Excuse me,can Iask you a question打扰一下我能问你一个问题吗?
如果不是在街上随机采访把前面的半句换成hello,thank you for your coming感谢你的到来
简单的致谢: Thank you for speaking with me/us today.
寒暄问候:How are you doing today?
结尾:
过度到结尾,让被采访者知道你已经问完了所有的问题: I have asked all questions on my list.
让被采访者补充他/她想说的,但是你还没有问到的。比如:Besides what we have discussed, is there anything else you want to share with us?
