2.表示一个从过去开始，一直持续到现在的动作或状态。通常和for或since引导的时间状语连用。注意：动词延续性（1）for

+ Ihavebeenherefor5weeks. He’sstudiedEnglishfor3years. Shehasworkedfor10hours.一段时间（2）since

+

(过去的)时间点Ihavebeenheresince2000.Hehasworkedasalawyersince5yearsago?They’velivedinCQsincetheymarriedin2000.

注1)：since也可单独使用,表示“自那时起”；另外since前也可加上ever，以加强语气。 Ihavebeenhere(ever)sincethen.

注2)：对for或since引导的时间状语提问用howlong Ihavelivedherefor10years.Howlonghaveyoulivedhere?Shehasstoodheresince2hourago.Howlonghasshestoodhere?注3)：短暂性动词不能和for或since引导的时间状语连用，也不能用于howlong问句中。

（误）Ihaveleftfor5years.(正)Ihavebeenawayfor5years.※短暂性动词与延续动词间的转换短暂性(短动词)动词不能和表示一段时间的时间状语连用,但是他可以转换成相应的延续性(长动词)动词.leave--come/go(to)--arrive(at/in)--get(to)--reach--buy--borrow--finish--join--start/begin--die--close--open--return--marry--become--
