POLAR bears have patrolled the planet’s icy regions for millions of years longer than previously thought – riding out several episodes of global warming in that time. While this suggests their future might not be so bleak, it is no guarantee they will survive the melting occurring in the polar regions today.Charlotte Lindqvist of the University at Buffalo, New York, and an international team of researchers have just completed the most comprehensive analysis yet of the polar bear genome (基因组). The team looked at DNA from 23 living polar bears and a 110,000-year-old polar bear jawbone. Aided by comparisons with the genomes of brown and black bears, they found that polar bears first emerged as a separate species between four and five million years ago. Previous studies had suggested the species didn’t diverge (分化) from brown bears until much later – perhaps just 600,000 years ago.The analysis also showed that polar and brown bears have sometimes interbred (杂交) since their initial divergence, and that populations of polar bears have been changing over the past million years in accordance with the climate. Polar bear numbers dropped during warm periods but bounced back with prolonged ice ages – most noticeably during a period of cooling between 800,000 and 600,000 years ago. The population looks set to fall again as melting pack ice forces polar bears back to the land-based habitats (栖息地) of brown bears, where interbreeding has recently been observed. Should extensive interbreeding occur, both polar and brown bear populations could decline with the emergence of a new hybrid (杂交的) species.Lindqvist says that the analysis reveals that polar bear DNA has lost diversity as population has decreased, drifted apart and become genetically isolated, suggesting today’s bears have less adaptability to the environmental change, habitat loss, pollution and diseases they now face.Earlier this year, Frank Hailer of the Biodiversity and Climate Research Centre in Frankfurt, Germany, and colleagues estimated that polar bears diverged from brown bears 600,000 years ago – a result that itself pushed back the evolutionary record of polar bears by about 450,000 years. However, Hailer says that the new results broadly are consistent with his team’s findings, which also suggested that polar bears may have evolved much earlier than the 600,000 year mark.1. What is the closest meaning of the phrase “riding out” (Para.1)?A) Skyrocketing.B) Seesawing.C) Surviving. D) Substituting.2. What was found in the research of polar bear genome according to the passage?A) Polar bears appeared as a separate species much earlier than we had thought. B) The DNA of living polar bears is very similar to that of a 110,000-year-old polar bear.C) Polar bears have survived the icy ages and will also survive the melting today.D) Polar bears diverged from brown bears perhaps just 600,000 years ago.3. When would populations of polar bears drop over the past million years according to the passage?A) When the climate became colder.B) After the initial divergence between polar and brown bears.C) During a period between 800,000 and 600,000 years ago.D) When polar bears were forced back to the land-based habitats. 4. Why are the polar bears today less able to adapt themselves to the environment according to the passage?A) Because polar bears are isolated and cannot find new habitats.B) Because polar bears are facing more difficulties nowadays.C) Because the DNA of polar bears has lost diversity. D) Because the interbreeding with brown bears has produced a new hybrid species.5. What can be inferred from this passage?A) Brown bear populations may increase, while polar bear populations decline.B) We are not sure that polar bears will survive the melting of polar regions.C) A new hybrid species of polar bears will have more adaptability to the environmental changes. D) The polar bear populations would increase when they began to interbreed with brown bears.

First we had BSE (疯牛症); then we had Foot and Mouth followed by bird flu; and now there is another food scare—this time involving pigs. Anyone who has bought Irish bacons, sausages or other pork products over the past two months has been told to destroy them amid fears they could be poisoned. Ireland's Food Safety Authority is recalling all pork products made in the country since 1 September because super high levels of dioxins (二恶英) have been found at nine farms across Ireland; some are as much as 200 times the recommended amount. It's thought it contaminated animal feed, and which may be sold to more than 40 farms is to blame. The main message to consumers is if you have any Irish pork products in your fridges, get rid of them. But don't panic. The risk here isn't thought to be great. Dioxins are harmful if you are exposed to them over a long period of time, but as this outbreak (突发事件) only started two months ago, the danger is very slight. Plus the UK gets most of its pork products from countries other than Ireland. So, the amount of affected meat on the market here is small. It's a different story in Ireland though. Britain may not rely on Irish pork but the UK is still one of Ireland's biggest customers. Not only that, all bacons, hams, sausages and even things like meat pies have to be destroyed. And it could cause disaster for Ireland's 400 pig farmers in the period of time before Christmas. Their representatives insist this scare affects less than ten percent of the products on the market at the moment; and that all meat produced from now on will be perfectly safe. Still, it's likely to destroy consumer confidence on both sides of the Irish Sea at one of the most important times of year for the meat industry.1. Why were people asked to destroy Irish meat products?A) Because they try to avoid infection of BSE, Foot and Mouth and bird flu.B) Because they try to reduce the direct and indirect danger of swine flu.C) Because they try to reduce the possibility of eating poisonous meat food. D) Because they try to follow the command of the government.2. What caused Ireland's Food Safety Authority to recall pork products?A) The animal feed has been polluted by the producing companies.B) The pork from 49 farms was all found with high levels of dioxins.C) The pork products made in Ireland since 1 September were possibly poisonous. D) The dioxins in pork are as much as 200 times the allowed amount.3. Which of the following statements is true according to the passage?A) Some people get sick after eating food with dioxins for several days.B) It is not sure the danger of food is harmful to human's health.C) The polluted meat only occupied a small quantity of the market. D) The UK decides to import the pork products from other countries.4. What is the influence on Ireland?A) There are few meat products sold on the market.B) Its 400 pig farmers hardly prepare for the Christmas Day.C) Most of the meat companies nearly go bankrupt.D) Its export of pork products has got heavy losses. 5. Which of the following can we infer from the passage?A) Farmers should feed healthier pigs.B) Today's food is not safe to us anymore.C) All meat produced from now on will be perfectly safe.D) People probably have less confidence in the meat industry.

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.

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.

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
