1--Hello,Miss. Where is the button that controls my seat?
2--It's on the arm rest.
1--Oh,I see. By the way, what shall I do if changes in altitude create pressure on the ears?
2--You can suck a candy or pinch your nose gently while breathing out. That shall help.
===================================
注解：
1.controls控制
2.arm rest扶手
3.altitude海拔
===================================
译文：
1--你好小姐，控制座位的按钮在什么地方？
2--在扶手上。
1--哦，我找到了。再问一下，如果我的耳朵因为海拔升高而感到有压力怎么办？
2--咀嚼一块糖或者轻轻地掐住鼻子并出气，那样会有帮助。
