Scientists have developed a non-stick chewing gum(口香糖). The new gum can     【小题1】    (remove) easily from pavements, shoes and clothes. It’s the result of polymer (聚合体) research at the University of Bristol and could be launched mercially in 2008.     【小题2】  it catches on(流行), the product will solve    【小题3】    major headache for present authorities around the world.
“A great    【小题4】    (disadvantage) of our Clean Gum is that it is easy to remove and has the potential to be    【小题5】    (environment) degradable (可降解的),” said Terence Cosgrove, a professor of chemistry    【小题6】    helped to found a pany called Revolymer to mercialize the technology.
Today’s chewing gums are made     【小题7】synthetic latex(人工制造的乳液), which is resistant to the weather and is strongly sticky. The new gum adds a special polymer to change its properties(特性),     【小题8】    (make) it far less sticky.
In two street trials,    【小题9】    mercial gums remained stuck to the pavement     【小题10】      Clean Gum came away naturally in all cases. be removed
