1 . Sharks have lived in the world’s oceans for millions of years. A shark has a very good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food.     1    

Sharks grow slowly. About forty percent of all sharks lay eggs.     2     Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.

    3     They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too great. This protects the plants and other forms of life that exist in the oceans.

People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.     4     Shark liver oil is a popular source of vitamin(维他命).The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins.

Sharks are among the oldest animals on Earth.     5     If too many sharks in one area are killed, the group of sharks may never return to normal population levels.

A．The others give birth to their young.

B．Sharks are important for the world’s oceans.

C．This is a threat to other forms of life in the ocean.

D．Collectors pay thousands of dollars for the Jaws of a shark.

E．Sharks are valuable to us and we can make full use of them.

F．But some sharks are in danger of disappearing from Earth.

G．Sharks cat fish, other sharks, and plants that live in the ocean.

3 . Sam, a dog, was left behind in Colorado while his owners, Mr. And Mrs. Green moved to Southern California. They did not give the dog up. They found him a very nice home before they moved. They would have let Sam accompany them, but they were afraid the dog’s presence would make it difficult for them to rent a house when they reached their destination.
The Green family lived in Colorado for less than a year. Before that, they had lived in the same neighborhood in California to which they returned. So Sam had been there before, but only for a short time when he was young.
Several months after the Greens left Colorado, after they were comfortably settled back in California, they heard a scratch at the door. They couldn’t imagine who might be there. It never occurred to them that it might be Sam, because they were sure he was happily set up with his new family back in Colorado. When they opened the door, the Greens saw a dirty, tired dog with very hurting feet. The animal looked a little bit like Sam, but no one could believe that Sam could have walked 840 miles on his own. The tired dog spent the night under the family car. The next day, when he was more rested, he performed some of his old tricks. The Greens knew they had their own dog back.

5 . Science can’t explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people — half of them pet owners — while they performed 5minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松) around pets, says Allen, who thinks it may be because pets don’t judge.

A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about 11 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn’t lose any more weight than those without dogs but, say researchers, got more exercise overall — mostly with their dogs — and found it worth doing.

1. What does the text mainly discuss?

A．What pets bring to their owners?

B．How pets help people calm down?

C．People’s opinions of keeping pets.

D．Pet’s value in medical research.

2. We learn from the text that a person with heart disease has a better chance of getting well if________.

A．he has a pet companion

B．he has less stress of work

C．he often does mental arithmetic

D．he is taken care of by his family

3. According to Allen, why did the people do better with pets around when facing stressful tasks?

A．They have lower blood pressure.

B．They become more patient.

C．They are less nervous.

D．They are in higher spirits.

4. The research mentioned in the last paragraph reports that______.

A．people with dogs did more exercise

B．dogs lost the same weight as people did

C．dogs liked exercise much more than people did

D．people without dogs found the program unhelpful

6 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.

Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

1. The text mainly discusses the relationship between ________.

A．heart problems and air quality

B．heart problems and exercising

C．heart problems and smoking

D．heart problems and fatty food

7 . Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood．When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage.

We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. There isn’t a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.

I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

I had left the cage out on our back porch, and on the second day of the bird’s captivity(囚禁) my new pet’s mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

The following morning when I went to see how my captive was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity.”

Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

1. Why did the writer catch a mockingbird when he was a boy of 12?

A．He had just got a new cage.	B．He liked its beautiful feather.
C．He wanted it to sing for him.	D．He wanted a pet for a companion.

A．was frightened to death	B．ate the poisonous food its mother gave it
C．refused to eat anything	D．drank the poisonous water by mistake

3. An ornithologist probably means ______.

A．a religious person	B．a kind person
C．a schoolmaster	D．an expert in birds

4. What is the most important lesson the writer learned from the incident?

A．Freedom is very valuable to all creatures.

B．All birds put in a cage won’t live long.

C．You should keep the birds from their mother.

D．Be careful about food you give to baby birds.

When I was a child, I hoped to live in the city. I think I would be happy there. Now I am living in a city , but I miss my home in countryside. There the air is clean or the mountains are green. Unfortunately, on the development of industrialization, the environment has been polluted. Lots of studies have been shown that global warming has already become a very seriously problem. The airs we breathe in is getting dirtier and dirtier. Much rare animals are dying out . We must found ways to protect your environment. If we fail to do so , we‘ll live to regret it .
