第一篇:小升初一般现在时课件讲解
一般现在时的特征是1.表示事物或人物的特征、状态。如:The sky is blue.天空是蓝色的。2.表示经常性或习惯性的动作。如:I get up at six every day.我每天六点起床。3.表示客观现实。下面是小升初一般现在时课件讲解,欢迎参考阅读!
一.概念
时态是英语谓语动词的一种形式,表示动作发生的时间和所处的状态.英语中的时态是通过动词形式本身的变化来实现的.英语有16种时态,但中学阶段较常用的有十种:一般现在时,一般过去时,一般将来时,过去将来时,现在进行时,过去进行时,将来进行时,过去完成时,英在完成时和现在完成进行时.二.相关知识点精讲
1.一般现在时的用法
1)经常性或习惯性的动作,常与表示频腮度的时间状语连用。时间状语: every…, sometimes, at…, on Sunday。例如:
I leave home for school at 7 every morning.每天早上我七点离开家。
2)客观真理,客观存在,科学事实。例如:
The earth moves around the sun.地球绕太阳转动。
Shanghai lies in the east of China.上海位于中国东部。
3)表示格言或警句。例如:
Pride goes before a fall.骄者必败。
注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。
例:Columbus proved that the earth is round.哥伦布证实了地球是圆的。
4)现在时刻的状态、能力、性格、个性。例如:
I don't want so much.我不要那么多。
Ann writes good English but does not speak well.安英语写得不错,讲的可不行。
比较:Now I put the sugar in the cup.把糖放入杯子。
I am doing my homework now.我正在做功课。
第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。
2.一般过去时的用法
1)在确定的过去时间里所发生的动作或存在的状态。例如:时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。例如:
Where did you go just now? 刚才你上哪儿去了?
2)表示在过去一段时间内,经常性或习惯性的动作。例如:
When I was a child, I often played football in the street.我是个孩子的时候,常在马路上踢足球。
Whenever the Browns went during their visit, they were given a warm welcome.那时,布朗一家无论什么时候去,都受到热烈欢迎。
3)句型:It is time for sb.to do sth “到……时间了” “该……了”。例如:It is time for you to go to bed.你该睡觉了。
It is time that sb.did sth.“时间已迟了” “早该……了”,例如It is time you went to bed.你早该睡觉了。
would(had)rather sb.did sth.表示'宁愿某人做某事'。例如:I'd rather you came tomorrow.还是明天来吧。
4)wish, wonder, think, hope 等用过去时,作试探性的询问、请求、建议等,而一般过去时表示的动作或状态都已成为过去,现已不复存在。例如:I thought you might have some.我以为你想要一些。
比较:Christine was an invalid all her life.(含义:她已不在人间。)
Christine has been an invalid all her life.(含义:她现在还活着)
Mrs.Darby lived in Kentucky for seven years.(含义:达比太太已不再住在肯塔基州。)
Mrs.Darby has lived in Kentucky for seven years.(含义:现在还住在肯塔基州,有可能指刚离去)
注意: 用过去时表示现在,表示委婉语气。
1)动词want, hope, wonder, think, intend 等。例如:
Did you want anything else? 您还要些什么吗?
I wondered if you could help me.能不能帮我一下。
2)情态动词 could, would。例如:
Could you lend me your bike? 你的自行车,能借用一些吗?
3.一般将来时
1)shall用于第一人称,常被will 所代替。will 在陈述句中用于各人称,在征求意见时常用于第二人称。例如:
Which paragraph shall I read first? 我先读哪一段呢?
Will you be at home at seven this evening? 今晚七点回家好吗?
2)be going to +不定式,表示将来。
a.主语的意图,即将做某事。例如:What are you going to do tomorrow? 明天打算作什么呢?
