(P40)閱讀理解中長難句的理解技巧 近年來高考英語閱讀理解題加強(qiáng)了對長難句的考查，閱讀材料中出現(xiàn)了不少省略句、復(fù)雜單句和復(fù)雜復(fù)合句以及非謂語動(dòng)詞形式、獨(dú)立主格結(jié)構(gòu)等高級語法，有的復(fù)合句還采用多種從句疊現(xiàn)的復(fù)雜句型，來增強(qiáng)句子結(jié)構(gòu)的復(fù)雜性和語境理解的難度。要正確理解原文并解答試題，考生必須闖過長難句理解這一關(guān)，掃除閱讀障礙，提高解題信心。 技巧一：利用句子成分分析法理解長難單句 一般來說，在閱讀時(shí)沒有必要對短文進(jìn)行語法分析，但根

21、據(jù)語境含義分析句子是理解長難句的最有效方法。例1：With their shining brown eyes，wagging tails and unconditional love dogs can provide the nonjudgmental listeners needed for a beginning reader to gain confidence，according to Intermountain Therapy Animals (ITA) in Salt Lake City.點(diǎn)撥：該句含33個(gè)單詞，理解難度也很大。分析語境和句子成分可知，With their shin

22、ing brown eyes，wagging tails and unconditional love為with復(fù)合結(jié)構(gòu)作原因狀語，needed for a beginning reader to gain confidence為過去分詞作后置定語修飾listeners，according to Intermountain Therapy Animals (ITA) in Salt Lake City為介詞短語作條件狀語。句意為：根據(jù)鹽湖城ITA(的結(jié)論),這種狗長著明亮的棕色眼睛,搖動(dòng)著尾巴，擁有不附加任何條件的愛心。因此，這種狗可作為初學(xué)者獲取自信心，而且不會(huì)妄加評判的忠實(shí)聽眾。技巧二：抓

23、句子核心成分，簡化長句 分析長難句的核心成分，從句子層次入手，先抓主干，再理枝葉。例2：I am always amazed when I hear people saying that sport creates good will between the nations，and that if only the common people of the world could meet one another at football or cricket，they would have no inclination to meet on the battlefield.點(diǎn)撥：該句為主從復(fù)合

24、句，主句為I am always amazed，整個(gè)后面部分為時(shí)間狀語；在時(shí)間狀語中，分詞saying帶有兩個(gè)that引導(dǎo)的賓語從句，與saying一齊構(gòu)成分詞結(jié)構(gòu)作people的補(bǔ)語；在第二個(gè)賓語從句中，又有一個(gè)主從復(fù)合句，其中they would have no inclination to meet on the battlefield為主句，分句if only.or cricket是條件狀語從句。句意為：人們說體育運(yùn)動(dòng)可創(chuàng)造國家之間的友誼，還說如果各國民眾在足球場上交過手，就不愿在戰(zhàn)場上互相廝殺。每當(dāng)我聽到這么說時(shí)總是驚愕不已。 技巧三：用單句重排法準(zhǔn)確理解復(fù)合句 當(dāng)復(fù)合句中有很多從句疊現(xiàn)時(shí)，可以用單句重排法進(jìn)行簡化。例3：Literacy specialists admit that chi
