Unit 3 Could you please clean your room? Ⅰ. Revision(复习) Ⅱ. Presentation(重点，难点，考点，热点呈现) 1. Could you please +动词原形? 你能……吗？ Could在句子开头，不表示过去时态而表示请求，以表示礼貌、委婉或不确定的语气，而can则不具备这些语气，这种情况下不能把could看作can的过去式。肯定回答可以用Sure./ Of course./ Certainly./ Go ahead, please.或That’s OK/all right.，也可以用“主语+can”不能用“主语+could”。否定回答用“Sorry, +理由”，“主语+can’t/ mustn’t.”，不用“主语+couldn’t”。 表请求的结构还有：Would you please+V原？ Would you mind+V-ing？ 2.take out带出去；取出，拿出 take the rubbish out take out 100yuan take your tickets out 3. make the/ one’s bed整理床铺，make the table收拾桌子，摆放碗筷 4.

A 实意动词as+副词as B. 12. neither did I.是“Neither +be动词/助动词/情态动词+主语.”结构，表示前者的否定情况也适用于后者。 —I don’t agree with their plan. —Neither do I. —They can’t swim across the river. —Neither can we. Neither还表示“两者的否定”，即可以看成是both“两者都”的完全否定。 Both of my parents are mountain climbers.
