1、第一部分 Cloze for CET-4 完形填空专项 自信才能成功，而自信是建立在对事物深刻认识的基础之上的。第1页/共53页一、完型填空题的设计填空(Cloze)又称综合填空，其命题原理是格式塔心理学。格式塔心理学强调整体感知，完形填空测试的就是考生结合上下文的语境(context)对英语的整体感知能力。一篇完形填空测试考生什么能力,与短文空格设计密切相关。如果空格要求填连词、介词、冠词等，则空格为功能性空格；如果要求填名词、形容词、动词等实义词，则空格为语义空格。目前，完形填空试题的题目难度不断加大，重点从传统项目题逐渐转到对整体预感的测试和整个语篇的理解，根据上下文选择题目比例正在增大

2、。第2页/共53页一、完型填空题的设计 设计者遵循一定的要求和准则，以保证测试的信度和效度。约250250字的文章中每隔816字就有一个空，按照一定间隔并根据语法或词汇测试的标准设计的。这些空格表面看起来没有什么意义，实际上综合了词汇、语法结构以及阅读理解所要测试的内容，不仅测试在词汇和句子水平上运用语言的能力，还测试在语篇上综合运用语言结构的能力。完形填空中所填的词是与文章的上下文紧密联系的，难度较大，往往成为学生失分较严重的题项。第3页/共53页一、完型填空题的设计 从题裁看，完型填空涉及说明文，议论文等众多文体体裁，而内容更涉及到社会领域的方方面面，政治、经济、文化、教育、医学、天文、体

3、育、科技等等。所以考生具备大量的背景知识也是格外重要的。第4页/共53页二、完型填空题的做题步骤 完形填空实际上就是要求把每个句子中删掉的词恢复出来。因此，要做好完形填空，必须要在通读全文、把握结构与大意的前提下，根据所提供的选项及句子的结构、语法、语篇等信息，通过逻辑推理、对比等手段确定答案。根据完形填空这一测试特点，一般采取以下五个步骤进行。第5页/共53页步骤1，通读全篇，把握总体，了解知识背景。注意：去掉20个空不影响对整篇的理解，短文的前1、2句话不设题。细读文章首句，可以判断体裁、把握背景、推测大意、主题或结构。在阅读文章的过程中，学生积极搜集头脑中已有的相关知识，结合文章内容形成

4、对文章的整体把握，称之为图式(schema)，它能够帮助猜测文章内容，能够简化推断，并在阅读中，不断修正，以求与原文一致。比如，第6页/共53页Three girls went walking in the woods.They were enjoying themselves so much that they forgot the time and stayed too long.A dragon kidnapped them.As they were being dragged off,they cried for help.Three heroes heard the cries an

5、d set off their horses to rescue the girls.接下来是什么呢？猜测内容 第7页/共53页 Possible result:The heroes came and fought with the dragon and rescued the girls.Then the heroes returned the daughters to their places.Maybe,you can guess that the three girls married the three men respectively.如果熟悉文章，那么文章内容与你头脑中的图式相结

6、合，解题会势如破竹。又如：第8页/共53页 Writing in a diary,watching television,talking with friends,speaking on the telephone,and reading a menu-what do they have in common?.Thus,_ may be defined as the means by which people exchange feelings and ideas with each other.A.information B.learning C.communication D.acquis

7、ition 第9页/共53页步骤二，选择答案。两种方法：1，不看选项，猜测答案，在选项中选择最接近自己猜测的一项。2，将选项带入空格内检测。按照先易后难原则，先选出根据上下文就能确定、直接、明显答案。增强信心，减轻心理压力。再瞻前顾后，不要忘记首尾照应。要牢记文章中心思想，每个空白处的含义应与前后句的意义联系起来。第10页/共53页步骤三，为不确定答案寻找线索 前面空格有可能要到文章末尾才能找到答案。所以对难度颇高的空格要在字里行间寻找线索。一定要上下连贯，合乎逻辑。步骤四，返回补缺 在一个题上不要耽误太多时间，先暂时放过继续做下面的题，等通篇做完后再回头考虑这个选项。切忌，一定要保证思维的连

8、续性和统一性。第11页/共53页 步骤五，核实答案 1)所选是否符合本句内容，上下文连贯？2)所选是否符合某种固定搭配？3)所选是否符合某种句型、时态、语态的特殊要求？4)所选本身或附近的词有无特殊要求，如有些动词后面只接动名词而不能接不定式。5)保持自信，不轻易否定所选。必要时对个别答案推敲，发现不妥，重新考虑，但应慎重，无确实把握，仍应相信第一印象。第12页/共53页完型天空题的考查内容？第13页/共53页词汇：四级完形考察词汇不外乎同义词、反义词、形近词，和词的精确用法。我们应该了解高频词的近义词、反义词，形近词和词汇的基本义。例如，1)Geographers compare and c

35、e B comfortable C convenient D available第37页/共53页5：同现 词汇的同现关系指词汇共同出现的倾向性。在语篇中，围绕一定的话题，一定的词往往会同时出现，这些词语属于同一个词汇套，形成词汇链，遇到其中一个词语，根据情境便会联想到词汇套中的其他词语。比如，提到教室一词，下面出现的词可能就是：blackboard,desk,students,chair,floor,lights,etc.blackboard,desk,students,chair,floor,lights,etc.第38页/共53页 例1：My grandmother worked har

39、接外，还运用到一些句与句之间的连词来表达并列、转折、对比、列举、原因、结果、让步、补充等关系。常考的连接词：第42页/共53页表示并列关系的：and,on the one hand,on the other,表示转折关系的：however,nevertheless,still,though,yet,in spite of,at any rate,in any case,etc.表示对比关系的：on the contrary,in contrast,by contrast,in comparison,by comparison,conversely,表示补充关系的：also,further,fu

44、不要题海战术，四六级内容知识量有限，过多的新知识让人失去信心学会研究题目，举一反三词汇是基础，语法是支撑点两者兼顾要学会学习的迁移无论考试的哪一项，其实都是考察学生的综合能力。第47页/共53页第48页/共53页第49页/共53页 A Pelican holds many fish in its 71.72 may last a 73,but they wont last a week.A pelican is nearly as tall as you,and its beak is as long as your arm.A long skin sack,or pouch,hands do
