You can’t see any object unless light from that object gets into your eyes.Some of the things you see give off light of their own。The sun,the stars,a lighted lamp are the examples that can be seen by their own light.But most of the things you see are not giving off light of their own.They are just reflecting(反射)light that falls on them from the sun or some other luminous bodies.The moon,for example,doesn’t give off any light of its own.It is not 1uminous.You see it because sunlight falls on it and some of the sunlight reflects on the earth.So moonlight is only second—hand sunlight.
When you look at a book,it sends some of the light which fails on it to your eyes,and you see the book.If light could be kept out from where you’re so that there would be no light from the book to reflect.Then you couldn’t see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you’re reading to your eyes is as short as if there were no time at time.Light reaches us from the moon,which is about 380,000 kilometres away,in only a little more than a second.

A.your eyes are close to itB.it reflects some of the light
C.it has light of its ownD.it is big enough to be seen

A.300,000B.100,000C.400,000D.190,000
【小题5】Which of the following is TRUE?
A.All the things you can see give off light.
B.Light from the book is much faster than that from the moon.
C.The moment you open your eyes,the light from the book travels to your eyes.

Frank Smithson woke up and got up to turn off the alarm clock(闹钟). “Oh no!” he thought to himself. “Another day at that office; a boss (老板) who shouts at me all the time.”

As Frank went downstairs, his eyes fell on a large brown envelope (信封) by the door. He was very happy when he opened it and read the letter inside. “Bigwoods Football Pools (足球赌博公司) would like to congratulate you. You have won half a million pounds(英镑).”

Frank suddenly came to life. The cigarette fell from his lips (唇) as he let out a shout that could be heard halfway down the street.

At 11:30 Frank arrived at work. “Please explain why you're so late,” his boss said. “Go and jump in the lake,” said Frank. “I've just come into a little money so this is good-bye. Find yourself someone else to shout at.”

That evening Frank was smoking a very expensive Havana cigar (雪茄) when a knock was heard on the door. He rushed to the door. Outside were two men, neatly dressed in grey suits. “Mr. Smithson,” one of them said, “we're from Bigwoods Pools. I'm afraid there's been a terrible mistake…”
