While some teenagers may use cigarettes to "self-medicate"(自我治疗)against the blues(忧郁),sci-
entists at the University of Toronto and the University of Montreal have found that smoking may actually
______________
(51)depressive symptoms in some teens.
"This observational study is one of the few to examine the perceived ______________(52)benefits of
smoking among teens,"says lead researcher Michael Chaiton,a research associate at the Ontario Tobacco
Research Unit of the University of Toronto."_______________(53)cigarettes may appear to have self-medicating

参考答案

参考解析
解析:由前后两句的转折关系可知,抽烟不是减轻忧郁,而是加重(increase)了忧郁的症状。
由第五段的最后一句话中的“emotional benefits”可知选emotional合适。
由前后两句语境可知此处表示转折关系,四个关联词只有B项合适。
in the long term意为“长期”,为固定搭配。
抽烟只能影响(affect)情绪,而不是其他的反应。
schools located意为“学校坐落在……”,其他选项不符合句意。
由下文可知,参加者是被分成三组(groups)。
mood or physical state意为“精神或身体状况”,为常用搭配。
have trouble doing sth.意为“做……有困难”,为固定短语。
mood improver意为“情绪改善者”,符合语境。
由前面的“higher”可知此处是比较级,所以用than。
at risk为固定词组,意为“有风险”;at higher risk意为“有更大的风险”。
在忧郁和抽烟之间只有“联系”(association),而不是“合作”、“不同”与“一致”。
这种抽烟和忧郁的联系主要存在于抽烟感觉好的青少年中,由句意知选B。
由动词不定式后面强调的内容可知,此处是强调其重要性,所以选A。

考题 The human can react to any situation, some of which he may never have imagined.()

考题 In has been shown that children who smoke have certain characteristics.Compared with non-smokers they are more rebellious, their work deteriorates as they move up school, they are more likely to leave school early, and are more often delinquent and sexually precocious.Many of these features can be summarized as anticipation of adulthood.There are a number of factors which determine the onset of smoking, and these are largely psychological and social.They include availability of cigarettes, curiosity, rebelliousness, appearing tough, anticipation of adulthood, social confidence, the example of parents and teachers, and smoking by friends and older brothers and sisters.It should be much easier to prevent children from starting to smoke than to persuade adults to give up the habit once established, but in fact this has proved very difficult.The example set by people in authority, especially parents, health care workers, and teachers, is of prime importance.School rules should forbid smoking by children on the premises.This rule has been introduced at Summerhill School where I spent my schooldays.There is, however, a risk of children smoking just to rebel against the rules, and even in those schools which have tried to enforce no smoking by corporal punishment there is as much smoking as in other schools.Nevertheless, banning smoking is probably on balance beneficial.Teachers too should not smoke on school premises, at least not in front of children1、Which of the following is a common characteristic of young smokers?A、DisobedienceB、LazinessC、Lack of intelligenceD、Vanity2、Which of the following is NOT true according to the passage?A、Some children start to smoke out of curiosityB、Many children start to smoke because they want to appear mature.C、In order to have fewer children smokers, parents, teachers and health care workers should not smoke.D、It is not as difficult to prevent children from starting to smoke as to dissuade adults from smoking.3、The writer concludes that school rules to forbid smoking().A、should be introduced, for it really works at the school where he once studied.B、should not be introduced, for it may cause disturbance.C、should be introduced though it may not work effectively.D、needn't be introduced as long as teachers don't smoke in front of children.4、The author's attitude towards his writing is().A、objectiveB、emotionalC、criticalD、indifferent

