I can’t remember when I started collecting litter. But it was when I got tired of 46 litter nearby that I realized no one else was going to pick it up. I live near a forest in Ohio, America. I can walk there 47 three minutes. I used to love going there to play with my dog. But one day there was 48 much litter there that I became very unhappy. I decided to clean up the forest, and I wanted to 49 happy when I went again. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes 50 I started to pick up litter, my bag was full! There were cans, bottles, broken glass and newspapers in it. From then on, I 51 to the forest four times a year to pick up litter. I often stay there for three hours. It makes me feel 52 to do something for the environment. After each trip, I look through all the litter that I’ve collected. If 53 of it is recyclable（可回收利用的）, I’ll keep it. I can’t understand why people drop litter. But I will keep on picking it up 54 they stop dropping it.. I know I am only doing a small bit 55 the earth, but I still think it is important. 小题1:A.seeing           B.throwing          C.dropping 小题2:A.after            B.for               C.in 小题3:A.such         B.very              C.so 小题4:A.make         B.feel              C.look 小题5:A.after            B.later             C.before 小题6:A.had gone     B.have gone         C.go 小题7:A.tired            B.sad               C.great 小题8:A.many         B.few               C.any 小题9:A.until            B.after             C.as soon as 小题10:A.helped          B.to help               C.help
