- A. With researchers being aware of public interests.
- B. With its findings published in prominent journals.
- C. With researchers creating products that enhance social development.
- D. With its findings properly communicated beyond the academic circle.
答案：D
答案句：For research to serve its full purpose, the results must leave the confines of research laboratories and academic journals. … Findings effectively communicated can go a long way to serve the interests of the public.
参考译文：为了使研究发挥其全部作用，研究结果必须走出研究实验室和学术期刊的局限。… 有效传达的研究发现可以大大有助于服务公众利益。
定位线索：题干“How can research serve its full purpose”→答案句“For research to serve its full purpose, the results must leave the confines of research laboratories and academic journals”；文中“leave the confines of research laboratories and academic journals”对应选项D“properly communicated beyond the academic circle”。
解析：题干问研究如何发挥全部作用，答案句明确指出研究结果必须离开实验室和学术期刊的局限，即需要传播到学术圈之外。正确选项D“properly communicated beyond the academic circle”是对此的同义转述。选项A“researchers being aware of public interests”无中生有，文中未提及研究者需意识到公众利益；选项B“published in prominent journals”与原文相反，原文强调要离开学术期刊；选项C“creating products that enhance social development”是研究本身的目的，而非发挥全部作用的方式。
47. Why do ordinary readers find it difficult to access the results of researchers' studies?
- A. They cannot understand the academic language used for reporting these results.
- B. They feel intimidated by the jargon researchers use to describe their findings.
- C. They do not attend conferences where these results are freely available.
- D. They have few chances to locate the journals that publish these findings.
答案：A
答案句：But few journals allow everybody to read the findings. Even articles freely available are usually written in academic language incomprehensible to the average reader.
参考译文：但很少有期刊允许所有人阅读研究结果。即使是免费获取的文章，也通常用普通读者无法理解的学术语言写成。
定位线索：题干“Why do ordinary readers find it difficult to access the results”→答案句“Even articles freely available are usually written in academic language incomprehensible to the average reader”；文中“incomprehensible to the average reader”对应选项A“cannot understand the academic language”。
解析：题干问普通读者为何难以获取研究结果，答案句明确指出即使免费文章也使用普通读者无法理解的学术语言。正确选项A“cannot understand the academic language used for reporting these results”是对此的直接对应。选项B“feel intimidated”无中生有，文中未提及恐惧感；选项C“do not attend conferences”答非所问，文中未提及会议获取问题；选项D“have few chances to locate the journals”无中生有，文中未提及查找困难。

参考译文：由于技术术语，研究者呈现的研究结果可能会被误解。但这可以通过研究者聘请专业作家或传播官员来帮助将他们的研究转化为更容易理解的语言，并与媒体和公众广泛分享来解决。
定位线索：题干“Why are researchers advised to engage the services of professional writers or communication officers”→答案句“to help with translating their study into more accessible language”；文中“misunderstanding of the findings”和“more accessible language”对应选项C“make their publications correctly understood by the public”。
解析：题干问为何建议研究者聘请专业作家或传播官员，答案句明确指出是为了解决因技术术语导致的误解，将研究转化为更容易理解的语言。正确选项C“make their publications correctly understood by the public”是对此的同义转述。选项A“satisfy ethics committees' mandatory requirements”偷换概念，文中提及伦理委员会要求分享结果，但未说聘请专业作家是为了满足该要求；选项B“translate into languages accessible to readers overseas”范围缩小，文中说的是“more accessible language”，指更易理解的语言而非外语；选项D“render their findings acceptable by prominent journals”答非所问，文中未提及期刊接受问题。
