The World’s Water Shortage(缺乏)

    The world is not only hungry，but it is also thirsty for water．This may seem strange to you，  since nearly 70 percent of the earth’s surface is covered with water．But about 97 percent of this  huge amount is sea water，or salt water．Man can only drink and use the other 3 percent--the flesh water from rivers，lakes，underground，and other sources．And we cannot even use all of that．because some of it is in the form of icebergs(冰山)and glaciers(冰河)．Even worse，some of it has been polluted．

    However，as things stand today，this small amount of fresh water is still enough for us．But  our need for water is increasing rapidly--almost day by day．Only if we take steps to deal with  this problem now can we avoid a serious worldwide water shortage later on．

    We all have to learn how to stop wasting our valuable water．One of the first steps is to develop ways of reusing it．

    Today in most large cities．water is used only once and then sent out into a sewer(下水道)  system．From there it returns to the sea or runs into underground storage tanks．But it is possible  to pipe used water to a purifying plant(净化工厂)．There it can be treated with chemicals so that  it can be used again，just as if it were fresh from a spring．

    But even if every large city purified and reused its water，we still would not have enough．All    we’d have to do to make use of the vast reserves of sea water in the world is to remove(去除)the    salt．

    If we take these steps we’ll be in no danger of drying up．

1．Which of the following statements is NOT true?

    A．As things remain unchanging，this small amount of fresh water is still enough for us．

    B．Our need for water is becoming larger and larger．

    C．There will be no water shortage in the future．

    D．We should take steps to deal with the water shortage problem．

2．To reuse water，we should         ．

    A．treat it with chemicals           B．use it only Once

    C．send it out into a sewer system    D．make it flow into underground tanks

3．In order to have enough water，we should also make use of       ．

    A．icebergs and glaciers                  B．sea water

    C．rivers and lakes                                   D．underground water

    Computers call injure(伤害)you．Most other injuries happen suddenly．For example，if you fall off a bike and break your arms，it happens very quickly．But computer injuries happen slowly．

    You probably know how to ride a bike safely．Now learn to use a computer safely．

    Your eyes 

    Too much light can injure your eyes，so never sit too close to a computer screen．Your eyes should be at least 50 centimeters(厘米)from the screen．Remember to look away from it sometimes．This gives your eyes a rest．

    When you use a computer，the window should be on your left or your right．If it is behind you，the light will reflect on(反射)the screen．If the window is in front of you，the sun and the screen will both shine into your eyes．

    Your hands and wrists

    Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times．If you use a keyboard for a long time。follow these three rules：1)You’re your wrists on something．2)Keep your elbows(肘)at the same height as the keyboard．3)Stop sometimes and exercise your hands，wrists and fingers in a different way．

    Your back

    Some people sit for many hours in front of a computer．If you sit in the wrong way．you can injure your back or your neck．So you should sit with your back straight．The top part of the screen should be in front of your eyes．Your forearms，wrists，hands and the upper part of your legs should all be parallel(平行)to the floor．If you are sitting for a long time，get up every 30 minutes and exercise your arms，legs and neck．

    Enjoy your computer，but use it safely．

    Trees are one of the oldest“citizens(公民)”of our Earth．They keep our air clean,。Reduce noise pollution，improve water quality(质量)and provide food and building materials．

    Just like us, trees change a lot as they grow．At one to three years old, young trees learn how to protect themselves．For example，many trees grow thorns(刺)to warn animals not to go near. Most young trees have large，deep green leaves so that they can catch enough sunlight and change it into their food and energy.

    当小树成长到四年的时候，它们成长可是加速并且进一步强壮，以足以面对未来生命中的挑战At the age of l5，trees become young adults．They grow more slowly and begin to produce flowers and fruit．

    It is not until山e tree is 20 to 25 years old that it becomes a real adult. The tree reaches its 1argest．Not only does the adult tree give us shade，oxygen(氧气)and natural beauty；it is also a great place for a tree house，or a place for us to nap，read a book，listen to music or sip(小口喝)tea．If we give the adult tree proper care，it will continue to live healthily for many years.

    Gradually(渐渐地)，trees begin to grow older and older and even die．At this time，they still have their important place in nature．When a tree becomes hollow(空心的)or part of it becomes dead．it provides a home to small animals and is a source of food for many other animals.

    In many ways．the life of a tree is similar(相似的)to our own life experience. When we are looking at the life of a tree , we learn about that each period of life brings its own form of joy and challenge．Enjoy every minute of the life of the trees and take care of the trees!
