Now that the earth’s gravity is six times as strong as the moon’s, life on the moon is quite different. If I visit the moon, I may meet with some problems. For example, I may fly off the moon and into space, which is very dangerous. In addition, how to protect the environment on the moon remains a problem.

My article (part 1):

Therefore, on the moon, I must walk slowly and mustn’t jump. Besides, I ought to watch out for my balance all the time. Not only should I learn to protect myself, but also I should pay attention to protecting the environment. I will collect the rubbish and the daily waste, and then bring them back to the earth. Also, I can persuade others to protect the environment from being polluted.

My article (part 2):

Step VI Self-assessment( 自我评价 )1 Have you understood the change in the gravity and the weight during the trip?
