现在完成时态中终止性动词与延续性动词

现在完成时态中终止性动词与延续性动词
英语中的动词根据词汇意义可分为动作动词和 状态动词，其中动作动词又可细分为终止性动词（或称为瞬间动词、非延续性动词、
非持续性动词、界限 性动词）和持续性动词（或称为延续性动词）；表示动作一发生即告结束的动词叫终止性动词，表示持续一段时间的动词叫持续性动词。这种依据动作是否可以延续的分类在英语中是一种极其重要而又非常有价值的，使 用时一定要格外小
心，不然就会犯错误。

一、现在完成时态的结构是havehas ＋Ｖ 动词过去分词．英语中常见的终止性动词有：leave， go，come，arrive，begin，
buy，borrow，die，join， beco me，marry，graduate，become等。由于终止性动词所表示的动作发生与结束在一瞬间完成 ，所
以终止性动词的完成体的肯定式既不能与表示一段时间的状语for ＋时间段或 since ＋时间点连用，也不能用在how long引导的
特殊疑问句之中。例句：

我哥哥参军两年了。My brother has joined the army for two years．（误）
我哥哥自1999年就参军了。My brother has joined the army since 1999．（误）
你哥哥参军多久了？How long has your brother joined the army ？（误）
如用持续性动词表示瞬间的行为，则必须借助come（表示动作的渐进过程），begin， get（表示动作的变化过程）等动词。
例句：
I studied English thirteen years ago．（误）
I began to study English thirteen years ago．（正）
When did you know him？（误）
When did you get to know him ？（正）
二、终止性动词肯定形式可使用完成体，但其肯定形式的完成体不能与一段时间状语连用。可用以下三种 方法替换：
⑴时态替换法
将时间状语改为“时间段＋ago”，句中谓语动词用一般过去时。例句：
My brother joined the army two years ago．
The old man died ten years ago．
He left his hometown thirty years ago．
⑵句型替换法
①用It is（或has been）＋时间段＋ since…句型改写，该句型中since后面的谓语动词多为点动词，且常用一般过去时。
例句：
It is（或has been）two years since my brother joined the army．
It is ten years since the old man died．
It is（或has been）thirty years since he left his hometown．
注：Itis／hasbeen．．．since．． ．句型中的动词若为持续性动词，计时的起点是since句中动词结束之点。不然应将since
句中 的动词改为begin to do sth．。例句：
It's five years since he studied English．他不学英语已五年了。
It's five years since he began to study English．他学英语已五年了。

②用一段时间＋has ／have passed since S＋V-ed句型改写。例句：
Two years has ／have passed since my brother joined the army．
Thirty years has ／have passed since he left his hometown．
⑶动词替换法
若保留for ＋时间段，since ＋时间点或用在how long句型中，需将终止性动词改为相应的持续性动词或状态动词。例句：
My brother has been in the army for two years．
Jack has been a postman for about six years．
When he came home，I had been asleep for three hours．
Of course I know him very well because we have been friends for ages．
—How long have you been here？
—About two months．
三、常见终止性动词与持续性动词（或状态动词）的对应关系如下：
leave→be away（from） 离开borrow→keep借finish ／end ／stop→be over 结束完成
join the army→be ／serve in the army ／be a soldier入伍参军
join the Party→be in the Party ／be a Party member 入党（入团入WTO等）
catch ／get a cold→have a cold感冒fall asleep→be asleep 睡着
go to school→be in school／be a student上学go abroad--- be abroad去国外
begin→be on 开始put on（上演）→be on 上演buy→have 买become→be 成为marry→be married（to）结婚
wake up→be awake 醒make friends with→be friends with成为交朋友lose→be lost ／be missing ／be gone
丢失lose one's job ／work→be out of work ／a job openciose die →be opencloseddead 开办关闭死
短暂性动词变延续性动词(一定变为对应的过去分词规则+ed ,不规则看过去分词表)：写出括号中的中文意思:
1).has have joined --- has have been (a member ) in+ 组织(加入)
2) has have comegone got arrived --- has have been to ( )
has have begun --- has have been on ( )
3) has have borrowed --- has have kept ( )
4) has have bought --- has have had ( )
5) has have left --- has have been away from ( )
6) has have opened closeddied ---has have been open closeddead()
