短文填空专练 第2篇

主谓一致是历年高考热点之一,一般说来,句子的主语和谓语在人称与数上应保持一致,但在很多情况下存在一些特殊情况,这些特殊情况就是重要考点。本文以往年高考试题为例,对此考点作以归纳。

短文填空专练 第3篇

短文填空是在一篇语意相对完整的短文或对话中有目的地挖去一些需要考生掌握的重点词汇, 有意造成信息缺失, 精心设置阅读障碍, 综合考查考生运用英语语言知识的能力。考生需要在理解短文的基础上进行综合分析判断, 填出符合短文语境词汇的正确形式。由于短文填空属于有障碍性的阅读, 这些含有空缺单词的短文对学生来说困难较大, 历来是学生失分率较高的题型之一。

一、短文填空试题分析

1.导向清晰明确, 突出考查重点

以江苏省无锡市中考英语试题为例, 从2003年开始设置短文填空试题, 试题为:“先通读下面的短文, 掌握其大意, 然后根据短文内容和所给首字母, 在空格内填入一个适当的词, 使短文意思完整。 (本大题共12空, 每空0.5分, 共6分) ”2012年中考开始, 本题恢复为10空, 共5分。从对2008~2014年中考英语短文填空所考重点的统计表可以看出 (见表1) [2], 短文填空试题导向明确, 突出考查重点——实词为主, 虚词为辅, 主要集中考查考生对动词、名词、形容词和副词等的灵活运用, 而对连词、介词、代词等则考查甚少。

2.篇章阅读为先, 语境语法并重

短文填空首先强调的是考生的篇章阅读能力, 着重考查对语篇的整体理解。短文长度一般在180~200个单词, 生词量2%左右。[3]针对初中学生的实际水平, 一般采用故事体或说明文, 尽量避免专业性太强的文章或论文体。同时, 短文填空突出“词汇语境化”的特点, 充分体现了对考生综合运用语言能力的考查。考生要能根据所提示的有效信息大致猜到短文所要讲述的内容, 然后调用大脑中原有的知识图式, 根据上下文的语境推测出空格中应填的符合短文内容的单词, 并利用语法知识来修正单词的正确形式。例如:

短文描述的内容是魔方的发明经过。魔方起源于帮助学生了解三维概念的教室模型, 后来演变成流行的玩具。根据短文内容推理判断和分析后可以得出第7个空格应该和into构成短语turn into, 意为“变成”, 然后从“This classroom example was quickly t_________ (7) into a popular toy”推测出这里应该用被动语态。因此正确答案应为turned。

3.答案灵活开放, 训练思维能力

学生在做短文填空试题时, 根据短文内容和所给首字母, 在空格内填入一个适当的词, 使短文意思完整, 有时得出的答案并不是唯一的。因为不同的学生有着不同的生活阅历, 以及阅读短文的角度不同, 所得出的答案也许就不一样。为了训练学生的思维能力, 短文填空试题中的有些答案设置为半开放式, 只要符合短文的内容和上下文语境, 都予以采纳。例如:

The man with sunglasses entered the restaurant.“Good morning, sir!Welcome to Sunshine Restaurant.Can I help you!”“I’d like a p_________ (1) of beef and a glass of beer.”“Wait a minute, please!”The waitress went away quickly.

这是发生在饭店服务员和顾客之间的一段对话, 已知信息是顾客在饭店点菜, 在没有其他附加信息的情况下, 此题中以字母p开头的单词既可以填piece, 也可以填plate。又如:

(2008年中考题) Secondly, people move to the cities to find work, a_________ (5) there are often very few jobs in the countryside.Sometimes villages remain (留下) because people from the cities have b_________ (6) a“second home”in the village, where they come and s_________ (7) at weekends.

从文中信息可以得知, 越来越多的乡村人口到城市找工作, 乡村逐渐消亡。但是有些村庄保留了下来, 因为有些城里人到乡村买房或建房, 以便周末来乡下度假。所以文中第6个空格填bought或built都符合短文内容。又如:

(2011年中考题) Camels survive w_________ (9) in the desert, not because they can s_________ (10) water in their bodies though!They can survive without water for two weeks and without f_________ (11) for up to a month.

