阅读理解。 Tibet is among the most popular places for Chinese tourists. The number of travelers to Tibet has grown by 10 percent every year for a few years. What is the best way to go to Tibet for tourist trip, by plane, by bus or by train? People who want to go to Tibet always ask this question. If you take the plane, you won't see the beautiful places on the way. If you take the bus, you will be very tired after the trip. If you take the train, you can enjoy the scenery along the way and sleep quite well. Now, since July 1, when the first train ran 1,956 kilometers from Xining to Lhasa, more and more people have been going to Tibet. The train stops at several famous places along the way, such as Qinghai Lake, Kunlun Mountain, and the Potala Palace. Passengers can enjoy many activities during the journey, like the Tibetan dancing and Karaoke. On the train, passengers can have tea, eggs and noodles for breakfast, and fried green vegetables and chicken for lunch. Unlike most Chinese trains which have open-hole toilets, this one has special toilets which can collect the waste. There is also a special garbage system in the train that keeps the environment clean. All the windows on the train can protect people from the bright sunlight. Other equipment, such as televisions and electrical sockets for computers and cell phones, can also be found on the train. Because there isn't much oxygen there, trains will have oxygen masks for those who need them. It makes the 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. 1.
