首字母填空技巧整理

1、首字母填空技巧整理整体思路：首字母填空类短文题是近几年各省、 市中考题经常采用的题型之一， 这种题难度相对较大，考 生失分现象很严重。主观型首字母填空也称为限制型完形填空。它的特点是将一篇文章中若干个词“掏空”，留下 该词的首字母，它既作为提示又作为限制，让我们根据短文的意思把单词拼写完整，使文章连贯。 学生们在通读全文、掌握大意的前提下， 采用先易后难，再逐项填空的应试策略。做题时要通过字 里行间来捕捉信息，既要理清逻辑， 又要综合考虑，最后通过复读全文来消除疏漏。给首字母填空 类短文的阅读题属于能力测试的范畴， 它考查的范围极广，可以是英语知识的方方面面，还可能涉 及其它学科。它要求考生在

2、充分理解短文的基础上将单词拼写出来，并且单词形式合理，符合语法规范，符合短文需要。下面就讲一讲做这类题的方法与技巧：1 .通读短文知大意，看整体全面了解 I !."与阅读理解题和其它类型的完形填空一样， 首先要通读短文；了解文章的大意。每篇短文段落 之间必然承上启下、前呼后应。因此通读全文时要一气呵成，只要能了解短文的大意即可，细节不 理解可以跳过。因此，在解题之前通读一遍短文，目的是对文章有个全面的了解，弄清其中心思想 和大意。2 .复读短文抓信息，前后照应巧猜词在了解文章大意的前提之下再次通读短文， 目的是对短文有更进一步的了解。 在阅读时要特别 注意一篇文章的开头（一般不设空）

3、 和结尾，它们能提供主要的信息，帮助了解全文所描述的事件 或文章的中心思想。在阅读过程中，要注意上、下文的关系，这对于把握文章的整体意义大有用处。 另外，要学会跳读，即对不理解的地方采用暂时回避的方式，待真正理解全文之后再找解决的方法。 有些短文填空题，有时出现约 3%5%的生词是很正常的，这就要求学生根据构词知识或上、下 文的意思加以猜测，来确定它的词义。I i ''J I.3 .反复推敲多分析，慎重答题讲技巧I i再次通读短文，对留空的句子进行全面的分析，看它在全文中所处的位置、作用和意义。 这一 遍阅读要求是精心阅读，要留心找出关键词、短语或句子，还要结合所给首字母的提示

4、，进行填写， 并注意单词的正确形式。4 .认真复查全文，把握整体和词形做完以后，再认真读一遍，检查所填写的单词是否与文章要求相符，文章是否通顺，前后是否呼应，有无句型结构及语法错误。从实际中看，很多学生能够充分利用词首字母和短文内容填写单 词，但是，问题往往出现在单词的形式变化上。比如填 q ,要求填写quickly ,而多数考生只知 道填写quick ,忽略了词性问题。因此，深思熟虑很重要。通过以上对首字母填空类型题的讲解，同学们一定对这类题型有了更多的了解，掌握了此类题的考点和做题的技巧后，给同学们准备了以下的练习题，请同学们及时巩固学习内容。例 1: Read the passage a

5、nd fill in the blanks with proper words:(在短文的空格内填入适当的词， 使其内容通顺。每空格限填一词，首字母已给)A: Hi, how are you?B: Fine, thanks. Yesterday morning I saw your father in the street, I went up to takl to him, but he said he didn't know me. I was confused.A: It c_(1)_ be him! My father was at home studying English

6、at that time.B: Oh, sorry! I must have made a mistake. But why is your father studying English now?B: What a pity! He should have studied English really hard if he often goes to English-speaking countries.A: You're right. Now he is studying English b_(6)_ listening to tapes.l " . 7，"B:

7、 Good. By the way, are you free tonight? How about having dinner and then see the latest 3D m_?A: OK, that's great! See you later.1.2.3.4.5.6.7.Key: 1. can't ( couldn't)2. improve 3. lost 4. hungry 5. if 6. by 7. movie首字母填空小技巧：揣测句意(结合语境)(1) It c_(1)_ be him! My father was at home studyin

