不定式的完成时，表示先于谓语动词发生的动作2013年，一张在挪威北极地区的斯瓦尔巴群岛上发现了一只北极熊尸体的新闻照片让很多人震惊。根据发现这只北极熊尸体的科学家的说法，这只北极熊只剩下“皮包骨头”了。一位研究北极熊多年的专家说，从它尸体的位置看，这只熊似乎是饿死的。Expertsclaimed(专家称,claimtodo宣称做)thatlowsea-icelevelscausedbyclimatechange(过去分词短语做后置定语)meantthebearcouldnothuntseals(捕食海豹)asbefore,soithadtotravelgreaterdistancesinordertofindfood.Thisalarmingcase(惊恐的案例)showedhowtheincreaseintemperaturehadanimpacton(对...有影响,influence,effect)Earth’secology(生态).专家称，由于气候变化造成的海冰水位较低，这只熊无法像以前那样捕猎海豹，所以他为了找到食物不得不去更远的地方。这一令人震惊的案例表明气温升高对地球生态产生了怎样的影响。Thenwhatiscausingtheincreaseintheglobalaveragesurfacetemperature(平均地表温度)?Climatescientistsoftenmentionakey(关键的)climateprocesscalledthe“greenhouseeffect”(过去分词短语做后置定语),which(引导非限定)hastwocommonmeanings:the“natural”greenhouseeffectandthe“man-made”greenhouseeffect.那么是什么正在导致全球表面平均温度的上升呢？

气候科学家经常提到一个被称为“温室效应”的关键气候过程，它有两个普遍的含义：“自然”温室效应和“人为”温室效应。The“natural”greenhouseeffectreferstothefactthat(引导同位语从句,解释说明fact的具体内容)heatfromthesunenterstheatmosphereandwarmsEarth’ssurfaceasshort-waveradiation(短波辐射).

Theheatisreleased(释放)backintospaceatlongerwavelengths(波长).“自然”温室效应指的是来自太阳的热量进入大气层，并以短波辐射的形式使地球表面升温。热量以更长的波长释放回太空。Greenhousegasesintheatmosphere,suchasmethane(甲烷，沼气)andcarbondioxide(二氧化碳),trapsomeoftheheat(困住/吸收热量),keeping(现在分词短语做结果状语)Earth’sclimatewarmandhabitable(适宜居住).Withoutthisprocess,Earthcouldnotsustain(维系)life.However,the“man-made”greenhouseeffecthasnowbecomeabigproblem.大气中的温室气体，如甲烷和二氧化碳，会吸收一些热量，使地球气候保持温暖和适宜居住。没有这个过程，地球就无法维持生命。然而，“人为”温室效应现在已经成为一个大问题。Whenpeopleproducehugeamountsof(大量的)extra(额外的)greenhousegasesbyburningfossilfuels(化石燃料),moreheatenergyistrappedintheatmosphereandcausesEarth’ssurfacetemperaturetorisequickly.当人们通过燃烧化石燃料产生大量额外的温室气体时，更多的热量被困在大气中，导致地球表面温度迅速上升。Thereisstrong(确凿的)andcomprehensive(全面的)evidencethat(引导同位语从句,解释说明evidence的具体内容)theriseintemperaturehasledtoanincreaseinextremeweatherandnaturaldisastersworldwide,notonlycausing(导致)seriousdamage,butalsocosting(使损失，丧失)humanlives.Thereisevidencethat...有证据表明有力且全面的证据表明，气温上升已导致世界范围内极端天气和自然灾害的增加，不仅造成严重的破坏，而且还致人丧命。Climatescientistshavewarnedthatif(that引导的宾语从句本身又是一个主从复合句，if条件句用现在时表将来)wedonottakeappropriateactions,thiswarmingtrend(变暖的趋势)willprobablycontinueandtherewillbeahigherpricetopay.Infact,newsreportsarefrequentlybroadcastaboutextremerainstorms(极端暴风雨)andheatwaves(热浪)
