　　He may think that red,orange and yellow are all shades of green.Sometimes a person cannot tell the difference between blue and green.In rare cases an unlucky man may see everything in shades of green—a strange world indeed.
　　In certain occupations colour blindness can be dangerous and candidates are tested most carefully.For example,when fighting at night,soldiers use lights of flares to signal to each other.A green light may mean"Advance"and a red light may mean"Danger!Keep back!",You can see what will happen if somebody thinks that red is green!Colour blindness in human beings is a strange thing to explain.In a single eye there are millions of very small things called"cones",These help to see in a bright light and to tell the difference between colours.There are also millions of"rods"but these are used for seeing when it is nearly dark.They show us shape but not colour.Wait until it is dark tonight,then go outside.Look round you and try to see what colors you can recognize.
　　Birds and animals which hunt at night have eyes which contain few or no cones at all,so they cannot see colours.As far as we know,bats and adult owls cannot see colours at all only light and dark shapes.Similarly cats and dogs cannot see colours as well as we can.
　　Insects can see ultra violet rays which are invisible to us,and some of them can even see Xrays.The wings of a moth may seem grey and dull to us,but to insects they may appear beautiful,showing colours which we cannot see.Scientists know that there are other colours around us which insects can see but which we cannot see.Some insects have favorite colours.Mosquitoes like blue,but do not like yellow.A red light will not attract insects but a blue lamp will.
　　1、According to the passage,dogs and cats.
　　A.as well as human beings can not see some colours
　　B.have fewer cones than human beings
　　C.have less rods than human beings
　　D.can see colours as well as human beings
　　参考答案：B
　　参考解析：这是道推断题，文章第四段最后一句说，猫和狗识别颜色的能力不如人类，而前文又说了不能识别颜色是因为椎状细胞少，由此，我们可以推出猫和狗的椎状细胞不如人类多。这里易误选的是A答案，注意文中的as well as是不如……好的意思，是比较级的as...as形式，不是作为“也”意思讲的短语"as well as"。
　　2、Among people who suffer from colour blindness.
　　A.some may see everything in shades of green
　　B.few can tell the difference between blue and green
　　C.few may think that red,orange and yellow are all shades of green
　　D.very few may think that everything in the world is in green
　　参考答案：D
　　参考解析：在第一段最后一句中作者说在罕见的病例中，不幸的患者会把每一种色彩都当作是深浅不同的绿色。A、B、C的错误之处都在于对色盲人数多少的限定词some或few不够准确。
　　3、Which of the following is not true about insects?
　　A.Insects can see more colours than human beings.
　　B.Insects can see ultra violet rays which are invisible to men.
　　C.All insects have their favorite colours.
　　D.The world is more colorful to insects than to human beings.
　　参考答案：C
　　参考解析：关于昆虫的讲述在文中的最后两段中，从这两段的叙述中，我们知道，昆虫能看到许多我们人类看不见的颜色，它们所看到紫外线和X射线，这里在讲到昆虫用的是表示类别的复数形式"insects"，代表的是所有的昆虫共有的特征，所以A、B、D的内容都是正确的，C的内容说所有的昆虫都有它们自己喜爱的颜色，而文中说的是一些昆虫有自己喜爱的颜色，所以C的内容不对，答案为C。
　　4、According to the passage,bats and adult owls cannot see colours.
　　A.because they hunt at night
　　B.because they cannot see light
　　C.because they have no cones and rods
　　D.because they have no cones
　　参考答案：D
　　参考解析：这道题可从第四段第一二句中找到答案，这两句告诉我们在夜晚捕食的鸟和动物的眼睛几乎没有或根本没有锥状细胞(cone)，所以不能区别颜色。而蝙蝠或猫头鹰就属于这样的动物。故D正确。
　　5、When millions of rods in our eyes are at work in darkness we can see.
　　A.colours only
　　B.shapes and colours
　　C.shapes only
　　D.darkness only
　　参考答案：C
　　参考解析：这道细节题可以"rods"这个专业词汇帮助我们在第三段中间位置迅速定位，在这里，作者告诉我们视杆细胞(rod)在天色接近黑暗时发挥作用，他们能使我们看到物体的外形，而不是颜色。故选C。
　　参考译文：
　　大约每百个男人中就有十个在某种程度上患有色盲，而女性幸运的只有大约每二百个中就有一个受到这种影响。色盲有不同的形式。男人可能看不见深红色。
　　他可能会认为红色、橙色和黄色都是绿色的色调。有时一个人无法分辨蓝色和绿色的区别。在极少数情况下，不幸的人可能看到绿色的色调，这的确是一个奇怪的世界。
　　在某些职业中，色盲是危险的，应征者要经过最仔细的检验。例如，在夜间作战时，士兵们用火光互相发信号。绿灯可能意味着“前进”，红灯可能意味着“危险”。往后退！”如果有人认为红色是绿色，你会看到会发生什么！人类的色盲是一种奇怪的现象。在一只眼睛里有数以百万计的叫做“锥体”的非常小的东西，这些东西有助于在明亮的光线下看东西并区分颜色。也有数以百万计的“棒”，但这些东西用于在接近黑暗的时候看东西。它们显示形状，但不显示颜色。等待直到它变暗。今晚去方舟，然后到外面去。看看四周，看看你能辨认出什么颜色。
　　夜间捕猎的鸟类和动物眼睛里几乎没有或根本没有锥体，因此它们看不见颜色。据我们所知，蝙蝠和成年猫头鹰根本看不见颜色，只看到亮和暗的形状。同样，猫和狗也看不见颜色。
　　昆虫能看见我们看不见的紫外线，有些甚至能看到X射线。蛾子的翅膀在我们看来可能灰暗无光，但对于昆虫来说，它们可能看起来很漂亮，呈现出我们看不见的颜色。科学家们知道，我们周围还有昆虫能看见但看不见的其他颜色。有些昆虫很喜欢。喜欢颜色。蚊子喜欢蓝色，但不喜欢黄色。红灯不会吸引昆虫，但蓝灯会。
