Passage 2 Questions 6 to 10 are based on the following passage: Onthejob smoking is a hot issue for both smokers and nonsmokers, and many managers now see smoking as a productivity problem. Although some people question whether smoking really affects one’s productivity, it has, in fact, been proven that a smoker costs a company more than a nonsmoker. According to Professor William Weis, a smoking employee costs his or her employer about $ 5,700 more a year than a neversmoker. These costs include medical care, lost earnings and insurance. And absence due to smoking breaks is one of the productivity problems, yet it accounts for a great deal of employer costs. (78) When the issue of smoking at the workplace is discussed, perhaps the most important problem is the health risk that smoking causes to both smokers and neversmokers. It has long been proven that smoking is linked to lung cancer. Now many health experts warn that passive smoking can cause lung cancer and other illnesses in healthy neversmokers. Passive smoking can be defined as exposure to secondhand tobacco smoke in enclosed areas. Anyone who has been with smokers indeed knows that their smoke can cause eye irritation, coughing, headaches and throat soreness. While eye irritation may seem a small thing to some smokers, it nevertheless is a problem that occurs every workday in offices and breakrooms and can lead to greater health problems. Employees who do not smoke should not be subjected to the risks of passive smoking and need to be able to work in a safe environment. Surgeon General Koop states that the right of the smoker stops at the point where his or her smoking increases the disease risk of those occupying the same environment. All the following cases are onthejob smoking except that____.

A. an employer smokes while working in the office
B. a taxi driver smokes while driving the car
C. a worker smokes while working in the workshop
D. a worker smokes while reading in the train

Passage 1 Questions 1 to 5 are based on the following passage: Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares(噩梦). (76)Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase(抹去), the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. (77) So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories. “Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions.” said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.” But those who are against the research say that it is very dangerous to change memories because memories give us our identity. They also help us all avoid the mistakes of the past. “All of us can think of bad events in our lived that were horrible at the time but make us who we are. I’m not sure we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist. The word “scars” in Paragraph One is close in meaning to ____.

A. good stories
B. pains
C. experiences
D. memories
