(完整)现在完成时延续性与暂短性动词用法
现在完成时(短暂性动词与延续性动词)的用法基本结构：主语+have/has+过去分词（done）①肯定句：主语+have/has+过去分词+其他②否定句:主语+have/has+not+过去分词+其他③一般疑问句：Have/Has+主语+过去分词+其他④特殊疑问句：特殊疑问词+一般疑问句(have/has+主语+过去分词+其他）(1）现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系，也就是说,动作或状态发生在过去但它的影响现在还存在.I have spent all of my money.（含义是：现在我没有钱花了.)Jane has laid the table.（含义是:现在桌子已经摆好了.)Michael has been ill。

（含义是：现在已在此地）(2）现在完成时可以用来表示发生在过去某一时刻的，持续到现在的动作(用行为动词表示）或状态（be动词表示）常与for（+时间段），since（+时间点或过去时的句子）连用。
Mary has been ill for three days.I have lived here since 1998。
注（超重要）:瞬间动词（buy，die，join，lose……）不能直接与for since 连用.要改变动词come-be go out—be out finish-be over open—be opendie-be dead1。
have代替buyMy brother has had(不能用has bought) this bike for almost four years。
2、用keep或have代替borrowI have kept（不能用have borrowed) the book for quite a few days。
延续性动词和短暂性动词和现在完成时题目
He joined the Party 2 years ago.He has bee n in the Party for 2 years. I bought the book 5 days ago.子中的谓语动词一般为延续性动词。
但是，有些动词所表示的动作是短暂的，这类动词 叫做非延续性动词。
如： come, go, reach, arrive, leave, borrow, buy, jo in, die, begi n, start, finish 等。
在现在完成时的句子中，非延续性动词作谓语动词时，不能和表示一段时间的 状语连用。
表示动作的连续性，就要把非延续性动词转换成相应的延续性动词或短语，具 体转换如下：（要求记住）come/go/reach/arrivein/be leave 宀 beaway from, borrow keep, buy have, jo inbein/be a member of, die bedead, start/begin rbe finish/endbeer, openbe open (adj.), close be closed (adj.), marry Ice m eatci6/(go back to / returnto beback to go out be outbecome be get upbe dpi be dead fall asleep /get tot sleep be asleepienot have put on wear catch / get a coldhave acold ； get to know knovhave / has gone tohave been in注意：1. 非延续性动词可以在现在完成时的否定句中作谓语，并可以与 for , since 引导的时间状语连用，表示动作的延续过程。
例如：She hasn ' t bought anyew clothes since last year.2. 在现在完成时的肯定句中，非延续性动词作谓语时不能与 for , si nee 引导的表示一段时间的状语连用，但可以用其他句式来表示同一个意思。
修改名词：现在完成时练习(短暂性动词与延续性动词的转换)
修改名词：现在完成时练习（短暂性动词与延续性动词的转换）现在完成时是英语语法中一种重要的时态，用于表示发生在过去但与现在有关的动作或经验。
在构成现在完成时的句子中，我们经常需要使用动词的现在分词形式。
然而，对于一些动词，我们需要将其转换为名词形式。
短暂性动词的转换短暂性动词是指表示短暂或瞬间动作的动词，这些动作不具有持续性。
在现在完成时句子中，我们需要将短暂性动词转换为名词形式。
举个例子：- 原始句子：He drank a cup of coffee.- 转换后的句子：He has had a cup of coffee.在这个例子中，我们将短暂性动词"drank"转换为名词形式"had"。
以下是一些常见的短暂性动词及其对应的转换形式：- bring -> have brought- eat -> have eaten- see -> have seen- take -> have taken- buy -> have bought延续性动词的转换延续性动词是指表示持续性或进行性动作的动词，这些动作具有一定的时间跨度。
在现在完成时句子中，我们需要将延续性动词转换为名词形式。
举个例子：- 原始句子：She has been reading a book.- 转换后的句子：She has had a book.在这个例子中，我们将延续性动词"reading"转换为名词形式"had"。
以下是一些常见的延续性动词及其对应的转换形式：- read -> have had- write -> have written- study -> have studied- work -> have worked- play -> have played通过将短暂性动词和延续性动词转换为名词形式，我们可以更准确地表达现在完成时的动作或经验。
现在完成时中短暂性动词变延续性动词归纳表

1. 完成时态的肯定句 2. 句中，有for或since引导的，或其他种类的表示一段时间的时间状语

现在完成时短暂性动词
短暂性动词，延续性动词和现在完成时短暂性动词是指动作一旦发生就立即结束。
它不能和一段时间连用。
这类动词有：go, come, arrive, leave, begin, start, join, marry等；短暂性动词的肯定式不能与表示一段时间的for或since或how long等状语连用。
例如：His father got ill. I have received his letter.但是，不可以说：His father got ill for a week.I have received his letter for three days.在否定句中，短暂性动词可以和表示一段时间的状语连用。
例如：We haven’t heard from Jane for a long time.I suppose something must have happened to her.延续性动词是指动作发生后还可以延续一段时间或者相当长的一段时间。
如：live, work, study, learn, sleep等，延续性动词可以和表示一段的时间状语连用。
值得注意的是，表示一段时间的状语除了“for+一段时间”外，还有since+n./从句（时间点），since+时间段+ago，疑问词how long，in the past+时间段，all these+时间段，from…to（时间点）以及till/until+n./句子等等。
例如：How long _______ your brother joined the army?A. hasB. hadC. is it sinceD. was there that通过审题，答案B和D很容易被排除，但是稍不注意便会选中答案A；殊不知how long为一段时间的状语，不能与非延续性动词短语has joined连用，所以这题的正确答案是C。
另外，动词的延续性与非延续性还体现在这两种句型中：延续性动词的肯定式+till/ until 短暂性动词的否定式+till/ until请看例句：We waited until he came.I didn’t go to bed until my father came back home last night.如果短暂性动词与表示一段时间的时间状语连用，必须将短暂性动词改为延续性动词。

