Text 3When the first white men arrived in Samoa, they found blind men, who could see well enough to describe things in detail just by holding their hands over objects. In France, Jules Roman tested hundreds of blind people and found a few who could tell the difference between light and dark. He narrowed their photosensitivity(感光灵敏度) down to areas on the nose or in the finger tips. In 1960 a medical board examined a girl in Virginia and found that, even with thick bandages over her eyes, she was able to distinguish different colours and read short sections of large print.Rosa Kuleshova, a young woman in the Urals, can see with her fingers. She is not blind, but because she grew up in a family of blind people, she learned to read Braille to help them and then went on to teach herself to do other things with her hands. She was examined by the Soviet Academy of Science, and proved to be genuine, Shaefer made an intensive study with her and found that, securely blindfolded with only her arms stuck through a screen, she could tell the difference between three primary colours. To test the possibility that the cards reflected heat differently, he heated some and cooled others without affecting her response to them. He also found that she could read newsprint under glass, so texture was giving her no clues. She was able to identify the colour and shape of patches of light projected on to her palm or on to a screen. In rigidly controlled tests, with a blindfold and a screen and a piece of card around her neck so wide that she could not see round it, Rosa read the small print in a newspaper with her elbow. And, in the most convincing demonstration of all, she repeated these things with someone standing behind her pressing hard on her eyeballs. Nobody can cheat under this pressure.31. The first white men to visit Samoa found people who ______.A) were not entirely blindB) described things by touching themC) could see with their handsD) could see when they hold out their hands

If you are writing or studying,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 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?A.How the light shines on our work is of much importance.
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.
