题目内容
8.-I hear that Jason is planning to buy a car.-I know.By next month,he enough for a used one.( )
A. | will have saved | B. | will be saving | C. | has saved | D. | saves |
分析 ---我听说Jason正计划买一辆车.
--我知道.但是到下个月他才能攒够买一辆旧车的钱.
解答 答案:A
句中的时间状语By next month是"到下个月之前,不迟于下个月"的意思,所以本句要使用将来完成时:will+have+动词的过去分词形式,这里表示在将来即"下个月"之前完成"攒够买一辆旧车的钱"这件事.故选A
点评 做时态题时,找到时间状语很关键.如果句中的时间状语为"by+表示将来的时间"时,表示"不迟于将来某个时间,到将来某个时间为止";该句通常要使用将来完成时.
