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.

The purpose of this passage is to ______.

A. amuse readers B. tell an exciting adventure

According to what Larry said, the last wolf _______.

A. was the strongest of all B. had eaten up all the other wolves

C. ran much faster than the other wolves D. was very fat and couldn’t run fast enough

From what Larry’s friend asked at the end, we know that_______.

A. Larry’s trip was really dangerous

B. the last wolf was too fat to run

C. all the wolves had been shot by Larry

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.

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

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.

Behind our house is the start of a fascinating trail (小径). This trail is one of the old roads that wind through untold miles of forest. My 36 , Beans, and I walk the trail frequently. Normally, Beans sniffs alongside the trail to follow the smell of a deer track or 37 some cause known only to him.

Beans is a white dog, quite handsome and very 38 . He not only understands what we tell him, but also often makes sounds as if he were trying to 39 back.

One morning, we took a different route, which led us to an unfamiliar trail. I was sure this trail would eventually lead us to our familiar 40 . But, no. We seemed to be far off course. After two hours, I suddenly realized that Beans probably 41 the way home. So I urged, "Beans, take me home." He ran down a new trail. But it merely led to an intersection (岔道口) of trails.

Soon it became 42 that we were getting nowhere. I began to picture the rest of the day in the 43 without food or drink. We had walked about ten miles. But Beans seemed totally 44 . The sniffing and exploring was going well for him.

Finally, we 45 a crossroad near a highway. Lady Luck suggested I should turn left. We did and 46 reached a cottage beside a field. I knocked on the door and explained my situation to an old man. He laughed and then drove us home.

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.

D．He is socially responsible (责任).

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

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
