Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.

Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of others, for example, fresh water. It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

Reading is the key to school success and, like any skill, it takes practice. A child learns to walk by practicing until he no longer has to think about how to put one foot in front of the other. An excellent sportsman practices until he can play quickly, correctly and without thinking. Educators call it “automaticity (自动性)”.

A child learns to read by sounding out the letters and finding the meaning of the words. With practice, he stumbles less and less, reading by the phrase (短语). With automaticity, he doesn’t have to think about the meaning of words, so he can give all his attention (注意) to the meaning of the text.

It can begin as early as first grade. In a recent study of children in Illinois schools, Alan Rossman of Northwestern University found that automatic readers in the first grade not only read almost three times as fast as the others, but also got better results in exams.

According to Rossman, the key to automaticity is the amount (数量) of time a child spends reading, not his IQ. Any child who spends at least 3.5 to 4 hours a week reading books, magazines or newspapers will probably reach automaticity. It can happen if a child turns off TV just one night for reading at home.

You can test yourself by reading something new which is suitable (适合) for your level. If you read aloud with expression, with a sense of the meaning of the sentences, you probably are an automatic reader. If you read brokenly, one word at a time, without expression or meaning, you need more practice.

Many people like reading books because it is a good way to pick up new vocabularies ,see grammar in action and develop your understanding of a language.

The key to success is choosing the right book for yourself.

For beginners, I would recommend starting with something short and simple. Chi­-ldren’s books are a great place to start .Dr Seuss’s books can make you laugh. Dr Seuss writes his books in rhyme(韵文)and they are all very funny—The cat in the Hat is probably his most well—known book. Starting with something like this means you are easier to finish the book and want to read more.

For more advanced learners, you could try The Hobbit by J.R.R Tolkien. The book isn’t too long and if you’ve seen the film, it may be easier to follow.

If you’re not quite ready to read a full book, why not try Roald Dahl’s Revolting Rhymes? This book contains lots of short stories, all written in rhyme. Or ,try a very short story book—like one from Roger Hargreaves’s Mr Men and Little Miss series. Although they are intended for young children, they are a good way to pick up some more basic vocabularies.

    Mr．Xu is our science teacher．He has a special way to make his classes interesting．He often teaches us how to make things like planes，boats and robots．

    Do you know what a robot is?A robot is a machine．It looks like a man and it can do different kinds of jobs．

    Look at that robot．We like it very much because it can do many things．It’s now cleaning the windows of an office building．It’s not easy for workers to do this because the building is very tall．It’s dangerous for people to do such work．

    Thanks to robots，people don’t have to do heavy or dangerous work any more．It’s really a great help to us．

We are learning English, but how can we learn English well? A student can know a lot about English, but maybe he canˈt speak English.

    If you want to know how to swim, you must get into the river. And if you want to be a football player, you must play football. So, you see, you can learn by using it. You must listen to your teacher carefully in class. You must speak English to your classmates every day and also you must write something in English. Then one day you may find your English is very good.
