Look! There are four butterflies in the garden. One is red, one is yellow, one is green, and the other one is white. They play games and dance together every day, and they are very happy. One day, it’s fine. Four butterflies are playing a game in the garden. Suddenly it is full of dark clouds and it begins to rain hard.
1. GB: Oh, it’s raining hard. Green Tree is over there. She can help us.
GB: Green Tree, our wings are wet. Please let us stay under your leaves.
GT: Green Butterfly, I like you. We have the same color. You can come in, but the other three butterflies must go away.
GB: No, thank you. We are good friends. We love each other and must stay together.
RB: Rose is over there. She can help us.
2. RB: Rose, our wings are wet. Please let us stay under your leaves.
R: Red Butterfly, I like you. We have the same color. You can come in, but the other three butterflies must go away.

The sun drives the clouds away and asks the rain to stop. Soon the sun gives off bright light and
dries up their wings.

| No one knows when the first house was built and who was the first one to built the house. But the houses are changing all the time. ( )1. What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects (建筑学家) believe that they may come true one day. The only thing for sure is the houses will be as green as possible in the future. ( )2. Many architects in the world would like to build a house like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even make fresh air for the room. The"root"(根) of the house is deep under the ground. It uses the soil to control the room's temperature. ( )3. Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it's in the bright sun, the cover of the house will turn white to protect it from strong heat. During dark days, it turns dark and takes in as much light and heat as possible to produce energy. ( )4. This design is perhaps for the future of food. It has a garden on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every morning, you just need to walk outside and collect your meals. ( )5. Looking to the future isn't the only way to be green. Sometimes, the old ways of building houses can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier for hot air to run out of the chimney. | |

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

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？

s
only one color when the sun rises and falls.

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.
