Question

1．那位四十多岁的男子已经坚持写作二十年了．
The manin his forties has kept writing for ten years．

Answer 1

分析 in his forties has kept．

解答 答案：in his forties has kept．结合句意可知开始写作发生在过去，一直持续了二十年，表动作的持续，故用现在完成时have/has+过去分词，主语是the man故has，坚持做某事keep doing sth，keep的过去分词kept，表示四十多岁，用介词短语in one's+基数词复数，作为后置定语修饰the man，in his forties四十多岁，故答案是in his forties has kept．

点评 in one's+基数词复数 表示在某人几十岁时．in one's+序数词 表示在某人多少岁时．注：基数词复数中基数词为整十的数！
