B
　　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(膽固醇) 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.

　　Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
　　The eye-recognition(眼睛識別) programme is already being tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon, this technology will take the place of all other ways of finding out who people are.
　　However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
　　Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94% correct, depending on(依靠) how good the technology is. Some programmes may only be right 51% of the time. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
　　In the future your computure will be looking at you in the eye. So smile!
　　32. How does the eye-recognition programme work?
　　A. You write your number.        B. You show your ID card.
　　C. You look at the machine.       D. You say your name.
　　33. Why can the programme be up to 94% correct?
　　A. Because eyes never change.     B. Because hands or fingers can get dirty.
　　C. Because people like the idea of the programme.
　　D. Because the programme is widely used around the world.
　　34. Which of the following is TRUE?
　　A. The programme is being tested in Japan.
　　B. Machines with other systems can also tell who you are.
　　C. 91% people like the idea of the programme.
　　D. Computers can remember you by looking at your clothes.
