Revision
1.be动词引导的一般疑问句
构成：be动词+主语+句子其他成分
如：1）He is a student.
Is he a student
2） They are students.
Are they students
3）I am a student.
Are you a student (按照逻辑关系，陈述句I am，疑问句改为第二人称)
4) 由this/that/these/those引导的肯定句和疑问句变形：
This/That is an apple.
Is this/that an apple
These/Those are apples.
Are these/those apples
Be动词引导的一般疑问句构成法则：
1.一提:be动词提到句首
2.二变：大小写、人称
3.三问号:句子末尾加问号
be的用法口诀：
我用am,你用are，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
be动词引导的一般疑问句的回答：
肯定回答：Yes,主语+be(am/is/are)
注意：简略回答不用缩写
否定回答：No,主语+be(am/is/are)+not
注意：简略回答必须用缩写。主语是I时用I’m not
