There are two ways in which we can think of literary translation: as reproduction and as recreation. If we think of translation as reproduction, it is a safe and harmless enough business: the translator is a literature processor into which the text to be translated is inserted and out of which it ought to emerge identical, but in another language.
But unfortunately the human mind is an imperfect machine, and the goal of precise interlinguistic message-transference is never achieved; so the translator offers humble apologies for being capable of producing only a pale shadow of the original. Since all he is doing is copying another’s meanings from one language to another, he removes himself from sight so that the writer’s genius can shine as brightly as may be. To do this, he uses a neutral, conventionally literary language which ensures that the result will indeed be a pate shadow, in which it is impossible for anybody’s genius to shine.
Readers a
A. degree of subjectivism.
B. the rules of translation.
C. linguistic skills of the translator.
D. the reading of the work to be translated.

[填空题]When Nick A. Coreodilos started out in the headhunting business 20 years ago, he had a keen eye for tracking talents. From his base in Silicon Valley he would send all-star performers to blue-chip companies like Xerox, IBM and General Electric. But while he would succeed in his part of the hunt, the job-seekers he located would often fail in theirs. They were striking out before, during or after the interview.
So instead of simply hunting for talent, Corcodilos began advising job candidates as well. He helped improve their success ratio by teaching them to pursue fewer companies, make the right contacts and deliver what companies are looking for in an interview. In his myth-busting book, Ask the Headhunter (Plume, 1997 ) , Coreodilos has reinvented the rules of the job search, from preparation to interview techniques. Here are his six new principles for successful job hunting:
41. Your resume is meaningless.
Headhunters know a resume rarely gets you inside a com
