These are similar requests for directions. Both are correct, but the first one sounds less polite. That is because it is a very direct question. It is not enough to just ask a question correctly. We also need to learn how to be polite 68.当我们请求帮助时。

69.Usually polite questions are longer. They include expressions such as " Could you please?" or " May I ask ?" It sounds more polite to say, " Peter, could you please tell me your e-mail address?" than " Peter, tell me your e-mail address." Sometimes we even need to spend time leading into a request. For example, we might first say to a stranger, " Excuse me, I wonder if you can help me" or " I'm sorry to trouble you, but…" before asking for help.

It might seem more difficult to speak politely than directly. However, it is important to learn how to use the right language in different situations. 70.This will help you communicate better with other people.
