"这份文档是针对GRE、CAT和GMAT考试的1853个最难词汇列表,旨在帮助备考者扩展词汇量。每个单词以粗体形式给出,其含义紧跟在等号 (=) 之后。此外,对于英式拼写与美式拼写不同的单词,会在括号内标注‘BRITISH’并提供英式拼写,如‘belabor’(英式拼写为‘belabour’)。" 这个词汇列表是备考GRE、CAT和GMAT的考生的重要参考资料。GRE是美国研究生入学考试,考察批判性思维、阅读理解、数学和写作能力;CAT是印度管理学院的入学考试,测试定量能力、语言和逻辑推理;GMAT则是全球广泛接受的商科研究生入学考试,侧重评估分析写作、定量、阅读和口语技能。 在准备这些考试时,掌握大量的词汇对于提升阅读理解能力和写作水平至关重要。例如,'belabor' 或 'belabour' 表示过分讨论或反复强调,这在写作中可以用来表达批判性的观点。'amphitheater' 或 'amphitheatre' 指的是环形剧场,可能会出现在描述历史或文化背景的题目中。'anathema' 意味着诅咒或禁止,可能在讨论宗教或道德议题时出现。 'annul' 意为取消或使无效,这在法律或合同相关的讨论中会用到。'anodyne' 指的是止痛药,可能出现在医学或健康话题中。'anoint' 有圣化或涂抹油(尤其作为神圣仪式)的含义,常关联于宗教仪式。'anonymity' 表示匿名状态,对于隐私和信息安全的话题非常重要。 'antediluvian' 意为远古的、过时的或史前的,用于描述古老文明或观念。'antithesis' 是直接对立的意思,可用于哲学或辩论中的对比分析。'apathetic' 描述无动于衷或漠不关心的态度,常见于心理学和社会行为的讨论。'aphasia' 是失语症,涉及神经科学和医学领域。'aphorism' 是格言或老生常谈,可能出现在文学或智慧主题中。 'aplomb' 指的是沉着自信,是描述个人特质或领导力的重要词汇。而 'apocryphal' 则表示可疑的真实性,常用于历史或传说故事的讨论中,判断其是否真实可信。 这份词汇列表涵盖了广泛的主题,对备考者来说是一份宝贵的资料,它不仅能够提高他们的词汇量,还能帮助他们理解和使用这些高级词汇,从而在考试中取得更好的成绩。

(Telephone Number Word Generator) Standard telephone keypads contain the digits 0 through 9. The numbers 2 through 9 each have three letters associated with them, as is indicated by the following table: Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers. For example, a person whose telephone number is 686-2377 might use the correspondence indi- cated in the above table to develop the seven-letter word “NUMBERS.” Businesses frequently attempt to get telephone numbers that are easy for their clients to remember. If a business can advertise a simple word for its customers to dial, then no doubt the business will receive a few more calls. Each seven-letter word corresponds to exactly one seven-digit telephone number. The restaurant wishing to increase its take-home business could surely do so with the number 825-3688 (i.e., “TAKEOUT”). Each seven-digit phone number corresponds to many separate seven-letter words. Unfortunately, most of these represent unrecognizable juxtaposi- tions of letters. It’s possible, however, that the owner of a barber shop would be pleased to know that the shop’s telephone number, 424-7288, corresponds to “HAIRCUT.” A veterinarian with the phone number 738-2273 would be happy to know that the number corresponds to “PETCARE.” Write a C++ program that, given a seven-digit number, writes to a file every possible seven-letter word corresponding to that number. There are 2187 (3 to the seventh power) such words. Avoid phone numbers with the digits 0 and 1.
