1、MemoriesMost episodes of absent-mindedness forgetting where you left something or wondering why you just entered a room are caused by a simple lack of attention, says Schacter. "You are supposed to remember something, but you haven\'t encoded it deeply."Encoding, Schacter says, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don\'t pay attention to what you did because you are involved in a conversation, you will probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn\'t failing you," says Schacter. " Rather, you didn\'t give your memory system the information it needed. "Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox. " Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that.Visual cues can help prevent absent-mindedness, says Sclnacter." But be sure the cue is clear and available,"he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table don\'t leave it in the medicine chest and write yourself a note that you keep in a pocket.Another common episode of absent-mindedness: walking into a room and wondering why you are there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. ____.【单选题】

2、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。

3、Cancer1. Cancer 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(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 or order.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, or exposure to carcinogens (致症物) in the workplace or in the environment. Some gene alterations are inherited.3. 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, 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 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.Cancer patients may differ in their ______.【单选题】

A.side effects

B.prescription medicines

C.control or order

D.tolerance for pain

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 for pain，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。

4、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 ____ with their child, providing a bed or so far on the ward.But until the 1970s this practice was not only frowned upon, it was actively discouraged. Staff worried that the children were upset when their parents left, and so there was a blanket ban.A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse! I want my mummy" published in 1974 , changed the face of paediatric nursing.Martin Johnson, a professor of 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 visit a small child in hospital the child would be upset and inconsolable for hours. ""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 eve 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. ""Her research put an end to the days when parents handed their children over to strangers at the door of the hospital ward. ""As a result of her work, parents and careers are now recognized as partners and are afforded the opportunity to stay with their children whilst they are in hospital, which has dramatically improved both parents\' and children\'s experience of care. "【单选题】

A.soundly

B.overtime

C.fortnight

D.overnight

正确答案:D

答案解析:给父母在病房里提供床或沙发，是让他们和孩子一起过夜。overnight:整夜地，意思符合题意。

5、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 ____ 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 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 doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】
