Today，we took the flight from the Washington D.C.IAD airport to Beijing. After went through the security check，I stopped in an American duty free shop to buy some toblerone chocolate，after asking the cashier for lots of times. I finally understood the meaning of buy two same products and get the third one free because the cashier was African or maybe Pakistan so there was some accent when they speak English. Then I bought a hamburger meal at a big meal restaurant. The hamburger was so big that after eating them and drank the cola，I nearly got full. I only ate about half of the chips before I left the plane the next day. On the plane，we flew about thirteen and a half hours and for about half an hour until we finally arrived safely at the airport. I was so excited.
这次美国之旅结束了，虽然有很多不舍及遗憾，但是终将结束，希望我们一直铭记那句话：世界那么大，嗯我想去看看。虽然我们不能把所有地方都看到，但是我们做好了一生来一个地方认真参观的准备。
