题目解答
答案
A. has been writing; has written
解析
本题考查现在完成进行时和现在完成时的区分。解题关键在于：
- 时间状语：第一空的"these three years"强调动作从过去持续到现在，且可能继续延续，需用现在完成进行时；
- 动作结果：第二空强调"about forty articles"这一已完成的数量，需用现在完成时。
第一空分析
- 时间状语"these three years"表示动作从过去持续到现在，且可能继续延续；
- 现在完成进行时（has been writing）强调动作的持续性和重复性，符合语境。
第二空分析
- 数量短语"about forty articles"强调已完成的具体数量；
- 现在完成时（has written）表示动作在现在之前完成，且结果持续到当前。
