Question

Jim ________ a late night film at home when，right in the middle of a thrilling scene，the  television went blank.                                         (2013·陕西，17)

A．watched	B．had watched
C．was watching	D．would be watching

Answer 1

C

句意为：吉姆在家看一部午夜电影，看到中间一幕惊险的场景时，屏幕上突然出现一片空白。该句考查be doing...when...结构，意为“正在做……就在这时(突然)……”。从后面的动作went blank可知“看电影”发生在过去；并且是当吉姆正在看的时候，所以该题要用过去进行时态，即was watching。
