一、含有be动词的一般疑问句
(1)一般疑问句的概念：能用yes或 no回答的问句
就叫一般疑问句。
(2)含有be动词的陈述句变一般疑问句的方法：
※将be动词提至句首。
※将句末标点改为问号。
※将第一人称变为第二人称，即 I 由 you替换;
my 由 your 替换；相应地 am 也变为 are。
归纳总结：一提二变三替换。
Language points
(3)否定回答：No, 主语+ be(am, is, are)+not. 其
中 be可以与 not 缩写，但 am不能与 not 缩写。
如：—Is this an ID card —Yes, it is.
—Are you Mr. Smith —No, I’m not.
(4)一般疑问句的语调：读一般疑问句用升调 ↑，
其简略回答用降调 ↓。
【特别注意】
　　疑问句的主语是第一人称, 回答时主语要换成第二人称; 疑问句的主语是第二人称，回答时主语要换成第一人称； 疑问句是第三人称，回答时主语不变。
—Am I right 我是对的吗
—Yes, you are. 是的，你是对的。
/No, you aren’t. 不，你不对。
—Are you Alan 你是艾伦吗
—Yes, I am. 是的，我是。
/No, I’m not. 不, 我不是。
