當(dāng)提及六級(jí)聽(tīng)力時(shí)，尤其是英語(yǔ)六級(jí)真題聽(tīng)力，我們不禁會(huì)想起那些考驗(yàn)英語(yǔ)學(xué)習(xí)者聽(tīng)力理解能力的挑戰(zhàn)。作為英語(yǔ)六級(jí)考試的重要組成部分，六級(jí)聽(tīng)力部分不僅要求考生能夠捕捉和識(shí)別出基本的語(yǔ)言信息，更需要他們?cè)谟邢薜臅r(shí)間內(nèi)對(duì)復(fù)雜的語(yǔ)境進(jìn)行準(zhǔn)確理解，并快速作出反應(yīng)。小編為大家整理了2022年6月英語(yǔ)六級(jí)真題聽(tīng)力第一套Passage 1的內(nèi)容，希望能對(duì)您有所幫助！
英文原文
Passage 1
短文1
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.
研究人員使用人工智能發(fā)現(xiàn)了一種強(qiáng)大的新型抗生素化合物。據(jù)《細(xì)胞》雜志發(fā)表的一項(xiàng)研究，這種抗生素可以殺死非常危險(xiǎn)的細(xì)菌。該化合物成功清除了小鼠體內(nèi)對(duì)所有已知抗生素具有耐藥性的致命細(xì)菌株。
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 developed the ability to survive the medications designed to kill them.
研究人員表示，這是首次使用人工智能來(lái)發(fā)現(xiàn)一種強(qiáng)大的新型抗生素分子。為什么這很重要？答案是抗生素耐藥性。當(dāng)細(xì)菌發(fā)展出存活于旨在殺死它們的藥物的能力時(shí)，就會(huì)發(fā)生這種情況。
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.
抗生素耐藥性是健康的一個(gè)嚴(yán)重威脅，而且這個(gè)問(wèn)題正在加劇。這使得發(fā)現(xiàn)新的抗生素變得非常重要。然而，近幾十年來(lái)，只有很少的新型抗生素被開(kāi)發(fā)出來(lái)，而且它們往往與已經(jīng)上市的藥物非常相似。這些搜索也往往只關(guān)注一小部分化學(xué)化合物。
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.
但這就是人工智能發(fā)揮作用的地方。為什么呢？為了發(fā)現(xiàn)新藥，科學(xué)家們篩選分子以預(yù)測(cè)它們可能有多有效。通常，這種篩選是由實(shí)驗(yàn)室里的人類進(jìn)行的，既昂貴又緩慢。人工智能則不同。它速度快，處理量大。它可以篩選數(shù)億種化合物，以確定少數(shù)幾個(gè)需要實(shí)驗(yàn)測(cè)試的有趣候選物。
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.
人工智能還能夠預(yù)測(cè)化合物是否可能有毒。一些專家斷言，這項(xiàng)工作標(biāo)志著抗生素發(fā)現(xiàn)領(lǐng)域的范式轉(zhuǎn)變。它可能會(huì)更廣泛地改變藥物發(fā)現(xiàn)。
