题目

_______, high pressure pipe and injectors need to be closely matched to provide optimum fuel injection. A The fuel injection pump B The fuel feed pump C The fuel transfer pump D The fuel booster pump

_______, high pressure pipe and injectors need to be closely matched to provide optimum fuel injection. 

A The fuel injection pump 

B The fuel feed pump 

C The fuel transfer pump 

D The fuel booster pump

题目解答

答案

解答:

题干的意思是:“_____,高压油管和喷油器需要紧密配合以提供最佳的燃油喷射。”

选项A,“The fuel injection pump”意为“燃油喷射泵”。燃油喷射泵是燃油供给系统中的重要部件,它的作用是将燃油从油箱中抽出并加压,然后通过高压油管输送到喷油器进行喷射。在这个过程中,燃油喷射泵、高压油管和喷油器需要紧密配合,以确保燃油的准确、高效喷射。因此,这个选项与题干中的“高压油管和喷油器需要紧密匹配”相呼应。

选项B,“The fuel feed pump”通常指的是向燃油系统提供燃料的泵,但它并不直接参与燃油的喷射过程,也不与高压油管和喷油器形成直接的配合关系。因此,这个选项与题干不符。

选项C,“The fuel transfer pump”意为“燃油输送泵”,它主要用于将燃油从一个地方输送到另一个地方,如从油箱输送到燃油喷射泵。虽然它也是燃油系统中的一个重要部件,但并不直接参与燃油的喷射过程,因此与题干中的描述不符。

选项D,“The fuel booster pump”并不是一个常见的汽车部件术语,且从字面意思上理解,它可能指的是一种增压泵,但并不特指燃油系统中的某个具体部件。因此,这个选项与题干不符。

综上所述,本题的正确答案是:A. The fuel injection pump。

  • 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.
