The World Health Organization(WHO)notes when people stop living in poverty(贫困)，the first thing they want to do is eat better，rather than earn more money.For most people，that means their diet should contain more meat.With the rapid development of Asia，people there are eating nearly four times as much meat，milk and other milk products as they did 50 years ago. To meet the need，farmers have put many animals into smaller spaces.As the animals are crowded together，the easiest way to deal with some of the problems of crowding is to give them antibiotics.Its clear that antibiotics help animals stay healthy in crowded environments and grow faster.But bacteria call develop resistance to the drugs gradually. Nowadays，doctors find antibiotics that once worked against the infections no longer work.The bacteria have learned ways to fight against the drugs.The heavy use of antibiotics in farm animals is responsible for the growth of antibiotic resistance worldwide.Each year in the United States，at least two million people get antibiotic-resistant infections and at least 23，000 die from these infections. Europe has banned the use of antibiotics to increase animal growth.And the United States is hoping to persuade farmers to stop using antibiotics for that purpose. 【语篇解读】　本文主要围绕在农场动物身上使用抗生素的负面影响展开。 【长难句分析】　The World Health Organization(WHO) notes when people stop living in poverty(贫困)，the first thing they want to do is eat better，rather than earn more money. 分析：本句为复合句。notes后接省略了连接词that的宾语从句；该宾语从句中含
