现在完成时短暂性转换延续性
短暂性动词-延续性动词和现在完成时
短暂性动词-延续性动词和现在完成时短暂性动词，延续性动词和现在完成时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。
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；★在否定句中，短暂性动词可以和表示一段时间的状语连用。
We haven’t hea rd from Jane for a long time.★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。
★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：.I have received his letter for three days （×） I have received his letter.（√）How long did she leave .（×） How long has she been away? (√)★★★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。

例如：It’s five days since I received his letter.arrive →be herebegin(start)→be ondie →be deadcome back →be backleave →be away (from)fall ill(asleep)→beill( asleep) get up →be up go out →be out finish →be over put on →wear 或be on open →be open close →be closed join →be in/ be a member of go to school →be a student borrow →keep buy/get →have catch(a cold)→ have(a cold) get to know →know begin to study →study come to work →work move to → live in finish/end → be over come to → be in sit down → be seatedHis 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。

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。

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。

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。

现在完成时态的动词转换
延续性动词与瞬间动词的转换一、瞬间动词也叫短暂性动词或终止性动词。
这种动词是指它们动作的开始也就意味着动作的结束，所以不能直接跟表示一段的时间状语连用。
那么，如何使瞬间动词与表示一段时间的状语连用呢？此时，我们可以将这些词转换成意义相近的延续性词（组），从而间接表示其中的意思。
二、瞬间动词与延续性动词的区别：1、用于完成时的区别1）延续动词表示经验、经历；2）瞬间动词表示行为的结果，不能与表示段的时间状语连用。
eg. 1.He has completed the work.他已完成了那项工作。
(表结果)2.I've known him since then.我从那时起就认识他了。
(表经历)2、用于till和until从句的差异1）延续动词用于肯定句，表示“做……，直到……”2）瞬间动词用于否定句，表示“到……，才……”eg. 1.He didn't come back until ten o'clock. 他到10点才回来。
2.He slept until ten o'clock.他一直睡到10点。
三、瞬间动词到延续性动词的转换：这里对一些词做一些总结：瞬间动词可转换的延续性动词（组）arrive be herebegin/start be ondie be deadfall ill/sick/asleep be ill/sick/asleepget up be upgo out be outfinish be overput on wear或be onopen be open(adj.)join be in或bea member of…close be closedgo to school be a studentborrow keepbuy havecatch(a cold) have(a cold)get to know knowbegin to study studycome to work workget up be upleave be away from等如：1.He has been a soldier for three years. 他参军三年了。
