求 开始、结束对话的英文礼貌用语

　初会

　常见表达：How do you do?/Hello!/I'm glad to see you. /Nice to meet you.

　用法点津：a.回应时，只要重复一下对方所说的问候语即可。b.同样是初会问候语，How do you do？和I'm glad to see you.较正式，而Hello!和Nice to meet you.较随便。c. Nice to meet you.主要表示初次见面时的问候，而Nice meeting you.则是初次见面分手时的用语。

　告别

　常见表达：Good-bye!/Bye-bye!/Bye!/See you tomorrow(later, soon,at six o'clock)!Good night!/ Have a good (nice) day!

　Goodbye, Jim, and good luck！

　用法点津：a. Bye-bye.用于比较随便的场合。b. Good night./Night!只限于晚上告别或上床睡觉时使用。c. Have a nice day！限于白天告别时用(如早餐后家人互相道别)。d.回应第一组告别用语时只要重复一下那些用语即可，对See you tomorrow(later, soon, at six o'clock).的回应也可用Fine.或OK.，表示对约定时间的认可。回应第二组用语时要将语序调整一下，即Good luck to you, too. Goodbye. e.告别前通常要说一两句客套话，如：I'm afraid I must be off(going) now.长久告别时，还可同时表达希望今后多联系(Keep/Get in touch.)，要对方保重身体(Take care.)，问候对方家人(Please send my best wishes/regards to your family.)等。
