Researchers have announced the result of two studies on the health effects of the drug aspirin(阿斯匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack.
The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(胆固醇) levels.
Earlier in the United States began a major aspirin study in the early 1980s. it included 22,000 healthy men doctors. All were between the ages of forty and eighty-four. More than 11,000 of the doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking.
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered from heart attacks. Ten of them died. 239 men who didn’t take aspirin suffered from heart attacks. Twenty-six of them died.
The researchers said the doctors’ study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said ,however, the result does not mean every man over the age of fifty should take aspirin. They said aspirin couldn’t help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first. The passage tells us that the new use of aspirin is___________.
A.to treat heart disease. |
B.to reduce pain while one suffers from a heart attack. |
C.to help old people to be more healthy. |
D.to reduce the chance of a heart attack in old men. |
Aspirin can help those who___________.
A.work as doctors | B.are under 40 years old |
C.are fat and smoke cigarettes | D.are older and healthy |
From the experiment we can conclude that about _________ of people who suffered from heart attacks without aspirin died.
A.7% | B.11% |
C.19% | D.44% |
What would you do if a stranger gave you some medicine and it would keep you slim or help you do well in exams? Would you take it?
Students at Shenzhen Luohu Foreign Language Middle School have learned to keep themselves safe by saying “no”. In fact, what those strangers want to give them are drugs (毒品) . Drugs are dangerous to your health!
“Because teens don't know much about drugs, they might want to try them,” said Zhang Dongsheng, the director of Shenzhen Drug Control Office.
Now, many schools arrange courses or organize some activities to help students know about drugs.
Liang, 16, was a good student before trying drugs. One day, some old friends told him it would be fun. After taking drugs only once, he found it very hard to stop. Liang began to spend all his time and money on drugs. Soon, he stopped going to school and started stealing. In the end, he was put in prison.
In China, taking drugs is becoming a big problem for teens. According to a survey, about one million people in China were using illegal drugs last year, and 72% of them were young people. Worse still, there are about10,000 drug users under 16 now.

Today Newtown is a clean place, but many years ago there were millions of rats there. The rats even attacked (攻击 ) the cats and dogs. Sometimes many of them tried to bite men or women at night. The rats were very large in size and they harmed (伤害 ) many people.
The city office ordered every one to kill rats. However, most people were lazy, so they did not kill many rats. The city office could do nothing with the citizens and could do nothing with the rats, either. Some time later, they had to pay some money for each dead rat. That made the people very happy. They at once began to kill rats. They got as many dead rats as they could. And some of them even stopped their own work to kill rats because they could get more pay. Every day a city official(官员 ) put all the dead rats together. He was very busy doing that, because sometimes a man brought hundreds of them in one day.
