Why Are Pig Farmers Still Using Growth­Promoting Drugs?
It's one of the most controversial practices in agriculture: feeding small amounts of antibiotics to animals in order to make them grow faster. But what if the drugs don't even work very well? There's some good evidence that they don't, 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 accomplish the same thing through improved hygiene(卫生). As a result, the drugs have become largely superfluous—yet 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. There's not a piglet in sight. “This room just got completely washed and disinfected, and now it's going to sit here and dry for a while，” he says.
A whole group of pigs will come 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 disease—and pigs actually grew faster.
1．One of the advantages of using antibiotics in the past is that it ________.
A．helped animals grow faster
B．decreased the death rate of animals
C．helped animals have a better appetite
D．increased animal reproduction
2．Pigs were more easily infected in the past because ________.
A．they used antibiotics
B．they were always close together
C．they were raised on the playground
D．they moved from one farm to another
3．The underlined word “superfluous” most probably means ________.
A．abused　　　　　　　 B．necessary
C．available D．addictive
4．The author seems ________ on the issue of dropping antibiotics on pigs.
A．optimistic B．worried
C．doubtful D．indifferent
答案与解析
本文就现在农夫照旧给猪使用抗生素一事发表科学的看法和依据。
1．A　细节理解题。依据第一段提到It's one of the most controversial practices in agriculture: feeding small amounts of antibiotics to animals in order to make them grow faster.农业上有个有争议的方法，给猪喂抗生素来让它长得更快，故选A项
2．B　推理推断题。依据第三段提到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...这些猪被养在一个栏或几个栏里，这意味着很简洁传染，故选B项。
3．A　词义猜想题。依据第一段提到In recent years, however, pork producers found other ways to accomplish the same thing through improved hygiene(卫生). As a result, the drugs have become largely superfluous—yet many farmers still use them. 最终这些年，养猪的人通过卫生可以达到同样的效果，结果药物就被滥用，然而一些农夫照旧再用，故选A项。
4．A　推理推断题。依据最终一段提到When farmers adopted multisite production, it cut down on disease—and pigs actually grew faster.当农夫接受多站点的生产方式，这会削减疾病，长得的确是更快，故作者的观点是格外乐观的，所以选A项。
Ⅱ.阅读填句
(2021·吉林市质检)
__1__ We are learning from life constantly, as long as we recognize and accept those lessons. When you choose to be a student of life, you open yourself to limitless opportunities.
Explore the world. Don't limit yourself to your hometown or to the city you got your first job. __2__ It doesn't have to be just one town or one apartment complex. Backpacking may not be for everyone, but it's the only way you can see the world. Travelling doesn't just have to be going overseas but also dropping by many states. Culture exists not just in a country but even in small communities.
Acquire new life skills. Maybe it's time that you finally learn how to fix a broken faucet or even fix the faulty light in your bathroom. You can finally cross out your bucket list items that have been there forever. Learn how to drive a car or ride a bike. There are definitely things you don't know how to do, and you have a lifetime ahead of you to learn. __3__
Be cultured. Watch as many movies and read as many books as possible. And it doesn't mean that you only watch the ones with high ratings from critics. Books and movies are the fruit of the writers' or the makers' life experiences and understanding of their surroundings. Movies and books are a good look into how people interpret the world.
__4__ For some individuals, to grow older means to keep your circle of friends down to a few, but that shouldn't stop you from meeting new people. Widen your circle by allowing people into your life and letting them get to know you. Widening your circle to people from all walks of life gives you a bigger and better perspective of the world.
Do many first's. When was the last time you did something for the first time? __5__. It can be as simple as watching a movie alone or as big as trying bungee jumping. Doing something for the first time doesn't need to have a life­changing effect. It can be a simple realization that apparently, going to a film screening by yourself isn't so bad.
So, there are so much more to learn, especially now that we're virtually connected to everyone in the world. As a student of life, it's really up to you to use all your resources and make it into something enriching.
A．Widen your circle.
B．Entertain yourself.
C．Lessons are not limited to our academic studies.
D．It's never too late to start learning something new.
E．You don't always need a deep understanding for everything you do.
F．Go beyond the place you consider home, because home can be many places.
G．If you can't think of the answer, maybe you need to go out and try something new.
答案与解析
