D.Trytocreatenewwords.推理判斷題推理判斷題,通常應(yīng)注意以下兩點(diǎn):(1)特別留心特定細(xì)節(jié)所謂“特定細(xì)節(jié)”,就是問題所涉及的范圍和對象中的細(xì)節(jié)事實(shí)。它一般包括事實(shí)根據(jù)、名字(人物或地點(diǎn))、數(shù)字(日期或統(tǒng)計(jì)數(shù)字)、關(guān)鍵詞語的其他表達(dá)方法(同義詞、近義詞、反義詞)等。(2)注意作者的語氣和態(tài)度作者的語氣和態(tài)度通常體現(xiàn)在短文所使用的措辭和句式上。要特別注意感情色彩比較濃重的形容詞和副詞,特別留心短文句子的長度和結(jié)構(gòu)。從措辭上我們可以推斷出作者對所討論話題的態(tài)度;從句式的長短和結(jié)構(gòu)可以判斷出作者討論問題的語氣。主旨大意題(1)留心關(guān)鍵詞,抓住文章主旨;串聯(lián)主要細(xì)節(jié),推斷文章中心思想。所謂關(guān)鍵詞,即文章中反復(fù)出現(xiàn)的、與主題有關(guān)的諸如名詞、動詞等,冠詞或介詞等詞均不在關(guān)鍵詞之列。需要注意的是,為了避免同一詞的過多重復(fù),文章有時(shí)會使用這個(gè)詞的同義詞、近義詞或代詞指代。我們知道,并不是所有文章都包含明確的主題句,比如大多數(shù)的記敘文。記敘文的中心思想多隱藏在具體的細(xì)節(jié)中,作者通過眾多的細(xì)節(jié)事實(shí)對一個(gè)中心點(diǎn)進(jìn)行論述。因此,我們必須善于串聯(lián)主要細(xì)節(jié),從中歸納文章的中心思想。(2)注意段落主題句,歸納文章大意。段落的主題通常由被稱為主題句的句子來表示。主題句有兩個(gè)功能:①介紹段落的主題;②闡述控制概念,控制概念用以控制段落中句子討論的內(nèi)容。主題句通常是一段的第一句或末尾一句,偶爾在一段中間。我們在閱讀非故事性文章如科普文章的時(shí)候,主題句尤為明顯。有的文章無明顯的主題句,主題句隱含在段意之中。①主題句位于段首主題句位于段首是由作者先立論點(diǎn),后擺事實(shí)講道理的寫作手法形成的。這種段落稱作演繹型段落。據(jù)有關(guān)統(tǒng)計(jì)數(shù)字表明,在英語議論文或說明文中,有60%~90%的主題句是段落的第一句。a.尋找主題句有些段落有明顯的引出細(xì)節(jié)的信息詞,常見的信息詞有:forexample,anexampleof,themostimportantexample,first,second,next,then,last,finally,tobeginwith,also,besidesthat等。在閱讀中,應(yīng)盡量利用上述信息詞確定主題句的位置。如果無明顯的信息詞,可先假設(shè)第一句為主題句,在第二句前面添加一個(gè)forexample,看看第二句是否可以支撐第一句話,如果第二句不能支撐第一句話,便在其他地方找出主題句。b.選擇答案先徹底弄懂主題句的句意,然后閱讀所給的選項(xiàng),選擇與主題句句意相吻合的答案,如主題句的再現(xiàn),主題句句意的復(fù)述或推論等,排除與主題句句意無關(guān)的答案,如支撐細(xì)節(jié)和文章中未曾闡述的事實(shí)等。②主題句位于段末主題句位于段末是作者采用了先擺事實(shí),后做結(jié)論的手法。這種段落稱作歸納型段落。③主題句位于段落的中間主題句偶爾也出現(xiàn)在段落的中間,但不一定就在正中間。有時(shí),第一句并非主題句,而是承上啟下的過渡句。在這種情況下,第二句便成了主題句。此外,主題句也可能是段落的倒數(shù)第二句。一Plantsaremorethanjustprettytolookat.Theygiveusfruits,vegetablesandfoodweeat.Someplantsevenprovidematerialsformedicineorbuildingthings.Butdoyouknowthatplantscandosomethingevenmoreamazing?Theycanmakeourhomes,schoolsandworkplacesmuchhealthier.Wespendalargepartofourdayindoors.Unluckily,theairinsidebuildingscanoftenbefullofchemicals(化學(xué)物質(zhì))frommanythingsaroundus.Thispoorairquality(質(zhì)量)canmakeusfeelsick,causingsoreeyesandthroats,andevenmakingithardforustobreathe.Whentheairinsidebuildingsgetsreallybad,peopleevencallthem“sickbuildings”.Thegoodnewsisthatplantsarelikenature'slittlesuperheroes.Theyhaveamagicpowerfightingagainstbadair.Plantsbreatheincarbondioxide(CO2)andbreatheoutoxygen(O2)whichwehumansneedtolive.Theycanalsoaddmoisturetotheairifit'stoodry,makingitmorecomfortableforustobreathe.▲Scientistshavediscoveredthatplantshavetheabilitytotakeinharmfulchemicals,makingtheairaroundussafertobreathe.Theysetupacompletelyclosedbuildingcalled“bio-home”forexperiments.Beforetheyaddedplants,theairinsidewasfullofchemicalsandpeoplefoundithardtobreathe.Butaftertheyaddedplants,theairgotmuchcleaneranditbecameeasiertobreathe.Tomaketheairinsideevenbetter,thescientistsuseddifferentkindsofplants.Afterawhile,thebuildingwasn'ta“sickbuilding”anymore.Peoplecouldgoinsidewithoutfeelingunwell.
