语法-be动词（讲义）通用版英语六年级下册

小升初语法-be动词练习 1． 动词be的一般现在时有三种形式: _____ _____ _____ 一般过去时中，be动词的形式有：__________ 、__________。 口诀: 我(I)用_____, 你(you)用_____, is 跟着他( ) ,她( ) ,它( ), 单数 is, 复数are,勿忘be的三变化 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。  用法总结：1.如果主语是第一人称I（我）时，be动词用am。    I am a student. 我是一名学生。  I am 还可缩写成I'm。 I'm David. 我是大卫。  am 与 not 不能缩写。 I am not David.  句中含有be动词的陈述句变一般疑问句。 把be动词提到句首，be动词首字母要变大写。注意第一人称变第二人称。回答时用yes或no表示。 —Are you in Grade 7? 你在七年级吗？ —Yes, I am. 是的，我是。 在肯定答句中，主语和动词be不能缩写。 Yes, he is. 不可缩略为Yes, he's. 二．用恰当的be动词填空。 1.
