1、现在完成时态是中考的必考时态，由于现在完成时态既涉及到过去，又联系到现在，和一般过去时态，一般现在时态，现在进行时态既有联系，又有区别，所以同学们掌握起来比较困难。现把这种时态的用法简单的总结一下，和各位老师共同切磋。1.现在完成时态表示过去发生的动作对现在造成的影响或结果Ourteacherhasleft.WehavestudiedEnglish.Ihavealreadyfinishedthehomework.Hehashadhislunch.Hehasbecomeadoctor.我们老师已经离开了.Ourteache

2、rhasbeenaway.(F)Ourteacherhasleft.(T)错误的认识:(1)必须使用延续性动词.(2)延续性动词必须和一段时间连用.构成have/has+过去分词2.某个动作从过去已经开始,一直持续到现在,还有可能持续到将来.动作的持续性要通过一段时间来表示.一段时间的表达方法有两种:for:+一段时间forayearfortwoweeksforthreeyearsSince过去的某一时刻,sinceninesincelastweek一般过去时态的时间状语从句sinceyoucamesinceyougot

3、home.注意:for和since所引导的时间状语都表示一段时间.Hehasbeenawaysincelastweek.Hehasbeenawaysincelastweek.对划线部分提问都用Howlong结束性动词不能和表示一段时间的时间状语连用,但是他可以转换成相应的延续性动词.1.直接用延续性动词buy–havecatch(get)acold–haveacoldborrow—keepCome/go/become—beputon--wear2.转换成be+名词jointhearmy–beasoldierJointhe

4、Party–beaPartymembergotoschool–beastudent3转换成be+形容词或副词die—bedeadfinish–beoverbegin—beonleave—beawayfallsleep–beasleepclose–beclosed4.转换成be+介词短语gotoschool–beinschooljointhearmy–beinthearmy1.我们买这本书三年了.Wehavehadthebookforthreeyears.2.他感冒三天了.Hehashadacoldforthreedays

5、.Weboughtthebookthreeyearsago.Hecaughtacoldthreedaysago.一般过去时态和现在完成时态可以构成同意句3.自从上星期我借的这本书Ihavekeptthebooksincelastweek.4.我成为一个学生两年多了.Ihavebeenastudentforovertwoyears.Iborrowedthebooklastweek.Ibecameastudenttwoyearsago.5.MrBlack死了三年了。MrBlackhasbeendeadforthreeyear
