初一、初二英语时态讲解与练习

句子的时态是通过动词的变化来表现的,通过观察一个动词的不同形式可以看出句子的时态,表明发生的时间。有些时态可以通过时间状语来确定,有些则根据常识来确定。

一、一般现在时

1. 表示方法:主语除了三单以外的人称用动词原形,主语是三单(he, she, it,人名、物名)时,动词的表示方法与名词的复数形式是一样的,即动词的三单。

动词的三单变化:一般在动词后加-s; 以s, x, o, sh, ch 结尾的加es; 以辅音字母加y 结尾的,变y为i,再加es; 以f, fe结尾的变f, fe为v, 再加es。

2. 哪些情况下用一般现在时

1)表示经常性、习惯性的动作;表示现在的状态、特征和真理。句中常用often, usually, always, seldom, every…,sometimes, every day/morning/Sunday, on Sunday等时间状语。例如:

a. He goes to school every day. 他每天去上学。

b. He is very happy. 他很开心。

c. The earth moves around the sun. 地球围绕太阳转。(特性)

2) 在时间状语从句和条件状语从句中,用一般现在时表示将来。例如:

a. If you come this afternoon, we’ll have a meeting. 如果你今天下午过来,我们将开个会。

b. When I graduate, I’ll go to countryside. 毕业后我要去乡下。

3) 有时这个时态表示按计划、规定要发生的动作(句中都带有时间状语),但限于少数动词,如:begin, come, leave, go ,arrive, start , stop, return, open, close等。例如:

a. The meeting begins at seven. 会议七点开始。

b. The rain starts at nine in the morning. 上午九点开始下雨。

4) 表示状态和感觉的动词(be, like, hate, think, remember, find, sound 等)常用一般现在进行时。

a. I like English very much. 我非常喜欢英语。

b. The story sounds very interesting. 这个故事听起来很有趣。

总的说:表示习惯、爱好、频率(经常、总是、偶尔)、规律、事实动词用一般现在时。3. 动词的一般现在时的肯定句、否定句、疑问句

1)be动词的一般现在时am, is, are

否定句:在am, is, are加not 一般疑问句:把am, is, are提到句首

I am a teacher. I’m not a teacher. Are you a teacher?

She is a beautiful girl. She isn’t a beautiful. Is she a beautiful girl?

They are careful students. They aren’t careful students. Are they careful students? 2)实意动词的一般现在时

肯定句:主语除了三单以外的人称用动词原形,主语是三单(he, she, it,人名、物名)时,动词的表示方法与名词的复数形式是一样的,即动词的三单。

否定句:三单在动词原形前加doesn’t, 其余人称加don’t

疑问句:一般在句首加Do, 三单在句首加Does后动词还原。

I like English. I don’t like English. Do you like English?

My mother teaches English. My mother doesn’t teach English

Does your mother teach English?

二、一般过去时的用法

1. 表示方法:用动词的过去式表示

动词的过去式的表示方法:

be动词的过去式:was, were

实意动词的过去式:一般在动词后加-ed; 以e结尾的加-d, 以辅音字母加y结尾的,变y 为i加ed, 以重读闭音节结尾的双写末尾的辅音字母加ed.

特殊的动词的过去式如take-took等要记忆。

2. 哪些情况下用一般过去时

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, just now, once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)在时间状语从句中,由when引导从句的瞬间性动词用一般过去时,主句常用过去进行时。

I was watching TV when the rainstorm suddenly came.( 瞬间性动词)

Ben was helping his mom make dinner when the rain began to beat heavily against the windows. ( 瞬间性动词)

4)注意:情态动词用过去时表示现在,表示委婉语气。例如: could, would

Could you lend me your bike? 你的自行车,能借用一些吗?

重点学习一下,used to / be used to

used to + do:"过去常常"表示过去习惯性的动作或状态,但如今已不存在。例如:Mother used not to be so forgetful. 老妈过去没那么健忘。

Scarf used to take a walk. 斯卡夫过去常常散步。

be used to + doing:对……已感到习惯,或"习惯于",to是介词,后需加名词或动名词。例如:

He is used to a vegetarian diet.

