2017—2021 年高考英语阅读理解题考查的题目基本上分为四大类:事实细节题、推理判断题、主旨大意题和词义猜测题。2017—2021 年新高考Ⅰ卷和全国卷Ⅰ的答案A、B、C、D 的分布是:4344、3444、4434、3543、4443,其规律几乎难以捉摸。那么,其命题有没有一定的规律可循呢?或者说有没有更好的解题方法和技巧呢?答案是肯定的。根据研究笔者发现,无论是全国卷还是新高考卷,高考英语阅读理解题的命制都是有一定的规律的,其四个选项主要是根据两种原则来进行命制的,即:同形项原则和二维(范畴)干扰原则。经统计发现,绝大多数的高考英语阅读理解题的选项是根据二维(范畴)干扰的原则进行命制的,如果考生能够掌握二维(范畴)干扰原则的命题规律,将大大地降低解题的难度。

一、概念解释

何谓范畴?所谓范畴,其实就是我们平时所说的类别。为了弄清楚什么叫范畴,请先看以下的例子。请问以下例子中共有几个范畴?

例1:A.Apple. B.Banana.

C.Pear. D.Watermelon.

(1 个范畴,同属于水果范畴。)

例2:A.Leaf. B.Eat.

C.108℃. D.Yummy.

(4 个范畴,属于4 个不同的范畴。)

试想一下,假如每一道高考英语阅读理解题中的4 个选项都像上面例2 一样设置4 个不同的范畴来进行考查,其难度可想而知。在教育部新颁发的《通知》中指出:高考试题选择题的题干应围绕一个中心,和选项的关系一致,干扰项的有效性和迷惑性能反映考生的典型错误,各选项的结构和语言长度应大体一致,各题正确选项的分布要基本均匀。因此,为了降低试题的难度,命题者在命题时常常会根据不同的范畴来进行命题,而这个范畴通常的组合比例为2:2 或者1:3/3:1。这就是本文接下来要讨论的“二维(范畴)干扰”的命题原则。

范畴又可以分为语言“意义”和语言“功能”。何谓语言“意义”和语言“功能”?语言“意义”指的是成对词语、成三词语、或句子所表达的意义,如:近义词、情景意义、正反意义、主次意义、抽象意义、类属意义、实虚意义和概括意义。语言“功能”指的是成对词语或成三词语和句子所用的词类、句型句式、所作句子成分和逻辑关系等。

例1:请说出以下四个选项中哪一个属于不同范畴及其范畴是什么。

A.Black. B.Red.

C.Hot. D.White.

[注:A、B、D 选项属于同一个范畴,C 选项属于不同的范畴,属于“语言意义范畴”,命题者通过两个范畴进行选项设计,这就是我们所说的二维(范畴)干扰。]

例2:请说出以下四个选项中哪一个属于不同范畴及其范畴是什么。

A.He is warm-hearted. B.He speaks loudly.

C.He is generous. D.He is polite.

[注:A、C、D 选项属于同一个范畴,B 选项属于不同的范畴,属于“语言功能范畴”,命题者通过两个范畴进行选项设计,这就是我们所说的二维(范畴)干扰。]

二、真题演绎

高考英语阅读理解题的二维(范畴)干扰命题原则分为两种形式:

1.范畴划分上分为:语言意义、形式和结构、语气、时态和语态等。

2.组合比例上分为:2:2,1:3 或者3:1(这个1 往往可能就是正确答案)。

下面笔者以2017—2021 年高考英语阅读理解题为例,具体阐述如何巧妙借助二维(范畴)干扰/结构范畴命题原则来推导试题的答案。具体操作步骤是:首先通过范畴概念排除选项(降低难度),然后通过原文信息验证答案(定位、定段、定答案)。

(1)通过“语言结构”的范畴进行命题,命题的二维干扰组合比例是2:2。

Paul Beer,head of rhino section at Port Lympne,said:“Obviously we’re all absolutely delighted to welcome another calf to our black rhino family.She’s healthy,strong and already eager to play and explore.Her mother,Solio,is a first-time mum and she is doing a fantastic job.It’s still a little too cold for them to go out into the open,but as soon as the weather warms up,I have no doubt that the little one will be out and about exploring and playing every day.”

