Nowadays, it is common that more and more high school students open their own micro blogs on the Internet. For one thing, it can provide a colorful platform to show their talent. For{#blank#}1{#/blank#},it is a useful way to release their{#blank#}2{#/blank#}(press). And all these make it more and more popular with high school students.{#blank#}3{#/blank#}many parents and teachers hold a different view. They think that managing one's micro blog will take a lot of time and energy，{#blank#}4{#/blank#}should be used to study.

    In my view, I am greatly in favor{#blank#}5{#/blank#}this activity. Today the Internet is playing{#blank#}6{#/blank#}important and essential role in our life .Therefore, as high school students of the Information Age, we need to learn to make use of this{#blank#}7{#/blank#}(mean) tool to communicate and display ourselves. What's more, opening and organizing micro blogs need various abilities such as writing, designing, being skillful at computer and so on. Only if we master those abilities can we make a successful micro blog. As a result, we improve ourselves while{#blank#}8{#/blank#}(organize) our micro blogs .

    In fact, micro blog{#blank#}9{#/blank#}(oneself) is of little harm. It is your attitude towards it{#blank#}10{#/blank#}matters. We should take the advantages and avoid some bad effects.

    When Joe was about to start school, all signs pointed to success. Yet things turned out  {#blank#}1{#/blank#}(be) quite disappointing. The fourth grade even found him at the bottom of the class. Joe struggled day and night, but  {#blank#}2{#/blank#}made him upset was that it did not work—until one stormy afternoon.

    On that afternoon, the math teacher was introducing difficult concepts  {#blank#}3{#/blank#}dark clouds covered the sky, and the storm set in. Although she tried to make the kids concentrate, the thunder won the battle for their attention. No one grasped the concepts. Except for Joe. He understood{#blank#}4{#/blank#} and answered all the questions correctly. The teacher patted him on the back and told him to go around to the others and explain how he had managed it. {#blank#}5{#/blank#}(encourage) by his newfound success, Joe moved quickly throughout the room. Soon math time  {#blank#}6{#/blank#}(follow) by the time for art. All children  {#blank#}7{#/blank#}(natural) drew dark pictures on such a day. Except for Joe.

    Since then, Joe started to work even  {#blank#}8{#/blank#}(hard) than before. His math teacher was always curious about the  {#blank#}9{#/blank#}(amaze) change: Why had that stormy day changed Joe?

    At the graduation ceremony, Joe presented the teacher with his most familiar  {#blank#}10{#/blank#}(possess) — the picture of bright yellow sun. On the picture Joe had written: This is the day I woke up to my brightness.

    Martin Strel swims with a knife {#blank#}1{#/blank#} (fasten) to his right leg—in case he meets sharks and other {#blank#}2{#/blank#}  (dead) sea life in the world's wildest waters. {#blank#}3{#/blank#} 61-year-old marathon swimmer has announced the {#blank#}4{#/blank#} (tough) challenge of his life: a 10,000-mile-around-the-world journey on water {#blank#}5{#/blank#} (draw) public attention to the increasing water {#blank#}6{#/blank#} (pollute). He aims to circle the globe in about 450 days, passing through oceans, rivers,{#blank#}7{#/blank#} (canal) and other bodies of water in more than 100 countries. He will swim about 5 to 12 hours each day, depending on the weather. A boat will go {#blank#}8{#/blank#} him and offer emergency support and space for small breaks.

    Since 2000, Strel {#blank#}9{#/blank#} (swim) the entire length of five rivers in China, America, etc. Strel will not be alone in the water. He says he welcomes {#blank#}10{#/blank#} is interested in joining him for parts of the route.

    Experts have started working on {#blank#}1{#/blank#} unbelievable project to make a robot made by NASA act like a human.

    {#blank#}2{#/blank#}(name) Valkyrie, the robot looks like a woman and may be used to explorer Mars one day. It {#blank#}3{#/blank#} (invent) by NASA scientists to compete in the DARPA Robotics Challenges(DRC). It is 1.9 meters tall and {#blank#}4{#/blank#} (weight) 125 kilograms. It comes with a series {#blank#}5{#/blank#} cameras, sonar, and other sensors spread across its body to help it move around.

    Valkyrie is powered by a battery on its back, which can keep it {#blank#}6{#/blank#} (operate) for an hour. It can walk on {#blank#}7{#/blank#} (it) own, pick up objects and control many objects and tools, {#blank#}8{#/blank#}is part of the requirements for the DARPA challenge.

    The machine can walk on two legs and perform basic{#blank#}9{#/blank#} (move) at present. However, the team from Scotland's Edinburgh University wants to give it {#blank#}10{#/blank#} (many) skills. It is hoped that the new and improved robot will work along with astronauts in space.

    I was traveling in a small place in New York. That place had no taxi for a short {#blank#}1{#/blank#} (distant). One had to take a rickshaw(人力车).

    I called out for an old man in the waiting line. Before I got on the rickshaw, I {#blank#}2{#/blank#} (automatic) asked how much he would charge to take me across to the Mall. I {#blank#}3{#/blank#} (tell) “10 dollars”. Then I started bargaining. He just gave a hard smile and said, “Whatever you feel like, please give me. It is not necessary{#blank#}4{#/blank#}(bargain) on this small amount.”

    I was a bit ashamed at myself and kept quiet while he continued, “{#blank#}5{#/blank#}(like) those taxis, my vehicle does not run on petrol or diesel(柴油) or even gas;{#blank#}6{#/blank#} runs on my sweat. So please give it to me {#blank#}7{#/blank#} a smile, for the money has to feed so many {#blank#}8{#/blank#}(hunger) mouths at home.”

    When we reached the Mall, I gave him the money and the smile{#blank#}9{#/blank#} requested and added a gentle pat on his back. He smiled back as if to give me a receipt and I would preserve his smile for {#blank#}10{#/blank#} long time.
