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 30、Hi, dear boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.
First, eat different foods, especially fruit and vegetables. You may have a favourite food, but you'd better eat something different, if you eat different foods, you will probably get more nutrients (营养物质) your body needs.
Second, drink water and milk as often as possible. When you're really thirsty, cold water is the No. l choice. Milk is a great drink that can give you more calcium (钙) your body needs to grow strong bones.
Third, listen to your body. How do you feel when you are full? When you are eating, notice how your body feels and when your stomach feels comfortably full. Eating too much will not make you feel comfortable and make you fat.
Fourth, limit screen time. Screen time is the time you watch TV, DVDs and videos, or using computers. It is good to take more exercise such as basketball, bike riding and swimming. You can't watch TV for more than two hours a day.
Fifth, be active. One thing you'd like to do as a kid is to find out which activity you like best. Find ways to be active every day.
Follow these rules and you can be a healthy kid.统考英语阅读理解 随着测量次数的增加，随机误差符合一定的统计规律，绝大多数随机误差符合 机电一体化概论 数量短语作补语的是（） 当代语法学研究
