Man began to make use of fire long long ago. Fire is useful in many ways, but sometimes it is dangerous. If you are not (1)        with it, it can burn things or (2)       hurt you. A big fire can (3)        forests and tall buildings. Sometimes a piece of (4)        paper can cause a big fire. So please remember (5) ______      in the dry places like woods and forests (6)        throw a cigarette end on the grass and it’s also important for you to put the candles in the 7)       place. When you use candles at home ,you should (8)        your long hair away from the fire.
But if there is a (9)        in our building, what should we do with it? Pour some water (10)       your clothes.

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.
