    In nature，you may see many insects and animals of different colors．Have you ever wondered why?

Locusts(蝗虫)are super delicious food for birds，but it is not always an easy job for birds to catch them．It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies．The reason is that the colors of locusts change with the colors of crops(农作物)．When crops are young，locusts look green．But when autumn comes，locusts change to the yellow and brown color as crops do．

    Brown bears，tigers and other animals move quietly through forests．They can't be seen easily by their enemies．This is because they have colors similar to the trees．For the same reason．polar bears that live on a land of snow and ice are white．Butterflies and bees living among the flowers are colorful like flowers．Soil insects are mostly dark—colored and they live under the soil in a dark and wet environment．However，insects with colors different from plants can easily be found and eaten by others．So in order to survive ， they have to hide themselves in the daytime and appear only at night．

    Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger．As the ink spreads over．its enemies will not find themselves suddenly in a dark world．At the same time the ink fish immediately swims away．That is how it keeps itself save though it is not strong at all．

    There are some easy things you can do to protect the environment and the earth. Choose ideas from the list or come up with a few of your own.

    ·Plant flowers, grass or trees.

    ·Whenever you visit a park or beach, take away what you bring there-keep rubbish in a bag until you can put it in a dustbin.

    ·Turn off the lights, TV sets when you leave the room. This saves a lot of electricity.

    ·Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

    ·Keep the doors and windows closed in winter to keep cold air in.

    ·Give your old books and magazines to a library instead of throwing them away.

    ·Give your old clothes to poor children you know instead of throwing them away.

    ·Use both sides of paper.

    ·Stop pouring dirty water into the rivers or lakes nearby.

    ·Encourage all your friends to do the same things you do to help protect the earth.

    You don't have to wait until Earth Day to do these things. Make every day Earth Day.

    If everyone makes a contribution to protecting the environment, the world will become much more beautiful.

    Humans can go to the hospital when they're ill. But as for animals, what should they do？To stay healthy, animals have their own ways to heal(治愈)themselves. Now let's get to know their special skills.

    Skill One

    Have you ever seen your dog or cat lick(舔)its wounds？Why do they do it？It probably feels good, but it's good medicine. Licking cleans a wound, and saliva(唾液)has chemicals that kill germs(细菌).

    Skill Two

    To avoid diseases, many animals have good living habits. They hate to be dirty. Most animals separate their pooping(排便)areas from their eating areas. Horses poop far away from the grass they eat. Rabbits put their poop in special pooping areas.

    Skill Three

    Have you ever heard of the expression "starve a fever(发烧时宜饿)"？Many animals stop eating when they're ill. When a sick animal stops eating, it can stop germs from getting necessary things.

    Skill Four

    Another way that animals heal themselves is to raise their body temperature. High temperature can kill germs. Warm—blooded animals(like us)get fevers to fight with germs.

    Cold—blooded animals(like snakes)look for pieces of wood or rocks heated by the sun.

    Fish move to warmer waters.

  Why are so many people so afraid to fail ? Quite simply because no one tells us how to face the failure (失败）. In fact, failure can become experience that means growth. We forget that failure is part of the human condition and that every person has the right to fail.

Most parents work hard to prevent failure or protect their children. One way is to lower (降低)standards. Nearly 60% of the parents choose this way. When a child finishes making a table, the mother describes it as "perfect" even though it doesn't stand still. The other way is to blame (责怪）others. If John fails in science, his teacher is unfair or stupid.

There's a problem with the two days. It makes a child unprepared for the real life if they don't meet enough failure. The young need to learn that no one can be the best at everything, no one can win all the time. The young should be allowed to experience failure. 

Failure never gives people pleasure. It hurts both grown—ups and children. But it can be really good to your life when you learn to use it. 

 If you think of after-school activities as a waste of time, you are wrong ! After-school activities help us grow up in many ways. Above all, they offer us chances to practice what we learn in class. Through various activities, {#blank#}1{#/blank#} and a lot of new things that we can't learn from our books. What's more, they help to develop our abilities that we need both for our studies now and for our work and life in the future.

{#blank#}2{#/blank#} , so after school we all need to relax ourselves. After-school activities just make it possible for us to breathe fresh air outside and remove our tiredness. {#blank#}3{#/blank#} .

 Some after-school activities will make us useful and helpful to others. Some can keep us strong and healthy: {#blank#}4{#/blank#} . So, all the students: get out and take an active part in various after-school activities!
