上海市培佳双语学校2023-2024学年八年级上学期10月阶段测英语试题
Liu Yaxuan is totally a homebody. Every weekend, this 14-year-old student from Tsinghua High School watches popular TV dramas 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 2013 survey of kids aged 2 to 14 showed about half of them spend less than one hour doing outdoor activities every day.
To some extent, heavy academic pressure (学业压力) caused this situation. Hu Huilan, 12, from Shenzhen Nanshan Language School, is busy with piles of homework and extra 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 Yidi, 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 hang out in smoggy weather,"she said.
But this causes bad health conditions. Chinese teenagers' physical conditions have been dropping for about 28 years, reported a newspaper last year.
The situation for teenagers should be changed. They should 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 them to do that. It helps them stay energetic.
