    Most Adults in US Have Low Risk of Heart Disease
    More than 80 percent of US adults have a less than 10-percent risk of developing heart disease in the next 10 years,according to a report in the Journal of the American College of Cardiology.Just 3 percent have a risk that exceeds 20 percent.
    "I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary heart disease is distributed in the US population,"lead author Dr.Earl S.Ford,from the Centers for Disease Control and Prevention in Atlanta,said in a statement.
    The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age,who narticipated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.
    Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent,and 3 percent had a risk above 20 percent.
    The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast,race or ethnicity had little effect on risk distributions.
    Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have ahigh or immediate risk,Dr.Daniel S.Berman,from Cedars-Sinai Medical Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine,note in a related editorial.
    Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add.

    The main purpose of the passage is to______.
    A:introduce that most adults in US adults have low risk of heart disease
    B:give treatment measures to reduce the risk of developing heart disease for US adults
    C:describe the research made by the Centers for Disease Control and Prevention
    D:warn people that they should pay attention to the threat of heart disease immediately

    答案:A
    解析:
    由文章第四段可知,15%的美国成年人有10%到20%的患心脏病风险几率。
    由文章第五段可知,受试者中最具心脏病风险的群体比例会随着年龄的增加而增加,而人种和种族对此几乎无影响。国别在此并未提及。
    由文章第三段可知,这些发现是基于从13 769位受试者中得到的数据进行分析的结果,故选B。
    文章最后一段中提到,需要有积极的治疗方法和公共卫生策略来降低人口总体的患心脏病风险。

    Most Adults in U.S.Have Low Risk of Heart Disease
    More than 80 percent of U .S.adults have a less than 10-percent risk of developing heart dis- ease in the next 10 years,according to a report in the Journal of the American College of Cardiolo-gy(心脏病学).Just 3 percent have a risk that exceeds 20 percent.
    “I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary(心脏冠状动脉的)heart disease is distributed in the U. S. population ,” lead(带头的)author Dr. Earl S. Ford , from the Centers for Disease Control and Prevention in Atlanta,said in a statement.
    The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age , who participated in the Third National Health and Nutrition(营养的供给)Examination Sur- vey from 1988 to 1994.
    Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent and 3 percent had a risk above 20 percent,
    The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group. By contrast, race or ethnicity(种族划分)had little effect on risk distributions.
    Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have a high or immediate risk,Dr. Daniel S .Berman,from Cedars-Sinai Medi- cal Center in Los Angeles,and Dr. Nathan D.Wong,from the University of California at Irvine, note in a related editorial.
    Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add.

    Which of the following statements is NOT right?
    A:The 10-year risk of heart disease is low for most U.S.adult.
    B: Elderly people have a higher risk of heart disease than younger people.
    C: Women have a higher risk of heart disease than man.
    D: The distribution of the risk of heart disease are hardly related to race.

    答案:C
    解析:
    文章首段提到就提到美国80%以上的成年人未来十年内患心脏病的风险低于 10%,故A项正确;由第五段最后一句话“By contrast , race or ethnicity(种族划分)had little effect on risk distributions.”可知种族对患病风险的分布影响很小,故D项正确;由第五段“The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.”可知实验对象年龄越大,在高风险组中所占的比例也越大,男人进入该组的可能性也大于女性,故B项正确,C项错误。
    由第四段“Overall , 82 percent of adults had a risk of less than 10 percent , 15 percent had a risk that fell between 10 to 20 percent and 3 percent had a risk above 20 percent.”可知,美国80%以上的成年人未来十年内患心脏病的风险低于10% ,15%的成年人未来患心脏病的风险介于10%~20% ,3%的成年人患心脏病的风险在20%以上。故选A。
    题干问的是下列哪个选项对患病风险的分布影响最小。由文中第五段可知,心脏病的患病风险的分布与年龄和性别有很大的关系,种族对患病风险事物分布影响很小,D项“血型”在文中没有提及,故排除。故选C。
    由文中原句“15 percent had a risk that fell between 10 to 20 percent”可知,15%的成年人未来十年内患心脏病的风险介于10%~20%,故选C。注意文中的几个百分数不要弄混淆了
    两位科学家讲到,尽管大多数成年人10年内患心脏病的风险较低,但在有风险者中,很大一部分所面临的风险却是很高或者刻不容缓的,故只有采取积极的治疗措施和公共卫生政策(Aggressive treatment measures and public health strategies are needed)才能降低所有人群患病的风险概率。

    Napping to a Healthier Heart?
    1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.
    2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.
    3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.
    4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.
    5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.
    6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.

