1、SemcoAt 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts for ships. Semler Junior worked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctor who treated him said, "There\'s nothing wrong with you. But if you continue like this, you\'ll find a new home in our hospital." Semler got the message. He changed the way he worked. In fact, he changed the way his employees worked too.He let his workers take more responsibility so that they would be the ones worrying when things went wrong. He allowed them to set their own salaries, and he cut all the jobs he thought were unnecessary, like receptionists and secretaries. This saved money and brought more equality to the company. "Everyone at Semco, even top managers, meets guests in reception, does the photocopying, sends faxes, types letters and dials the phone."He completely reorganized the office, instead of walls, they have plants at Semco, so bosses can\'t shut themselves away from everyone else. ____ As for uniforms, some people wear suits and others wear T - shirts.Semler says, "We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour. He doesn\'t even pretend to be busy. But when a Semco pump an the other side of the world fails and millions of gallons of oil are about to spill into the sea, Rubin springs into action.He knows everything there is to know about our pumps and how to fix them. That\'s when he earns his salary. No one cares if he doesn\'t look busy the rest of the time."Semco has flexible working hours, the employees decide when they need to arrive at work, The employees also evaluate their bosses twice a year. Also, Semco lets its workers use the company\'s machines for their own projects, and makes them take holidays for at least thirty days a year.It sounds perfect, but does it work? The answer is in the numbers. In the last six years, Semco\'s revenues have gone from $ 35 million to $ 212 million. The company has grown from eight hundred employees to 3,000, Why?Semler says it\'s because of "peer pressure". Peer pressure makes everyone work hard for everyone else. doing his job well, the other workers will not allow the situation to continue. In other words, Ricardo Semler treats his workers like adults and expects them to act like adults, And they do. 【单选题】

2、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.Paragraph 3 ______【单选题】

A.How is cancer treated?

B.Does cancer always cause pain?

C.Can cancer be prevented?

D.What is cancer?

3、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.The human heart stops producing cardiac cells ______.【单选题】

A.when a person becomes old

B.as soon as a person gets sick

C.immediately after a person is born

D.once a person dies

答案解析:本题有一定难度，需要吃透原文句意，答案依据是文章第一段，谈到科学家发现人一生中心脏都会不停地制造新的心肌细胞，尽管新细胞产生的速度随年龄增长而放慢，换句话说，只有人死了，心脏才会停止制造心肌细胞，回来看选项，D项和原文句意相符，是答案。

4、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 that 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 ____ 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】

A.young

B.old

C.single

D.experienced

正确答案:C

答案解析:本题难度不大，考查词义辨析，考查single的用法。前面提到了married(adults)，中间是连词and，很明显，此处是指single( adults)，即研究对象包括204名已婚和未婚的成年人，答案是C。

5、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - author Daniet J. Taylor said in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylor said.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) and a decline in college students\' academic performance.The study included 64 psychology, nursing and medical students, average age 27. 4 years, who were divided into two groups—low GPAs and high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."In the first study, students who stay up late ______.【单选题】

A.had lower GPAs

B.had higher GPAs

C.performed equally well in their studies
