"Listen carefully to what I say,"  the time traveler said, "I shall tell you something that you will not agree."

    "Why will we not agree?" I asked.

    "Because the science and mathematics you know are not correct," he said. "You believe there are only three dimensions(三维空间)-length, breadth(宽) and thickness."

    "There is nothing to argue with that, "  the youngest member of our little group said.

    "Exactly!"  the time traveler answered, "But there is also a fourth dimension - time."

    "We all know about time, " another member of the group said. "Time passed."

    "I do not agree,"  the time traveler said, "Length, breadth and thickness do not pass. They stay in the same place in space.  We move about them. I can prove that time is the same. It does not pass. We move in time the same way that we move in breadth, length and thickness."

    None of us believed the time traveler, and we argued with him for many hours.

    "If we could travel back in time,"  the scientist said, "We could do things to change the future."

    "If we could travel forward in time," the doctor(博士) said, "we could do things that change our present."

    The time traveler smiled, "It is clear," he said, "that there is only one way I can show you that I am right. We must do an experiment. Please wait here."

    He left the room and soon returned, carrying what looked like a clock.

    "This is a model of a time machine. It took me two years to make it," the time traveler said. "I want all of you to understand that when I start the machine, it will immediately travel in time and disappear from the present."

    He turned to the youngest of all. "Give me your hand," he said.

    The young man put out his hand. The time traveler took it and placed it on the machine. Immediately, there was a sudden wind, and the little machine disappeared.

    I was certain this was not a trick, but the doctor was not so sure.

    "Are you asking us to believe," he said, "that the machine is now in a different time?"

    "Certainly! In my laboratory, a full-size machine is almost complete. As soon as it is complete, I shall send myself on a journey through time. Would you like to see my machine?"

    "Are you serious about this?" the doctor asked.

    "I have never been more serious about anything," the time traveler said, "Come."

    We followed him to his laboratory. There, we saw the actual machine, not quite complete, but large enough for a man to sit in.

    Once there was an apple tree which a little boy always played around. When the little boy grew up, he no longer played around the tree.

    One day the tree said, “Come and play with me.” The boy answered, “I need money.” “Sorry, you can sell the apples for some money.” The boy did that and left happily.

    After a few years, the boy came back. The tree said, “Come and play with me.” The boy said, “I don't have time. I need a house.” “You can cut off my branches (树枝) and trunk (树干) for a house,” answered the tree. The boy did so.

    Twenty years later, the boy came back again. “My boy, the only thing left is my dying roots (根),” said the tree. “I don't need much now, just a place to rest. I am too tired,” answered the boy. The tree then smiled with tears.

    This is a story of everyone. The tree is our parent. No matter what we need, parents will always be there and give everything they have to make us happy.

    Shu-How Lin was born on August 23,1988 in California in the USA．He's the newest well-known NBA professional basketball player. His ancestors lived in Fujian Province in China．In 1977,his parents moved to America．Although they live in the USA, they know they are Chinese. And they love their motherland. They try their best to earn more honor（争光）for China.

    When Shu-How was at high school, he showed a great interest in playing basketball. He practiced basketball much harder than any other student in his school. Because of him, the school team became the champion of all the high schools in America, which had never got a champion before. Meanwhile（同时）,he studied particularly hard during high school. He always got "A" in most of his subjects.

    After high school, his dream was to join a university, which was famous for basketball, to major in basketball. But none of these universities in America accepted him. They thought that he was just a Chinese and a Chinese could hardly become an excellent professional basketball player. He felt so sad and he had to attend Harvard University by his good grades, where professional basketball players are not wanted. But before long, he became the first man in Harvard who entered NBA after 1954.

    Shu-How never gave up his basketball dream. He joined several NBA teams, but he was never given a chance to show himself in each game. One day, two players of his team were badly hurt. There were no more players who could play the game. The coach had to let Shu-How go for it. This was a great chance for him. He showed his talent in this game. He got 25 scores!

    After that, Shu-How became one of the most outstanding basketball players around the world. He set a great example to all of us. According to him, we know nothing is impossible if we try our best.

I was living in a house with a long history in Halifax, Nova Scotia five years ago. One day, one of my friends from the West Coast came to visit me. He was 1 for three weeks so he brought a lot of bags and suitcases, and other things like a 2  . I told him that he could sleep on the bed in the front living room.

One morning after a late night of drinking, my friend ran into my room, shouting, "FIRE! FIRE!"Without 3  , I jumped out of bed. The floor was 4  against my feet as I ran out into the hallway, right behind my friend. I couldn't see the fire anywhere, 5  as we ran towards the front door, I could hear the 6  making a loud noise all around me. It was inside the 7  . We ran out into the front yard and 8  at the house, seeing black smoke coming out of the 9  house.

We were standing there watching the house when I looked down and 10  all of my friend's bags and suitcases 11  lined up on the front grassland, including his basketball. When he noticed the house was on fire, he took 12  out to the grassland first. And then he came back to 13  me about it. That fire had started in the basement(地下室), and it spread up into the walls and was burning the 14  we were standing on. The floor and much of the house fell down not long after we came out. The firemen said we were very 15  .

Of course, we are not friends any more.

Everyone wants to live longer, so to keep healthy is very important. I have a neighbor. She is {#blank#}1{#/blank#} old lady. She can read newspapers, watch TV and search on the Internet to learn {#blank#}2{#/blank#}( anything) new. She often does Tai Chi in the morning and dances in the evening. {#blank#}3{#/blank#} she is over 70, she looks young and beautiful . Last week a reporter from a magazine interviewed(采访) her and asked her {#blank#}4{#/blank#}( tell) the reason why she kept so young and healthy. She answered with a smile.

"I have a secret of {#blank#}5{#/blank#}( stay) young and healthy. It is easy. Keep your mind active, be {#blank#}6{#/blank#}( interest) in the world around you, and learn at {#blank#}7{#/blank#}( little) one new thing every day. Don't think you are too old to go back to school. I know two men entered a college of arts when they were 70 years old. They {#blank#}8{#/blank#}( study) there for 6 years and now they are{#blank#}9{#/blank#}( write). Another man went to a tennis school at the age of 71 and now he is good at playing tennis. He said it's good {#blank#}10{#/blank#} his health. Some people may say staying young is easy only for those who live in the future. In fact, no matter how old you are, you can make it."
