现在完成时中的since与for
现在完成时中的since与forSince 用来说明动作起始时间，for用来说明动作延续时间长度。
I have lived here for more than twenty years.I have lived here since I was born..My aunt has worked in a clinic since 1949.Some new oilfields have been opened up since 1976.I have known Xiao Li since she was a little girl.My brother has been in the Youth League for two years.I have not heard from my uncle for a long time.注意：并非有for 作为时间状语的句子都用现在完成时。
I worked here for more than twenty years.(我现在已不在这里工作。
)I have worked here for many years.(现在我仍在这里工作。
)小窍门：当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。
1)(对) Tom has studied Russian for three years.= Tom began to study Russian three years ago, and is still studying it now.2)(错) Harry has got married for six years.= Harry began to get married six years ago, and is still getting married now.显然，第二句不对，它应改为 Harry got married six years ago.或 Harry has been married for six years.。

since的时态用法总结
since的时态用法总结
since是一个介词，通常用来表示一个事件或时间点开始的时间。
它可以用在不同的句子结构中，表达不同的时态意义。
以下是since 的常见时态用法总结：
1. 现在完成时：在肯定句中，since用来表示动作开始的时间，一直延续到现在。
例：我认识他已经五年了。
-> I have known him for five years.
2. 过去进行时：在过去进行时的肯定句中，since用于表示过去某个时间点开始的动作，且该动作在过去时间一直延续。
例：杰克在我认识他的那天就一直在学习。
-> Jack has been studying since the day I met him.
3. 现在进行时：在现在进行时的肯定句中，since表示动作的起始时间。
例：他们从上午九点半起就一直在开会。
-> They have been having a meeting since 9:30 AM.
4. 过去完成时：在过去完成时的肯定句中，since表示动作开始的时间，一直延续到过去的某一点。
例：我们昨天一直在等待他，因为他迟到了。
-> We had been waiting for him since yesterday because he was late.
总之，since的时态用法与上下文和句子的结构有关。
根据需要，可以根据动作的开始时间和是否延续来选择适当的时态。
for和since现在完成时的用法
“for”和“since”在现在完成时中的用法如下：
“for”用于表示一个时间段，即动作持续的时间长度。
它通常与表示时间的名词（如年、月、日、小时等）连用，表示某个动作或状态持续了多长时间。
例如：“I have lived here for five years.”（我已经在这里住了五年了。
）
“since”用于表示一个时间点，即动作开始的时间。
它通常与表示过去某个时间点的词语（如从句、过去分词等）连用，表示某个动作或状态从何时开始一直持续到现在。
例如：“I have not seen him since last year.”（自从去年以来我就没有见过他。
）
需要注意的是，“for”和“since”在现在完成时中的用法是有所区别的，需要根据具体语境进行区分。
同时，在使用现在完成时时，还需要注意动词的正确形式，以及与时间状语的搭配等问题。
现在完成时for 和since用法
现在完成时二用法：过去完成时表示过去发生的动作或存在的状态一直持续到现在（包括现在在内），常与for和since引导的时间状语连用，动词需要用延续性动词。
如：Mr.Green has been in China for 10 years .(格林先生来中国10年了)The film has been on for 20 minutes.(电影开始已经20分钟了)Since 与for的区别：for后面跟一段时间如：for three days for 2 years 等+ 过去的时间点：since 2004Since+ 一段时间ago ：since two minutes ago+ 过去时的句子：since I came to this school用since 和for 填空：1.I have kept the book _______ a week , I must return it on time .2.We have learned English _______ 5 years ago, so we have learned it ______ 5 years.3.Miss Li has taught maths ________ she came to this school ..4.I have had a cold _______ yesterday.5.The workers have worked _______ 10 hours . They are very tired.6.Great changes have taken place in China ______ it was founded.7.Our teacher has studied Japanese ______ three years.8. She has been away from the city ______ about ten years.9.. It’s about ten years __________ she left the city.短暂性动词的完成时态不能和表示一段的时间状语连用，当它需要与表示一段时间的时间状语连用时，通常需进行转化，见书119页。
since for的用法时态
since for的用法时态一、since for的用法介绍Since和for是英语中常见的时间状语从句，用于描述一个事件或动作发生的时间或持续的时间段。
它们在使用时会根据特定的情境和语义需求来决定使用哪个。
1. since的用法Since通常用来表示一个事件或动作从过去某个具体时间点开始一直延续到现在。
它可以接完整的时间短语、具体日期、或者动词过去式等表达方式。
