题目内容
19. he at home now?( )| A. | Is,playing | B. | Does,play | C. | Do,playing | D. | Is,plays |
分析 他现在正在家玩吗?
解答 答案:A.考查一般疑问句.句意"他现在正在家玩吗?".A现在进行时态.B一般现在时态.C不正确.D不正确.由now现在,可知应用现在进行时态,结构是is/am/are+动词的现在分词,主语是he第三人称单数,因此用be动词单数is,play的现在分词是playing,一般疑问句is提前.答案是A.
点评 一般疑问句变法,要考虑助动词、be动词、情态动词等的用法,还要考虑时态、人称、固定用法.根据语境完成试题.
