　　So, do you think that making our world a cleaner and better place is hard? Well, to tell you the truth, it is very easy! You can help make our world cleaner and more beautiful by picking up at least1 20 pieces of litter2 from the ground every day.

　　If everyone does this, we can keep our world clean and keep garbage off3 our city streets. Now, you just need to find the courage to tell people“Do not throw garbage just anywhere! Put litter in the garbage can4!”

　　—Joyce
