单选题 One afternoon, two persons went to see their friend off. Since they went to the railway station early, they began to talk. They talked about lots of things, for they hadn"t been together for such a long time. And they looked very excited(激动).
Half an hour later, the train pulled into the station. But they didn"t notice the train and continued talking, as they put too much attention on their talking. At last, when the train was going to start, they looked up, took their bags and ran to the train. Two of the men got on the train, but the third one didn"t. He looked very worried because the train was going away fast. A train conductor (列车员) at the station saw all this and spoke to him. "It"s all right," the conductor said, "There will be another train this evening. You will soon be able to meet your friends again." "But the trouble is that they came to see me off," answered the man.
