     About ten men in every hundred have the trouble of color blindness in some way. Women are luckier,

only about one in two hundred is affected (感染) in this matter. Perhaps, after all, it is safer to be driven

by a woman.

    There are different kinds of color blindness. For example, a man cannot see deep red. He may think

that red, orange and yellow are all shades (影子)of green. Sometimes a person can't tell the difference

between blue and green. Only a few unlucky men may see everything in shades of green-a strange world

indeed.

    Color blindness in human beings is a difficult thing to explain. In only one eye there are millions of very

small things called "cones (锥状细胞)". These help us to see in the bright light and to tell differences

between colors. There are also millions of  "rods ( 杆状细胞)", but these are used for seeing when it is

nearly dark. They show us shapes but not colors.

    Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light

will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky.

With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of

the rods we can see shapes at night.

1. "Color blindness" means "______" in Chinese.

A. 盲目    

B. 无色    

C. 色盲    

D. 讨厌颜色

2. Some people say it's safer to be driven by women because ______.

A. women drive more carefully

B. women are better at driving than men

C. women can see things more clearly

D. there are fewer color-blind women

3. With the help of the "cones", we can ______.

A. tell different shapes  

B. kill insects

C. see in the dark    

D. tell orange from yellow

4. We can attract and kill mosquitoes by using a ______ light.

C. blue    

D. green

5. Which of the following sentences about color blindness is TRUE?

B. Not all of men have the same problem in recognizing colors.

C. None of men can tell the difference between blue and green.

D. All of men see everything in shades of green.

三、

对月

月,夜愈黑,你愈亮;烟火熏不脏你,灰尘也不能污染你;你是浩浩天地间的一面高悬的镜子吗
你夜夜出来,夜夜却不尽相同;这几天圆了,过几天亏了;圆得那么丰满,亏得又如此缺陷!我明白了,月,大千世界,有了得意有了悲哀,你就全然会照了出来的。你照出来,悲哀的盼你丰满,望眼欲穿;你丰满了,却使得意的大为遗憾,因为你立即又要缺陷去了。你就是如此千年万年,陪伴了多少人啊!不管是帝王,不管是布衣,还是学士,还是村儒,得意者得意,悲哀者悲哀,先得意后悲哀,悲哀了而又得意……于是,使在这无穷无尽的变化之中统统消失了,而你却依然如此,得到了永恒!
你对于人就是那砍不断的桂树,人对于你就是那不能歇息的吴刚。吴刚是仙,可以长久,而人却要以短暂的生命付之于这种工作吗
这是一个多么奇妙的谜!从古至今,多少人万般思想,却如何不得其解。或是执迷,将便为战而死,相便为谏而亡,悲、欢、离、合,归结于生命;或是自以为觉悟,求仙问道,放纵山水,遁入空门;或是勃然而起,将你骂杀起来,说是徒为亮月,虚有朗光,只是得意时锦上添花,悲哀时火上加油,是一个面慈心狠的阴婆,是一泊平平静静而溺死人命的渊潭。
月,我知道这是冤枉了你,是曲解了你,你出现在世界,明明白白、光光亮亮;你的存在,你的本身就在说明这个世界,就在向世人作着启示:万事万物,就像你的形状,一个圆、一个圆地完成啊!试想,绕太阳运行的地球也是圆的,运行的轨道也是圆的,在小孩手中被玩弄的弹球是圆的,弹动起来也是圆的旋转。人何尝不是这样呢人再小,也要长老;人老了,却有和小孩一般的特性。老和少是圆的接榫。冬过去了是春,春种秋收后又是冬。老虎可以吃鸡,鸡可以吃虫,虫可以蚀杠子,杠子又可以打老虎。就是这么不断的否定之否定,周而复始,一次不尽然一次,一次又一次地归复着一个新的圆。
所以,我再不被失败所惑了,再不为成功所狂了,再不为老死而悲了,再不为生儿而喜了。我能知道我前生是何物所托吗能知道我死后变成何物吗活着就是一切,活着就是乐,活着也有苦,苦里也有乐;犹如一片树叶,我该生的时候,我生机勃勃地来,长我的绿,现我的形,到该落的时候了,我痛痛快快地去,让别的叶子又从我的落疤里新生。我不求生命的长寿,我却要深深地祝福我美丽的工作,踏踏实实地走完我的半圆,而为完成这个天地万物运动规律的大圆尽我的力量。
月,对着你,我还能说些什么呢你又能说些什么呢你真是一面浩浩天地间高悬的明镜,让我看见了这个世界,看见了我自己。但愿你在天地间长久,但愿我的事业永存。

文中说月亮“真是一面浩浩天地间高悬的明镜”,其理由是什么请从三个方面回答。
