和人搭讪怎么用英语先开口?

It\'s a sunny day,isn\'t it?
How are you doing?
Give me five.
I saw you somewhere,do I know you?

hey或hi

一定是确实有话要讲 随便搭讪 会让对方觉得奇怪

如果是一些较正式的场合,最好说Good morning!May I have your name?再自我介绍.My name is_,I am from_较熟之后,可以说What is your hobby?然后你可以聊你们共同感兴趣的话题.例如,sport,food,music,travel,etc.

Hello,can I ask you some question?
