阅读下面短文，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。
Is there anything more important than health? I don’t think so. “Health is the greatest wealth,” 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, I think you should go to the doctor.
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. The only thing you have to do is to follow his advice.
Speaking about doctor’s advice, I can’t help telling you a funny story.
An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease.
He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat at pleasure, drink with measure and enjoy life as it is.” The doctor also said that if the man wanted t be well again, he shouldn’t smoke more than one cigarette a day.
A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.
“But you know, doctor,” he said, “ it’s not easy to begin smoking at my age.”

The Antarctic is actually a desert. It’s the only continent on the earth without a river or lake.
The Antarctic is all ice all year round. The warmest temperature ever recorded there is zero, at the South Pole. Explorers used to think that a place so cold would have a heavy snowfall. But less than ten inches of snow falls each year. That is less than half an inch of water. The times that much water falls in parts of the Sahara.
The little snow that falls never melts. It continues to pile up deeper and deeper year after year and century after century. When the snow gets to be about 80 feet deep it is turned to ice by the weight of the snow above it.

IN THE BEDROOM
Don’t smoke in bed ------it causes 1000 fires a year, many with fatal (致命的)results.
Don’t overload your electrical points: the right way is “one appliance（电器）, one socket”（插座）.
Don’t use an electric underblanket over you or an overblanket under you. An underblanket , unless of the low- voltage type, MUST be switched off before you get into bed.
Never let furniture or clothing get close to a lighted fire. Make sure that there is a suitable guard for the room heater.
Keep aerosol-type containers （喷雾器）away from heat and NEVER burn or puncture（刺穿）them.
Don’t dim a table lamp by covering it: buy a low-wattage bulb（灯泡）.
Pajamas （睡衣）and nightdresses, especially for children and elderly people, should be made from flame- resistant material.
IF CUT OFF　BY FIRE
Close the door of the room and any fanlight or other opening and block up any cracks （缝隙）with bedding, etc.
Go to the window and try to attract attention.
If the room fills with smoke, lean out of the window unless prevented by smoke and flame coming from a room below or nearby. If you cannot lean out of the window, lie close to the floor where the air is clearer until you hear the fire brigade（队）.
If you have to escape before the fire brigade arrives, make a rope by knotting together sheets or similar materials and tie it to a bed or another heavy piece of furniture.
If you cannot make a rope and the situation becomes intolerable（难耐的），drop cushions or bedding from the window to break your fall, get through the window feet first, lower yourself to the full extent of your arms and drop.
If possible drop from a position above soft earth. If above the first floor, drop only as a last resort.

On October 12, 1989, some Chinese scientists were working at the computers to look for information they needed. Suddenly they saw a lot of very bright spots crossing the computers’ screens. At the same time, the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses! Obviously all these computers had been infected （传染）by computer viruses.
It is said that the computer viruses were made by a group of young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. These kinds of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the function, damaging their normal programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers.
