“Green” is more than just a color. It means that you should live to protect the environment—the water, the land and the air. You can be a green kid by following these steps：
Reduce it!
When you use less of something, you do a good thing for the earth. For example, a shorter shower means you use less water. Turn off the water when you are brushing your teeth.
Reuse it!
Many times, even if you don't need something, someone else might just need it. For example, if your younger sister doesn't play with her bear toy, you can give it to your neighbor. Try to change books, toys, even clothes with friends.
Enjoy it!
It's true that pollution is a great problem now, ________ the earth is still a beautiful and interesting place to explore(探索). Go for a hike(远足)，visit nature centers and gardens, climb mountains and take a boat in the rivers… Outdoor activities are good for you.

Ⅶ.One possible version：
Last Monday our class held an activity about saving and protecting water.
Mr. Wang was invited to give us a talk. After his speech, we had a discussion about how to save and protect water.
Now we know that some of the rivers are polluted in our country and that we are short of water although there are some rivers and lakes in our city. As a result, we need to save and protect water. For example, we shouldn't leave water running after using it. Besides, we mustn't throw rubbish into the rivers.
After taking part in the activity, we had a better understanding of the importance of saving water and protecting the environment.
