already,yet,ever,never,just,since,for。现在完成时态Simplepasttenseandpresentperfecttense一般过去时和现在完成时都可以表示过去发生的动作，刚刚接触现在完成时的时候，很多同学会把它与一般过去时相混淆，这里就说一说它们的区别。一、构成不同Theylivedherein2011.他们2011年住在这里。Wehavelivedhereforthreeyears.我们已经在这里住了3年了。一般过去时：主语+谓语动词的过去式现在完成时：have／has+动词的过去分词

HevisitedGuilinin1998.他1998年参观过桂林。ShealwaysswamintheseawhenshelivedinQingdao.她住在青岛的时候，总是去海里游泳。Jill

computer.

吉尔买了一台新电脑。Ihavehadmylunch.我已经吃了午餐。二、用法不同一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作。说话的侧重点只在于陈述一件过去的事情，不强调对“现在”产生的影响。现在完成时表示的动作或状态与现在的情况有联系，侧重这一动作对现在所造成的影响。Hehasreadthatbook.(说明他现在知道那本书的内容。)Hereadthatbooklastyear.(只说明他去年读过那本书。)HehasgonetoAmerica.(他现在不在此地，到美国去了。)HewenttoAmerica.(只说明他去过美国。)三、时间状语不同Didyouwatchthatfilmlastweek?你上周看那部电影了吗？Shecamebackyesterday.她是昨天回来的。Hisfatherhasbeenateachersince1968.他父亲从1968年以来一直当老师。—Haveyouever

beentoLondon?—No,Ihavenever

beenthere.—你曾经去过伦敦吗？—没有，以前从没去过。一般过去时通常与表示过去的具体的时间状语连用。如：yesterday,lastweek,twoyearsago,justnow,in2002等；而现在完成时则常与表示不确切的时间副词连用，如already,yet,ever,never,just,since,for。I________(visit)thePalaceMuseumwithmygrandparentstheotherday.I________(climb)MountHuanglastsummer.visitedclimbedCompletethesentenceswiththecorrectformsofthewordsinbrackets.onpape41IamhappythatI___________(learn)toswim.______youever______(try)thefamousTianjinBaozi?Havetriedhavelearntdream(dreaned/dreamt)dreamof/about
