题目内容
3.You can not 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 examples that can be seen by their own light.Such things are luminous.Most of the things you see are not giving off light of their own.They are simply reflecting(反射) light that falls on them from the sun or some other luminous bodies.The moon,for example,does not give off any light of its own.It is non-luminous.You see it because sunlight falls on it and some of it reflects in our direction.So moon light is only second hand sunlight.When you look at a book,it sends to your eyes some of the light which falls on it,and you see the book.If light could be kept out from where you are so that there would be no light fro the book to reflect,then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all.Light reaches us from the moon,which is about 380 000kilometers away,in only a little more than a second.
25.You can see the book becauseD.
A.your eyes are close to it
B.your eyesight can get to it
C.it has light of its own
D.it reflects some of the light
26.The underlined word"luminous"meansC.
A.visible(可见的)
B.all colors
C.giving off light
D.sunlight
27.Which of the following is true?D
A.All the things you can see give off light.
B.Light from the book is much shorter than that from the moon.
C.Light travels so fast that there is no time for you to read.
D.The moment you open your eyes the light from the book travels to your eyes.
分析 这是一篇科普类的阅读理解,包含介绍科学知识、社会知识等.本文主要介绍光线的原理,以及人们为什么能够看见物体?是因为物体能够反射光线.
解答 25 D 细节理解题; 从文章的第一段的句子:You can not see any object unless light from that object gets into your eyes你不能看到任何对象,除非从对象的光进入你的眼睛:文章第二段第一行When you look at a book,it sends to your eyes some of the light which falls on it,and you see the book.可知书本反射光线是人看清书的主要原因.故推测:光线反射到我们的眼睛才能看见东西.同时本题也可以视为同义句的相互转换.
26 C 词义理解题;根据前文The sun,the stars,a lighted lamp are examples that can be seen by their own light太阳、星星、一盏灯都是他们自己的光可以看到的例子.Such things 指的是太阳、星星、一盏灯可以发光的东西,故推测答案为C.give off light 散发光,热,线等.
27 D 推理题:从最后一段的Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all光传播得如此之快,以至于它从你读到的那本书中读到的时间是如此短暂,仿佛根本就没有时间.说明光的速度很快,你一睁开眼,光线就到你眼中了.故推测正确答案选D.
