过去进行时用法一得
 
有这样一道题：
I don’t think Jim saw me; he __________ into space. www.34en.com
A. just stared                                       B. was just staring 
C. has just stared                                 D. had just stared
【分析】此题应选B。主要考查动词过去进行时的基本用法(即动作在过去某一时刻正在进行)。此题的上文设置比较巧妙：前面的主句用了I don’t think(指现在的看法)，而其后的宾语从句用的是saw(指过去的动作)，也就是说此题的语境是：现在谈论过去的情况，全句意为：我认为吉姆当时没看见我，(因为)他当时正在朝天空看。
