现在完成时讲解及练习题(含答案)(word版可编辑修改)编辑整理：尊敬的读者朋友们：这里是精品文档编辑中心，本文档内容是由我和我的同事精心编辑整理后发布的，发布之前我们对文中内容进行仔细校对，但是难免会有疏漏的地方，但是任然希望（现在完成时讲解及练习题(含答案)(word版可编辑修改)）的内容能够给您的工作和学习带来便利。

同时也真诚的希望收到您的建议和反馈，这将是我们进步的源泉，前进的动力。

本文可编辑可修改，如果觉得对您有帮助请收藏以便随时查阅，最后祝您生活愉快业绩进步，以下为现在完成时讲解及练习题(含答案)(word版可编辑修改)的全部内容。

时态讲解：现在完成时（1）构成:现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化.第三人称单数用has，其余用have.现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。

以study 为例，其否定式、疑问式和简单回答形式如下：（2）用法:1)现在完成时通常表示在说话之前已经完成的动作或存在的状态。

说话人强调的是该动作或状态对现在的结果或影响.My daughter has just gone out. 我女儿刚出去。

I’m sure we’ve met before。

我肯定我们以前见过面。

She has arrived。

她到了。

2）表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently， already, just, lately，for…, since…,yet等。

如：I haven’t heard from her these days。

这些日子我没有收到她的信。

We haven’tseen you recently。

最近我们没有见到你。

They have been away for two years。

他们离开已经两年了。

She has been withus since Monday。

since的用法总结以下是小编为大家整理的since的用法总结,希望可以帮助到你们提高英语水平!since释义prep.从…以来; 自从…之后; 自从;adv.以后，此后; 后来; (距今几年)以前; (从那时候起几年)以前conj.自从…以来; 自从…的时候起; 既然; 因为since的用法一.Since作为介词后接某一确定的时间点，主句谓语动词是持续性动词，常与现在完成时态、现在完成进行时态或过去完成时态连用。

例如：1.He left the village in 1982 and I haven’t seen him since then.1982年他离开这个村子，从那以后我再没见过他。

2.She’s been working in a bank since leaving school.她中学毕业后就一直在一家银行工作。

3.He had spoken to her only once since the party. 自从那次聚会以来，他只跟她说过一次话。

二.Since作为副词表示从过去以来、以后或到现在的情形或状态，常与现在完成时态连用。

例如：1.He left home two weeks ago and we haven’t heard from him since. 他两周前离开了家，到现在我们一直没有他的消息。

2.He came to Zhenjiang 6 years ago and has lived here (ever) since.他6年前来到镇江，从此便住在这里。

三.since引导原因状语从句作为连词，since可引导原因状语从句，表示因为;既然;鉴于：例如：1.He didn’t come since he was busy.他因为忙，所以没有来。

2.Since this method doesn’t work,let’s try anoter.既然这种方法不行，我们就试用另一种吧。

第九讲：介词一、【考点解读】介词是一种用来表示词与词、词与句之间的关系的虚词，在句子中不能单独作成分。

介词后面一般有名词代词或相当于名词的其他词类，短语或从句作它的宾语。

介词和它的宾语构成介词词组，在句中作状语、表语、补语或介词宾语。

介词可以分为时间介词、地点介词、方式介词、原因介词和其他介词。

介词是英语中最活跃的词类之一，特别是一些常用介词的搭配力特别强，可以用来表示各种不同的意思。

二、【知识讲解】Mrs. Smith’s kitchenMrs. Smith’s kitchen is small.There is a refrigerator in the kitchen.The refrigerator is white.It is on the right.There is an electric cooker in the kitchen.The cooker is blue.It is on the left.There is a table in the middle of the room.There is a bottle on the table.The bottle is empty.There is a cup on the table, too.The cup is clean.知识点1——时间介词at, on, in 的用法1. at（1）表示具体时刻，如：at three o’clock在三点钟at half past eight在八点半（2）固定搭配：at noon at night at dawn at duskat the moment at first at the beginning at presentat last at sunrise at sunset at the age ofat the same time at dinner-time at the end of at Christmas2. on（1）表示具体某一天（包括节假日），如：on March 8th, 2016在2016年3月8日on Children’s Day在儿童节(at the Spring Festival)on Sunday在星期天（2）表示具体某一天的早、中、晚，如：on Saturday morning在周六早上on a rainy evening在一个下雨的傍晚on a hot afternoon在一个炎热的下午3. in（1）表示月份，季节，年，年代，世纪，如：in July在七月in summer在夏天in 2016 在2016年in the 1990s在20世纪90年代in the 21st century在21世纪in his twenties在他20多岁（2）后面跟一段时间，表示“…..之后”，指将来的时间，如：in a week 一周之后in a few months 几个月之后I’ll be back in a few minutes. 我几分钟后回来。

一般过去时态和现在完成时态的区别练习题1）一般过去时态表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时态中动作为过去发生的，强调过去的事情对现在的影响，强调的是影响。

如:I saw this film yesterday. （强调看的动作发生过了）I have already seen this film.（强调对现在的影响，电影的内容已经知了）I haven’t finished my work yet. (强调对现在的影响，还有工作要做，不能去玩) When did you finish your homework? (询问过去的动作所发生的时间，与现在无关)2）一般过去时态表示动作在过去已经停止；现在完成时态表示过去开始的动作一直延续到现在。

如：Ann visited her uncle last weekend.(visit这个动作在过去已经停止) They have lived here since 1983.(live here 这个动作从1983年开始，一直延续到现在)3）一般过去时态常用非延续性动词，如borrow, buy, come, go, leave, start, die, finish, become等。

