Be动词用法
在英语学习中,be动词一共有三个:am. Is are.(是的意思)其中am和is的过去式是was,are的过去式是were.
Eg: I am a teacher.我是一位老师。
I was a teacher.我过去是一位老师。
解析:第一个句子中“am”属于一般现在时,表示目前的状态:说明现在是一名老师。第二个句子中“was”属于一般过去时,表明过去是一位老师。
be动词记忆有诀窍:I我用am, is用于he他she她it它; you你/你们和they(他们)要用are.
单数名词全用is,复数名词都用are
Eg: They are students.他们是学生。
解析:因为主语是“They”属于复数人称代词,所以要用be动词“are”
一般疑问句中只需把be动词“am, is are”放在句首,否定句就在be动词“am,is are ”后加not.
Eg: She is a good girl.
一般疑问句:Is she a good girl?
否定句: She isn’t a good girl.
解析:一般疑问句所以把be动词“Is”提到句首,否定句,就在be动词“is”后加not,缩写形式:isn't.
