Tip1: circle the time.
Tip 3：区别现在完成时和一般过去式
探究二：区别现在完成时和一般过去时
现在完成时的持续型用法:现在完成时还可表示过去某一时间开始并一直持续到现在(包括“现在”在内)的动作或状态，该用法中的动词多是延续性动词，常见的时态标志词有since, fr等。注意：1. 对since和 fr引导的时间状语提问时, 常用hw lng。如：Jane has learned t play the pian since tw years ag.  (对划线部分提问) Hw lng has Jane learned t play the pian?2. 在现在完成时中，含有fr和since的句子可以相互转换。如 They have lived here fr five years. =They have lived here since five years ag.3. 在现在完成时中，表示短暂意义的动词(如cme和see)在肯定句和一般疑问句中不能和表示一段时间的时间状语连用，但在否定句中是可以的。如：Mike has cme t Lndn fr three weeks. (×)They haven’t seen each ther fr ages. (√)
Lu: I’ve arrived in the cinema.S : Hw lng have yu been in the cinema?Lu: I’ve been here fr 10 minutes.

start / begin
(2 hurs later)L: Where are yu? The mvie was ver. I have left.S: I’m n my way. Hw lng have yu been away?L: I have been away since the mvie was ver.
be away (frm)
短暂性(短语)动词与延续性(短语)动词和与表示状态的短语之间的转化1. 有些短暂性(短语)动词可转化为相应的延续性(短语)动词。常见的有： becme → be （成为） brrw → keep （保管） buy → have / wn （购买 ) catch a cld → have a cld （感冒） cme → stay  （来，停留） put n → wear（穿着） g t sleep → sleep  （睡觉） mve t → live in（搬到）
2. 有些短暂性(短语)动词可转化为表示状态的短语。常见的有： leave → be away    （离开） begin / start → be n（开始） die → be dead （死亡）   finish → be ver（结束） jin → be in / be a member f（加入） fall asleep → be asleep    （睡觉） marry → be married  （结婚） cme / arrive here → be here（来到，到达这儿）
巧记瞬间性动词的转换:开始离去借来还， 出生入死买到家， 穿衣入睡要感冒， 开开关关变结束。
