同學(xué)們,從三四年級(jí)起,我們就結(jié)識(shí)了“be”動(dòng)詞,并與“be”動(dòng)詞結(jié)下了“不解”之緣。今天,就讓我們一起走進(jìn)“be”動(dòng)詞訓(xùn)練營(yíng),來(lái)解開心中的“不解”吧!
“be”動(dòng)詞的一般現(xiàn)在時(shí)有三種形式:am, is, are。為了幫助大家掌握,我把“be”動(dòng)詞的用法編成了朗朗上口的順口溜:“我用am,你用are, is用在他她它(I—am, you—are, he/she/it—is);單數(shù)形式用is,復(fù)數(shù)形式就用are。”
例句:
I am a new student.
What are you doing?
She is good at English and Math.
What is your job?
What are their jobs?
到了六年級(jí),我們又學(xué)習(xí)了“be”動(dòng)詞的一般過(guò)去時(shí)?!癰e”動(dòng)詞的過(guò)去式共有兩種形式:was(am,is的過(guò)去式) 和were(are的過(guò)去式)。順口溜在過(guò)去時(shí)態(tài)的用法中又可以改編成:“我用was,你用were,was用在他她它(I—was, you—were, he/she/it—was);單數(shù)形式用was,復(fù)數(shù)形式就用were?!?/p>
例句:
I was at school yesterday.
You were here just now.
It was there a moment ago.
Were there any fruit trees on the farm?
同學(xué)們,最后,我們把“be”動(dòng)詞的否定結(jié)構(gòu)及其縮寫形式整理一下吧。
isn’t=is not ? aren’t=are not
wasn’t=was not ? ? weren’t=were not
現(xiàn)在,你是否對(duì)be動(dòng)詞不再疑惑了呢?讓我們一起來(lái)檢驗(yàn)一下吧!
