  6.By saying “We need them yesterday” (paragraph 7),Stover means that snakelike robots . 二、词义猜测主要的解题策略有:语境猜词、语法猜词和常识猜词。 语境即上下文。由于上下文中的生词不是孤立存在的,其词义与句中其他词的词义或具体的语境有着密切的联系。因此在阅读过程中,许多生词的词义可以充分利用上下文中相关的词汇和短语并结合具体的语境来推测。命题者为了考查学生的这种猜词能力,常采用以下几种命题策略: 阅读写作(二十一) │ 重视词义猜测 策略1:依据标点符号猜测词义 标点符号是词义猜测的最直接,最简单的解答方法。比如,破折号、冒号常常起解释说明的功能,引号和括号有时也起到相同的作用。 阅读写作(二十一) │ 重视词义猜测 例1 Morning, noon, and night, her tongue was endlessly going, so that he was forced to escape to the outside of the house—the only side which, in truth, belongs to a henpecked husband. The underlined words “henpecked husband” in the last paragraph probably means a man who . A.likes hunting

  B.is afraid of hens C.loves his wife

  D.is afraid of his wife 阅读写作(二十一) │ 重视词义猜测 【点睛】 D 破折号起进一步解释说明的作用。由句前信息 “他为逃避妻子的唠叨而逃到屋外”可知“他是一个怕老婆的人”,因此选择D项。 阅读写作(二十一) │ 重视词义猜测 策略2:依据反义词和对比关系猜测词义 运用对比手法描述事物或现象是文章写作的一种常用的修辞手法。在这种修辞手段下,作者常借用一些信号词来提供相反信息,从而表明一个词与前面的另一个词互为反义。常用的信号词有: but/yet/however/nevertheless; while/whereas; otherwise/or else; unlike/instead/ rather than; by contrast/compared to; on the contrary/ on the other hand 等。 阅读写作(二十一) │ 重视词义猜测 例2 The house looked quite normal outside, but inside it was very exotic with fascinating objects on display. Which of the definitions is closest in meaning to the word “exotic” in the passage? A.Messy and untidy.      B.Rich and expensive. C.Comfortable and calming.

  D.Foreign and unusual. 【点睛】 D 由but引导的前后句可知,exotic与quite normal(相当平常)在意义上是互为反义的,因此选择D项foreign and unusual(异乎寻常)。 阅读写作(二十一) │ 重视词义猜测 策略3:依据下定义,作解释猜测词义 在说明文、科技文中运用下定义或解释概念的方法来定义或诠释某一名词或概念是文章写作的又一特点。在写作方法上常采用先总后分(即先定义后解释)或先分后总(即先说明后结论)的方式。常用的定义信号词有:be defined as/be termed(被定义为),be called(被称为),mean/refer to/be(意指,是)。 阅读写作(二十一) │ 重视词义猜测 例3 [2011·安徽卷] (节选) George Prochnik would like the world to put a sock in it. He makes his case in a new book,Listening for Meaning in a World of Noise. Here he explains himself (using his indoor voice): “We've become so accustomed to noise,there's almost a deep prejudice against the idea that silence might be beneficial. If you tell someone to be quiet,you sound like an old man. But it's never been more important to find continuing quiet. Silence focuses us,improves our health,and is a key to lasting peace and satisfaction.” 阅读写作(二十一) │ 重视词义猜测 What does the phrase “to put a sock in it ”in Paragraph 1 probably mean? A.To be quiet. B.To be colorful. C.To be full of love.

  D.To be attentive to someone. 【点睛】 A 词义猜测题。本题是根据结构上的“总—分”关系猜测词义。文章首句先表明观点,然后进一步清楚地分述自己的观点——没有噪音,我们会专注生活中各种美好的声音。再结合上下文可以看出George Prochnik是反对噪音的,所以他应该是喜欢安静的,故答案选A。 阅读写作(二十一) │ 重视词义猜测 策略4:依据逻辑推理猜测词义 运用逻辑推理猜测词义是使用最广考查最多也是最易失分的猜词方式。要求考生具备整合分散、复杂信息的能力,充分利用上下文中相关的词汇并结合具体的语境,从形式和内容上把握语言之间的内在联系,理顺语言之间的逻辑关系,进而达到猜词的目的。常见的逻辑关系有:因果关系、同位关系、对比关系,转折关系等。 阅读写作(二十一) │ 重视词义猜测 例4  [2011·四川卷] (节选) So what drives me to roll out of bed at 5:00 a.m.?What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety,increases self-confidence and energy,extends life and above all improves my body shape. What does the underlined word “commitment” in the last paragraph mean? A.Good health.

  B.Firm belief.

  C.A strong power.

  D.A regular habit. 阅读写作(二十一) │ 重视词义猜测 【点睛】 B 词义猜测题。本题是根据解说关系猜测词义。从文中“A commitment to change my life with a way that reduces daily anxiety,…above all improves my body shape.”可知,“减少焦虑、增强信心…改变体型”即不定式部分是修饰commitment的,结合文意可推断出commitment意为“坚强的信念”,故选择B项。本题容易受字面意思的影响而误选C项。 阅读写作(二十一) │ 重视词义猜测 策略5:依据替代词猜测词义 使用替代词 it, they, them, one(s), these, that 或 the other (two…)等指代上下文中词汇或句义是猜测词义的另一种形式。

  阅读写作(二十一) │ 重视词义猜测 策略6:依据例证猜测词义 采用事实说理(即例证)以加强观点的说服力或使观点更加明朗清楚是文章写作的常用手法。借助例证获取更多信息,即可实现猜词的目的。常用的例证信号词有: like/for example/for instance/such as; include/consist of 等。 此外,运用语法和常识以达到猜词的目的也是词义猜测策略的另一种表现形式。英语构词法给英语语言创造了丰富的词汇源泉,因此掌握构词规律是达到猜词目的的有效捷径。这种猜词的策略主要表现在: 阅读写作(二十一) │ 重视词义猜测 (1)依据词性变化猜测词义 英语语言的词性变化是非常活跃的,如名词动化、动词名化、形容词动化等,阅读时要充分抓住这一特点,从而准确地猜测词义。 (2)依据词义变化(词义引申)猜测词义 英语语言除了词性活跃的特点外,其词义的变化也是非常活跃的。同一个词在不同的语境中其词义也会发生相应的变化,即所谓的词义引申。 阅读写作(二十一) │ 重视词义猜测 (3)依据词的派生和合成猜测词义 派生法是英语构词法中最主要的构词方法,它由词根、前缀或后缀组成。如:前缀dis-, im-, ir-, un-可以构成反义词;后缀-less也以构成反义词。遇到合成词时在正确理解两词的基础上结合原文来把握两词之间的关系,从而准确地猜测词义。 阅读写作(二十一) │ 重视词义猜测 【活学活用】 1.The ruler had been so cruel and dishonest that after the revolution she was banished. A few members of the Senate opposed this decision, but the majority voted that the ruler should leave the country forever. A.killed by stoning

  B.sent away C.imprisoned

  D.punished by whipping

A.hardly noticeable B.heavy-handed C.not capable of fast or immediate action D.a matter of habit
