Scientists often compare coral reefs(珊瑚礁)to underwater rainforests,yet unlike the leafy plant base of a forest,corals are animals.The soft creatures are naturally half-transparent and get their brilliant color from algae(藻类)living inside them.When corals experience stress from hot temperatures or pollution,they halt the interdependent relationship with algae,typically pushing them out and turning white.Corals are still alive when they are white,but they're at risk and many eventually die,turning dark brown. Scientists around the world are looking for means to protect and maybe increase corals.One common option is to create more protected areas — essentially national parks in the ocean.Beyond nature preserves,some conservationists are looking to more hands-on methods.One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining.The reef system in the Keys has been hit hard by climate change and pollution,which is especially tough,because corals there help support fisheries worth $100 million every year. To keep the wild ecosystem alive,Erinn Muller,the center's director,and her team are harvesting samples of the corals that survived the environmental stress naturally,keeping them to make them reproduce,and then reattaching them to the reef.They have 46,000 corals on plastic frames under the sea.So far,the center has regrown over 70,000 corals from five different species on damaged reefs. In The Bahamas,Ross Cunning,a research biologist at Chicago's Shedd Aquarium,focuses on corals with genes that could make them natural candidates for restoration projects.He published a study of two Bahamian reefs,one that survived an extreme 2015 heat wave,and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning.There's evidence of corals evolving more quickly to resist rapidly warming climate.The big question scientists need investigate,adds Cunning,is how much more heat corals can adapt to.(1)What does the underlined word "halt" in the first paragraph mean? ____ A.End.B.Develop.C.Strengthen.D.Weaken.(2)What do Muller and her team do to save corals? ____ A.Restore the damaged reefs.B.Grow corals by hand underwater.C.reate more protected areas.D.Move corals to unpolluted areas.(3)What do Cunning's words suggest? ____ A.Many corals have been genetically improved.B.Cooling down the waters is key to rescuing corals.C.Reasons for corals surviving heat waves are shocking.D.The highest temperature corals can survive is unclear.(4)Which can be a suitable title for the text? ____ A.Relationship between corals and algaeB.Efforts made to save coralsC.Impact of climate warming on coralsD.Survival crisis faced by coral reefs

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

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.

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.
