Perhaps some can hack(应对) it for about two or three years and then they want to either go back home or move on to another country. As for me, I cannot get 36 of this place. I love it here so much and I honestly believe that I am very comfortable here. It feels just like 37. And, here 38 the story.

When I arrived in LA I was very excited and a little 43 because I didn't know what to 44 when I arrived in China. It 45 like receiving a wrapped gift and you had no idea what was in it 46 you opened it. As I 47 the Korean Airlines 48 desk I gave the attendant(空乘人员) my ticket. He looked at me and said, "I'm sorry, sir. This flight was yesterday." I was in 49 and lost for words. The attendant told me I had to wait several hours until they could 50 whether I could get onto another flight.
I was so afraid at this time that I called my mother and frantically(狂乱地) told her," I missed my flight! I don't think I can go to 51! I'm better off going back to Washington, DC!"

Looking 53 all of the papers I found a phone number and called the Beijing office. 54, my leader was there and assured me I could still join the group. Also, KAL had a seat for me on the next flight. So, after 24 hours and a 55 in Korea, I arrived in Beijing. I don't know what my feeling was, but I wasn't tired because I had finally arrived and I just wanted to look around the city. As I traveled to the hotel in the car I saw all the wonderful buildings, friendly people and interesting sites. I was so happy to be here.