例如：- I have been studying English since last year.（我从去年开始一直在学习英语）- She has been living in London since she graduated from university.（她从大学毕业后就一直住在伦敦）2. for的用法For则表示一个事件或动作已经持续了多长时间，通常配合表示持续时间段的表达方式来使用，如年、月、周、天等。
例如：- He has been working at this company for five years.（他已经在这家公司工作五年了）- They have been dating for over a month.（他们已经约会了一个多月了）两者都是表示时间段，但是since强调起始点，for则强调持续的时间长度。
二、since and for 的区别与搭配1. 区别不同之处主要在于所指代的含义不同。
Since强调时间的起点，对于某个具体事件或时间点的回溯。
而for则侧重表示已经过了多长时间，持续的时长。
2. 搭配a. since的常见搭配- since + 具体时间短语/日期：表示从某个特定过去时间开始到现在所经过的时间段。
例如：- I have known him since we were kids.（我认识他自从我们还是孩子）- She has been working here since Monday.（自从星期一以来，她一直在这里工作）- since + 过去时/现在完成时动作：表示某个事件或状态从过去某个时间点开始并持续至今。
since的用法时态句型
since的用法时态句型"since"的主要用法是引导时间状语从句，指示一个事件或时间点的起始，并且可以与不同的时态和句型搭配使用。
1. 现在完成时：since + 过去的时间点/时间段- I have been living in this city since 2024.（我自2024年开始住在这个城市。
）- They have known each other since they were in high school.（他们自高中时就认识彼此。
）2. 过去完成时：since + 过去的时间点/时间段- I had been studying English for five years since I moved to Canada.（自从我搬到加拿大后，我已经学习英语五年了。
）3. 一般过去时：since + 过去的时间点/时间段- We have been friends since we met at college.（我们自从上大学时就是朋友。
）- She had been living in London since she left her hometown.（她离开家乡后一直住在伦敦。
）4. 一般将来时：since + 将来的时间点/时间段- We will have been together for two years since we get married next month.（下个月我们结婚后，我们在一起已经两年了。
）需要注意的是，"since"引导的时间状语从句中的动词通常采用过去时，但如果主句中的动词本身已经表示了过去的内容，则从句中的动词可以使用现在完成时或过去完成时。
现在完成时和since
2016.2.221、since的用法：(1)接时间点：（延续性动词）例：I have stayed in that country since 1995.(2)接一段时间 + ago：（延续性动词）例：They have lived in that house since two years ago.(3)接时间状语从句：例：I have loved her since I met her last time. / Lily has stayed at home since she left school.要求：主句的谓v.用现在完成时，而且须是延续性动词；从句的谓v.用一般过去时，而且须是终止性动词。
(4)用于句型“It’s / It has been + 一段时间 + since + 时间状语从句”中：例：It’s / has been three months since he moved to this city.要求：主句的谓v.用一般现在时或现在完成时;从句的谓v.用一般过去时，而且须是终止性动词。
(5)用于句型“一段时间 + has passed since + 时间状语从句”中：例：Three months has passed since he moved to this city.要求：主句的谓v.用现在完成时，而且动词必须是has passed；从句的谓v.用一般过去时，而且须是终止性动词。
（注：当since用于否定句时，主句的谓v.可以是终止性动词。
例：He hasn’t seen the film since last month. ）(7)相关词组：“从那时起”:ever since、since then、from then on ：（注：ever since作为一个词组，放句尾可单独使用。
例：I have given up smoking ever since. ）另外，还可在since后接句子。
(完整版)Since和for的用法及区别
Since 和for 的用法及区别：一，since 的四种用法1，since + 过去一个时间点（如具体的年、月、日期、钟点、ago. 1990 , last month , half past six I have been here since 1990. 1990起，我一直在这儿。
2，since+ 一段时间+agoI h a v e b e e n h e r e s i n c e f i v e m o n t h s a g o。
自从五个月前，我已经在这儿了。
3，since+从句GreatChanges have taken place since you left. 自从你走后，已经发生了很大的变化。
4，It is +一段时间+since从句I t i s t w o y e a r s s i n c e I b e c a m e a n E n g l i s h t e a c h e r.我成为英语老师有两年了。
二，Since 和for区别1，Since +时间点，具体时间“自从I have been in Beijing since 2010.、以来，从、、、以后”用来说明动作起始时间2，For + 时间段，用来说明动作延续时间长度，因此句中的谓语动词，也应该是延续性动词。
I have been in Beijing for one year。
We have learnt English for about three years.I have been here for 3 days. (对)I have arrived here for 3 days.（误）三，延续性动词和终止性动词的概念英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和终止性动词。
延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。
如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep,live, stay等。
《现在完成时中since和for的用法》知识讲解
