题目列表(包括答案和解析)
How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional(横截面)view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

Comera is the only place in the world which has a whistle 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 can not 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 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 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.
49. If a person on Comera island is ill, .
A. others will phone the doctor in town
B. whistle language will pass the news to the doctor

50. From the passage we know radio and TV at that time.
A. killed the special way of speaking

51. 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
52. 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 in Comera.
C. The whistle language has been used for hundreds of years on the island, but will not be used any longer.
D. The record shows that one best whistler can be heard by others seven miles away.

Is there anything more important than health? I don’t think so.“ 1 ” wise people say. You can’t be good at your studies or work well when you are ill. If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure 2 The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that he will advise some treatment, or some medicine. 3 Speaking about doctor’s advice, I can’t help telling you a funny story.
