On Tuesdays, the students can draw pictures or take photos in the beautiful garden. There is a river near the school. They can go boating or go fishing on Wednesdays. On Thursdays, they can go to the library to read newspapers. Many boys like Fridays very much, because the PE teachers will teach them to swim.

Now machines are widely used all over the world. Why are they so important to us? Because they can help us do things better and faster. A washing machine helps us wash clothes quickly. A printing machine helps print a lot of books, newspapers and other things quickly. Bicycles, cars, trains and planes are all machines. They help us travel faster than on foot. The computer is a very good machine. It was invented not too long ago. It can store information and it can do maths problems millions of times faster than a man does.
