Today more and more people are using refrigerators. Some are big, others are small. Big ones have two or three doors. Such refrigerators can not only keep the food cold and fresh, but also make ice and freeze the food. However, small ones usually have one door and can only keep things cold and fresh.
There are also refrigerators that are friendly to the environment. In the 1970s, the world was in energy crisis(危机). Refrigerators use too much energy. So people began to think of ways to improve it . At last a kind of new refrigerator was made. They use very little energy, but they’re too expensive. They cost twice or three times more than the ones that we use at home. However, people believe they will be cheaper and cheaper. As a result, they will be more and more popular.
In the future, there will be refrigerators that can do more than we can imagine. They are called smart refrigerators(智能冰箱) . They have tiny computers inside, with their screens on the door. They can show us what food is inside. They can also tell us what food to buy.They can even let us know what food to eat when we input the necessary health information. The more surprising thing is that they can do shopping for us when they are connected(连接) to the supermarket.
【小题1】Small refrigerators can not only keep the food cold but also freeze the food.
【小题2】Refrigerators that use very little energy are more expensive.
【小题3】Friendly refrigerators will be popular some day.
【小题4】Refrigerators that keep the food fresh are smart refrigerators.

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?

Everyone talks about the weather, but no one does anything about it. It is tme. People usually begin their talks with “Isn't it a nice day?” “Do you think it will rain?” “What a fine day!”
Many people think they can tell what the weather is going to be like. But they hardly agree with each other. One man may say, “Do you see how cloudy it is in the east? It's going to rain tomorrow.” Another man will say, “No, it's going to be fine tomorrow.”
People often look for the weather they want. When a farmer needs water, he looks for something to tell him it's going to rain, he want believe anything else. When friends have a travel, they are sure the weather is going to clear up very quickly.
