　　6．By saying “We need them yesterday” (paragraph 7)，Stover means that snakelike robots . 二、詞義猜測(cè)主要的解題策略有：語(yǔ)境猜詞、語(yǔ)法猜詞和常識(shí)猜詞。語(yǔ)境即上下文。由于上下文中的生詞不是孤立存在的，其詞義與句中其他詞的詞義或具體的語(yǔ)境有著密切的聯(lián)系。因此在閱讀過(guò)程中，許多生詞的詞義可以充分利用上下文中相關(guān)的詞匯和短語(yǔ)并結(jié)合具體的語(yǔ)境來(lái)推測(cè)。命題者為了考查學(xué)生的這種猜詞能力，常采用以下幾種命題策略：閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 策略1：依據(jù)標(biāo)點(diǎn)符號(hào)猜測(cè)詞義標(biāo)點(diǎn)符號(hào)是詞義猜測(cè)的最直接，最簡(jiǎn)單的解答方法。比如，破折號(hào)、冒號(hào)常常起解釋說(shuō)明的功能，引號(hào)和括號(hào)有時(shí)也起到相同的作用。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 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 閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 【點(diǎn)睛】 D　破折號(hào)起進(jìn)一步解釋說(shuō)明的作用。由句前信息 “他為逃避妻子的嘮叨而逃到屋外”可知“他是一個(gè)怕老婆的人”，因此選擇D項(xiàng)。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 策略2：依據(jù)反義詞和對(duì)比關(guān)系猜測(cè)詞義運(yùn)用對(duì)比手法描述事物或現(xiàn)象是文章寫(xiě)作的一種常用的修辭手法。在這種修辭手段下，作者常借用一些信號(hào)詞來(lái)提供相反信息，從而表明一個(gè)詞與前面的另一個(gè)詞互為反義。常用的信號(hào)詞有： 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。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 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. 【點(diǎn)睛】 D　由but引導(dǎo)的前后句可知，exotic與quite normal(相當(dāng)平常)在意義上是互為反義的，因此選擇D項(xiàng)foreign and unusual(異乎尋常)。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 策略3：依據(jù)下定義，作解釋猜測(cè)詞義在說(shuō)明文、科技文中運(yùn)用下定義或解釋概念的方法來(lái)定義或詮釋某一名詞或概念是文章寫(xiě)作的又一特點(diǎn)。在寫(xiě)作方法上常采用先總后分(即先定義后解釋)或先分后總(即先說(shuō)明后結(jié)論)的方式。常用的定義信號(hào)詞有：be defined as/be termed(被定義為)，be called(被稱(chēng)為)，mean/refer to/be(意指，是)。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 例3　[2011·安徽卷] (節(jié)選) 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.” 閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 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. 【點(diǎn)睛】 A　詞義猜測(cè)題。本題是根據(jù)結(jié)構(gòu)上的“總—分”關(guān)系猜測(cè)詞義。文章首句先表明觀點(diǎn)，然后進(jìn)一步清楚地分述自己的觀點(diǎn)——沒(méi)有噪音，我們會(huì)專(zhuān)注生活中各種美好的聲音。再結(jié)合上下文可以看出George Prochnik是反對(duì)噪音的，所以他應(yīng)該是喜歡安靜的，故答案選A。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 策略4：依據(jù)邏輯推理猜測(cè)詞義運(yùn)用邏輯推理猜測(cè)詞義是使用最廣考查最多也是最易失分的猜詞方式。要求考生具備整合分散、復(fù)雜信息的能力，充分利用上下文中相關(guān)的詞匯并結(jié)合具體的語(yǔ)境，從形式和內(nèi)容上把握語(yǔ)言之間的內(nèi)在聯(lián)系，理順語(yǔ)言之間的邏輯關(guān)系，進(jìn)而達(dá)到猜詞的目的。常見(jiàn)的邏輯關(guān)系有：因果關(guān)系、同位關(guān)系、對(duì)比關(guān)系，轉(zhuǎn)折關(guān)系等。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 例4 　[2011·四川卷] (節(jié)選) 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. 閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 【點(diǎn)睛】 B　詞義猜測(cè)題。本題是根據(jù)解說(shuō)關(guān)系猜測(cè)詞義。從文中“A commitment to change my life with a way that reduces daily anxiety，…above all improves my body shape.”可知，“減少焦慮、增強(qiáng)信心…改變體型”即不定式部分是修飾commitment的，結(jié)合文意可推斷出commitment意為“堅(jiān)強(qiáng)的信念”，故選擇B項(xiàng)。本題容易受字面意思的影響而誤選C項(xiàng)。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 策略5：依據(jù)替代詞猜測(cè)詞義使用替代詞 it, they, them, one(s), these, that 或 the other (two…)等指代上下文中詞匯或句義是猜測(cè)詞義的另一種形式。

　　閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 策略6：依據(jù)例證猜測(cè)詞義采用事實(shí)說(shuō)理(即例證)以加強(qiáng)觀點(diǎn)的說(shuō)服力或使觀點(diǎn)更加明朗清楚是文章寫(xiě)作的常用手法。借助例證獲取更多信息，即可實(shí)現(xiàn)猜詞的目的。常用的例證信號(hào)詞有： like/for example/for instance/such as; include/consist of 等。此外，運(yùn)用語(yǔ)法和常識(shí)以達(dá)到猜詞的目的也是詞義猜測(cè)策略的另一種表現(xiàn)形式。英語(yǔ)構(gòu)詞法給英語(yǔ)語(yǔ)言創(chuàng)造了豐富的詞匯源泉，因此掌握構(gòu)詞規(guī)律是達(dá)到猜詞目的的有效捷徑。這種猜詞的策略主要表現(xiàn)在：閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) (1)依據(jù)詞性變化猜測(cè)詞義英語(yǔ)語(yǔ)言的詞性變化是非常活躍的，如名詞動(dòng)化、動(dòng)詞名化、形容詞動(dòng)化等，閱讀時(shí)要充分抓住這一特點(diǎn)，從而準(zhǔn)確地猜測(cè)詞義。 (2)依據(jù)詞義變化(詞義引申)猜測(cè)詞義英語(yǔ)語(yǔ)言除了詞性活躍的特點(diǎn)外，其詞義的變化也是非常活躍的。同一個(gè)詞在不同的語(yǔ)境中其詞義也會(huì)發(fā)生相應(yīng)的變化，即所謂的詞義引申。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) (3)依據(jù)詞的派生和合成猜測(cè)詞義派生法是英語(yǔ)構(gòu)詞法中最主要的構(gòu)詞方法，它由詞根、前綴或后綴組成。如：前綴dis－， im－， ir－， un－可以構(gòu)成反義詞；后綴－less也以構(gòu)成反義詞。遇到合成詞時(shí)在正確理解兩詞的基礎(chǔ)上結(jié)合原文來(lái)把握兩詞之間的關(guān)系，從而準(zhǔn)確地猜測(cè)詞義。閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 【活學(xué)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

A．hardly noticeable B．heavy－h(huán)anded C．not capable of fast or immediate action D．a(chǎn) matter of habit

　　[答案] A 閱讀寫(xiě)作(二十一) │ 重視詞義猜測(cè) 3．Mrs. Morgan's son was intelligent and charming, but his continual extravagance made her wonder if she could continue to support him.
