28、emove the top from the can, but it was difficult to use. Finally, in 1870, William Lyman added a wheel to the can opener. The metal went around the top of the can and removed it easily.

29、d Luck Can Help!Clarence Birdseye had the chance to go on a trip to如e Arctic. When people there caught fish, they put the fish in a container (容器) of ice to freeze it quickly.

34、veral ways to support your favorite charity and enjoy yourselves at the same time.How about holding a bean bath competition? “How does this help?” you may ask yourselves.

35、ney! The longer you stay in the bath, the more money you collect for the charity your school has chosen! Its extremely messy, but its good fun! Just a piece of advice, though. Let your parents know what youre doing. Wear old clothes because theyre going to need washing after the competition!Heres an

36、other idea that we used at my school: organize a car wash. Everybody who has a car sooner or later washes it or has it washed. So why dont you and your classmates do the job?

37、e! At first, some of us were worried about getting wet or dirty and its true. But we also had fun, and at the end of the day it was really worth it!
