When you get up in the morning, do you find it hard to choose what clothes to wear? If so, you probably need help to make the bigger choices in your life, like what to do when you’re older. Brave New Girls, by American author Jean Gade-berg, will help you make such choices. It says you must be a brave new girl. A brave new girl is one who is confident, healthy and happy. A brave new girl can realize her dreams. To be brave, you need to make a decision for yourself. Other people may tell you what to do, but you should not listen to them. You must only do what you want. If you always wear clothes like your favourite TV star, you must stop doing so. Instead, become your own star and wear the clothes you want. You have to like your body, it says. If you don’t, you will not take good care of it, and it won’t stay healthy. The book also says that girls must start becoming more confident. If you are confident, you’ll succeed in life. A good way to become confident is to realize that you are as clever as boys. In fact you are. Just look at their grades! Only then can you realize your dreams and become who you want to be.

Take a class at Dulangkou School, and you’ll see lots of things different from other schools, You can see the desks are not in rows（排）and students sit in groups. They put their desks together so they’re facing each other. How can they see the blackboard? There are three blackboards on the three walls of the classroom!
The school calls the new way of learning “Tuantuanzuo”, meaning sitting in groups. Wei Liying, a Junior 3 teacher, said it was to give students more chances to communicate.
Each group has five or six students, according to Wei, and they play different roles（角色）.There is a team leader who takes care of the whole group. There is a “study leader”who makes sure that everyone finishes their homework. And there is a discipline（纪律）leader who makes sure that nobody chats in class.
Wang Lin is a team leader. The 15-year-old said that having to deal with so many things was tiring.
“I just looked after my own business before,”said Wang. “But now I have to think about my five group members.”
But Wang has got used to it and can see the benefits（好处）now.
“I used to speak too little. But being a team leader means you have to talk a lot. You could even call me an excellent speaker today.”
Zhang Qi, 16, was weak in English. She used to get about 70 in English tests. But in a recent test, Zhang got a grade of more than 80.
“I rarely（很少） asked others when I had problems with my English tests. But now I can ask the team leader or study leader. They are really helpful.”
