【正确答案】 1、正确答案： Yan Fu, a translator of Qing Dynasty, is famous for introducing western books to China by translating, in-cluding Thomas Huxley"s Evolution and Ethics and Other Essays(《天演论》), Adam Smith"s Inquiry into the Nature and Cause of the Wealth of Nations, John Stuart Mill"s On Liberty and Herbert Spencer"s Study of Sociology. Mr. Yan wrote in the preface to his translation of Evolution and Ethics and Other Essays that "There are three difficulties in translation: namely, faithfulness, expressiveness, and elegance(译事三难：信、达、雅)". Mr. Yan did not take them as general standards for good translation. However, since the publication of that book, the phrase "Faithfulness, Expressiveness, and Elegance" has been regarded as the triple criteria of translation in China, and it has given rise to numerous debates, including applause and criticism.
