劍橋雅思14Test4Passage1閱讀答案解析
第1題答案:four/4
對應(yīng)原文:第3段:Giraldo focused on ants at four age ranges: 20 to 22 days, 45 to 47 days, 95 to 97 days and 120 to 122 days
答案解析:文章在經(jīng)過前兩段的鋪墊之后,從第3段開始講述Ysabel Giraldo的研究,因此我們將目光主要集中在第三段,根據(jù)focused on定位到這句話,原文中明確指出是4個年齡段,由此確定答案為4。
第2題答案:young
對應(yīng)原文:第4段:Giraldo watched how well the ants took care of the young of the colony
答案解析:對螞蟻行為的研究主要集中在第4段,題干中l(wèi)ook after與took care of同義替換,由此確定答案為young。
第3題答案:food
對應(yīng)原文:第4段:She compared how well 20-day-old and 95-day-old ants followed the telltale scent that the insects usually leave to mark a trail to food.
答案解析:根據(jù)scent trail定位到這句話,空前詞為locate,即尋找、定位、跟蹤什么東西,原文中只有food填上去語義合適,由此鎖定答案。
第4題答案:light
對應(yīng)原文:第4段:She tested how ants responded to light
答案解析:順著上一題往下,第三個研究項目為螞蟻對光線的反應(yīng),由此確定答案為light。
第5題答案:aggressively
對應(yīng)原文:第4段:And she experimented with how ants react to live prey: a tethered fruit fly … And when it came to reacting to prey, the older ants attacked the poor fruit fly just as aggressively as the young ones did
答案解析:根據(jù)prey先定位到第4段的中部,但這句話里并沒有什么副詞可以填到空中,因此繼續(xù)往下尋找,發(fā)現(xiàn)段末還有一句關(guān)于捕食的描述,其中提到老年螞蟻跟年輕螞蟻一樣富有侵略性。aggressively無論是詞義還是詞性都符合題目要求,由此確定為答案。
第6題答案:location
對應(yīng)原文:第5段:She saw no major differences with age, nor was there any difference in the location of the dying cells
答案解析:螞蟻大腦的相關(guān)內(nèi)容主要集中在第5段,看到小標(biāo)題后將注意力轉(zhuǎn)移到該部分。根據(jù)dying cells定位到第5段的前兩句話,從題干結(jié)構(gòu)可以看出,空上要填一個與age并列的詞匯,由此確定location為答案。
第7題答案:neurons
對應(yīng)原文:第5段:She also wanted to see if aging affects the density of synaptic complexes within these structures—regions where neurons come together.
答案解析:根據(jù)synapitic complexes定位到第5段的這句話,in which與where同義替換,meet與come together對應(yīng),根據(jù)句子結(jié)構(gòu)確定答案為neurons。
第8題答案:chemicals
對應(yīng)原文:第5段:the old ants didn’t experience any drop in the levels of either serotonin or dopamine—brain chemicals whose decline often coincides with aging
答案解析:根據(jù)two與serotonin和dopamine對應(yīng)定位到這句話,它們兩個都是大腦中化學(xué)物質(zhì),由此確定chemicals為正確答案。
第9題答案:FALSE
對應(yīng)原文:第2段:Naked mole rats can live for almost 30 years and stay fit for nearly their entire lives.
答案解析:第2段第2句提到:“裸鼢鼠可以活將近30年的時間,并且在一生中都保持健康”??梢娺@種生物也能夠remain active for almost their whole lives,題干中“Pheidole dentata是唯一已知動物”的描述與此不符,因此判斷答案為FALSE。
第10題答案:TRUE
對應(yīng)原文:第3段:Unlike all previous studies … her work tracked the ants from the time the pupae became adults, so she knew their exact ages.
答案解析:第3段中間提到,“與所有之前的研究不同,她從蛹變成成蟲開始追蹤螞蟻,所以知道它們的確切年齡”。題干中的first person對應(yīng)unlike all previous studies,precise data about the insects’ age對應(yīng)exact ages,即題干中的主要信息點(diǎn)在原文中都能找到對應(yīng),由此判斷答案為TRUE。
第11題答案:FALSE
對應(yīng)原文:第4段:Giraldo expected the older ants to perform poorly in all these tasks. But the elderly insects were all good caretakers and trail-followers
答案解析:第4段靠后位置提到,“Giraldo預(yù)計老年螞蟻會在所有任務(wù)中表現(xiàn)較差。但這些老年昆蟲都是優(yōu)秀的幼蟲照顧者和痕跡追蹤者”。可見實(shí)驗結(jié)果與Giraldo的預(yù)期并不一致,由此判斷題干為FALSE。
第12題答案:NOT GIVEN
對應(yīng)原文:第6段:Scientists have looked at some similar aspects in bees, but the results of recent bee studies were mixed
答案解析:原文中確實(shí)提到針對蜜蜂的研究,但只是說實(shí)驗結(jié)果混雜,并沒有提到研究方法方面的內(nèi)容,因此判斷答案為NOT GIVEN。
第13題答案:TRUE
對應(yīng)原文:第3段:In the lab, P. dentata worker ants typically live for around 140 days
第7段:Out in the wild, the ants probably don’t live for a full 140 days thanks to predators, disease and just being in an environment that’s much harsher than the comforts of the lab.
答案解析:原文第3段指出,P. dentata在實(shí)驗室里一般可以活到140天左右。然后第7段又提到,“野外環(huán)境中,因為種種原因,螞蟻可能活不到140天”??梢妼?shí)驗室中的螞蟻活的更久,由此判斷答案為TRUE。
