Good morning! I’m Mary Brown. I’m in Class 6 in Yucai Middle School. Here are my three pictures.

In the first picture are my good friends. They are Linda and Jenny. We’re in the same school. Linda is in Class 5. She likes playing the guitar. Jenny and I are in the same class. We like swimming and running.

Who are they in the next picture? These are my uncle and aunt. My uncle is my mother’s brother. The boy and the girl are their children, Jack and Alice.

The last one is my family picture. This is my grandma. She is 80. She’s my mother’s mom. These are my parents. The girl is my sister Cathy. The boy is my brother Mike. Who is the baby? It’s my little sister, Ada. I’m not in the picture.

Do you know what you can do to protect the Earth? Here are some things you can do in your daily life. The more you do, the more you can help the Earth-our home.

Plant a tree

It’s good for the air and the land. It can shade your house and make you have a cool summer.

Turn off(关掉) computers at night

Turn off your computer if you don’t use it. If you don’t want to wait for your computer to start up, set it to turn on automatically(自动地) a few minutes before you get to work.

Buy some second-hand(二手的) things

Buy things from a second-hand store such as toys, bikes and other things. Second-hand stores often sell these things in good quality (质量) because they are used for such a short time.

Do you know anything about the Moon? How much do you know about it?

    31    ? Scientists tell us so much about the Moon. So it’s easy for us to have the idea of going to the Moon. But what would it be like to really go there?

The Moon is not a friendly place. There is no air or water. There are only lots of dust (灰尘) and mountains around on it.     32    . The temperature (温度) of the Moon is different from day to night.     33    . But it’s very cold at night.

    34     As we know, sound can only travel in the air but there is no air on the Moon.

But from the Moon, you can see our beautiful Earth. It is shining more brightly than the other stars in the dark.     35     The photos would be wonderful.

Hello, my name is Bill. I study in a middle school in the US. School     41     usually start at 9: 00 a. m. in the US. And I usually go to school at 8: 30 a. m. School is over at 3: 30 p. m. , so I have much time to     42     to different clubs（俱乐部）.

I’m     43     at all my subjects. But my favourite subject is cooking. All my teachers     44     very friendly. I never go home for lunch. I eat     45     at school. After that I often go to the school playground with     46     friend Mike. I like to play football there. But Mike     47     to run. Sometimes we just sit under the trees and     48     about our dreams. We also go to the Computer Centre to listen to     49     or send emails to our friends.

I like my school and have a good     50     at school every day.

I’m Lily. I study at a junior high school. We all know that the Earth is our home. It is very important for us. But people do something to pollute it. Many people burn things to make energy. They burn wood to keep warm. This pollutes the air. The air is very dirty now.

People make a lot of rubbish every day. They throw it away on the ground. This pollutes the land. Many plants die (死亡)because of the land pollution.

People also put the waste into the rivers and sea. This pollutes the water. The water becomes very dirty. Lots of fish die because of the water pollution.

I think we must ask people not to pollute the Earth. We must stop polluting the air, land and water. We must plant more trees and flowers. We live on the Earth. We must make the Earth clean and beautiful.
