题目内容
20.The number of Chinese weibo users _________ 250million so far.( )| A. | has reached | B. | reached | C. | will reach | D. | reach |
分析 到目前为止,中国微博用户的数量是25千万.
解答 答案:A
根据so far可知,从过去到目前为止,是一段时间,表示过去的动作一直持续到现在,所以用现在完成时态,现在完成时态的结构为have/has+动词的过去分词,主语是The number of Chinese weibo users是单数形式,表示"…的数量",所以助动词用has,故选A.
点评 本题主要考查现在完成时,用法:表示过去发生或完成的动作对现在造成的影响或结果,还表示过去发生动作一直持续到现在.其结构是have/has+及物动词的过去分词.
