题目内容
8.With the task set,the agricultural scientists _______ their research work at once.( )A. | began | B. | had begun | C. | were beginning | D. | have begun |
分析 任务已经确立,这些农业科学家立刻开始了他们的研究.
解答 答案是A.考查时态,根据句意"任务已经确立,这些农业科学家立刻开始了他们的研究."这是对于发生了的一件事情的一般性的描述,所以句子用一般过去时表达最佳,故答案选A.
点评 动词时态的考点是近几年高考试题考查的重中之重.各地高考试题对动词时态的考查越来越侧重于语境化、交际化的理解,这加大了试题的难度,没有明确的时间状语,这就要求考生对句子的语境进行正确的判断,从而选出正确的时态.
