2 . A new study has found that social media could be affecting the sleep of young adults. The study is a project of researchers at the University of Pittsburgh’s School of Medicine.They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep problems.“This is one of the first piece of evidence that social media use really can affect your sleep,” said Jessica C. Levenson, the lead author of a report on the study. The researchers set out to examine the connection between social media and sleep among young adults.The researchers wanted to find out how often young people used social media sites like Facebook. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also visited various social media accounts 30 times per week.Thirty percent of the study’s participants(参与者)reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were twice as likely to suffer from sleep problems.Researchers say social media can influence sleep in a number of ways. People can lose sleep by staying up too late looking at social media. Sensitive issues argued about on social media can cause excitement. Using an electronic device can disturb a body’s natural sleep rhythms because of the light coming from screens. The researchers note that in some cases, young adults who have a hard time sleeping may use social media to help them fall asleep, which may in turn lead to more problems sleeping because social media involve screen time that is interesting and can keep you awake.【小题1】What do the researchers suggest on a doctor’s treating young adults’ sleep problems?A．Knowing their living environment.B．Asking about the time they spent on social mediaC．Asking what social media sites they use.D．Inquiring about their sleeping habits.【小题2】What can we know about the study?A．Less than one-third of the participants in the study have problem sleeping.B．Doctors don’t think there is any way to cure sleeping problems caused by social media use.C．Social media use has something to do with young adults’ sleeping problems.D．Participants who like using Facebook are less likely to suffer from sleeping problems.【小题3】Social media use affects one’s sleep in the following ways except that ________.A．one will stay up lateB．one can get excited.C．one’s sleep rhythms will be disturbedD．one can fall fast asleep【小题4】What is the main idea of the passage?A．Social media have affected young adults’ sleep.B．How to deal with sleep problems.C．Social media takes up so much time.D．Sleep problems mainly result from social media.【小题5】The main purpose of the passage is to ________.A．informB．encourageC．persuadeD．advise

7 . Elizabeth Blackwell was born in England in 1821, and moved to New York City when she was ten years old. One day she decided that she wanted to become a doctor. That was nearly impossible for a woman in the middle of the nineteenth century. After writing many letters asking for admission to medical schools, she was finally accepted by a doctor in Philadelphia. She was so determined that she taught school and gave music lessons to get money for the cost of schooling.In 1849, after graduation from medical school, she decided to further her education in Paris. She wanted to be a surgeon, but a serious eye problem forced her to give up the idea.Upon returning to the United States, she found it difficult to start her own practice because she was a woman. By 1857 Elizabeth and her sister, also a doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides being the first woman physician and founding her own hospital , she also set up the first medical school for women.【小题1】What main obstacle almost destroyed Elizabeth’s chances for becoming for a doctor?A．She couldn’t set up her hospital.B．She wrote too many letters.C．She couldn’t graduate from medical school.D．She was a woman.【小题2】Why couldn’t Elizabeth Blackwell realize her dream of becoming a surgeon?A．She couldn’t get admitted to medical school.B．A serious eye problem stopped her.C．She decided to further her education in Paris.D．It was difficult for her to start a practice in the United States.【小题3】How many years passed between her graduation from medical school and the opening of her hospital?A．Nineteen yearsB．Ten yearsC．Eight yearsD．Thirty-six years【小题4】Eilzabeth Blackwell spent most of her life in ________.A．the United StatesB．ParisC．EnglandD．New York City【小题5】According to the passage, all of the following are “firsts” in the life of Elizabeth Blacekwell except that she ________.A．became the first woman physicianB．set up the first medical school for womenC．and several other women founded the first hospital for women and childrenD．was the first woman doctor

BThe phrase almost completes itself: midlife crisis. It's the stage in the middle of the journey when people feel youth vanishing, their prospects narrowing and death approaching.There's only one problem with the cliche (套话). It isn't true."In fact, there is almost no hard evidence for midlife crisis other than a few small pilot studies conducted decades ago," Barbara Hagerty writes in her new book, Life Reimagined. The bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift "can be exciting, rather than terrifying."Barbara Hagerty looks at some of the features of people who turn midlife into a rebirth. They break routines, because "autopilot is death." They choose purpose over happiness-having a clear sense of purpose even reduces the risk of Alzheimer's disease, They give priority to relationships, as careers often recede(逐渐淡化).Life Reimagined paints a picture of middle age that is far from gloomy, Midlife seems like the second big phase of decision-making. Your identity has been formed; you've built up your resources; and now you have the chance to take the big risks precisely because your foundation is already secure,Karl Barth described midlife precisely this way. At middle age, he wrote, "the sowing is behind; now is the time to reap. The run has been taken; now is the time to leap. Preparation has been made; now is the time for the venture of the work itself."The middle-aged person. Barth continued, can see death in the distance, but moves with a "measured haste" to get big new things done while there is still time.What Barth wrote decades ago is even truer today. People are healthy and energetic longer. We have presidential candidates running for their first term in office at age 68, 69 and 74．A longer lifespan is changing the narrative structure of life itself. What could have been considered the beginning of a descent is now a potential turning point-the turning point you are most equipped to take full advantage of.What does the author think of the phrase "midlife crisis"?A.It has led to a lot of debate.B.It is widely acknowledged.C.It is no longer fashionable.D.It misrepresents real life.How does Barbara Hagerty view midlife?A.It may be the beginning of a crisis.B.It can be a new phase of one's life.C.It can be terrifying for the unprepared.D.It may see old-age diseases approaching.How is midlife pictured in the book Life Reimagined?A.It can be quite rosy.B.It can be burdensome.C.It undergoes radical transformation.D.It makes for the best part of one's life.According to Karl Barth, midlife is the time .A.to relaxB.to matureC.to harvestD.to reflectWhat does the author say about midlife today？A.It is more meaningful than other stages of life.B.It is likely to change the narrative of one's life.C.It is more important to those with a longer lifespan.D.It is likely to be a critical turning point in one's life.

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D.

Most children with healthy appetites are ready to eat almost anything that is offered them and a child rarely dislikes food (51) it is badly cooked. The way a meal is cooked and served is most important and an (52) served meal will often improve a child’s appetite. Never ask a child whether he likes or dislikes a food and never (53) likes and dislikes in front of him or allow anybody else to do so. If the father says he hates fat meat or the mother refuses vegetables in the child’s hearing he is (54) to copy this procedure. Take it (55) granted that he likes everything and he probably will. Nothing healthful should be omitted from the meal because of a (56) dislike. At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once. Do not talk too much to the child (58) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food (59) he can hurry back to his toys.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
