题目内容
【题目】 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(复合的) 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(震动).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。介绍蝴蝶的各种感觉，包括每种感觉器官的功能和作用。蝴蝶有复眼，但非常近视。看不到颜色但可以感知阳光；嗅觉非常灵敏，感觉器官在它们的脚和身体的许多其他部位；它们用一根长管获取食物和喂养他们的孩子；没有耳朵，它们通过翅膀感知声音振动的变化。科学家说蝴蝶可能有我们还不知道的感觉。
【1】根据下文“They are more possible to notice a sea of flowers than a single plant.”—— 他们更可能注意到花海而不是单一的植物，推断 “蝴蝶看不清单一的植物，是近视眼”；故选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. ”——许多花上的光引导蝴蝶采蜜；根据文句表达的逻辑顺序，推断空格指“蝴蝶能感觉到阳光”，故选D。
【3】空格上文介绍蝴蝶在脚上和身上的其它地方有敏感的感觉器官；根据文句表达的逻辑关系，推断空格陈述“这些能帮蝴蝶做什么”；故选E。
【4】根据下文“They feed their babies using a long tube(管道)，and they get all their food from this tube as well. ”，可知“它们用一根长管获取食物和喂养他们的孩子”；空格根据文句表达的逻辑关系，推断空格是介绍“蝴蝶产卵”；故选F。
【5】上文“Butterflies' body is covered with sensory hairs” 蝴蝶的身体上长满了有感觉的毛，推断下文是介绍“sensory hairs的作用，可以让蝴蝶感知周边的世界”；故选B。
选句子完成短文，解答前先阅读备选句，理解备选句的句意；再跳空阅读全文，了解大意；然后，根据上下文联系推断空格所缺的信息，本篇解答时要根据介绍蝴蝶的“视觉、触觉、听觉、嗅觉和知觉”线索推断空格的信息。
