    After that, we went on down the river. It was very dark that night and it wasn't easy to see where we were going. Suddenly, a big steamboat came at us very fast, and the next minute it was right over us. Jim and I jumped off the raft (木筏) into the water. The boat hit the raft and went on up the river.

    When I came up out of the water, I couldn't see Jim anywhere. I called out his name again and again, but there was no answer. “He's dead!” I thought. Slowly, I swam to the side of the river and got out. I saw that I was near a big old wooden house. Suddenly a lot of very angry dogs jumped out at me. They made a terrible noise and someone called from the house, “Who's there?”

“George Jackson,” I answered quickly. “I've fallen off a river boat.”

    Well, the people who lived in that house were very kind, and they took me in and gave me some new clothes and a good meal. I told them that my family were all dead, so they said I could stay with them as long as I wanted. It was a beautiful house and the food was good there, so I stayed.

    A few days later one of the slaves in the house came to me and said, “Come with me!” Together, we went down to some trees by the river. “In there!” he said and went away.

    On the ground, I found a man, asleep. It was Jim! I was really pleased to see him. When the steamboat hit the raft, Jim told me, the raft didn't break up. Jim swam after it and caught it. Then he began to look for me.

We decided to leave at once. It's all right living in a house for a little while, but you feel more free and easy and comfortable on a raft.

    Canadian Geese are large blue and white birds. When autumn comes, they have to fly south where the weather is warmer. The winters are so cold in Canada that the birds will die if they stay there.

    Last spring, Bill Lishman found sixteen young Canadian Geese on his farm. They had lost their parents. Bill thought, "These young birds won't know what to do in the autumn." He had a small plane and he decided to teach the birds to follow him. All through the summer, he went on short trips in his plane and the young geese flew after him.

    When the cold weather arrived in the autumn, Bill flew to Virginia in the United States, 600 miles south of his home in Canada. The geese followed him all the way. Bill left the geese in Virginia and he returned home.

    This spring, Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia to get them. He looked for them for two weeks, but he couldn't find them. When he arrived back home, he found the geese waiting for him. They had found their way home without him!

    Hi! I'm Maria. I have two boys. Tom is three years old and Tim is one year old. My family moved into an apartment a few months ago. Our house is on the second floor. But our neighbour downstairs complains at least once a day and we have got her note, saying "Please stop running and jumping on the floor."

    Since then, I have to do everything to keep the boys busy or out of the apartment during the day, but this can't stop my kids from making noise. They are just children under the age of four. Now the lady downstairs often bangs the walls when my boys run and jump in the rooms.

    However, she often plays movies loudly late at night. The noise wakes up my children at night and makes them cry.

    At the same time, we have another problem. The person on the third floor often walks too hard and wakes up my boys at 5:30 a.m. , but I think we have to face it.

    Usually my boys are sleeping from about 8:30 p.m. to 6:00 a.m. the next day. At least they don't annoy the neighbour downstairs during the hours.

    In about 1503, during Christopher Columbus's fourth and final trip to America, his ship was seriously damaged in a storm. Columbus and his men had to live on a small island for several months while they tried to repair their ship and return to Spain.

    At first, the local people on the island were very kind to the European visitors, giving them all the food and clothes they needed to survive. However, as the months passed, the local people became more and more unhappy with their guests, who were tricking and stealing from them. Finally the locals decided to stop helping. Without food or any way to leave the island, Columbus's group was soon in serious trouble.

    Luckily for Columbus, he had a book about the stars and planets on his ship. It described the movements of all the objects in the night sky. The book, written by a well-known German scientist, said there would be a total lunar eclipse(月食)and how long it would last.

    Columbus worked out the difference in time between Germany and North America. He then had a meeting with the local leaders just before the eclipse would take place. In this meeting, Columbus told them his god was angry because the local people were no longer giving food. So his god would take away the Moon to punish them. At the moment Columbus finished talking, just as he had planned, the Moon began disappearing.

    The local leaders grew frightened and quickly agreed to provide Columbus with food and anything else he wanted. But first, Columbus's god had to return the Moon. Columbus told them he would have to discuss the idea with his god on his ship. Knowing the Moon would stay completely hidden for about 48 minutes, Columbus returned just before the Moon began to reappear. From that day on, until they finally left, Columbus and his men no longer had any trouble getting the food they needed.
