A: I’ve had so many problems with my new car. It’s driving me crazy. 我的新车出了很多问题，我要疯了。（note: 车出了很多问题，在我们的思维中主语是车，因此通常会说my car has many problems，当然这没有问题，但要注意到，还可用别的词来做主语，比如I, I have many problems with my car, 再比如there be, There are many problems with my car.）
B: Are you sure you don’t want to buy a new one? 你确定不要买一个新的吗?
A: How can I? I already spent a lot of money on this one. 我怎么可以?我已经在这上面花了很多钱了。(note: how can I 可以连读how ca ni)
B: I guess you’ll be spending a lot of money on repairs then. 我想你在修理上要花很多钱。(note: 我们习惯把then放在句子开头说话，也可以放在句尾。)
A: I guess so. Unless, you want to buy the car. 我想是的。除非，你想买这辆车。（note: I guess替代I think）
B: No, thanks. I don’t think I’d want to buy your car. It has too many problems. 谢谢。我想我不会买你的车。它有太多的问题。（note: no thanks经常连用，拒绝别人也要拒绝的礼貌）
