题目内容
8．-How happy the grandparents are!-Yes，they for fifty years．（ ）
| A． | have been married | B． | have married | ||
| C． | have got married | D． | married |
分析 -祖父母多么高兴啊!
-是的，他们已经结婚五十年了．
解答 答案：A 根据for fifty years可知，这是一个表示一段时间的时间状语，而get married是瞬间性动词，不能持续一段时间，所以要用be married，它后面可以跟表示一段时间的状语；要用现在完成时，现在完成时态的结构为have/has+动词的过去分词，主语是they，所以助动词用have，故选D．
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．此题注意短暂性动词和延续性动词区别．
