— Why do you do volunteer work in the North-West?
— I_______ to improve the lives of the children there through my efforts.

A.was trying B.have tried C.am trying D.tried

C

解析试题分析:考查时态。句意:--你为什么选择去西北地区做志愿服务?--通过我的努力,我正在努力改善那里孩子们的生活。过去进行时用来指过去的某个时刻正在发生的事情,根据第一句中的Why do you...可知,这里不用过去的时态,排除A、D;现在完成时表示发生在过去的事情对现在造成的结果,参加志愿服务这件事并未结束,因此不用现在完成时,故选C。
考点:考查时态
