If you are writing or studying, it makes much difference where the light comes from. People use 46 and pens every day. They have to be very careful about the way of the light because the light shines on their work.
Every 47 gets its light either from daylight 48 the window 49 from the lamps or electricity, 50 no matter what kind of light it is, the way it shines towards our books or work is very important to the eyes.
Take a book and sit with your 51 toward the window, and try to read. Your shadow(影子) falls all over the page and makes it 52 for your eyes as if you were in a 53 room.
Now turn around and face the window. The page is 54 shadow again, while the bright light is in your eyes.
Try sitting with your 55 side toward the window. This is very good for 56 , but if you were writing, the shadow 57 fall across the page and bother you 58 .
There is another way – sit 59 your left side to the window. Now everything is perfect for writing as well.
Whatever kind of light is in the room, the rule about the right way to sit is 60 the same.
