单选题 As ordinary people, scientists are by no means more honest or ______ than other people, but as scientists, they attach special value to honesty while they are in their working sphere.
A. ethical B. ethnic C. aesthetic D. esthetic

【正确答案】 A

【答案解析】[解析] A项“ethical道德的”符合题意。如：The lawyer alleged that the doctor's behaviour had not been ethical. (律师声称那位医生的行为不符合职业道德规范。)其他三项“B项ethnic种族的；C项aesthetic审美的，美学的；D项esthetic感觉的”都不正确。本题空格处是说比其他人更诚实或更有道德。因此A项为正确答案。
