胡子：青青，你去哪儿?

青青：我去超市买菜。

胡子：正好顺路，你搭我的顺风车吗?

青青：太好了。

胡子：请系好安全带。上次小李忘了系安全带，被警察罚了。

青青：是嘛，我不是司机，也必须系安全带吗?

胡子：对，坐在车子第一排的都必须系安全带。

青青：好吧，我系好了，出发吧。

胡子：Qing Qing, where are you going?

青青：I’m going to the supermarket for some vegetables.

胡子：It’s on my route. Would you like have a ride?

青青：That’s great!

胡子：Ok, please fasten your seat-belt. Xiao Li forgot to do that last time and was fined by the police.

青青：Really? But I’m not a driver. Do I have to fasten the seat-belt?

胡子：Yes. Those who take seats in the first row must fasten the seat-belts.

青青：All right. Done. Let’s go.