    So far there have not been definite data to confirm______.
    A:where fewer people die from heart problem
    B:whether they have the risk of heart attack,heart failure or stroke
    C:would probably have lower rates of heart disease
    D:how to test a person's NT-proBNP level in the blood by himself
    E:his heart muscle would be under pressure in some way
    F:that napping is of great benefit to women too

    答案:F
    解析:
    第二段主要介绍了加利福尼亚大学一个团队所进行的研究。通过检查心脏病人的NT-proBNP水平,发现水平最高的病人与水平最低的病人之间患心脏病的可能性相差近8倍。
    第三段说到,研究涉及的多是男性,并发现年老且患有糖尿病或高血压者NT-proBNP的水平最高。
    由第四段的内容可知,其他研究者认为还要确认一些问题,如心脏病病人的蛋白质水平是否影响其治疗;他们还想知道更多的积极治疗能否减少病人得心脏病或中风的机会。
    第五段说到,地中海国家的成年人普遍都午睡,而且患心脏病的几率较低。哈佛大学和雅典大学的研究证明,每周午睡三次,每次30分钟的人比完全不午睡的人死于心脏病的几率低37%。
    由第一段最后两句可知,研究人员检测血液中蛋白质的水平,他们称血液中这种蛋白质水平高的人得心脏病或中风的几率高,故选B。
    由第三段第一句可知,血液中含有高浓度的该种蛋白质证明心肌受到了压迫。
    由文章第五段的内容可知,定期午睡的人患心脏病的几率更低。
    由第三段第二句和文章的最后一句可知,研究对象多为男性,并且由于在调查期间女性研究对象死亡的并不多,所以无法判断午睡对女性的影响。

    Need for Emphasis on Treatment

    AIDS programs in developing countries put too little emphasis on treatment,the World Health Organization
    said Tuesday,asking for more small community-based clinics to be opened to treat HIV-infected people.
    An estimated 36 million to 46 million people are living with AIDS,two-thirds of them in Africa,but
    only 440,000 people in developing countries were receiving treatment by the end of 2003,the UN health
    agency said in its annual report.
    "Without treatment,all of them will die a premature and in most cases painful death,"the WHO said in
    the 169-page World Health Report.
    WHO Director General Lee Jong-wook said community-based treatment should be added to disease pre-
    vention and care for sufferers in AIDS programs.
    "Future generations will judge our time in large part by our response to the AIDS disease,"Lee said.
    "By tackling it decisively we will also be building health systems that can meet the health needs of
    today and tomorrow. This is a historic opportunity we cannot afford to miss,"he added.
    Antiretroviral drugs enable people hit by AIDS to live longer. The annual cost of treatment,which was
    about $10,000 when the drugs were first developed,has dropped to about$150.
    Treatment programs also help AIDS prevention efforts,the report said,citing great demands for testing
    and counseling where treatment has been made available.
    Good counseling in turn leads to more effective prevention in those who are uninfected,and significantly
    reduces the potential for HIV carriers to pass on the infection,the report said.
    Since its discovery in the 1980s,more than 20 million have died of AIDS,mostly in poor countries.

    According to Lee,our response to the AIDS disease is__________.
    A:a matter of great significance
    B:a matter of little significance
    C:overemphasized
    D:timely

    答案:A
    解析:
    本题为事实细节分析题。从文章第二段“An estimated 36 million to 46 million people are with AIDS,two-thirds of them in Africa,but only 440,000 people in developing countries were re-ceiving treatment by the end of 2003”可知,在非洲艾滋病患者高达两、三千万人,而生活在发展 中国家的艾滋病患者,接受治疗的人数却只有44万,相对来说太少了。
    从文章第二段中最后一句话中“annual report",可知世界卫生组织的“世界卫生报告” 是每年发表一次。
    本题为推理判断题。从文章第四段和第五段内容可知,Lee说到:社会应对艾滋病的预 防加大力度,多关心艾滋病患者;后代对我们这一时代的评价主要取决于我们对待艾滋病的反 应。由此可见:对待艾滋病,我们的反应是至关重要的一件事。故选A。
    文章倒数第三段提到,对于艾滋病的治疗对预防艾滋病也颇有益处。
    文章最后一段指出,自从20世纪80年代发现艾滋病到现在,已有两千万人死于该病。 第三篇 本篇文章主要讲述了几种解决讲话时口干问题的方法,提出在演讲之前不能饮酒。告诫大 家改掉坏毛病保护好嗓子。

