选修7U23李仕才一、阅读理解A A new study has found the amount of antibiotics given to farm animals is expected to increase by two­thirds over the next 15 years. Researchers are linking the growing dependence on the drugs to rising demand for meat, milk and eggs. The researchers warn the drugs could quicken the development of antibiotics­resistant (耐抗生素的)infections. Such infections are already a major public health concern in the United States. Experts say when people stop living in poverty, 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. Increasing prosperity in Asia has meant people there are eating nearly four times as much meat, milk and dairy products as they did 50 years ago. To meet that demand, farms have put many animals into smaller spaces. As the animals are crowded together, often the easiest way to deal with some of the problems of crowding is to give them antibiotics. It’s clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually, and the antibiotics-resistant bacteria can spread to people. Doctors find that antibiotics that once worked against the infections no longer do. The bacteria have learned ways to fight the medicine. Doctors say the heavy use of antibiotics in animals is one of several reasons for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year. At least 23,000 die from an infection. Ramanan Laxminarayan heads the Center for Disease Dynamics, Economics and Policy. He says the problem is expected to get worse. He believes the use of antibiotics in animals will soon increase sharply. He says that will not be good for human health. He and other researchers wrote a report on the study, which was published in the Proceedings of theNational Academy of Sciences. They used data from the United Nations that tell how and where livestock(牲畜) are raised today. They then predicted how such production would change by 2030. Europe has banned the use of antibiotics to increase animal growth. And she adds the United States is hoping to persuade farmers to stop using antibiotics for that purpose.1.What is the passage mainly about?A.How to keep farm animals healthy.B.The abuse of antibiotics in human beings.C.A new way of raising farm animals.D.The disadvantages of using antibiotics.2.From he passage, we can infer that using antibiotics too often in farm animals ______.A.will lead to animals being less activeB.causes animals to get infected more easilyC.makes antibiotic-resistant bacteria spread to peopleD.has a negative effect on the growth of animals3.What accounts for the increasing amount of antibiotics given to farm animals?A.The increasing need for meat.B.The need for eating diversely.C.The less effective antibiotics.D.The limited farm technology.4.How will the use of antibiotics in animals according to Ramanan Laxminarayan?A.It will soon stop rising.B.It will soon increase sharply.C.It will soon rise steadily.D.It will soon increase slowly.参考答案： 1.D; 2.C; 3.A; 4.B解析： 1.[纵观全文便知,文章主要介绍了人们使用抗生素来饲养家畜带来的缺点。
