题目内容
4.The organization ______ thousands of homeless animals since last year.( )| A. | has saved | B. | saved | C. | was saving |
分析 自从去年以来,这个组织已经挽救了成千上万个流浪动物.
解答 答案:A.
根据时间状语since last year结合句意"自从去年以来,那个组织已经挽救了成千上万个流浪动物."判断用现在完成时.现在完成时的构成是:主语+have/has+动词的过去分词;主语是单数名词,助动词用has,故答案为A.
点评 本题考查了动词的时态.做题时,一定要特别关注有关的时间短语,这是判断句子时态的标志.在没有时间状语的情况下可以联系上下文根据语境来做出正确判断.
