31、e time has passed since+一般过去时”的句型中。Go 1.Two years has passed since he joined the League.BackIt is two years since he joined the League.2.He has been in the League for two years.He joined the League two years ago.二、一般现在时与现在进行时的转换 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.

32、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 will 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

33、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 play for ten minutes.A.has begun B.had begun C.has been on D.began 析

34、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。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”

35、。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 ma

36、ths 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。.中考实战题练兵中考实战题练兵A)A)用所给词的正确形式填空
