Passage Four
Henry was worried. This was his first time to go traveling by air. He did not know how to find his seat, so he went to the airhostess (空姐) and asked ,"Could you help me I can’t find my scat. "The air hostess showed him the seat and told him to sit down and fasten the seat (系好安全带). She told Henry not to move about when the plane was going up. And she also said that Henry’s ears might feel a little strange, but he didn’t need to worry about it because many people felt like that. When the plane was flying very high, Henry could stand up and walk round. He could either read books, newspapers or see films. The airhostess would bring food and drinks. Henry, could enjoy the flight and arrive home soon.
Passage 6
A design for a remotely-controlled fire engine could make long road or rail tunnels safer. It is the brainchild of an Italian fire safety engineer, who claims that his invention--dubbed Robogat -- could have cut the death toll in the disastrous Mont Blanc tunnel fire in March 1999 which killed 41 people. Most of the people who perished dies within 15 minutes of smoke first being detected. Quick action is needed when fire breaks out in a tunnel. Robogat can travel at about 50 kilometers per hour. The Mont Blanc fire was 5 kilometers from the French end of the tunnel, so a machine could have got there in about six minutes.
The Robogat has been designed and patented by Domenico Piatti of the Naples fire department; it runs on a monorail suspended from the roof of the tunnel, when the Robogat reaches a fire, it plugs into a modified water main running along the tunnel and directs its hoses at the base of the fire. It is capable of pumping 3,000 liters
