Sorry,you cant as you havent recovered from the knee injury.,方法一根據(jù)句子成分確定關(guān)系詞 解答考查定語(yǔ)從句的試題的關(guān)鍵就是找到先行詞,然后分析從句結(jié)構(gòu),可將先行詞代入從句,看其在從句里充

59、當(dāng)什么成分。如果先行詞作從句的主語(yǔ)、賓語(yǔ)或表語(yǔ),關(guān)系詞一般要用which,that,who或whom;如果先行詞作從句的狀語(yǔ),關(guān)系詞一般要用when,where或why;如果先行詞和定語(yǔ)從句的主語(yǔ)為所屬關(guān)系,關(guān)系詞一般要用whose。當(dāng)然,還要結(jié)合定語(yǔ)從句的其他規(guī)則(如先行詞是不定代詞時(shí),用that指代事物)才能做出最后的選擇。,方法技巧,例1The president of the World Bank says he has a passion for China, started as early as his childhood. A.whereB.which C.what D.whe

60、n,解析本題的重點(diǎn)是判斷句子結(jié)構(gòu),確定從句類型。一旦確定是定語(yǔ)從句,就可以側(cè)重分析從句,判斷從句中缺少什么成分,這也是我們解決從句類考題的基本方法。根據(jù)句意和句子結(jié)構(gòu)可知,設(shè)空處引導(dǎo)非限制性定語(yǔ)從句,先行詞是passion,指物,關(guān)系詞在定語(yǔ)從句中作主語(yǔ);where和when是關(guān)系副詞,在定語(yǔ)從句中作狀語(yǔ);what不引導(dǎo)定語(yǔ)從句。因此which正確。,例2The singer confirmed her claim she had made to the media she said she would not leave the band. A.whatB.thatC.whenD.where

61、,解析根據(jù)句子結(jié)構(gòu)可知,設(shè)空處引導(dǎo)定語(yǔ)從句,先行詞為claim,而不是media,句子可還原為In her claim she said she would not leave the band。由此可見,關(guān)系詞在從句中作地點(diǎn)狀語(yǔ),應(yīng)用where引導(dǎo)定語(yǔ)從句。此處容易被誤認(rèn)為是同位語(yǔ)從句而選用that,如果從句中的she said去掉,則是同位語(yǔ)從句,補(bǔ)充說(shuō)明claim的具體內(nèi)容。,方法二根據(jù)句子結(jié)構(gòu)確定從句類型 如果確定從句是名詞性從句,就要進(jìn)一步確定它是賓語(yǔ)從句、主語(yǔ)從句、表語(yǔ)從句還是同位語(yǔ)從句,然后再仔細(xì)分析從句結(jié)構(gòu),看從句是否完整(先看結(jié)構(gòu),再看意義),最后根據(jù)“缺什么補(bǔ)什么”的原則,

62、確定恰當(dāng)?shù)倪B接詞。,例1Do not let failure discourage you,for you can never tellclose you may be to victory. A.howB.thatC.whichD.where,解析分析句子結(jié)構(gòu)可知,本題考查名詞性從句。句意:不要讓失敗使你泄氣,因?yàn)槟阌肋h(yuǎn)也不會(huì)知道你可能離成功有多近。動(dòng)詞tell后面的close you may be to victory為賓語(yǔ)從句,設(shè)空后的close為形容詞,只能用how來(lái)修飾,表示程度,故選A項(xiàng)。,例2A problem has occurred we should develop inn

63、ovative think-ing abilities in the classroom by giving students opportunities to generate new ideas. A.whatB.whereC.whetherD.that,解析分析句子結(jié)構(gòu)可知,本題考查名詞性從句。句意:我們是否應(yīng)該通過(guò)給學(xué)生創(chuàng)造新思想的機(jī)會(huì),來(lái)培養(yǎng)學(xué)生的創(chuàng)新思維能力, 這個(gè)問(wèn)題已經(jīng)出現(xiàn)了。由此可見,設(shè)空處引導(dǎo)同位語(yǔ)從句,對(duì)problem的內(nèi)容進(jìn)行具體說(shuō)明,從句不缺少成分,根據(jù)句意可知,此處表示“是否”,故用whether引導(dǎo)同位語(yǔ)從句。,方法三根據(jù)句子含義確定主、從句之間的邏輯關(guān)系 在解答

64、狀語(yǔ)從句考題時(shí),首先,考生對(duì)從屬連詞的基本用法、基本含義必須爛熟于心;其次,在解題時(shí),考生應(yīng)根據(jù)句意和主、從句之間的邏輯關(guān)系選擇恰當(dāng)?shù)膹膶龠B詞。不同的從屬連詞,其功能有所區(qū)別,較為容易選擇,但有的連詞形式一樣,含義不同,這就需要考生仔細(xì)甄別,充分利用與之相關(guān)的內(nèi)容或與其搭配的相關(guān)詞語(yǔ)的意思來(lái)判斷狀語(yǔ)從句的類別。,例1In the global economy,a new drug for cancer,it is discovered,will create many economic possibilities around the world. A.whateverB.whoeverC.w

65、hereverD.whichever,解析根據(jù)本題句意,主干內(nèi)容是說(shuō)在全球經(jīng)濟(jì)中,一種治療癌癥的新藥會(huì)在全世界創(chuàng)造很多經(jīng)濟(jì)機(jī)會(huì)。 it is discovered應(yīng)該表示“無(wú)論它是在哪里被發(fā)現(xiàn)”。由此可見,本題考查讓步狀語(yǔ)從句。若考生熟知whatever, whoever, wherever和whichever的意思,就很容易確定此處應(yīng)用wherever來(lái)引導(dǎo)讓步狀語(yǔ)從句。讓步狀語(yǔ)從句一般在主句之前或之后,但是本題命題者有意把從句置于主句中間,這無(wú)疑會(huì)迷惑考生,增加了考題的難度。考生在解題時(shí)可以把它調(diào)整為自己熟悉的結(jié)構(gòu)。,例2The majority of new businesses fai

66、l because, they have a product or service that fills a gap in the market, they usually lack the skills in sales, marketing, and administration. A.now thatB.even if C.as long asD.as though,解析本題中的because引導(dǎo)原因狀語(yǔ)從句來(lái)說(shuō)明大多數(shù)新的公司失敗的原因;而在原因狀語(yǔ)從句中還包含一個(gè)讓步狀語(yǔ)從句,表示“即使這些新公司有產(chǎn)品或服務(wù)填補(bǔ)市場(chǎng)空缺,但它們經(jīng)常缺少在銷售、營(yíng)銷和管理方面的技巧”。now that既然,引導(dǎo)原因狀語(yǔ)從句;as long as只要,引導(dǎo)條件狀語(yǔ)從句;as though好像,常引導(dǎo)方式狀語(yǔ)從句。even if盡管,引導(dǎo)讓步狀語(yǔ)從句,符合語(yǔ)境,故選B項(xiàng)。,
