  It was so dark outside the car window that is was hard to see anything.

  “Can I have a carrot, Mum?” Riley asked.

  “I don't have any carrots,” her mum said.“How about an apple?”

  “No,” said Riley.“It has to be a carrot.”

  “Why do you want a carrot?” asked her mum.

  “You always say carrots help your eyes,” said Riley.“If I eat one now, it might help me see in the dark.”

  Would eating a carrot really help Riley? What is special about carrots? A clue to what makes a carrot special is its color.Carrots are orange because they store beta-carotene(胡萝卜素).Beta-carotene is a way to talk about Vitamin A(维生素A).Your eyes need Vitamin A.It helps them work.

  When light hits your eye, very small parts inside turn the light into messages.The messages go to your brain(脑),and then you know what you're looking at.Your eye can only turn light into messages when it has a special chemical(化学物质).That's where Vitamin A comes in.Your eyes use Vitamin A to make the special chemical.Every time your eye changes light to messages, a little bit of the chemical is used up.By the end of the day, you've looked at hundreds of things.That uses up a lot of the chemical.Your eyes need to make more.

  What should you eat if you don't like carrots? Don't worry.Other fruits and vegetables have Vitamin A too.The secret is in their color.Most orange or red fruits store some beta-carotene, or Vitamin A.Sweet potatoes, red peppers, mangoes(芒果)are a few that have the same orange secret.Can you think of any more?

What is the sky? Where is it? How bright is it? What lies above it? These questions are difficult to answer, aren’t they?

  Is the sky blue? The sky has no color. We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can’t fly very high because the air gets thinner when they go up higher. If we go up about 1,200 kilometers from the earth, we’ll find no air there.

  When we talk about the sky, we usually mean the atmosphere around the earth. It is like a very thick “cover” over the earth and keeps it warm. Without the “cover”, the earth would be a very cold place and nothing could live on it.

  Looking up above us, you will see the blue sky with white clouds. It is usually light blue, but the sky would be dark blue if you go to the top of the highest mountains. And you will see fewer clouds between you and the sun.

  And if you sit in a spaceship high above the earth, there is no air at all. The sky would be so dark that its color would be black.

  Sometimes the sky doesn’t look blue. When the sun rises and falls, you will see red, orange, and other colors in the sky. These are the most beautiful moments of the day.

  Now you may understand that we see colors because the air scatters (散射) the sunlight. Light travels through the air. Without air, there would be no light and no colors.

1.Planes can’t fly very high because ____________.

A.there is air around the world

B.the air gets thinner when they go up higher

C.it’s warmer in the sky

D.the air gets thicker when they go up higher

2.We can see colors of the sky because ____________.

A.the sun rises and falls every day

B.the sky has lots of colors

C.the air scatters the sunlight

D.the sunlight has many colors

3.Which of the following is TRUE?

A.There is little air without light and colors in the sky.

B.The sky will look red, orange and other colors at noon.

C.The sky has only one color when the sun rises and falls.

D.The sky is dark blue if you go to the top of the highest mountains.

You’ve probably heard of working dogs that help police officers, or horses that help farmers. Did you know that carrier pigeons(信鸽)can be trained to help people too? Here are some examples.
Mailman
Carrier pigeons can be trained to carry messages to people. The note is placed into a small can. The can is tied to the pigeon’s leg. Then the pigeon flies off with the note.
Lifeguard
From high up in the sky, specially trained pigeons can find orange life jackets in the ocean. Sometimes it is difficult for humans to find people lost at sea, especially when the weather is bad. However, pigeons can fly quickly over a large area of water to look for people.
Spy
Many years ago, carrier pigeons were used to help our country during wars (战争). “Spy pigeons” had small cameras that were tied to their feet. As a pigeon flew over enemy (敌人)land, the camera took photos of the land below. This would allow our soldiers to see where the enemies were and what they were doing.
So next time you see a pigeon, stop and watch it closely. What might look like an ordinary bird to most people, might actually be helpful.