本文介绍的是骆驼可以在沙漠中很好地存活下来, 并不仅仅因为它们的身体可以储存足够多的水。所以文中第10个空格既可以填save, 也可以填store, 这两个单词都有储存的含义。

二、短文填空解题策略指导

1.整体阅读, 推断篇章主旨

短文填空不仅考查考生对英语语言知识的掌握情况, 还重点考查考生的语言综合应用能力, 如对短文的整体理解、逻辑推理及综合判断能力等。这种题型综合性较强, 要求考生运用所学的知识, 通篇整体考虑, 联系上下文, 在特定的语境中进行合理的推理判断。所以考生对短文有一个宏观的、整体的理解就显得至关重要, 包括短文的体裁、文章的主旨、作者的思路、情节的发展, 等等。考生在解答短文填空试题时, 不能一看到句子中的空格就急于下笔, 而是要整体阅读短文, 根据短文主题信息, 充分发挥想象, 调集大脑中储存的相关背景知识, 推断出篇章的主旨大意。例如:

(2013年中考题) On Thanksgiving Day, about88 percent of Americans eat turkey.But one l_________ (1) turkey not only survives but also becomes famous!Every year, turkey farmers p_________ (2) a turkey to the U.S.president…Turkeys don’t have ears.They h_________ (10) with a snood (肉垂) above their beaks.But their bearing is five times better than human’s.

通过整体阅读短文之后, 我们可以推断出这是一篇说明文, 文章的主旨大意是介绍感恩节火鸡。这样考生就能迅速建立起短文和自己大脑中知识图式的联系通道, 做到胸有成竹, 为后续填出空格中符合短文内容的单词打下坚实的基础。另外, 一篇文章通常有明确的中心主线贯穿全文, 运用阅读理解的“主题句”策略往往能够帮助我们快速找到短文主旨大意, 主题句一般位于文章的起始或结尾。例如:

(2010年中考题) The history of World Expos (博览会) started in Britain in the mid-19th century.At that time, Britain was the l_________ (1) of the Industrial Revolution (工业革命) .Many British people felt that it was i_________ (2) to show their achievements to the world.…BIE now decides which city should host e (12) Expo.In 2002, it decided that Shanghai should host the 2010 World Expo.

这篇短文“开门见山”, 一上来就运用主题句道出了本文的主旨大意。考生从第一句“The history of World Expos started in Britain in the mid-19th century.”就可推断出短文是介绍世界博览会的历史。

2.紧盯线索, 注意前后联系

短文填空的文章通常是一个鲜明主题所贯穿的信息链, 短文中的空格造成了信息链的中断。已知信息实际上就是未知信息的提示线索, 空格中的信息受到短文前后信息的制约。考生需要紧盯已知的、与空格内容相关联的信息线索来推断空格内的未知信息, 补全信息链。考生可以利用短文中的信息词、信息句来推断意思、理解提示线索, 弄清句与句、段与段之间的关系, 在全面理解整篇文章的基础上进行答题。[4]当然这些线索之间并不是完全独立分隔的, 而是相辅相成的关系。这些线索可分为词汇线索、句意线索和篇章线索。

(1) 词汇线索

有时, 我们可以通过句内或句外的词汇线索来直接找到答案。例如:

(2013年中考题) Turkeys living on farms are large birds that cannot fly.But w_________ (8) turkeys are quite fast.They can fly at a s_________ (9) up to 88 kilometers per hour.They can also run as fast as 40 kilometers per hour.

通过分析“at a s_________ (9) ”, 可以推测出文章中的第9空格应该填名词, 通过词汇“88 kilometers per hour”就能很容易地找到正确答案speed, 通过前一个句子中的词汇“fast”更加佐证了答案的正确性。

(2) 句意线索

未知信息的提示线索有时暗藏在前后的句意之中, 我们可以通过上下文句子的相互联系来找到正确答案。例如:

(2011年中考题) In many countries, people t_________ (1) by car or by bike.They also get from place to place using p_________ (2) transport such as buses and trains.However, some people live in parts of the world where it is i_________ (3) to build roads.In these places, animals or other f (4) of transport have to be used.

