单选题 We were late as usual. My husband had insisted on watering the flowers in the garden by himself, and when he discovered that he couldn't manage, he asked me for help at the last moment. So now we had an hour to get to the airport. Luckily, there were not many cars or buses on the road and we were able to get there just in time. We checked in and went straight to a big hall to wait for flight to be called. We waited and waited, but no announcement was made. We asked for information and the girl there told us that the plane hadn't even arrived yet. In tile end, there was another announcement telling us that passengers waiting for Flight LJ108 could get a free meal voucher(凭单) and that the plane hadn't left Spain for technical problems. We thought that meant that it wasn't safe for the plane to fly. We waited again for a long time until late evening when we were asked to report again. This time we were given vouchers to spend the night in a nearby hotel. The next morning after a bad night because of all the planes taking off and landing, we were reported back to the airport. Guess what had happened while we were asleep! Our plane had arrived and taken off again. All the other passengers had been forgotten. You can imagine how we felt!
