During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.
Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.

考题 Passage FourEvery culture and every country in the world celebrates New Year, but not everyone does it the same way. The countries in North America and Europe welcome New Year on January the first. This practice began with the Romans in the Middle East, New Year is when spring begins. People in China and Vietnam celebrate it on the first day of the Spring Festival, which is the first day of their calendar based on the moon. Rosh Hashana, which is the Jewish (犹太人的) New Year, comes at the end of summer. The Hindus (印度教教徒 ) in India celebrate the first day of each season, so they have four New Years.In all these cultures, there is a practice of making noise. People made noise in ancient times to drive away the evil spirits (妖精) from their homes. Today making noise is more of a custom than a religious rimIn the United States, many people stay up until midnight on New Year's Eve to watch the clock pass from one year to the next. Friends often gather together at a party on New Year's Eve, and when the new year comes, all ring bells, blow' whistles, sing songs, and kiss each other. A favorite Scottish song which everyone sings together is Auld Lang Sync. The words tell of old friends and good times.In all cultures, New Year's Day is a time when people think of new beginnings. They want to make the coming year better than the last one. Many people in the United States make New Year resolutions. These are specific promises that they make to improve their behavior, change their habits, and become better people. There are many jokes about how a person keeps his or her New Year resolutions.48. In ancient times, the practice of making noise was meant ______.A. to keep the evil spirits awayB. to have funC. to celebrate the coming of the new yearD. to keep to a custom

考题 People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular. Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco bums, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person′s breathing muscles. Smokers usually take in small amounts that the body can quickly break down. Nicotine can make new smokers feel dizzy (头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers′ risk of heart disease and stroke. Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases. Tobacco first appeared in ___________.A.Asia B.Africa C.Europe D.America

考题 Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled--to $1.01 per pack--smokers have jammed telephone "quit lines" across the country seeking to kick the habit. This is not a surprise to public health advocates. They've studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase. The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely. In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drug store Wednesday. Charleston, S.C, where the 7-cent-a-pack tax is the lowest in the nation. The price was $4.78.The influence is obvious. In New York, high school smoking hit a new low in the latest surveys--13.8%, far below the national average. By comparison,26% of high school students smoke in Kentucky, Other low-tax states have similarly depressing teen-smoking records. Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans "who choose to smoke." That's true. But there is more reason in keeping future generations of low-income workers from getting hooked in the first place, as for today's adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better. The underlined word "deter" in paragraph 3 most probably means_________.A. discarding B. remove C. benefit D. free

An estimated 1.25 billion people smoke worldwide.Yet people who are depressed or anxious are twice as likely to smoke,and up to 88 percent of those with psychotic disorders such as schizophrenia are smokers.A recent American survey concluded that around half of all cigarettes burn in the fingers of those with mental illness.4.But the big question is why?The usual story is that the illness comes first. Mentally ill people take up smoking,or smoke more,to alleviate some of their distress.Even when smoking seems to start before the illness,most doctors believe that early but invisible symptoms of the disorder spark the desire to light up.But perhaps something more sinister is going on.5.A growing number of researchers claim that smoking is the cause,not the consequence of clinical depression and several forms of anxiety."We know a lot about the effects of smoking on physical health,and now we are also starting to see the adverse effects in new research on mental illness,"says Naomi Breslau,director of research at the Henry Ford Health Care System in Detroit.6.Breslau was one of the first to consider this heretical possibility.The hint came from studies, published in 1998,which followed a group of just over 1.,000 young adults for a five-year period.The 13 percent who began the study with major depression were around three times more likely to progress from being light smokers to daily smokers during the course of the study,though there was no evidence that depression increased the tendency to take up smoking. But a history of daily smok-- ing before the study commenced roughly doubled the risk of developing major depression during the five-year period. Smoking,it seems,could pre-date illness.7.At first Breslau concluded that whatever prompts people to smoke might also make them depressed.But as the results of other much larger studies began to back the statistical link,she became more convinced than ever that what she was seeing were signs that smoking,perhaps the nicotine itself,could somehow affect the brain and cause depression.8.One of these larger studies was led by Goodman,a pediatrician.She followed the health of two groups of teenagers for a year. The first group of 8,704 adolescents were not depressed,and might or might not have been smokers,while the second group of 6,947 were highly depressed and had not been smokers in the past month.After a year her team found that although depressed teenagers were more likely to have become heavy smokers,previous experimentation with smoking was the strongest predictor of such behaviour,not the depression itself. What is more important is that teenagers who started out mentally fit but smoked at least one packet per week during the study were four times more likely to develop depression than their non一smoking peers.Goodman says that depression does not seem to start before cigarette use among teens."Current cigarette use is,however,a powerful determinant of developing high depressive symptoms."9.Breslau,too,finds that smokers are as much as four times more likely to have an isolated panic attack and three times more likely to develop longer-term panic disorder than non-smokers.It's a hard message to get across,because many smokers say they become anxious when they quit,not when they smoke.But Breslau says thatBreslau's study________than Goodman's but lasted longer.A:have been proved to be misleadingB:but to their mental health as wellC:taking up smokingD:involved fewer peopleE:they started to smoke at an early ageF: but their level of anxiety increases when they quit smoking

