题目内容
20.-Please turn off the radio,grandma ___now.-OK,I'll do it right now.( )
| A. | is sleeping | B. | will sleep | C. | slept | D. | sleeps |
分析 -请关掉收音机,奶奶在睡觉.
-好吧,我马上去做.
解答 答案:A 根据表示时间状语的副词now可知,此句表示动作正在进行,所以用现在进行时态;现在进行时态结构形式为助动词be+v.ing;又因为主语grandma是可数名词单数形式,助动词用is.故选A.
点评 判断动词的时态,要通过所给的时间状语、提示词或语境去判断动词存在的状态.注意主语和谓语动词的单复数要保持一致.
