But what if the drugs dont even work very well? Theres some good evidence that they dont, at least in pigs. They used to deliver a boost in growth, but that effect has disappeared in recent years or declined greatly. The reason for this is interesting and even paradoxical. Researchers think the antibiotics used to work by suppressing lowgrade infections. In recent years, however, pork producers found other ways to acplish the same thing through improved hygiene(衛(wèi)生). As a result, the drugs have bee largely superfluousyet many farmers still use them.To understand how this happened, you have to step back in time, says Steve Dritz, a specialist in pig nutrition at Kansas State University. Sixty years ago, when antibiotics were new, “people started treating animals, and feeding the antibiotics, and finding that they had increased growth rates and feed efficiencies，” he says. Nurseryage pigs, for instance, grew 12 to 15 percent faster with antibiotics. The animals also needed less feed to reach full weight. Other studies showed similar results in chickens and cattle. In the 1980s, a new set of studies found similar effects. So the growthpromoting effects of antibiotics became standard practice among meat producers. Fast forward to the 1990s. Dritz was starting his career as a scientist at Kansas State University, and pork production was changing dramatically.Previously, pigs were born and raised in one barn or in several barns close together. This meant infections could easily pass from one generation to the next, the way that kids share germs between their friends on the playground and their parents at home. Under the new system, when piglets are weaned, they move to a whole different place. That new site is carefully scrubbed and free of disease.Craig Rowles, who runs a large swine operation in Carroll, Lowa, shows me one such room. Theres not a piglet in sight. “This room just got pletely washed and disinfected, and now its going to sit here and dry for a while，” he says.A whole group of pigs will e in here together, and later they will move out together to yet another site. “That group of pigs will stay together until they go to market，” Rowles says.The groups are kept strictly separated from each other. If workers move between the groups, they first have to change their boots.When farmers adopted multisite production, it cut down on diseaseand pigs actually grew faster.1One of the advantages of using antibiotics in the past is that it _.Ahelped animals grow fasterBdecreased the death rate of animalsChelped animals have a better appetiteDincreased animal reproduction2Pigs were more easily infected in the past because _.Athey used antibioticsBthey were always close togetherCthey were raised on the playgroundDthey moved from one farm to another3The underlined word “superfluous” most probably means _.AabusedBnecessaryCavailable Daddictive4The author seems _ on the issue of dropping antibiotics on pigs.Aoptimistic BworriedCdoubtful Dindifferent答案與解析本文就現(xiàn)在農(nóng)民仍然給豬使用抗生素一事發(fā)表科學(xué)的看法和依據(jù)。1A細(xì)節(jié)理解題。根據(jù)第一段提到Its one of the most controversial practices in agriculture: feeding small amounts of antibiotics to animals in order to make them grow faster.農(nóng)業(yè)上有個(gè)有爭議的方法，給豬喂抗生素來讓它長得更快，故選A項(xiàng)。2B推理判斷題。根據(jù)第三段提到Previously, pigs were born and raised in one barn or in several barns close together. This meant infections could easily pass from one generation to the next.這些豬被養(yǎng)在一個(gè)欄或幾個(gè)欄里，這意味著很容易傳染，故選B項(xiàng)。3A詞義猜測題。根據(jù)第一段提到In recent years, however, pork producers found other ways to acplish the same thing through improved hygiene(衛(wèi)生). As a result, the drugs have bee largely superfluousyet many farmers still use them. 最后這些年，養(yǎng)豬的人通過衛(wèi)生可以達(dá)到同樣的效果，結(jié)果藥物就被濫用，然而一些農(nóng)民仍然再用，故選A項(xiàng)。4A推理判斷題。根據(jù)最后一段提到When farmers adopted multisite production, it cut down on diseaseand pigs actually grew faster.當(dāng)農(nóng)民采用多站點(diǎn)的生產(chǎn)方式，這會(huì)減少疾病，長得確實(shí)是更快，故作者的觀點(diǎn)是非常樂觀的，所以選A項(xiàng)。.閱讀填句(xx吉林市質(zhì)檢)_1_ We are learning from life constantly, as long as we recognize and accept those lessons.