8、g English at that time4上篇完型中我们讲至U了 符号的重要性，此处各位注意找一下，关键符号“！ ”，我们知道感叹号可以表示惊讶、非常肯定 等，我们在把视线移到后半句，我的爸爸那个时候正在家里学习英语，结合两者，我们可以确定“那 不可能是他"，应该用can't来表示不可能(3)、 (4)、 (5)需要结合起来来看，Once he was almost l_(3)_. And when he felt h_(4)_, he even didn't know i_(5)_ there's a good place to eat.先我们要知道 O

9、nce是什么意思， 这里的 once 解释为曾经，然后我们又可以发现在后半旬开头有个And,前后句子之间存在着并列关系，他曾经几乎。并且当他感到 ,他甚至不知道:有好的吃饭的地方。关键的地方在于“eat”这个动词，关于吃，那肯定是感到饿了，( 3)应该填hungry, (5)这个词根据前后判断 应该是连词，i开头的连词，我们初中就学到的一个，那就是 if,犹未注意这里的if是表示是否的 意思。后半句语意完整了，那我们就通过揣测后半句来推前半句， 后半句的句意为并且当他感到饥 饿的时候，他设置不知道是否有好的吃饭的地方。用 and并列两个相同的情况，除了饥饿之外，那就是迷路了，所以要用到词组 b

10、e lost, (3)处应该填lost(6) Now he is studying English b_(6)_ listening to tapes.(6)前后的关系,我们知道现在他正在 学习英语通过听磁带的方式。 By the way, are you free tonight? How about having dinner and then see the latest 3D m_?在最流行的就是3D电影了，所以出现了 3D,那后面又是以m字母开头，显然应该填 movie,此 处应该用单数，因为前面有最高级例 2： Read the passage and fill in the bl

11、anks with proper words：在短文的空格内填入适当的词，使其内容通顺。每空格限填一词，首字母已给)Dreams may be more important than sleep. Some people don't need much sleep. H_(1)_, we all need to dream according to the scientists.Dreams take up about one quarter of our sleeping time. People have several dreams e_(2)_ night. Dreams ar

12、e like short films. They are usually in color. Some dreams are l_(3)_ old films. They come to us over and again. That may be because the dreamer is worrying about something.Dreaming may be a w_(4)_ of trying to find an answer. Some people get new ideas about their work from dreams. They could have b

14、am. Our mind is hard at workwhen we dream. That is why we may have a long sleep and still wake up tired.1.2.3.4.5.6.7.Key: 1. However 2. every 3. like 4. way 5. thinking 6. disappear 7. more首字母填空小技巧：判断词性与句子成分(1)通过这个空格，大家很容易判断在逗号前常出现的就是转折副词However然而，我们在将结合上下旬意思进行检验，一些人不需要太多的睡眠。然而，根据科学家所说，我们都需要做梦。 前后句

15、子的关系是转折关系。(2)从句子成分而言，e night在句子中做时间状语，从词性来讲，night是跟名词，前应用形容词来修饰，所以此处应该填的是 every(3) Some dreams are l_ 01d films句子成分中，此处要不做的是状语，要不做的就是 表语，若做表语(3)处填的就应该是一个形容词或者名词，但是从整句句意来看，(3)应该填的是介词，在整句句子中作状语，表示的意思为一些梦就像是老电影(4) a冠词后面往往跟的是名词短语，而在(4)有介词of,所以(4)填的是一个名词，结 合整句句子来看，做梦也许是尝试找到一个答案的方法(5) have been t ,这个结构中很容

16、易看出是一个时态的结构，在be动词后如果跟现在分词表示进行，如果be动词后跟过去分词，则表示被动，从此处来看不存在被动关系，所以此处应该用现在分词thinking ,整句话的意思为他们却不能一整天在谈论他们的工作(6) Dreams can d_(6)_ quickly from memory.在can情态动词之后应该跟动词原形， 所以(6) 应该填的是一个动词，从整句话中可以看出，梦能够从记忆中快速消失，所以用 disappear(7) The m_(7)_ we sleep, the longer we dream此句中用了一个 the+比较级，the+比较级的 结构，从后一句来看long

