【正确答案】 C

【答案解析】[听力原文] The World Health Organization says an increasing number of infections cannot be treated because of growing resistance to antibiotic drugs. This resistance puts the lives of millions of people at risk. The WHO studied 133 countries. It found that no part of the world is ready to fight the growing threat. It says only twenty-five percent of the countries it studied has a thorough plan to fight resistance to antibiotics and other similar medicines. The study also found that many people do not know about the problem. And, the researchers say many people believe antibiotics are effective against viral infections. The organization says this misunderstanding causes antibiotics to be used even when they will not work. The resulting overuse can cause resistance. 'Researchers discovered that antibiotics and similar medicines are sold in many places without a doctor's prescription. This increases the possibility of overuse of antibiotics and increases resistance.' said Charles Penn, a WHO expert on antibiotic resistance. The WHO official says urgent action is needed or the world will enter a 'post-antibiotic' period. That means a time when common infections and minor injuries could once again kill people. 'Doctors also would lose the ability to treat many more serious conditions like tuberculosis, infectious wasting disease especially connected with lungs. And advanced medical treatments like major surgery will become much riskier or impossible,' Charles Penn said. This is not a problem for future worry. This is a problem for today. Charles Penn says there are diseases and infections that no longer are treatable with available antibiotics today. For example, he says antibiotics no longer affect the disease AIDS. 'Another example would be hundreds of thousands of new cases of multi-drug-resistant tuberculosis each year. Again, these are infections that have already become very difficult to treat. And it's difficult to put a precise number on what will happen in the future, but if we do not act it can only get worse.' The World Health Assembly is now meeting in Geneva to discuss a Global Action Plan to fight antibiotic resistance and other similar resistance. How many percent of the countries studied by WHO are ready to fight resistance to antibiotics? 题目问在世界卫生组织调查研究的国家中，有多少国家已经准备好应对抗生素耐药性的问题。录音提到，世卫组织说有25%的国家对此已有一个很好的应对计划，故C正确。 录音中虽然提到了133这个数字，但这是指该研究共涉及到的国家数量，并非题目所问内容，13%、33%、35%均为近音干扰，故A、B、D排除。

【正确答案】 B

【答案解析】[听力原文] According to the WHO, why have the antibiotics been overused? 选项都以Because开头，可知本题问原因；从选项内容看，问题可能与某种药物有关。题目问世卫组织，抗生素为何会被滥用。录音明确提到，抗生素被误以为对抗病毒性感染是有效的，这导致了抗生素的滥用，故选B“抗生素的疗效被夸大”。 A“抗生素对大部分疾病都有效”缺乏录音依据。录音提到，在很多地方，抗生素常常在没有医生处方的情况下出售，但这并不等同于医生故意开出夸大的药方，故排除C。录音中未提到抗生素的价格，故D也可排除。

【正确答案】 A

【答案解析】[听力原文] According to the WHO, what is the 'post-antibiotic' period? 选项都有关键词time，涉及疾病和药物等，问题可能问与疾病、药物有关的一个时间段。题目问根据世卫组织，后抗生素时期指的是什么。录音明确指出，在后抗生素时期，即使很普通的干扰或轻伤也可能致死，A“普通的感染也能致命”与录音所述的后抗生素时期的特征相符，故为答案。 B“没有一个国家为应战抗生素做好准备”表述不正确，我们应战的是对抗生素的耐药性问题而非抗生素本身，而且录音也提到25%的国家有应战的计划，故B错误。录音没有提到新抗生素的发明，故排除C。D“大部分重病都能被治愈”正好与后抗生素时代的特征相反，故排除。
