题目解答

答案

我们来一步一步分析这道题: --- ### 题目翻译: **“______散货船受到巴拿马运河船闸闸室的严格限制。”** 英文原文是: **"Bulk carriers are strictly restricted by the lock chamber of the Panama Canal."** --- ### 问题分析: 题目是在问哪一种**散货船**(bulk carrier)会受到**巴拿马运河船闸尺寸**的限制。 --- ### 各选项分析: #### A. 苏伊士型(Suezmax) - 这类船的大小是根据**苏伊士运河**的通航限制设计的。 - 与**巴拿马运河**的限制无关。 ✅ **排除** #### B. 好望角型(Capesize) - 指的是**无法通过苏伊士运河**的大型散货船,必须绕行好望角。 - 通常这类船体型巨大,**也通不过巴拿马运河**。 - 但题目中强调的是“受到巴拿马运河船闸的限制”,而**Capesize船通常根本不会尝试通过巴拿马运河**。 ✅ **排除** #### C. 巴拿马型(Panamax) - 这类船是专门为通过**巴拿马运河**而设计的,其尺寸正好符合运河船闸的最大限制。 - 所以说“受到巴拿马运河船闸的严格限制”正是这类船的特点。 ✅ **符合题意,是正确答案** #### D. 超大型(Super bulker) - 这是一个泛称,指非常大的散货船,通常超过Panamax级别。 - 一般无法通过巴拿马运河,但题目中没有明确指向这类船。 ✅ **不如C选项准确,排除** --- ### 正确答案: $$ \boxed{C} $$ --- ### 总结: 本题考查的是对不同类型散货船与运河通航限制关系的理解。**Panamax**(巴拿马型)散货船是专门为适应巴拿马运河船闸尺寸而设计的,因此会受到该限制。

解析

本题考查散货船类型与运河通航限制的关系,核心在于理解不同船型的设计依据。关键点在于:

  1. 巴拿马运河的船闸尺寸直接影响特定船型的定义;
  2. Panamax(巴拿马型)是唯一专门为适应巴拿马运河而设计的船型;
  3. 其他选项如苏伊士型、好望角型、超大型散货船均与巴拿马运河的限制无直接关联。

选项分析

A. 苏伊士型(Suezmax)

  • 设计依据:苏伊士运河的通航限制。
  • 与题目无关:题目问的是巴拿马运河,因此排除。

B. 好望角型(Capesize)

  • 特点:体型过大无法通过苏伊士运河,需绕道好望角。
  • 隐含矛盾:此类船通常也无法通过巴拿马运河,但题目强调“受船闸限制”,而Capesize船一般不会尝试通过巴拿马运河,排除。

C. 巴拿马型(Panamax)

  • 核心定义:专为巴拿马运河船闸的最大尺寸设计。
  • 直接对应:题目中“严格受限于巴拿马运河船闸”正是Panamax的典型特征,因此正确。

D. 超大型散货船(Super bulker)

  • 特点:超过Panamax尺寸,无法通过巴拿马运河。
  • 间接性:题目未明确指向此类船,且选项C更直接,排除。

  • 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.
