第二篇：初中英語一般現(xiàn)在時(shí)與一般過去式小結(jié)

一般現(xiàn)在時(shí)與一般過去式小結(jié)

一，一般現(xiàn)在時(shí)的用法

1)經(jīng)常性或習(xí)慣性的動(dòng)作，常與表示頻腮度的時(shí)間狀語連用。

時(shí)間狀語： every…, sometimes, at…, on Sunday

I leave home for school at 7 every morning.2)客觀真理，客觀存在，科學(xué)事實(shí)。

The earth moves around the sun.Shanghai lies in the east of China.3)表示格言或警句中。

Pride goes before a fall.驕者必?cái)　?/p>

注意：此用法如果出現(xiàn)在賓語從句中，即使主句是過去時(shí)，從句謂語也要用一般現(xiàn)在時(shí)。

例：Columbus proved that the earth is round..4)現(xiàn)在時(shí)刻的狀態(tài)、能力、性格、個(gè)性。

I don‘t want so much.Ann Wang writes good English but does not speak well.比較：Now I put the sugar in the cup.I am doing my homework now.第一句用一般現(xiàn)在時(shí)，用于操作演示或指導(dǎo)說明的示范性動(dòng)作，表示言行的瞬間動(dòng)作。再如：Now watch me, I switch on the current and stand back.第二句中的now是進(jìn)行時(shí)的標(biāo)志，表示正在進(jìn)行的動(dòng)作的客觀狀況，所以后句用一般現(xiàn)在時(shí)。

5）時(shí)間標(biāo)志詞： every …, sometimes, often usually 6）一般現(xiàn)在時(shí)中的動(dòng)詞第三人稱單數(shù)形式

在一般現(xiàn)在時(shí)中，當(dāng)主語是第三人稱單數(shù)時(shí)，謂語動(dòng)詞要用第三人稱單數(shù)形式，即常在動(dòng)詞原形后加-s或-es?，F(xiàn)歸納總結(jié)如下：

1、人稱代詞he, she, it是第三人稱單數(shù)。如： He likes watching TV.他喜歡看電視。She has lunch at twelve.她十二點(diǎn)吃午餐。It looks like a cat.它看起來像只貓。

2、單個(gè)人名、地名或稱呼作主語；是第三人稱單數(shù)。如： ①Han Mei looks like her mother.韓梅看起來像她的母親。②Beijing is in China.北京在中國(guó)。

③Uncle Wang often makes cakes.王叔叔經(jīng)常做蛋糕。

3、單數(shù)可數(shù)名詞或“this / that / the+單數(shù)可數(shù)名詞”作主語時(shí)，是第三人稱單數(shù)。如：

①A horse is a useful animal.馬是有用的動(dòng)物。②This book is yours.這本書是你的。③That car is red.那輛小汽車是紅色的。④The cat is Lucy's.這只貓是露茜的。

4、不定代詞someone, somebody, nobody, everything, something等及指示代詞this, that作主語時(shí)，是第三人稱單數(shù)。如： ①Everyone is here.大家到齊了。

②There is something wrong with the watch.這塊手表有毛病。③This is a pen.這是一支鋼筆。④That is an eraser.那是一塊橡皮擦。

5、不可數(shù)名詞作主語時(shí)為第三人稱單數(shù)。如： ①The milk is in the glass.牛奶在玻璃杯里。②The bread is very small.那面包很小。

6、當(dāng)數(shù)字或字母作主語時(shí)，看作第三人稱單數(shù)。如： ①“6” is a lucky number.“6”是個(gè)吉利數(shù)字。②“I” is a letter.“I”是個(gè)字母。

二，一般過去時(shí)的用法，1）在確定的過去時(shí)間里所發(fā)生的動(dòng)作或存在的狀態(tài)。

時(shí)間狀語有：yesterday, last week, an hour ago, the other day, in 1982等。

Where did you go just now?