17、er是副词的比较级，所以前者应该也用副词的比较级，整句句意表示为我们睡的越多，我们做梦的时间就越长，所以此处填 more例 3: Read the passage and fill in the blanks with proper words:(在短文的空格内填入适当的词， 使其内容通顺。每空格限填一词，首字母已给)Should children stop playing computer games or not? That's always a hot topic.- 厂I _Computer games may h_(1)_ you learn how to use compu

20、use a computer for more than 30 minutes w_(7)_ a rest.1.2.3.4.5.6.7.Key: 1. help 2. fun 3. also 4. what 5. enjoy 6. hurt 7. without首字母填空小技巧：(1) may后应该跟的是动词原形，通过整句话的意思应填help,而在初中要学到一个词组help sb (to) do sth,从而验证此处应填help(2)根据比较连词than,这里应该填的是一个形容词的比较级(be+形容词)，而前面有more这 个形容词的比较级，后面应该填一个名词，比起去上电脑课他们更有趣些。所以

21、此处填名词fun(3)通过句意与词性判断，这里应该填一个副词，而整句句子意思为游戏也能使你的脑子快速地 工作(4)疑问词+不定式的结构，因为do后应跟的是宾语，所以应该用 what to do,句意是你不得不 在很短的时间内找出做什么(5)词组enjoy oneself,通过and这个表示并列的连词，而后面 relax表示and前面也应该有表示 娱乐的意义在里面(6)词组get hurt, if这个连词引导的是条件性状语从句，如果你在电脑前坐很长的时间，你的手、背和眼睛会受到伤害，所以此处填 hurt（7）从句意进行判断：孩子们不应该用电脑超过30分钟没有休息的情况下，这里应该填without

22、这个介词，表示在没有例4:Here's a story about Ming's life on the waters. Ming has lived all his life on a wide r 1 in China. His home is a large house-boat with a roof, one of hundreds that move up and down. In about six years he has not once been on l 2 but he is never lonely. He is a strong swimmer. I

23、n fact, he could swim before he could walk. When he wants to play with his f 3 he just swims across to their boats or asks them to v 4 him.Ming' s father is a fisherman, but he never u5 a line or a net （网）.Great black birds called cormorants do the fishing for him. Rings （圈）have been put around

24、the birds n 6 so that they cannot eat the fish they catch. They have been t 7 to bring the fish to people. And then people I 1reward （奖励）them with a fine big fish as soon as their work is f 8 Ming loves watching thecormorants, but better still he likes going s 9 with his mother. The shops, of course

25、, are boats verylike his o 10.1. river 2. land 3. friends 4.visit 5. uses 6. necks 7. taught/trained 8. finished 9. shopping 10. own【解析】本篇短文第一句“关于明的在水上的生活”，给大家一个总体的信息，重点是“on the waters , 而且时态为现在时。1 .既然Ming的生活是和水紧密联系的，所以第一个空就很容易了，r打头的关于水的单词，就是river,因为前面有冠词a,所以只用单数形式。2 .通过前文可以得知，“Ming住在一个船型的屋子里，6年里他从来

26、没有到过*，但是他从来不孤 单”，也就是说他非常喜欢在水上的生活，因此可以推测出他从来没有来过陆地，填 lando3 .本空的关键在play with ,通常后面可以加fire、snow,但是与文意不符，所以是与朋友们玩，后 文的their说明是复数形式，填friends。4 .本空的ask them to * him和or之前的swims across to their boats!相互对应的，要么 Ming去朋 友那里，要么他的朋友来看他，所以填 visit,表示拜访的意思。5 .本句说到，Ming的父亲是一位渔夫，一位渔夫捕鱼用线或者网是非常正常的事情，但but表示转折，说明他的父亲与一

