题目内容
10.-Are you watching TV,John?-No.I _____ my homework.( )
A. | do | B. | did | C. | am doing | D. | was doing |
分析 --John,你在看电视吗?
--不.我在做作业.
解答 答案:C
根据前面的疑问句"John,你在看电视吗?"和后面的否定回答"不"推断设空处的动作"做作业"正在进行着,所以用现在进行时.现在进行时的构成是:主语+am/is/are+动词的现在分词;主语是I,be动词用am,do的现在分词是doing.故答案为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.