这篇短文讲述的是不同地区人们的不同交通出行工具。通过信息“They also get from place to place using p_________ (2) transport”可以得知第2个空格应该填形容词。但是不少考生迫不及待地下笔填了popular, 而没有仔细考虑文章前后句意的联系和上下文的提示线索“In many countries, people t_________ (1) by car or by bike.”和“using p_________ (2) transport such as buses and trains”。“轿车、自行车”与“公共汽车、火车”是一组相对应的交通工具:轿车和自行车属于私人交通工具, 公共汽车和火车是公共交通工具。因此, 通过句意线索综合考虑, 第2个空格的正确答案应为public, 而不是popular。

(3) 篇章线索

短文填空越来越趋向于考查句子、段落或篇幅意义, 所以未知信息的提示线索常常分布在整个意群、段落或整体文章之中, 这时我们需要考虑所填的信息不仅要满足句子和段落的连贯性, 还要在整个篇章的范围内来考虑所填信息是否符合文章整体的完整性、流畅性和准确性。例如:

文中第12空格作句子的主语, 应该填代词或名词, 不少考生单从本句进行分析就填了答案He。这个空格应从段落和篇章进行分析, 所填单词应该和本段中提及的Camels相对应, 用于替代文章中的people, 因此这个空格的答案应为Humans。

3.严格复核, 得意不能忘形

短文填空考察考生的英语综合运用能力, 不仅考查判断推理能力, 而且考查词汇、句型、句式、惯用法和语法等。考生通过整体阅读和紧盯线索, 找到符合文章意思的未知信息, 还要把单词带入到文章中进行严格检验复核, 仔细推敲, 分析所填的单词在句中充当的句子成分, 注意单词的形态变化, 如:主谓一致、动宾搭配、时态、语态、动名词、现在分词、过去分词、形容词和副词的比较级和最高级, 等等, 并特别关注所填单词是否符合文章上下文的联系。例如:

(2008年中考题) All these things mean that many villages in western Europe are f_________ (11) to survive.We can only hope that they will remain.The countryside would be a sadder and u_________ (12) place without them.

分析短文和句子得知, 第12个空格应为形容词, 找到单词ugly之后, 带回原文复核, 从句中信息“a sadder and u_________ (12) place”可知此空格应该和sadder并列, 是形容词的比较级形式, 正确答案为uglier。又如:

The eye-recognition (眼睛识别) program has already been t_________ (3) in shops and banks in the USA, Britain, Spain, Italy and Turkey.Soon it will take the place of all other ways of f_________ (4) out who people are.通过分析, 第4个空格应填动词和out构成短语find out, 把单词带回原句复核, 认真阅读全句后发现这个动词作介词of的宾语, 所以正确答案应为finding。又如:

Crime w_________ (2) a lot of people.Every year, the n_________ (3) of crimes goes up and up.They often come from sad homes, with only one parent or no parents at all.There are problems with drugs.

文中第2个空格应填谓语动词worry, 把worry带入文中复核, 通过上下文联系可以知道这个句子的时态是一般现在时, 主语Crime为第三人称单数, 正确答案是worries。

结语

短文填空考查的是考生的英语综合运用能力, 不仅考查其阅读理解推理能力, 同时也考查其语法知识的运用能力。因此, 考生在作答短文填空试题时, 首先要通过整体阅读短文, 推断出篇章主旨, 对短文有一个宏观的、整体的理解。然后分析已知信息中的词汇、句意和篇章等提示线索, 联系上下文, 判断所填单词的词性, 推测出空格内符合短文内容的单词。然后把单词带入文中进行复核, 瞻前顾后, 根据短语搭配、句型句式和语法等规则来变化单词的正确形态, 恢复中断的信息链, 做到语法正确、语用正确、语义正确和语境正确, 使短文意思完整、结构严谨和文理通顺。

第15题图

参考答案

1.4或8　【解析】由题可知，∵△ABP≌△CBP，∴点P一定处于正方形对角线BD上，∴共存在两种情况使△PBC为直角三角形，(1)如解图①，当CP⊥PB时，有PC2＋PB2＝BC2.又∵∠CBP＝45°，∴PB＝PC，∴BP＝4；(2)如解图②，当P点与D点重合时△PBC为直角三角形，BP＝BC＝8.第1题解图