    答案:
    解析:
    Will E-books Replace Traditional Books? There is no denyingthe fact that e-books have gained increasing popularity in the past years alongwith the development of information technology. Actually, modem readers seem tospend more time on e-books than on traditional ones.
    As a consequence, ithas emerged as a hotly debated topic whether e-books will take the place oftraditional books in the future. Some hold the positive view. They claim thatit is natural for books to become electronic as mankind steps into a digitalage. Compared with traditional books, e-books have some obvious advantages. Forone thing, it is convenient to read online as modem people have easy access tothe Interact. For another, reading e-books saves money.
    Personally, Ibelieve that e-books cannot replace all traditional books. Firstly, you canmark a traditional book and write your comments in the margin but you can hardlydo that on e-books. Secondly, for many people, only the smell of print and thefeel of paper can provide, the true sense of reading and learning. Therefore,in my opinion, traditional books will still exist in the future.

    Better Control of TB Seen If a Faster Cure Is Found
    The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis(结核病).Most times , the infection remains inactive(不活跃
    的).But each year about eight million people develop active cases of TB,usually in their lungs. Two million people die of it.The disease has increased with the spread of AIDS and drug-resist-ant forms of tuberculosis.
    Current treatments take at least six months.Patients have to take a combination of several antibiotic(抗生素)drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection(传染病)that resists treatment. Public health experts agree that a faster-act-ing cure for tuberculosis would be more effective.Now a study estimates just how effective it might be .A professor of international health at Harvard University led the study.Joshua Salomon says a shorter treatment program would likely mean not just more patients cured.It would also mean fe- wer infectious patients who can pass on their infection to others.
    The researchers developed a mathematical(数学的)model to examine the effects of a two-month treatment plan.They tested the model with current TB conditions in Southeast Asia.The scientists found that a two-month treatment could prevent about twenty percent of new cases.And it might prevent about twenty-five percent of TB deaths.The model shows that these reductions would take place between two thousand twelve and two thousand thirty.That is,if a faster cure is developed and in wide use by two thousand twelve.
    The World Health Organization developed the DOTS program in nineteen ninety.DOTS(短期直接观察治疗)is Directly Observed Treatment, Short-course. Health workers watch tubercu- losis patients take their daily pills to make sure they continue treatment.
    Earlier this year,an international partnership of organizations announced a plan to expand the DOTS program.The ten-year plan also aims to finance research into new TB drugs.The four most common drugs used now are more than forty years old.The Global Alliance for TB Drug De- velopment(全球结核病药物开发联盟)says its long-term goal is a treatment that could work in as few as ten doses.

    Now there are_______most common drugs being used for more than forty years.
    A: one
    B: two
    C: three
    D:.four

    答案:D
    解析:
    根据文章首段“The World Health Organization estimates that about one-third of all peo-ple are infected with bacteria that cause tuberculosis(结核病)…each year about eight mu- lion people develop active cases of TB… Two million people die of it.”可知,大约有三分之一的人会感染上结核病细菌,每年约有800万人在肺部转变为活性细菌,大约有二百万人死于结核病。故选C。
    由第三段的最后两句“The model shows that these reductions would take place between 2020 and 2030. That is, if a faster cure is developed and in wide use by 2020”可知,一种又快又广的治疗方法大约在2020年至2030年,最快也得在2020年。故选B。
    由最后一段“The four most common drugs used now are more than forty years old”可知,现在最常用的四种治疗结核病的药已有四十多年的历史了。所以要加大投资金额用于研发新药品。
    根据题干,我们可以直接定位到第二段。由首句“Current treatments take at least six months”可知目前的治疗肺结核的疗程至少是六个月,故A项正确;根据Joshua Salomon 所说的话可知疗程较短的计划可能意味着更多病人被治好,也意味着将感染传递给别人的病人也会更少,故B、C两项正确。由“But many people stop as soon as they feel bet-ter. Doing that can lead to an infection(传染病)that resists treatment.”可知,结核病患者不能感觉好一点就停止吃药,这样容易发展成抗药性的传染性肺结核。故选D。
    由文章最后一句话“The Global Alliance for TB Drug Development(全球结核病药物开发联盟)says its long-term goal is a treatment that could work in as few as ten doses.”可知全球结核病药物开发联盟的目标是研制出一种最好是喝10剂就能治愈结核的药物。 dose剂量,药量;一服(药),一剂(药)。故选C。

    Napping to a Healthier Heart?
    1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.
    2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.
    3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.
    4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.
    5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.
    6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.

