as part of the timetable. With his drawing in his hand，twelve-year-old Zhang Wenpeng said that people must wake up to? the fact that pollution is causing damage to the progress we've made.
“To save water is to save lives，” he said.
His classmate from the same primary school in the hilly countryside of western China, eleven-year-old Zhou Zhiyun, has painted a big shining light, with the message that people must not waste electricity.
The students were members of a project to discuss “changes in the climate all over the world and what we can do about them”． The school suggested that the students should pass on what they have learnt in school to their parents and neighbours.
“I told my family why we should turn off the light when we leave a room，” said one student.
China now has many green schools like this one.
In order to become a “green school”， a school must include education about the environment as part of the timetable.
“Education is important and can help children and young people change their habits.At the same time, they can pass on knowledge to their neighbours，” said a director of the Ministry of Environmental Protection.知识点2wake up to意识到；认识到辨析wake up与wake up toeg：He hasn't yet woken up to the seriousness of the situation.

Jane takes groups of people walking in the countryside.
Jane, lots of people listening are interested in walking in
the countryside. What advice can you give them about
taking people for a walk?
Jane: Well, the first thing you have to do is to plan the walk
carefully. You should think about where you are going to
walk and whether there are clearly marked paths. You
should only take marked paths. Farmers don’t like people
walking off paths because they might make the animals
afraid or cause other problems. 魔法记忆Interviewer: What about timing your walk?
Jane: Yes, that’s something you must do too. People can’t walk a
long way without food and water! Make sure you know
where you can stop for lunch, maybe a picnic area or
somewhere like that. It must be somewhere you can stay
out of the rain. Don’t forget to tell people to bring food for
the picnic. Don’t walk when it’s too hot or in very bad
weather. It’s also important that you know where you’re
going if you’re the leader of the group. You mustn’t try
out a new walk with a group. You have to know every
step of the way yourself first.Around the worldEcotourism
