解析

本题主要考查不同时态的用法,包括一般过去时、现在完成时、过去进行时、过去将来时等。解题的关键在于根据句子中的时间状语来判断应该使用的时态。

第1题

  • 题目中“a moment ago”是一般过去时的时间标志词,这表明句子的动作发生在过去。
  • 主语“He”是第三人称单数,在一般过去时中,be动词要用“was”。所以应该选A。

第2题

  • “so far”表示“到目前为止”,是现在完成时的典型时间状语。
  • 现在完成时的结构是“have/has + 过去分词”,主语“They”是复数,所以用“have”,“donate”的过去分词是“donated”,即“have donated”。因此选C。

第3题

  • “yet”常用于现在完成时的疑问句中。
  • 现在完成时的一般疑问句结构是“Have/Has + 主语 + 过去分词”,“have”的过去分词还是“had”,所以是“Have; had”。故答案选B。

第4题

  • 主句“She was very happy”用的是一般过去时,从句的动作“赢得一等奖”发生在主句动作之前,即“过去的过去”,要用过去完成时。
  • 过去完成时的结构是“had + 过去分词”,“win”的过去分词是“won”,也就是“had won”。所以选D。

第5题

  • “at that time”表示过去某个具体的时间点,句子的动作在这个时间点正在进行,要用过去进行时。
  • 过去进行时的结构是“was/were + 现在分词”,主语“She”是第三人称单数,用“was”,“sing”的现在分词是“singing”,即“was singing”。因此选A。

第6题

  • 主句“He said”是一般过去时,从句的动作“买新车”发生在主句动作之后,即“过去的将来”,要用过去将来时。
  • 过去将来时的结构是“would + 动词原形”,所以是“would buy”。故答案选B。

第7题

  • “just now”是一般过去时的时间标志词,说明句子的动作发生在过去。
  • “lock”的一般过去式是“locked”。所以选C。

  • 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.

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
