1.when I took a train to BJ ,I had to pass through SH,where I would have transfer another train.Because the train from NC was delayed,I missed the 14th-shift express train to BJ.I was anxious about my delay. 2.I saw many passengers sitting here and there,tired and boring.what a pity,they hadn't catch the train too. 3.I happened to meet a friend,who was working in the train station.He consoled me that the next shift train to BJ was about to go. 4.I was happy when I was talking with him,I needed a friend to chat with then.so,I began to complain about the service in the train station
