阅读下列短文, 根据短文内容从每小题所给的 A、B、C、D四个选项中选出最佳答案。Liu Yaxuan is totally a homebody. Every weekend, this14-year-old student from Tsinghua High School watches popular TV dramas like The Journey of Flower(《花千骨》) and plays with her mobile phone. She hates playing outdoor sports. "It's too tiring," she said.
She is not alone. In recent years, more and more Chinese teenagers are becoming homebodies. A survey of kids aged 2 to 14 showed about 60 percent of them spend less than one hour doing outdoor activities every day.
This problem may have to do with heavy academic pressure(学业压力). Hu Huilan, 12, from Shenzhen Nanshan Language School, is busy with much homework and many after- school classes on weekends. "I don't want to get behind, " she said.
Even if this isn't a problem, kids still prefer indoor life. Wang Di, 12, from Anhui No. 50 Middle School, often reads Harry Potter, listens to music and surfs the Internet at home. "I can do so many things I like at home rather than hanging out in smoggy weather, " she said.
The situation for foreign students is quite different. Tina Smith, 15, from a high school in Toronto Canada, says her peers(同龄人) don't like staying indoors at all. " They spend their free time outdoors even if it just means going to the park or reading a book under the tree. Nice weather, little homework and rich outdoor activities enable us to do that, " she said.
