1、关键信息识别与浓缩,关键信息识别,信息单位:语句根据其信息分布情况分为信息单位,小句(clause)常被看作一个信息单位 信息焦点:每一个信息单位中必然有一个负载最重要信息的成分,即 “信息焦点”.它是说话人想要重点强调的信息,主要是新信息. 英语单句的焦点常在句子的尾部,即末尾焦点(end-focus)原则. 除焦点信息外,还有比较新的信息,称为重要信息 关键信息包括焦点信息和重要信息,主要指焦点信息,关键信息识别,E.g. A. That he has kept talking about the heavy traffic to explain why he was late again
2、 is obvious. B. It is obvious that he has kept talking about the heavy traffic to explain why he was late again. (信息焦点) A句比较累赘,听话人很难准确及时理解信息,而B句遵循了次重要信息(obvious)到重要信息(he was kept talking about the heavy traffic),再到最重要信息(to explain why he was late again)的逐渐深入的原则,相对容易理解.听话人在一定的旧信息基础上理解(半)新信息,最后理解焦点信息,
3、符合人们的认知规律.,关键信息识别,一般情况下,除强调句和倒装句外,英语单句信息的分布顺序是:从一般到特定、从泛指到特指、从已知到未知、从次重要到重要、从旧信息到（半）新信息，再到信息焦点。,关键信息识别,E.g.

10、量相对较少，且可以通过主语、宾语推理出来 因此：四大成分所承载的信息重要程度依次是：宾语或补语，主语、谓语。（符合英语句子末尾焦点原则） 一般来说（除主谓句外），句子信息分为：次要信息（定语、谓语、状语）、重要信息（主语、定语、谓语、状语）和焦点信息（宾语、补语） E.g,句子信息分布与句子成分,Past experience demonstrates that a partnership between China and the United States is beneficial to both nations.
