Does heavy use of cell phones pose a risk of cancer? This question has provoked controversy for many years. A new study in rats now adds to those concerns. Its data linked long-term, intense exposure to radiation from cell phones with an increased risk of cancer in the heart or brain. The results have yet to be confirmed, the authors note. Moreover, they add, it’s not yet clear what the findings may mean in terms of human health. Indeed, although the rat study found a link between cell-phone radiation and cancer, it offers no clues to why such a link might exist, notes Jonathan Samet. He teaches preventative medicine and directs the Institute for Global Health at the University of Southern California in Los Angeles. Still, he calls the new study’s findings “significant.” They could lead to studies probing how cell-phone radiation might cause cancer, he says. Phone signals are relayed between cell towers and cell phones via radio waves. This radiofrequency — or RF — radiation is a type known as non-ionizing. Unlike X-rays and alpha particles, non-ionizing radiation does not deposit enough energy into cells to release electrons from atoms or molecules, producing ions. So it tends to be far less harmful than ionizing radiation, such as X-rays. But that does not mean radio waves might not cause harm. In very large doses this radiation will heat the body and cause tissue damage. But it’s not yet known what much lower RF levels might do, such as those from cell-phone use. Five years ago, the World Health Organization’s International Agency for Research on Cancer, or IARC, concluded that cell-phone use “is possibly carcinogenic.” That means it might cause cancer. Its conclusion was based on what little research data were available at that time. But notice that IARC was not certain. It said only that phone use might “possibly” cause cancer. So scientists at the National Toxicology Program, or NTP, investigated further. The scientists exposed rats to the same types of radiation emitted by U.S. cell phones. The cancers in these rats resembled those seen in some human studies that had probed harm from cell phone use. For this reason, NTP says its findings appear to support IARC’s conclusion that heavy cell-phone use might be harmful.【小题】(1) In Jonathan Samet’s view, the new study in rats is very valuable because _________. A.it links cell phone radiation with an increased risk of cancer in the heart or brain B.it confirms the association between frequent use of cell phones and a risk of cancer C.it has found why heavy use of cell phones leads to an increase of risk of cancer D.it can push researchers to explore how radiation from cell phones leads to cancer 【小题】(2) Radiation from cell phones is comparatively safe in that __________. A.in fact it comes from X-rays B.it has nothing to do with ionizing C.it releases much electrons D.it doesn’t produce alpha particles 【小题】(3) According to IARC’s conclusion we may learn that __________. A.it’s very reasonable to use cell phones B.people should avoid using cell phones C.it deserves our caution to use cell phones D.we can use cell phones ignoring their harm
The fierce competitiveness of today's job market has driven one university dean to turn to online. He Hun, 39, the dean of Kunming University, has set up a store on Taobao where employers can glance over and buy the young graduates. He, the youngest university dean in China, hopes that his hold move will help students get on the career ladder. Mr He announced the formation of the online store at a graduation ceremony attended by 4,500 students and teachers on July 2. The Kunming University talent shop showcases (展示) the university's top 65 graduates, who each have an online personal file showing off their talent. All of the graduates are wearing white T-shirts bearing the Kunming University logo (校徽). The students are divided into four categories: along the way style, 2025 style, internet style and elite collection style. Clicking on each person's photograph reveals more about their character and skills. Students have also listed their career ambitions and preferred salaries. If a company is interested in hiring any of the graduates, they must pay the university 1,000 yuan to reserve the talent. The university will then verify the company's qualifications and arrange phone calls and video conversations between the future employers and employees. Whether or not a job offer is made, the university will return the money after a week. Mr He says he wants to use Taobao, which gets millions of views a month, to build a bridge between companies and students. His motto is "seek and you shall find." He says that this is just one of many new ideas he has for the university. According to the latest figures, around 7.49 million Chinese students will graduate from university this year. The figure is an increase of 220,000 on last year, and a new all-time high.【小题】(1) The purpose of He Hua's opening the talent store on Taobao is ________.A.to help employers find workersB.to help university graduates find jobsC.to make himself famousD.to show off his bold move【小题】(2) The employers can find a graduate's personal file by ________.A.ringing up the dean of Kunming UniversityB.clicking on the graduate's photographC.having a face-to-face interview with the graduateD.inquiring the graduate's tutor【小题】(3) Before arranging phone calls between its students and a company, what will the university do first?A.It will first check the company's qualifications.B.It will first have a face-to-face conversation with the company.C.It will pay the company 1,000 yuan for accepting the talent.D.It will arrange a video interview for the students to know about the company.【小题】(4) Where can we see this article?A.From a magazine.B.From an advertisement.C.From a diary.D.From a newspaper.

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.
question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

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.
