seahare【答案】（1）C（2）B（3）C【解析】【分析】本文是一篇說明文，介紹了一些野生動(dòng)物是如何進(jìn)行自身防御的。（1）考查細(xì)節(jié)理解。根據(jù)

SeaHare(海兔)部分中的“Theseaharegivesoutaslimy,purpleink,thesubstancewhichmakesfoodlesspalatabletopredators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質(zhì)使得捕食者對(duì)食物不那么感興趣，從而保護(hù)自己免受捕食者的傷害。故選C。（2）考查細(xì)節(jié)理解。根據(jù)

Opossum(負(fù)鼠)部分中的“Inordertobecome‘dead’,theydon'thavetofaxanyoneadeathcertificate.Theyjustlietherewiththeirtongueshangingoutwiththesmellofdeadflesh,sometimesforhours,effectivelyconvincingpotentialpredatorstheycanfindamuchfreshermealelsewhere.”可知，負(fù)鼠假裝死亡，讓捕食者在其他地方找到更新鮮的食物，以避免成為捕食者的目標(biāo)。故選B。（3）考查推理判斷。根據(jù)Millipedes(千足蟲)部分中的“Theirmajordefenseistocurlupintoaball.They,though,alsoreleaseaharmeyes,andleaveahorriblesmellontheirattackers.”可知，千足蟲主要防守是蜷成一團(tuán)。然而，它們也會(huì)釋放出有害的

眼睛，并在攻擊者身上留下可怕的氣味。從而可以推斷出，千足蟲是擁有多種防御機(jī)制的物種。故選C。【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。4．犇犇閱讀下面文章，然后從題中所給的A、B、C、D四個(gè)選項(xiàng)中，選出每個(gè)問題的最佳選項(xiàng)。

Shiningcolorsasasexualstrategy【答案】（1）D（2）C（3）C（4）B【解析】【分析】本文是一篇說明文，介紹了彩虹色有助于生物隱藏。（1）考查細(xì)節(jié)理解。根據(jù)第一段中的“Agooddisguisekeepsyouhidden,right?Well,sometimesthebestdisguiseisactuallythemostdazzlingbecauseresearchrevealsthatflashymetalliciridescence(金屬彩虹色)canvisuallypuzzlepredators,whichallowscolorfulpreytosurviveanotherday.”可知彩虹色被動(dòng)物用來通過逃離捕食者而活得更久，排除A；根據(jù)第三段中的“HereIwouldliketopointoutthatinsomespecies,particularlythosethatdisplaystrongsexualdimorphism(雌雄兩性),suchasbirdsofparadiseorsomebutterfliesorfishes,theoccurrenceofiridescenceismostlikelydrivenbysexualselection.”在這里我想指出的是，在某些物種中，尤其是那些表現(xiàn)出強(qiáng)烈兩性差異的物種，比如天堂鳥、孔雀，甚至在某些蝴蝶或魚類中，彩虹色的出現(xiàn)很可能是由性別選擇所驅(qū)動(dòng)的?？芍?jiǎng)游镉貌屎缟鹜榈淖⒁猓懦鼴；根據(jù)倒數(shù)第二段中的“Theideathateye-catchingcolorscouldbeusedasacover-upisn'tanewone.”引人注目的顏色可以用來偽裝，這種想法并不新鮮，排除C，故選D。（2）考查細(xì)節(jié)理解。根據(jù)最后一段中的“Itseemedthatthestrikinglyiridescentsurfacesonourtargetsvisuallybrokeuptheotherwiserecognizableshapeofthetargets,whichmadethemhardtodistinguish.”似乎我們的目標(biāo)上驚人的彩虹表面在視覺上打破了原本可以辨認(rèn)的目標(biāo)形狀，這使得它們很難區(qū)分。故選C。（3）考查推理判斷。根據(jù)最后一段說研究人員目前正在對(duì)鳥類進(jìn)行實(shí)驗(yàn)，這些鳥類的飲食中經(jīng)常含有彩虹色的昆蟲。實(shí)驗(yàn)?zāi)康氖强纯带B類的視角是否能提供幫助。由此推斷接下來一段會(huì)談?wù)摓槭裁带B類不受彩虹色昆蟲的影響，故選C。（4）考查主旨大意。第一段中的“Well,sometimesthebestdisguiseisactuallythemostdazzlingbecauseresearchrevealsthatflashymetalliciridescence(金屬彩虹色)canvisuallypuzzlepredators,whichallowscolorfulpreytosurviveanotherday.”有時(shí)，最好的偽裝其實(shí)是最耀眼的偽裝，因?yàn)檠芯勘砻?，閃光的金屬彩虹色能在視覺上迷惑捕食者，這讓五顏六色的獵物能夠再存活一天，是全文的主題句，結(jié)合全文內(nèi)容，可知這篇文章主要講了彩虹色有助于生物隱藏，故選B。【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。7．犇犇閱讀理解
