1. Do you need help with something?=May I help you?/Any help? 都是询问需要什么帮助的常用语。

2. That's a wonderful choice. 一个不错的选择。在夸赞别人的品味不错的时候，可以说句：Really a wonderful choice.

3. It's very inexpensive. 这句等同于It's cheap. 但是表达得更加委婉，不是很贵这个说法能让购买者更加信服，因为冰箱毕竟是家电的大件，便宜不太可能，但是比起同类产品，不是很贵。这种表达值得借鉴。

4. purchase 购买东西，比buy更正式，buy相对地比较随意，买的东西多是小的物件。
