1、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived ____ benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools located in high, moderate and low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression and smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】

A.social

B.financial

C.emotional

D.political

正确答案:C

答案解析:抽烟缓解抑郁是一种情绪上(emotional)的得益，不会是social（社会上的）、financial（经济上的）或political（政治上的）得益。所以答案是C。

2、CancerCancer is a group of many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor. Benign (良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order.Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet radiation from the sun, or exposure to carcinogens (致癌物) in the workplace or in the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient\'s age and general health, and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Patients and doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells and the risks of possible side effects.Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, and the patient\'s tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor.Paragraph 3____.【单选题】

A.Does cancer always cause pain

B.Can cancer be prevented

C.What is cancer

D.How common is cancer

E.What causes cancer

F.How is cancer treated

正确答案:F

答案解析:第三段没有主题句，但浏览该段会发现其中的高频词treatment，由此推断，该段讲述了癌症的治疗方法。段中详细介绍了癌症的治疗方法，如手术切除、放射治疗、化疗、生物学治疗等，但这些治疗方法会产生副作用。由此推断，该段回答了F选项“How is cancer treated?”所提出的问题，故F为正确答案。

3、Human Heart Can Make New CellsSolving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac(心脏的 ) cells throughout the life span, although the rate of new cell production slows with age.The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say."We find that the beating cells in the heart, cardiomyocytes (心肌细胞), are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.The process of renewing these cells changes over time, Frisen added. In a 20 - year - old, about I percent of cardiomyocytes are exchanged each year, but the turnover (更替) rate decreases with age to only 0.45 percent by age 75."If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals (药物) that promote this process to stimulate regeneration after, for example, a heart attack," Frisen said.That could lead to treatment that helps restore damaged hearts."A lot of people suffer from chronic heart failure," noted co - author Dr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.With this finding, scientists are "opening the door to potential therapies (疗法) to having ourselves heal ourselves." Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.In people in their mid -70s, only 0. 45 percent of cardiomyocytes ______.【单选题】

A.are still functional

B.are reduced each year

C.are replaced each year

D.are damaged each year

正确答案:C

答案解析:本题难度不大，答案依据比较明显。带着题干信息词回文章定位，答案依据是文章第四段第二句，谈到到了75岁，心肌细胞的更新率就降到每年0. 45%，换句话说，到75岁时．每年只有0. 45%的心肌细胞被更新，回来看选项，C项和原文句意相符，是答案。

4、They say Ireland\'s the BestIreland is the best place in the world to live in for 2005, according to a life quality ranking that appeared in Britain\'s Economist magazine last week.The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being.The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life".Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality, and the high cost of living, Ireland scored an impressive 8.33 points out of 10.That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity and hunger, is rated the gloomiest (最差的) , picking up only 3.89 points."Although rising incomes and increased individual choices are highly valued, " the report said, "some of the factors associated with modernization such as the breakdown in traditional institutions and family values in part take away from a positive impact."Ireland wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life. "The magazine admitted measuring quality of life is not a straightforward thing to do, and that its findings would have their critics.No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark and Spain.The UK is positioned at No. 29, a much lower position chiefly because of the social and family breakdown recorded in official statistics. The US, which has the second highest per capita GDP after Luxembourg, took the 13th place in the survey. China was in the lower half the league at 60th.For 2,005 years, Ireland has been the best place for humans to live in.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:句子中的时间状语结构恰恰就是我们所说的一种可作为线索的特征结构（因为数字容易在文章中被查找到），我们利用2，005作为答案线索，在文章中找到答案相关句中提到的是“for 2005（对2005年而言）”，不是问题句中说的“for 2，005 years（在2005年的时间里）”，而且画线结构说“爱尔兰2005年被选为世界上最适合居住的地方”，显然这个内容与问题句的内容不一致，判断问题句的说法错误。

