Halley's Comet (慧星) completed its latest trip around the Earth in 1986. It is now speeding toward the far-distant edges of our solar system. People on Earth will not be able to see it again until 2062. Scientists in many countries waited and prepared for years for the return of Halley's Comet. They planned new ways to observe the comet as it came near the Earth.Comets are of great interest to scientists. This is because the space objects are believed to have changed very little since the solar system was formed 4,600 million years ago. Scientists believe that if they can learn more about the elements in a comet, they will understand more about conditions when the solar system was new.Halley's Comet is probably the most famous comet. Historians say it was first noted about 2,200 years ago. The visit of the bright space object has been observed and recorded every 76 years since then. The comet was named after British scientist Edmund Halley. In the early 1700s, Halley studied records of the appearance of huge balls of fire flying across the sky. And he studied the sky to make his own observations. Halley was the first person to recognize that the balls of fire were really the same bright object, a comet. Halley said the comet circled the sun just as the planets did. And he said the comet's trip around the sun took about 76 years.Since the discoveries by Edmund Halley, people have waited for that bright comet to return. When it came, people looked at it through small telescopes (望远镜) they held in their hands. And scientists looked at it through huge telescopes placed on top of mountains where the air was clear. But the most recent visit of Halley's Comet was the first time scientists could study the comet up very close. They did this through scientific instruments sent into space.(1) (单选题)Halley's Comet is ________.A.a planetB.fire in spaceC.a starD.a bright space object(2) (单选题)Which is the best topic of this passage?A.What Is a Comet?B.Halley's CometC.The Discovery of Halley's CometD.How Halley's Comet Was Discovered(3) (单选题)Scientists are interested in comets in that ________.ets are bright space objectsB.people will not be able to see them until 2062C.they believe that if they can learn more about the elements in a comet, they will understand more aboutD.the space objects are believed to have changed very little since the solar system was formed 4,600 million(4) (单选题)The most recent appearance of Halley's Comet was different because scientists could study the comet using ______________.A.instruments sent into spaceB.telescopes they held in their handsC.huge telescopes on top of mountainsD.space stations that could get them very close(5) (单选题)Which of the following statements is NOT true?A.People will be able to see Halley's Comet in 2062.B.Halley's Comet was first noted about 2,200 years ago.C.Halley's Comet was named by British scientist Edmund Halley.D.Halley's Comet circles the sun.
Robots could fill the jobs of 3.5 million people in Japan by 2025, a think-tank says, helping to alleviate worker shortages as the country's population shrinks.Japan faces a 16 per cent drop in the size of its workforce by 2030 while the number of elderly will mushroom, the government estimates, raising worries about who will do the work in a country unused to, and unwilling to think seriously about large-scale immigration.The think-tank, the Machine Industry Memorial Foundation, says robots could help fill the gaps, ranging from micronized capsules that detect problems to high-tech vacuum cleaners. Rather than each robot replacing one person, the foundation said in a report that robots could make time for people to focus on more important things.Japan could save 2.1 trillion yen (10.4 billion pounds) of elderly insurance payments in 2025 by using robots that monitor the health of older people, so they do not have to rely on human nursing care, the foundation said in its report. Caregivers would save more than an hour a day if robots helped look after children, older people and did some housework. Robotic duties could include reading books out loud or helping bathe the elderly."Seniors are pushing back their retirement until they are 65 years old, day care centers are being built so that more women can work during the day, and there is a move to increase the quota of foreign laborers. But none of these can beat the shrinking workforce," said Takao Kobayashi, who worked on the study. "Robots are important because they could help in some ways to relieve such shortage of the labor force."The current fertility rate is 1.3 babies per woman, far below the level needed to maintain the population, while the government estimates that 40 percent of the population will be over 65 by 2055, raising concerns about who will look after the graying population.Kobayashi said changes were still needed for robots to make a big impact on the workforce. "There's the expensive price tag, the functions of the robots still need to improve, and then there are the mindsets of people," he said. "People need to have the will to use the robots."1. What is the main idea of this passage?A) Robots will play a very important role in society.B) Robots can relieve shortage of the labor force. C) Robots will change people's life style.D) Robots can save time for people.2. Which of the following best describes what robots could do in the future?A) They could be high-tech vacuum cleaners.B) They could take care of children and older people.C) They could monitor the health of older people.D) They could do various things to make time for people. 3. It can be inferred from the fifth paragraph that ________.A) delaying seniors' retirement can solve the problem of worker shortageB) women will get better job in big companyC) foreign laborers can beat the shrinking workforceD) using the robots is the best way to alleviate worker shortage 4. Which of the following statements is NOT true?A) Japan faces the problem of workforce shrinkage.B) The number of older people will increase rapidly.C) Using robots can save money and time for people.D) Half of the population will be over 65 in 2055. 5. Among the things we should do, which is NOT implied in the last paragraph?A) Lower robots' price.B) Improve robots' functions.C) Produce more robots. D) Change our ways of thinking about robots.

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. Under (60) circumstances must a child be coaxed or forced to eat.55（）。A. withB. asC. overD. for

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.

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.
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. When the product quality is below standard.
