閱讀理解。

     Thomas Adams, an American inventor, is the father of modern bubble (泡泡) gum. During the 1870s,
Adams discovered a new way to make chewing gum by accident, while he was trying to find a use for chicle (糖膠樹(shù)膠)- Mr. Adams wanted to make rubber (橡膠) from chicle.
     Mr. Adams worked for a long time trying to make rubber from chicle. His oldest son also helped him
sometimes. But they never discovered a way to make it work. One day, Thomas Adams was in a store when
he heard a young girl ask for some chewing gum. Adams and his son had been chewing chicle while they
were working on the rubber, so he decided to give up trying to make rubber from the chicle and make gum
instead. At that time, chewing gum was made from spruces' sap (云杉樹(shù)液). This chewing gum didn't taste
very good. Adams thought chewing gum from chicle tasted better. He and his son wrapped small pieces of
chicle in colorful paper and sold it. People everywhere began chewing his gum at once.
     Mr. Adams' gum could make bubbles, but the bubbles were very sticky (膠粘的). Until 1928 Walter
Diemer found a way to improve chewing gum by making bubbles that were not sticky.
