题目内容
10.Sam ______ football with his friends on the playground now.( )| A. | plays | B. | played | C. | will play | D. | is playing |
分析 山姆和他的朋友们现在正在操场踢足球.
解答 答案:D 根据时间状语now,可知"踢足球"这一动作正在进行,所以考虑用现在进行时态,结构为 am/is/are+doing,由于主语是山姆,是单数第三人称,所以be动词用is,故选D
点评 本题主要考查现在进行时态的运用,结构为be+doing.只要找到关键的时间状语,就能够准确判断时态.