《现在完成时中s i n c e和f o r的用法》《现在完成时中since和for的用法》微课讲课稿一、引入新课同学们好，本节课我们主要学习现在完成时中since和for的用法二、学习for的用法首先，我们来看两个句子Number OneI came to this school last week. 我上周六到这所学校Number TwoI have been in the new school for a week. 我到这所新学校已经一周了我们来看一下，第一句中的last week用于一般过去时的句子，第二句中的for a week用于现在完成时的句子。
a week 是一个时间段,因此我们用“for+时间段”来表达一段时间。
那同学们看一下，如果我们把第一句话中的last week 改成last year，那么第二句话中的for a week该改成什么呢？对，应该变成for a year.三、学习since的用法接下来，我们再看两个句子Number OneLily left home last Friday. 丽丽上周五离开家Number TwoLily has been away from home since last Friday. 丽丽自从上周五已离开家我们来看一下，第一句中的last Friday是过去的一个时间点，因此这句话用一般过去时表达，而第二句中since last Friday 用在现在完成时的句子中，last Friday 是一个过去的时间点，因此我们用“since +时间点”来表达一段时间它有三个具体用法，我们来详细学习一下1、since+过去一个时间点，如具体的年月、星期、小时。
eg：1990、last night、half past six我们来看一个例句：I have been here since 1990. 我自1990年以来一直在这里1990是过去的一个时间点，since 1990, 就是since+过去一个时间点来表达一段时间的第一个用法2、since+一段时间+ago，表示“自···时间前开始至今”我们来看一个例句：He has been here since five years ago. 他在这儿已经有5年了five years 是一段时间，since后不能直接跟时间段，但后面再跟ago是可以的，因此since five years ago 就是since+时间段+ago来表达一段时间的第二个用法3、since+一般过去时从句我们来看两个例句Number OneMany things have changed since you left. 自从你走后许多事情发生了变化“you left”是一个一般过去时从句。
现在完成时的持续型用法
现在完成时的持续型用法现在完成时还可表示过去某一时间开始并一直持续到现在(包括“现在”在内)的动作或状态，该用法中的动词多是延续性动词，常见的时态标志词有since和 for。
1. since意为“自从……以来”，它既可作介词，也可作连词。
作介词时，后接表示过去的时间点，表示某事开始的时间；作连词时，引导时间状语从句，从句常用一般过去时。
如：Mr. Miller has lived here since five years ago.（since+时间段+ago）I have had the dictionary since I was ten.(since+“一般过去时”)2. for作介词，后接一段时间，表示一个动作或一种状态已经持续了多长时间。
如：Miss Green has taught in the village for three years.Kate has been here for two hours.注意：1. 对since和 for引导的时间状语提问时，常用how long。
如：I have worked here for two years. (对划线部分提问)How long have you worked here?2. 在现在完成时中，含有for和since的句子可以相互转换。
如：Mary has been in Beijing for two days.（for+时间段）=Mary has been in Beijing since two days ago.（since+时间段+ago）3. 在现在完成时中，表示短暂意义的动词(如come和see)在肯定句和一般疑问句中不能和表示一段时间的时间状语连用，但在否定句中是可以的。
如：Bill has come here for an hour. (×)I haven’t seen Kate for three years. (√)4. It has been / It’s +时间段+since从句(一般过去时). 表示:“自从……以来，有多长时间了。
现在完成时以及for,since的用法
for +一段时间表示时间的持续 强调一段时间 have / has been + doing sth + since +过去的时间点 表示“自从过去某一时间 点以来” 强调动作或状态一直延续到现在 since + 从句 (一般过去时) 表示从过去开始一直持续到现在的动作，并有可能持续下去．与过去时的比较：1.I watched TV for three hours.我看了三小时的电视．（我现在没有看电视了）2.I have been watching TV for three hours. 我看了三小时的电视．（我现在仍然在看电视）一．用for 或者since 填空。
填空。

现在完成时用法——持续性用法
现在完成时用法——持续性用法现在完成时用法——持续性用法-—持续性用法（肯定句，疑问句中谓语动词必须是延续性动词）：表示过去已经开始，持续到现在的动作或状态。
此时常与“for＋一段时间或“since＋过去的点时间或从句(从句用一般过去时)以及so far（到目前为止）等时间状语连用。
for + 段时间since +点时间实例:1)I've lived here since 1990．自从1990年以来我就住在这里。
= I’ve lived here since 13 years ag o。
= I’ve lived here for 13 years。
= It is 13 years since I began to live here.2)I haven’t seen him for three years．我三年没有看见他了。
= I haven’t seen him since three years ago.= It is 3 years since I saw him last time。
3)Mr Wang has worked in the factory since he came to the city ．自从到这个城市以来，王先生一直在这家工厂工作。
4)She’s been at this school since five years ago．自从五年前以来她就在这个学校.注意：①在这类句子的肯定句和疑问句中谓语动词必须用延续性动词。
短暂性动词由于动作不能持续，故不能与for（达到；累计）或since（自从。
到现在）引出的时间状语连用。
②对for和since引导的时间状语提问要用How long1）他入团两年了。
误：He has joined the League for two years．正：He has been a League member for two years．2）我买这辆自行车三年了。
