An express train was due to go past about thirty minutes later. If it were not stopped, that long train, full of passengers, would fall into the stream. “Someone must go to the station and warn the station-master,” Kate thought. But who was to go? She would have to go herself. There was no one else. In wind and rain, she started on her difficult was. Soon she was at the bridge that crossed the Des Moines River, a bridge also built of wood, just like the bridge across Honey Creek. The storm had not washed this away, but there was no footpath across it. She would have to cross it by stepping from sleeper(枕木) to sleeper. With great care she began the dangerous crossing, sometimes on her hands and knees, hardly daring to look down between the sleepers into the wild flood waters below. If she should slip, she would fall between the sleepers, into the rapidly flowing stream. At last -she never knew how long it had taken her – she felt solid ground under her feet. But there was no time to rest. She still had to run more than half a mile and had only a few minutes left. Unless she reached the station before the express did, many, many lives would be lost. She did reach the station just as the train came into sight. Fortunately, the station-master was standing outside. “The bridge is down! Stop the train! Oh, please stop it!” Kate shouted breathlessly. The station-master went pale. He rushed into the station building and came back with a signal light. He waved the red light as the train came into the station. It was not a second too early. 21. What did Kate decide to do? A. Stop the express train. B. Check the signal light. C. Meet the passengers. D. Visit the station-master. 22. Which of the following words best describes Kate’s journey? A. Fruitless. B. Boring. C. Well-planned. D. Ricky. 23. Why did the station-master turn pale? A. He suddenly fell ill. B. He realized the danger. C. He discovered his mistake. D. He became over-excited. B The Crowne Plaza Hotel in Copenhagen is offering a free meal to man guest who is able to produce electricity for the hotel on an exercise bile linked to a generator(发电机). The idea is to get people fit and reduce their carbon footprint. Guest will have to produce at least 10 watt hours of electricity – roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meal tickets worth $36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel. The plan, a world-first, will start on 19 April and run for a year. Only guest staying at the hotel will be able to take part. Frederikke Toemmergaard, hotel spokeswoman, said, “Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don’t think people will take advantage of our programme.” Copenhagen has a long-standing cycling tradition an 36% of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen.dk. US environmental website https://www.360docs.net/doc/1d6014765.html, recently voted Copenhagen the world’s best city for cyclists. “Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as symbol of the hotel’s green profile(形象).” If successful, the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement. 24. What is the main purpose of the free meal programme? A. To promote the hotel’s green concept. B. To make the city known to the world. C. To attract people to the hotel restaurant. D. To get guests to stay longer at the hotel. 25. How can a participant get a free meal? A. By becoming a professional cyclist. B.
