saying :“laughter is best medicine .”Until recently ,few people took the saying seriously .Now however ,doctors have begun to look into laughter and the effects it has on the human body .They have found that laughter really can improve people’s health .
Tests were carried out to study the effects of laughter on the body .People watched funny films while doctors checked their hearts ,blood pressure ,breathing and muscles .It was found that laughter had similar effects to physical exercise .It increases blood pressure ,the heart beating and breathing ; it also works several groups of muscles in the face ,the stomach ,and even the feet .If laughter exercises the body ,it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body .In one experiment doctors produced pain in groups of students who listened to different radio programmes .The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny programme .The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries ,some doctors in the United States now hold laughter clinics ,in which they help to improve their patients’ condition by encouraging them to laugh .They have found that even if their patients do not really feel like laughing ,making them smile is enough to produce beneficial effects similar to those caused by laughter .
61.Doctors have proved the following EXCEPT that      .
A.smiling does good to health     B.laughter can be tolerated
C.there is a way to reduce pain     D.laughter can work the muscles in the feet

D.to prove smile and laughter have the same effect

Passage Eighteen (Strictly Ban smoking)
If you smoke and you still don’t believe that there’s a definite link between smoking and bronchial troubles, heart disease and lung cancer, then you are certainly deceiving yourself. No one will accuse you of hypocrisy. Let us just say that you are suffering from a bad case of wishful thinking. This needn’t make you too uncomfortable because you are in good company. Whenever the subject of smoking and health is raised, the governments of most countries hear no evil, see no evil and smell no evil. Admittedly, a few governments have taken timid measures. In Britain for instance, cigarette advertising has been banned on television. The conscience of the nation is appeased, while the population continues to puff its way to smoky, cancerous death.
You don’t have to look very far to find out why the official reactions to medical findings have been so lukewarm. The answer is simply money. Tobacco is a wonderful commodity to tax. It’s almost like a tax on our daily bread. In tax revenue alone, the government of Britain collects enough from smokers to pay for its entire educational facilities. So while the authorities point out ever so discreetly that smoking may, conceivable, be harmful, it doesn’t do to shout too loudly about it.
This is surely the most short-sighted policy you could imagine. While money is eagerly collected in vast sums with one hand, it is paid out in increasingly vaster sums with the other. Enormous amounts are spent on cancer research and on efforts to cure people suffering from the disease. Countless valuable lives are lost. In the long run, there is no doubt that everybody would be much better-off if smoking were banned altogether.
Of course, we are not ready for such a drastic action. But if the governments of the world were honestly concerned about the welfare of their peoples, you’d think they’d conduct aggressive anti-smoking campaigns. Far from it! The tobacco industry is allowed to spend staggering sums on advertising. Its advertising is as insidious as it is dishonest. We are never shown pictures of real smokers coughing up their lungs early in the morning. That would never do. The advertisement always depict virile, clean-shaven young men. They suggest it is manly to smoke, even positively healthy! Smoking is associated with the great open-air life, with beautiful girls, true love and togetherness. What utter nonsense!
For a start, governments could begin by banning all cigarette and tobacco advertising and should then conduct anti-smoking advertising campaigns of their own. Smoking should be banned in all public places like theatres, cinemas and restaurants. Great efforts should be made to inform young people especially of the dire consequences of taking up the habit. A horrific warning – say, a picture of a death’s head – should be included in every packet of cigarettes that is sold. As individuals, we are certainly weak, but if governments acted honestly and courageously, they could protect us from ourselves.
1.Why do a few governments take timid measures toward smoking?
A.because they are afraid of people.
B.Because diseases cost a lot.
C.Because they are afraid of the cutting down of their revenue.
D.Because they are afraid of manufacturers.
2.The tone of this passage is
A.critical.
B.ironical.
C.distaste.
D.amusing.
3.What does the sentence “because you are in good company” mean?
A.you are backed by the government.
B.You are not alone.
C.You have good colleagues.
D.Governments are blind to evils of smoking too.
4.What is the best title of this passage?
A.World Governments should conduct serious campaigns against smoking.
B.World governments take timid measures against smoking.
C.smoking is the most important source of income to many countries.
D.tobacco industry spends a large sum of money on medical research.

Passage Fourteen(Antarctica and Environment)
Antarctica has actually become a kind of space station – a unique observation post for detecting important changes in the world’s environment. Remote from major sources of pollution and the complex geological and ecological systems that prevail elsewhere, Antarctica makes possible scientific measurements that are often sharper and easier to interpret than those made in other parts of the world.
Growing numbers of scientists therefore see Antarctica as a distant-early-warning sensor, where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from the United States, Switzerland, and France are pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet – a concern they believe the world at large should share.
The Transantarctic Mountain, some of them more than 14,000 feet high, divide the continent into two very different regions. The part of the continent to the “east” of the mountains is a high plateau covered by an ice sheet nearly two miles thick. “West” of the mountain, the half of the continent south of the Americas is also covered by an ice sheet, but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disappeared, the western part of the continent would be reduced to a sparse cluster of island.
While ice and snow are obviously central to many environmental experiments, others focus on the mysterious “dry valley” of Antarctica, valleys that contain little ice or snow even in the depths of winter. Slashed through the mountains of southern Victoria Land, these valleys once held enormous glaciers that descended 9,000 feet from the polar plateau to the Ross Sea. Now the glaciers are gone, perhaps a casualty of the global warming trend during the 10,000 years since the ice age. Even the snow that falls in the dry valleys is blasted out by vicious winds that roars down from the polar plateau to the sea. Left bare are spectacular gorges, rippled fields of sand dunes, clusters of boulders sculptured into fantastic shapes by 100-mile-an-hour winds, and an aura of extraterrestrial desolation.
Despite the unearthly aspect of the dry valleys, some scientists believe they may carry a message of hope of the verdant parts of the earth. Some scientists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them.
1.What is the best title for this passage?
A.Antarctica and environmental Problems.
B.Antarctica: Earth’s Early-Warning station.
C.Antarctica: a Unique Observation Post.
D.Antarctica: a Mysterious Place.
2.What would the result be if the West Antarctic Ice Sheet disappeared?

