Unit3Onlinetours第3课时Grammar1.Newwordsandphrases:dream,passport,dreamabout/of2.Tounderstandthedifferencesbetweensimplepasttenseandpresentperfecttense.经典短语默写 重难句型过关 现在完成时与一般过去时区别现在完成时和一般过去时所表示的动作都发生在过去，但它们所强调的重点不同：现在完成时侧重于对现在的影响；而一般过去时侧重于某一动作发生在过去某个时间或某段时间，即现在完成时侧重于现在的结果，而一般过去时侧重于动作发生的时间。如：Isawthefilmthreedaysago.三天前我看了这部电影。（强调是三天前，而不是别的什么时候看的电影）MrGreenhasboughtanewputer.格林先生买了一台新电脑。（着重点是格林先生现在有了一台新电脑）现在完成时常与already，yet，just，ever，never，before等副词以及＂for+段时间＂，＂since+过去时间/从句＂等时间状语连用；而一般过去时则常与＂时间段+ago＂，justnow，yesterday，lastweek等表示过去的时间状语连用。如：Shehaslivedheresincetwoyearsago.她两年前就住在这里了。Shelivedheretwoyearsago.两年前她住在这里。易错考点注意：for和since的用法。①for+时间段译为：……时间②since+过去一个时间点(译为：自从……以来)③since+时间段+ago④since+从句(过去时)⑤Itis+时间段+since+从句(过去时)注意：瞬间动词(buy,die,join,lose...)与for或since引导的时间段连用时，要改变成延续性动词。变化如下：e/arrive/reach/getto→beingoout→beoutfinish→beoveropen→beopendie→bedeadbuy→haveFallill→beilleback→bebackPuton→beon/wearWorry→beworriedCatchacold→haveacoldsomeday和theotherday的区别someday指将来“总有一天、有朝一日、终将、(日后)某一天”，谓语动词用一般将来时。如:Yourwisheswilletruesomeday.总有一天你的愿望会实现的。Somedayyou’llhavetopayforwhatyouhavedone.总有一天你要为你的行为而付出代价的。theotherday相当于afewdaysago,意为“几天前、某天、那天、不久前”，句中用一般过去时。如：Imetherinthestreettheotherday.几天前我在街上碰见过她。Iboughtthewatchtheotherday.这手表我是几天前买的。一、单项选择1．Mr.Greenlikestravellingandhe________lotsofplacesofinterestallovertheworld.A．hasgoneto
