第10题：
Every house gets its light either from daylight through the windows--which is the 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 turnaround and face the window.The page is in the shadow again,while the bright light is in your eyes.
Try sitting with your right 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 of light is in the room,the rule about the right to sit is always the same.
Which of the following is true?
B.The way the light shines on your work makes no difference.
C.We needn't care about where the light comes from.
D.People can write or study under a light that comes from any direction.
