We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

It began with a red paper clip and ended with a house. Kyle MacDonald, a 26-year-old Canadian, got a three-bedroom house through 14 trades (交换) that started with a single red paper clip.[来源:学。科。网Z。X。X。K]

Encouraged by Kyle’s successful experience, now more and more young people around the world are starting their own trading activities. They set up websites where people can trade things they don’t usually use with other people. A website called Peerflix allows people to trade their used DVDs. These traders usually prefer face-to-face trading, which means 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 more than 10,000 yuan. But she may still have a long way to go.

You may be puzzled about why people are doing this. In fact, everyone in the trade activities gets things that are useful to them. Just as Kyle said, “What’s more important to a man dying of thirst in the desert — one million dollars or a glass of water?” Kyle’s words probably show why these trades are poplar among young people.

A. Because they can make a lot of money by trading with other people.
