Rushing Science in the Pandemic

疫情之下的科学快跑

背景：科研通常是一个沉闷又冗长的过程：科学家检查数据，复核数据，审读结论，复审结论，然后再把自己艰苦的工作成果发给科学期刊，期刊编辑在出版成果之前会再对论文进行同行评审等进一步的审核。但当下的新冠疫情却并不会恪守如此谨慎的时间轴，面对新的传染性疾病，公共卫生专家、政府官员、医生和病人们都急于从科学出版物中找到答案。在这种快速出版的压力下，往常的科研和出版全流程无法被严格地执行，各大顶 级医学期刊最近都出现了可靠性极为可疑的文章和的快速撤稿。对于广大医务工作者来说，这些错误的科研导向平添了他们本就不小的压力。一方面，疫情要求我们在科技出版领域缩短周期，另一方面，不可靠的成果有百害无一利。面对这个僵局，整个科研和科技出版应对流程进行改革，加大数据公开和关键信息的透明度，聚众人之力，让重要可靠的成果能快速地被阅读和核实。

句子解析和题目解析：

For doctors treating patients with COVID-19, the pressures of managing a pandemic illness are aggravated by the fact that (同位语从句)：their North Stars for treatment decisions—peer-reviewed reports in medical journals—are also facing steep challenges in finding ways to publish reliable information / with far less time than they are accustomed to having.

首先句子主干：

the pressures are aggravated

(医生的压力加剧了)

原因就是by后面的内容，

这就是结构决定的，传说中的：读不懂也需要知道后面是原因。

原因是一个事实(fact)什么事实?后面加上了一个从句：

这里的：their North Star =peer-reviewed reports in medical journals

所以原因就是：

their North Stars are also facing steep challenges

=peer-reviewed reports are under challenges

所以答案就是：

C. peer-reviewed reports are under challenges

同行评估的报告受到了挑战

正确答案就是这样出来的!

再看其他的三个选项：

A.medical journals have no stable data source

医学期刊没有稳定的数据来源。

没有提及，错!

B.peer-review process has been overstated

同行评估的过程被高估了。

没有提及，错!

C. peer-reviewed reports are under challenges

同行评估的报告受到了挑战

D. treatment decisions are facing challenges

治疗的决定受到了挑战

这里就是传说中的：“拼凑”也就是“拼多多”，

看好哦：

their North Star for treatment decisions are also facing steep challenges.

不等于:

treatment decisions are also facing steep challenges.

(虽然在阅读中我们要小心“答案的拼多多”!)
