日常交际用语是英语口语交流的基础，包括问候、告别、自我介绍、询问信息等最基本的表达方式。掌握这些用语可以进行简单的日常交流。
问候语：Hello! / Hi! / Good morning/afternoon/evening! / How are you? / How do you do?
回应问候：Fine, thank you. / I'm fine, thanks. / Very well, thank you. / Not bad.
告别语：Goodbye! / Bye! / Bye-bye! / See you! / See you later! / Good night!
自我介绍：My name is... / I'm... / I am... years old.
询问姓名：What's your name? / May I have your name?

询问物品：What's this/that? / What are these/those?
感谢与回应：Thank you. / Thanks. — You're welcome. / That's OK. / Not at all.
道歉与回应：Sorry. / I'm sorry. — That's OK. / That's all right. / It doesn't matter.
Good morning用于早上（上午），Good afternoon用于下午，Good evening用于晚上（见面时），Good night用于晚上（告别时）
How are you? 是熟人间的问候，How do you do? 用于初次见面
询问年龄时注意礼貌，在西方国家不要随便问女士年龄
Thank you可以说Thanks，更随意
this/that指单数，these/those指复数
What's = What is
