Do you have any online classes？It is possible（可能）to take classes at home.All you need is a computer and a headset（耳机）.
However，most students don't seem to like online classes. According to a recent survey，only 33%of the students would take such classes. Over 1，500 students from 10 cities took part in the survey（调查）.
Many students said it was hard to focus（专注）on studying while taking online classes.This was true for Lian Ruohan，15，at the Affiliated High School of Peking University."There are no classmates and no real teachers watching me.I can surf the Internet or do other things if I want to.It's harder to always stay focused，"she said.
Lian prepares a lot before taking her classes to make sure she will keep her attention. She also pushes herself to communicate with teachers.Students can come up with or answer questions while taking online classes.
Wen Jiayi，14，at Yucai Middle School Attached to Chengdu No.7 High School，thinks online interaction（互动）isn't enough."The online teachers don't really get to know me.When I don't hand in homework，all I get is a short message instead of real concern（关心），"she said.
However，online classes still have advantages."It saves time and money compared with taking offline classes. Also，if I don't understand some parts of a lesson，I can watch it over again，"Lian said.
