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.

A．They think science could give nature a fighting chance against both natural and man-made dangers.

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.

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.”

Everyone wants some degree of success. Many people believe that they deserve (值得)success simply because they believe that they deserve success. But there is a widespread belief that people who get on in life may be successful not because they deserve it, but because of influential (有影响的) friends or the right background. Sometimes it may just be a comforting and harmless belief, while at the other extreme it can be very destructive. I once met a brilliant young engineer who worked in a chemical plant. Because of her knowledge and experience, she should have been promoted（升职） to Production Manager. Instead, the job went to a man who was totally unsuited for the post. Everyone knew that he only got it because he was politically acceptable to his superiors (上司). This injustice discouraged the young engineer and many of her colleagues（同事）. It also meant that the factory was much less efficient than it could have been.
At the same, we should not be pessimistic (悲观的). More and more then modern world depends on having people who are in the job because they are good enough, not just because their faces fit. There is a story of a factory owner who sent for an engineer to see to a machine which would not go. He examined it, then took out a hammer and tapped, once. The machine started up immediately. When he presented his bill, the owner protested, “This can’t be right! $ 100 just for tapping（敲打） a machine with a hammer ?” The engineer wrote out a new bill: “For tapping a machine, $1; for knowing where to tap. $99.”
The engineer at the chemical plant was not promoted because _____.

A．it was politically less good for the boss to accept her than the man

B．her boss did not think she had the right qualifications for the job

C．the man who got the promotion was more experienced than she was

D．it is more difficult for a woman to get a promotion than for her male colleague

A．he hit the machine to get it started again

B．the factory owner could not have repaired it himself

C．he was charging for his knowledge and expert skills

D．he was the only person who could find out what was wrong with it

A．He quite agrees with it.

B．He doesn’t express his opinion his opinion at it.

C．He completely disagrees with it.