现在完成时态可表示持续到现在的动作或状态，与时间段连用时动词一般是延续性的，如keep, have, live, teach, learn, work, study, know, be等。

如：He joined the League three years ago .(join是短暂动词）He has been in the League for three years.（be in表状态，在团内的状态可延续）He has been a League member for three years. （是团员的状态可延续）4）一般过去时态常与具体的时间状语连用，而现在完成时态通常与模糊的时间状语连用，或无时间状语。

for since because as 选择题在英语中，for、since、because和as都可以用来表示原因或理由，但在使用上存在一些区别。

下面我将为您解释它们的区别，并给出一些选择题。

for通常用于表示一个较长的时期或一系列事件的原因或理由。

通常用于说明某个动作或状态的原因或目的。

since通常用于表示某个时间点或某个事件发生后一直持续的原因或理由。

通常用于强调某个动作或状态已经发生或存在了一段时间。

because通常用于表示直接的原因或理由，强调因果关系。

通常用于回答why的问题。

as通常用于表示原因或理由，但强调的是一种伴随关系或同时发生的情况。

通常用于说明某个动作或状态发生的原因或目的。

以下是一些选择题，请根据您对每个选项的理解进行选择：We have to stay at home _____ the bad weather.A. forB. sinceC. becauseD. asI didn't go to the party _____ I was tired.A. forB. sinceC. becauseD. asI have been a teacher _____ I was a child.A. forB. sinceC. becauseD. asHe left early _____ he had to pick up his daughter from school.A. forB. sinceC. becauseD. asHe didn't come to the meeting _____ he was ill.A. forB. sinceC. becauseD. as。

Since 和 for 都可用于完成时，而 ago 只能用于过去时，其中 since 后面连接的是一个时间点，可以是一个具体的年月日或事件，而 for 后面连接的是一个时间段，不一定是确定的时间，但必须是一段时间。

从词性和连接时间来看，since 可以是介词、连词或副词，而 for 只是介词，ago 是副词，因此答题的关键是从时态和词性出发。

一、用 since，for 或 ago 完成下列的句子1、Claire is in Poland now. She has been there _____ two weeks.2、Claire has been in Poland _____ May and she is still there.3、Claire went to Poland two weeks _____.4、Matthew is studying in his room.

for since的用法“哎呀，老师，这个 for 和 since 到底怎么用啊，我老是搞混。

”学生小明皱着眉头问我。

“哈哈，小明啊，别着急，听老师给你慢慢讲。

For 和 since 呢，都是用来表示时间的，但它们的用法还是有些区别的。

For 后面通常加一段时间，比如说 for two hours，for three days 等等。

它强调的是这个时间段的长度。

咱举个例子啊，I have been waiting for an hour. 我已经等了一个小时了。

这里就是用 for 来表示等了一个小时这个时间段。

”“那 since 呢，老师？”小明紧接着问道。

“Since 就不一样啦，它后面接的是一个具体的时间点，比如 since yesterday，since last week，since 2010 等等。

它强调的是从那个时间点开始到现在的这段时间。

比如说，He has been working here since 2015. 他从 2015 年就开始在这里工作了。

你看，这里就是用 since 表示从 2015 年那个时间点开始到现在。

”我耐心地解释着。

“哦，我好像有点明白了，老师。

那比如说，我想说我学英语已经有三年了，应该用 for 还是 since 呀？”小明思考着问。

“嗯，这时候应该用 for 哦，因为三年是一段时间嘛，你可以说 I have been learning English for three years. 如果要说从三年前开始学，那就用since，I have been learning English since three years ago. 这下清楚了吧？”“清楚啦，清楚啦，老师。

那再比如，说我从早上就开始做这个作业了，怎么说呀？”“那就是 I have been doing this homework since this morning. 因为早上是个时间点呀。

Because,since,as,for的用法区别在英语中，because,since,as,for都可以用来表示原因或者理由，但是它们之间有一些细微的差别。

本文将介绍它们的用法区别，并给出一些例句和练习题，匡助您掌握它们的正确使用方法。

一、becausebecause是最常用的表示原因或者理由的连词，它可以连接两个句子，也可以连接一个句子和一个短语。

because后面的从句通常是主要的信息，而前面的主句通常是次要的信息。

因此，如果想强调原因或者者理由，可以把because从句放在句首。

例如：- He didn't go to school because he wassick.（他没有去上学，因为他生病了。

）- Because he was sick, he didn't go toschool.（因为他生病了，他没有去上学。

）二、sincesince也可以用来表示原因或者理由，但是它比because更正式，而且通常用于已经为人所知或者不言自明的情况。

since后面的从句通常是已经发生或者已经确定的事实，而前面的主句通常是对这个事实的结果或者推论。

因此，如果想强调结果或者推论，可以把since从句放在句首。

例如：- She has been very popular since she won the Nobel Prize.（自从她获得了诺贝尔奖，她就非常受欢迎。

）- Since she won the Nobel Prize, she has been very popular.（她获得了诺贝尔奖，因此她非常受欢迎。

）三、asas也可以用来表示原因或者理由，但是它比since更正式，而且通常用于书面语言中。

as后面的从句通常是对前面主句的解释或者补充，而且两个句子之间的逻辑关系比较密切。

因此，如果想强调解释或者者补充，可以把as从句放在句首。

例如：- He was late for the meeting, as he had missed thebus.（他迟到了会议，因为他错过了公交车。
