9、e, begin, start, borrow, close, open, lend等。eg. I have bought this book for three months. ()非延续性动词与一段时间连用时可采用下列三种方法：（1）将非延续性动词转化为延续性动词。 leave- have (has) been away from close- be closed join- have (has) been (in) begin/start- be on buy- have (has) had go- be there die- have (has) dead finish- be ove

11、即：将时间状语改为过去时间，并用一般过去时代替现在完成时）如： 他参军五年了。（判断正误）He has joined the Army for five years. ( )He has been in the Army for five years. ( )He joined the Army five years ago. ( )他离开济南三年了。He has left Jinan for three years. ( )He has been away from Jinan for three years.He left Jinan three years ago.(3) 句子模式的变化

12、。用句型“It is + 一段时间+ since从句”（从句中的谓语动词用非延续性动词的一般过去式表示）如：The old man died two years ago.= The old man has been dead for two years.= It is two years since the old man died.5. have been to/ have gone to/ have been in 三种结构的区别（1）have been to 去过某地(现已离开)，可以与ever, never, once, twice等连用。（2）has gone to 去某地了，说话时

13、某人已离开此地，在去某地的路上或已在某地，总之现在还未回来。此句型一般用于第三人称。（3） have been in 表示已在某地呆了多久，若该地为小地方则用at。翻译： 你以前去过北京吗？_ 吉姆已经去了伦敦。_格林一家在中国已经两年了。_6. 现在完成时与一般过去时的区别：(1) 侧重点不同：现在完成时是与现在有关的时态，属现在时态范畴，它侧重于过去的动作对现在造成的影响。而一般过去时是一种过去时态，侧重于表示过去的动作，与现在无关。如： Yesterday I went to the zoo. (仅说明昨天去了动物园，与现在无关) Li Lei has read the book. (说

14、明李磊了解那本书的内容)（2）连用的时间状语不同：一般过去时常与ago, yesterday, last, in 2000, just now等连用。而现在完成时与already, yet, still, just, so far, in the last/ past, before, ever, never, since, for等时间状语连用。注 现在完成时不可与yesterday, last week, two days ago等过去时间状语连用。被动语态语态是动词的一种形式，它表示主语和谓语的关系。语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。 一、被动语态各时态构成表TENSE主动语态被动语态一般现在时beVVsamisare+ pp一般将来时wil
