题目内容

9．Keep quiet，please．Someone _______to a concert inside now．（　　）

A．

is listening

B．

has listened

C．

was listening

D．

listened

分析请安静，现在有人在里面听音乐会．

解答答案A 根据句中Keep quiet及时间状语now可知，此句描述现在正在发生的事情，故用现在进行时态，现在进行时态的结构为is/am/are+动词的现在分词；又知主语为someone不定代词，搭配is．故选A

点评判断时态，不仅可以根据明显的时间状语，也可根据上下文情景
