確性，故選D。19．推理判斷題。根據(jù)“Thesecondgroupwastoldtodrawthelinesoutsidetheimaginedbox.Guesswhat?Onlyalittlemorethan20percentsolvedthepuzzle,whichisnobigdifferencefromtheresultofGuilford’sexperiment.”可知，就算有明確的指示，第二隊(duì)也只有20%多一點(diǎn)點(diǎn)的人解決了這個(gè)謎題，換句話說(shuō)，即使有明確的指示也幾乎沒(méi)有人做的更好，故選C。20．標(biāo)題歸納題。通讀全文可知，文章主要介紹了20世紀(jì)70年代，一位名叫J.P.Guilford的心理學(xué)家進(jìn)行了一項(xiàng)著名的關(guān)于創(chuàng)造力的研究，名為“九點(diǎn)謎題”，這讓Guilford得出了一個(gè)籠統(tǒng)的結(jié)論：創(chuàng)造力需要你跳出框框。但是后來(lái)有人通過(guò)研究證明這個(gè)結(jié)論是一個(gè)誤導(dǎo)。所以選項(xiàng)C“跳出思維定勢(shì)：一個(gè)誤導(dǎo)性的想法”是最好的標(biāo)題，故選C。21．D22．B23．D24．B【導(dǎo)語(yǔ)】本文主要講述了動(dòng)物也會(huì)撒謊，撒謊可以幫助它們生存。21．細(xì)節(jié)理解題。根據(jù)第二段的第二句話“Forexample,abirdcalledtheploversometimespretendstobehurtinordertoprotectitsyoung.”可知啄木鳥(niǎo)保護(hù)孩子不受獵食動(dòng)物侵害是通過(guò)假裝受傷，故選D。22．詞句猜測(cè)題。根據(jù)第五段的最后一句“Butananimalexpertoncesawalosingchimptakethewinner’shandandstartfightingagain.”（一個(gè)輸了的大猩猩抓住獲勝的大猩猩的手又開(kāi)始打斗了）可知，這句話的意思是大猩猩也可能不誠(chéng)實(shí)，故選B。23．細(xì)節(jié)理解題。根據(jù)文章第六段“Butsomecleverchimpslearntocryverysoftlywhentheyfindfood.Thatway,otherchimpsdon’thearthem,andtheydon’tneedtosharetheirfood.”可知，一些大猩猩放低它們的叫聲，這樣讓別的大猩猩得不到食物，故選D。24．主旨大意題。根據(jù)全篇文章的內(nèi)容和第一段第二行的句子“Cantheyliewiththeirbodiesandbehavior?”可知這篇文章講的是動(dòng)物也會(huì)撒謊，故選B。25．D26．D27．C28．D29．D【導(dǎo)語(yǔ)】本文主要講述了新冠肺炎疫情期間挽救人命的口罩，如今卻成了野生動(dòng)物的“殺手”。作者呼吁人們使用口罩后，勿隨意丟棄。25．細(xì)節(jié)理解題。根據(jù)“thatalsomeanssingle-usefacemasks,gloves,andotherPPEarethenewestformsofrubbishoncitystreets,beaches,andintheocean.”可知一次性口罩、手套和其他個(gè)人防護(hù)裝備是最新的垃圾形式。故選D。26．詞句猜測(cè)題。根據(jù)“Facemasksaren’tgoingawaysoon”可知口罩不會(huì)很快消失，即要花費(fèi)很長(zhǎng)時(shí)間才能消失。故選D。27．細(xì)節(jié)理解題。根據(jù)“Monkeyshavebeenfoundbitingthestraps(帶子)ofusedmasksinthehillsoutsideMalaysia’scapitalKualaLumpur...InBritain,aseabird”可知作者通過(guò)猴子和海鳥(niǎo)的例子講述了亂扔口罩對(duì)動(dòng)物的危害。故選C。28．推理判斷題。根據(jù)“Thesedays,wearingafacemask(口罩)isacommonthingtodo,andithelpspreventdiseasesduringCOVID-19”以及“Pleasedon’tletthemasksbecomeani
