【合作探究】
1.熟读3a, 自主完成3a表格，同桌互查。
2.根据1a 表格完成1b，编对话，并展示。
3.探究重难点
1. — We have a lot of rules at my house.
— So do we .
So do we是一个倒装句，用so开头的倒装句所叙述的事与前面所讲的事相同。
So +be动词/助动词/情态动词+主语 ,在时态上应和前句保持一致，意为“…也是这样”例如: —Jim will go shopping. —So will I .
“So+主语+助动词” 意为“的确如此”
例如: —China has developed rapidly in the last few years. —So it has.
补充句子：—Li Ming studies very hard. —______________.(我也是)
—It was cold yesterday. —___________________. (是的)
2.Me, too. But I have to be home by 10:00pm.
have to 与 must都有“必须”之意，但用法上有区别。
1）have to 更强调客观原因，指“不得不”；must强调主观上。
e.g. My mother is calling me and I have to leave now.
2)have to 在进行句式转换时必须借助于助动词，而must直接进行自身转换即可。
e.g. Must we study hard?
e g. Does he have to go to bed at nine?
3)回答have to的句子时依然借用助动词，而回答must的句子时，肯定回答用must,否定回答用needn’t.
e.g. —Must he stay at home ? —Yes, he must./No, he needn’t.
