seandsimplepasttense.Thenexplainthedifferencesabout“howlong,howsoon,howoftenandhowfar”现在完成时:现在完成时表示从过去一直持续到现在的动作或状态，并可能还将持续下去。简称“延续用法”.此用法需注

意两点：1）常与for,since引导的时间状语连用.2）动词使用延续性动词。因为瞬间动词在肯定句、疑问句中不能和时间段连用.since,for的用法:since:(自…以来)1)since+时间点Hehasstayedheresince5o’clock.2)since+时间段+ago

Hehasstayedheresince5hoursago3)since+从句(句子要用一般过去时态）ShehastaughtEnglishsincehecamehere.for:（长达）for+时间段Hehaskeptthebookfor2weeks.2在现在完成时态中，for

与since引导的时间状语可以相互转换。since＋一段时间＋ago＝for＋时间段e.g.sincetwoweeksago=fortwoweeks;Ihavekeptthelibrarybookfora

week.=Ihavekeptthelibrarybooksinceaweekago.歌诀：含有for，since的现在完成时的用法歌诀:过去的动作或状态，一直持续到现在，for、since把时间带.用for和since填空。______threehours______th

sterdayafternoon______Icamehere______lastSunday在现在完成时中短暂性动词在肯定句、疑问句中不能与时间段连用。为了表述这种意思，我们常将短暂性动词转变成相应的延续性动词来代替非延续性动词，或变成：Itis+时间段+s
