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 (大气), 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 (提前).

On a hot July afternoon, my mother and I were walking back home from a pizza store. We had bought many things. I was feeling really tired as I was carrying our shopping bag. I decided to throw something away. I was walking towards a dustbin(垃圾箱) when I noticed a poor man walking out of the restaurant in front of us. He walked to the nearby dustbin and started looking through it.

I suddenly felt very sorry because I was going to throw away a new drink just because it was too heavy. I walked up to him and gave the drink and some bread to him, which surprised him. The man looked at me in surprise and took what I gave him. A big smile appeared on his face. I felt I couldn`t be happier with myself. But then he said.”Wow, this is my son’s lucky day!”

With that, he thanked me happily and started off on his bike. I even heard him singing as he rode away. I got a warm feeling inside. I now understand what it means by the saying ”Giving in getting.”

Though it was only a little action, I got and learned more in those two minutes than I did in the rest of the month. Everyone in the world needs help. Everyone can give help and everyone can be helped.

The look of the man`s happiness appears in my mind whenever I have the chance to do something nice.
