Question 11 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.

11. What does the passage say artificial intelligence is able to do in antibiotic research? （文章说人工智能可以在抗生素研究中做什么？）

解析：B。录音中提到，人工智能还能够预测化合物是否可能有毒（predict if compounds are likely to be toxic）。B项是对此内容的同义转述，故为正确答案。

错项排除：A项利用录音中的experimental testing进行干扰，但Dispense with在录音中无依据，故排除。C项的human reaction在录音中无依据，故排除。录音中虽然提到，细菌对抗生素的耐药性这一问题日益严重，但并没有说人工智能可与之对抗，D项的Combat主观臆断，故排除。
