For years, many of us have relied on antibiotic use to treat various infections and the reality is that antibiotics have been responsible for saving millions of lives since penicillin, one of the earliest antibiotics, was first used on a clinical basis 70 years ago. However, today is a new era in which taking antibiotics can cause some very dangerous and potentially life-threatening situations. In fact, you may have heard about the new "superbugs", [13]which are antibiotic-resistant bacteria that have developed as a result of overprescribed antibiotics. In the past, health experts warned us that the day would come in which it would become very difficult to provide medical care for even common problems such as lung infection or severe sore throat. And, apparently, [14]that day has come because seemingly routine operations such as knee replacements are now much more hazardous due to the looming threat of these infections.
    The problem has grown into such epidemic proportions that this severe strain of resistant bacteria is being blamed for nearly 700,000 deaths each year throughout the world; and, unfortunately, health experts worry that the number will rise to 10 million or more on a yearly basis by 2050. With such a large life-threatening epidemic, [15]it is sad to say that only 1.2% of budgetary money for the National Institutes of Health is currently being spent on research to tackle this problem, this is a far cry from the funds necessary for a problem of such magnitude.
13. What do we learn about the "superbugs"?
14. What is the result of the overuse of antibiotics?
15. What is most urgently needed for tackling the large life-threatening epidemic according to the speaker?

选项 A、They are life-threatening diseases.
B、They are overprescribed antibiotics.
C、They are new species of big insects.
D、They are antibiotic-resistant bacteria.

答案 D

解析 录音开头明确指出“超级细菌”(superbugs)的定义:这是一种耐抗生素的细菌(antibiotic-resistant bacteria),是由于对抗生素的过度用药而产生的。D项“它们是耐抗生素的细菌”为录音的原词复现,为正确答案。
