阅读理解 The Chinese Antarctica expedition returned to Shanghai last Friday following a month living on the ice．It was the First time Chinese scientists had visited the Amery Ice Shelf?the longest ice shelf in the world．The team collected ice samples and data on temperatures, which are necessary for research on global warming．So far, about 27 countries have visited Antarctica for scientific research．Although the living conditions are very hard, many scientists have to stay there for long periods of time．So, how do they manage their lives on the ice? During the summer, the temperature in Antarctica reaches about －20℃．It falls to about －60℃ in winter．So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes to protect them from the cold．These clothes include jeans, running shoes, jackets, long underwear, boots and woolen socks．Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is －30℃．Natural protection such as facial hair can also help．"That's why many researchers wear a beard．It really does keep you warm, " says German explorer Arved Fuchs． Usually, the polar researchers have good meals．Some even have feasts on holidays like Christmas and New Year's Day．Vegetables are always welcomed and usually finished the quickest．Life on the ice means living with other researchers in tight living spaces．Most people sleep in dormitory．More remote field camps use separate tents．So．at least some researchers don't have to put up with annoying snorers ． (1) Why did researchers visit Amery Ice Shelf? [ ] A． Because Amery Ice Shelf is the largest and most typical ice shelf． B． Because they wanted to challenge themselves in extreme climate． C． Because they desired to collect ice samples and data to study global warming． D． Because they were curious of the living conditions there． (2) What is the matter that researchers care most for living in Antarctica? [ ] A． Taking advantage of rare sunshine B． Putting up with annoying bears C． Having access to rich food D． Protecting themselves from coldness (3) What most describes the living space of most researchers on the Amery Ice Shelf? [ ] A． Small B． Changing C． Remote D． Unbearable (4) What does the underlined word of "snorers" mean? [ ] A． Those who wear a beard B． Those who like to do research on their own C． Those who have vegetables as their main food D． Those who breathe roughly and noisily while sleeping

【阅读理解】阅读文章选出正确的答案。 It used to be so straightforward. A team of researchers working together in the laboratory would submit the results of their research to a journal. A journal editor would then remove the author’s names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal. No longer, The Internet---and pressure from funding agencies, who are questioning why commercial publishers are making money from government--funded research by restricting access to it---is making access to scientific results a reality. The Organization for Economic Co-operation and Development (OECD) was just issued a report describing the far-reaching consequences of this. The report, by john Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor. The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market if estimated at between 7 billion and II billion. The International Association of Scientific, Technical and Medical publishers says that there are more than 2,000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16,000 journals. This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three ones were identified by the report's author. There is the so-called big deal, where institutional subscribers pay for access to a collection of online journal titles through site licensing agreements. There is open-access publishing, typically supported by asking the author (or his employer)for the paper to be published. Finally, there are open-access archives, where originations such as universities of international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form of the peer-review process, at least for the publication of papers.一、 In the first paragraph, the author discusses____. A、the background information of journal editing. B、the publication routine of laboratory reports. C、the relations of authors with journal publishers. D、the traditional process of journal publication. 二、 Which of the following is true of the OECD report? A、It criticizes government-funded research. B、It introduces an effective means of publication. C、It upsets profit-making journal publishers. D、It benefits scientific research considerably. 三、 According to the text, online publication is significant in that____. A、it provides an easier access to scientific results. B、it brings huge profits to scientific researchers. C、it emphasizes the crucial role of scientific knowledge. D、it facilitates public investment in scientific research. 四、 With the open-access publishing model, the author of a paper if required to____. A、cover the cost of its publication. B、subscribe to the journal publishing it. C、allow other online journals to use it freely. D、complete the peer-review before submission. 五、 Which of the following best summarizes the main idea of the passage? A、The Internet is posing a threat to publishers. B、A new modal of publication is emerging. C、Authors welcome the new channel for publication D、Publication is rendered easier by online service

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.

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 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.
