学员疑问：医学统考英语2012年阅读78题我选的D，答案是C
老师解答：阅读78题，定位原文“scientists need to be able to take off their labcoats sometimes and speak as concerned citizens. Some may feel uncomfortable with blurting the line between science and activism, but they should be aware that no one understands the risks better than they do and no one is better placed to give informed opinions.”（科学家有时也需要脱下实验室的工作服，以普通公民的身份发表意见。有些人可能会觉得难以明确区分科学与行动主义的界限，但他们应该明白，没有人比他们更清楚这些风险，也没有人比他们更有资格给出合理的见解。），选项D. do as concerned citizens do in protecting environment（如普通公民在保护环境方面所采取的做法那样去做）和原文 speak as concerned citizens（以普通公民的身份发表意见）不符，选项C. be definite enough to offer informed opinions（有足够的把握来给出合理的意见。）符合原文but they should be aware that no one understands the risks better than they do and no one is better placed to give informed opinions的理解。
