Hello, everyone! My name is Jenny Green. My first name is Jenny and my last name is Green. I am {#blank#}1{#/blank#}（十）years old. I like {#blank#}2{#/blank#}(夏天) and I can swim. I often go swimming on{#blank#}3{#/blank#}（星期天）. There is a swimming pool (游泳池) behind my home. It is{#blank#}4{#/blank#}（小的）. but I like it. Look at the{#blank#}5{#/blank#}( 照片) in my hand. This is my father. He is a{#blank#}6{#/blank#}(医生), he works in a{#blank#}7{#/blank#}(医院). It is{#blank#}8{#/blank#}( 在….附近) my home. He is{#blank#}9{#/blank#}( 四十) years old. My father and I are going to see my{#blank#}10{#/blank#}叔叔) tomorrow. He is a good policeman.

    Trees are useful to man in three very important ways. They provide him with wood and other products, they give him shade, and they help him prevent droughts {#blank#}1{#/blank#} floods.

    Unluckily, in many parts of the world, man has not realized that the {#blank#}2{#/blank#} (three) of these services is the most important. In order to make money {#blank#}3{#/blank#} (quick) from the trees, he has cut them down in large numbers. Two thousand years ago, a rich and powerful country cut down thousands of trees {#blank#}4{#/blank#} (build) warships. It built up a strong empire (帝国). But without the trees, {#blank#}5{#/blank#} (it) soil became poorer and poorer. When the empire fell to pieces, the country {#blank#}6{#/blank#} (find) itself facing with floods and hunger.

    Even though a government realizes the {#blank#}7{#/blank#} (important) of trees, it is difficult to make the people realize this. They cut down trees but are too lazy to plant and look after new trees. So, unless the government has {#blank#}8{#/blank#} good system of control, or the people are educated, the forests may slowly disappear.

    This does not only mean that there will be fewer trees. The results are even {#blank#}9{#/blank#} (serious). If there are tree roots which break the soil up and allow the rain to sink in, the soil can be bound (受约束的).

    This prevents the soil {#blank#}10{#/blank#} being washed away. But if there are no trees, the soil will become hard and poor. This causes floods. And the rain carries away the rich topsoil (表层土) in which crops grow. When all the topsoil is gone, nothing remains but useless sand.

    Have you ever been cycling(骑自行车运动)? This spring my elder brother and I {#blank#}1{#/blank#}(spend) a long weekend cycling in the countryside. We rode {#blank#}2{#/blank#} (slow) along because we hadn't come to break any speed records, or to do sports. We just wanted {#blank#}3{#/blank#}(get) some fresh air and a break from schoolwork. We really had a great time {#blank#}4{#/blank#}(ride) along country roads. And there was one of the best things about our trip that made us happy: every few {#blank#}5{#/blank#}(kilometer) there was a village where we could find everything we needed.

    All the local people were really friendly. However, on the {#blank#}6{#/blank#}(two) day, something happened. We were going down the hill when my brakes(剎车)started making a {#blank#}7{#/blank#} (noisy), but I didn't mind at all. At midnight we were woken by the noise in the hotel. We were tired when we set off the next morning, but soon felt {#blank#}8{#/blank#}(cheer) when the sun came out.

    What we enjoyed {#blank#}9{#/blank#} (our) most about cycling is—it's simple and fun. I think nothing is {#blank#}10{#/blank#} (good) than cycling if you're looking for a break that is active and cheap. Why not have a try?
