Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.
Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.
Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.
Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.
Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人员) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.
Critics(评论家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.
In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.
Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.Paying students who show improvement in tests __________.

Alzheimer’s disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer’s disease. It is a leading cause of death among the elderly. But Alzheimer’s disease is not confined(限于)to the aged. There may be a million or more people under the age of 65 suffering from the disease.
At one time, people suffering from the disease were said to be“getting old”.The disease was though to be a natural part of growing old, but it is now known that Alzheimer’s disease strikes young and old alike. It is an organic(器官的)disease that destroys brain cells.
Alzheimer’s disease affects the patient’s memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking. Then the patient’s memory begins to fail. He may forget dates, telephone numbers, names and plans.
As the disease progresses, the patient may not recognize family and friends. These symptoms(症状)often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.
In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.
Scientists don’t know exactly what causes Alzheimer’s disease. It may be caused by a virus(病毒).It may be caused by a poisonous substance(物质)in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.The main idea of the passage is that Alzheimer’s disease________.
| A．is a terrible part of the aging process |
| B．is an organic disease that affects young and old |
| C．can be cured by physical treatment |
| D．causes forgetfulness |
All of the following are symptoms of Alzheimer’s disease EXCEPT_________.
A. forgetfulness B. difficulty in speaking
.loss of sight D. loss of the ability to walkAccording to the passage, which of the following may be a cause of Alzheimer’s disease?

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(转基因的) trees.
Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.
Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.
Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack..
So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes(基因组).
However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.
"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.
They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.What trees are NOT the ones that scientists are planting in the US?
| A．Trees that worms can't hurt. |
| B．Trees that can protect themselves at a chemical attack. |
| C．Trees that can resist wind better. |
| D．Trees that can improve soil conditions. |
What caused the American scientists to work on special trees?
| A．They think science could give nature a fighting chance against both natural and man-made dangers. |
| B．Great numbers of trees have been lost due to attacks by viruses. |
| C．Researchers successfully introduced seeds designed to resist the virus. |
| D．Tree genomes are mapped out so scientists know how to improve trees. |
Which of the following was probably the first kind of trees being engineered?
| A．Papaya. | B．Pine. | C．Apple. | D．Poplar. |
The best title of the passage is .
| A．The improvement of environment |
| B．The side-effects of special trees |
| C．The development of special trees |
| D．the program of genetically engineered trees |

Asian athletes have had a spare time in the first two days of the World Indoor Championships in Birmingham, England. But Chinese hurdler(跨栏运动员) Liu Xiang surprised everyone by taking the bronze medal in the men's 60-meter hurdles.
Liu became the first Chinese male athlete to get a world indoor medal in the 18-year history of the championship and was the only Asian medallist this time.
"Karaoke (卡拉OK)! That's what I'm going to do. I'm going to get a big group of my friends together and sing. I love both Western and Chinese music but especially Michael Jackson," said Liu after clocking 7.52 seconds in the final to take his place on the podium (领奖台).
"Frankly speaking, I didn't think I was in the shape to win a medal," Liu said. "On my arrival here, my aim was just to fight my way into the final. After I did that, I thought I might just get into the top six. I knew British hurdler Colin Jackson was going to be here and he's the world record holder indoors and out."
"There was also Cuba's reigning (统治的) Olympic champion Anier Garcia and Allen Johnson, from the United States." It was Johnson, the reigning world outdoor champion, who was successful in 7.47 seconds with Garcia second and Jackson finished back in fifth.
Now Liu will never underestimate his chances again and is aiming for glory in Paris later this year.
"There is the World Championship outdoors in the summer and I have now got to think that I can get a medal. I can never again think that I can't get a medal," he said. Liu's success here marks his rapid transition into the senior ranks.
"The university gives me a lot of flexibility. My courses are very easy and the teachers are very helpful," said Liu.
They might have to be even more accommodating(乐于助人的) now if Liu starts taking on celebrity status, although an invite to his homecoming karaoke party may help. The first sentence "Asian athletes have had a spare time in the first two days…" means "________".
| A．Asian athletes can do things at their will in the first two days |
| B．Asian athletes haven't any achievements in the first two days |
| C．Asian athletes could match athletes from other continents |
| D．Asian athletes are tired of competing in the first two days |
The underlined sentence means "________".
| A．I was not satisfied with my performances |
| B．winning a medal can't show what I have done |
| C．I didn't think I was able to win a medal |
| D．I haven't told anyone about my achievements in the hurdles |

Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years. And indeed, cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates（碳水化合物） have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates — which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body —— dietary fat is more easily converted to body fat. Therefore, it’s more likely to stay on buttocks, thighs and bellies.
But cutting fat from your diet doesn’t necessarily mean your body won’t store fat. For example, between nonfat and regular cookies, there’s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight again. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn’t losing weight. Then he showed his food diary to his coach and revealed he’d been eating half a pound of jelly beans a day. “They don’t have any fat,” he explains. But they had enough sugar to keep him from shedding an ounce.
Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt（酵母乳）that contained exactly the same amount of calories. One group’s yogurt label said “high fat”—the other, “low fat.” The “low fat” yogurt group ate significantly more calories later in the day than the other group. “People think they’ve saved fat and can indulge themselves later in the day with no adverse consequences,” says Richard Mattes, a nutrition researcher at Purdue University. “But when they do that, they don’t compensate very precisely, and they often end up overdoing it.”What lessons did the computer programme learn ?
| A．Overeating will cause weight gain |
| B．He can eat half a pound of jellybeans a day |
| C．He can’t didn’t eat any fat |
| D．His coach gave him a lecture |
