See through an animal’s eyes
When does a dear blue sky not look blue When viewed through the eyes of birds, who see it in a purplish hue. Similarly, a rainbow, a caterpillar, and many other things look different to a honeybee than they do to a person because of the insect's ability to see kinds of lights that humans can't. For the first time, people can experience these unique color schemes and perspectives, thanks to a new camera system.
Humans have three types of cells (microscopic units that make up all living things) in their eyes. The cells used for vision, called photoreceptors, are cone shaped. Their job is to capture light and send it to the brain to form pictures. With their photoreceptors, humans are usually able to detect waves of green, red, and blue light- -what is known as "visible light." These waves combine into millions of distinct colors.
Animals, by contrast, can have different combinations of four or even five photoreceptors, including one that can see ultraviolet(UV) light. That means each animal will see its own set of colors in the world around it. To humans, the sky seems blue because we can't see all the UV light in it. But animals that can see UV light- including many birds, honeybees, reptiles, and some bony fish species - -would look up and see a purple sky. A butterfly that appears yellow to us would be purple and magenta to a bird.
To capture what other species can see, a research team developed a portable device that is capable of splitting light into two beams. (One is UV, and the other is the type visible to humans.) Inside the device are one standard camera and another that is sensitive to UV light. Working together, the two cameras can record high-quality video of moving objects outdoors, including both ranges of light. Software then merges the two videos to produce footage that shows what animals see.
The researchers hope the tool will provide a new perspective on the lives and behavior of certain animal species. The videos could be helpful for conservation as well. For example, they may be able to help researchers develop windows that are safe for birds.
Which of the following statements is TRUE according to the passage
A The sky is purple for all animals.
B Butterflies are yellow to birds.
C Honeybees can see UV light.
D The sky is blue because of the UV light.
What is the main purpose of the new camera system developed by the research team
A To help researchers develop safe windows for birds.
B To provide a new perspective on animal behavior.
C To conserve animal species.
D To study the sense of sight in animals.
Which of the following is NOT mentioned in the passage
A The sky appears blue because humans can't see UV light.
B Birds see the sky in a purplish hue.
C Honeybees have five eyes.
D The passage mentions a caterpillar looking different to a honeybee.
What is the role of software in the camera system developed by the research team
A It develops safe windows for birds.
B It records high-quality video of moving objects outdoors.
C It helps researchers study the sense of sight in animals.
D It merges the two videos to produce footage that shows what animals see.

2.长难句：
"Similarly, a rainbow, a caterpillar, and many other things look different to a honeybee than they do to a person because of the insect's ability to see kinds of lights that humans can't."
- 同样，彩虹、毛毛虫以及其他许多东西，从蜜蜂的眼睛里看起来的样子和从人的眼睛里看起来是不同的，因为昆虫能够看到人类无法看到的光的种类。
"With their photoreceptors, humans are usually able to detect waves of green, red, and blue light- -what is known as "visible light."
凭借它们的感光细胞，人类通常能够检测到绿、红、蓝三种光波——这被称为“可见光”。
"But animals that can see UV light- including many birds, honeybees, reptiles, and some bony fish species - -would look up and see a purple sky. "
- 但是能看见紫外线的动物——包括许多鸟类、蜜蜂、爬行动物以及一些骨鱼类——如果抬头看，会看到一个紫色的天空。
To capture what other species can see, a research team developed a portable device that is capable of splitting light into two beams. (One is UV, and the other is the type visible to humans.)
- 为了捕捉其他物种所能看到的东西，一个研究团队开发了一个便携式设备，能够将光分成两束（一束是紫外线，另一束是人类可见的光）。

The five senses of animals
Cows have a special sense. Animals have five senses that humans lack. Dolphins, whales, and bats use echolocation to locate prey and obstacles with sound waves. Sharks, rays, and some fish hunt prey even when they can't see well. They use electroreception to detect nerve and musde activity in other animals. Cold-blooded animals like bullfrogs, mosquitoes, and goldfish can see infrared light, which is invisible to humans. Sea turtles, cows, and butterflies use magnetoreception to figure out where they are by sensing Earth's magnetic field(blanket of energy around the planet). With polarized light vision, honeybees, crickets, and certain fish can see through a glare from the Sun, which helps them hunt, navigate, and communicate.
参考译文：
动物的五种感觉：
牛有特殊的感觉。动物有五种人类所不具备的感觉。海豚、鲸鱼和蝙蝠使用回声定位，通过声波来确定猎物和障碍物。鲨鱼、鳐鱼和一些鱼类在视觉不佳时也能捕猎，它们使用电感受性来检测其他动物的神经和肌肉活动。冷血动物，如牛蛙、蚊子和金鱼，能够看到红外线，这对人类是不可见的。海龟、牛和蝴蝶使用磁感应性来判断自己的位置，通过感应地球的磁场（围绕地球的能量毯）。通过偏振光视觉，蜜蜂、蟋蟀和某些鱼类能够穿透来自太阳的炫光，这有助于它们捕猎、导航和沟通。
答案详解：
Question 1: 答案：C
解释：文章提到“动物...包括一种能看见紫外线的。这意味着每个动物都会看到它们周围世界的自己的颜色组合。”这表明蜜蜂和其他动物一样，能够看到紫外线，所以选项C是正确的。
Question 2: 答案：B
解释：文章提到“研究人员希望这个工具能够为某些动物物种的生活和行为提供新的视角。”这表明相机系统的主要目的是提供关于动物行为的新的视角，所以选项B是正确的。
Question 3: 答案：D
解释：文章没有提到毛毛虫对蜜蜂来说看起来是什么样子。它只说了“彩虹、毛毛虫和许多其他事物对蜜蜂来说看起来与对人不同。”没有具体提到毛毛虫对蜜蜂的视觉影响，所以选项D是正确的。
Question 4: 答案：D
解释：文章解释说“软件随后将两个视频合并，产生显示动物所看到内容的视频。”这表明软件的作用是将两个视频合并，从而产生一个显示动物所看到的内容的视频，所以选项D是正确的。