2.3或6　【解析】如解图①，当∠AFE＝90°时，设BE＝x，则EF＝x，AE＝8－x，FC＝BC＝6，由勾股定理得AC＝＝10，∴AF＝10－6＝4，在Rt△AEF中，42＋x2＝(8－x)2，解得x＝3，∴BE＝3；如解图②，当∠AEF＝90°时，四边形BCFE是正方形，BE＝BC＝6.综上所述，BE＝3或6.第2题解图

3.5或6　【解析】如解图①，当PB＝PC时，点P是BC的中垂线与AD的交点，则AP＝DP＝AD＝3，在Rt△ABP中，由勾股定理可得PB＝＝＝5；如解图②，当PB＝BC＝6时，△BPC也是以PB为腰的等腰三角形．综上所述，PB的长度为5或6.第3题解图

4.1或7

【解析】∵△PDQ是等腰三角形，∴分三种情况：①如解图①，若点P在线段AB上，∠DPQ＝90°，∴PD＝PQ，∠APD＋∠BPQ＝90°，∵在矩形ABCD中，∠A＝∠B＝90°，∴∠APD＋∠ADP＝90°，∴∠ADP＝∠BPQ，∴△DAP≌△PBQ(AAS)，∴PB＝AD＝3，∴AP＝4－3＝1；②如解图②，若点P在线段AB的延长线上，PQ交CB的延长线于点Q，PD＝PQ，同理可证△ADP≌△BPQ，∴AD＝PB，∴AP＝AB＋AD＝3＋4＝7；③当P在线段BA的延长线上时，显然不成立，故AP的长为1或7.第4题解图

5.8或24　【解析】如解图①，∵BC＝6，BD∶CD＝2∶1，∴BD＝4，在Rt△ABD中，AD＝BD·tanB＝4×＝，∴S△ABC＝BC·AD＝×6×＝8；如解图②，∵BC＝6，BD∶CD＝2∶1，∴BD＝12，在Rt△ABD中，AD＝BD·tanB＝12×＝8，∴S△ABC＝BC·AD＝×6×8＝24.∴△ABC面积的所有可能值为8或24.第5题解图

6.13或14　【解析】分为两种情况：①如解图①，沿MN剪开，再沿CQ剪开(CD⊥AB于点D，MN为△ABC的中位线，CD交MN于点Q)，将△CQN放在△BFN的位置上，△CQM放在△AEM的位置上，由三角形面积公式得10＝×4×CD，解得CD＝5，∵MN为△ABC的中位线，∴CQ＝DQ＝CD＝2.5，∴矩形AEFB的周长为(2.5＋4)×2＝13；②如解图②，沿NQ、MT剪开(N、M分别为AC、BC中点，EQ⊥BA于点Q，FT⊥AB于点T，CD⊥AB于点D)，将△AQN放在△CEN的位置上，△BTM放在△CFM的位置上，由三角形面积公式得10＝×4×CD，解得CD＝5，∵N为AC中点，CD∥EQ，∴AQ＝DQ，同理BT＝DT，∴QT＝AB＝2，∴矩形EQTF的周长为(5＋2)×2＝14.故答案为13或14.第6题解图

7.3或　【解析】如解图，连接BM，DN，AN，得到四边形BNDM为菱形，∴BM＝MD，AM＋MD＝AM＋BM＝AD＝8，在Rt△ABM中，设AM＝x，则BM＝8－x，AB＝4，根据勾股定理得：x2＋42＝(8－x)2，解得x＝3，∴AM＝3，MD＝5.当PB和PD在BD上方时，点P与点M重合，则AP＝AM＝3；当PB和PD在BD下方时，点P与点N重合，由对称性得到PD＝ND＝BN＝MD＝5，在Rt△ABN中，AB＝4，BN＝5，根据勾股定理得：AN＝＝＝，此时AP＝AN＝.综上所述，AP的长为3或.第7题解图