b.计划,安排要发生的事。例如:The play is going to be produced next month。这出戏下月开播。
c.有迹象要发生的事。例如:Look at the dark clouds, there is going to be a storm.看那乌云,快要下雨了。
3)be +不定式表将来,按计划或正式安排将发生的事。例如:
We are to discuss the report next Saturday.我们下星期六讨论这份报告。
4)be about to +不定式,意为马上做某事。例如:
He is about to leave for Beijing.他马上要去北京。
注意:be about to do 不能与tomorrow, next week 等表示明确将来时的时间状语连用。
4.一般现在时表将来
1)下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来,主要用来表示在时间上已确定或安排好的事情。例如:
The train leaves at six tomorrow morning.火车明天上午六点开。
When does the bus star? It stars in ten minutes.汽车什么时候开?十分钟后。
2)以here, there等开始的倒装句,表示动作正在进行。例如:
Here comes the bus.= The bus is coming.车来了。
There goes the bell.= The bell is ringing.铃响了。
3)在时间或条件句中。例如:
When Bill comes(不是will come), ask him to wait for me.比尔来后,让他等我。
I'll write to you as soon as I arrive there.我到了那里,就写信给你。

现在完成时的时间状语:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不确定的时间状语。

第三篇:一般现在时精品课件
一般现在时是初中英语阶段一个重要的语法知识点,也是学生理解其他相关时态的基础和保证,让我们一起来看看吧,下面是小编帮大家整理的一般现在时精品课件,希望大家喜欢。
一、教学内容:一般现在时
二、教学步骤:
1、导入:同学们,前面我们陆续已经学习了好几个语法,我们一起来回忆下都有哪些?(板书:名词;be动词;代词;用英语表达“有”)。现在我们一起来欣赏一篇文章
2、新课(PPT)My Family
There are four people in my family.They are my father, mother, sister and I.I am a student.I like English.I always go to school on foot.My father is a driver.He likes reading book.My mother is a nurse.She works in No.1 hospital.Usually , my mother goes to work by car.My little sister is a cute baby.She can sing and dance.We like sports and we often run in the morning.What about you?
Ok,我们一起来看下红色部分的单词like—likes--like go—goes;这些单词有什么不同?它们的意思是一样的吗?有变化吗?对了,没有,意思没变,这些变化都是由语法造成的,动词的变化不会影响意思。这个语法就是我们今天要学的一般现在时。
什么是一般现在时呢?我们昨天做的事叫过去时,现在做的事叫现在进行时,明天或以后做的事,叫将来时,那什么是一般现在时呢? 吃饭,你昨天吃了,今天吃不吃,明天又吃不吃? 睡觉,你昨天睡觉了,今天睡觉吗,明天还睡觉吗?学习,你昨天学习了,今天还要学习,明天还是要学习。这些事情都是经常要做的事情,就叫一般现在时,还有一种情况也是,就是真理性的东西,比如,the moon goes around the sun.月亮绕着太阳转 the sky is blue.天空是蓝色的 I am a chinese.我是一个中国人 you are a student.你是一个学生 she is my mother.她是我妈妈。
那我们如何判断这句话是不是一般现在时呢?我们可以看时间状语。
经常做的事情,如,我走路去上学,这句话还不够清晰,你是天天走路去上学呢还是有时走路去上学,为了把我们做的事表达的更清楚,我们经常会加上一个时间状语的单词。如:I go to school on foot everyday.I usually go to school on foot.那这些表示时间的单词一般有以下几个:
every每个(everyday每天 everyyear每年 …), always总是,usually通常, often经常, sometimes有时;这些单词按频率由多到少是:比如:我走路去上学,10天内,天天走路,那就是everyday;有9天是走路,那就是always;有8天走路,就是usually;7天,often;3-4天,就用sometimes.现在我们倒回来看看刚才我们学习的文章,谁能找出那些句子是一般现在时?是的,这篇文章的句子都是一般现在时,那有些是没有时间状语的呢,一般来说,没有时间状语的80%都是一般现在时。一般现在时有什么特别的地方?不同的人称后面,动词会变化,如:
We like sports and we often run in the morning.—人称:we 是第一人称复数
He likes reading book.– 人称:he 是第三人称单数
I like English.I always go to school on foot.– 人称:I 是第一人称单数
She works in No.1 hospital.– 人称:she是第三人称单数
Usually , my mother goes to work by car.– 人称:my mother 是第三人称单数
第三人称单数(除I we you 外的单数)很孤独,后面的动词加多个s或es给它做伴。到底动词加多个s还是es给它做伴呢?请记住以下规则:这个规则跟我们的名词变复数有几点是一样的。
