名词。关系代词包括“who”（指人）、“whom”（指人）、“whose”（指人或物）、“which”（指物）和“that”（指人或物）。例如，“ThebookthatIreadisinteresting.”表示“我读的那本书很有趣”。4.参考答案：Photosynthesisistheprocessbywhichplantsconvertlightenergyintochemicalenergy.Itoccursinthechloroplastsofplantcells.Theprocessinvolvestwomainstages:thelight-dependentreactionsandthelight-independentreactions(Calvincycle).Duringthelight-dependentreactions,lightenergyiscapturedandusedtoproduceATPandNADPH.IntheCalvincycle,ATPandNADPHareusedtoconvertcarbondioxideintoglucose.解析：本题考查光合作用的过程。光合作用是植物将光能转化为化学能的过程，发生在植物细胞的叶绿体中。这个过程包括两个主要阶段：光反应和暗反应（卡尔文循环）。在光反应中，光能被捕获并用于产生ATP和NADPH。在卡尔文循环中，ATP和NADPH被用于将二氧化碳转化为葡萄糖。5.参考答案：Theprimarycausesofclimatechangearegreenhousegasemissions,deforestation,andindustrialactivities.Greenhousegaseslikecarbondioxide(CO2),methane(CH4),andnitrousoxide(N2O)trapheatintheatmosphere,leadingtoglobalwarming.DeforestationreducestheEarth'scapacitytoabsorbCO2,exacerbatingtheproblem.Industrialactivitiesreleaselargeamountsofpollutantsandgreenhousegases.解析：本题考查气候变化的主要原因。气候变化的主要原因是温室气体排放、森林砍伐和工业活动。温室气体如二氧化碳（CO2）、甲烷（CH4）和氧化亚氮（N2O）在大气中捕获热量，导致全球变暖。森林砍伐减少了地球吸收CO2的能力，加剧了这个问题。工业活动释放大量污染物和温室气体。6.参考答案：Thestructureoftheatomcontributestoitschemicalpropertiesthroughthearrangementofprotons,neutrons,andelectrons.Thenumberofprotonsinthenucleusdeterminestheatomicnumberandtheelement'sidentity.Thearrangementofelectronsintheelectronshellsdeterminestheatom'sreactivityandbondingbehavior.Forexample,atomswithafullouterelectronshellarelessreactive,whileatomswithoneortwoelectronsintheoutershellaremorereactive.解析：本题考查原子结构与其化学性质的关系。原子的结构通过质子、中子和电子的排列决定其化学性质。原子核中的质子数决定了原子序数和元素的身份。电子在电子壳中的排列决定了原子的反应性和成键行为。例如，外层电子壳满的原子反应性较低，而外层电子壳有一或两个电子的原子反应性较高。7.参考答案：Waterconservationisimportantformaintainingecologicalbalancebecausewaterisessentialforalllivingorganisms.Itplaysacrucialroleinecosystems,suppo
