It¨s important that we should take care of our eyes, otherwise we may get short-sighted.

Now take Xiao Ming for example.                            

                                     

                                     

                                     

                                      

                                      

                                      

                                        

                                       

                                       

                                        

                                      

及屈准�才衾量鄂�(慌20籾��耽弌籾1.5蛍��諾蛍30蛍)

  What is in the drug that makes you sick or dead ? For example ,cocaine is harmful ,but what makes it harmful?

  I can¨t tell you all about drugs ,but I can  36  you think about them in this  37  way. Your body is a very complicated(鹸墫議) machine,  38  a lot of chemical machinery, all of which is finally turned  39  it all works together . Special chemicals, which we call drugs ,can affect it in many different ways.

  Some drugs are  40  when your body has a problem, as with disease-causing bacteria. Then someone may give you aspirin to keep your temperature from going too  41   or some penicillin(楳湛殆)  42  it stops the growth of some kinds of bacteria.  43  ,all drugs are really poison,  44  if you take too much ,so you must always use them  45   .

  Why do some people take drugs like cocaine ? For a little while they seem to make you feel better ,or happier .But  46   their effects have  47  ,your body has to pay an extra  48  to get back to normal. That makes  you want to get  49  of the drug .

Drugs like cocaine have their special effects because they act as  50  for your nervous system. They cut off some of your nerve pathways and take away some of your senses and your  51  .They make you want always more . And just a little too much can even  52  nerves to your heart and stop its beating .

Many of us worry about the  53  around us and what pollution does to us .How about your internal(坪壓議) environment, and what goes on  54  you ? You control that all by yourself in what you put into your  55  . Most drugs are pollutants .You would not want pollutants in the air and water around you . Why would you want pollutants in your body ?
