1、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 forthe 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 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 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, 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, 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 (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.It is not known yet if the rate of cell turnover in diseased hearts ______.【单选题】
A.is 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: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,答案依据是文章最后一段最后一句,谈到心脏新细胞的制造数量是按照健康心脏来计算的,但是患病心脏的细胞更新率是否一样还是未知,回来看选项,C项和原文句意相符,是答案。
2、What are my chances of promotion if I stay here?【单选题】
A.retirement
B.advertisement
C.advancement
D.replacement
正确答案:C
答案解析:如果我还待在这干,我有升职的机会吗?promotion指“提升,晋级”,和advancement的引申意义“晋升”是同义词,A项指“退休”,B项指“广告”,D项指“代替”,三项的干扰性不强。本题考查的是advancement的引申意义。
3、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people orsingles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit forsingles orunhappily 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 authorJulianne 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 for24 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 ortwo readings in a clinic is not really ____ 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 issue 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 doctorvisits. People in happy marriages also have a source of emotional support, she said. 【单选题】
A.supportive
B.active
C.representative
D.protective
正确答案:C
答案解析:本题有一定难度,考查词义辨析。文章此处是说“在医诊室里得到一两个读数并不真正代表一天里的波动”,此处要用“代表”的意思,答案是C。
4、Cancer1. Cancer 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肿瘤). 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.2. 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(紫外线的) radiation from the sun, orexposure to carcinogens (致症物) in the workplace orin the environment. Some gene alterations are inherited.3. 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, weighting the likely benefits of killing cancer cells and the risks of possible side effects.4. 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.Cancer patients may differ in their ______.【单选题】
A.side effects
B.prescription medicines
C.control ororder
D.tolerance forpain
E.various factors
F.different genes
正确答案:D
答案解析:本题有一定难度,需要认真寻找答案依据。答案依据在文章第第四段第二句话:Whether a patient has pain may depend on … and the patients\' tolerance forpain,谈到病人是否感觉疼痛取决于癌症的类型,患病严重程度以及病人对疼痛的忍耐力,回来看选项,D项符合原文句意,是答案。
5、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 can come back 10 years after you were first diagnosed. 【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,文章没有提及在第一次被诊断出乳腺癌后,患者有可能10年后复发的情况,因此本题未提及,答案是C。
