Write a passage to describe the picture. Use your answers to the questions in Activity 5 to help you.
We have just received a message from our spaceship to Mars. Our spaceship has discovered aliens there. They have never sent us a message because they don’t know how to communicate with us. They have not visited the earth because they don’t know how to fly to our planet, and they prefer life on Mars. They seem very happy on their planet. They have used parts from the other spaceships from the earth to make TVs, radios, etc. We hope they don’t do the same with this one.
