ī)的現(xiàn)象。1.A詞義猜測(cè)題。根據(jù)第二段中的“Thealgaegetsenergy...formanyorganismsthatlivethere.(藻類從陽光中獲得能量,并在內(nèi)部與珊瑚蟲分享。珊瑚蟲構(gòu)建了一個(gè)類巖石結(jié)構(gòu),構(gòu)成了大部分珊瑚礁,為生活在那里的許多生物提供了棲息地和食物。)”可知,珊瑚蟲和藻類有一種相互依賴的共存關(guān)系。A.可依賴的,可靠的;B.不受約束的,自由的;C.和諧的;D.相互矛盾的,對(duì)立的。分析選項(xiàng)可知A項(xiàng)最符合文意,故選A。2.C細(xì)節(jié)理解題。根據(jù)第一段中的“Therecordhightemperaturesensecoralbleaching.(創(chuàng)紀(jì)錄的高溫給珊瑚礁造成了極其緊張的環(huán)境,目前珊瑚礁也在經(jīng)歷嚴(yán)重的珊瑚白化。)”可知,創(chuàng)紀(jì)錄的高溫引起了珊瑚白化現(xiàn)象。故選C。3.B細(xì)節(jié)理解題。根據(jù)第三段中的“Thisincludesefforts...orgrowingandplantingcoralparts.Scientistsmovedmanycoralnurseriesinto...survivebestinthefuture.”可知,為了幫助珊瑚礁,科學(xué)家們尋找問題的原因、孵化珊瑚蟲卵、種植珊瑚枝節(jié)、轉(zhuǎn)移珊瑚苗圃、研究珊瑚蟲的DNA,而不是種植珊瑚蟲卵。故選B。4.D推理判斷題。根據(jù)最后一段中的“Therearesomebrightspotsinthestory,however.Somecoralshaverecoveredfromthebleaching,andmanydidnotbleachatall.(然而,這個(gè)故事也有一些有希望的地方。一些珊瑚蟲已經(jīng)從白化中恢復(fù)過來,還有許多珊瑚蟲根本沒有白化。)”可知,科學(xué)家們的努力有了成效。A.可識(shí)別的,可辨認(rèn)的;B.可預(yù)料的,意料之中的;C.影響深遠(yuǎn)的,廣泛的;D.有效的。故選D?！靖哳l詞匯】1.estimatedadj.估計(jì)的;估算的2.extremelyadv.極其;非常3.currentlyadv.目前;當(dāng)前4.intenseadj.強(qiáng)烈的;嚴(yán)肅緊張的5.makeup組成6.breakdown(關(guān)系)破裂/失敗;(系統(tǒng))癱瘓;(機(jī)器、車輛等)出故障;分解7.maintainv.保持;維持8.transferv.使轉(zhuǎn)移;轉(zhuǎn)讓;改變【差距詞匯】1.organismn.有機(jī)體;生物;(尤指)微生物2.skeletonn.框架;輪廓;骨架3.nurseryn.苗圃4.inducev.引起;導(dǎo)致長難句原句Thecoralbuildsarock-likestructure,whichmakesupmostofthecoralreef,providinghabitatsan
