/英語閱讀理解解題技巧、解題步驟英語閱讀理解解題技巧-解題步驟

王老師說，同學(xué)們?cè)谧鲩喿x理解時(shí)，可遵循三部曲的原則，即：快速閱讀短文;認(rèn)真逐題作答;復(fù)查校對(duì)答案。

第一步，快速閱讀短文;通讀測(cè)試題，明確考查點(diǎn)。

先讀題，明確題目要求，弄清考點(diǎn)，然后帶著問題去讀文章，這種方法在英語中稱為scanning，就是尋讀?？焖匍喿x一遍弄清段落大意，對(duì)全文有一個(gè)整體了解，閱讀時(shí)從宏觀入手，掌握中心意思，注意哪些用以說明中心意思的主要事實(shí)和細(xì)節(jié)，抓住關(guān)鍵詞，弄清作者寫此篇文章的目的及意圖。如遇到生詞，應(yīng)先跳過，繼續(xù)通讀全文，切忌長時(shí)間死扣生詞，因?yàn)橛行┥~并不影響對(duì)全文的理解，還有一些詞可以通過上下文推測(cè)含義。

第二步，認(rèn)真逐題作答。

看完短文后，對(duì)整篇短文的內(nèi)容有了大致的了解，然后馬上看后面的問題，帶著問題去找答案。如果屬于客觀信息題，就可直接在短文中找到出處。如果是主觀判斷題，則應(yīng)迅速再讀全文，仔細(xì)分析思考，將近似的答案對(duì)照原文反復(fù)比較，推敲，選出最佳答案。

第三步，仔細(xì)校對(duì)所選答案。

做完所有題目后，再讀一遍短文，逐一檢查所有答案是否有誤。如果有拿不定主意的答案，不要隨意更改。一定要從原文中找到依據(jù)，方可更正。

-閱讀技巧

①要快速瀏覽全文，掌握主旨和大意，特別注意文章的主題句，理出作者的寫作思路。(Whatistheidea?Whatarefacts?)

②要盡快瀏覽課文后的思考題，盡量帶著問題讀;

③完成事實(shí)細(xì)節(jié)題時(shí)，要找到定位句;

④要把有關(guān)WHO，WHAT，WHERE，HOW和WHY等方面內(nèi)容用筆圈畫出來。

⑤遇到推理判斷題時(shí)，要注意作者的態(tài)度和命題人的意圖，不可從個(gè)人的經(jīng)驗(yàn)出發(fā)?！白鲇⒄Z閱讀理解時(shí)，答題也有講究。如果同學(xué)們具備一定的答題技巧，那么最終將事半功倍?！蓖趵蠋熣f，做猜測(cè)詞義題、細(xì)節(jié)理解題、主旨?xì)w納題、推理判斷題都有一定的技巧。

英語閱讀理解解題技巧??一、猜測(cè)詞義題

閱讀理解經(jīng)常會(huì)遇到生詞，這些生詞怎么解決呢?這就需要一些猜詞的技巧。

(一)根據(jù)生活常識(shí)猜測(cè)詞義

Childrenarealwaysboasting.Theysaythingslike“MyDad'scarisbiggerthanyourDad's，”“MyMomissmarterthanyours.”and“Myfamilyhasmoremoneythanyours.”

Theword“boasting”means__B___

A.驕傲B.吹牛C.頑皮D.幼稚

Manyplantsandanimalsaregoingextinct.Mammoths，whicharerelated(有關(guān)聯(lián)的)withAsiaelephants，arenowextinct.Therearenomammothsintheworldtoday.

1.Amammothisakindof_C___.

A.plantB.birdC.animalD.tree

2.Thewordextinctmeans_C_

A.出現(xiàn)B.危險(xiǎn)C.滅絕

Usuallypeoplemakedumplingsathome.Ifyouhavenotimetomakethem，youcanbuythemfromanysupermarket.Thenyoutakethemhomeandeatthemwithvinegar.

Theword“vinegar”means醋

Waterismadefromoxygenandhydrogen.

