Mountains are usually not nice places for people to live in, mainly because the weather in high mountains is not as good as that in lower lands. Only a few people live in the mountains that are over 2, 500 metres high. 1 If a mountain is higher than 8, 000 metres, like Qomolangma, there is not enough air to support human life. 2 Besides, there is less ground to grow plants, and plant growing is not often successful because of the bad condition.
However, mountains are important to people. As we all know that most water in the rivers is from the snow and rain water of the mountains. More than half of the people in the world depend on mountains to get drinking water. Mountains are also rich in minerals (矿产). 3 More recently, a lot of national parks and ski fields are built in mountain areas. More people go to the mountains to spend their holidays during the hot weather, because it is cooler in the mountains.
4 The sport first became popular in England and soon all over the world. However, only a few people reached the tops of the highest mountains at that time. 5

Ⅶ. 阅读与回答问题
根据短文内容，回答下列问题(每题答案不超过6个词)。
American Grace Brown is keeping busy during her first year of high school. She studies all subjects, such as English, History and Maths, as well as taking classes in Latin. She also sings in a school team and plays the piano. The school day lasts from about eight o’clock in the morning to three in the afternoon. But because of her many activities, Grace has no time for a class in physical education. So she is getting school credits (学分) for virtual (虚拟的) PE.
The idea, as strange as it may sound, depends on wearable health recording devices (设备). Brown wears a health tracker (追踪器) called Fitbit that the school provides. She wears it on her arm while doing exercise lasting 30 minutes or longer three times a week. She usually does this outside of school hours. Her computer has a programme that records her activities which she can provide for school for credits.
A PE teacher may not guide the Fitbit - wearing students in person. But teachers do guide students’ work by setting goals such as fat burning, using the technology as their eyes and ears. Grace Brown has been adding light running and bicycle rides to her days. For students, it is a welcome way to take a required class (必修课) that some students may find socially or physically difficult. Grace’s mother Rhonda Brown says, “These kids are burning 2, 000 calories during a practice and more at every game. I wish the schools would catch up with the times.”
However, technology and the collection of any student’s data (数据) always cause worries about students’ personal information. And some Americans worry that students exercising on their own may miss out on important social spirits such as teamwork.
