Comera is the only place in the world which has a whistle(口哨)language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley cannot easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.
We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of the telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.
The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera island you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions. If a person on Comera island is ill, .
| A．others will phone the doctor in town |
| B．the whistle language will pass the news to the doctor |
| C．his family will take him to the doctor |
| D．people will take him to the hospital |

| A．killed the special ways of speaking |
| B．whistled all the news and opinions |
| C．helped Comera people to communicate |
| D．did not appear on Comera island yet |
Comera island is special in that .
| A．it attracts visitors every year |
| B．no visitors have ever been there |
| C．people there have special ears to hear whistles |
| D．people there use the whistle language to communicate with each other |
Which of the following is NOT true according to the passage?
| A．It is not easy for a person to live on Comera island if he cannot whistle. |
| B．The whistle language can only be found on Comera island. |
| C．The whistle language has been used for hundreds of years on the island, but will not be used any longer. |

The disease asthma affects as many as one hundred fifty million people around the world. It is a serious lung disease that causes breathing problems. These problems, called asthma attacks, can kill people. Asthma can affect people of all age groups but often begins in childhood. It can be controlled but not cured. Sufferers must deal with the disease every day.
Experts say exercise is one of the things that can start an asthma attacks. Things that lead to asthma attacks are called triggers. Although doctors do not know the cause of asthma, they have identified(辨认)most of its triggers. For example, the common cold can cause an asthma attack in a person who has the disease. There are also several air pollutants(污染物)that can lead to an asthma attack. Pollen is one such pollutant. Pollen is a fine dust that comes from plants that produce seeds. However, almost any kind of dust can cause an asthma attack if enough of it is in the air. This includes common dust found in houses.
Air pollution from burning fuel also can cause an asthma attack. Tobacco smoke can do the same. Some kinds of animal fur are a trigger for asthma. And, even some insects(昆虫)in the home can lead to asthma attacks.
Several things happen in the lungs when an asthma sufferer has an attack. Cells in the air passages begin to produce too much of a thick, sticky material called mucous(痰). The mucous creates blocked areas in the air passages. The tissue(组织)that lines the air passages begins to expand at the same time. And, the muscles in the passages tighten.
All these changes cause the air passages to narrow. This reduces the amount of air that can flow in and out of the lungs. The sufferer can not get a good, deep, breath of air. The narrowed airways also cause coughing and a tight feeling in the chest.Which of the following statements about the disease asthma is NOT right?
| A．It causes breathing problems, which can have sufferers killed. |
| B．It can not be cured but can be controlled. |
| C．People of all age groups can get affected, especially the old. |

| D．The disease asthma, caused by mucous, can be prevented. |
Have you ever sat on a camel? Well, if you have, then you know how scary it is when the camel rises on its long wobbly(摆动的)legs. The rocking motion of a camel is a bit like a being tossed around in heaving seas. Small wonder then that the camel is often called the ship of the desert. Actually, the name owes its origins to the fact that camels were brought from the desert, to serve as beasts of burden in other countries.
We in India are only familiar with one species of camel, known as the Dromedary camel. This animal is singlehumped, has long legs and is found in the deserts of Asia and Africa. Another specie(the twohumped shortedlegged Bactrian camel)is found in parts of China and Central Asia.
Recently, scientists discovered what they think is a new species of wild camel that lives in a remote part of China. These mammals look very similar to the Bactrian camel but they have a unique feature—they survive by drinking salty water.
Strangely enough, scientists knew about the existence of the animal, but had no idea of their unique identity(特性). As a result, researchers now admit that these animals are not Bactrian camels as initially(最初)thought, but a new species. The only visible physical difference is that the saltwater drinking species has its humps further apart than the Bactrian camel.
Camels are most common in the African and Asian deserts, but fossil evidence shows that camels originated in North America about 45 million years ago. So how did they manage to come into Africa? Well, million of years ago, North America and Asia were connected by a land mass—the presentday Bering Strait.
Scientists think that the camels migrated into South America and across to Asia, disappearing almost entirely from the land of its origin. However, many researchers say that the South American llama(骆驼)is a direct descendant of the camel.The camel is called“the ship of the desert”because________.
| A．when you are on a camel, you feel like being on a ship at sea |
| B．its long legs swung when it is traveling in the desert |
| C．camels came from the desert and are used in other countries |
| D．camels can travel in the desert of many days without eating |
What's the difference between the Dromedary camel and the Bactrian camel?
| A．The Dromedary camel has two humps. |
| B．The Bactrian camel has long legs. |
| C．The Dromedary camel is only found in Asia. |
| D．The Dromedary camel has only one hump. |
What scientists don't know about the new species is________.
| A．their existence in China |
| B．their ability to survive on salty water |
| C．their similarity to the Bactrian water |
| D．how they survive in the remote part of China |
How can people tell the new species from the the Bactrian camel?
| A．By looking at the length of their legs. |
| B．By counting the number of humps. |
| C．By looking at the distance of the two humps. |
| D．By examining the kind of the two humps. |
From the passage we can infer that________.
| A．Very few camels exist in North America at present |
| B．Camels warm across the Bering Strait to Asia |
| C．Camels first originated from the African deserts |
| D．Camels are the most endangered animals in the world |

The cost of medical care in the United States is very high. The time and money that doctors spend on their medical education is probably one reason for this problem.
A visit to a doctor's office costs from fifteen to fifty dollars. It is almost impossible for people to pay for medical care they need. Many people in the United States think that doctors are overpaid. Most doctors, however, disagree. They say that they have been required to study medicine for a long time. Tuition(学费)for many years of medical education costs lots of money. Doctors say that it is necessary for most medical students to borrow money from a bank to pay their tuition. Because this money must be repaid to the bank, young doctors need to receive a lot of money for their work. So they charge(收费)people high prices for medical care.
Therefore, it's possible that the high cost of medical care in America is unnecessary. Because high tuition is one cause of high costs, one way to lower costs would be to have medical schools that are free or have low tuition.Some people don't have their medical care they need because________.
| A．they are not willing to pay the doctors high tuition |

Parents often believe that they have a good relationship with their teenagers(青少年). But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his firends than to his parents.“The door to his room is always shut，”Joanna noted.
Tina and Mark noticed similar changes in their 14yearold daughter. “She used to cuddle up(蜷伏)with me on the sofa and talk，”said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what's on their minds. “In fact, parents are first on the list，”said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years，”Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.“The door to his room is always shut”suggests that the son________.
| A．is always busy with his studies |
| B．doesn't want to be disturbed |

| A．Teenagers talk a lot with their friends. |
| B．Teenagers do not want to understand their parents. |
