完成下列各题A

If you are writing or studyin9，it makes very much difference where the light comes from．People who use books and pens every day have to be especially careful about the way the light shines on their work．

Every house gets i ts light either from daylight through the windows--which is the very best to use--or from lamps or electricity：but whichever kind of light it is，the way it shines toward our book or work is a matter of great importance to the eyes．

Take a book．sit with your back toward the window，and try to read．Your shadow(影子) falls all over the page and makes it almost as bad for your eyes as if you were in a dark room．

Now turn around and face the window．The page is in the shadow again，while the bright light is in your eyes．

Try sitting with you fight side toward the window．This is very well for reading，but if you were writing．the shadow of your hand would fall across the page and bother(打搅)you a little．   

There is just one other way：sit with your left side to the window．Now everything is perfect for reading and for writing，too．

Whatever kind oi light is in the room，the rule about the right to sit is always the same．

Which of the following is true?

Forty—thousand of the world’   s young children die every day．Many of these deaths can be prevented．In fact，experts say，techniques now exist to save the lives of half of these children．The techniques are medically effective(有效的)，simple to use and low cost.The biggest task has been to inform. parents about these life-saving techniques．

Diarrhea(腹泻)is the main cause of death among children in developing countries．Diarrhea results when the body tries to clear itself of harmful bacteria(细菌)．The body does this by getting our liquids，sometimes uncontrollably．If too much water，sugar and salt ale lost in this way，the body cannot work normally．The child may die．   

The Uni ted Nations International Children’s Fund，UNICF，introduces a technique．It uses a simple mixture of sugar and salt in water．The mixture does not stop diarrhea．But if used often as needed，it keeps fluid(体液)levels normal until the body has fought off the harmful bacteria．

In Egypt，for example，the treatment was used in a children’s health care program in the province of Alexandria．It reduced by one—half the number of deaths caused by diarrhea.The technique has now been used throughout the country．
