【篇一：大学英语精读5课后翻译答案】

量的词汇对于达到一门外语的流利程度是至关重要的。一个非官方的但却是经常被引用的有关剑桥处级证书英语考试cambridge first certificate examination的数字表明，词汇量少于三千五百词的学生不大可能在这项考试中成功。最近的研究也表明，其母语为英语的受教育至18岁或18岁以上的人至少认识一万六千个英语词。除非你已经会讲一种像西班牙语或德育这样的语言，要获得打的英语词汇是没有捷径可走的：你就得依靠勤奋和专注，当然，你可以从上下文猜出你阅读中遇到的一些生词的意思，但往往你得查字典才能搞清他们的确切意思。一个切实可行的学习新词的方法或许就是大量阅读，最好是读那些你觉得有趣或刺激的故事。反复阅读同一本书常常是很有好处的：你每赌一次都会学到不同的生词，而熟悉的背景又有助于将这些新词牢牢地印在你的脑海中。

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.

如果你着手干一番事业而失败了，不要丧失信心。“我失败了三次”与”我是一个失败者“之间有着天壤之别。只要你对自己不持否定的想法，不把自己与失败等同起来，而是试图从失败中吸取教训，你很可能在未来取得成功。你可曾想过，那些屡遭失败的人往往是自我形象不佳的牺牲品？他们的失败常常不是由于外部原因而是内部原因。无数的例子证明如果能劝使这些人改变观点并建立起正面的自我形象，他们的表现就会发生奇迹般的变化。成功可能在任何时候到来—三十岁，四十岁，或是在似乎失败了一辈子以后。早年成功固然甜蜜，但是晚年的成功往往更有滋味。
