The giant panda is one of the most popular animals in the world. A giant panda can grow up to 1.5 meters long and weigh up to 160kg. People think the giant panda is very lovely. ①So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that they are in danger and raises money to save them.[来源:Zxxk.Com]

The giant panda only lives in the wild in China. In the early 1980s, were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where pandas can live has become smaller.

The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to increase the size of panda reserves(自然保护区). Some reserves need to be joined together by planting bamboo between them to make “corridors”. These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look for food. ②People are working very hard to make sure the giant panda does not die out.

It began with one red paper clip(回形针)and ended with a house. Kyle MacDonald, a 26-year-old Canadian got a house with three bedrooms through 14 trades(交易)that started with a single red paper clip.

Now more and more young people around the world like this kind of trading activities. They set up websites and trade on the Internet. People trade things they do not usually use with other people. A website called Peerflix allows people to trade their old possessions. These traders usually prefer face-to-face trading, in this way they don’t have to worry about who is going to pay for the delivery(递送).

Last year, a young girl in Beijing decided to follow the example of Kyle. She started with a paper clip and hoped to get a house in the end．After several trades she now has a piano which is worth more than 10, 000 yuan. But she may still have a long way to go.

Maybe you can’t understand why people are doing this. As Kyle said, “What’s more important to a man in the desert—one million dollars or a glass of water?” Kyle’s words probably show why these trades are popular among young people.
