(this?is?不能縮寫)
are you/we/they you're/we're/they're
通過表格可以看出:be?動詞的形式隨主語的變化而變化,具體如下:
1.主語是第一人稱單數(shù)?I(我)時,be?動詞用?am,?I?am?可縮寫為?I'm。例如:
I?am/I'm?a?girl.?我是一個女孩。
2.主語是第三人稱單數(shù)、可數(shù)名詞單數(shù)或不可數(shù)名詞時,be?動詞用?is。he?is,?she?is,
it?is?和?that?is?可分別縮寫為?he's,?she's,?it's?和?t
4、hat's,this?is?不可以縮寫。例如:
He?is/He's?my?teacher.?他是我的老師。
Her?name?is/Her?name's?Jenny.?她的名字是詹妮。
注意:(1)be?動詞還可與其他詞縮寫,例如:?what?is=what's,?there?is=there's
等。be?動詞也可與?not?縮寫,例如:is?not=isn't,?are?not=aren't。?但?am?與?not?不
能縮寫。
(2)句中有?be?動詞時,變否定句時,在?be?動詞后加?not;變一般疑問句時,把?be?動詞
提
5、到主語之前。例如:
I?am?not?in?Class?One.?我不在一班。
Is?this?your?book??這是你的書嗎?
3.主語是?you(we,?they,?she?and?I,?these?等)或可數(shù)名詞復(fù)數(shù)(seven?coats,?many
pencils?等)時,be?動詞用?are。例如:
They?are?my?friends.?他們是我的朋友。
