可爱）中，"Thecat"是主语，因为它被描述为可爱。主语是句子的核心成分，决定了句子的主被动关系。在英语句子中，主语可以由名词、代词、数词、动名词、不定式甚至整个从句充当。5.参考答案："However"isaconjunctiveadverbusedtointroduceacontrastorconcessioninwriting.Itisusuallyfollowedbyacommaafterthefirstclause.Forexample,"Iwantedtogototheparty,however,Iwastootired."Itcanalsobeusedatthebeginningofasentencetointroduceacontrastingidea.Theword"however"ismoreformalthan"but"andisoftenusedinacademicorformalwriting.解析：本题考查"however"的用法。However是连接副词，用于写作中引入转折或让步关系。它通常在第一分句后跟逗号。例如"Iwantedtogototheparty,however,Iwastootired"（我想去参加派对，但是我很累）。它也可以放在句首引入转折观点。与"but"相比，"however"更正式，常用于学术或正式写作。在正式文体中，当表示转折时，"however"通常比"but"更受青睐，因为"but"更口语化。6.参考答案：Photosynthesisistheprocessbywhichplantsusesunlighttoconvertcarbondioxideandwaterintoglucose(sugar)andoxygen.Itoccursinthechloroplastsofplantcells,whichcontainthegreenpigmentchlorophyll.Theprocesscanbesummarizedbytheequation:6CO₂+6H₂O+lightenergy→C₆H₁₂O₆+6O₂.Photosynthesishastwomainstages:thelight-dependentreactionsandthelight-independentreactions(Calvincycle).解析：本题考查光合作用的过程。光合作用是植物利用阳光将二氧化碳和水转化为葡萄糖和氧气的过程，发生在植物细胞的叶绿体中，叶绿体含有绿色色素叶绿素。这个过程可以用方程式表示：6CO₂+6H₂O+光能→C₆H₁₂O₆+6O₂。光合作用包括两个主要阶段：光反应和暗反应（卡尔文循环）。在光反应中，光能被叶绿素吸收，水分解产生氧气和电子，ATP和NADPH被合成。在暗反应中，ATP和NADPH用于将二氧化碳固定为葡萄糖。7.参考答案：Theareaofatrianglecanbecalculatedusingtheformula:Area=(base×height)/2.Thebaseisanysideofthetriangle,andtheheightistheperpendiculardistancefromthebasetotheoppositevertex.Forexample,ifthebaseofatriangleis10cmandtheheightis5cm,theareawouldbe(10×5)/2=25squarecm.Thisformulaworksforalltypesoftriangles,includingrighttriangles,equilateraltriangles,andisoscelestriangles.解析：本题考查三角形面积的计算方法。三角形面积的计算公式为：面积=(底×高)/2。底可以是三角形的任意一边，高是从底到对顶点的垂直距离。例如，如果一个三角形的底是10厘米，高是5厘米，那么它的面积就是(10×5)/2=25平方厘米。这个公式适用于所有类型的三角形，包括直角三角形、等边三角形和等腰三角形。在计算时，需要确保底和高的单位一致，所得面积的单位是底和高的单位的平方。8.参考答案：Pollutioninurbanareasismainlycausedbyindustrialemissions,vehicleexhaust,constructionactivities,andwastedisposal.Industrialemissionsreleasepollutantslikesulfurdioxideandnitrogenoxidesintotheair.Vehicleexhaustcontainsharmfulgasessuchascarbonmonoxideandnitrogenoxides.Constructionactivitiesgeneratedustandnoisepollutio
