You are playing computer games. We are singing and dancing. They are running. 通过句子，教师给学生总结出动词加-ing的规则。末尾有不发音?e?的去掉?e?加-ing，以辅音字母结尾的重音在第一个音节上的单音节单词要双写末尾的辅音字母，再加-ing. 其它的就可以直接加-ing。
3.小结:
本课我们学习了向别人转接电话的常用语，以及现在进行时态的含义，结构，正确用法。还有动词加-ing的规则。
4.巩固活动:
1）4人一组，教师将学生分成若干组，要求学生在规定时间内自编对话，以给别人转接电话的内容为主，在班里展示。
2）教师将全班分成男女两组，快速出示以前所学的动词短语，要求学生也能快速将短语变成动词现在分词，说出正确的句子，巩固练习。 3)教师最后播放录音，学生听，并且跟读。 4) Let’s practise(1)
A: In this practice, we should know the meanings of several words and phrases. ‘Just a moment, in, that’s OK.’ Here when we have to hold the telephone, we can see ‘wait a moment.’ So ‘just a moment’ equals to ‘wait a moment.’ The adverb ‘in’ means ‘at home’. So here we can use ‘She’s out‘or ’She went out.’ ‘That’s OK’ means ‘It doesn’t matter’. 做这道题时，我们首先要明白很多单词和短语的含义。‘Just a moment’,相当于‘wait a moment.’ ‘ not in’相当于out，‘That’s OK’相当于‘It doesn’t matter’ 5) Let’s practise(2)
A: In this exercise, firstly when should be clear about the content of the telephone message. We know this message is from Jack to Linda at half past ten on June 21st. Jack wants Linda to do some shopping with him that afternoon. He need Linda to call back.
做这道题时，我们首先要很清楚电话的内容。例如电话是7月21日10点半Jack打给Linda的。他想邀请Linda那天下午和他一起去购物。他要求Linda给他回电话。 Kate: Hello?
Jack: Hello! Is Linda there?
Kate: No, this is Kate. Just a moment. Sorry, she’s out.
Jack: Oh. I want to go shopping with her this afternoon. Could you ask her to call me back when she comes back? Kate: OK. No problem. Jack: Thanks.
Kate: You’re welcome.
