4. automatic /ˌɔːtəˈmætɪk/ A. adj. 自动的; B. 无意识的; C. 必然的; D. n. 自动机械;自动手枪

题目解答

答案

我们来逐步分析这道题目。 题目给出一个英文单词:**automatic**,音标为 /ˌɔːtəˈmætɪk/,然后提供了四个选项: A. adj. 自动的 B. 无意识的 C. 必然的 D. n. 自动机械;自动手枪 这是一个考查单词 **automatic** 的词性、词义及用法的题目。 --- **第一步:分析单词的基本含义** 单词 **automatic** 最常见的词性是**形容词(adj.)**,其基本含义是: - **自动的**,指不需要人工干预就能运行的,比如:automatic door(自动门)、automatic transmission(自动变速器)。 所以,**A 选项“adj. 自动的”是 automatic 最核心、最常用的含义和词性,正确无疑。** --- **第二步:分析其他选项是否也正确** 我们逐个来看: **B. 无意识的** - automatic 确实在某些语境下可以引申为“无意识的”或“本能的”,比如: - He made an automatic response.(他做出了本能的反应。) - 这种用法仍然属于形容词,表示像机器一样自动发生的,引申为“无意识的”。 - 所以 **B 也有一定道理,是 automatic 的引申义之一**。 **C. 必然的** - 在某些逻辑或因果语境中,automatic 可以表示“必然产生的结果”,比如: - Failure is automatic if you don't study.(如果你不学习,失败是必然的。) - 所以“必然的”也可以看作是 automatic 的引申义,虽然不常见,但在特定语境下成立。 **D. n. 自动机械;自动手枪** - automatic 也可以作名词使用,尤其是在军事或机械领域: - an automatic(自动手枪) - a fully automatic(全自动枪械) - 所以 D 选项说它是名词,表示“自动机械”或“自动手枪”,**也是正确的用法**。 --- **第三步:题目类型判断** 题目没有明确说是单选还是多选,但从格式(A、B、C、D 四个选项)和常见题型来看,这很可能是一道**单选题**,要求选择**最准确或最常见**的释义。 虽然 B、C、D 都在特定语境下成立,但: - **A 选项“adj. 自动的”是 automatic 最基本、最核心的含义。** - 其他选项要么是引申义(B、C),要么是次要词性(D)。 而且,题目中给出的音标 /ˌɔːtəˈmætɪk/ 通常对应的是形容词发音,名词用法有时会强调重音差异(但实际中差别不大)。 --- **第四步:结论** 如果题目要求选择 **最恰当或最常见** 的解释,那么正确答案应是: > **A. adj. 自动的** 这是 automatic 的首要词性和定义。 --- **最终答案:** \boxed{A}

解析

本题考查单词 automatic 的词性、词义及用法。核心要点在于:

  1. 自动的是该词最基础、最常见的含义,属于形容词(adj.);
  2. 其他选项(无意识的、必然的、名词用法)均为引申义或次要用法;
  3. 需结合单选题特点,选择最直接、最常用的释义。

第一步:确认核心词义

automatic 的核心词义是 “自动的”,表示无需人工干预即可运行,如:

  • automatic door(自动门)
  • automatic washing machine(全自动洗衣机)

第二步:分析其他选项

B. 无意识的

  • 引申义:指行为像机器般本能、无意识,如:
    • automatic response(本能反应)
  • 属于形容词的扩展用法,但非主要含义。

C. 必然的

  • 逻辑语境中的引申义,如:
    • Failure is automatic if you skip steps(跳过步骤必然失败)
  • 使用频率较低。

D. 自动机械/自动手枪

  • 名词用法,常见于军事或机械领域,如:
    • automatic(自动手枪)
  • 词性与选项A不同(A为形容词,D为名词)。

第三步:题型判断

题目为单选题,需选择最准确的释义。A选项为形容词的核心含义,其他选项为引申义或次要词性,因此 A 是最优解。

  • 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.
