two substances, both dangerous to health, act synergistically, each making the other more powerful and thereby causing worse damage than either would do alone.

Because of this interaction, the person who both smokes and drinks heavily may be at a greater risk of becoming ill than one who drinks like a fish, but never smokes or who smokes like a chimney, but never drinks. To get an idea of how this synergism may work, consider what happens when a smoker lights up a cigarette. With each puff he inhales at least 4,000 different chemicals. These include toxic hydrogen-cyanide, carbon monoxide and nitrogen-dioxide gases, and four dozen compounds such as benzo pyrene and radioactive polonium 210 . All are known as carcinogens. Most chemical vapors in tobacco smoke get deposited in the mouth, nose, throat and lungs in a coating called tar. It is in this tar that most of the cancer--inducing potential of tobacco smoke lies. Then in a scenario typical of chronic heavy drinkers--most of whom also smoke--our smoker feels thirsty and washes down that smoke coating in his mouth and throat with whisky. The alcohol in his drink is not in itself a carcinogen, but it may act as a solvent, dissolving the tar-taped tobacco poisons, and easing the transport of carcinogens across membranes.

Our smoker continues to drink. Soon he lights another cigarette and inhales deeply. Behind his embattled lungs, meanwhile, his liver has gone on full alert to save his life. The three-pound chemical factory, which cleans most toxins from the bloodstream, reacts to alcohol as a foreign substance and metabolizes 95 percent of it into other chemicals. But in turning its energy to clearing just one-half ounce of pure alcohol--the amount in a standard drink--per hour from our drinking smoker's blood, the liver's other metabolic functions suffer a sharp decrease. Poisons from tobacco smoke that otherwise would be removed from his blood within minutes are now allowed to flood his body for hours or days, depending on how much alcohol the liver must dispose of.

The person who smokes one or two packs of cigarettes a day loses on average six to eight percent of his blood's oxygen carrying capacity. If our heavy smoker's use of alcohol has led to alcoholism, he is probably malnourished. This malnourishment compounds problems he is having with insufficient oxygen. His brain cells are dying from it.

The synergistic effect of alcohol and tobacco may deliver a powerful blow to the cardiovascular system as well as the upper respiratory tract. For those prone to hypertension who drink more than two ounces of alcohol a day, high blood pressure is common and with it the increased risk of stroke and heart attack. For hypertensives who combine smoking and drinking, the risks are even greater.

Which of the following can be the best title of this passage？

A．Dead Mixer=Alcohol+ Tobacco.

B．Alcohol and Tobacco Are Dangerous to Health.

C．Tobacco Contains a Lot of Toxic Compounds.

D．Interaction of the Alcohol and Tobacco.

okers who combine exercise with nicotine gum or transdermal patches are more likely to quit than those who rely on nicotine replacement therapy alone. Sixty-eight patients at two Austrian hospitals were randomly assigned either a treatment program that included exercise or one that only used nicotine replacement therapy. After three months, 80 percent of those who exercised had quit smoking, while 52 percent of those in the group that did not exercise had quit. And those who exercised were more likely to reduce their cigarette smoking if they did not quit, the study found. They also scored better on several tests measuring respiratory health. The study was conducted at Otto Wagner Hospital and Lainz Hospital in Austria.

Based on the study, if a smoker wants to quit smoking, he'd better ______.

A．reduce his cigarette smoking gradually.

B．seek nicotine replacement therapy.

C．do exercises and take nicotine gum.

D．take tests measuring respiratory health.

ngs, George Harrison. He rose to international fame at the age of 17 as a member of the Beatles and went on to a career as a leading British film producer. (33)Musically, he defined a generation, with borrowings from Eastern music and religion. Millions of fans worldwide have been united in their grief and tributes have been paid by musicians and world leaders as diverse as Michael Jackson and Queen Elizabeth.

George Harrison was an unlikely rock star, an unassuming man, cynical about celebrity, concentrating on what mattered, the music. He'd been a heavy smoker for many years. Three years ago, he disclosed that he had cancer. He'd gone to Los Angeles for a final attempt at treatment. He died at a friend's house yesterday afternoon. In a statement, his family said, he left this world as he lived in it, conscious of God, fearless of death, and at peace.

(34)In Liverpool, the city that was the Beatles' and which they made famous, some people laid flowers for George Harrison at a statue of the Beatles. Others signed a book of condolence.

Bob Geldof said sorrowfully: I think almost uniquely possibly in music and certainly in guitar, are a guitarist's paces. (35)A11 his solos or his little licks can be hummed by practically everyone in the world. I don't think there is another guitar player can claim that.

Some months ago, just before his final illness, George Harrison undertook his last project. It was the reworking of a 1970 album entitled, "All Things Must Pass."

(30)

A．His international fame.

B．His leading status in the film industry.

C．His music style.

D．His personality.

he substance which people cannot resist in cigarettes is nicotine. When people smoke the nicotine goes directly into the blood stream and makes people feel relaxed. A smoker's body gets accustomed to the nicotine and if he stops smoking he feels nervous. Many smokers try to stop smoking but because of their dependence on nicotine they feel so uncomfortable that they often find it too hard to stop.

Another reason is that people simply enjoy smoking and what it symbolizes. Having a cigarette for many people means taking a break. For some people smoking becomes part of certain social forms, for example, the cigarette after dinner. Many people enjoy smoking because it makes their hands busy.

Many people also like the taste of tar in cigarettes. However, it is the tar that causes cancer. While governments and health experts have tried to make people give up smoking entirely, cigarette manufacturers have to keep selling them by producing cigarettes with less tar. Many people in western countries have welcomed these cigarettes since they find it difficult to stop smoking but want to reduce its risk.

Why are so many people dependent on cigarette？

A．Because they like the taste of tar.

B．Because smoking makes them feel relaxed.

C．Because smoking is funny.

D．Because smoking cures disease.
