    题目列表(包括答案和解析)

    　　In these years, northern China is often hit by sandstorms. One of the reasons is that people are still cutting down more and more trees. As a result, a lot of good land has gone with them, leaving only sand.

    　　People suffered（遭受）a lot from sandstorms. When they came, car and bus drivers had to drive slowly：they could hardly see the road in front of them even during the day-time. In the year 2000, a very strong sandstorm happened in a certain city. It was one of the worst sandstorms that lasted nearly 2 hours. People couldn't see their hands before them. The streets were almost empty. The smell from the sandstorm was very bad. Some people disappeared in the sandstorm.

    　　Luckily, people in China begin to understand the terrible result. The Chinese government and people are trying their best to fight against sandstorms. They not only stop the people from cutting down trees, but plant more and more trees everywhere.

    　　Now, China has built the Great Wall across the northern part of the country. It will stop the wind from blowing the earth away. It will stop the sand form moving towards the rich farmland in the south. It has already saved a lot of land. But more “Great Green Walls” are still needed. They hope in a few years' time the whole country will be covered by forests.

    (1) In 2000, there was a strong sandstorm in a town.

    (　　)

    (2) People can't do anything to do with the sandstorm.

    (　　)

    (3) In ten years' time, China will may be covered by forests.

    (　　)

    (5) Chinese build the Great Wall across the western part.

         All our food comes from the soil (土壤). Some of us eat meat, but animals live on plants. If there are no
    plants, we will have no animals and meat. So the soil is necessary for us to live. 　　
         The top of ground is usually covered with grass or other plants. Plants grow in soil, which has a dark
    color. This dark soil is humus. Dead leaves, dead plants and animals' waste make it, but this takes a long time.
    When the humus has been made, plants can grow well in it.
         All soil needs food. If we don't give it any, the plants will be weak. Animals' waste is the best food for the
    soil, but chemical fertilizers (化肥) are also very useful. The same crop (庄稼) should not be grown in the
    same place every year. It is better to have a different crop. A change of crop and the use of a good fertilizer
    will keep the land in good condition (条件). 　　
         When the soil is dry, the wind blows it away. Sometimes heavy rain carries the humus down to a river.
    People should grow more and more trees and grass to stop wind from carrying the humus away. It takes
    hundreds of years to make humus, and so we must save every bit of it. Without soil, where can we grow
    food?

    A big, mighty(高大的) tree stood in a forest. Its branches(树枝) spread out and its roots (根) went deep in the earth. A lot of people came here to have a rest under it. And a lot of birds stood on its branches to sing and dance. The big tree was very proud all the time.
    At the foot of the tree, there was a little plant. The plant was thin, and seemed to be blown down by any of a little wind.
    One day, the two neighbors were having a little chat.
    “Well, little one,” said the tree to the plant, “why not put your feet deeply in the earth, and raise your head high in the air as I do?”
    “I see there is no need to do so,” said the plant with a smile. “In fact, I think I may be safer in this way.”
    “Safer?” said the tree. “Are you safer than I am? Do you know how deep my roots are in the earth and how strong my branches are? Who can possibly pull me out by the roots or bow my head to the ground?” And the tree didn’t want to say anything to the weak plant.
    But the tree was to regret its words very soon. One evening, a great hurricane(飓风) came. It blew the trees off their roots and almost destroyed the forest completely. It uprooted（将……连根拔起）the mighty tree and blew it away with great force.
    When the storm had gone, the villagers living nearby came to check the damage. The mighty tree lay on the ground, but the little plant still stood there.
    【小题1】Who was the big tree’s neighbor?

    A．People.B．Birds.C．A little plant.D．Branches.

    B．Because it was tall and thick.
    C．Because a lot of birds stood on its branches to sing and dance.
    D．All of the above.
    【小题3】Why didn’t the big tree want to say anything to the little plant?
    A．Because the big tree was tired.
    B．Because the little plant knew less than the big tree.
    C．Because the strong wind came.
    D．Because the big tree looked down upon(看不起)the little plant.

    B．They saw the big tree lying on the ground.
