1、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac 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 forthe treatment of heart diseases such as heart failure and heart attack, experts say. "We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professorof 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 orif they could be renewed," he said. The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover 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 that promote this process to stimulate regeneration after forexample, 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-authorDr. Ratan Bhardwaj. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said. With this finding, scientists are "opening the doorto potential therapies 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.It is not known yet if the rate of cell turnover in diseased hearts____. 【单选题】
A.s high enough to replace cells faster than they re dying off
B.is of any use to researchers
C.is the same as that in healthy hearts
D.changes over time
正确答案:C
答案解析:最后一句说:心脏产生的新细胞的数量是按照健康心脏计算的,而有心脏病的细胞更替率是否与健康心脏相同还不得而知。
2、CancerCancer is agroupof 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 ortumor. 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 ororder.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, orexposure to carcinogens (致癌物) in the workplace orin the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy (化疗), hormone therapy, and biological therapy. The doctormay use one method ora 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 forcancer 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 forpain. Most pain occurs when the cancer grows and presses against bones, organs, ornerves. Pain may also be a side effect of treatment. However, pain can generally be relieved orreduced with prescription medicines orover-the-counter drugs recommended by the doctor.Paragraph 2____.【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:E
答案解析:第二段主题句为第一句,其意思是:科学家研究证明,癌症是由正常情况下控制细胞生长和死亡的基因发生突变引起的。由此推断,该段回答了E选项“What causes cancer?”所提问题,故E为正确答案。
3、GypsiesWhen school was out, I hurried to find my sister and get out of the schoolyard before seeing anybody in my class. But Barbara and her friends had beaten us to the playground entrance and they seemed to be waiting forus. Barbara said, "So now you\'re in the A class. " She sounded impressed. "What\'s the A class?" I asked. Everybody made superioryet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, dopey? Didn\'t you know you were in the C class before, way in the back of the room?" Of course I hadn\'t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, and the idea of subdivisions within a grade had never occurred to me. The subdividing forthe first marking period had been done before I came to the school, and 1 had never, in the six weeks I\'d been there, talked to anyone long enough to find out about the A, B, and C classes.I still could not understand why that had made such a difference to Barbara and her friends. I didn\'t yet know that it was shameful and dirty to be a transient laborer and ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house.I didn\'t know that we were gypsies, really (how that thought would have excited me then!), and that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn\'t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here and there like mists orwinds. I didn\'t know that I was the only child who had camped on the Baumann\'s land ever to get out of the C class. I didn\'t know that school administrators and civic leaders held conferences to talk about the problem of transient laborers.I only knew that fortwo happy days I walked to school with Barbara and her friends, played hopscotch and jumped rope with them at class intervals, and was even invited into the house forsome ginger ale ----a strange drink I had never tasted before.Which of the following is not characteristic of Gypsies?【单选题】
A.Wandering around the world
B.Make ginger ale in their house.
C.Never plant something.
D.Had been foreigners wherever they go.
正确答案:C
答案解析:吉普赛人住帐篷,没什么房子,因而也不会在房子里做ginger ale。另外三项都是他们的生活特色。

5、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 emotional 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 ____ orto 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 orphysical 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 orstaying asleep; felt unhappy, sad, ordepressed; felt hopeless about the future; felt vexed, antsy ortense; 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 professorat 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.effects
B.methods
C.steps
D.directions
正确答案:A
答案解析:句中的or是“即”,也就是说,to have self-medicating加上填入的词之后的意思相当于to improve mood。四个选项中只有选项A的effects(效果)是填入空格的最合适的词。to improve mood是自我治疗的效果。其他三个选项methods、steps、directions与self-medicating连用,意思分别为“自我治疗的方法”、“自我治疗的步骤”、“自我治疗的指导”,与句子的意思不相配。
6、Breast Cancer Deaths Record LowThe number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year forthe first time since records began.The Cancer\' Research UK data showed that 11.990 women died in the UK in 2007.The previous lowest figure had been recorded in 1971-the year records began-after which it rose steadily year by year until the late 1980s.ProfessorPeter Johnson, Cancer Research UK\'s chief clinician. said: "It\'s incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often.""Research has played a crucial role in this progress leading to improved treatments and better management forwomen with the disease.""The introduction of the NHS (国民保健制度) breast screening 3 program has also contributed as women are more likely to survive the earlier cancer is diagnosed."Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease - a 50% rise in 25 years.The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 and 400 deaths each year until 2004.There was a slight rise in 2005 and then two years of falls.Dr. Sarah Cant, policy manager at Breakthrough Breast Cancer said: "It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments, breast screening and awareness of the disease. ""However, this is still too many women and incidence of the disease is increasing year by year. "The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity(肥胖) and alcohol consumption.Breast cancer is more common in the UK than in many other countries.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:本题难度较大,答案依据不明显,需要通读全文。通读全文可以发现,文文章没有提及英国乳腺癌发生情况和其他国家的对比,所以本题未提及,答案是C。
7、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. and the last “official” stocks of live virus bred mistrust of the US and Russia, forno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fortests on new treatments and vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US and Russia? ____. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】
A.Difficult
B.Hard
C.Safe
D.Simple
正确答案:D
答案解析:从紧随其后的句子来看,用simple是正确的。difficult,hard和safe都跟后面的句子在意思上不连贯。
8、The document was compiled by the Department of Health.【单选题】
A.written

9、Some students lose marks in their examinations simply because they don\'t read questions carefully.【单选题】
A.easily
B.quickly
C.just
D.frequently
正确答案:A
答案解析:simply和easily都可以表示“容易地、毫不费力地”;quickly:快速地;frequently:经常地、频繁地,强调频率高;just:仅仅、只不过。
10、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed orsofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be upsetwhen their parents left, and so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professorof nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care."Pamela\'s study was done against the background of a lively debate in paediatrics and psychology as to the degree women should spend with children in the outside world and the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to ____a small child in hospital the child would be upsetand inconsolable (无法安慰的) forhours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope that mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone and depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive and general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handed their children over to strangers at the doorof the hospital ward.""As a result of her work, parents are now recognized as partners in care and are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' and children\'s experience of care." 【单选题】
A.worry
B.control
C.visit
D.take
正确答案:C
答案解析:本题难度不大,考查词义辨析,干扰项干扰不大,可以先看选项得到信息提示。文章此处是说“……如果母亲到医院来探望孩子……”,答案是C。
