這是一篇應(yīng)用文。文章主要介紹了四個(gè)國(guó)家中,那些可以讓人們回顧過(guò)去的著名景點(diǎn)。

21.

細(xì)節(jié)理解題。根據(jù)第一部分的Wewillvisitsomeofthebest-preservedRomanmonumentsintheworld.(我們將參

觀一些世界上保存最完好的羅馬建筑遺跡)和第二部分的weexplorehistoricalmonumentsandarchitecture.(我們

探索歷史遺跡和建筑)可知,在ClassicalProvence和SouthernSpain游客們可以參觀歷史遺跡。A.Historical

monuments(歷史遺跡)符合以上說(shuō)法,故選A項(xiàng)。

22.

推理判斷題。根據(jù)第三部分的China'sSacredLandscapes(21days)(中華神山21天)和DiscovertheChinaof"past

ages**,itswalledcities,templesandmountainscenerywithProfRobertThorp.HighlightsincludeChina'smostsacred

去,有墻的城市、寺廟和山景。精彩之處包括中國(guó)最神圣的泰山之巔,杭州起伏的群山、運(yùn)河和寧?kù)o的寺廟)

可知,去中國(guó)的神山之行總共有27天,而且Thorp對(duì)中國(guó)的名山非常了解。由此推測(cè)Thorp在這四個(gè)國(guó)家里

最了解中國(guó)。C.China(中國(guó))符合以上說(shuō)法,故選C項(xiàng)。

23.

細(xì)節(jié)理解題。根據(jù)第四部分的TourhighlightsincludetheRomancityofDougga,theundergroundMumidian

capitalatBullaRegia,RomanSbeitlaandtheremoteareasaroundTaraounineandMatmata,uniqueforunderground

以及在Taraounine和Matmata附近的區(qū)域,它們是獨(dú)特的地下城市)可知,突尼斯的旅游亮點(diǎn)是地下城市。B.

Undergroundcilies(地下城市)符合以上說(shuō)法,故選B項(xiàng)。

這是一篇新聞報(bào)道。短文報(bào)道了電影“猩球崛起”上個(gè)月首次與公眾見(jiàn)面。動(dòng)物愛(ài)好者聚集在好萊塢前,感

謝電影制作者,在電影拍攝時(shí),沒(méi)有使用真的類(lèi)人猿。現(xiàn)在的動(dòng)物拍攝使用的是數(shù)字化人猿的創(chuàng)造技術(shù),而

一些電影的拍攝卻存在著虐地動(dòng)物的現(xiàn)象,這讓一個(gè)非盈利的組織密切關(guān)注此事。但有些拍攝也是不能夠被

監(jiān)測(cè)到的。

24.

細(xì)節(jié)理解題。根據(jù)第一段“Instead,oneactivist,dressedinafull-bodymonkeysuit,hadarrivedwithasign

praisingthefilmmakers:uThanksfornotusingrealapes,,可知,相反,一名身穿全套猴服的活動(dòng)人士來(lái)到現(xiàn)

場(chǎng),手里拿著一塊牌子,稱贊電影制作人:“感謝你們不用真正的猿猴。所以動(dòng)物保護(hù)者聚集在好萊塢大道是

為了向電影制作者表示感謝。故選D項(xiàng)。

25.

主旨大意題。根據(jù)第二段“ThecreativeteambehindHApes'*usedmotion-capture(動(dòng)作捕捉)technologytocreate

digitalizedanimals,spendingtensofmillionsofdollarsontechnologythatIrecordsanactorJsperformanceand

laterprocessesitwithcomputergraphicstocreateafinalimage(圖像)."可知,“人猿”背后的創(chuàng)作團(tuán)隊(duì)利用動(dòng)

作捕捉技術(shù)創(chuàng)造數(shù)字化的動(dòng)物,在記錄演員表演的技術(shù)上,花費(fèi)數(shù)千萬(wàn)美元,然后用電腦圖形處理,以產(chǎn)生

最終的影像。由此可知,第二段主要是關(guān)于數(shù)字化人猿的創(chuàng)造。故選B項(xiàng)。

26.

詞句猜測(cè)題。根據(jù)第三段劃線前的句子“Onenonprofitorganization,whichmonitorsthetreatmentoranimalsin

filmedentertainment(一個(gè)非營(yíng)利組織,監(jiān)控動(dòng)物在電影娛樂(lè)中的待遇)以及下文Already,anumberof

whosaythecreaturesactinginthemhaven'tbeentreatedproperly.(許多電影,包括“大象的眼淚”,“宿醉II”

和“管理員”,引起了動(dòng)物保護(hù)人士的憤怒,他們說(shuō)影片中的動(dòng)物沒(méi)有遭到很好的對(duì)待。)由此可知,其中一

家監(jiān)控動(dòng)物待遇的非營(yíng)利組織,今年正密切關(guān)注著2000多部影片。由此判斷出,劃線詞的意思是“密切關(guān)

注”。故選D項(xiàng)。

27.

