五、阅读理解
Students have 10-minute breaks between classes. They can do some exercise, talk with each other and relax during the time. However, to keep students safe, some schools stop their students from leaving classroom during breaks—unless (除非) they need to go to the bathroom.
Ding Ding is a student from a middle school in Beijing. He and his classmates can go out to the bathroom, get a drink of water, or play in the classroom if they don't run or shout during breaks. "School life has become really hard," Ding Ding says. "Sometimes we even don't have time to go to the bathroom."
Since ten years ago, the Ministry of Education (教育部) has asked schools to make sure students have 10-minute breaks between classes. Besides that, schools should also make sure students have a 30-minute break each day for exercise.
It's important for students to take a rest between classes. This can help them relax, keep healthy and avoid myopia (避免近视), says an officer from the ministry.
Many schools in Shanghai and the cities of Shenzhen and Guangzhou have provided (提供) colorful activities for students to fully relax during the 10-minute break. Some schools have even extended (延长) the breaks to 20 minutes.
In Shenzhen, many schools are providing outdoor games and reading corners during breaks. A school even sets up two almost three-storey-high slides (滑梯) to let students get to the playground faster during breaks. And many other schools around the country will follow them in the future.
