    　　It's important to learn about protecting our environment. Here is a 5R rule for us:

    　　1. Reduce

    　　If you want to reduce waste, you should use things wisely（胆智地）. A large number of trees are being cut down to make paper. If everyone uses a little paper carelessly and throws it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste.

    　　2. Reuse

    　　You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters.

    　　3. Recycle

    　　Bottles, cans（罐子）and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted（熔化）and the metal things are made for new coke cans.

    　　4. Recover

    　　When you buy a box of apples, there may be a few rotten（腐烂的）apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.

    　　5. Repair

    　　If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing something. It is true that North America is a “throw-away” society, but the time has come to change our way of life so hat we can protect our environment. Every one of us should try our best.

    (1)The “Reduce” rule mainly requires（要求）us ________.

    [　　]

    A．to use things wisely

    B．to cut down many trees

    D．to throw away your old clothes

    (2)What's the right order（顺序）of recycling coke cans?

    a. collect the used cans

    b. melt them

    c. smash them flat

    d. send them to a factory

    [　　]

    A．a,b,c,d

    B．a,d,c,b

    C．d,b,c,a

    D．c,a,b,d

    (3) The “Recover”rule mainly requires us ________.

    [　　]

    A．to throw waste things away

    B．to cover waste things with earth

    C．to get back the useful parts

    D．to throw the whole things away

    (4) Which is the best way to do with your broken tables?

         1970 was World Conservation (保护) Year. The United Nations wanted everyone to know that the world
    was in danger. They hoped something could be done.
         Here is one example of the problem. At one time there were 1300 plants and flowers in Holland, but now

    young people have known this. Many of them are helping to save our world. For example, they plant trees. In
    a small town in the USA a large group of girls cleaned the banks of 11 kilometres of their river. Young people
