不定式的完成時，表示先于謂語動詞發(fā)生的動作2013年，一張在挪威北極地區(qū)的斯瓦爾巴群島上發(fā)現(xiàn)了一只北極熊尸體的新聞?wù)掌尯芏嗳苏痼@。根據(jù)發(fā)現(xiàn)這只北極熊尸體的科學(xué)家的說法，這只北極熊只剩下“皮包骨頭”了。一位研究北極熊多年的專家說，從它尸體的位置看，這只熊似乎是餓死的。Expertsclaimed(專家稱,claimtodo宣稱做)thatlowsea-icelevelscausedbyclimatechange(過去分詞短語做后置定語)meantthebearcouldnothuntseals(捕食海豹)asbefore,soithadtotravelgreaterdistancesinordertofindfood.Thisalarmingcase(驚恐的案例)showedhowtheincreaseintemperaturehadanimpacton(對...有影響,influence,effect)Earth’secology(生態(tài)).專家稱，由于氣候變化造成的海冰水位較低，這只熊無法像以前那樣捕獵海豹，所以他為了找到食物不得不去更遠(yuǎn)的地方。這一令人震驚的案例表明氣溫升高對地球生態(tài)產(chǎn)生了怎樣的影響。Thenwhatiscausingtheincreaseintheglobalaveragesurfacetemperature(平均地表溫度)?Climatescientistsoftenmentionakey(關(guān)鍵的)climateprocesscalledthe“greenhouseeffect”(過去分詞短語做后置定語),which(引導(dǎo)非限定)hastwocommonmeanings:the“natural”greenhouseeffectandthe“man-made”greenhouseeffect.那么是什么正在導(dǎo)致全球表面平均溫度的上升呢？

氣候科學(xué)家經(jīng)常提到一個被稱為“溫室效應(yīng)”的關(guān)鍵氣候過程，它有兩個普遍的含義：“自然”溫室效應(yīng)和“人為”溫室效應(yīng)。The“natural”greenhouseeffectreferstothefactthat(引導(dǎo)同位語從句,解釋說明fact的具體內(nèi)容)heatfromthesunenterstheatmosphereandwarmsEarth’ssurfaceasshort-waveradiation(短波輻射).

Theheatisreleased(釋放)backintospaceatlongerwavelengths(波長).“自然”溫室效應(yīng)指的是來自太陽的熱量進(jìn)入大氣層，并以短波輻射的形式使地球表面升溫。熱量以更長的波長釋放回太空。Greenhousegasesintheatmosphere,suchasmethane(甲烷，沼氣)andcarbondioxide(二氧化碳),trapsomeoftheheat(困住/吸收熱量),keeping(現(xiàn)在分詞短語做結(jié)果狀語)Earth’sclimatewarmandhabitable(適宜居住).Withoutthisprocess,Earthcouldnotsustain(維系)life.However,the“man-made”greenhouseeffecthasnowbecomeabigproblem.大氣中的溫室氣體，如甲烷和二氧化碳，會吸收一些熱量，使地球氣候保持溫暖和適宜居住。沒有這個過程，地球就無法維持生命。然而，“人為”溫室效應(yīng)現(xiàn)在已經(jīng)成為一個大問題。Whenpeopleproducehugeamountsof(大量的)extra(額外的)greenhousegasesbyburningfossilfuels(化石燃料),moreheatenergyistrappedintheatmosphereandcausesEarth’ssurfacetemperaturetorisequickly.當(dāng)人們通過燃燒化石燃料產(chǎn)生大量額外的溫室氣體時，更多的熱量被困在大氣中，導(dǎo)致地球表面溫度迅速上升。Thereisstrong(確鑿的)andcomprehensive(全面的)evidencethat(引導(dǎo)同位語從句,解釋說明evidence的具體內(nèi)容)theriseintemperaturehasledtoanincreaseinextremeweatherandnaturaldisastersworldwide,notonlycausing(導(dǎo)致)seriousdamage,butalsocosting(使損失，喪失)humanlives.Thereisevidencethat...有證據(jù)表明有力且全面的證據(jù)表明，氣溫上升已導(dǎo)致世界范圍內(nèi)極端天氣和自然災(zāi)害的增加，不僅造成嚴(yán)重的破壞，而且還致人喪命。Climatescientistshavewarnedthatif(that引導(dǎo)的賓語從句本身又是一個主從復(fù)合句，if條件句用現(xiàn)在時表將來)wedonottakeappropriateactions,thiswarmingtrend(變暖的趨勢)willprobablycontinueandtherewillbeahigherpricetopay.Infact,newsreportsarefrequentlybroadcastaboutextremerainstorms(極端暴風(fēng)雨)andheatwaves(熱浪)
