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.

We drink tea every day. But more than three hundred years ago most of the people in Europe (欧洲) did not know anything about tea. Some people heard about it, but very few of them know what to do with it.
　There is a story about an English sailor (水手) who went to countries in the east, the west and the south. He went to India and China. One day he came home and brought some tea as a present for his mother. She told her friends about the present and asked them to a "tea party". When her friends came to the "tea party", the old woman gave them brown tea-leaves. The old woman's friends began to eat them. Of course, nobody liked the tea-leaves.
　At that time the sailor came in. He looked at the table and said, "Mother，what did you do with the tea?"
　"I boiled it，as you said."
　"And what did you do with the water?"
　"I threw it away(扔掉)，of course." answered the old woman.
　"Now you may throw away the leaves，too，" said her son.

　　Expert(专家)say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger(手指)with his eyes still closed, begging(请求)for one more minute to sleep. Like thousands of students “early birds” in China, he has to get up before six every morning.
　　 A report shows that without a good night’s sleep, students seem to be weaker(虚弱)than they should be. Many students have fallen asleep(睡觉) during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.
　　 Experts have ever said that the students should develop good study habits. So some clever students never study late, they are able to work well in class.
【小题1】The 10-year-old boy begged for more minute to sleep because__________.
