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.The finding could prove to be useful to ______.【单选题】

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 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 ____ 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】

B.some
C.much
D.any
正确答案:C
答案解析:本题有一定难度,修饰比较级greater只能用副词much,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.Paragraph 2 ______【单选题】
A.How is cancer treated?
B.Does cancer always cause pain?
C.Can cancer be prevented?
D.What is cancer?
E.How common is cancer?
F.What causes cancer?
正确答案:F
答案解析:本题难度也不大,段落主旨句比较明显,是文章第二段的第一句,谈到科学家已查明癌症是由基因变化引起的,基因通常控制着细胞的生长和死亡,回来看选项,F项What causes cancer?简单概括了本段意思,是答案。
5、Acceptance of Chronic IllnessForchronically ill patients, giving up the hope that they will get better may actually lead to more happiness, U. S. researchers suggest."Hope is an important part of happiness, but there\'s a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness," Dr. Peter A. Ubel from the University of Michigan Health System said in a university news release.He and his colleagues studied patients who\'d just had a colostomy (结肠造口术), which means their colons (结肠) were removed and they had to have bowel (肠) movements in a pouch (小袋) outside the body. At the time of the surgery, some patients were told the procedure was reversible and they\'d have a second operation in a few months to reconnect their bowels. Other patients were told the colostomy was permanent.The patients were followed forsix months, and the researchers found that those without hope of regaining normal bowel function were happier than those with reversible colostomies."We think they were happier because they got on with their life. They realized the cards they were dealt, and recognized that they had no choice but to play with those cards," Ubel said. "The othergroupwas waiting fortheir colostomy to be reversed. They contrasted their current life with the life they hoped to lead, and didn\'t make the best of their current situation. "The study, published in the November edition of Health Psychology, also may explain why people whose spouse dies often recover better emotionally over time than those who get divorced, the researchers said.That\'s because people whose husband orwife dies have closure (结束), while those who get divorced may still have hope forsome chance of making up, they explained.Chronically ill patients may be happier ______.【单选题】
A.if they keep thinking of their past
B.if they believe they\'ll recover
C.if they put off moving on
D.if they manage to get on with their life