短暂性动词与延续性动词的用法
短暂性动词与延续性动词在现在完成时中的用法英语中的动词有多种分类法。
根据其有无含义，动词可分为实义动词和助动词；根据动词所表示的是动作还是状态，可以分为行为动词和状态动词；根据动词所表示的动作能否延缓，分为延续性动词和终止性动词。
英语中，按动词延续的时间长短，可将动词分为延续性动词和短暂性动词。
延续性动词如learn, study, work, play, wait，have,,live,teach,keep,like 等。
短暂性动词是非延续性动词，即动作一开始便结束的动词，又可称结束性动词，瞬间动词，如leave, begin, start, return, arrive, reach, die, marry, bear, see, hear, receive, buy, get, enter, take off, start off, come in, come back, take place, break out, put on, put down, go in 等。
终止性动词构成的现在完成时，不可以用表示一段时间的状语（如：since 和for引导的短语）来修饰，终止性动词构成的现在完成时，只表示动作发生的因果关系，不能表示动作的延续，因此不能用表示一段时间的状语来修饰。
如可以说：The Red Cross has already started for the earthquake-stricken area.但不可说：The Red Cross has already started for the earthquake-stricken area for three days.因为start是终止性动词, 它所表示的动作短促, 当红十字会出发时，start这个动作便结束了, 不可能延续两天。
1. 用ago时间状语短语来代替since或for引导的时间状语：eg. Mr. Richard has returned from America for two years. (wrong) Mr. Richard has returned from America since two years ago. (wrong) 应改为: He returned from America two years ago.2．用It is… since…复合句代替简单句eg. It has been/is two years since Mr. Richard returned from America.注意：以上两种办法适用于所有终止性动词。

例如：How long _______ your brother joined the army?A. hasB. hadC. is it sinceD. was there that通过审题，答案B和D很容易被排除，但是稍不注意便会选中答案A；殊不知how long为一段时间的状语，不能与非延续性动词短语has joined连用，所以这题的正确答案是C。
另外，动词的延续性与非延续性还体现在这两种句型中：延续性动词的肯定式+till/ until 短暂性动词的否定式+till/ until请看例句：We waited until he came.I didn’t go to bed until my father came back home last night.如果短暂性动词与表示一段时间的时间状语连用，必须将短暂性动词改为延续性动词。
现归纳总结一下由非延续性动词到延续性动词的转换：arrive→behere begin(start)→be ondie →bedead come back→be backleave →be away (from) fallill(sick, asleep)→be ill(sick, asleep)get up→beup go out →be outfinish →beover put on →wear 或be onopen →be open join →be in或be a member of…close →beclosed go to school→be a studentborrow→keep buy/get →havecatch(a cold)→ have(a cold) get to know →knowbegin tostudy→study come to work→workmove to → live in finish/end → be overcome to → be in sit down → be seatedmarry → be married dress → be dressed 等如：He has been a soldier for three years. 他参军三年了。
His father has been dead for two years. 他父亲去世二年了。
The film has been on for ten minutes. 电影已开始十分钟了。
We have studied English for three years. 我们（开始）学英语已三年了。
How long can I keep this book? 这本书我可以借多长时间？除了用上面的转化形式之外，还可以用其他的表达形式：A. It is/ has been+时间+since……（动词用过去式），B. 主语+谓语（过去时）+时间+ago。
例如：It’s five days since I received his letter.His father died three years ago.看一个句子可以用以下几种说法：他离开上海已经3天了。
He left Shanghai three days ago.He has been away from Shanghai for three days.He has been away from Shanghai since three days ago.It is/ has been three days since he left Shanghai.Three days has passed since he left Shanghai.几点注意事项:（1）have been(to)与have gone( to)的区别：have been(to)表示“去过某地（现在已经回来了）”，可用于各人称；have gone(to)表示“去某地了（说话时某人不在当地）”，可能在去的路上，可能已在某地，也可能在回来的路上，总之，人不在这里。
常用第三人称作主语。
，前者可与once ,never, several times等连用，后者则不能。
如：They have been to Beijing twice. 他们去过北京两次。
He has gone to Beijing . 他去北京了。
注意比较下面几组句子的意义：He has gone to Amercia. （他到美国去了。
他不在这里）He has been to Amercia. （他去过美国。
现已回来）He has been in Shanghai. （他在上海呆过。
现在不在上海）He has been in shanghai for years. （他在上海多年。
现在还在上海）He has taught English. （他教过英语现在不教了）He has taught English for years. （他教英语多年了。
现在还在教）（2）如单纯表示一段时间，或强调一段时间，虽有since一词，也不必用完成时。
如：It is two years since his father died.=His father has been dead for two years. 他父亲去世已有三年了。
（3）终止性动词现在完成时的否定式，已变成一种可以延续的状态，因此可以和表示一段时间的状语连用。
如：I haven't left here since 1997. 自从1997年以来，我一直没有离开过这儿。
