　　To most of us, school means classes, teachers, schedules, grades and tests．But for the children at Sudbury Valley School in Massachusetts, school is very different．

　　Firstly, there are no lessons．All the children, aged between 4 and 19, do whatever they want．There are no teachers, only “staff members”．The idea behind this is that you do not need to make children learn, because children want to learn anyway．“You do not need to say to a three-year-old, ‘Go explore your environment．’ You can’t stop them!”says Daniel Greenberg, a founder of the school．“But if you make children do what you want all day… they will lose all taste of learning．” At Sudbury Valley School, you will find children talking, reading, painting, cooking, working on computers, studying French, playing the piano, climbing trees, or just running around．Two boys spent three years just fishing!

　　The other way that Sudbury Valley School is different is that the children can decide the rules．Every week, there is a school meeting where both children and staff have one vote(投票)each－even the four-year-olds．They decide the school rules, how to spend the school money, and even which staff they want and do not want anymore．

　　When the school first opened in 1968, people said it would never work．But today, the school has 200 students, and 80％ of its students go on to college．Even the two boys who went fishing all the time have successful careers today．One of them is a musician and the other is a computer scientist．

　　If you go into the forest with friends, stay with them．If you don’t, you may get lost．If you get lost, this is what you shold do．Sit down and stay where you are．Don’t try to find your friends, let them find you．You can help them find you by staying in one place．There is another way to help your friends or other people to find you．You can shout or whistle(吹口哨)three times．Stop．Then shout or whistle three times again．Any signal(信号)given three times is a call for help．

　　Keep up shouting or whistling．Always three times together．When people hear you, they will know that you are not just making a noise for fun．They will let you know that they have heard your signal．They will give you two shouts or two whistles．When a signal is given twice, it is an answer to a call for help．

　　If you don’t think that you will get　help before night comes, try to make a little house with branches(树枝)．Make yourself a bed with leaves and grass．

　　When you need some water, you have to leave your little branch house to look for it．Don’t just walk away．Pick off small branches and drop them as you walk in order to go back again easily．When you are lost, the most important things to do is to stay in one place．
