题目内容
3.-Did you see the film last night?-No,I ______ some shopping at that time.( )
| A. | am doing | B. | was doing | C. | did | D. | will do |
分析 你昨晚看电影了吗?--没有,那时我正在购物.
解答 答案:B.根据关键词at that time可知,本句是过去进行时态,表示在那时正在做某事;其构成为:was/were+v-ing,主语I是第一人称,系动词用was,do的现在分词为doing,故选B.
点评 本题考查动词的时态,解决此类问题的关键是根据标志词和时间状语来确定动词的形式,在不同的语言环境中达到熟练掌握的目的.
