在一般现在时中，be动词有三种形式：
am、is、are，它们的意思均为“是”。
★ am、is、are“各侍其主”
am只“忠于”第一人称单数代词 I，“绝无二心”。
① I am in Grade 7.
② I am happy.
③ I am 12 years old.
动词be的一般现在时
Presentation
is“交友”甚广，可以为第三人称单数代词he、 she、 it及单数名词服务，也可与表示单数意义的指示代词this或that搭档。
① He is from the US.
② She is so beautiful.
③ It is Ms Gao.
④ The kite is in the tree.
⑤ Is this your classmate
Presentation
are也与指示代词复数these、those等搭配。
These are the pictures from our holiday.
are“人缘”最好，和第二人称代词you的关系最铁；与第一、三人称复数代词we、they或表示复数意义的名词关系也很好。
① We are very happy with new friends.
② They are hungry and they are ready to eat.
③ You are very friendly.
④ The grapes are sweet.
Presentation
Be动词有三兄弟 (am, is, are),
I (我) 用am, you (你) 用are,
is连着he (他), she (她), it (它),
单数名词用is, 复数名词全用are。
