Many people believe that, by the year 2100, we will live on the planet Mars(火星). Here is what life could be like.
    First of all, transport should be much better. By 2100, spaceship can travel at half the speed of light. {#blank#}1{#/blank#}
    Secondly, humans need food, water and air to live. Scientists should be able to find plants that can grow on Mars. These plants will provide us with food and air.
{#blank#}2{#/blank#} We could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
    Life on Mars will be better in many ways. {#blank#}3{#/blank#} It is possible to live in a large building with many bedrooms. Then, robot will do most of the work, so we have more time for hobbies.
{#blank#}4{#/blank#} Every student can study, do their homework on the computer and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
    However, in some ways, life on Mars may not be better than that on the earth today.  {#blank#}5{#/blank#} Meals will probably be in the shape of pills(药片) and will not be as delicious as they are today. Also, space travel will make many people feel ill.

One day, Mr. White told the class to get ready for a hobby show. The students {#blank#}1{#/blank#} the whole morning getting what they were going to show.
All the students came back on time but Bob, the laziest {#blank#}2{#/blank#} in his classmates' eyes. It seemed that it was very {#blank#}3{#/blank#} for Bob to have a hobby. But to their surprise, Bob came back with many {#blank#}4{#/blank#} stamps in his hand. Mr. White was very happy after watching them. However, Bob was going to {#blank#}5{#/blank#} them back.
“Bob, you can't take them back until the others watch them this afternoon,” said Mr. White.
“But I am sorry they are my brother''s,” he answered. “He doesn't want them to be out of our home for long. He's afraid that they will be {#blank#}6{#/blank#} .”
“Bob, you should show some of your own {#blank#}7{#/blank#} here, not someone else's. Mr. White became kind of angry.
But Bob's words made him even {#blank#}8{#/blank#} . “Mr. White, it's true that I have a hobby. My hobby is watching my brother collecting stamps.”

    There are four seasons in the year. Then I will i{#blank#}1{#/blank#} the four seasons of the year.

    In the year, the f{#blank#}2{#/blank#} season is spring. Spring is a beautiful season.

    Summer comes a{#blank#}3{#/blank#} spring. It's the h{#blank#}4{#/blank#}in a year. In summer there are some persons at home and t{#blank#}5{#/blank#} on the air-conditioner(空调). Summer is hot and sunny. But I like summer very much. Because I can eat some ice-creams and go s{#blank#}6{#/blank#}.

    I think autumn is better than summer. Autumn is a wonderful season and a h{#blank#}7{#/blank#} season. In autumn I can eat so many fruit and food. And the trees are golden.

    Winter is the l{#blank#}8{#/blank#} season of the year. In winter I can play s{#blank#}9{#/blank#} with my friends.

    In my city, every season has three m{#blank#}10{#/blank#}. The weather of the season is different from that of any other.

    It was very cold. It was snowing fast and almost dark; the evening—the last evening of the old year was drawing in. In the cold and darkness there went along the street a poor little girl, w{#blank#}1{#/blank#}a cap and shoes. When she l{#blank#}2{#/blank#}her home she had shoes on . H{#blank#}3{#/blank#}, they were much too large for her f{#blank#}4{#/blank#} —shoes that her mother had used till then and the poor little girl l{#blank#}5{#/blank#}them when she was running across the street when two carriages(四轮马车) were p{#blank#}6{#/blank#}by terribly fast. When she looked for them one was not to be found, and a boy hid the o{#blank#}7{#/blank#}and ran away with it, saying he would use it as a house for his mouse.

    In the old c{#blank#}8{#/blank#}that she wore were boxes of matches, and she carried a box also in her hand. No one had brought so much as a box all the long day, and no one had g{#blank#}9{#/blank#}her even a penny.

    Poor little girl shaking with cold and hunger, she walked slowly, q{#blank#}10{#/blank#} and carefully along , a perfect picture of great unhappiness.

    The {#blank#}1{#/blank#} saw a most wonderful sight. Birds were flying about and singing, and flowers were {#blank#}2{#/blank#} through the green grass. The trees were waving their arms {#blank#}3{#/blank#} in the warm wind. Children were running about and sitting in the {#blank#}4{#/blank#} of the trees. It was a {#blank#}5{#/blank#} scene.
