题目内容
8．The boys in Class 3 ________ a maths class at nine o'clock yesterday morning．（ ）| A． | is having | B． | was having | C． | were having |
分析 昨天上午九点三班的男生们在上数学课．
解答 答案：C．
根据时间状语at nine o'clock yesterday morning，判断设空处的动作在过去某个时刻正在进行着，且动作在一段时间内持续进行，所以用过去进行时，过去进行时的构成是：主语+was/were+动词的现在分词，主语the boys in Class 3"三班的男生们"是复数名词，所以be动词用were；故选C．
点评 本题考查了动词的时态．做题时，一定要特别关注有关的时间短语，这是判断句子时态的标志．在没有时间状语的情况下可以联系上下文根据语境来做出正确判断．
