一般现在时和一般过去时

一般现在时讲解及练习1、定义与讲解一般现在时:表示经常性的事情,经常性的动作或一般性事实。
时间状语:often 经常,usually通常,always 总是,every+名词每个,sometime s 有时,once a week ,on Sundays ,if 的从句at …在几点钟2. 表示客观真理,科学原理,自然现象,等客观事实或格言,谚语等。
The sun rises in the east and sets in the west every day.The man who has never been to the Great Wall is not a real man.Tomorrow is Tuesday.只有在第三人称单数用动词的“三单变化”,其他用动词的原形。
三单变化:(1)直接在动词词尾加-s.ask---asks work---works get---gets stay---stays(2)以字母s, x, ch, sh或o结尾的动词,在词尾直接加-es.watch---watches wish---wishes fix---fixes pass---passes(3)以“辅音字母加- y”结尾的动词,要先变y为i再加-es.try---tries study---studies cry---cries fly---flies play —plays2.不规则变化:be---- is are have----has do---does go---goes三、一般现在时的句子转换:(1)当句子中有be动词或情态动词时,则把be 动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句陈述句She is a student.疑问句Is she a student? 否定句She is not a student.陈述句:I can swim.疑问句→ Can you swim否定句→ I can not swim.(2)当句子中即没有be动词,也没有情态动词时,则在主语前加助动词do (you,以及复数), does(单数she,he,it)变成问句;在主语后谓语动词前加助动词don’t(I, you,以及复数), doesn’t(单数she,he,it)变成否定句,助动词后的动词要变成动词原形。
如何区分一般现在时

如何区分一般现在时、现在进行时、一般过去时、一般将来时、一、一般现在时:概念:经常、反复发生的动作或行为及现在的某种状况。
例:He listens to the radio every evening.时间状语:always, usually, often, sometimes, every week (day, year, month…), once a week, on Sunday, etc.基本结构:①be动词;②行为动词否定形式:①am/is/are +not;②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
二、一般过去时:概念:过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为。
例:I wasborn on April 2, 1986.时间状语:ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just now, at the age of 5, one day, once upon a time, etc.基本结构:①be动词;②行为动词否定形式:①was/were +not;②在行为动词前加didn't,同时还原行为动词。
一般疑问句:①was或were放于句首;②用助动词do的过去式did 提问,同时还原行为动词。
三、现在进行时:概念:表示现阶段或说话时正在进行的动作及行为。
时间状语:at the monment look listen\now例:The woman is talking to the doctor.时间状语:now, at this time, these days, etc.基本结构:am /is/are +doing否定形式:am /is/are +not +doing.一般疑问句:把be动词放于句首。
一般过去时和一般现在时的知识梳理

一般过去时和一般现在时的知识梳理一般过去时和一般现在时是英语中最基本的两种时态,它们用来描述不同的时间状态。
下面将分别对这两种时态进行详细的梳理。
一、一般过去时1. 一般过去时的基本用法一般过去时用来描述过去某个时间发生的动作或存在的状态,通常和表示过去的时间状语连用,如yesterday(昨天)、last week (上周)、two years ago(两年前)等。
例如:- I went to the park yesterday.(我昨天去了公园。
)- They studied English last night.(他们昨晚学习了英语。
)2. 一般过去时的构成一般过去时的肯定句结构为“主语+ 动词过去式+ 其他”,否定句结构为“主语+ did not + 动词原形+ 其他”,疑问句结构为“Did + 主语 + 动词原形 + 其他”。
例如:- He played basketball with his friends.(他和朋友们打篮球。
)- They did not watch the movie.(他们没有看那部电影。
)- Did you visit your grandparents last weekend?(你上周末去看望你的祖父母了吗?)3. 一般过去时的时间状语一般过去时常常和表示过去的时间状语连用,如yesterday(昨天)、last month(上个月)、in 1999(在1999年)等。
时间状语可以出现在句首、句中或句末。
例如:- Last night, I watched a movie.(昨晚,我看了一部电影。
)- He lived in New York for five years.(他在纽约住了五年。
)二、一般现在时1. 一般现在时的基本用法一般现在时用来描述当前的状态、习惯或经常发生的动作。
它表示的是客观事实或普遍真理,与时间无关。
例如:- The sun rises in the east.(太阳从东方升起。
一般现在时和一般过去时区别

一般现在时和一般过去时的区别他每天都来。
He comes every day.他昨天来了。
He came yesterday.他已经来了。
He has come.他明天来。
He will come tomorrow.从上面几句话可以看出,汉语是借助词汇手段而不是词的形态变化来表示动作的发生,如“每天”,“昨天”,“已经”,“明天”等,而英语主要通过谓语动词时态变化来表现。
任何句子都要先注意时态。
记住常见的几种时态的标志词:现在咱们先来聊聊一般现在时和一般过去时的区别:一、一般现在时概念:经常、反复发生的动作或行为及现在的某种状况。
时间状语:always, usually, often, sometimes, every week (day, year, month...), once a week, on Sundays, etc.基本结构:一般现在时通常是以动词原形表示的,但在主语为第三人称单数时,动词词尾要加-s或-es,规则如下:(1)当动词以-s, -ss, -sh, -ch, -x, -o结尾时,加-es。
如:kiss—kisses wash—washes teach—teaches box—boxes go—goes (2)当动词以“辅音字母+y" 结尾时,改y为i再加-es,如:carry—carries fly—flies try—tries study—studies(3)动词be的一般现在时表现形式是:am, is, are, 根据人称和数的不同而分别采用。
(4)have的第三人称单数形式是has。
(5)除上述情况外,其余动词在词尾加-s。
一般现在时的用法:1、表示客观真理和科学事实、格言以及其他没有时间限制的客观存在。
如:Twice two is four. 2的两倍是4。
The Great Wall is the longest wall in the world. 长城是世界上最长的城墙。

时态知识点一般现在时一般过去时等时态知识点:一般现在时、一般过去时等时态是语法中非常重要的一个概念,用来表达动词所表示的动作或状态在时间上的情况。
一般现在时和一般过去时是时态中最基本的两种,下面将对它们进行详细讨论。
一、一般现在时(Simple Present Tense)一般现在时用来表示经常发生的事件、普遍的真理、现实存在的状态或习惯等。

- 对于以辅音字母加"y"结尾的动词,要将"y"改为"i"并加上"-es";对于以元音字母加"y"结尾的动词,直接加上"-s"。
二、一般过去时(Simple Past Tense)一般过去时用来表示过去发生的动作或状态,常常与具体的时间状语连用,如yesterday、last week等。
1. 表示过去发生的事件:例如:- I visited my grandparents last weekend.- They watched a movie together yesterday.2. 表示过去的习惯或状态:例如:- He used to live in New York.- She had a pet dog when she was a child.3. 表示过去的真理、科学事实或历史事件:例如:- The dinosaurs became extinct millions of years ago.- Columbus discovered America in 1492.4. 表示间接引语中的陈述句:例如:- He said he loved her.注意事项:- 对于大多数动词,我们只需要在动词原形的基础上加上"-ed"。