D.Sand dunes.
4.Which of the following is true?
A.The “Dry Valleys” have nothing left inside.
B.The “Dry Valleys” never held glaciers.
C.The “Dry Valleys” may carry a message of hope for the verdant.
D.The “Dry Valleys” are useless to scientists.

Passage Twelve (We Should All Grow Fat and Be Happy)
Here’s a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn’t eat this and she mustn’t that. Oh, but of course, she doesn’t want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it’s the surest way to an early grave. They spend a truly memorable evening together and never see each other again.
What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for ‘health cures’. For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don’t think it’s only the middle-aged who go in for these fads either. Many of these bright young things you see are suffering from chronic malnutrition: they are living on nothing but air, water and the goodwill of God.
Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they’re always hungry. You can’t be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood is a complete food, the advertisement says. ‘Just dissolve a teaspoonful in water…’. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they’re always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice!
What’s all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly people do so to attain a state of misery. It will be a great day when all the dieters in the world abandon their slimming courses; when they hold out their plates and demand second helpings!

Passage Eleven (Superconducting Materials)
The stone age, The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Welcome to the age of superstuff. Material science -- once the least sexy technology – is bursting with new, practical discoveries led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the picture: from house and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science.
The key to the new materials is researchers’ increasing ability to manipulate substances at the molecular level. Ceramics, for example, have long been limited by their brittleness. But by minimizing the microscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualities as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and never rust or corrode.
A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites – plastic reinforced with fibers of graphite or other compounds – made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantryman’s life by deflecting two bullets in the Grenada invasion.
Some advanced materials are old standard with a new twist. The newest fiberoptic cable that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane.
But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.
1.How many new materials are mentioned in this passage?
A.Two          B.Three          C.Four               D.Five
2.Why does the author mention genetic engineering and computer science?
A.To compare them with the new materials.
B.To show the significance of the new materials on the future world.
C.To compare the new materials to them.
D.To explain his view point.
3.Why is transition difficult?
A.Because transition requires money and time.
B.Because many manufacturers are unwilling to change their equipment.
C.Because research on new materials is very difficult.
[D]Because it takes 10 years.
4.Where lies success of a country in the New Age of superstuff?
A.It lies in research.
B.It lies in investment.
C.It lies in innovation.
D.It lies in application.

Researchers are placing robotic dogs (机器狗) in the homes of lonely people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and left satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激),” Edwards points out. “ The problem is how we promote (使成为现实) that, especially for those without friends or help. A robotic dog could be a solution.”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady, “When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not funny,” Beck says. “But it’s amazing how quickly we have given up that belief.”
“Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”
48. The purpose of Beck and Edwards’ study is to ______.
A. understand human-animal relationship
B. make lonely old people’s life better
C. find the causes of old people’s loneliness
D. promote the animal-assisted research
49. What is the advantage of AIBO over live dogs?
A. It is easier to keep at home.                    B. It can help the disabled people.
C. It responds to all the human orders          D. It can watch TV with its owner.
50. The author seems to suggest that the future robotic dogs may_____.
A. cure certain diseases
B. keep old people active
C. change people’s beliefs
D. look more like real dogs

C
Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there’s whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job's pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas:
1) Do you prefer working alone or with other people?
There are isolating(使孤立) jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.
2) How do you handle change?
Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don't happen so often. Other people would be bored of the same daily routine.
3) Do you enjoy working with computers?
I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you'll likely find a lot of positions somewhere in the middle as well.
4) What type of work environment do you enjoy? 
This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly.
5) How do you like to get paid?  
Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.
Anyway, these are a great starting point for you. I've seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better.
49．This passage mainly talks about the importance of _______.
A．different jobs      B．personalities    C．personal skills     D．job’s pay
50．Which of the following is TRUE according to the passage?
A．Isolating jobs usually drive people mad.
B．Interactive jobs make people shy easily.
C．Extreme people tend to work with others.
D．Almost everyone has a tendency in jobs.
51．What is the missing word about a job search in the following chart?
A．Design   B．Skills     C．Cooperation    D．Hobbies

B
The fiddler crab (蟹) is a living clock. It indicates the time of day by the colour of its skin, which is dark by day and pale by night. The crab’s changing colour follows a regular twenty-four hour plan that exactly matches the daily rhythm of the sun.
Does the crab actually keep time, or does its skin simply answer to the sun’s rays, changing colour according to the amount of light which strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab’s skin colour continued to change exactly on time.
This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely controlled inside the living body of the crab.
The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crab’s period of greatest darkening is exactly the time of low tide on the beach where it was caught!
40. The crab’s changing colour _______.
A. tells the crab what time it is 
B. protects the crab from the sunlight and enemies
C. keeps the crab warm            
D. is of no real use
41. When the fiddler crabs were kept in the dark, they _______.
A. did not change colour          B. changed colour more quickly
C. changed colour more slowly     D. changed colour on the same timetable
42. The crab’s colour—changing ability was probably developed _______.
A. in the process of evolution (进化)   B. over millions of years
C. by the work of biologists          D. both A and B  
43. The best title for this selection would be _______.
A. The Sun and the Tides             B. Discoveries in Biology