27、般渔夫不一样，不使用线或者网，后文的 birds do the fishing for him也说明 他自己不需要用这些工具。他的父亲是第三人称，所以填 uses6 .本题是难题，通过上下文可以得知，Ming的父亲在那些的鹦的某个部位圈上了圈，所以它们就不能把捕到的鱼吃下去了。通常的鹦吃鱼是直接吞的，如果不让它们吃下去的话只能在脖子上圈住， 这样鱼就会卡住，吞不下去，而且的鹦是复数形式，所以填neckso7 .那些的鹦不是天生就会为 Ming的父亲捕鱼的，而是通过后天的训练和教导，所以填taught或者trainedo8 .通过句意得知，当的鹦的工作*了之后，它们会得到一大条鱼作为奖励，从逻辑

28、上来看，应该是 完成工作后，而且空前有is,所以填finished。9 .最后一句中，出现了 shop,提示了此空和shop有关，应该是由go引导固定词组，go shopping, 表示去购物。10 .本题也是难题。因为Ming是生活在水上的，那么肯定商店也是在水上的，从短文的第二句可以推测出，商店也是和 Ming的家的外形很像，所以填own,词组of one's own表示某人的，这里解 释为“这个商店也和Ming自己的家外形很像”。例 5: Can animals be made to work for people? Some scientiststhink that one d

29、ay animals may be trained to do a number of simple jobs i 1 ofpeople. They say that at a circu s（杂技场），forexample, we may see elephants, monkeys, dogs and other animals doing q2 skillful （熟练的）things. Perhaps you have seen them onthe television or in a film. If you watch closely, you may find that the

The scientistssay that many d 5 animals may be trained to do a lot of simple things if they know theywill get a reward f 6 doing that./ Jil 111 I I j I I ,Of course,as we know, dogs can be trained to look after a house, and s

31、oldiers in both oldand modern 7 have u 8 geeseto give warning（警报）by m9 a lot of noise when an enemy comes near. And also it may be possible totrain animals to work in families or f 101. instead 2. quite 3. gives 4.or 5. different 6. for 7. times 8. used 9. making 10.factories【解析】本篇短文的首句，用一个疑问句来提出了 “

32、动物可以为人类工作？”，说明本篇文章将围 绕此问题展开，而且时态为现在时。 ,I, ,1 .通过本句句意理解，“科学家认为有一大动物可以被训练，然后做一些简单的工作”，意思与文 章首句呼应，所以是代替人们做简单的工作，填insteadof,表示代替。2 .本空可以使用语法上的技巧。如果本空忽略不看的话，句子仍然是成立的，说明填的单词词形不 会是名词、动词或形容词，所以只能填副词来修饰skillful ,那么“非常”可以用quite来表示，因此填quite。 i3 .本空应该填动词，当动物做好表演时，训练者会给动物一些奖励，所以填gives。4 .本题很好理解，要么给动物一些糖，要么就给水果，填

33、 or,表示选择性。5 .通过上文可以得知，现在大象、猴子、狗和其他动物都被训练做了许多事情，所以动物的种类是 多种多样的，空格前的 many也提示了不同种类的，所以填 different 06 .本题很好理解，作为的奖励，用介词for。7 .本题考察的是词组的运用，表示在以前和现在，填 times,表示时代。8.在以前和现在，士兵们都用鹅来发警报，使用某物，填use,前面有have表示现在完成时，因此填 used9 .本题考察的是词组的固定搭配，通过让鹅制造噪音来提醒士兵们有敌人靠近了，词组是makenoise,前面有介词 by,所以填 making。10 .本题的逻辑词是or,表示选择性，

34、说明本空也是一个表示地点的词，并且同样是由介词in引导,所以不能填farm （onthe farm§而且应该和families呼应，要用复数形式，填factories。例 6: In recent years, playing kite-board seems tobecome more and more popular in Alaska in America. It is a new and old game.The game has w 1 theinterest of many young people. The game is interesting but a littl

35、e d 2.One needs to play it very c 3A kite-board is in fact a skateboard （滑雪板） drawn （拉）by a few big flying kites.

