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.
【小题1】You can see the book because________.
【小题2】The Chinese meaning of the world“luminous”is close to_______.
【小题3】________has light of its own.
【小题4】Light travels about_________kilometers per second.
【小题5】Which of the following is TRUE?

“Haibao,the mascot(吉祥物)of the 2010 Shanghai World Expo,is very cute,”said Gu Hui,a school kid.“I want a big toy like the mascot.”
Haibao looks like the Chinese word ren,which means people or a person.The name,a typical lucky one in Chinese tradition comes from the Chinese phrase “Si Hai Zhi Bao” —the treasure of the four seas.It also means the treasure of Shanghai,which lies beside the sea.
Haibao’s blue curly(卷曲的)hair looks like the waves of the sea.Its smile is a sign of the healthy spirit of China.Those thumbs-up(翘拇指)will welcome millions of people to Shanghai from around the world.Its big feet show China has the ability to host a successful Expo.
Haibao was created by two artists,one from the mainland(大陆) and the other from Taiwan.The design is about people living together in the city.The designers want it to fit the theme of the Shanghai Expo,that is,a good life should be created by all the people and people should have harmonious relationships(和谐关系) with nature and society,so that life in cities would be better.
Surely the mascot will become the lucky symbol and cultural remark of Shanghai Expo.
