What makes 15,000 men and women run for hours, and what makes them run through the streets on a cold day without coats? I was one of those runners.  The race is called marathon (马拉松).

I had never run more than eight miles before, and here I was training.  Since the race is in April, I had to run throughout the winter, and in Boston, winters are cold. For most people, just putting on their shirts, sweaters, jackets, and hats is exercise enough. I found myself out on the dark streets, running along ice sidewalks (人行道). Even in gloves, my fingers got so cold that they looked like red carrots. My nose didn't get warm until lunchtime !

Finally, the big day arrived. The weather was cold, with ice and rain. Bang! The gun sounded, and we started. I didn't go anywhere at first because I was standing behind so many people. I had to wait for them to move.

At first, the running was easy.  The other runners just seemed to pull me along. Somewhere around the 20-mile mark I even said to myself, "This is nothing, why did I train so hard?"

Then I hit "the wall". "The wall" is what marathon runners call the special point. I knew my body reached the point and I thought I couldn't go any more. I was out of breath and my legs turned into pieces of wood.  I was almost falling down.  I can't remember anything about the last five miles of the race.

I kept running though. At last, I heard a voice at the finishing line.

"You look good," my friend Ted said. "How did it feel?"

"Wonderful !" I replied.

For everything, if you devote yourself into it, there will be a way. I finished the race, at least, in my heart, I was the winner.

1.Which one best describes the weather on the race day?

The first chocolate was eaten by people in South America hundreds of years ago. In those days, the people did not really eat chocolate. They used the cocoa bean（可可豆）to make a chocolate drink and they enjoyed it very much. Many years later, the cocoa bean was brought to other countries and people came to love the taste of chocolate.

    In 1824, John Cadbury opened a small shop in Britain. One of the things he sold was chocolate drink. In 1831, he opened a factory to make chocolate drink. He wanted to encourage people to drink chocolate instead of other drinks. A few years later, a man called Joseph Fry found a way to make chocolate instead of only drinking it. But at that time chocolate was very expensive and only the rich people could buy it. Later, more and more chocolate bars were produced and sold, it became cheaper.

    However, at first only plain chocolate （a kind of chocolate without milk and with very little sugar）was produced. Milk chocolate came later and this was made by adding milk to the chocolate. The first milk chocolate bar was made in Cadbury’s factory in 1897. Their most famous chocolate, Cadbury’s Milk Bar, was made in 1905. It has been the most popular chocolate in Britain and around the world for over 100 years. The Cadbury factory is still in Britain and the chocolate produced there is eaten all over the world. Every year, thousands of visitors visit the factory in order to see how chocolate is made.
