47、Mr Brown was very good at fixing things around the house when they broke. One day he went to another city to do some work there, and his wife was alone in the house. While Mr Brown was away, one of the faucets（自来水龙头） on the bathtub broke. Mrs Brown didn't know much about fixing broken faucets, so she telephoned a plumber（管子工）. The plumber came to the house that afternoon and fixed the faucet in a few minutes. When he finished, he gave Mrs Brown his bill for the work. She looked at it for several seconds and then said, "Your prices are very high, aren't they? Do you know, the doctor costs less than this when he comes to the house?" "Yes, I know," answered the plumber, "I know that very well, because I was a doctor until I was lucky enough to find this job a few months ago."统考英语阅读理解

17、Tibet is among the most popular places for Chinese tourists. The number of travelers to Tibet has grown by 10% every year for a few years. Since July 1, 2006, when the first train ran 1956 kilometers from Xining to Lhasa, more and more people have been to Tibet. The train stops at several famous places along the way, such as Qinghai Lake, Kunlun Mountain, and the Potala Palace. Passengers can also enjoy many activities during the journey, like Tibetan dancing and Karaoke. On the train, passengers can have tea, eggs and noodles for breakfast, and fried chicken and green vegetables for lunch and dinner. Unlike most Chinese trains which have open-hole toilets, this one has special toilets which can collect the waste. There is also a special rubbish system in the train that keeps the environment clean. All the windows on the train can protect people from the bright sunlight. TV and electrical sockets for computers and mobile phones are available on the train. Because there isn't much oxygen there, trains will have oxygen masks for those who need them. It makes passengers feel more comfortable when they have enough oxygen on the famous “roof of the world”. There are also doctors on the train to make sure that all of the travelers are safe.统考英语阅读理解
