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 turn around 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(打撹)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

Although photography (the Greek word for "writing with

that we take them for granted, they are relative recent inventions. 【1】______
From the time of the Renaissance, many artists had used the
CAMERA OBSCURA draw forms and linear perspective accurately. 【2】______
A camera obscura was a dark room or box With light entering in a 【3】______
tiny hole, perhaps focused on by a lens. An inverted image from the 【4】______

the nineteenth century that several researchers working independent 【6】______
of each other found ways to capture this image permanently.

to lead to “movies.” In the mid-twentieth century, the technology 【8】______
of capturing moving images from the world had evolved wireless 【9】______

the world that we see.

What I remember now about VE Day was the afternoon and the evening. It was a fine May day. I remember coming home at about five o'clock. My father and mother came in about an hour later. After dinner I said I wanted to see the bonfire (篝火), so when it got dark my father took me to the end of the street. The bonfire was very high, and some peo-ple had collected some old clothes to dress the unmistakable figure with the moustache (小胡子) they had put on top of it. Just as we arrived, they set light to it. The flames rose and soon covered the "guy." Everyone was cheering and shouting, and an old woman came out of her house with two chairs and threw them on the fire to keep the fire going.
I stood beside my father until the fire started to go down, not knowing what to say. He said nothing either. He had fought in the First World War and may have been remem-bering the end of that. At last he said, "Well, that's it, son. Let's hope that this time it really will be the last one. "
Where did the narrator live before the Second World War？
A．In a small city.
B．In London.
C．In Europe.
D．In the countryside.
There are many problems in our modern world. One very serious problem is energy. We get a great 【71】 of energy we need from coal, gas, and oil.

All of the new methods 【79】 scientists are finding are still very expensive, but perhaps they will help solve our energy problems 【80】 the future.