    If a person has a high level of NT-proBNP______.
    A:where fewer people die from heart problem
    B:whether they have the risk of heart attack,heart failure or stroke
    C:would probably have lower rates of heart disease
    D:how to test a person's NT-proBNP level in the blood by himself
    E:his heart muscle would be under pressure in some way
    F:that napping is of great benefit to women too

    答案:E
    解析:
    第二段主要介绍了加利福尼亚大学一个团队所进行的研究。通过检查心脏病人的NT-proBNP水平,发现水平最高的病人与水平最低的病人之间患心脏病的可能性相差近8倍。
    第三段说到,研究涉及的多是男性,并发现年老且患有糖尿病或高血压者NT-proBNP的水平最高。
    由第四段的内容可知,其他研究者认为还要确认一些问题,如心脏病病人的蛋白质水平是否影响其治疗;他们还想知道更多的积极治疗能否减少病人得心脏病或中风的机会。
    第五段说到,地中海国家的成年人普遍都午睡,而且患心脏病的几率较低。哈佛大学和雅典大学的研究证明,每周午睡三次,每次30分钟的人比完全不午睡的人死于心脏病的几率低37%。
    由第一段最后两句可知,研究人员检测血液中蛋白质的水平,他们称血液中这种蛋白质水平高的人得心脏病或中风的几率高,故选B。
    由第三段第一句可知,血液中含有高浓度的该种蛋白质证明心肌受到了压迫。
    由文章第五段的内容可知,定期午睡的人患心脏病的几率更低。
    由第三段第二句和文章的最后一句可知,研究对象多为男性,并且由于在调查期间女性研究对象死亡的并不多,所以无法判断午睡对女性的影响。

    Need for Emphasis on Treatment

    AIDS programs in developing countries put too little emphasis on treatment,the World Health Organization
    said Tuesday,asking for more small community-based clinics to be opened to treat HIV-infected people.
    An estimated 36 million to 46 million people are living with AIDS,two-thirds of them in Africa,but
    only 440,000 people in developing countries were receiving treatment by the end of 2003,the UN health
    agency said in its annual report.
    "Without treatment,all of them will die a premature and in most cases painful death,"the WHO said in
    the 169-page World Health Report.
    WHO Director General Lee Jong-wook said community-based treatment should be added to disease pre-
    vention and care for sufferers in AIDS programs.
    "Future generations will judge our time in large part by our response to the AIDS disease,"Lee said.
    "By tackling it decisively we will also be building health systems that can meet the health needs of
    today and tomorrow. This is a historic opportunity we cannot afford to miss,"he added.
    Antiretroviral drugs enable people hit by AIDS to live longer. The annual cost of treatment,which was
    about $10,000 when the drugs were first developed,has dropped to about$150.
    Treatment programs also help AIDS prevention efforts,the report said,citing great demands for testing
    and counseling where treatment has been made available.
    Good counseling in turn leads to more effective prevention in those who are uninfected,and significantly
    reduces the potential for HIV carriers to pass on the infection,the report said.
    Since its discovery in the 1980s,more than 20 million have died of AIDS,mostly in poor countries.

    AIDS treatment programs may also result in___________.
    A:better drugs
    B:lower yearly cost
    C:more effective prevention
    D:greater emphasis on treatment

    答案:C
    解析:
    本题为事实细节分析题。从文章第二段“An estimated 36 million to 46 million people are with AIDS,two-thirds of them in Africa,but only 440,000 people in developing countries were re-ceiving treatment by the end of 2003”可知,在非洲艾滋病患者高达两、三千万人,而生活在发展 中国家的艾滋病患者,接受治疗的人数却只有44万,相对来说太少了。
    从文章第二段中最后一句话中“annual report",可知世界卫生组织的“世界卫生报告” 是每年发表一次。
    本题为推理判断题。从文章第四段和第五段内容可知,Lee说到:社会应对艾滋病的预 防加大力度,多关心艾滋病患者;后代对我们这一时代的评价主要取决于我们对待艾滋病的反 应。由此可见:对待艾滋病,我们的反应是至关重要的一件事。故选A。
    文章倒数第三段提到,对于艾滋病的治疗对预防艾滋病也颇有益处。
    文章最后一段指出,自从20世纪80年代发现艾滋病到现在,已有两千万人死于该病。 第三篇 本篇文章主要讲述了几种解决讲话时口干问题的方法,提出在演讲之前不能饮酒。告诫大 家改掉坏毛病保护好嗓子。