2）表示在過去一段時(shí)間內(nèi)，經(jīng)常性或習(xí)慣性的動(dòng)作。

When I was a child, I often played football in the street.Whenever the Browns went during their visit, they were given a warm welcome.3）句型：

It is time for sb.to do sth

“到……時(shí)間了”

“該……了”

It is time sb.did sth.“時(shí)間已遲了”

“早該……了”

It is time for you to go to bed.你該睡覺了。

It is time you went to bed.你早該睡覺了。

would(had)rather sb.did sth.表示‘寧愿某人做某事‘

I‘d rather you came tomorrow.4)時(shí)間標(biāo)志詞：yesterday, last week, an hour ago, the other day, in 1982, just now 5）一般過去時(shí)：一般過去時(shí)的謂語動(dòng)詞要用動(dòng)詞的過去式形式。be動(dòng)詞的過去式有兩種：was(是is, am的過去式)，were(是are的過去式)；行為動(dòng)詞的過去式一般在詞尾加-ed；不規(guī)則變化的動(dòng)詞要參看不規(guī)則動(dòng)詞表。含有be的過去時(shí)，變否定句在was和were的后面加not。was not與were not可縮寫成wasn't和weren't。一般疑問句是把was/were提到句首，并大寫第一個(gè)字母w，句末用問號(hào)。

例： He wasn't in the classroom just now.剛才他不在教室。

— Were you at home last night?

— Yes, I was./ No, I wasn't.— 昨天晚上你在家嗎？

— 是的，我在。/ 不，我不在。

6）行為動(dòng)詞的過去時(shí)的否定句、一般疑問句怎樣改寫呢？這就要借助助動(dòng)詞do/does的過去式did了。否定句在did后加not, 并把行為動(dòng)詞恢復(fù)原形。如：

He didn't do his homework last night.昨天晚上他沒寫作業(yè)。

而一般疑問句要把did提到句首，行為動(dòng)詞也要恢復(fù)原形。如：

— Did you listen to the radio yesterday?

— Yes, I did./ No, I didn't.— 昨天你聽收音機(jī)了嗎？

— 是的，我聽了。/ 不，我沒聽。

第三篇：一般現(xiàn)在時(shí)的用法小結(jié)

一般現(xiàn)在時(shí)的用法小結(jié)

1、定義:一般現(xiàn)在時(shí)表示現(xiàn)在經(jīng)常反復(fù)發(fā)生的動(dòng)作、存在的狀態(tài)或習(xí)慣性的動(dòng)作。

2、構(gòu)成：一般現(xiàn)在時(shí)用行為動(dòng)詞的原形，但第三人稱單數(shù)作主語時(shí)，動(dòng)詞的詞尾要加-S或-es。

規(guī)則：以輔音字母加“y”結(jié)尾的詞，要把“y”變?yōu)椤癷”再加“es”，以“o s x ch sh ”結(jié)尾的詞加“es”，be動(dòng)詞的變化形式是am is are 一般現(xiàn)在時(shí)的用法：

1)經(jīng)常性或習(xí)慣性的動(dòng)作，常與表示頻度的時(shí)間狀語連用。

時(shí)間狀語： every?, sometimes, usually often once a week on sundays I leave home for school at 7 every morning.Sometimes,he plays baskateball with his father.She usually goes to school at 7:00.We often visit that old teacher on Sundays.2)客觀真理，客觀存在，科學(xué)事實(shí)。The earth moves around the sun.Shanghai lies in the east of China.3)表示格言或警句中。

Pride goes before a fall.驕者必?cái)　?/p>

No man but errs 注意：此用法如果出現(xiàn)在賓語從句中，即使主句是過去時(shí)，從句謂語也要用一般現(xiàn)在時(shí)。例：Columbus proved that the earth is round..4)現(xiàn)在時(shí)刻的狀態(tài)、能力、性格、個(gè)性。I don't want so much.Ann Wang writes good English but does not speak well.比較：Now I put the sugar in the cup.I am doing my homework now.第一句用一般現(xiàn)在時(shí)，用于操作演示或指導(dǎo)說明的示范性動(dòng)作，表示言行的瞬間動(dòng)作。再如：Now watch me, I switch on the current and stand back.第二句中的now是進(jìn)行時(shí)的標(biāo)志，表示正在進(jìn)行的動(dòng)作的客觀狀況，所以后句用一般現(xiàn)在時(shí)。

