Allan was worried. This was his first time to go travelling1. He didn't know how to find his seat, 2 he went to the air hostess(空姐) and asked, “Could you help me? I can't find my seat.”The air hostess showed 3 the seat and told him 4and fasten the seat belt(安全带). She told Allan not to move about when the plane was going up. And she also said that Allan's ears might feel 5strange, but he didn't need to6it because many people felt 7that. When the plane was flying very high, Allan could stand up and walk around. He could 8read books, newspapers or see films. The air hostess would9 food and drinks to him. Allan would enjoy the flight and10home soon.
