解析试题分析:
【小题1】本句前后主语都是单数第三人称,故系动词用is,填:is is  
【小题2】本句前文主语是单数第一人称,故系动词用am ,下文我的名词时单数名词,故系动词用is。
【小题3】he是单数第三人称,故系动词用is,you是第二人称,故系动词用are。
【小题4】you是第二人称,故系动词用are,I是第一人称,故系动词用am。
【小题5】this是单数,故系动词用is,it是单数第三人称,故系动词用is。
考点:系动词be的用法
点评:be动词往往根据句子的主语而有所不同,其应用原则可以结合如下歌谣来记忆;我用am,你用are;is用在他、她、它。单数名词用is,复数名词全用are。
