完型填空填空命题课件.ppt

1、完形填空完形填空题主要有两种形式：fixed-ratio cloze 和 modified cloze。Fixed-ratio cloze是完形填空最初所采用的形式，它要求“每隔几个词随机去掉一个词”，即使这个词是专有名词也毫不含糊。Modified cloze 是在 fixed-ratio cloze 的基础上发展起来的，与其不同的是，Modified cloze 要求去掉其一特定词类或任何一个我们希望去掉的词。Modified Cloze 又可分为 MC cloze,Bank Cloze,C-cloze 和 Open cloze。MC Cloze是指每题给出一组选项（一般为3或4个）的完形

2、填空题；Bank cloze 是指“各题给出同一组选项的完形填空题”；C-cloze 是指“将空缺处单词去掉几个字母的完形填空题”；Open cloze则是指“去掉短文中的某些单词，但不给出选择项的完形填空题。现在，因各种不同的原因，大家都倾向于使用MC cloze。完形填空完形填空（Cloze）又称综合填空，是标准化出题方式的一种常用形式，其理论基础是格式塔心理学，格式塔心理学强调知觉、思维和动机的结合。在英语测试中强调“语感”，即考查学生阅读理解和语言知识的综合应用能力。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的什么能力，这与短文的

3、空格设计密切相关。如果空格要求学生填入连词、介词、冠词等，则空格为功能性空格；如果要求填入名词、形容词、动词等实义词，则空格为语义空格。从近几年的高考试题看，完形填空以语义空格为主，主要测试考生的阅读能力和总体水平。但最近命题专家将完形填空分为四种类型：词内项、词间项、句内项、句间项,并据此确定各项的构成比例而命题。上述四项试题的难度依次递增,近年重点考后两项。完形填空（二）完形填空是综合性题型，既考查词汇知识，也考查阅读理解能力。要以考查动、动词词词组、形容词、副词、名词等实词，并要抓动、动词词词组、形容词、副词、名词等实词，并要抓住语境、上下文与考点的联系来设题。住语境、上下文与考点的联系

9、结构等的含量。上下文关系应较为紧凑各类英语考试的完形填空均较为明确地确定了inter-sentential试题的比例，因此所选文章的结构应该比较紧凑，以利于出一些上下文理解的试题。完形填空命题题根据新大纲规定，完形填空满分为高中20-30分，共有20个空；初中10分，共有10个空。短文长度为高中240-280 个词左右，初中150-200个词左右，每空1分。每个空即为1个题，每个题有3-4个备选答案，主要测试词汇、语法和结构，以单个词为主，词组为辅。词汇主要是考查内容集中在考生对名词、动词、形容词和副词等实词的理解上。B挖空所应遵循的一些原则对考生来讲，短文的第一个句子起着让他们熟悉语言环境的

10、作用，不应挖空。如果这个句子是个长长的并列句，可以考虑在后一分句挖空。各类试题应均衡分布试题所考查的语言点应均衡分布。例如，介词和副词容易挖空、做题，但该类试题在数量上应受到一定的限制。各类试题均规定了试题类型的比例，20个试题中应有12个词汇题、8个词汇一语法题。总而言之，试题应该有较大的覆盖面。并且单纯的语法题几乎从该题型中消失，如果一味按照语法规则来选择答案，就陷入了答题误区 刚才，我们从词汇和语法等角度谈了试题测点的分布。此外，我们还应牢记，单句层次和句子间层次、段落层次试题也应该规定一个比例。从近几年的高考原题来看，近义词或词组的辨析正成为考试的热点。四个选择项或都是词义相近的名词单

11、数或复数，或都是近义动词的同一时态等，只能根据上下文的语境做出正确的选择。如果提供的四个选择项词义相差悬殊，则上文或下文肯定有答题提示，有时第一个空格要读完全文才能回答。完形填空整体命题思路认真阅读文章、抓住文章的中心、主旨大意、作者意图、幽默点、交际点抓住文章各部分的主要内容、要点关键句上下文的联系（句间项）句内个部分的联系（句内项）完形填空题设题判断的依据(1)环境线索Im tired of sea food,so I didnt eat much_ that day.（答案B）A.vegetables B.flounder（比目鱼）(2)因果线索He was badly ill,so h

27、短文的大意，然后再设题，这种题一般12处。题目设置上单纯语法考查减少，上下文联系考查力度加大，并且以同义词、相似词为典型的迷惑选项增多。但要注意：不是靠同义词细微辨析，而是通过上下文逻辑分析，得出结果，靠用法和搭配得出答案。干扰选项设计根据句意和上下文学生有可能发生的错误理解,因此正确选项与干扰项意义相差悬殊.根据常识推理有可能发生的错误选项.根据语篇有可能发生的错误推理.英语意义相近,句意限制英语意义相近,用法限制英语意义相近,用法有异.英语意义相近,常识限制英语意义相近,搭配不同汉语意义相近,英语意义不同注意避免:意义以及内涵包容与重叠 Englishvocabulary,pronunci

