导语:知识点名:一般将来时和一般现在时
讲义:
一般现在时
一、be动词的一般现在时
1.be动词的一般现在时常用来讨论客观存在的事实或状态,其肯定形式有am,is, are三种。其中am用于第一人称I;is用于第三人称单数形式he, she, it及其他单数名词;are用于第二人称you、复数人称we, you, they及可数名词复数或并列名词做主语时。可进行缩写。
例:I am Gina. =I'm Gina.
He is Brown. =He's Brown.
They are Jane and Linda. =They're Jane and Linda.
2. be动词的否定式是在be后面加not。(表格为一般现在时态中,be动词的否定形式)
3.be动词的一般疑问句的结构为:be(am/is/are)+主语+……?
肯定回答为:Yes, 主语+be(am/is/are).
否定回答为:No, 主语+be(am/is/are)+not.
例:-Are they your classmates?
-Yes, they are. / No, they aren't/are not.
注意:第一人称I变一般疑问句时,需转换成第二人称you。
