Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father's wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.

    "Dad will be really mad if he finds out you've been playing with his new computer." Jason said. "He told us not to touch it."

    "He won't find out, "Mark said." I'll just have a quick look and shut it down."

    Mark had been scolded before for touching his father's equipment. But his curiosity was difficult to control and this new computer really puzzled him.

    It was a strange—looking machine--one his dad had brought home from the laboratory where he worked. "It's an experimental model, "his father had explained," so don't touch it under any circumstances." But his father's warning only made Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: "SPACE TRANSPORTER."

   "Yes!" Mark cried excitedly, "It's a computer game. I knew it! Dad's only been pretending to work. He's really been playing games instead. ''A new message appeared on the screen：

    "ENTER NAMES

    VOYAGER 1…

    VOYAGER 2… "

    Mark's fingers flew across the keyboard as he typed in both of their names.

    "INPUT ACCEPTED START TRANSPORT PROGRAM. AUTO RETRIEVE INITIATED(自动回收程序已启动). "

    The screen turned even brighter and a noise suddenly rose in volume.

    "I think we'd better shut it off, Mark, "Jason yelled, reaching for the power switch. He was really frightened.

    But his hand never reached the switch. A single bean, of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒), until the)themselves seemed to be glowing. Then it died down Just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.

    "TRANSPORT SUCCESSFUL. DESTINATION：MARS. RETRIEVE DATE：2025."

    On 26 February, I got an email from my friend David, asking me to go to Tanzania to train their software engineers. The company is located in Dares Salam, a beautiful coastal city to the west of the Indian Ocean. I stayed for about two weeks in that city last time I was there. During my stay there, David took me to the nearby beach and we had a wonderful walk along the coast which had left a deep impression on me. I was impressed by the ocean water and the deep blue sky.

    After more than 19 hours of air travel, I was finally here at Dares Salaam Airport. The temperature here was high as usual- over 30 degrees. I felt short of breath because of the unbearable heat in this tiny hall. When I finally got my turn, I handed my passport to the officer in front of me, He had a close look at my passport. Then he asked the purpose of my stay, I told him I just wanted to travel here.

    "Where do you want to visit?" he asked again.

    "Dares Salsam."

    "What's your job?" he asked.

    "I'm a software engineer.

I will never forget this experience that I had. I still love this country.

①My daughter's pet fish is dying. Recently I find myself spending minutes and even hours staring at the clear round bowl, hoping for another performance of its wonderful dance. To be honest, I am not a fish person. Compared with cats and dogs, fish can neither play nor walk with me. To me, they are just so boring.

②But every morning now, I tap on the bowl, shake out some fish food and carefully throw it into the bowl, hoping the fish can eat it with the least effort. I try to make the fish more comfortable. Yet there's so little that I can do. The fish just remains still (一动不动的) at the bottom of the bowl.

③"Come on! Eat something!" I say. And suddenly I realize that somebody said the exact same sentences to me before. Many times.

④I think of the banana pancakes that my mother would serve me every time I became sick and stayed in bed. They were my favorite treat and always made me feel much better. "Come on! Eat something! Your body needs to be strong!" My mom would always say. What made me even warmer was the idea that she would always, always be there when I needed her.

⑤Many years later, I tried to do the same when my mother became sick. She was only 61 but seemed to get weaker every day. "Would you like some green tea?" Again and again, I would ask, "What about some cake? Hot chocolate? Strawberries?" I gently encouraged her to eat because I didn't know what else to do. "Please, Mom! Eat something! Your body needs to be strong!" But she would not. There she was, lying still on the bed, with her eyes closed. That was the last time I saw her.

⑥The fish is still lying at the bottom of the bowl. I stare at it and suddenly a familiar (熟悉的) face comes into my mind. Then I say in a low voice, "Mom, ▲ ."

Welcome to my classroom! I'm Tom. This is my schoolbag. I always put it on the desk, but now it's under my chair. It's black and white. Black and white are my favorite colors. My pencil box and books are in it. What's in the pencil box? A ruler, two pencils, a pen and an eraser are in it. The ruler is white. It's new. It is my friend Lucy's ruler. She has two, and she lends(借) one to me. The pencils are nice. One is black, and the other is red. The red one isn't my pencil. It's Jim's. The black pen is mine. It writes very well. The eraser is white. I take these things to my school every day.