考题 共用题干 第一篇UlcersEven though ulcers appear to run in families,lifestyle plays more of a role than genetic (基因的)factors in causing the illness, according to a report in the April 13th issue of Journal of Internal Medicine. In particular,smoking and stress in men and the regular use of pain-releasing medicines in women were linked with an increased risk of developing an ulcer(溃疡).Overall,61% of ulcer risk appears to be due to environmental factors,such as smoking,and the remaining 39% is due to genes,according to Dr. lsmo Raiha of the University of Turkey and colleagues at the University of Helsinki,Finland.Some researchers had suggested that families may spread Helicobacteria pyloni(幽门螺旋菌), the bacteria(细菌)that can cause ulcers. However, the new study suggests this is unlikely,according to the report.Raiha and colleagues studied data from more than 13,000 pairs of twins to examine the roles of genetic and environmental factors in the origin of ulcer. Both twins were more likely to develop an ulcer if the pain were genetically the same as compared with a pair of fraternal(由两受精卵发育而成的)twins , suggesting that there must be some genetic susceptibility(敏感性)to ulcer development.However,the risk was no greater in twins living together compared with twins living apart,suggesting that shared exposure to H.pyloni was not to blame." Environmental effects were not due to factons shared by family members,and they were related to smoking and stress in men and the use of pain-releasing medicines in women,"the authors write in their report. In the last paragraph,the word"suggesting"could be best replaced byA:assuming. B:implying.C:proposing. D:believing.

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. What is the main purpose of the first paragraph?A.To tell us the bad effects caused by smoking cigarettes. B.To introduce the history of smoking. C.To let us know what the cigarettes are made from. D.To tell the readers that Columbus found the Indians smoking.

But add to that list a frightening new concern一mental illness.According to some controversial new findings,if smoking does not kill you,it may,quite literally,drive you to despair.2.The tobacco industry openly pushes its product as something to lift your mood and soothe anxiety.But the short-term feel-good effect may mask the truth that smoking may worsen or even trigger anxiety disorders,panic attacks and depression,perhaps even schizophrenia.3.Cigarettes and mental illness have always tended to go together. 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

考题 共用题干 Cigars Instead?Smoking one or two cigars a day doubles the risk of cancers of the lip,tongue,mouth,and throat,according to a government study.Daily cigars also increase the risk of lung cancer and cancer of the esophagus,and increase the risk of cancer of the larynx(voice box)sixfold,say researchers at the National Cancer Institu- te in Bethesda,Maryland. In addition,the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers.The health effects of smoking cigars is one of eight sections of the article"Cigars:HealthEffects and Trends".The researchers report that,compared with a cigarette,a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines."This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country,"said Dr. Richard Klausner, director of the National Cancer Institute,in a statement."The data are clear-the harmful substances and carcinogens in cigar smoke,like cigarettes,are associated with the increased risks of several kinds of cancers as well as heart and lung diseases,"he added."In other words,cigars are not safe alternatives to cigarettes and may be addictive.""To those individuals who may be thinking about smoking cigars,our advice is-don't. To those currently smoking cigars,quitting is the only way to eliminate completely the cancer,heart and lung disease risks,"warned Klausner.According to a National Cancer Institute press release,there haven't been any studies on the health effects on nonsmokers at cigar social events,but“... a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke." What is the main idea of the article"Cigars:Health Effects and Trends"?A: When it comes to cancer,cigars are not any safer than cigarettes.B: Cigars may be addictive while cigarettes are not easily so.C: Cigars contain less harmful substances than cigarettes.D: Increase in cigar-smoking does not affect public health much.

考题 共用题干 New Research Lights the Way to Super-fast Computers1. New research published today in the journal Nature Coniniunications,has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.2. The research by the University of Surrey,in collaboration with the University of Cambridge and the University of Southampton,has found it is possible to change the electronic properties of amorphous chalcogenides,a glass material integral to data technologies such as CDs and DVDs. By using a technique called ion doping,the team of researchers have discovered a material that could use light to bring together different computing functions into one component,leading to all-optical systems.3. Computers currently use electrons to transfer information and process applications.On the other hand,data sources such as the Internet rely on optical systems:the transfer of information using light. Optical fibres are used to send information around the world at the speed of light,but these signals then have to be converted to electrical signal once they reach a computer,causing a significant slowdown in processing.4 .“The challenge is to find a single material that can effectively use and control light to carry information around a computer. Much like how the web uses light to deliver information,we want to use light to both deliver and process computer data,”said project leader,Dr. Richard Curry of the University of Surrey.5 .“This has eluded researchers for decades,but now we have shown how a widely used glass Call be manipulated to conduct negative electrons,as well as positive charges,creating what are known as‘pn-junction'devices. This should enable the material to act as a light source,a light guide and a light detecto—something that can carry and interpret optical information.In doing so,this could transform the computers of tomorrow,allowing them to effectively process infonna- tion at much faster speeds.”6. The researchers expect that the results of this research will be integrated into computers within ten years .In the short term,the glass is already being developed and used in next-generation computer memory technology known as CRAM,which may ultimately be integrated with the advances reported. The result of the research can help computers to increase_________.A: optical informationB: processing speedsC: electronsD:positive chargesE: data technologiesF: all-optical systems

