问题    Overuse of antibiotics can lead to drug-resistant bacteria that have to be treated with more powerful and often more expensive drugs. And sometimes there are no drugs that work effectively, which increases the danger to people who are infected. The U. S. campaign for the smart use of antibiotics parallels similar efforts in Europe and Canada, which Hicks says underscores the international nature of the threat. " Resistant bacteria don’ t respect country or national boundaries and can easily travel on planes. Antibiotic resistance anywhere is really antibiotic resistance everywhere. "
选项
答案 过度使用抗生素会导致耐药菌，而这些细菌要得到治愈就必须使用药效更强大，通常也更昂贵的药物。有时甚至找不到有效的药物，这样会增加受感染人群的危险性。美国有关合理使用抗生素的活动产生了和欧洲及加拿大相似的效果，希克斯强调了这一威胁的国际性。“耐药菌不会受国家、国界的限制，它们能通过飞机进行肆意的传播。如果任何一个地方产生抗生素耐受性，那么整个世界到处都会有抗生素耐受性。”
