An American study has shown a link between activity on the surface of the sun and weather conditions on Earth. Scientists say small changes in the sun's brightness can produce effects on Earth similar to two weather events in warm waters of the Pacific Ocean. The two events are commonly known as La Nina and El Nino. Reports say the study may lead to better predictions of temperatures, rainfall and the intensity of weather systems.Scientists measure solar activity by counting dark areas on the sun's surface. These sun spots produce bursts of energy. Other scientists have shown that sun spot activity can be measured in periods of time that last about eleven years. The total energy reaching Earth from the sun rises and falls by just one tenth of one percent across this solar cycle.In the new study, scientists examined more than one hundred years of ocean temperature records. They also used computer programs designed to reproduce the world's climate. They found the highest levels of solar activity cause small, but far-reaching effects on weather systems around the world. These periods of high activity are known as solar maximum.Gerald Meehl was the lead writer of a report about the study. He says his team showed the effects of a new process to understand what happens in the Pacific's warm waters where there is a maximum of solar activity. Professor Meehl works for the National Center for Atmospheric Research in Boulder, Colorado. The center organized and helped to pay for the study. The findings were published recently in the Journal of Climate.The report says that, at maximum activity, the small increase in sunshine over several years causes a small temperature increase in Earth's atmosphere. This is especially true in cloud-free areas of the Pacific.The extra heat is enough to cause ocean waters to evaporate(蒸发)into the air. This wet air is then carried by trade winds to the normally rainy areas of the western Pacific, near the Equator(赤道). This creates more rainfall. The trade winds become stronger as the process gets repeated. This keeps the eastern Pacific cooler and drier than normal. (1)What may people get from the American study mentioned in the passage?

C.More precise predictions of the climate and the intensity of weather system. D.Two events known as La Nina and Ei Nino in warm waters of the Pacific Ocean.

English words are usually formed in four ways:- affixation (词缀法) including prefixation (前缀法), such as impossible, rewrite, and suffixation (后缀法), such as useful, visually, pursuer, motivation;- compounding (合成法), such as software, well-known, 3-year-old;- abbreviation (缩略法), such as DI, USA;- conversion (词性转换法).Conversion is done when a word changes its class without any change of its form. Its typical (典型的) cases include noun → verb, verb → noun, adjective → noun and adjective → verb, such astutor n. → v. change v. → n. red adj. → n. lower adj. → v.In the text there are some words used in the same way.

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 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.
