题目内容

Jim         a skilled worker for almost six years. He is an experienced manager now.
A．has beenB．had beenC．isD．was
D

试题分析：句意为：Jim是一个技术工人近六年了，现在成了一个很有经验的经理。has done现在完成时，过去发生的动作一直持续到现在。由后面的现在是一个很有经验的经理可知不符合题意；had been 过去完成时，发生在过去的动作之前的动作，句中没有过去的动作或时间为参照，故不符合题意。一般现在时表示经常性，习惯性的动作，而是一个技术工人应在过去，现在是经理，由此可知现在时不符合题意。