Smoking,it seems,could pre-date illness.7.At first Breslau concluded that whatever prompts people to smoke might also make them depressed.But as the results of other much larger studies began to back the statistical link,she became more convinced than ever that what she was seeing were signs that smoking,perhaps the nicotine itself,could somehow affect the brain and cause depression.8.One of these larger studies was led by Goodman,a pediatrician.She followed the health of two groups of teenagers for a year. The first group of 8,704 adolescents were not depressed,and might or might not have been smokers,while the second group of 6,947 were highly depressed and had not been smokers in the past month.After a year her team found that although depressed teenagers were more likely to have become heavy smokers,previous experimentation with smoking was the strongest predictor of such behaviour,not the depression itself. What is more important is that teenagers who started out mentally fit but smoked at least one packet per week during the study were four times more likely to develop depression than their non一smoking peers.Goodman says that depression does not seem to start before cigarette use among teens."Current cigarette use is,however,a powerful determinant of developing high depressive symptoms."9.Breslau,too,finds that smokers are as much as four times more likely to have an isolated panic attack and three times more likely to develop longer-term panic disorder than non-smokers.It's a hard message to get across,because many smokers say they become anxious when they quit,not when they smoke.But Breslau says thatTo contradict Breslau's conclusion,many smokers say that they are less anxious when they smoke________.A:have been proved to be misleadingB:but to their mental health as wellC:taking up smokingD:involved fewer peopleE:they started to smoke at an early ageF: but their level of anxiety increases when they quit smoking

考题 共用题干 The Dangers of Secondhand SmokeMost people know that cigarette smoking is harmful to their health.Scientific research shows that it causes many kinds of diseases.In fact,many people who smoke get lung cancer. However,Edward Gilson has lung cancer,and he has never smoked cigarettes.He lives with his wife Evelyn,who has smoked about a pack of cigarettes a day throughout their marriage.________(46)No one knows for sure why Mr. Gilson has lung cancer. Nevertheless,doctors believe that secondhand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people's cigarettes.________(47)The US Environmental Protection Agency reports that about 53,000 people die in the United States each year as a result of exposure to secondhand smoke.The smoke that comes from a lit cigarette contains many different poisonous chemicals.In the past, scientists did not think that these chemicals could harm a nonsmoker's health._________(48)They discovered that even nonsmokers had unhealthy amounts of these toxic chemicals in their bodies.As a matter of fact,almost all of us breathe tobacco smoke at times,whether we realize it or not. For example,we can not avoid secondhand smoke in restaurants,hotels and other public places.Even though many public places have nonsmoking areas,smoke flows in from the areas where smoking is permitted.It is even harder for children to avoid secondhand smoke._________(49)Research shows that chil- dren who are exposed to secondhand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as are children of nonsmokers.The risk is even higher for children who live in homes where both parents smoke.People are becoming very aware of the dangers of secondhand smoke._________（50)__________（50）A:Recently,though,scientists changed their opinion after they studied a large group of nonsmokers.B:The Gilsons have been married for 35 years.C:This smoke is called secondhand smoke.D:However,secondhand smoke is dangerous to all people,old or young.E:As a result,they have passed laws which prohibit people from smoking in many public places.F: In the United States,nine million children under the age of five live in homes with at least one smoker.

考题 单选题Advertisement: The most flavorful olives in the world are kalamata olives. The more kalamata olives used to make a bottle of olive oil, the more flavorful the oil, and no company buys more kalamata olives than Zorba’s Olive Oil. Therefore, when you buy Zorba’s Olive Oil, you’re buying the most flavorful olive oil available today.　 The reasoning presented in the advertisement is flawed because it overlooks the possibility that:A Not all of Zorba’s competitors use kalamata olives in their oil.B Zorba’s sells more olive oil than any other company.C The most flavorful olive oil is not necessarily the best olive oil.D Because of bulk discounts, Zorba’s pays less per kilogram of kalamata olives than does its competitors.E The number of kalamata olives harvested every year is far less than the number of Spanish olives harvested every year.
