2021何凯文每日一句第113句

今天的句子:

In a field where scientists have spent decades focused on genetics and the buildup of damaged protein fragments called beta-amyloid as causes of the disease, now many experts agree that air pollution plays a major role. For the most common form of Alzheimer’s, known as late-onset disease, researchers now estimate that at least 40 and as much as 65 percent of the risk involves nongenetic influences such as lifestyle and harmful environmental exposure.

思考题:

Traditional views on Alzheimer’s agreed that___.

A.it could be mainly attributed to genetics

B.it had a close relation to lifestyle choices

C.it was triggered by nongenetic factors

D.it was related to the harmful air pollution

词汇突破:

buildup沉积

protein fragments蛋白质片段

beta-amyloid β-淀粉样蛋白

Alzheimer’s 阿尔茨海默氏症

late-onset disease 晚发性亚型

亚型=类型=form

nongenetic 非基因的

involve 涉及到

句子解析:

第一句:

In a field where scientists have spent decades focused on genetics and the buildup of damaged protein fragments called beta-amyloid as causes of the disease(传统的观点), now many experts agree that air pollution plays a major role.

参考译文:在这一领域,科学家数十年来一直专注于遗传学,并将被称为β-淀粉样蛋白的受损蛋白质片段的沉积视作疾病成因,现在许多专家都同意空气污染起着重要作用。

注意:这里的疾病disease就包括后文的Alzheimer’s这就是阅读的相关性原则。

第二句:

For the most common form of Alzheimer’s, known as late-onset disease,researchers now(现在的观点) estimate that at least 40 and as much as 65 percent of the risk involves nongenetic influences such as lifestyle and harmful environmental exposure.

参考译文:研究人员现在估计,对于最常见的阿尔茨海默氏症亚型,即晚发性亚型,风险因素中至少40%到65%涉及非遗传影响,如生活方式和有害的环境暴露。

思考题解析:

Traditional views on Alzheimer’s agreed that___.

题干暗藏杀机!

问的是传统观点!

不是问现在的观点!

所以BCD都属于定位错误!

A正确!一剑封喉!你就说服不服吧!

A. it could be mainly attributed to genetics

(它可能主要归因于基因)

A选项正确。

B. it had a close relation to lifestyle choices

(它与生活方式的选择密切相关)

B选项错误。

C. it was triggered by nongenetic factors

它是由非基因因素引起的。

D. it was proven to be related to pollution

(它被证明与污染有关)

D选项错误。
