2023年高考英语全国复习考点 27-阅读理解细节理解题（重难题型解析版）

考点27阅读理解细节理解题(重难题型)

在历年高考阅读理解中，对细节理解类题型的考查同往年一样，依然占了较大的比例，全国及各省、

市均有对此题型的考查，无一例外。

细节理解题要求考生对阅读材料中的某一具体事实和细节进行理解。它们大都是根据文章中的具体信

息如事实、例证、原因、过程、论述等进行提问的。有些问题可以在文章中直接找到答案，有些则需要我

们在理解的基础上将有关内容系统化才能找到，比如计算、排序、是非判断、图形比较等。

常见的命题方式通常有：

1.特殊疑问句形式。以when,where,what,which,who,howmuch/many等疑问词开头引出的问题；

2.以是非题的形式。true/false,nottrue/false或EXCEPT,近年这种题型较少；

3.以Accordingto…开头提问方式；

4.以填空题的形式，如：

(1)Toavoidattractingmountainlions,peopleareadvised.

(2)ByIhefirstsentenceofthepassageauthormeansthat.

(3)Itseemsthatnowacountry'seconomydependsmuchon.

(4)Ifyouareinterestedinknowingaboutwhatpeople'slifewillbe,youmayvisit.

(5)Thepolicemenweretold“tolooktheotherway”(theunderlinedpartinParagraph2)sothat.

(6)Thepolicemanwhosaid“Goodevening"toRollswantedto.

5.就文中数字、排序、识图等提问。

做细节理解题时，大多数学生易出现的问题是阅读速度太慢，缺乏一定的快速阅读技巧，考生要培养

自己快速获取信息的能力。解答此类试题时，不必通篇细看原文，而常常可采取“带着问题找答案''的方

法.先从问题中抓住关键性词语。然后以此为线索。要快速地辨认和记忆事实或细节，就要恰当地运用略

读及查读的技巧快速在文章中寻找与此问题相关的段落、语句.仔细品味，对照比较.确定答案。除了运

用扫读法(scanning)外，还可以兼用排除法.将“无此细节”和“与此细节相反”的选项排除。

了解细节题干扰选项的特点也有助于考生提高答题的正确率。一般情况下，干扰项有如下几个特点：

(1)是原文信息，但不是题目要求的内容；(2)符合常识，但不是文章内容；(3)与原文的内容极其

相似，只是在程度上有些变动；(4)在意思上与原文大相径庭甚至完全相反；(5)部分正确，部分错误。

有的细节理解题只要直接辨认不要求读者对客观的事实作出解释或判断，只要求从阅读材料中直接获

取信息。同时还要求读者记住重要细节，在必要的时候(做判断、推断或结论的时候)能够准确而迅速地

将他们回忆起来。解此类题要求考生快速抓住原文中的关键信息，直接得出答案，但要注意往往答案与原

文中的语句并非一模一样，而是用不同的词语或句型结构表达相同的意思。有的细节理解题就需要通过有

关词语和句子的转换。利用主要事实、图表、图形来获取信息，然后利用因果、类比、时间、空间等关系

将零碎的细节经过一系列加工、整理，方能做出正确的判断.此类试题在高考中占大多数。

值得一提的是，有时原文中的信息可能只是一个短语，甚至一个单词，因此需要我们在阅读中特别仔

细才能捕捉到真正有用的信息。

细节理解题大致有如下几种常考题型：

题型一描写类细节题

描写类细节题，常常考查考生对文中有关人物动作、思想感情、心理活动、观点，或事件的起因、发

展、过程、结果等方面的理解。这类描写信息往往较直接，一般不太需要考生对它们进行较深入的理解,

对于该类题，考生一般都可以较直接地从原文中找到与题目对应的有关信息。

centimeterofair,itisdubbedasanaturaloxygenbarand“themostbeautifulhealthcare-themedvalley."（空气中

celebrated."（体验当地苗族民俗文化是一个不错的主意，特别是当你选择在5月的传统苗族踩山会的时候

去参观。）可知，前往黑山谷的最佳旅游时间是五月。故选C项。

题型二信息寻找题、广告阅读题

信息寻找题一般在应用文体中较常见，体现于查字典、阅读广告、公告、演出海报、车船航班时间表

等之中。这类阅读材料包含的某一方面的信息非常全面，能满足各种人对信息的需求，但在高考试题中，

常常是就某一方面提问，考生完全没有必要从头到尾仔细阅读，因为材料中有很多冗余无效信息。做此类

题时，宜采用“题干定全法即：先阅读题干，然后根据问题要求，有针对性地阅读相关部分快速寻找有

效信息。

广告是阅读理解题常考的一种题材。广告属应用文体。严格来说广告属快速寻找信息题。但是广告有

着其他快速寻找信息题不同的特点。广告文体简洁明快，省略了大量的词语，达到了篇幅小、信息多的目

的。同时具有语言精练，形象性、鼓动性强的良好效果。广告阅读题多为细节理解题，关键在于正确理解

广告内容。考生必须具备较强的语言运用能力，熟悉文化背景，利用各种手段（如：补全、联想、推测等）

正确解读广告的内容。通常运用“补全成分法”和“联想推测法”两种方法来解读广告的内容。做题方法同样

采用“题干定向法”。

（1）补全成分法

省略名在广告体阅读材料中大量出现，可以说广告阅读理解材料中大多数句子都是省略句。我们应结

合全文语境及逻辑关系将省略句补全，从而更加准确地理解。如：Driverwanted.根据文义，可将该句补

充为：Adriverwillbewanted.（招聘一名司机）。

（2）联想推测法

在些广告时间、日期、地点、电话、票价等用了缩略词，甚至一概没有提及，这就需要考生前后连贯，

充分想象，整体理解。搜寻已知信息，推断语篇意义。

为节省篇幅，特别是在商业广告中，常使用缩写词，尽管有些缩写不太规范，但却常用，常见的缩写

词有：

Tel.=telephonenumber

Ph.=phoneAdd(r).=address

co.=companyLtd=Limited

Max=maximumMin=minimum

hr=hourt=time

fig=figureft=fbot

ml=miledoz=dozen

题型三数据计算题

此类试题一般要求考生能根据阅读材料中给出的有关数据，找出计算关系，通过计算，得出正确的结

论。这类计算•般来说比较简单，关键是要弄清各数据间的逻辑关系，选准比较的数据，弄清单位换算关

系，确定计算方法，问题便迎刃而解了。对于数据较多、项目复杂用时间或空间跨度较大的短文，通常可

采用“列表法”，即按一定的规律将数据分门别类地列出，化模糊为清晰，为计算打下基础。对于相对不太

复杂的数据，可采用“推算法”，即以有关数据为基准，进行简单的运算就可得出。

均每年有（4.5million-28,260）4-39=114660）只帝王蝶消失。故选C项。

题型四排序题

这种试题要求考生根据事情发生的先后顺序和句子之间的逻辑关系，找出事件的正确顺序。

做此类题目可采用“首尾定位法”，即先找出第一个事件和最后一个事件，这样可以迅速缩小选择范

围，从而迅速找到答案。阅读理解的文章如果是记叙文，排序题通常以事件发生的时间为线索；如果是说

明文，排序题通常以说明的先后顺序为线索；如果是议论文，排序题通常以逻辑顺序为线索。从近几年高

考试题来看，这类试题主要出现在记叙文和说明文中。

6.代词指代题解题技能

代词指代题要求考生一定的上下文推测代词的指代意义。此类题一般是在人物或事物关系比较复杂的

情况下使用的一种题型，所以理清人物及事物之间的逻辑关系是关键所在。
