当天空再次变得湛蓝，河水变得清洁，我们会过上更健康、更快乐的生活。Let’skeepthewordsinmind:ecologicalstarvedcomprehensivebroadcastsseizereleasedfuelstrendpoliciesrestrictsustainableLanguagePointsWehaveknownaboutclimatechangefordecades.ThereislittledoubtthatEarthisgettingwarmerandwarmer(seethegraph).Awarmingoceanandatmospherealongwithmeltingiceandrisingsealevelsprovideevidenceofadramaticchangeintheglobalclimate.我们了解气候变化已有数十年之久了。毫无疑问，地球正变得越来越温暖（如图）。海洋和大气变暖，以及冰层融化、海平面上升，都为全球气候急剧变化提供了依据.LanguagePointsThereislittle/nodoubtthat...毫无疑问...本句是复合句。Thereislittle/nodoubtthat...“毫无疑问...”，that引导同位语从句，解释说明doubt的具体内容。Thereislittledoubtabout/whether...对/对是否...有些疑问。Idoubtwhether/if...我怀疑是否...Idon’tdoubtthat...我确信...alongwith与...一起In2013,alotofpeoplewereshockedbyanewsphotoofadeadpolarbearthatwasfoundonNorway'sArcticislandofSvalbard.Accordingtothescientistswhofounditsdeadbody,allthatremainedofthepolarbearwas"skinandbones".Anexpertwhohasstudiedpolarbearsformanyyearssaidthatfromthepositionofitsdeadbody,thebearappearedtohavestarvedanddied.2013年，在挪威的北极圈斯瓦尔巴群岛的一个岛上，（人们）发现了一只死亡的北极熊，这张新闻图片令许多人感到震惊。据发现北极熊尸体的科学家说，这只北极熊仅剩"皮包骨"。一位长期研究北极熊的专家说，从尸体的姿势看，这只北极熊像是饿死的。Expertsclaimed