三单变化1)多数在动词后加s: play—plays like—likes
2)以s,o,x,sh,ch结尾的动词加es go—goes wash—washes
3)以辅音字母加y结尾,把y改i再加es fly—flies
这里我们要特别注意have 的第三人称单数是 has。has 的原形是have
只有第三人称单数用动词三单,其余动词均用原形.We like English.She likes English.(一)练习:写出下列动词的第三人称单数形式
(单词的第三人称单数变化主要看最后一个字母)
1.work___ read___ clean__ write___ 这一组最后一个字母都不在我们的规则里,所以直接加s
2.teach__ wash___guess___watch___ 这一组最后一个字母是ch,sh,s,ch,变化规则里有一条是这样说的,sos sh ch结尾的加es,所以加es
3.go__ do__这一组最后一个字母是o,变化规则里有一条是这样说的,sos sh ch结尾的加es,所以加es
4.study___fly___cry___play___这一组都是以y结尾,变化规则里有一条是这样说的,以辅音加y结尾,把y变i加es.这里study fly cry 这三个单词都是以辅音加y 结尾,所以 加es.但是 play 是原音加y,不属于这个规则,所以直接加s.5.have______ have 的第三人称单数是has。它是不符合规则变化的,has的原形就是have.(二)用括号里的动词填空
(在句子里我们怎么判断动词的用法呢?记住以下几个步骤:第一,找时间状语,判断是什么时态;第二找人称,决定动词的用法;第三,第三人称单数动词的变化)
1.We often___________(play)in the playgound.第一,时间状语:often,是一般现在时;第二,人称:we动词用原形
2.Danny(study)English,Chinese,Maths,Science and Art at school.第一,时间状语:无,是一般现在时;第二,人称:Danny是第三人称单数,动词要变化;study 是以辅音加y 结尾,把y 变i加es
3.He _________(get)up at six o’clock everyday.第一,时间状语:everyday,是一般现在时;第二,人称:he是第三人称单数,动词要变化;get 最后一个字母是t 所以直接加s
4.Mike sometimes ______(go)to the park with his sister.第一,时间状语:sometimes,是一般现在时;第二,人称:Mike是第三人称单数,动词要变化;go 是以o 结尾,加es3、否定句
前面学there be 时我们曾做过把有变成没有,否定句。还记得步骤吗?
第一,找be,第二,在be后加not, 第三,some/ many 变any.其它照抄.1、There is a book on the desk.--There is not a book on the desk.2、There are many apples on the tree.—There are not any apples on the tree.3、There is some water in the bottle.--There is not any water in the bottle.在我们今天学的一般现在时里,也有be,它变否定也是一样的。步骤:第一,找be,第二,在be后加not, 第三,some/ many 变any.其它照抄.这里还有一个单词can 变否定跟be是一样的。所以我们这的步骤要稍微变一下,记下来:第一,找be或can,第二,在be或后加not, 第三,检查有没some/ many,有的话要把some/ many 变any.其它照抄.

导语:别想把一切都弄清楚,再去走路。比如路上有很多障碍,将其清理到你能走过去就好,无需全部清除干净。以下小编为大家介绍一般现在时公开课课件文章,欢迎大家阅读参考!
一般现在时公开课课件
现在一般时(present tense)概念:表示通常性、规律性、习惯性、真理性的状态或者动作(有时间规律发生的事件)的一种时间状态。
常用结构:
1.主语+谓语+其他(表动作)
It never snows in Australia in December.澳大利亚的12月里从来不下雪。
They usually go to school by bike.他们通常骑自行车上学。
He writes to his father twice a month.他每月写两次信给他爸爸。
2.主语+be+表语(表状态)
He is a student.他是学生。
ⅠBe动词的一般现在时
主语+be(am , is , are)+其它
肯定句式:主语+be(am, is, are)+其它.如,The color is blue.否定句式:主语+be(am, is, are)+not +其它.如,The color is not blue.一般疑问句:Be(am, is, are)+主语+其它?.注:在这种构成中,be动词有人称和数的变化,即要根据主语选用am / is / are。Be动词分为单数和复数,am和is是表示单数,am只跟I搭配(除了I其余的单数都用is),are表示复数。
Ⅱ 实义动词的一般现在时
① 主语(第三人称单数)+动词(第三人称单数形式)+其它
肯定句式:主语(第三人称单数)+动词(第三人称单数形式)+其它,如,He likes it

第五篇:一般现在时练习题及答案讲解
一般现在时练习题及答案讲解
一般现在是在英语中应用最多的一个时态,也是初中英语学习中的重点内容,在考试中经常会出现。所以老师对于学生们一般现在时练习题的练习和讲解都是非常重视的,只有多做一般现在时练习题大家才能真正的掌握这个时态中的所有知识。
大家在做一般现在时练习题之前,首先要了解的就是它的定义是什么,什么情况下会用到这个时态。也就是说一般现在时的讲解是非常重要的,只有大家了解了该时态的用法,才能去做一般现在时练习题,通过练习完全的掌握这个时态,才能应对考试以及中考。很多老师对于该时态的讲解也非常重视的,下面小编就和大家分享一下该时态的讲解:
它表示1)经常性、习惯性的动作或存在的状态。eg.I go to school on foot.He is very busy now.2)表示主语的特征、性格、能力、爱好等。eg.He can swim.I work hard.I like watching TV.3)表示客观真理 eg.There are seven days in a week.The moon moves round the earth.其结构按正常语序,即“主语+谓语+其它”,有时为了起强调作用,时间状语也可提前.其句式变化可分为两种情况 1)表示动作,一般人称作主语的,变否定句须在动词前加助动词don’t;变一般疑问句须在句首加助动词do。E.g.They have lunch at 12:00.They don’t have lunch at 12:00.Do they have lunch at 12:00? 2)单三人称做主语的,变否定句须在动词前加助动词doesn’t;变一般疑问句须在句首加助动词does。
E.g.Jenny speaks English very well.Jenny doesn’t speak English very well.Does Jenny speak English very well? 含有be动词的要在be上做变化.E.g.Danny is a good student.Danny isn’t a good student.Is Danny a good student? 其时间状语为often、usually、always、sometimes等频率副词,on Saturdays、in the morning(afternoon evening)、every day 等。
以上就是一般现在时的讲解以及它的结构介绍,相信大家对于该时态都有所了解了,但是大家在做一般现在时练习题以及考试的时候经常会出现一些错误,这些错误都是比较容易混淆的知识点,这也造成了很多学生的丢分。所以大家一定要经常的去练习,根据习题的解析去了解更多关于该时态的知识。那么针对这些容易出错的情况,小编也结合一般现在时的练习题以及解析给大家做出讲解:
学生常见错误如下:
一、be动词与行为动词同时出现在句子中
例:We are ______(plant)the trees in spring.答案:plant 解析:学生往往会用汉语的思维方式去翻译,就成了“我们是在春天植树”。这是学习英语最忌讳的,要看语法是不是正确,在英语中,be是表状态,do是表动作,两种动词不能同时出现在句子中,可记住如下口诀:“英汉语言有差异,be、do不能放一起,仔细琢磨细分析,语法千万要牢记。”
自我检测:(一)、单选 Jenny ____ in an office.Her parents ____in a hospital.A work;works B works;work C work;are working D is working;work 2 One of the boys_____ a black hat.A have B there is C there are D has 3 We will go shopping if it____ tomorrow.A.don't rain B.didn't rain C.doesn't rain D.isn't rain 4 He said the sun ____in the east and ____in the west.A rose;set B rises;sets C rises, set D rise;sets 5 Wang Mei ____ music and often ____ to music.A like;listen B likes;listens C like;are listening D liking;listen 6 Jenny____ English every evening.A has study B studies C study D studied 答案:1 B 2D 3C 4B 5B 6B(二)、填空 I can take Li Ming there when he _____(come)to visit.2 _____your sister_____(know)English? 3Her home____ _____ ______(远离)her school.4The pot_____(not look)like yours very much.5 Where _____you____(have)lunch every day? 6 Who_____(想要)to go swimming? 7 ______she_____(do)the housework every day? 8 Jenny and Danny usually______(play)games in the afternoon.答案:1 comes 2 Does know 3 is away from 4 doesn't look
二、单三人称形式易出错
例:1 He ______(play)football very well.2 Danny ________(go)to school at 7:10.答案:1 plays 2 goes 解析:1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es;2与名词变复数不同,变单三人称形式以o结尾的词要加es.三、在句式变换时易出错
例:1 _____ Jenny _____(has)a good friend? 2 Brian _______(not live)in China.答案:1 Does have 2 doesn’t live 解析:单三人称做主语的一般现在时做句式变化时,可记住如下口诀:“见助动,用原形”。此口诀也可推广用于一般过去时态中。e.g.He didn't go home yesterday.四、对do的理解易出错
例:We don’t(not do)our homework in the afternoon.答案:don’t do 解析:do是一个比较难理解的词,它有三个含义: a)是所有行为动词的总称;b)是助动词,无实义;c)是一个具体的行为动词“做,干”。此句中给出的do指“做,干”,not指把此句变为否定句,故须在do前加助动词don’t。
五、对主语的数判断有误
例: Li Ming with me are(be)in Beijing.答案: is 解析:表面一看是“我和李明两个人在北京”,但with在此做伴随状语,不能做主语,故用is.
