Why do we count things in group of ten? The reason is that we have ten fingers. Long 41 , when people had to count a lot of things, they matched them against their 42 . First they counted out enough objects to match the fingers of 43 and then put them away in one group. 44 there were more than ten, they formed more groups. We can call our number “two-handed numbers, because they developed from the 45hat people counted things on two hands. Some people had “ 46 numbers , too. Because there are five fingers on one hand, they counted things out in groups of five. It was 47 by Romans who lived in Italy over 2000 years ago. We call their written numbers Roman numerals and we use them even today. In Roman numerals, “I stands for one, and “V stands for five. For six, the Romans wrote “VI . 48 people counted objects in groups of 12. We 49 use the 12-in-one-group system for telling time with a clock.

Now satellites are helping to forecast(预报)the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, because this is where the weather forms. They send these pictures to the weather stations. So meteorologists(气象学家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead.

Nearly all our food comes from the soil(土地). Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter(粪)from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers(化肥)are also very useful. The same crop(庄稼)should not be grown in the same place every year, it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.

Why do we come to school? Most of us may say we come to school to study. But to study needs a right way, or you either waste the time or the money. The following are the ways for studying.
The best time for reading is morning. In the morning the air is fresh and the mind is clear. For that reason we can get good results.
In studying we must have patience(耐心). If we have not known a text well, we must read it again. We should not read the next one until we have learned the first one well.
When we are studying, we must put our hearts into the books, or we can get nothing from the books while we are reading.
We must always ask “whys”. If it is not well understood, write it down and ask our teachers or our parents, brothers or friends. In any possible way, we must know it completely and what we have learned can be used well and made better.
Though there are many ways for studying, yet what I have said above will be enough if we can keep them in heart and do so.
