    任务型阅读  阅读短文，按要求完成各题。

    At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars. Our own planet, Earth, is becoming more and more crowded and polluted. Luckily, we can start again and build a better world on Mars.

        First of all, transport should be much better. At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months. However, by 2100, spaceship can travel at half the speed of light. It might take us two or three days to get to Mars!

        Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can be grown on Mars. These plants will produce the food and air that we need. However, can these plants produce water for us? There is no answer now.

        There is a problem for us to live on Mars. Mars suck us much less than the Earth does. This will be dangerous because 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 than that on Earth in many ways. People will have more space. Living in a large building with only 10 bedrooms is highly possible. Many people believe that robots will do most of our work, so we have more time for our hobbies.

        There will probably be no school on Mars. Every student will have a computer at home which is connected to the internet. They can study, do their homework 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. Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today. Also, space travel will make many people feel ill. The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.

    阅读理解。
        Plants and animals, including humans, need food and water to live on. These are from the  natural
    resources(资源) on Earth. To protect these resources, we need to keep the air clean and the water
    drinkable. We need to keep the soil (土壤)healthy. How do we do that?
    Protect the land
        The soil that covers fields and farms provides much of the food we eat. Human activities  such  as
    plowing(耕) fields, mining(采矿), and building highways can destroy (破坏)the land. Erosion  happen
    when wind and water carry away the soil. Soil erosion can turn rich farmland into a desert  wasteland.
    So does this mean we shouldn't build a highway or plow a field? Of course not. But  it does mean  we
    might think about Earth-friendly ways of doing those things.
    Today farmers plow their fields in different ways to prevent erosion. They try to use less water for their
    crops. They keep animals from eating the growing grass in  just one  area. Farmers also plant  trees  to
    prevent erosion from happening.
    Save the Trees
        Another human activity that damages the land is deforestation(采伐森林). People take away a large
    number of trees from a forest. Millions of square kilometers of forest disappear each year. When  this
    happens, many plants and animals lose their  places to live. They may die  out, or  become  very  few.
    Scientists haven't even discovered all the living things in the forest. We may be losing some without even
    knowing they are there. Trees absorb (吸收)and use carbon dioxide (二氧化碳)when they make food.
    Environmentalists encourage careful management of the forests. They ask people to replant trees  after
    they cut down the forest.
    Recycle, Reuse, Reduce
        People throw a piece of paper into the wastebasket after using it. The paper becomes trash.  Where
    does the trash go next? Much of our trash ends up in landfills(垃圾填埋地). They take up valuable land
    and sometimes pollute the water, air, and land around them. More than a third of the  trash in  landfills  is
    paper. Recycling, reusing, and reducing what you throw away can cut down on the need for more landfills. In fact, we can recycle about eighty percent of household trash.
    1. What does the underlined word erosion mean?
    A. Plowing fields and mining
    B. Cutting down trees and farming.
    C. Wind and rain carrying away soil.
    D. Building highways on the farmland.
    2. Why do we need to save the trees?
    A. To discover more new trees every year.
    B. To encourage careful management of the forest.
    C. To take away a large number of trees from the forest.
    D. To keep good places for animals and plants to live in.
    3. How much of the trash can we recycle?
    A. All the trash.
    B. Very little.
    C. One third.
    D. Four fifths.
    4. What's the purpose of the author writing the passage?
    A. To ask people to look for places to plant trees.
    B. To tell people how to protect natural resources.
    C. To show how the lands are destroyed by people.
    D. To discuss ways of protecting animals and plants.