34、表现为长句、复合句增多、句子结构复杂(定语从句、状语从句、插入语等)、句式丰富多样(陈述句、祈使句、省略句、疑问句、感叹句等)，极大地增加了阅读难度，限制了学生的理解程度。如：(NMET2001)The native people said they 38 this creature and called it theYeti,and they said that they had 39 caught Yetis on two occasions 40 none has ever been produced as evidence.又如：(NMET2002)I had an auto-repa

39、ou need to find out whats really important to you and make a choice我们从词汇和语法等角度谈了试题测点的分布。此外，单句层次和句子间层次、段落层次试题也应该规定一个比例。比例随年级变化，低年级单句层次高一些，以后过度到以句间层次为主，一般段落层次1015%，句子间层次占70-80%。试题在短文中应该均衡分布这儿，我们指的是各空之间的距离应大致相当，不要有的两个题之间相隔十几、二十几个词，而有的两个题之间仅相隔两个词。应尽力避免相互依存的试题命题时应设法避免挖空两个关系过于密切的单词或短语，否则答错一个题即意味着两个题全错，反过来

40、，答对一个题亦意味着两个题全对。这样，其中一个考点已基本发挥不了什么考查作用，根本没有存在的价值。这类相互依存试题在距离上一般都靠得太近。如：Wait till youre more certain.Its better to be sure than sorry.应尽力避免正确选项出现在短文的其他地方，给考生以下该给的方便。如果确实不得不挖去某个词，而该词又出现在文章的其他地方，可以设法改换另一个词，否则可能只有舍弃这个考点。挖空短语时应注意正确项与干扰项形式上的一致1、A.hardly 6+B.never C.nearly D.seldom(little)考查对动词短语的掌握，可以只挖空动

41、词，可以只挖空动词后的介词或副词，也可以挖空整个短语。挖空整个短语前，应充分考虑能否找到三个同样结构的干扰项。选 项下面看一下编制完形填空各项应遵循的几条原则：正确答案必须是从短文中挖掉的那个词或短语，必须为唯一正确选项每个题只能有一个正确答案，命完题后应从各个角度观察，确保任何干扰项在任何情况下都不会成为正确答案。干扰项必须有一定的干扰性干扰项的选择应该有某些可靠的依据，应该属同一类型，例如他们可属于同一语议范畴，在语法上属于同一词性，看起来似乎都可以填入空缺处。英汉两种语言的对比结果也是选取干扰项的一个不错的途径，有些英语水平稍差的考生往往搞不清楚英汉两种语言在一些语言点上的异同，而将汉语

42、中的某些构错误地套用到英语上。应该注意的是，不要让任何一个选项与其他选项明显不同，而影响考生的选取。从统计指标看，任何一个选项都必须有至少5%的考生选取，否则就是一个不理想的选项，就需进行修改。“My names Jim Shelley and Im an addict(有瘾的人)”With these words I began to 36 the problem,the problem of my telephone addiction.I used to call people 37,from the moment I woke up to the time I went to slee

46、者设计完一个干扰项后，会不经意地设计出两个意义上更接近于干扰项后，会不经意地设计出两个意义上更接近于这个干扰项的干扰项，如：AConsists(key)BComposes(distractor for A)CWrites(distractor for B)DExpresses(distractor for B)这样，三个干扰项几乎都失去了干扰作用，当然，这也就在一定程度上违背了第二条原则，因为A与其他几项明显不同。当四个平行的选项实在难以找到时，可以设法找两平行的选项。如果连两对都难以找到，那就说明该点不适于作为MC类试题的考点。干扰项不应相互包容各选项不能够互相包容，否则就会出现正确选项突出

47、（包容项为干扰项时）或有两个正确答案（包容项为正确选项时）的情况。如：A.desk B.furniture C.box D.piano。完形填空试题的最大特点是考查学生根据上下文的意思和逻辑联系进行推理、判断的能力。学生每填一个空都需要从上下文寻找线索。但是考试题不符合这一命题要求。is an old city with a 36 of more than 2,100 years.It is in the 37 of the province on the northern banks of the 38 River,and is a link between northern and 39

49、不仅把一些非语言知识的内容作为了考查点，而且还把专有名词挖空。从语言测试的角度来看，这道题的信度和效度都比较低。One day there was an argument between the wind and the sun.“Im much 71 than you.”said the wind.“No.I dont agree with you.”said the sun.While they were arguing,they saw a man 72 along the road.He is wearing a heavy coat.The sun said to the wind,