Thewords“oxygenandhydrogen”mean氫和氧

(二)根據(jù)上下文的意思來猜測(cè)

1.Somepeopleliketowalkquicklyhomeafterwork，butIprefertostrollhomeandlookatthestorewindowsalongtheway.(溜達(dá))

2.Sheisusuallypromptforallherclasses，buttodayshearrivesquitelate.(準(zhǔn)時(shí)的)

3.ThedoorissolowthatIhitmyheadonthelintel.(門梁)

(三)根據(jù)轉(zhuǎn)折、因果關(guān)系猜測(cè)詞義

通過因果關(guān)系猜詞，首先是找出生詞與上下文之間的邏輯關(guān)系，然后才能猜詞。有時(shí)文章借助關(guān)聯(lián)詞(如because，as，since，for，so，thus，asaresult，ofcourse，therefore等等)表示前因后果。例如：

Youshouldn'thaveblamedhimforthat，foritwasn'thisfault.通過for引出的句子所表示的原因(那不是他的錯(cuò))，可猜出blame的詞義是“責(zé)備”。

(四)通過同義詞和反義詞的關(guān)系猜詞

通過同義詞猜詞，一是要看由and或or連接的同義詞詞組，如happyandgay，即使我們不認(rèn)識(shí)gay這個(gè)詞，也可以知道它是愉快的意思;二是看在進(jìn)一步解釋的過程中使用的同義詞，如ManhasknownsomethingabouttheplanetsVenus，Mars，andJupiterwiththehelpofspaceships.此句中的Venus(金星)、Mars(

火星)、Jupiter(木星)均為生詞，但只要知道planets就可猜出這幾個(gè)詞都屬于“行星”這一義域。通過反義詞猜詞，一是看表轉(zhuǎn)折關(guān)系的連詞或副詞，如but，while，however等;二是看與not搭配的或表示否定意義的詞語，如：Heissohomely，notatallashandsomeashisbrother.根據(jù)notatall...handsome我們不難推測(cè)出homely的意思，即不英俊、不漂亮的意思。

(五)通過構(gòu)詞法猜詞

在閱讀文章時(shí)，總會(huì)遇上一些新詞匯，有時(shí)很難根據(jù)上下文來推斷其詞意，而它們對(duì)文章的理解又有著舉足輕重的作用，此時(shí)，如掌握了一些常用的詞根、前綴、后綴等語法知識(shí)，如前綴un-表反義詞，如happy、unhappy，fair、unfair，important、unimportant等;后綴-ment表名詞，如develop、development，state、statement，argue、argument等;后綴-er、-or或-ist表同源名詞;如calculate、calculator，visit、visitor，law、lawyer，wait、waiter，sci-ence、scientist，art、artist等，這些問題便不難解決了。

(六)通過定義或釋義關(guān)系來推測(cè)詞義

例如：Butsometimes，norainfallsforalong，longtime.Thenthereisadryperiod，ordrought.從drought所在句子的上文我們得知很久不下雨，于是便有一段干旱的時(shí)期，即drought，由此可見drought意思為“久旱”，“旱災(zāi)”。而adryperiod和drought是同義語。這種同義或釋義關(guān)系常由is，or，thatis，inotherwords，becalled或破折號(hào)等來表示。

(七)通過句法功能來推測(cè)詞義

例如：Bananas，oranges，pineapples，coconutsandsomeotherkindoffruitgrowinwarmareas.假如pineapples和coconuts是生詞，可以從這兩個(gè)詞在句中所處的位置來判斷它們大致的意思。從句中不難看出pineapples，coconuts和bananas，oranges是同類關(guān)系，同屬fruit類，因此它們是兩樣水果，準(zhǔn)確地說，是菠蘿和椰子。

(八)通過描述猜詞

描述即作者為幫助讀者更深更感性地了解某人或某物而對(duì)該人或該物作出的外在相貌或內(nèi)在特征的描寫。例如：ThepenguinisakindofseabirdlivingintheSouthPole.Itisfatandwalksinafunnyway.Althoughitcannotfly，itcanswimintheicywatertocatchthefish.從例句的描述中可以得知penguin是一種生活在南極的鳥類。后面更詳盡地描述了該鳥類的生活習(xí)性。英語閱讀理解解題技巧二、細(xì)節(jié)理解題

首先瀏覽一遍題目，看清題目要求理解什么細(xì)節(jié)，然后有選擇性地在文中找出相應(yīng)的段落句子或短語，認(rèn)真分析理解，選出正確答案。
