be动词用法详解
am、is用于主语表单数概念的句中(主语是you除外)。
第一人称单数I配合am来用,常见句型“I am+…”;第三人称单数He、 She 、 It配合is使用,常见句型“She/He/It is +…”如:
I am ten years old.
I am a boy.
She is a good girl.
He is so thin.
It is a dog. 它是一只狗。
Are主要用于主语表复数概念的句中
Are主要用于主语表复数概念的句中(包括一些简单集体名词,如:people,family),第二人称(You)配合are使用,常见句型:“You are+…”
如:
You are great.
Amy and Mary are sisters.艾米和玛丽是姐妹。
The family are all at home.全家人都在家。
There are many apples on the tree. 树上有很多苹果。
代词you是一个单复数同形词,既可表示“你”,又可表示“你们”,所以避免混淆,总是跟are做朋友。
