28、,在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作),at school(上学、上课)等。此短语可与进行时态转换。,e.g.Peter is at work,but Mike is at play.=Peter is working,but Mike is playing.,三、现在进行时与一般将来时的转换,在现在进行时态中go,come,leave,start,arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如:I am coming,Mum!意为“我就来,妈妈!”,e.g.The train is leaving soon.=The train w

29、ill leave soon.,四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换,“be going to+动词原形”、表示打算、计划要做的事;将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall。在口语中,所有人称都可以用will。,e.g.We are going to visit the Great Wall next Sunday.=We shall visit the Great Wall next Sunday.,.中考动词时态考点分析,一、根据时间状语确定时态的原则,1.Hurry up!The

30、 play for ten minutes.A.has begun B.had begun C.has been on D.began,析 1.C。since后接时间的起点,for后接时间段,主句动词用现在完成时,应注意瞬间动词与延续性动词的使用。,二、在复合句根据时态呼应确定时态的原则,2.Do you know if back next week?If he back,please let me know.A.he comes;will come B.will he come;comes C.he will come;comes D.will he come;will come,析 2.C

31、。if既可引导宾语从句,也可引导状语从句。充当宾语从句的连接词时,相当于whether,词义是“是否”。充当状语从句的连接词时,词义是“如果”。从时态看,if引导宾语从句时谓语动词的时态应根据主句的时态作相应的变化;引导表示将来动作或状态的条件句时,若主句用一般将来时,则从句通常用一般现在时表示将来。,三、根据上下文已有时态信息点确定时态的原则,3.When this kind of computer?-Last year.A.did;use B.was;used C.is;used D.are;used,析 3.B。此例由下句的时间状语推断出一般过去时态,并且要考虑到被动语态。,四、利用上下

32、文语意确定时态的原则,4.Hi!Lin Tao.I didnt see you at the party.-Oh,I ready for the maths exam.A.am getting B.was getting C.got D.have got,析 4.B。此例由didnt,at the party推断出应用过去进行时。,五、时态中的“特殊”对策的原则,5.The teacher told us yesterday that December 25 Christmas Day.A.is B.was C.has been D.will be,Go,析 5.A。有些动词其动词的时态是“违

33、背常理”的。如宾语从句表示的是一个客观事实或客观真理时,其时态不受主句限制而用一般现在时表示。,.中考实战题练兵,A)用所给词的正确形式填空:1.Mr Brown will go fishing if it(not rain)tomorrow.2.I think he(be)back in a week3.Who(knock)at the door?-I dont know.Let me go and see.4.Bill is strict with himself.He never(leave)todays work for tomorrow.5.-your uncle(return)th

34、e video tapes to Mr Fox?-No.Theyre still in his bedroom.,doesnt rain,will be,is knocking,leaves,Has,returned,6.By the end of last term,they(work)there for ten years.7.Mr.Wang(read)a newspaper in the office at this time yesterday.8.Mr.Green and his wife(live)in London for a few years before they(come

35、)to work in China in 2001.9.They never knew what(happen)to the world in a hundred years.10.About 400 years ago,Galileo(伽利略)proved that the earth(go)around the sun.,had worked,was reading,had lived,came,would happen,goes,Go,B)根据汉语意思,完成下列句子:When I got to the cinema,(电影已 经开始了).2.(有一场音乐会)a concert tomorrow afternoon.3.Its three years since he(入团).4.Please let me know(他一回来).5.I(正要入睡)when there was a loud knock at the door.,the film had already been on,There is going to be/will be,joined the League,as soon as he comes back,was just falling asleep,Thats all for today.,Goodbye!,
