根据短文内容，判断下列句子的正误，正确的用“T”，错误的用“F”。（每小题1分，共5分）

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.
