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.

 There are many wetlands (湿地) in China and some of them have become the world's important wetlands.

The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The world's largest Milu Deer Nature Reserve (自然保护区) is in them. More than 700 Milu deer live freely there. There are not many red-Crowned cranes in the world, but every winter you can see some in the red-Crowned Nature Reserve in the Yellow Sea Wetlands.

      The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife (野生动物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.

      Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands. 

1.The Chinese Yellow Sea Wetlands are in the west of China.

2.Usually the weather in the wetlands is pleasant.

3.February 2nd is the world's wetlands Day.

4.We must protect wetlands only because they can offer food to the animals and birds.

5.Wetlands are valuable resources of land on the earth.
