选择题
Jim ______ a late night film at home when, right in the middle a thrilling scene, the television went blank.
A.watched
B.had watched
C.was watching
D.would be watching
答案
答案:C
be doing...when...表示“正在做某事……突然……”。根据题意可知“吉姆正在看午夜电影时电视突然显示空白”,由下文的went可知是过去正在做某事所以用was watching。句意:吉姆正在家看午夜电影时,正好就在一个惊险场面的中途,电视突然一片空白。
