大学英语精读5课后翻译答案(第三版)

Unit 1 Mastering a large number of words is essential to achieving fluency in a foreign language. An unofficial, but often quoted, figure for the Cambridge First Certificate examination suggests that students with a vocabulary of less than 3,500 words are unlikely to be successful in the exam. Current research also suggests that native English speakers who have been educated up to 18 years old or beyond know at least 16,000 English words. And unless you already speak a language like Spanish or German, there are no shortcuts to a large vocabulary in English: you just have to rely on diligence and dedication. Of course you can figure out from the context the meanings of some new words you come across in your reading, but more often than not you have to look them up in a dictionary in order to be clear about their accurate meanings. A practicable way to pick up new words is, perhaps, to read a lot, preferably stories that you find interesting or exciting. It often pays to read the same book over and over again: each time you read it you will learn different new words, and the familiar context helps to fix them in your mind.Unit 2 1.

Regardless of repeated warnings from his friends, he staked all his money on high-risk ventures.Unit 3If you st arted on some venture and failed, do not despair/lose heart. There is a world of difference between “ I have failed three times” and “I am a failure”. So long as you do not hold a negative concept of self or identify with failures but try t o learn from them, you stand a good chance to succeed in the future. Does it ever occur to you that those who fail repeatedly are often victims of a poor self-image? Often their failures are due to internal causes rather than external causes. Numerous cases have borne it out that if they can be induced to change their viewpoint and construct a positive self-image, miraculous changes may take place in their performance. Success can come anytime --- at thirty, forty or even after a lifetime of apparent failure. Early triumphs may be sweet, but success in later life often tastes even better.Unit 5Scientists are a small group of people who strive to gain insights into nature, seeking order in seeming disorder. They are credited with a special ability to think and analyze, and with infinite patience in making observations and collecting data. But ability and patience do not account for all scientific discoveries, which often have much to do with creative imagination. Indeed a leap of imagination is often the first step towards discovery. Scientists are also noted for their honesty. They place a high premium on honesty largely because it is essential to their career. Every theory they formulate is subjected to further testing. Every mistake or lie is bound to be found out. Therefore if any evidence is found contradicting their ideas, scientists do not suppress the evidence but modify or even abandon their ideas. In this way they have built up an immense body of knowledge, which helps us to understand better ourselves and the world around us. Unit 6One day, we received an invitation to my father’s birthday party. Jenny thought my father was reaching out to me for a reconciliation and we should accept the invitation. I was in the midst of abstracting an important case and in the virtual shadow of exams, so I just told her in the simplest terms that there would never be a reconciliation. My refusal obviously made Jenny very upset, but being a rational woman she didn’t quarrel with me. She just tried hard to persuade me. But this only filled me with fury, thinking that Jenny was just upsetting me deliberately. I must have gone out of my mind for I did something for which I would never forgive myself --- I yelled at Jenny and hurled the phone at her. But the instant I did it I regretted. And when I turned to look at her, she was already gone.I went out and searched everywhere but Jenny was nowhere to be found. I was scared to death, not knowing what to do next. Just as I was about to give up, I caught sight of her sitting in front of our house. I went up to her and said, “Jenny, I’m sorry…” but she cut off my apology and said, “Love means not ever having to say you’re sorry.。
