Unit 1School and Friends单元语法聚焦一be动词(am, is, are)在英语中，am，is，are统称为be动词。其中，am与I对应，可缩写为Im；is对应he，she，it，可缩写为hes, shes, its; are 用于第二人称you及表示复数概念的代词(如：we, they, she and I, these等)或复数名词(如：seven coats, many pencils)等之后。记住并理解下面的顺口溜，你便掌握了be动词的用法：“我”用am，“你”用are, is连着“他、她、它”；单数名词用is，复数名词都用are。变疑问，往前提，句末问号莫丢弃。变否定，更容易，be后not莫忘记。疑问否定任你变，句首大写莫迟疑。.单项选择()1.Peter _ a boys name.AisBareCbe Dam()2.Where _ her rulers?They _ on the desk over there.
