　　参考答案及解析：

　　1.The correct answer is B

　　Explanation

　　Choice (B) is correct. In climbing Mount Everest, Tom Whittaker was “bolstered,” or supported, by the type of physical preparation required to reach the summit of Mount Everest. “Assiduous,” or careful and persistent, preparation coupled with “unflagging determination” would help someone complete such a challenging task.

　　2.The correct answer is D

　　Explanation

　　The word “merely” indicates that the past provisions were not as strict as the “mandatory” provisions and “recommended” is the only first term that conveys a lesser degree of strictness. Only “violators” could logically be penalized by losing their federal research grants.

　　3.The correct answer is D

　　Explanation

　　The jellyfish is presented as seeming the opposite of harmful. Only “harmless” fits the logic required by “but.”

　　4.Yep! That's right.

　　Explanation

　　Choice (E) is correct. Bickering is the kind of petulant or peevish arguing to which personal dislike might have led the speakers, but their “accord,” or agreement, on substantive issues kept them from squabbling.

　　5.The correct answer is B

　　Explanation

　　Choice (B) is correct. The structure of the sentence indicates that the word that fills in the blank will be explained by the part of the sentence that follows the colon. We are told that Gordon Parks adapted the screenplay for The Learning Tree "from his own novel," wrote music for the film, and directed the film. Because of his involvement in several different aspects of the film, it makes sense to describe Parks as "protean," or demonstrating great variety and diversity.
