D. not; but

题目解答

答案

### 问题解析 这道题考察的是连词的使用,特别是用于连接两个并列成分的连词短语。我们需要选择一个合适的连词短语来连接“3D models”和“3D organs for operations”,使句子通顺且意义完整。 ### 选项分析 - **A. either; or** - 意思是“或者……或者……”,表示选择关系。例如:“You can either go to the party or stay at home.”(你可以要么去参加派对,要么待在家里。) - 用在这个句子中,意思会是“普通的打印机可以打印3D模型或者3D器官用于手术”,这在逻辑上是合理的,但通常“either; or”用于表示选择,而不是并列关系。 - **B. neither; nor** - 意思是“既不……也不……”,表示否定关系。例如:“He neither likes coffee nor tea.”(他既不喜欢咖啡也不喜欢茶。) - 用在这个句子中,意思会是“普通的打印机既不能打印3D模型也不能打印3D器官用于手术”,这与句子的意图不符,因为句子的意图是表达打印机的能力,而不是不能做什么。 - **C. not only; but also** - 意思是“不仅……而且……”,表示递进关系。例如:“She not only speaks English but also French.”(她不仅会说英语,还会说法语。) - 用在这个句子中,意思会是“普通的打印机不仅能够打印3D模型,而且能够打印3D器官用于手术”,这在逻辑上是合理的,表达了打印机的多功能性。 - **D. not; but** - 意思是“不是……而是……”,表示对比关系。例如:“He is not a teacher but a doctor.”(他不是老师,而是医生。) - 用在这个句子中,意思会是“普通的打印机不能打印3D模型,而是打印3D器官用于手术”,这在逻辑上不太合理,因为句子的意图是表达打印机的多种功能,而不是对比。 ### 最佳选择 根据句子的意图和逻辑,最佳选择是 **C. not only; but also**,因为它能够准确地表达普通打印机的多功能性,即不仅能够打印3D模型,还能够打印3D器官用于手术。 ### 最终答案 **C. not only; but also**

解析

本题考查连词短语的用法,重点在于根据句意选择合适的连接词。句子需要表达普通打印机的两种功能,即打印3D模型和用于手术的3D器官,因此需要体现递进或并列关系的连词。解题关键在于理解句意的逻辑关系,排除不符合语境的选项。

句意分析:句子要表达普通打印机的双重能力,即既能打印3D模型,又能打印3D器官用于手术。因此,需要选择能连接两个并列且递进关系的连词短语。

选项分析:

  1. A. either; or

    • 表示选择关系(“或者……或者……”),强调两者选其一。
    • 若选此选项,句意变为“打印机只能选择打印3D模型或3D器官”,与原句“同时具备两种功能”矛盾。
  2. B. neither; nor

    • 表示否定关系(“既不……也不……”),用于否定两个事物。
    • 若选此选项,句意变为“打印机不能打印3D模型和器官”,与原句意图完全相反。
  3. C. not only; but also

    • 表示递进关系(“不仅……而且……”),强调两种功能的并存和递进。
    • 完全符合句意,突出打印机的“多功能性”。
  4. D. not; but

    • 表示对比关系(“不是……而是……”),强调否定前项、肯定后项。
    • 若选此选项,句意变为“打印机不能打印3D模型,而是打印器官”,与原句“同时具备两种功能”矛盾。

结论:C选项最符合句意,正确连接两个并列且递进的功能描述。

  • 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.

  • 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. When the product quality is below standard.

  • 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.