考题 根据以下材料,回答题 People have smoked cigarettes for a longtime now. The tobacco which is used to make cigarettes was first grown in whatis now part of the United States. Christopher Columbus, who discovered America,saw the Indians smoking. Soon the dried leaves were transported to Europe. In thelate 1800s, the Turks made cigarettes popular. Cigarette smoke contains at least twoharmful substances, tar and nicotine. Tar, which forms as the tobacco burns,damages the lungs and therefore affects breathing. Nicotine, which is found inthe 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 theirstomachs. 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 andfeet. It plays an important role in increasing smokers′ risk of heart disease andstroke. Smoking cigarettes is dangerous. Cigarettesmoking was the cause of lung cancer and several other deadly diseases. What is the main purpose of the firstparagraph 查看材料A.To tell us the bad effects caused bysmoking cigarettes. B.To introduce the history of smoking. C.To let us know what the cigarettes aremade from. D.To tell the readers that Columbus foundthe Indians smoking.

考题 问答题Passage 2  (1) A one-month survey results indicate that smoking, alcohol and marijuana use increase among residents of Manhattan during the five to eight weeks after the terrorist attacks on the World Trade Center which took place on September 11, 2001. Almost one-third of the nearly 1000 persons interviewed reported an increased use of alcohol, marijuana, or cigarettes following the September 11 attacks. About one-fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about one tenth reported an increase in smoking, and 3.2% said they had increased their use of marijuana.  (2) The investigators found survey participants by randomly dialing New York City phone numbers and screened potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants were asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22.6% of the participants reported smoking cigarettes, 59.1% drinking alcohol, and 4.4% using marijuana. After September 11, 23.4% reported smoking cigarettes, 4.4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported imbibing at least one extra drink a day.  The researchers found that people who reported an increase in substance abuse were more likely to suffer from post-traumatic stress disorder (PTSD) and from depression (3) people who reported an increase in cigarette smoking or marijuana use were also more likely to have both PTSD and depression, while those people who reported an increase in alcohol use were more likely to have depression only. (4) Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from one’s home, losing possessions during the attacks, or being involved in the rescue efforts were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.  Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. (5) Demographic factors such as age, marital status, and income seemed tip play a more critical role in determining if the events of September 11 led to an increase in substance use.

考题 问答题Smoking bans in public places are becoming more and more common in China. Whether the right of the non-smoker to breathe in fresh air outweighs that of the smoker to smoke freely is a matter of opinion, manifesting itself in a heated smoking ban debate. The following are opinions from both sides on this issue. Read the excerpts carefully and write your response in about 300 words, in which you should:  1. summarize briefly the opinions from both sides, and then  2. give your comment.  Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks.  A smoking ban is a public policy that includes criminal laws and health regulations that prohibit smoking in certain public places and workspaces. There are many reasons why smoking bans originated, but most of these have medical origins. Research has shown secondhand smoke is almost as harmful as smoking in and of itself. The effects of secondhand smoke are relatively the same as smoking. Lung disease, heart disease, bronchitis and asthma are common. Those who live in homes with smokers have a 20-30 percent higher risk of developing lung cancer than those who do not live with a smoker.  Smoking bans are also imposed because they improve air quality in restaurants and other establishments. In Beijing, it is now illegal to smoke in all hospitality venues. Studies have also shown employees are exposed to far fewer toxins in areas where smoking is banned in the workplace.  Despite the positive effects on health and air quality, many people are still opposed to smoking bans in China. Critics oppose smoking bans and see these laws as an example of the government interfering in people’s lives. They look at the effects on smokers, not those on non-smokers who are subjected to second-hand smoke. Other critics emphasize the rights of the property owner and draw distinctions between public places, such as government building and privately owned businesses, such as stores and restaurants.  Some critics of smoking bans believe that outlawing smoking in the workplace may cause smokers to simply move their smoking elsewhere. Instead of smoking indoors, workers may begin smoking in public parks and exposing a new set of people to their secondhand smoke.
