打招呼的表达：四种实用常见的表达方式：
No.1 How are you doing today? I am doing great.Pretty good,not good,not bad,在how are 这两个词之间有连读现象，（不要读成号挖油X）语调降调处理，How is everything going? How is your day?
No.2 Morning!Nice your shoelaces.Nice+你要夸赞对方的话。Nice suit/haircut/purse/handbag/jacket! You look great/awesome/amazing today!
Hello there,how is everything going.hi there, how is everything going.回答的时候不加there,直接回答hello,
No.3- Hey!It’s such a lovely day,isn’t it?-Yes,I like sunny days. -Me too.I just hope that it doesn’t get rainy again. -The weather forecast says it won’t rain. 句型：it is such a+形容词+day! Sunny/windy/cloudy/rainy/snowy/hot/cold,It’s pretty +形容词+outside!
No.4补充内容：-What’s good?怎么样，有什么新鲜事吗？-What’s new? –What’s popping?Anything new? 回答-Nothing much.没什么发生。
道别的表达 ：
一、 正式场合 NO.1 Have a good day!good后还可以根据具体的情景添加合适的单词，比如weekend,vacation,night.Have a good+具体名词。 eg.今天加班到很晚，跟同事道别：Have a good night,bye!
NO.2 Take care.至少有一周不见面，更多用在非常正式的场合，这是一场非常正式、温暖、真诚的道别。Take care of+ sb. / sth.表示照顾好某人或某事。You have to take care of yourself. NO.3 I look forward to seeing you again.我很期待再次跟您见面，还想跟这个人继续做生意/保持联系，to+doing,to 在这里做介词，后面动词加ing的形式，eg.I look forward to meeting you again .I look forward to our next meeting.
二、 休闲场合 NO.1 See you later.See you.Catch you later.
NO.2 Keep in touch.这句除了表达道别外，应用到句子中表示保持联系 I keep in touch with most of my classmates.
NO.2 Gotta go. 省略主语I的口语表达方法，gotta表示必须做某事，You gotta give me some answers.gotta必须用在口语中
NO.3 Bye:不管在什么场合下用了什么样的表达，我们最后都可以使用bye来结束对话。
A:See you later.B:OK,have a good day.A:You too.Bye.B:Bye.
That’s all for today’s class.I look forward to seeing you again.Bye.
