Once an Englishman named Larry Belmont went to Russia for a holiday. After he got back some of his friends came. “I had a very dangerous trip while I was in Russia.” Larry said, “I went to see a friend in the country and when the sun went down, I was still traveling through a forest in a sleigh(雪橇). It was a long way from my friend’s house when about twenty wolves began to follow my sleigh.”

“It was very dark in the forest. There was thick snow on the ground. First I heard the wolves. The noise was terrible! Then I saw long, grey forms among the trees, and soon the wolves were near me. They were running very fast, and they didn’t seem to get tired like the horses.”

“What did you do?” one of Larry’s friends asked.

“When the wolves got very near,” Larry answered, “I put up my gun and shot the first wolf dead. Then all the other wolves stopped and ate it, so my sleigh got away from them for a few minutes. Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another one of them, and the others stopped once more to eat it. The same thing happened again, and my horses become more and more tired and ran slower and slower until, after two hours, only one wolf was still alive and following me.”

“Wasn’t it too fat to run?” one of Larry’s friends asked.

D. the friend did not believe what Larry had said

All across California, honeybees are flying away from their hives(蜂箱) and dying. Empty hives are causing a lot of worry about some important food crops.

Bees give us a lot more than delicious honey. They are pollinators（授粉者）—they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds. In the U.S., millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops. “Bees are worth protecting because their work adds so much to our diet,” says Dr. Jeff Pettis of the Bee Research Laboratory.

California’s almond (杏仁) crop alone depends on about half the bees in the country. But now the almond crop and many others could be in trouble with so many bees dying.

Researchers at government and university labs all over the country are trying to figure out why so many bees are dying. However, bees are hard to study. Most die away from the hive, so researchers don’t have dead bodies to examine. And when researchers return to a hive after two weeks, about half the bees they studied on their first visit will be dead, replaced by new ones in the natural life cycle of bees. “It isn’t like studying a large animal like a cow that doesn’t move around much and is easy to find out in the cow field,” says Pettis.

Researchers have some ideas about what could be affecting bee health. They could be sick from poisons widely used to kill insects, or they might not be getting enough good food to stay strong. Also, tiny insects called mites feed on bees. “A virus or bacteria could also be doing the killing.” explains Pettis.

1.What is Paragraph 2 mainly about?

A. The wind helps pollinate.

B. Bees are important in food crops.

C. Bees give us a lot of delicious honey.

D. Cherry trees are pollinated by bees.

2.Bees are hard to study because ____________.

A. they move around too much

B. new bees soon replace all the bees studied by researchers

C. they are too tiny

D. they never return to hives

3.What could cause so many bees to die?

A. Poisons to kill birds.                                                               B. Eating too much.

C. Large insects.                                                                          D. Some virus.

4.What can we learn from the article?

A. A large number of bees have died in the hive.

B. Without bees, some foods would disappear from our diet.

C. Only researchers in California want to know what kills bees.

D. Large animals are easier to study than tiny insects.

I come from a city on the United States’east coast. It’s a ten-hour flight for me to get home from Shanghai. When I got off the plane, I took photos of the blue sky and white clouds along the way. After two weeks, I returned to Shanghai. Much to my surprise, the blue sky in Shanghai that I liked before was not as blue as that in the US. I couldn’t help wondering what had happened.

A few days later, I went to tour Waitan (a famous tourist attraction in Shanghai) by the Huangpu River with some of my friends. There we saw five Ferrari sports cars by the side of the road. The red and yellow cars looked so nice that everyone was looking at them. However, when I turned my head, I noticed the sky over Waitan, I was shocked to find that the buildings in the Lujiazui area on the other side of Huangpu River could hardly be seen. It was then that I realized that Ferrari cars could be bought with money, but a blue sky couldn’t.

Shanghai is an important economic (经济的) and trade center in China. It has made great contributions (贡献) to the whole nation’s economic development. However, we need to protect the environment during economic growth. Pollution is poisoning our air and our rivers. Without clean air and rivers, how will people be able to survive?

1.The author mentioned the Ferrari sports cars in order to _______.

A．tell us that Shanghai is a developed city

B．ask us to stop driving sports cars

C．tell us how much people like cars

D．focus our attention on air pollution

2.What can we learn about the author?

A．He comes from Shanghai.

B．He likes to visit different places.

C．He wants to buy a Ferrari sports car.

A．Those who love Ferrari sports cars.

B．Those who care about the environment.

C．Those who want to travel in Shanghai.

D．Those who like to take photos.

4.What is the best title for this passage?

A．Money Can Buy Ferraris, But Not a Blue Sky

B．Where People Should Live

C．Different Opinions on Cars

D．Different Places Have Different Skies

 

Dr. Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind. But he had no idea at the time that 12 - year – old Ray had the ability to become his partner in cancer research.

Ray’s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner（吸尘器）. When he was ten, he speedily constructed the family color television from a kit. Later, he succeeded in assembling（组装） a complex stereo system after two experts had failed to do the job.

When Ray was ten, he convinced his parents to buy him a computer. In a short time, Ray was able to do amazing things with the computer. Ray shared his enthusiasm for computers with Dr. Tisman, who used a computer for his research. The two discussed computers and medicine frequently. Amazingly, Ray understood the biology and chemistry related to Dr. Tisman’s medical research without any previous instruction.

Ray then worked with Dr. Tisman after school. He helped conduct research with the equipment and kept it in working order. The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins. Ray analyzed patient test results by computer, while Dr. Tisman handled all patient contact. Together, they came up with solid research that helped advance cancer treatment.

In 1988, 14 - year - old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical Research（AFCR）, where Ray presented their initial research findings. Using terminology（术语） beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients.

A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman’s research. By then, he had become well - known for his devotion to finding cures for sick patients. Stories about him appeared in hundred of newspapers around the world. He appeared on television newscasts and talk shows.

Ray continued to spend most free hours working with Dr. Tisman. The two began studying the effects of vitamins on babies inside the womb（子宫）. However, Ray’s main interest remained cancer treatment, and he continues his research today.

1.According to the passage, Ray______.

A. is a boy of many gifts                                      

B. is very helpful to his parents

C. learned fast under Dr. Tisman’s instruction

D. stopped working with Dr. Tisman after his success

2.What do we know about Dr. Tisman?

A. He succeeded in finding cures for cancer.

B. He made a new discovery in cancer treatment.

C. He convinced Ray to become a partner of him.

D. He taught Ray knowledge related to his research.

3.What made Ray first known to the medical world?

A. His presentation at AFCR.             B. His great skills in computer.

C. His devotion to cancer research.      D. His appearance on television newscasts.

4. Dr. Tisman’s research is aimed at ______.

A. providing different cancer treatments

B. proving the effects of vitamins on babies

C. finding the side effects of a cancer drug

D. testing the effectiveness of a new drug mixture
