Question

【題目】 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(視力) is special in all kinds of ways.

	Dogs have fewer color-detecting cells (色彩感知細胞) 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 (紫外線), 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 (敵人). 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.

文章大意：這是一篇說明文，短文主要講述了四種動物：狗、跳蛛、老鼠和馬，分別說明了四種動物的生活習性——視力。狗這種動物無法看見很多顏色，能看見藍色、棕色和黃色物體，他們的色彩感知細胞比人類弱。跳蛛有八雙眼睛，他們能看見更多的顏色，還能看見紫外線，比人類看得更清楚。老鼠大多數(shù)時間在晚上出來活動，能用一只眼睛走路，一只眼睛觀察他們的敵人。馬的眼睛在他們頭部的兩邊，所以他們的視野更寬闊，可是鼻子前面有盲點，他們能看見綠色和藍色物體，但是大多數(shù)時間他們只看見灰色物體。

【1】細節(jié)理解題。根據(jù)Dogs have fewer color-detecting cells than us and they can only see blue, brown and yellow. 狗的顏色探測細胞比我們少，它們只能看到藍色、棕色和黃色。可知，當你穿著黃色或藍色的衣服時，你的狗會更容易跟著你，是因為狗只能看到黃色、藍色和棕色；故答案為B。

【2】細節(jié)理解題。根據(jù)Mice can move one eye in different directions while keeping the other eye still. 老鼠可以朝不同方向移動一只眼睛，同時保持另一只眼睛不動。可知，老鼠可以自由地移動一只眼睛，而保持另一只眼睛不動；故答案為C。

【3】理解歸納題。根據(jù)Dogs have fewer color-detecting cells than us and they can only see blue, brown and yellow. 狗的顏色探測細胞比我們少，它們只能看到藍色、棕色和黃色。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動一只眼睛，同時保持另一只眼睛不動。…它們看不到我們那么多的顏色。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，馬的鼻子前面有一個盲點。它們可以看到綠色和藍色，但大多數(shù)時候它們看到的是灰色�？芍�，狗、老鼠、馬看到的顏色都比人類少，所以應是三種，故答案為C。

【4】主旨大意題。根據(jù)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. 我們眼中的世界是如此的豐富多彩。動物過著與我們人類不同的生活。它們有不同的需求，……所以它們的視力在各個方面都很特別。聯(lián)系下文的描述，可知本文主要告訴我們動物看世界的特殊方式是因為它們的需要，故答案為D。
