  We all need a healthy environment, but we produce waste every day and it does harm to our environment.Though we are young, we can still do something to help.In fact, even the simplest everyday activities can make a real difference to the environment.Here are some ideas for you to live green life.

  Remember these three words:reduce, reuse and recycle.

  Reduce means "use less".Don't waste things.This saves money and reduces pollution and waste going into the environment.Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

  Reuse means "use again".Use things for as long as possible.When we buy things, make sure that they last a long time.We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones.Don't use a paper cup or a paper bag.It's better to use a china cup and a lunch box because you can use them again.

  Recycle means "change things into something else".Although it takes energy to change something into something else, it's better than throwing things away or burning them.Find out what can be recycled in your neighbourhood and take part in recycling programmes.We should also buy products made from recycled materials, such as recycled paper, to help save trees.

  American schools are quite different from those in China.In America, at the beginning of the term, students must select their courses and teachers first.While in China students usually have no chances to select their courses and teachers.

  Selecting is very important for your grades in America.So at the first term, don’t select too many courses, 4.or you’ll feel very nervous and it may influence your study.Then you have to ask for some teaching plans.There is some information about subjects, time arranging, marks and textbooks.At the same time, you must choose the teachers.Different teachers have different teaching methods.If the teacher is called “killer” by the last grade, many students will give up choosing him.Because this kind of teacher will leave too much homework, too many exams and give too low grades.

  There is another thing after you select the course and the teacher.How to buy textbooks makes each student feel hard.The textbooks in America are very expensive.Each copy is about $30~50.In order to save money, many students buy some used textbooks, and some students usually borrow textbooks from the school library.You must get enough ready before class.In class, discussing is very important.5.老师鼓励你提出问题或展示你自己的观点。They don’t usually ask you to sit well.Instead they allow you to sit or stand everywhere you like.They don’t give you much homework to do.You can learn some knowledge and do exercises by yourself.So in American schools, you must do almost all things yourself.
