Unit 2 Healthy eating李仕才一、阅读理解AA new study has found the amount of antibiotics (抗生素) 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 the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibiotic­resistant infections (感染). Such infections are already a major public health concern in the United States.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. It's clear that antibiotics help animals stay healthy in crowded environments and grow faster. But bacteria can 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 antibiotic­resistant 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.【文章大意】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。

BIn 1959, when Jean Harper was in the third grade, her teacher gave the class an assignment to write a report on what they wanted to be when they grew up.Jean’s father was a crop dusting pilot in the little farming community in Northern California where she was raised, and Jean was very interested in airplanes and flying. She poured her heart into her report and included all of her dreams. She wanted to be a crop dusting pilot, make parachute jumps(跳伞), and be an airline pilot. Her paper came back with an "F" on it. The teacher told her it was a "fairy tale" and that none of the occupations she listed were women’s jobs. Jean was devastated and humiliated.One day in her senior year of high school, her English teacher Mrs Dorothy Slaton gave the class an assignment. "If you had unlimited money, unlimited access to the finest schools, and unlimited talents and abilities, what would you do?" Jean felt a rush of her old enthusiasm, and with excitement she wrote down all her old dreams. The teacher leaned forward over her desk and said, "You do have unlimited abilities and talents. When you leave school, if you don’t go for your dreams, no one will do it for you. You can have what you want if you want it enough."The hurt and fear of years of discouragement went away because of what Mrs Slaton had said. Jean felt excited and a little scared. She stayed after class and went up to the teacher’s desk. Jean thanked Mrs Slaton and told her about her dream of becoming a pilot. Mrs Slaton half rose and slapped the desk top. "Then do it!" she said.So Jean did. It didn’t happen overnight. It took her 10 years of hard work. It wasn’t in Jean’s nature to stand up for herself when someone refused or humiliated her. Instead, she would quietly try to find another way.She became a private pilot and then flew planes as a co-pilot (副驾驶员). In 1978, she became one of the first three female pilot trainees ever accepted by United Airlines and one of the only 50 women airline pilots in the nation at that time. Some years later, Jean Harper became a Boeing 737 captain for United Airlines.1.When Jean Harper was in the third grade, _________.A.it was common for women to be airline pilotsB. her father advised her to be a pilot like him in the futureC. she was unsure about what she wanted to be when she grew upD. she was deeply hurt by her teacher’s comment on her dreams2.What was Mrs Slaton’s reaction when she learned about Jean Harper’s dream?A.
