现在完成进行时和现在完成时都可以表示“从过去开始一直持续到现在”这一概念,有时两者可以互相代用,但前者多用于口语。在含义上如着重表示动作的结果时,多用现在完成时;如着重表示动作一直在进行,即动作的延续性时,则多用现在完成进行时。一般不能用于进行时的动词也不能用于现在完成进行时。要求1.背不规则动词表，默写2.记住现在完成时常用的时间状语与副词3.练习beento三个易混的结构havebeento去过havegoneto到……去了havebeenin去了/来了/到了+一段时间1.IhavebeentoGuangzhou.2.Ihave_________Guangzhoumanytimes.3.Hehas__________Harbin.4.Myfatherisn’tathome.Hehasgoneto

IV.有些动词属于”结束性动词”(或叫瞬间动词)即动作不能持续,一发生即结束,因此不能接一段时间.如以下词:go/come/arrive/getto/join/leave/die/begin/buy在接一段时间时,就要用另外的词来代替:1.havejoined---havebeen(in)/a…HehasjoinedtheParty.他已入党了.Hehas_______thePartyfortenyears.他已入党十年了.HehasbeenaPartymemberfortenyears.2.haveleft---havebeenawayShehasleftZhuhai.她已经离开珠海.Shehas__________Zhuhaiforhalfaday.
