We have a terrible school trip last weekend. Some students were late. Then we waited half an hour for the school bus, but it didn’t arrive. Finally, our teacher took us to take the subway. It took us about an hour. After we got off the subway, we walked and got lost. When we finally arrived at the zoo, we were tired and hungry. We wanted to see dolphins, but there weren’t any. There were some really smart seals, but we didn’t see the show because we arrived too late. We left our camera at school, so we didn’t take any photos. Then it started to rain, and no one had an umbrella. So we went for lunch. My friends had some ice cream. But I didn’t have any, because I don’t like it. We didn’t see many animals because of the rain. Finally we went back to school. We were wet, tired and stressed out(紧张). I didn’t enjoy my school trip at all.
【小题1】Why did the students take the subway?

　　Careful and careless are as different as fire and water. But it is strange that quite a few scientists have both these qualities (品质). They are both careful and careless. Newton, the famous English scientist, was such a person.

　　Once Newton invited a friend to dinner at home. When they were ready to eat, Newton left to get a bottle of wine. But after his friend had waited for a long time, Newton still didn't come back. At last his friend found Newton was in the lab. When Newton was going to get the bottle of wine, he suddenly had a new idea for his experiment (实验) . So he forgot his friend and the dinner. Another time, Newton was leading a horse up a mountain, and held the rein (缰绳) in his hand. While he was walking, he kept thinking about problems. When he got to the top of the mountain, he found the rein was not in his hand and that the horse was missing.

　　Einstein was another example. Once he was waiting for a friend at a bridge. While waiting, he became lost in thought. It started to rain. The rain kept on for some time. When he took out a piece of paper to write something down, the paper was wet and then he knew that it was raining. But after he put the paper into his pocket, he again forgot he was standing in the rain.
