探究一. present perfect tense with since & fr
It has been here fr five years. It has been arund since 1993.It has been arund since 28 years ag. We have been here since we gt married.
现在完成时表示从过去开始一直持续到现在还有可能继续持续下去的动作或状态。常与_________引导的时间短语或从句连用.
fr + ________ 表示“持续了...
【拓展延伸】含 fr 和含 since 的现在完成时的句子有时可互相转换。我从13年前开始就住在这里。I’ve lived here since 13 years ag.= I’ve lived here fr 13 years.= It has been 13 years since I began t live here.

My friends haven’t visited me ___________ my birthday. 11.She hasn’t had a gd cup f cffee _______years. 12. Tm has wrn glasses _________ tw years ag.
探究二. 延续性动词与非延续性动词
思考: 与hw lng, fr 或者since搭配使用在现在完成时中的动词有什么共同特点？
Hw lng has Mary left? Hw lng has Mary been away?B. Hw lng has he brrwed the bk? Hw lng has he kept the bk?C. Maria has cme back since Mnday. Maria has been back since Mnday.D. Tny has bught the cmputer fr tw years. Tny has had the cmputer fr tw years.
英语中，按动词延续的时间长短，可将动词分为____________和_____________。延续性动词，如：learn “学习”，wrk“工作”，play“玩耍”等。短暂性动词，即动作一开始便结束的动词，如：cme“来”，g“去”，begin“幵始”，becme“变成”，buy“购买”。延续性动词，就是可以想做多久就做多久的事情，只要你不累。短暂性动词就是一瞬间的事情。当句子中出现“fr+一段时间”，“since+从句”，“since+表示时间点的名词”，hw lng等，这些时间状语的时候，不能使用短暂性动词，要使用延续性动词。用于现在完成时。
（口诀记忆：看见since，fr，hw lng；廷续性动词不能忘）

Can they last?
start/begin
catch/get+病

2. I brrwed the bk five days ag.(一般过去时)
brrw借(短暂) →keep保存(延续)