It is not s 9 .It is said that the game can exercise not only your b 10 but also the sensitivity of your brain 大脑的敏 捷

37、）. 一、1 一»« I. *u"1. won 2.difficult/dangerous3. carefully 4. played5.early6.few7.learn8. fast 9. safe 10. body【解析】通过本文第一句，可以得知文章的中心主体是kite-board （风筝板，冲浪运动的一种，可以借助风力飞上大）。1 .通过文章首句，可以得知近些年风筝板越来越流行，既然如此流行，必定会让年轻人产生浓厚 的兴趣，空1所在的句子白兴趣用了 interest名词形式，说明要用一个动词来表示出“引起、得到” 的意思，那么很容易想到“赢得某人的兴趣”，

38、用win,前面有has是现在完成时，所以win改成won。2 .空2的关键点在于逻辑词but, but表示前后意思的转折，“风筝板很有趣，但是也很那么和“有趣”相对的就是“危险”或者“困难”，所以dangerous或difficult皆可。3 .第一段最后一句是前面一句的延伸，如果空2填出来，空3就不成问题，正是因为这项运动很危险，所以玩的时候必须要非常小心仔细，填 carefully o4 .文章首句就有playing kite-board,提示出空4应该是play的被动语态，填played。5 .本题考察的是as-as的结构，当中填形容词或者副词的原级，关键点在结构后的last centu

39、ry,既然已经是上个世纪，不难想出应该是“和上世纪一样早"，所以填 early。6 .本局先有Since引导出了一个原因，“因为风筝板非常难以控制”，而导致“结果就是很少有人 敢玩"，所以填few。learn。7.本题难度不大，是“许多人们可以学习如何去玩”，所以填8.本题的关键在于空格后的50 kilometers an hour (每小时50公里)，不难得知这是一个速度，所 以是和这速度一样快，所以填fast。9 .本题是逻辑题，通过前半句可以得知“如果没有练习，最好不要玩”，后半句就是解释为什么 不要去玩，因为不是很安全，所以填 safe10 .通过整篇文章，我们对风

40、筝板的运动有了一个大概的了解，它可以让人们得到锻炼，所以是锻 炼身体，因此填body。例 7: Read the passage and fill in the blanks with proper words：在短文的空格内填入适当的词，使其内容通顺。每空格限填一词，首字母已给), , r 1 I We call the Chinese New Year the Spring Festival. There is a n_(1)_ for each Chinese year - the year of the sheep, the year of the monkey, the year o

43、句中，而(1)题中，破折号起解释说明的作用, 是解题的关键， " the year of the sheep, the year of the monkey, the year of the tiger, etc这部分明显是对a+名词，其中名词的解释，根据这点，判断应填name(2)还是用“近”的方法，关键在于此句中cleaning, are doing,这个词组我们就立刻可以想至U be busy doing的结构(3) to是表示目的，目的是为了迎新，故就填 welcome (wait这个词后面是要跟for的哦，所以此 处不能用wait)(4)、(5)在这句话中同时出现了两个空格

44、，这时就需要纵观全句进行首字母填空，从最完整的先看and go visit their relatives and friends去拜访他们的亲戚和朋友，and与前半部分有着承接的关 系，put on这个词组表示穿上，穿上的必然是衣服，所以填 clothes (注意不能填cloth,要用复数) 再通过已填的空与the我们可以得出应该是在新年的第一大，所以应用 first(6) “Happy New Year”与greetings属于同类，都是表示问好，所以用 and连接usually(7)从整句句子来看，在行为动词前应该常用副词修饰，通过全句的解释，应用例 8: Read the passag

51、说明之前有人说她是失败的明星，前句表示许多人说她的成功只是好运(与后一 句推测的意思相吻合)，所以此处应该填luck,因为good是形容词后应该填的是名词(2) During the past month, she has won gold medals and b_(2)_ the world record three times in this event在过去的几个月，她已经赢得了多枚金牌，这里的并列连词and表示前后应该是并列的关系， 后面我们也可以想到一个词组 break the record打破记录，由此应该填break,但要注意时态的变化， 这里与前面的won共用一个has,所以

52、应该填过去分词broken(3) The 20-year-old girl says she hasn't had a day off s_(3)_ she won the silver medal at Rome World Championships in July, 2009这题我们可以通过语法点来解题，前句用的现在完成时态，后句用的一般过去时态，那连接这一时态的连词在我们初中学习的s开头的只有since(4) When she's not training, Liu keeps herself away from the noisy world outside. Tha
