Computers are useful machines. They can help people a lot in their daily lives. For example, they can help people to save much time, and they can help people to work out many problems they can’t solve easily. Our country encourages everyone to use computers, except the old people.
Today more and more families own computers. Parents buy computers for their children. They hope computers can help them improve their studies in school. Yet, many of their children use computers to play games, watch videos, to the extent that computers can make them fall behind. So computers are locked in boxes by parents.
In some other countries, even some scientists hate computers. They say computers make millions of people lose their jobs or bring them a lot of trouble. Will computers really bring trouble to people? Or can they bring people happiness?

In your school bags, most of you may have a pencil, some kinds of pens, a ruler and some books. None of these things grow in the fields. They were all made in factories and invented by someone. They have not always been pencils and pens, rulers and books. Thousands of years ago, no one knew about these things.
Who invented them? We don’t always know. There have been thousands of inventions, large and small, in human history. Some of these inventions have changed the world, such as paper, printing and radio, and we know the inventors. But we have forgotten most of the other inventors. Who invented the clock, for example, or the lock to the door? We don’t know. There have been thousands of inventors and we should thank them for their brilliant ideas. Will you be one of them when you grow up?

A strange thing happens to nearly everybody at night.
People turn off their lights, pull up the covers, and close their eyes. Six or seven sleeping hours later, they wake up again. Strange, isn’t it?
Sleep puzzles scientists. Scientists and doctors would rather talk about why one cannot fall asleep. They are not sure what causes sleep.
The best conditions for sleep, they say, are good health and a meal neither too big nor too small. No worries and a comfortable place to sleep are important, too. They advise against two in one bed.
Strange things happen during sleep. For example, you often move. You would feel tired if you didn’t. You also dream. Part of your brain is still awake when you are dreaming. Memory and imagination often appear in your dreams.
Don’t worry if you dream. Some great stories and poems were begun while the writers were asleep.

A very simple experiment can be done to show that water expands when it is frozen. All you need is an empty glass jar and some clean water. First, fill half of the jar with water. Then mark the water level outside the jar. After that, put the jar in a freezer until the water freezes. When the water is frozen, take the jar out of the freezer and observe the water level and mark the new water level. You will see that the level of the frozen water is higher. This experiment proves that water expands when it is frozen.
