Why does the author say that e-learning is interactive? A. Because students can communicate with teachers, professors or other students in class. B. Because students can do homework any time. C. Because students can watch their teachers give lectures on video tapes.

题目解答

答案

我们来一步一步分析这道题目。 题目问的是:“为什么作者说电子学习(e-learning)是互动的?” 我们需要从三个选项中选择一个最能解释“e-learning 是 interactive(互动的)”的原因。 先来看每个选项的含义: **A. Because students can communicate with teachers, professors or other students in class.** 意思是:因为学生可以在课堂上与老师、教授或其他学生交流。 这个选项强调的是“交流”——这是“互动”(interactive)的核心特征。互动不仅仅是单向接收信息,而是有双向或多向的沟通。在电子学习中,很多平台提供讨论区、实时聊天、视频会议等功能,使学生和教师、学生和学生之间可以交流,这正是“互动”的体现。 **B. Because students can do homework any time.** 意思是:因为学生可以随时做作业。 这个描述的是“灵活性”(flexibility),而不是“互动性”。虽然这是e-learning的一个优点,但它并不直接说明“互动”。 **C. Because students can watch their teachers give lectures on video tapes.** 意思是:因为学生可以看老师讲课的录像。 这完全是单向的信息传递——学生只是观看,没有反馈或交流。这更像是传统的电视教学或录播课,缺乏互动元素。因此,这个选项不能解释为什么e-learning是互动的。 **结论:** 只有选项 A 提到了“交流”(communicate),这正是“interactive”的关键所在。 因此,正确答案是: \boxed{A}

解析

考查要点:本题考查对“e-learning(电子学习)”互动性的理解,需要结合选项判断作者认为e-learning互动的核心原因。

解题思路:

  1. 明确“interactive(互动)”的定义:互动强调双向或多向的交流与反馈,而非单向的信息接收。
  2. 对比选项:
    • 选项A提到“交流”,直接对应互动的核心特征。
    • 选项B强调时间灵活性,与互动无关。
    • 选项C描述单向的视频观看,属于传统单向教学形式。
  3. 关键结论:只有选项A体现了互动的本质。

选项分析

选项A

“Because students can communicate with teachers, professors or other students in class.”

  • 核心词:“communicate(交流)”直接对应“interactive(互动)”。
  • 逻辑:e-learning通过在线平台(如讨论区、视频会议)实现学生与教师、学生之间的实时或非实时交流,这是互动的关键表现。

选项B

“Because students can do homework any time.”

  • 问题:此选项强调“时间灵活”,但完成作业是单向行为(学生→系统),缺乏互动。
  • 排除理由:灵活性是e-learning的优点,但与“互动性”无关。

选项C

“Because students can watch their teachers give lectures on video tapes.”

  • 问题:观看录播视频是单向的信息接收(教师→学生),没有反馈或互动环节。
  • 排除理由:这与传统电视教学类似,属于单向传播,无法体现互动性。

最终结论:只有选项A明确体现了“互动”的核心特征。

  • 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.
