Higgs boson一般指希格斯玻色子。希格斯玻色子(英语：Higgs boson)是粒子物理学标准模型预言的一种自旋为零的玻色子，不带电荷、色荷，极不稳定，生成后会立刻衰变。1964年，英国科学家彼得·希格斯提出了希格斯场的存在，并进而预言了希格斯玻色子的存在。

今年：法国科学家沙彭蒂耶(Emmanuelle Charpentier)和美国生物学家杜德纳(Jennifer A. Doudna) 因发现新型基因编辑技术获得本年度诺贝尔化学奖。据诺贝尔奖官网介绍，沙彭蒂耶和杜德纳发现了基因技术最厉害的工具：新型基因编辑技术CRISPR/Cas9基因剪刀。

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：

第一句：

What had begun as an ancient system of antiviral defense (主语从句)quicklybecame one of the most powerful and precise genome-editing tools available to science.

参考译文：最初的古老病毒防御系统迅速成为了科学界可用的最 强大、最精 确的基因组编辑工具之一。

第二句：

In less than a decade, Crispr has become commonplace in laboratories around the world.

参考译文：在不到十年的时间里，Crispr(短回文重复序列技术)成为了世界各地实验室中的常见技术。

第三句：

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

第四句：

Crispr’s rapid rise to near ubiquity, he added, (插入语)“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。”

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。
