题目内容
Most people _______when the big earthquake took place in that area.
| A．are sleeping | B．were sleeping |
| C．slept | D．sleep |
B
解析试题分析：当地震发生时，在那个地区大部分人正在睡觉。结合语境可知本句描述的是过去某时正在进行的动作，故用过去完成时态，选B。
考点：时态
点评：英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型，首先要注意句子中的时间状语，如果没有则要通过分析上下文，结合语境来判断句子的时态。英语疑问句中一般具有时态上的对应关系，注意结合这一特点进行区分。
