Common English Greetings and Expressions
1. Hey, Hey man, or Hi
You can use “hey“ and “hi“ to greet someone instead of “hello“. Both are particularly popular among younger people. While “hi“ is appropriate to use in any casual situation, “hey“ is for people who have already met.
除了“hello“，打招呼还可以说“hey“ 和 “hi“，年轻人用的比较多。“hey“一般不用于跟陌生人对话，一般是认识的人才会说hey。
2. How’s it going? or How are you doing?
These are casual ways of asking “how are you?“ If you’re trying to be particularly polite, stick with “how are you?“ but otherwise, you can use these expressions to greet almost anyone. You can answer with “it’s going well“ or “I’m doing well“ depending on the question.
相比于“how are you?“ ，这两种表达要更随意一些，如果你想显得礼貌一点，就直接说 “how are you?“，其他情况都可以用这两种表达。你可以回答“it’s going well“ 或者“I’m doing well“，看具体情况。
3. What’s up?, What’s new?, or What’s going on?
These are some other informal ways of asking “how are you?“ which are typically used to casually greet someone you have met before. Most people answer with “nothing“ or “not much“.
这两种是更不正式的打招呼方式，一般来说是对你认识的人说的，你可以回答“nothing“ 或者 “not much“（没什么/就那样）。
4. How’s everything ?, How are things?, or How’s life?
These are some other common ways of asking “how are you?“ They can be used to casually greet anyone, but most often they’re used to greet someone you already know. To these, you can answer “good“ or “not bad“.
也是常见的 “how are you?“ 的替代，也比较随意。回答可以是 “good“ 或者 “not bad“（还不错）
5. How’s your day? or How’s your day going?
These questions mean “how are you?“ not just right now, but how you’ve been all day. You would use these greetings later in the day and with someone you see regularly. Many people simply answer with “fine“, “good“ or “alright“.
这几个问题一般问的不是你现在的状态，而是你的一天怎么样。很多人会简单回答说 “fine“, “good“ 或者 “alright“。
6. Good to see you or Nice to see you
These casual greetings are used with friends, co-workers or family members that you haven’t seen in a while.
7. Long time no see or It’s been a while
These casual greetings are used when you haven’t seen someone in a long time, particularly if you meet that person unexpectedly. Usually, these phrases are followed with a question like “how are you“, “how have you been?“ or “what’s new?“
这个短语一般用于很久没有见的人，尤其是偶遇某人的时候。通常说完这句话之后，就会说“how are you“, “how have you been?“ 或者 “what’s new?“。
Business Greetings and Formal Greetings
8. Good morning, Good afternoon, or Good evening
Keep in mind that “good night“ is only used to say “good bye“, so if you meet someone late in the day, remember to greet them with “good evening“, rather than “good night“.
注意，good night（晚安）只用于道别的时候，所以如果你在晚上遇见别人，记得说“good evening“（晚上好）而不是“good night“。
9. It’s nice to meet you or Pleased to meet you
These greetings are formal and polite. If you say this to someone when you meet him or her for the first time, it will make you seem courteous.
10.How have you been?
This greeting question is only asked by people who have already met. If someone asks you “how have you been?“ they want to know if you have been well since the last time the two of you met.
11. How do you do?
This greeting is VERY formal, and quite uncommon, but it may still be used by some older people. The proper response is “I’m doing well“ or, as strange as it seems, some people even ask “how do you do?“ right back as an answer.
这个表达非常非常正式，而且很不常见，但还是有些老人会用。正确的回答应该是“I’m doing well“或者 “how do you do?“（对，你没有看错）。
Slang English Greetings
This extremely informal greeting is common in America. It comes from 1990’s hip-hop slang and these days it’s often used jokingly. This greeting should only be used with very close friends, and never in a business setting.
13. Are you OK?, You alright?, or Alright mate?
This casual way of asking both “hello“ and “how are you“ is common in Britain. You can respond “yeah, fine“, or simply “alright“.
这几种表达在英国用的比较多，你可以回答 “yeah, fine“, 或者 “alright“（我很好）。
This is a very informal abbreviation of “how do you do?“ that is common in certain parts of Canada and the U.S. Keep in mind that if you say “howdy“ outside of these regions, you will sound like a cowboy, and it might make the other person laugh.
这是“how do you do?“ 的缩略表达，尽在加拿大和美国的部分地区有用。在其他地方，这个表达听起来比较粗鲁，可能还会有点搞笑。
15. Sup? or Whazzup?
These greetings are abbreviations of “what’s up?“ which are common among teenagers.
这两种是“what’s up?“ 的缩略形式，在青少年中尤为常见。
16. G’day mate!
This casual greeting is an Australian abbreviation of “good day“. Keep in mind that Australian greetings often use “ya“ instead of “you“. So “how are ya?“ is the same as “how are you?“, and “how are ya going?“ is basically the same as “how’s it going?“ or “how are you doing?“
这是澳洲英语“good day“的缩略表达，在澳大利亚，一般会把 “you“说成“ya“ 。
This greeting, short for “how are you?“, is commonly used in certain parts of England. However, you don’t need to actually answer this question – you can just say “hey!“ right back.
这个表达是“how are you?“的缩略式，尽在英格兰部分地区使用。然而，这并不是一个真的问题。你可以直接回一句 “hey!“。
