It’s difficult to imagine a world without antibiotics. They cure diseases that killed our ancestors in crowds, and enable any number of medical procedures and treatments that we now take for granted. Yet in 1945, while accepting a Nobel Prize for【C1】________penicillin, Alexander Fleming【C2】________a future in which antibiotics had been used with【C3】________and bacteria had grown resistant to them. Today, this future is approaching. Speaking to reporters last fall, Tom Frieden, the director of the Centers for Disease Control and Prevention,【C4】________ a similar alarm: "If we’re not【C5】________, we will soon be in a post-antibiotic era. In fact, for some patients and some bacteria, we are already there."
The problem【C6】________overuse. Recent research by doctors at Harvard and Women’s Hospital found that the vast majority of antibiotics【C7】________for sore throats and acute bronchitis—an illness almost always caused by a【C8】________. not bacteria—arevuseless.
Up to 80 percent of all antibiotics used in the U.S. each year,【C9】________, are given to animals. Antibiotics are the lifeline of the meat and poultry industries, which have used drugs to domestic animals as a means of【C10】________growth and preventing illnesses caused by overcrowding and poor conditions.
An increasing number of bacterial【C11】________have taken the opportunity to evolve【C12】________the reach of antibiotics. The CDC’s 2013 threat report listed 17 antibiotic-resistant microorganisms that directly cause at least 23,000 deaths each year in the U.S.【C13】________. Globally, drug-resistant pneumonia is an ever-increasing threat. Reported cases have【C14】________over the past nine years, killing an estimated 170,000 people last year.
Although anti-bacterial resistance can be slowed, it is【C15】________. As a result, medicine companies have found antibiotics to be less【C16】________investments than drugs for chronic illnesses, which can be used over the long term.
If we don’t【C17】________our use of existing antibiotics and commit to developing new ones, the risks are not just medical, but【C18】________The CDC estimates that, in the United States, antibiotic resistance already costs $20 billion in【C19】________health-care spend and $35 billion in lost productivity【C20】________.
【C10】
选项
A、controlling
B、affecting
C、accelerating
D、compelling
答案
C
解析
空格和growth搭配,并与下文preventing illnesses一起说明把抗生素用于饲养家禽的用途。为了实现经济利益,肉禽业不仅需要保证禽畜的健康成长,也会考虑缩短动物生长的时间。C项accelerating意为“促进”。这里指美国的肉禽业使用抗生素加快畜禽的生长速度。A项controlling意为“控制”,抗生素也许能帮助畜禽生长,但不能随心地控制其生长。B项affecting意为“影响”,它看似符合语义要求,但不指明是什么样的影响,与空格前的a means of无法呼应。D项compelling意为“迫使(某人)做某事”,逻辑不对。
