系动词
1.系动词又叫连系动词，本身有词义，但不能单独作谓语，必须和表语一起构成谓语，说明主语的状态、性质、特征或身份。
2.系动词在小学阶段主要是be动词。
3.be动词必须和主语在人称和数上保持一致。
I用am, you用are; is用于“他、她、它”；
所有复数都用are。

be 动词的定义

be 动词的种类
1.be动词可以和主语一起写成缩写。
如：I am＝I'm, you are＝you're, he is＝he's, she is＝she's, they are＝they're等。
2.但要注意，不是所有的主语都可以和be动词缩写，不能缩写的要特殊记忆。
如：This is不能写成This's; I am not不能缩写成I amn't。
Yes后面的简略回答都不能缩写，如“Yes, he is.”不能写成“Yes, he's.”，“Yes, we are.”不能写成“Yes，we're.”等。
be动词的否定形式：
am not(没有缩写形式)，
is not＝isn't,are not＝aren't。
was not＝wasn't,were not＝weren't。

be动词考点
思路点拨：考查be动词。
第1题一般疑问句的主语为you，所以be动词用Are；答语中主语为I，be动词用am。
第2题中主语为he，一般疑问句中用Is；答语中由No可知是否定回答，用isn't。
第3题中Jim and I 是复数，用动词are。
第4题his football是第三人称单数形式，用动词is。
第5题前一句中由one year ago可知是说明过去的状况，用过 去式was，后一句讲现在的情况，用am。
【答案】 1.Are; am　2.Is; isn't　3.are 4．is　5.was; am
