18．
One morning Fan Xing discovered that her classroom had changed．The 13-year-old saw that the desks were no longer in rows（排），but pushed together to make six bigger desks．
The new arrangement（排列） was part of a reform（改革） at Fan's school，Changsha Daotian Middle School in Hunan．About five weeks ago，more than 2，000junior students at the school began studying in this way，with six to eight students sitting in groups．
"This reform is designed to provide students with easier ways to study and more chances for discussion，"said Liu Xu，a school head teacher．"Our school hopes it can improve students'abilities（能力） for self-study as well as teamwork．"
The new arrangement took some time for students to get used to．"I was too curious（好奇） about it for the first two days，"said Fan．But soon she and her classmates got used to it．"Now our class is quieter because we can stop loud students with some simple gestures（手勢(shì)），"said Fan．"What's more，we can express our own ideas and learn others'through discussion．It's a better way to study．"
Feng Yu likes this new classroom arrangement very much and has made some progress studying．The 14-year-old said，"Group members first discuss，and then explain the solutions or answers to difficult questions in front of the whole class．"
"The discussion gives us more confidence to make speeches，"said Feng．"We can also improve our friendships．"
The reform has asked for more from teachers．They have no more than 15minutes to teach in class．"It is a big challenge to teach in such short time the lessons which should be taught in 45minutes，"English teacher Wang Jing said．"We have to improve methods to teach better．We must prepare some interesting topics and exercises before class so that students can discuss them．"
Wang said that some students always talk．The teachers have to move continuously in the classroom to keep them quiet and get them to concentrate on class．"It demands more，but I believe it will pay off，"Wang added．
