题目内容
2.I often heard her in the room..( )| A. | sing | B. | sang | C. | singing | D. | sings |
分析 我经常听到她在房间里唱歌.
解答 答案:A.根据I often heard her in the room,可知本句考查了hear的用法:hear sb doing sth,听到某人正在做某事,hear sb do 听到某人做某事.再根据often,表示在一个时间段内的常规行为,而非每秒每刻都正在进行的行为,所以用动词原形sing.故选A.
点评 本题考查了非谓语动词的用法.解答时注意:hear sb doing sth,听到某人正在做某事,hear sb do 听到某人做某事.
