Question 10 is based on the passage you have just heard.

Passage One

听力原文

        Researchers have identified a potent new antibiotic compound using artificial intelligence. The antibiotic can kill very dangerous bacteria. According to a study published in the journal Cell, the compound successfully removed deadly strains of bacteria in mice which are resistant to all known antibiotics.

        (9) [The researchers say this is the first time that artificial intelligence has been used to find a powerful new antibiotic molecule.] Why does this matter? The answer is antibiotic resistance. This happens when bacteria develop the ability to survive the medications designed to kill them. (10) [Antibiotic resistance is a serious threat to health, and the problem is growing. This makes finding new antibiotics very important.] However, in recent decades, very few have been developed and those that have tend to be very similar to drugs already available. These searches also tend to only focus on a narrow spectrum of chemical compounds.

        But this is where artificial intelligence comes in. Why? To find new drugs, scientists screen molecules to predict how effective they might be. Typically, such screening is done by humans in the lab, which is both costly and slow. Artificial intelligence is different. It’s fast, and it can process a high volume. It can screen hundreds of millions of compounds to identify a few interesting candidates that require experimental testing.

        (11) [Artificial intelligence is also able to predict if compounds are likely to be toxic.] Some experts assert that this work signifies a paradigm shift in antibiotic discovery. It could change drug discovery more generally.

10. What makes it important to find new antibiotic drugs?（是什么让发现新型抗生素药物变得非常重要？）

解析：B。录音中提到，细菌会发展出对抗生素的耐药性，而这种耐药性是对健康的严重威胁，而且这个问题越来越严重。这（This）使得发现新型抗生素变得非常重要。其中的This指的就是前面提到的抗生素的耐药性，B项与此内容相符，是对录音中Antibiotic resistance的同义替换，因此正确。

错项排除：A项利用录音中的strains of bacteria进行干扰，但Ever-increasing在录音中无依据，故排除。录音中虽然提到最近的几十年里，很少有新的抗生素被开发出来，而这些药物通常与现有的药物非常相似（similar），但并没有说这是让发现新型抗生素药物变得重要的原因，故C项排除。D项利用录音中的growing和threat to health进行拼凑，但录音中是说抗生素的耐药性是对健康的严重威胁，而且这个问题越来越严重，并不是细菌对健康的威胁越来越大，故D项排除。
