Sample article ： After visiting the moon, I was lucky enough to make a trip to Mars. Before I left, I surfed the Internet and found the gravity on Mars was much smaller than that of the earth. In order not to float away, I had to wear special spacesuit . What’s more, I must take special food to eat and enough oxygen to breathe. The moment I landed on Mars, I cheered up immediately and couldn’t wait to explore it. However, I found it was very cold, super windy, and extremely dry, just like a desert. In fact, there is no water and life there. After returning to the earth, I felt lucky to live on the earth , where there is pleasant climate, sweet water and many other beautiful

things. How beautiful our earth is! We must protect our homeland-the earth and everything around us.
