［析］ What can I do for you? 这一问语实际上用于的情景很多，要根据具体情况而定。如在商店中售货员讲这句话应译为：您想要点什么?在其他场合也可以被译为：我能为您做些什么?它的答语应是直接讲出想让对方提供的帮助。
［误］ - Which colour do you like?
- Sorry， I don't like
［正］ - Which colour do you like?
- I prefer blue
［析］由 which 来提问的问句是要回答具体的选择，而不能泛指，泛泛的回答。如 Yes， I like it
［误］ Do you like to come with us tonight?
［正］ Would you like to come with us tonight?
