何凯文考研英语教你如何分析句子

考研英语长难句结构拆分技巧考研英语长难句结构拆分技巧一、从状语等修饰语的角度出题考研英语阅读的文章句子一般较长，出题人往往只从句子当中的某一个成分处设题，特别是定语成分和状语成分。

例如：Still，Jefferson freed Hemings‘s children —though not Hemings herself or his approximately 150 other slaves. Washington，who had begun to believe that all men were created equal after observing the bravery of the black solders during the Revolutionary War，overcame the strong opposition of his relatives to grant his slaves their freedom in his will. Only a decade earlier，such an act would have required legislative approval in Virginia.40. Washington‘s decision to free slaves originated from his[A] moral considerations.[B] military experience.[C] financial conditions.[D] political stand.【解析】题干问的是华盛顿给奴隶自由的决定是源于什么，也就是问原因，显然我们需要找原因状语的分。

文中最后一段的“Washington，who had begun to believe that all men were created equal after observing the bravery of the black solders during the Revolutionary War，overcame the strong opposition of his relatives to grant his slaves their freedom in his will.”明确指出是因为：after observing the bravery of the black solders during the Revolutionary War，华盛顿才做了这个决定，所以答案选[B]“军事经历”。

原来是因为这些原因，我们才不会分析长难句

许多同学在复习长难句时，发现自己不是特别能分析好长难句。

这很有可能是因为以下几个原因。

首先，不清楚英文转化为中文过程中真正的障碍是什么——是语义和语序。

分析长难句时，往往还受汉语语序影响，不能从英语语序的角度分析。

何凯文老师2017《考研英语长难句解密》对长难句都有中文翻译和解析，让我们能更加清晰地了解语义和语序。

其次，没有一个完整的语法体系。

对英语语法认识不够清晰，没有形成完整的语法体系。

何凯文老师2017《考研英语长难句解密》在讲解长难句时，也从从句等语法角度编排内容，让我们不仅了解长难句，而且也进一步完善我们的语法体系。

再次，没有学会识别句子中的障碍。

何凯文老师的2017《考研英语长难句解密》讲解清晰，让我们能逐步了解和识别句子中障碍。

最后，练习也没有形成体系。

何凯文老师的2017《考研英语长难句解密》中，就有充足的例句，帮助我们多复习，提高对长难句的掌握。

相信通过我们的努力，我们一定可以复习好长难句的。

掌握好长难句，我们要这么分析来源：文都图书考研英语中，常常会通过对长难句的考查，了解考生真正的英语实力。

所以，我们在复习的时候，一定要花时间、花精力复习好长难句。

何凯文老师的2017《考研英语长难句解密》中，就从分析句子、解释重难点单词、介绍短语、翻译等多方面，让我们充分掌握好长难句，下面就通过一个句子的举例，让我们了解一下怎样分析好长难句，才能让我真正掌握好长难句。

I have excluded him because, while his accomplishments maycontribute to the solution ofmoral problems, he has not beencharged with taskof approaching any but the factual aspectsof those problems.【分析】多重复合句。

句子主干为I have excluded him，句中him 指代上句中的the average scientist“普通科学家”，翻译时需明确。

because引导原因状语从句，其中又嵌套一个while引导的让步状语从句。

句末of approaching…作task的后置定语。

整个句子顺译。

【点拨】1、名词短语the solution of moral problems 可以直译，也可译为动宾结构“解决道徳问题”。

2、根据上下文be charged with a task，be charged with 应理解为“承担(任务)”，而不是常见意义“指责，谴责，控告”。

3、approach的含义较多，句中其宾语为the factual aspects …，因此可译为“触及”、“研究”。

4、固定结构not…any but相当于only,表示“仅仅”。

【译文】我把普通科学家排除在外，是因为尽管他的成就可能有助于解决道德问题，但他承担的任务只不过是1研究这些向题的事实层面。

把握命题命脉，直击选项本质何凯文“考研场上我们经常会遇到这样的情况，通过回文章定位，根据对原文的理解我们能很快的排除两个选项，而剩下的两个选项会把我们折磨的死去活来。

