车上遇见外国人，高中生的我想和他聊天练习英语口语，一开始该说什么内容（英语回答）？

那还不容易？

hi, i just want to speak to you, see if i can understand your english or you can understand mine

hi, i'm a high school student trying to see if my english works

hello, i'm a local, presently learning english, can u understand our china's english ?

u must be tourist, right ? are u facing any difficulty using english here ?

oh. are u eropean or american ? do u find any accent in our spoken english ?

说到完 一句话 ， 开口去说 就是了

Where do you want to visit in Beijing?

the Forbidden City? or the Summer Palace?

oh ,have you ever been to Great Wall?

There might be a saying you have heard>“不到长城非好汉”之类的……

也可以讨论讨论他想要去购物的地方，提一些建议，，比如不要被别人宰之类的，，最好带些中国朋友
最后用“Have a good trip in China”结尾

祝你成功

hello I‘m XX I’m a chinese senier student ！ and nice to meet you ！ I want to be your friend！aha ... 然后问他一些关于兴趣的话题！ 把话匣打开！ what do you like ！之类的 水平有限！呵呵 建议去英语网站上搜一些话题！

问问天气把~我上次就是这么问的，然后就说到武汉的天气`最后就聊开到各种小吃之类的，呵呵 很能扯把~自然点 外国人也是普通人哪~

嗯，当然是天气，还有一些又好回答，又不会涉及别人隐私还有政治的。
举个例子： Do you like living in China? How do you like Chinese food? What do you think of the Olympics?
