1--Tom, how do you think of second-hand goods?

2--Why did you ask that? Do you want to buy the used goods?

1--I'm considering buying a second-hand computer for I'm short of money now.

2--You know the car I'm driving, which is still in good condition though it is second-hand. And it only cost me 300 dollars. It was so cheap.

1--But do you really mean that the second- hand goods are just as good as the new ones?

2--It depends. So you must be careful buying second-hand goods.

2--你知道我正在开的那辆车吧，它虽然是二手货，但性能依然很好。而且只花了我300美元，真是太便宜了。

1--但是，你真的认为二手货同新的一样好吗？

2--这得看情况，所以你买二手货的时候一定要小心。
