题目内容
14．Jack ___ great changes in Beijing since he came here．（ ）| A． | sees | B． | will see | C． | has seen | D． | saw |
分析 自从Jack来到这里，他看到北京发生了很大的变化．
解答 答案：C．
根据since he came here可知，"自从他来到这里"在这里表示一段时间，表示过去的动作一直持续到现在，应该用现在完成时态；现在完成时态的结构为have/has+动词的过去分词，主语是Jack，所以助动词用has，故选C．
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．