Scarf is used to taking a walk. 斯卡夫现在已习惯于散步了。

典型例题

---- Your phone number again? I ___ quite catch it.

---- It's 69568442.

A. didn't

B. couldn't

C. don't

D. can't

答案A. 本句虽没有明确的时间状语,但从语意上看出,在听的时候没有听懂这个动作发生在过去,因此应用过去时。

3. 一般过去时的否定句和疑问句

was, were的否定句直接在后面加not, 疑问句把was, were提前。

实意动词的否定句在动词原形的前面加didn’t, 疑问句在句首加Did后动词还原。

She was a teacher three years ago.

She was not a teacher three years ago.

Was she a teacher three years ago?

I watched TV yesterday evening.

I didn’t watch TV yesterday evening.

Did you watch TV yesterday evening?

三、一般将来时的用法

1.一般将来时表示将来的动作或状态。其表达形式“ will 或shall + 动词原形”;表示即将发生的或最近打算进行的事,或某种迹象表明将要发生某事,其表达形式“ be going to+ 动词原形”。常用的时间状语tomorrow (morning/afternoon/evening);next year/month/week

a. Look at the clouds in the sky! It is going to rain. 要下雨了。(迹象)

b. We are going to have a meeting today. 我们今天要开个会。(打算)

C. We will have a meeting next Sunday.(将来)

2. 在When, as soon as, if 等引导的时间状语从句和条件状语从句中,时态是主将从现。例如:

a. If you come this afternoon, we’ll have a meeting. 如果你今天下午过来,我们将开个会。

b. When I gradu ate, I’ll go to countryside. 毕业后我要去乡下。

C. I will call you as soon as I arrive in Beijing.

四、现在进行时

1.表示方法:am/is/are(助动词)+v-ing(现在分词)

否定句:am/is/are +not+v-ing

疑问句:把am/is/are提到句首

2. 现在分词的构成

一般在动词后加-ing如:work -- working,sleep -- sleeping ,study --studying;

以e结尾的去e加ing take --taking ,make --making,dance --dancing;

重读闭音节的动词,要双写词尾字母,再加-ing cut ----- cutting put ----- putting begin ------ beginning

以-ie结尾的动词,把变成y再加-ing lie ----- lying tie ----- tying die ----- dying

初中英语动词时态讲解及练习

16种英语时态总结归纳 时态(Tense)是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。 英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时。 1. 一般现在时 用法:A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。C) 经常性、习惯性动作。 例:He always helps others. (他总是帮助别人。) D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词)可以与表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。 例:The next train leaves at 3 o'clock this afternoon.(下一趟火车今天下午3点开车。) How often does this shuttle bus run? (这班车多久一趟?) F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情。 例:When you have finished the report, I will have waited for about 3 hours.(等你完成这份报告的时候,我就已经等了将近3个小时了。) 2. 现在进行时(be doing) 用法:现在正在进行的动作。 3. 现在完成时(have done) 用法: A) 表示动作到现在为止已经完成或刚刚完成。 例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for 加一段时间,或by加一个现在时间。 例:Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是:“虽然牛顿是个伟大的人物,但他的许多见解直到今天还在受到挑战,并且被现代科学家的工作所修正。”challenge是及物动词,在本句中应当是被动语态;其动作延续到今天,所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging都是主动语态,不可能是答案。B) may be challenged虽然是被动语态,但意思与全句内容不合,所以不对。 C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。 例:John has broken his left leg.(约翰摔断了左腿。) 注意事项 A) 现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于:现在完成时强调动作的动态,或受动态的影响,是动态的结果,对现在有影响;过去时只表示过去的某个具体时间里发生的动作,与现在没有联系。

初中英语时态讲解(完整版)

