am用于第一人稱單數(shù)I之后；is用于第三人稱單數(shù)ge，she，it以及相當(dāng)于he，she或it；are用于第二人稱或所有人稱的復(fù)數(shù)，表達(dá)“是”的意思�？捎孟旅娴目谠E來幫助記憶：“我用am你用are，is用于他她它，復(fù)數(shù)全都要用are”。

I am…可以縮寫成I'm，he is可以縮寫成 he's，she is可以縮寫成加she's，it is可以縮寫成it's，而we are，you are，they are可分別編寫成we're，you're，they're。am，is，are的否定形式是在后面加not，如：am not，is not，are not。is not通常縮寫為isn't，而are not通�？s寫為aren't。如：

(1)I'm Alice, I'm not Mary. She's Mary.
