问题补充：
I can’t remember when I started collecting litter. But it was when I got tired of seeing litter nearby and 1 that no one else was going to pick it up.
I live near a forest in Ohio, America. I can walk there 2 three minutes. I used to love going there to play with my dog. But one day there was 3 much litter there that I became very unhappy. I decided I had to clean up the forest. I wanted to feel happy 4 there again.
I 5 my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting to pick up litter, my bag was 6! It had cans, bottles, broken glasses and newspapers in it. From then on, I went to the forest four times a year to pick up litter. I’m often there for three hours. It makes me feel 7 to do something for the environment.
After each trip, I look at all the litter that I’ve found. If 8 of it is recyclable(可回收的) , I keep it. I can’t understand 9 people drop litter. But I will keep picking it up until they stop dropping it. I know I am only doing a small bit to 10 the earth, but I still think it is important.
