You may feel curious about students in other countries: Do they also have so much homework? 61.他们在课余时间做些什么事儿呢？

On April 8, a report came out on the lives of high school students in China, Japan, South Korea and the US. It surveyed around 6,200 students from the four countries last year. You will find the answers to many of your questions in this report.

Who studies hardest?

Who sleeps most often in class?

63. Japanese students fall asleep in class most often. About 45% of them said they sometimes doze off (打瞌睡) in class. In South Korea, it’s 32%; in the US, 21%; and 5% in China.

Who is the most distracted (分心的)?

64. American students are the most active in class, but also the most distracted: 64.2% said they chat with friends in class; 46.9% said they eat snacks in class; and 38.9% said they send e-mails or read unrelated books in class.
