What is the sky? How high is it? What color is it? What birds can live above it? These questions are difficult to answer, aren't they? In fact, the sky has no color. Then why does the sky look blue?

    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. That is because the air gets thinner when they go higher. The same will happen to us if we go high enough. If we go up about 1,200 kilometers from the earth, we'll find no air there. Some birds can fly into the sky as high as a plane, but they cannot fly or live without air.

    Looking up above us, you will see the blue sky with white clouds. It is usually light blue. The color would be bluer when you see on the top of a high mountain. And you will see fewer clouds in the sky between you and the sun. Sometimes the sky doesn't look blue. When the sun rises and falls, you will see red, orange and other colors in the sky, such are the most beautiful moments of the day.

    Who can see the colors of the sky high above the earth? The astronauts! They can see those beautiful colors of the sky from the outer space. However, before flying into the outer space, they sit in a spaceship high above the earth and there is no air at all. The sky would be that dark and its color would be black.

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

When 1949 meets 2023

Hi, I'm Hanhan, a student from Beijing. I was born in 2008. In the past 15 years, everyone's life changed a lot. My grandfather Jianguo feels (感觉) the same. He was born in1949. "When I was your age, life was very different," he said to me. But how was it different? I'm going to talk to him.

Jianguo: When I was born, many families were poor (贫穷的). Most people could spend only about 50 yuan a year.

Hanhan: In 2023, most people spent about 30,000 yuan a year. It increased a lot. I have some pocket money (零花钱). I use it to buy my favourite toys.

Jianguo: In 1949, about 75% of Chinese people could not read or write. Going to school was a dream (梦想) for many people.

Hanhan: Now almost everyone can go to primary and junior high schools. In some poor places, students can enjoy free meals after class. We have good chances to make our dreams come true.

Jianguo: I used to (过去) live in a hutong with my family. My brother and I shared a small room.

Hanhan: My family lives in a tall building. I have my own bedroom, but life in the hutong sounds (听起来) so interesting.

There are 520 boys and 500 girls in our school. The school made a survey（调查）about our favorite sports. Here are the results.

After seeing the results, the P. E. teacher advises us to join different sports clubs. He also encourages（鼓励）us to try some new sports. It may bring us some surprises.

A few years ago,I visited theclassical gardens of Suzhou. During the visit, my attention {#blank#}1{#/blank#}(draw) away from the plants, bridges and stones, towards {#blank#}2{#/blank#} walls of the gardens. Mostly white, some parts of the walls are losing small {#blank#}3{#/blank#}(piece) of their coverings.

 This creates space in which light and plants can be seen. The walls are not only the boundaries of the gardens, but they also form protected roads {#blank#}4{#/blank#} guide you on a trip.

 The memory of the white walls stayed with me. I kept imagining how many shadows(影) could be collected {#blank#}5{#/blank#} them to dance with the light. This fantastic moment was so {#blank#}6{#/blank#} (live) that I came back to explore with my camera.

{#blank#}7{#/blank#}(walk) freely with these walls and their marks, I began to feel like collecting all the stories that {#blank#}8{#/blank#}(be) painted there. Weather and time have turned these amazing white walls into Chinese landscape paintings.

I {#blank#}9{#/blank#}(take) the photos during the month of June, just after the rain. The air was full of small   drops of water, showing the light and the color of the things around. As color was born out of a dance between light and a body, when photographing in color I found {#blank#}10{#/blank#}(I) enjoying a moment of this dance.

Self﹣Management

By Li Ming

I am glad to share my ideas of self﹣management. 

Many people like to take a trip by plane，but I don't like it because an airport （机场） is usually far from the city. You have to get there early and wait for hours for the plane to take off （起飞） and it's often late. You can't open the windows. You can't choose the food. Planes are fast，but it still takes you hours to go out of the airport and into the city. 

I like traveling by train. I think trains are safe. The stations are usually in cities. When you are late for a train，you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time. 

I also like cars. You can start your trip when you want to，and you don't need to get to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.
