  今天的句子:

  What had begun as an ancient system of antiviral defense quickly became one of the most powerful and precise genome-editing tools available to science. In less than a decade, Crispr has become commonplace in laboratories around the world.“Other technologies sometimes take a couple of decades before they come into regular practice,” Dr. Collins said. Crispr’s rapid rise to near ubiquity, he added, “is remarkable.”

  思考题:

  Dr. Collins holds Crispr as remarkable because__.

  A. it is the first genome-editing tools available

  B. it has been applied to antiviral defense system

  C. it has been invented by two female scientists

  D. it has been widely adopted at an unusual pace

  词汇突破:

  antiviral:抗病毒

  precise: 精确的

  ubiquity 似乎无所不在的,十分普遍的

  remarkable 令人惊讶的

  句子解析:

  思考题解析:

  A. it is the first genome-editing tools available

  (它是第一个可用的基因编辑工具)

  不是第一个,是最广泛运用的。

  而且和题干不搭!

  A选项错误。

  B. it has been applied to antiviral defense system

  (它被用于病毒防御系统)

  B选项错误。

  C. it has been invented by two female scientists

  (它由两位女性科学家发明)

  这是有用无关的信息干扰!

  C选项错误。

  D. it has been widely adopted at an unusual pace

  (它被以非同寻常的速度广泛地应用)

  对应最后两句!

  Other technologies sometimes take a couple of decades before they come into regular practice,” Dr. Collins said.

  Crispr’s rapid rise to near ubiquity, he added, “is remarkable.”

  参考译文:“其他技术有时要过几十年才能被常规应用。” 柯林博士说。他补充道,Crispr迅速崛起成为通用技术,“非常了不得。”D选项正确。

  Nobel Prize in Chemistry Awarded to 2 Scientists for Work on Genome Editing

  两名科学家因基因编辑获得诺贝尔化学奖

  来源:https://www.nytimes.com/2020/10/07/science/nobel-prize-chemistry-crispr.html

  背景:近日,法国科学家埃玛纽埃尔·沙尔庞捷和美国科学家珍妮弗·杜德纳因为“研发了一种基因编辑方法”,重写“生命密码”,获得了2020年诺贝尔化学奖。她们俩是诺贝尔化学奖第6位和第7位女性诺贝尔化学奖得主,也是第一次由两位女性共同获得诺奖。同时,让她们青史留名的CRISPR/Cas9基因编辑方法也备受争议。它是一种生物学工具,利用了原核生物古老的防病毒机制,可以前所未有的精度编辑基因组,而且比其他任何方法都要简便、便宜。前些年,万夫所指的贺建奎“基因编辑婴儿”事件使用的就是CRISPR/Cas9技术。这项技术在生物学和医学领域无疑将带来革命性的影响,也将在开拓可能性的同时不可避免地引发激烈的伦理争议。
