3.cD【解析】木题考查工艺流分析。硫铁矿焙烧取后的烧渣(主要成分为Fe2O3、SO2、AO,不考虑其他杂质)中加入足量酸,欲制釜的产物为FeO4·7H2O,则加入的酸应为硫酸,Fe2O3、ALO3与硫酸反应生成硫酸铁、硫酸锠,二氧化硅不反应,过滤,体1为二氧化硅;在滤液中加入铁粉将铁离子还原为亚铁离子调节p使铝离子完全生成氢氧化铝沉淀过滤,固体2为氢氧化铝,容液2为含硫酸亚铁的溶液,蒸发浓缩、冷却结晶、过滤,得到硫酸亚铁晶体,以此进行解答。由流程分析可知,溶解烧渣选足量硫酸,试剂X为铁粉,故A正确;白流程分析可知,固体1中定含有SO2,调节pH使铝离子完全生成氢氧化铝沉淀,体2为氢氧化铝,故B正确:业铁离子易被空气口的氧气氧化,斤以从溶液2得到FSO4·7H2O产品的过程中不能在空气中进行,故C销误;在溶液中含有铁离子和铝离子,加过量的氢氧化钠溶液铝烹子转化为偏铝悛根离子,钦离子与氢氧根离子结合生成氢氧化铁沉淀,最终得到的是硫酸铁皛体布不是硫酸亚铁贔体,故D错误

第二节【语篇类型】记叙文【主题语境】人与自我—个人经历【文章大意】2岁时,作者告诉身边的人她要成为下一个迈克尔乔丹,于是作者的父亲在她6岁时和她签署了一份合同,约定作者练习篮球要满10000个小时,最终作者在15岁时实现了这个目标。【核心素养】语篇向考生传递坚持的重要性,教导考生要信守诺言、坚持不懈,同时文章凸显"体育",引导考生重视体育锻炼,养成运动的好习惯。【写作指导】 Paragraph1的开头是"那晚,我们开了一个派对有一个巨大的篮球形状的蛋糕″,由此可推断,夲段应该描绘派对上的情形。结合文章信息可知,这个派对是为了庆祝作者实现目标而举办的,所以本段可能会涉及家人及朋友对作者的祝贺;再根据 Paragraph2的开头可知,派对上作者的父亲拿出了作者当初签署的合同,所以本段还应该涉及对该情景的描写以及作者看到合同时的感受根据 Paragraph2的开头"我和父亲把纸放在蜡烛的火焰上,看着它幔慢燃烧"可知,作者完成了当初约定的目标,所以她和父亲烧掉了合同,由此可推断,本段应该描述合同被烧掉后,派对中家人和朋友的反应,以及作者今后的打算。One possible versionParagraph 1That enening we had a party, with a huge basketball-shaped cake.
