同學(xué)們,從三四年級起,我們就結(jié)識了“be”動詞,并與“be”動詞結(jié)下了“不解”之緣。今天,就讓我們一起走進(jìn)“be”動詞訓(xùn)練營,來解開心中的“不解”吧!
“be”動詞的一般現(xiàn)在時有三種形式:am, is, are。為了幫助大家掌握,我把“be”動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?!?/p>
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,我們又學(xué)習(xí)了“be”動詞的一般過去時。“be”動詞的過去式共有兩種形式:was(am,is的過去式) 和were(are的過去式)。順口溜在過去時態(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be動詞不再疑惑了呢?讓我們一起來檢驗(yàn)一下吧!
練一練:請用be動詞的適當(dāng)形式填空。
