Key

　　Directions ： There is a passage in this section. The passage is followed by some ques- tions. For each of them there are four choices marked A ） ， B） ， C） and D ）. You should decide on the best choice.
　　As I travel across the country， I often find airline employees who go far beyond the normal in order to help confused， misled and frantic passengers. I try to take the time to write a comment to their airline on the airline's site. Though complaining is the norm， compliments are remembered far longer than complaints.
　　A few months ago， a gate agent went out of his way to help a passenger whose schedule was being destroyed by tarmac （停机坪） delays and storms. The passenger spoke no English and had already been delayed for three hours on the tarmac. Fortunately， the captain decided to return to the terminal to allow passengers to use facilities and let the storms pass.
　　The passenger in question had been seated next to me and we struck up a conver- sation. As we sat on the runway， he became more and more concerned about whether he would make his connection to Santo Domingo. Luckily， I had my iPhone and could look at schedules for him should he miss his connecting flight. He was out of luck and would not be able to make the connection and would be stuck overnight in Boston.
　　I spoke with the gate agent when our plane returned to the terminal. He checked flights and said， "I can get him on a flight to Miami and on to Santo Domingo in about an hour. "
　　"Great，" I said， "but， his luggage is aboard the plane； it was gate checked. "
　　The agent took the passenger down the jetway （飞机跑道） and had the baggage handlers pull luggage until they found his bag. Both the passenger and the gate agent came back wet， but both were happy. The passenger headed to Santo Domingo and the gate agent went back to work.
