Learning to use (3)correct language is not enough, we need to learn how to be (4)polite when we make requests. So knowing how to ask for information (5)politely is important. In English, just like in Chinese, we change the way we speak when talking with (6)different people. The(7) expressions you use might (8)depend__on whom you are speaking to or how well you know them. Usually in English (9)polite questions are longer and (10)include extra words. Sometimes we might even need to spend some time leading into a question or (11)request. It might seem that speaking (12)politely is more (13)difficult than being direct. However, doing this will also help you become better at English, or any other(14) language you wish to speak.
