Grammar 现在完成时态(三) for 和since 的用法 考点 1 现在完成时的“未完成”用法表示动作或状态从过去某时开始，一直延续至今，还可能继续下去。since和for 是现在完成时当中常见的标志词。since “自从……”，for“持续了……”。since 用来说明动作的开始时间，for 用来说明动作延续的时间长度。 Grammar since + 过去的时间点 eg: I have been very sad since the last time. 从上次开始，我一直很伤心。 for + 时间段 eg: Tina has been away from home for five years. 蒂娜离开家已经5 年了。 Grammar Betty _____ hard since last term.

I _____ it for less than one month. A. bought B. have bought C. had D. have had D Let's Do It 延续性动词与非延续性动词 考点 2 若现在完成时的句子中含表示时间段的时间状语(如含since/for引导的时间状语)，则谓语只能使用延续性动词。 延续性动词表示能够延续的动作。短暂性动词 表示不能延续的动作，这种动作发生后立即结束。 【难点】 【易错点】 Grammar 短暂性动词可以转化为延续性动词 1. 直接换成延续性动词　 buy买→have有　 borrow借→keep保留　 put on穿上→wear穿着 come/go/become来/去/变成→be在/是 Grammar 2. 转换成be＋名词 join the army参军→be a soldier当兵 join the Party 入党→be a Party member成为一名党员 go to school去上学→be a student成为一名学生 3. 转换成be＋形容词/副词 die死亡→be dead死了 finish结束→be over结束 Grammar begin开始→be on 在上映/已开始 leave离开→be away远离的 fall asleep入睡→be asleep睡着的 close关闭→be closed关着的 4. 转换成be＋介词短语 go to school去上学→be in school在上学 join the army参军→be in the army在军队中 Grammar —I’m sorry for being late. — Never mind.
