--- What were your parents doing at eight last night?--- My father was cooking while my mother . A．watched TV B．were watching TV C．is watching TV D．was watching TV

Answer 1

D

试题分析：句意：昨晚八点你的父母正在做什么？——我父亲一边做饭，我母亲一边看电视。结合语境可知下文描述的是过去某时正在进行的动作，while引导时间状语从句强调主从动作的同时发生，my mother为单数第三人称，故助动词用was，选D。 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。
