现在完成时被动语态练习.doc

现在完成时（The present perfect tense）的用法小结
一、现在完成时的结构：_______________________________________________
现在完成时的被动语态结构：_________________________________________
现在完成时的进行时态：_____________________________________________
二、用法：现在完成时既涉及_______，又联系__________。
用法一：表示过去发生或已经完成的某一动作对现在造成的影响或结果。常与just（刚刚），already（已经），never（从来没有），ever（曾经），before（以前），yet（仍然），once（一次），twice（两次），many times（很多次），how many times（多少次），so far（迄今为止），during the past（last）three years（最近三年来）等连用。
用法二：表示过去已经开始，一直延续到现在的动作或状态。时间状语有：
①    for＋表示一段时间的词语I have taught English for 19 years。
②    since＋表示过去时间点的词语He has been at this school since 1986.
③    since＋表示过去的时间状语从句I have lived here since I was born.
④    since＋一段时间＋ago. I have known him since 20 years ago.
三、现在完成时态中可以和表示一段时间状语（for，since，how long, all one’s life）连用的动词必须是表示延续的情况或动作的动词，即延续性动词。如：be，have，know，live，work，study，learn，teach，keep，speak，talk，draw，wait，wear，walk，sleep，drive，write，do，clean等。
I ____________________________for nearly 20 years. 我当老师已经有20年了。
How long _________________________here? 他住在这多久了？
四、延续性动词的现在完成时可和包括“现在”在内的（到说话时仍未结束）表示一段时间的状语连用。如this morning，today，this week，these days
He has been to Beijing three times this year.
五、英语中还有一些动词的意义决定它们所表示的动作不能延续,只是一瞬间就结束的动作,这类动词叫做“非延续性动词”，常见的有：come，go，arrive，reach，see，hear，close，open，leave，begin，start，lose，buy，fall，join，die，get up，become，borrow，lend，find，finish，receive等。这些动词可用于现在完成时，说明某个动作的结果还存在，但不能和表示一段时间的状语（how long，for，since）连用。
判断正误：
He has come back.（ ）
He has come back for two hours.（ ）
六、如何通过与一般过去时做比较,进一步掌握现在完成时?
一般过去时和现在完成时的动作都发生在过去,但意义却不同.

（1） 一般过去时只表示过去的动作或状态,和现在不发生关系。
现在完成时表示过去发生的某一动作对现在造成的影响,强调的是现在。
如:I learned ten English songs（说明过去学过,现在是否记得,不是本句的内容）
I have learnt ten English songs.（learn发生在过去,但强调我现在懂英语歌曲）
I cleaned the blackboard half an hour ago.（只说明“擦”和其发生的时间）
I have cleaned the blackboard.（说明现在黑板是干净的）
The teacher has written some new words on the blackboard（黑板上现在有单词）
The teacher wrote some new words on the blackboard（黑板上现在没有单词）
（2）一般过去时可以和表示过去的时间状语连用,如:yesterday, last year, three days ago, just now, 等。现在完成时不能和表示过去的时间状语连用,其时间状语可以是since…,for… , just, ever, never, before, already, yet , so far, all one’s life等
