Although the birds are not ___2______ immune, the scientists say their work shows it might be possible to 3 the virus in three years.</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(22, 126, 251);"> The latest results suggest that making ___4____ changes to the birds’ DNA could ____5____ fully immune ___6____. The researchers identified ___7______ genes they believed were important for the bird flu ( 8 known as avian influenza) virus to reproduce in the chickens. They made two small changes to one of the genes using a technique known as gene editing.</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(22, 126, 251);"> Bird flu is a major global threat, with a ___9______ impact in both farmed and wild bird populations. In the UK alone, the 10 outbreak of H5N1 bird flu has decimated seabird populations and cost the poultry industry more than £100 million in losses.</span></p><p class="ql-block"><br></p> <p class="ql-block" style="text-align: center;"><span style="font-size: 20px; color: rgb(57, 181, 74);">中文新闻：</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);"> 科学家用基因编辑让鸡获得对禽流感的部分抵抗力</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);"> 研究人员通过基因编辑让鸡获得了对禽流感的部分抵抗力。尽管经过基因编辑的鸡对禽流感不能完全免疫，但是科学家表示，他们的研究表明，未来三年内可能会成功阻断禽流感病毒。</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);"> 这一最新研究结果显示，进一步改变鸡的基因将能培育出对禽流感完全免疫的鸡。研究人员识别出了他们认为能帮助禽流感病毒在鸡体内复制的三种重要基因。他们用基因编辑术对其中一种基因做了两个小改动。</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);"> </span><b style="font-size: 20px; color: rgb(57, 181, 74);"><span class="ql-cursor"></span></b><span style="font-size: 20px; color: rgb(57, 181, 74);">禽流感是全球的一大健康威胁，对养殖和野生禽类具有毁灭性影响。仅在英国，当前暴发的H5N1禽流感就致使大批海鸟死亡，给养禽业造成超1亿英镑的损失。</span></p><p class="ql-block"><br></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">重点词汇</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">1. partially</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">英 [ˈpɑːʃəli] 美 [ˈpɑːrʃəli]</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">adv. 部分地</span></p><p class="ql-block"><br></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">2. avian</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">英 [ˈeɪviən] 美 [ˈeɪviən]</span></p><p class="ql-block"><span style="font-size: 20px; color: rgb(57, 181, 74);">adj. 鸟（类）的，关于鸟（类）的</span></p><p class="ql-block"><br></p><p class="ql-block"><br></p>
