Do you know something about tree rings(年轮)? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?

  A tree will grow well in a climate(气候)with lots of sun shines and rainfall(雨量). And little sunshine or rain fall will limit(限制)the growth of a tree. We can see the change of climate by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside, if the tenth ring is far from the eleventh ring, then we're sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.

  Tree rings are important not only for studying the history of weather but also for studying the history of man. Many centuries ago there lived a lot of people at a place in New Mexico. But now you can find only sand there -no trees and no people. What happened?

  A scientist studied the rings of dead trees there. He found that the people had to leave because they had cut down all the trees to make fires and buildings. As all the trees had gone, the people there had to move.

  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(形成). 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(比较)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 real 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 a-head.(提前).

  When we do not understand each other's language, we can talk with the help of signs.

  A Frenchman was once travelling in England. He could not speak English at all. One day he went into a restaurant(饭店)and sat down at a table. When the waiter came, he opened his month, put his fingers in it and took them out again, He wanted to say:“Bring me something to eat.”

  The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee. But the man again refused(拒绝)it. He shook(摇)his head whenever the waiter brought him something to drink, for drinks are not food.

  When the man was going away, another man came in. This man saw the waiter, and he put his hand on his stomach(胃). That was enough.