在一般現(xiàn)在時(shí)中，當(dāng)主語是第三人稱單數(shù)時(shí)，謂語動(dòng)詞要用第三人稱單數(shù)形式，即常在動(dòng)詞原形后加-s或-es。但有些同學(xué)們對(duì)于哪些主語是第三人稱單數(shù)還不十分清楚，現(xiàn)歸納總結(jié)如下：

三、單數(shù)可數(shù)名詞或“this / that / the+單數(shù)可數(shù)名詞”作主語時(shí)，是第三人稱單數(shù)。如：

①A horse is a useful animal.馬是有用的動(dòng)物。②This book is yours.這本書是你的。③That car is red.那輛小汽車是紅色的。④The cat is Lucy's.這只貓是露茜的。

四、不定代詞someone, somebody, nobody, everything, something,nothing等及指示代詞this, that作主語時(shí)，是第三人稱單數(shù)。如： ①Everyone is here.大家到齊了。

②There is something wrong with the watch.這塊手表有毛病。③This is a pen.這是一支鋼筆。④That is an eraser.那是一塊橡皮擦。

五、不可數(shù)名詞作主語時(shí)為第三人稱單數(shù)。如： ①The milk is in the glass.牛奶在玻璃杯里。②The bread is very small.那面包很小。

六、當(dāng)數(shù)字或字母作主語時(shí)，看作第三人稱單數(shù)。如： ①“6” is a lucky number.“6”是個(gè)吉利數(shù)字。②“I” is a letter.“I”是個(gè)字母。

在下列情況下表示將來：

1.在狀語從句中用一般現(xiàn)在時(shí)代替一般將來時(shí)。如：

I will give it to him as soon as I see him.我一看見他就交給他。He will come if you invite him.如果你請(qǐng)他,他會(huì)來的。

Suppose he doesn’t agree，what shall we do?假如他不同意，那怎么辦? I shall do as I please.我高興怎么做就怎么做。

He will continue the work no matter what happens.不管發(fā)生什么情況他都要繼續(xù)這項(xiàng)工作。2.在the more…the more …(越……越……)句型中,前者通常用一般現(xiàn)在時(shí)代替一般將來時(shí)，因?yàn)榍罢呦喈?dāng)于條件狀語從句。如：

The harder you study, the better results you will get.你學(xué)習(xí)越努力，成績(jī)就會(huì)越好。

3.在make sure(certain), see to it, mind, care, matter后的賓語從句的謂語動(dòng)詞用一般現(xiàn)在時(shí)代替一般將來時(shí)。如：

See to it that you are not late again.注意別再遲到了。

4.表示按計(jì)劃或時(shí)間表將要發(fā)生的動(dòng)作，通常有表示將來的時(shí)間狀語。如：

The plane takes off at 11:30 and arrives in Shanghai at l:20.飛機(jī)十一點(diǎn)半起飛，一點(diǎn)二十分抵達(dá)上海。

注：只限于少數(shù)動(dòng)詞能這樣用，如 begin, start, , end, finish, stop, go, come, leave, sail, arrive, return, close, open 等。

例：We are students.（我們是學(xué)生）

口訣：一般時(shí)態(tài)有關(guān)be動(dòng)詞的口訣

我用am，你用are，is連接他/她/它，復(fù)數(shù)形式就用are

第五篇：一般現(xiàn)在時(shí)和現(xiàn)在進(jìn)行時(shí)的用法+動(dòng)詞單三形式

5、現(xiàn)在進(jìn)行時(shí)用法口訣

主語在句首，am, is, are跟在后，現(xiàn)在分詞跟著走，其他成分不可丟。表示動(dòng)作正進(jìn)行，句中now時(shí)間定。一般問句，把be提到句前去。否定句式也簡(jiǎn)單，be后只把not添。