5、15 Million Americans Suffer from Social Anxiety DisorderSocial anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives, a new survey finds.The disorder leaves many isolated, ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help, the Anxiety Disorders Association of America reports."Social anxiety disorder is when somebody has an intense, persistent and irrational fear of social or performance situations," Jerilyn Ross, the association\'s president and CEO, said during a teleconference Wednesday."The condition causes people to avoid common, everyday situations and even other people for fear of being judged or criticized or humiliated or embarrassing themselves," Ross said.Social anxiety disorder can interfere with daily routines and job performance, Ross noted. "It also makes it very difficult for people to develop friends and romantic partnerships," she said.People with this disorder recognize their fear is excessive and irrational, Ross noted. "But they feel powerless to do anything about it," she said.Social anxiety disorder can start in the early teens, Dr. Mark H. Pollack, director of the Center for Anxiety and Traumatic Stress Disorders and a professor of psychiatry at Harvard Medical School, said during the teleconference."This is a disorder that starts affecting people early on," Pollack said. "The typical age of onset is early adolescence, age 12 or 13, and many individuals report a history of anxiety dating back to earlier childhood."The disorder also has physical symptoms, including heart palpitations, feelings that their throat will close up, sweating, blushing, faintness, trembling and stammering, Ross said.Among people with the disorder, 75 percent said the condition affected their ability to do normal activities. In addition, 69 percent said they didn\'t want people to think they were crazy, and 58 percent said they were embarrassed by their condition, Ross said.However, when the condition is diagnosed and treated, many reported improvement in their lives. In fact, 59 percent who were receiving treatment said treatment had a positive effect on their ability to have a romantic relationship. In addition, 39 percent who had received treatment said knowing that treatment can be successful aided their decision to get help, Ross noted.What do people with social anxiety disorder think of their fear?【单选题】

A.They think it\'s beyond their control.

B.They think it\'s beneficial.

C.They think it\'s controllable.

D.They think it\'s justified.

正确答案:A

答案解析:短文的第六段说，患有social anxiety disorder的人意识到他们的恐惧是过分的和非理性的，然而却对此无能为力。

6、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - author Daniet J. Taylor said in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylor said.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) and a decline in college students\' academic performance.The study included 64 psychology, nursing and medical students, average age 27. 4 years, who were divided into two groups—low GPAs and high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."In the first study, students who stay up late ______.【单选题】

A.had lower GPAs

B.had higher GPAs

C.performed equally well in their studies

D.had little difficulty concentrating during the day

正确答案:A

答案解析:本题有一定难度，需要吃透原文句意，答案依据在文章第二段后半部分，谈到早起的学生平均成绩高于晚睡的学生，换句话说，晚睡的学生成绩低，答案是A。

7、Waste Not, Want Not1 Bob and Clara Darlington, who own and run a farm in the North of England, have always looked for new ways of making money out of the produce they grow. Their SUCCESS began when they established a shop on their farm, so that people could come and buy fresh vegetables directly from them.2 The business was an immediate SUCCESS, and soon scored top marks in a competition set up by the Farm Retail Association to find the best farm shop in the country. The Association\'s inspectors found the Darling tons\' shop offered excellent service and value for money as well as quality fruit and vegetable.3 Clara Darlington is a trained chef and, in addition to a range of home-grown foods and other local produce, she began offering a variety of prepared meals which she had made herself in the farmhouse kitchen. A small cafe alongside the farm shop was soon added, with everything that visitors could taste on the menu also being for sale in the shop.4 Clara admits that starting the business was expensive, and she has worked very hard, but maintains that if the product is good, the public recognize this and buy it. "I aim to offer the highest quality to our customers, whether they come in for a loaf of bread, or take a whole dinner-party menu. I take it as a compliment if people take home one of my dishes to serve to their family and friends and get away with pretending they made it themselves. "5 So it was that the couple realized that they had a surplus of misshapen or damaged vegetables grown on the farm which were unsuitable for selling in the shop. Clara, not wishing to see them get thrown away, decided to turn them into soup.6 The soup met with the immediate approval of customers to the shop and Clara now produce different varieties. She spent much of the summer traveling up and down to London by rail, doing presentations of the soups. As a result, they are now served in first-class railway restaurant cars belonging to three companies as well as being stocked by a number of high-class London stores.Instead of throwing the damaged vegetables away, the couple ____.【单选题】

A.sell fresh vegetables

B.sell as much as possible

C.offer a variety of prepared meals

9、The Ideal HusbandScience now might be able to explain women\'s fascination with Brad Pitt\'s face and George Clooney\'s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.In the study by Daniel Kruger at the US\'s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a ____ romance, not for something longer.The study was published in the December issue of the US journal Personal Relationships.Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible for the development of masculine facial features and other sexual characteristics. It has been found to affect the body\'s ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.However, increased testosterone has also been linked to cheating and violence in relationships. So, these men might produce high quality offspring, but they don\'t always make great parents or faithful mates, Kruger says.The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.【单选题】

A.fast

B.brief

C.quick

D.swift

正确答案:B

答案解析:fast:快；brief:短暂；quick:快；swift: 快。这里有三个表示“快”的英文词，肯定不是合适的选项。另外紧随其后的短语是重复，其中有longer（更长一点）这个词，这就提醒我们应该用brief这个词。

10、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.The study included 204 married and 99 single adults who wore portable blood - pressure monitors for 24 hours. The monitors recorded blood pressure at random intervals and provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally do in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 ____ of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】