推理判斷題。根據(jù)最后一段Insomecases,it'snotsomuchthetreatmentoftheanimalsonsetinthestudiothat

hasactivistsworried;it'stheoff-settrainingandlivingconditionsthatareraisingconcerns.Andtherearequestions

aboutthefilmsmadeoutsidetheStates,whichsometimesarenotmonitoredascloselyasproductionsfilmedinthe

Sates."(在某些情況下,讓活動(dòng)人士擔(dān)心的并不是電影棚里對(duì)動(dòng)物的待遇;讓人擔(dān)憂的是訓(xùn)練和生活條件。

還有一些關(guān)于在美國(guó)以外拍攝的電影的問(wèn)題,這些電影有時(shí)不像在美國(guó)拍攝的電影那樣受到嚴(yán)密的監(jiān)控。)可

31.D

【解析】

【分析】

這是一篇新聞報(bào)道。短文報(bào)道了在英國(guó),由于年輕人負(fù)擔(dān)不起離家的費(fèi)用,而老年人又面臨著被孤立的風(fēng)

險(xiǎn),越來(lái)越多的家庭選擇住在一起,出現(xiàn)了多世同堂的現(xiàn)象。

28.

細(xì)節(jié)理角吊題。根據(jù)第三段“butRitaWhiteheadhasherownkitchen,bathroom,bedroomandlivingroomonthe

groundfloor.”可知,但Rita在一樓有自己的廚房、浴室、臥室和客廳。由此可知,Rita在布里斯托爾的維多

利亞式住宅中使用一樓。故選B項(xiàng)。

29.

推理判斷題。根據(jù)第五段“AndwhatdoesNickthink?”Frommystandpoint,itallseemstoworkverywell.WouldI

recommendit?Yes,IthinkIwould.”可知,尼克是怎么想的?”從我的角度來(lái)看,一切都很順利。我推薦它嗎?是

的,我想我會(huì)推薦在一起居住的?!庇纱伺袛喑?,尼克對(duì)和和岳母合住房子的態(tài)度是積極的。故選A項(xiàng)。

30.

細(xì)節(jié)理解題。根據(jù)第六段“Officialreportssuggestthatthenumberofhouseholdswiththreegenerationsliving

togetherhadrisenfrom325,000in2002to419,000in2013.”官方報(bào)告顯示,三代同堂的家庭數(shù)量從2002年的

32.5萬(wàn)戶增加到2013年的41.9萬(wàn)戶。根據(jù)第七段“Itissaidthatabout20%of25-34-year-oldslivewiththeir

parents,comparedwith16%in1991.ThetotalnumberofallmultigenerationalhouseholdsinBritainisthoughttobe

about1.8million.”可知,據(jù)說(shuō),25-34歲的年輕人中有20%和父母住在一起,而1991年這一比例為16%。據(jù)

估計(jì),英國(guó)多代同堂的家庭總數(shù)約為180萬(wàn)。由此可知,作者關(guān)于多世同堂家庭的論述基于發(fā)布的統(tǒng)計(jì)數(shù)

據(jù)。故選C項(xiàng)。

31.

主旨大意題。通讀全文,尤其根據(jù)第一段"Withtheyoungunabletoaffordtoleavehomeandtheoldatriskof

isolation(孤獨(dú)),morefamiliesarechoosingtolivetogether.”可知,由于年輕人負(fù)擔(dān)不起離家的費(fèi)用,而老年人又

面臨著被孤立的風(fēng)險(xiǎn),越來(lái)越多的家庭選擇住在一起。所以短文主要是關(guān)于英國(guó)生活方式的一種上升趨勢(shì)。

故選D項(xiàng)。

thousandyears.(我們是進(jìn)化的產(chǎn)物,而且不僅僅是數(shù)十億年前的產(chǎn)物。當(dāng)科學(xué)家更深入的研究我們的基因

時(shí),他們發(fā)現(xiàn)了人類(lèi)在過(guò)去幾千年進(jìn)化的例子)可知,作者列舉第一段的例子是為了告訴我們關(guān)于人類(lèi)進(jìn)化的

一個(gè)新信息,那就是人類(lèi)在最近幾千年也在進(jìn)化。B.Newknowledgeofhumanevolution4人類(lèi)進(jìn)化的新知識(shí))

符合以上說(shuō)法,故選B項(xiàng)。

33.

屋上;最近他們也把房子建在沿海水域的吊腳樓上)可知,Bajau把房子建在沿海區(qū)域。D.Offthecoast.(沿海)

符合以上說(shuō)法,故選D項(xiàng)。

34.