也就正是这种选项间微小区分度构成了考研英语的特色。

每每在甄别选项的时候，我们总会觉得这两个选项都对，并且会觉得自己的答案比给出的正确答案更为合理。

而考研英语作为全国人才选拔性的考试，并且会向社会公布标准答案的考试，在答案的设置上一定是合理且正确的，并且这种答案的设置是有一定逻辑线索的。

否则，这种人才的遴选是没有意义的。

而这种线索就是我们在标题中提到的命题命脉，这种命脉就会体现在选项之上。

本文正是要带领考研战士们去探求这种命题命脉在选项上的体现。

首先来看几道例题：2009年考研阅读第四篇文章第一题The most thoroughly studied intellectuals in the history of the New World are the ministers and political leaders of seventeenth-century New England. According to the standard history of American philosophy, nowhere else in colonial America was “so much importance attached to intellectual pursuits.” According to many books and articles, New England’s leaders established the basic themes and preoccupations of an unfolding, dominant Puritan tradition in American intellectual life.1. The author holds that in the seventeenth-century New England ____.［A］Puritan tradition dominated political life.［B］intellectual interests were encouraged.［C］Politics benefited much from intellectual endeavors.［D］intellectual pursuits enjoyed a liberal environment.根据题干中的seventeenth century 和New England 我们不难定位到文章的第一段，选项A 中的Puritan tradition（清教传统）在倒数第一句中出现，但是倒数第一句是这样说道：“大量的文章和书籍都记载道，新英格兰的领袖们确立了美国知识生活中的基本话题，其最关注的就是一直在知识生活中占据主导地位，并不断演进的清教传统。

何凯文考研英语阅读技巧Certainly! Here's an article on He Kaifeng's test-taking strategies for postgraduate English reading:Mastering the Art of Postgraduate English Reading with He Kaifeng's TechniquesPostgraduate English reading is a critical component of the entrance examination for prospective graduate students in China. He Kaifeng, a renowned English educator and author of the "He Kaifeng Postgraduate English Reading" series, has developed a set of strategies that have helped countless students excel in this area. Here are some of his key techniques:1. Understanding the Structure of Reading Comprehension Passages- He Kaifeng emphasizes the importance of recognizing the structure of a text, which often follows a logical order. By identifying the main idea, supporting details, and the conclusion, students can better comprehend the passage as a whole.2. Skimming and Scanning- Before diving into the details, He Kaifeng advises students to skim the passage to get a general idea of thecontent. Scanning, on the other hand, is used to locate specific information within the text quickly.3. Identifying Keywords and Phrases- Keywords are the building blocks of a passage. He Kaifeng suggests that students should be adept at identifying these, as they often signal the main points or the author's intent.4. Dealing with Vocabulary in Context- Encountering unfamiliar words is common in reading comprehension. He Kaifeng's approach is to use context clues to infer the meaning of these words, which can often be deduced from the surrounding text.5. Mastering Inference Questions- Many questions in postgraduate English reading require inference. He Kaifeng recommends students to look for clues in the text that suggest the author's opinion or the implications of the information presented.6. Practicing with真题 (Real Exam Questions)- He Kaifeng insists on the value of practicing with past exam papers, known as 真题 in Chinese. These real exam questions provide insight into the types of questions asked and the level of difficulty expected.7. Developing a Time Management Strategy- Time is a critical factor in exams. He Kaifeng advises students to allocate their time wisely, ensuring they have enough time to read through the passage and answer all questions.8. Reviewing and Learning from Mistakes- After completing practice exams, He Kaifeng encourages students to review their mistakes and understand why they were made. This self-assessment is crucial for improvement.9. Broadening Reading Materials- To enhance reading skills, He Kaifeng suggests that students read a wide range of materials, including newspapers, magazines, and academic journals, to familiarize themselves with different writing styles and subject matters.10. Maintaining a Regular Practice Schedule- Consistency is key to improvement. He Kaifeng recommends a regular study schedule that includes daily practice sessions to keep reading skills sharp.By incorporating these strategies into their study routine, students can significantly improve their performance in postgraduate English reading sections. He Kaifeng'smethods are not just about passing an exam; they are aboutdeveloping a lifelong skill for understanding and analyzing written English.。
