一个简单诀窍，“助动词”无形之间让外国朋友也觉得地道

Hey, buddy, do you have a power bank please?
一般人的回答：Yes/ yeah/ yep/ yup/ ya


【做笔记】
在做肯定或否定回答时
（1）在yes/ no后面带上主语+助动词
Q: Do you walk everyday to work?
A: Yes, I do. / No, I don’t.

（2）或者只用主语+助动词，不带yes/no
Q: Are you from the famous tourism city from China?
A: I am!

（3）或者重复问句并加上助动词，特别是在肯定句中加助动词表强调
Q: Do you love your husband no matter how rich or poor he is?
A: I do love him.

Hey, buddy, do you have a power bank please?
“装逼”的回答: Yes, I do./ I do. / I do have one.
