Unit 3 Pardon Me! Lesson 17 Do Mistakes Matter? Think about it! Have you ever paid too much for something? Do you often bargain when you buy something? How do you bargain(讨价还价)? Read carefully and answer the following questions: What did Li Ming buy for Bruce? Why did Bruce look confused? Why did Bruce pay more for two pops than Li Ming? Where were they now? And why do you think so? People don’t try to change their prices(还价) in North America, do they? What about in Australia? Language notes: 1. They saw a man who’s selling pop. who’s selling pop 定语从句 先行词是a man 连接代词是who, who只能代替人 would like sth. = want sth. would like to do sth. = want to do sth. would like sb. to do sth. = want sb. to do sth. 2. Would you like one too, Bruce? 我生日的时候想要辆自行车。 你想和我去购物吗？ 他们想让你和他们一起去打篮球。 I would like a bike for my birthday. Would you like to go shopping with me? They’d like you to play basketball with them.
