题目内容
19.Look!The boys _______ football on the playground.( )A. | plays | B. | play | C. | are playing | D. | played |
分析 句意:看!男孩子们正在操场上踢足球.
解答 答案:C.根据关键词look可知,后面是正在进行或发生的动作,所以是现在进行时态,look是现在进行时态的标志词,现在进行时态的构成:be+动词的现在分词,主语the boys是复数形式,所以系动词用are,动词用ing形式;故选C.
点评 解决此类题目的关键是要掌握不同时态的构成、表示的含义和标志词,如:look、listen和now是现在进行时态的标志词,达到能在不同的语言环境中熟练运用不同的时态.
