1、No, 主语+ havent / hasnt.（否定） 第二部分:现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义:以already, just和yet为标志 already, just和yet表示到现在为止动作或状态已经、刚刚或还没有发生。He has already got her help.他已得到她的帮助。He has just seen the film.他刚刚看过这场电影。He hasnt come back yet.他还没有回来。以ever和never为标志 ever和never表示到现在为止动作或状态曾经或从来没有发生过。This is th

2、e best film I have ever seen.这是我曾经看过的最好的一部电影。He has never been to Beijing.他从没有到过北京。以动作发生的次数为标志 若某一动作到现在为止已经发生了若干次,则要使用现在完成时。He says he has been to the USA three times. 他说他已经去过美国三次了。以so far为标志 so far往往表示到目前为止动作或状态已经发生。He has got to Beijing so far.到目前为止他已到了北京。She has passed the exam so far.到目前为止她已经通过了