英语时态讲解 1. 一般现在时的应用 (1) 表示经常发生的动作或存在的状态。常用频度副sometimes, often, always, usually, seldom 以及时间副词 every day / night / week / month / year, in the morning, in the afternoon, in the evening, at night 做状语。如: He often stays up late. 他常熬夜。 We go home every month. 我们每月都要回家。 I watch TV at night. 我晚上看电视。 (2) 表示客观真理或永恒的状态。如: The earth travels round the sun. 地球绕太阳旋转。 Trees turn green in spring. 春天树木变绿。 Liquid turns into gas when it is hot enough. 足够热时,液体变为气体。 Practice makes perfect. 熟能生巧。 (3) 现阶段的状态。常跟时间副词now连用。如: He lives in Beijing now. 他现在住在北京。 She is at home. 她在家。 They work in that factory. 他们在那家工厂工作。 (4) 习惯性的爱好或行为。如: I like dancing while she likes singing. 我喜欢跳舞,而她喜欢唱歌。 We get up at six. 我们六点起床。 He studies very hard. 他学习很刻苦。 (5) 表示已经计划、安排好了或时间表上所安排,并且一定要做的事情。用于这种句型的动词主要是瞬间动词:come, go, leave, arrive, begin, start, stop, close, open等。如: The train arrives at five past eight and leaves at ten past eight. 火车八点过五分到,八点过十分

初一英语一般现在时态讲解 一、定义与讲解 一般现在时表示经常或习惯性的动作或一般性事实。也可表示现在的状态或主语具备的性格和能力。 通常与副词every day(每天),always(总是),usually(通常),often(经常)sometimes(有时),等时间状语连用。 例:(1)表示事物或人物的特征、状态。 The sky is blue.天空是蓝色的。 Mary’s father is a n English teacher. 玛丽的爸爸是一名英语老师。 (2)表示经常性或习惯性的动作。 I go to school at seven every day.我每天六点去上学。 She plays sports every day. 她每天都做运动。 (3)表示客观现实。 The table has four legs.桌子有四条腿。 There are 63 students in my class. 我们班有63个学生。 (4)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 every day.太阳每天从东方升起。 The earth goes around the sun.地球绕着太阳转。 (5)表示平日的喜好。 I like bananas. We don’t like vegetables. He likes blue. She doesn’t like strawberries. 二、只有主语在第三人称单数时在陈述句里面实义动词用“三单形式”, 其他人称(一,二,三复)用动词原形。 e.g. I/ We like English very much.我/我们非常喜欢英语。 She/ He/His sister l ikes English very much. 她/他/她的妹妹非常喜欢英语 ★动词三单形式的变化规则: 1.(1)多数直接在动词词尾加-s. play — plays like — likes ask---asks work---works get---gets call---calls (2)以字母s, x, ch, sh或o结尾的动词,在词尾直接加-es. watch---watches wash---washes do---does go---goes (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 2.不规则变化:be---- is have----has 一般现在时态肯定句式:分为含有be动词和实义动词的两种情况:

初中英语八大时态总结

初中英语八大时态总结 一、一般现在时 具体情况(主要用于下面几情况) 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 在这种情景中,句子常带有表示频率的时间状语:always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等,以表示句中的动作或状态是习惯性的、经常性的。例如: They raise ducks as a sideline .他们以养鸭为副业。 It seldom rains here .这儿很少下雨。 2)仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态",其重点"不是强调动作发生的时间、或进行的状态"。例如: He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 3) 陈述客观事实、客观真理。 顾名思义,客观的情况是"没有时间概念"的;也"不会在意动作进行的状态"。例如: The sun rises in the east .日出东方。 4) 根据英文语法规定,当主句的谓语动词是一般将来时,那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如: I'll tell him the news when he comes back. 他回来时,我将告诉他这个消息。 *【用于一般现在时的副词,除了上面提到的一些表示频率的以外,常见的还有:now, today , nowadays等等】 二、一般过去时 具体情况(主要用于下面几情况) 1.主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。 例:I was very thin in my childhood. 2.一般过去时由谓语动词的过去式表示,也就是说动词词末要加-ed(除不规则动词外)。常和一般过去时连用的过去时间状语有:last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 例:Did you meet yesterday? He left just now. 3.使用一般过去时,在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。"过去"的时间概念有两层意思:一是指"现在某个时间"以前的时间;二是指"说话、写文章的那个时间点"以前的时间 He got his driving license last month. 他上个月拿到了驾照。
