researchers (研究者) have announced (宣布) 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 (心脏病).
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 did not 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.

passage 24
it seems to be strange to you there is a blind spot (盲点)on the eyes. here is an interesting experiment (实验) that can make something disappear, when one eye is open.
make a card about the size of a postcard and write two english letters l and r on it, l on the left and r on the right. first, hold the card about 80 cm away and you see both the letters. then close your right eye and look at the letter r only with your left eye. and now, as you move the card slowly towards you, you’ll find the letter l disappearing. but if you move the card nearer to your face, the letter will be seen again. now do the same experiment with your left eye closed, you’ll find the letter r disappearing.共3页，当前第1页123

passage 25
different weather makes people feel different. it influences (影响) health, intelligence (智力) and feelings.
in august, it is very hot and wet in the southern part of the united states. people there have heart trouble and other kinds of health problems during this month. in the northeast and the middle west, it is very hot at some times and every cold at other times. people in these states have more heart trouble after the weather changes in february or march.
the weather can also influence intelligence. for example, in a 1983 report by scientists, iq (智商) of a group students were very high when a very strong wind came, but after the strong wind, their iq was 10% below. the wind can help people have more intelligence. very hot weather, on the other hand (另一方面), can make it lower. students in many schools of the united states often get worse on exams in the hot months of the year (july and august).
weather also has a strong influence on people’s feelings. winter may be a bad time for thin people. they usually feel cold during these months. they might feel unhappy during cold weather. but fat people may have a hard time in hot summer. at about 18c, people become stronger.
low air pressure (气压) may make people forgetful. people leave more bags on buses and in shops on low-pressure days. there are a “good weather” for word and health. people feel best at a temperature of about 18 centigrade (摄氏度).共3页，当前第2页123