5.What does Paul Beer say about the new-born rhino?

A.She loves staying with her mother.

B.She dislikes outdoor activities.

C.She is in good condition.

D.She is sensitive to heat.

该题为推理判断题,答案为C。

第一步:分析范畴。该题是通过“语言结构”的范畴进行命题的,二维干扰组合比例为2:2(A、B 属于动宾结构;C、D 属于系表结构),答案在A、B 或者C、D 两组之间产生。

第二步:定位、定段、定答案。读题干,可以确定关键词为“Paul Beer say”,定位到本段中Paul Beer 说的话。根据“Obviously we’re all absolutely delighted to welcome another calf to our black rhino family.She’s healthy,strong and already eager to play and explore.”可知,我们都非常高兴地欢迎另一头小牛来到我们的黑犀牛家庭。她健康、强壮,并且已经渴望玩耍和探索。由此可推断出这个新生的小犀牛状况很好。故选C 项。

(2)通过“语言形式和结构”的范畴进行命题,命题的二维干扰组合比例是1:3 或者3:1。

It doesn’t take a genius to know the answer:absolutely not.

13.What can we infer about girls from the study in Science?

A.They think themselves smart.

B.They look up to great thinkers.

C.They see gender differences earlier than boys.

D.They are likely to be influenced by social beliefs.

该题为推理判断题,答案为D。

第二步:定位、定段、定答案。读题干,可确定关键词为“girls from the study in Science”,定位到本段的“Even worse,the study found that girls act on that belief:Around age six they start to avoid activities said to be for children who are‘really,really smart’.”可知,女孩有可能被社会信念所影响。故选D 项。

【真题链接】(2019 年全国卷Ⅲ,阅读理解B)

“China is impossible to overlook,”says Hill.“Chinese models are the faces of beauty and fashion campaigns that sell dreams to women all over the world,which means Chinese women are not just consumers of fashion—they are central to its movement.”Of course,not only are today’s top Western designers being influenced by China—some of the best designers of contemporary fashion are themselves Chinese.“Vera Wang,Alexander Wang,Jason Wu are taking on Galliano,Albaz,Marc Jacobs — and beating them hands down in design and sales,”adds Hill.

25.What does Hill say about Chinese women?

A.They are setting the fashion.

B.They start many fashion campaigns.

第二步:定位、定段、定答案。读题干,可确定关键词为“Hill say”和“Chinese women”,定位到本段的“Chinese models are the faces of beauty and fashion campaigns that sell dreams to women all over the world,which means Chinese women are not just consumers of fashion—they are central to its movement.”可知,中国女性不仅是时尚的消费者,她们还是时尚发展的核心。故选A 项。

三、归纳总结

由于篇幅有限,未能一一列举例子。高考发展到今天,各个学科都逐渐形成了一些比较成熟的命题方式。出于稳定发展的考虑,高考试卷在命题方式上仍然会保持以往的传统风格。近年来,高考英语试题的难度保持在0.65 左右,整卷150 分,按照命题原则,命题人要将平均分控制在90~100 分。高考英语阅读理解题虽说有A、B、C、D四个选项,根据不完全统计,高考英语阅读理解题中的答案选项绝大多数都是根据二维(范畴)干扰原则来进行命制的,即只从两个范畴来设计选项,以降低难度。其范畴组合通常为2:2 或3:1(这个1 常常就是答案,但是仍然需要从原文获取信息来加以推导和验证),通常情况下,解题方法是:先通过范畴概念排除选项(降低难度),再通过原文信息验证答案。如果能够熟练地掌握高考英语阅读理解题的二维(范畴)干扰的命题原则,不但有助于考生降低解题难度,排除一些错误选项,从而快速地推导出正确答案,而且有助于教师明确高考英语命题规律和把握高考英语命题方向,为原创命题提供重要的参考。
