The sun is losing its spots, and it’s certainly something that we shouldn’t take lightly. According to news from a famous Australian website, our fireball has gone blank for the second time this month, leading Meteorologist Paul Dorian to believe that the next solar minimum is approaching and there will be an increasing number of spotless days over the next few years. This matters because the amount of sunspots reportedly affects our climate.What is solar minimum exactly? NASA explains it to be when the sun’s natural solar cycle shows the lowest amount of sunspots and the sun is at its worst. When at its best, the sun’s surface is covered in visible dark stains, or sunspots. The sun goes through a natural solar cycle approximately every 11 years, and each cycle is marked by the increase and decrease of sunspots—with the highest number of sunspots in any given solar cycle being the “solar maximum” and the lowest number being “solar minimum.” Cycles span from one maximum to the next.“In the years around 2000-2001, the Solar Max once took place. During Solar Max, huge sunspots and intense solar flares (太阳耀斑) are a daily occurrence. It’s a good time for sky watchers who enjoy auroras (极光), but not so good for astronauts who have to be cautious of radiation storms. Power outages, telecommunication disruptions, and GPS receiver failure are just a few of the things that can happen during a solar maximum”, NASA said Wednesday, and went on to explain that “during solar minimum, the opposite occurs. Solar flares are almost non-existent while whole weeks go by without a single, tiny sunspot to break the sameness of the blank sun. This is what we are experiencing now.”Dorian breaks down all of the sun-related information in his report, published just a few days ago. “The blankness will stretch for just a few days at a time, then it’ll continue for weeks at a time, and finally it should last for months at a time,” says Dorian, leading a lot of us to believe that the next mini ice age is on its way.1. Why should people be aware that the sun is losing its spots?A) Because numerous spotless days are coming.B) Because the next solar minimum is approaching.C) Because the sunspots influence the earth’s climate. D) Because the sun has become a fireball twice this month.2. What do we know about the solar cycle?A) It refers to the lowest amount of sunspots.B) It is marked with the highest number of sunspots.C) It is the periodic 11-year change of the sun’s activity. D) It refers to the quantitative change of sunspots in certain years’ time.3. What do we know about the solar maximum?A) It has no impact on astronauts inspecting radiation storms.B) During a solar maximum, huge sunspots occur every day. C) It is a good time for sky watchers to watch the sky and stars.D) Telecommunication and GPS can work well during a solar maximum.4. What would happen during the solar minimum according to the NASA?A) Solar flares would occur every week.B) The sun would become blank for years.C) No sunspot would occur during the whole weeks. D) Power plant and GPS would fail to work properly.5. According to Dorian’s report, what might happen in the near future?A) Solar flares will be almost non-existent.B) The sun will become smaller and smaller.C) The world will be getting colder and colder. D) The number of sunspots will keep increasing.

  • 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.
