Question

【題目】 Butterflies are some of the most beautiful insects in the world. However, what interests the scientists most is not their fascinating looks, but how they sense nature. They use their senses of sight, touch, hearing, smell and taste to find food, lay eggs in good places and avoid hungry enemies.

Butterflies have large compound(復(fù)合的) eyes. No matter where the things are, they can see them without turning their heads. 【1】 They are more possible to notice a sea of flowers than a single plant. Butterflies do not "see” colors. They are color blind. 【2】The light on many flowers guides butterflies to honey.

How do butterflies smell? Butterflies have a very well-developed sense of smell, but it is not in their noses, since they don't have one. Sense organs (器官)are in their feet, and many other parts of the body.【3】

Do butterflies use their mouths to taste the food they find? Not really. Butterflies' feet have sense organs that can taste the sugar in flower honey. They let the butterflies know if there is something delicious. 【4】They feed their babies using a long tube(管道)，and they get all their food from this tube as well.

Butterflies don't have ears. Instead, they “hear" sounds through their wings by sensing changes in sound vibrations(震動).Butterflies' body is covered with sensory hairs. 【5】.For example, the hairs give butterflies information about the wind when they're flying. And where there is rain, the hairs can also tell butterflies.

The scientists say that butterflies may have senses we don't even know about yet, because their body is very different from ours. Therefore, it is difficult to understand when we use our own human senses to study it.

A. Like most insects, butterflies are very nearsighted.

B. They can let butterflies feel the environment around.

C. So it is not difficult for butterflies to find flower honey.

D. But they can sense sunlight, which tells them the direction.

E. They can help butterflies find their favorite flower honey food.

F. Some female butterflies taste the plants carefully to find places to lay eggs.

【解析】

本篇是科普文章。介紹蝴蝶的各種感覺，包括每種感覺器官的功能和作用。蝴蝶有復(fù)眼，但非常近視�？床坏筋伾�但可以感知陽光；嗅覺非常靈敏，感覺器官在它們的腳和身體的許多其他部位；它們用一根長管獲取食物和喂養(yǎng)他們的孩子；沒有耳朵，它們通過翅膀感知聲音振動的變化�？茖W(xué)家說蝴蝶可能有我們還不知道的感覺。

【1】根據(jù)下文“They are more possible to notice a sea of flowers than a single plant.”—— 他們更可能注意到花海而不是單一的植物，推斷 “蝴蝶看不清單一的植物，是近視眼”；故選A。

【2】上文“Butterflies do not "see” colors. They are color blind.”，可知“蝴蝶是色盲”，下文“The light on many flowers guides butterflies to honey. ”——許多花上的光引導(dǎo)蝴蝶采蜜；根據(jù)文句表達(dá)的邏輯順序，推斷空格指“蝴蝶能感覺到陽光”，故選D。

【3】空格上文介紹蝴蝶在腳上和身上的其它地方有敏感的感覺器官；根據(jù)文句表達(dá)的邏輯關(guān)系，推斷空格陳述“這些能幫蝴蝶做什么”；故選E。

【4】根據(jù)下文“They feed their babies using a long tube(管道)，and they get all their food from this tube as well. ”，可知“它們用一根長管獲取食物和喂養(yǎng)他們的孩子”；空格根據(jù)文句表達(dá)的邏輯關(guān)系，推斷空格是介紹“蝴蝶產(chǎn)卵”；故選F。

【5】上文“Butterflies' body is covered with sensory hairs” 蝴蝶的身體上長滿了有感覺的毛，推斷下文是介紹“sensory hairs的作用，可以讓蝴蝶感知周邊的世界”；故選B。

選句子完成短文，解答前先閱讀備選句，理解備選句的句意；再跳空閱讀全文，了解大意；然后，根據(jù)上下文聯(lián)系推斷空格所缺的信息，本篇解答時要根據(jù)介紹蝴蝶的“視覺、觸覺、聽覺、嗅覺和知覺”線索推斷空格的信息。
