4A语法Be动词.doc

4A语法（四）：Be动词 am，are，is 这三个动词称为Be动词。这三个单词的意思都翻译成“是”。要注意在句子中由于主语人称的不同，be动词要做相应的变化。主语是单数第一人称单数时，be动词是am；主语是第三人称单数时，用is；主语是其他人称代词时用are。另外，be动词的意思是“是”，但在汉语中往往不翻译出来。 例句：I am fine, thank you. Are you a bus-driver?He is my teacher.We are good friends.歌谣：我(I)用am，你(you)用are, is用于他她它(he, she, it)，我们(we)，你们(you)，他们(they)都用are,单数用is,复数用are.一、练习：用动词be （am， are， is）填空1. I _ a boy. _ you a boy?
