Question

【题目】 The world is so colorful in our eyes. But does it look the same through the eyes of animals?

Animals live a different life from us humans. They have different needs. So their eyesight(视力) is special in all kinds of ways.

	Dogs have fewer color-detecting cells (色彩感知细胞) than us and they can only see blue, brown and yellow. So when you go out with your pet dog, you’d better wear blue or yellow clothes so that your dog can follow you more easily.
	Jumping spiders have eight pairs of eyes and they can see more colors than humans. Not only that, they can see ultraviolet light (紫外线), so they will see things clearer than us.
	Mice can move one eye in different directions while keeping the other eye still. It’s better to see their enemies (敌人). They can’t see as many colors as us. It’s not necessary because they mostly come out at night.
	Horses are very tall and their eyes are on either side of the heads, so they can see wider than humans. However, a horse has a blind point in front of its nose. They can see green and blue, but most of the time they see grey.

【4】D

【解析】

文章大意：这是一篇说明文，短文主要讲述了四种动物：狗、跳蛛、老鼠和马，分别说明了四种动物的生活习性——视力。狗这种动物无法看见很多颜色，能看见蓝色、棕色和黄色物体，他们的色彩感知细胞比人类弱。跳蛛有八双眼睛，他们能看见更多的颜色，还能看见紫外线，比人类看得更清楚。老鼠大多数时间在晚上出来活动，能用一只眼睛走路，一只眼睛观察他们的敌人。马的眼睛在他们头部的两边，所以他们的视野更宽阔，可是鼻子前面有盲点，他们能看见绿色和蓝色物体，但是大多数时间他们只看见灰色物体。

【1】细节理解题。根据Dogs have fewer color-detecting cells than us and they can only see blue, brown and yellow. 狗的颜色探测细胞比我们少，它们只能看到蓝色、棕色和黄色。可知，当你穿着黄色或蓝色的衣服时，你的狗会更容易跟着你，是因为狗只能看到黄色、蓝色和棕色；故答案为B。

【2】细节理解题。根据Mice can move one eye in different directions while keeping the other eye still. 老鼠可以朝不同方向移动一只眼睛，同时保持另一只眼睛不动。可知，老鼠可以自由地移动一只眼睛，而保持另一只眼睛不动；故答案为C。

【3】理解归纳题。根据Dogs have fewer color-detecting cells than us and they can only see blue, brown and yellow. 狗的颜色探测细胞比我们少，它们只能看到蓝色、棕色和黄色。Mice can move one eye in different directions while keeping the other eye still. …They can’t see as many colors as us. 老鼠可以朝不同方向移动一只眼睛，同时保持另一只眼睛不动。…它们看不到我们那么多的颜色。以及However, a horse has a blind point in front of its nose. They can see green and blue, but most of the time they see grey. 然而，马的鼻子前面有一个盲点。它们可以看到绿色和蓝色，但大多数时候它们看到的是灰色。可知，狗、老鼠、马看到的颜色都比人类少，所以应是三种，故答案为C。

【4】主旨大意题。根据The world is so colorful in our eyes. ……Animals live a different life from us humans. They have different needs. So their eyesight is special in all kinds of ways. 我们眼中的世界是如此的丰富多彩。动物过着与我们人类不同的生活。它们有不同的需求，……所以它们的视力在各个方面都很特别。联系下文的描述，可知本文主要告诉我们动物看世界的特殊方式是因为它们的需要，故答案为D。
