备战2024年高考化学【一轮·夯基提能】复习精讲精练第13讲陌生情境下氧化还原反应方程式的书写本讲复习目标1、掌握陌生氧化还原反应方程式的书写方法及技巧。
夯基·知识精讲书写复杂氧化还原反应方程式的步骤(1)“读”取题目中的有效信息,找出发生氧化还原反应的物质或离子。
(2)依据掌握的氧化还原反应规律合理地预测产物(这里要重视题目中的信息提示,或给出的生成物),写出主要反应物和生成物的化学式。
(3)根据氧化还原反应的守恒规律确定氧化剂、还原剂、还原产物、氧化产物的相应计量数。
(4)根据原子守恒和溶液的酸碱性,通过在反应方程式的两端添加H+、OH-或H2O的形式使方程式的两端的电荷守恒。
(5)再依据质量守恒,写出规范的方程式。
1.明确一些特殊物质中元素的化合价CuFeS2:Cu为+2,Fe为+2,S为-2;K2FeO4:Fe为+6;FePO4:Fe为+3;LiFePO4:Fe为+2;Li2NH、LiNH2、AlN:N为-3;N2H4:N为-2;Na2S2O3:S为+2;C2O2-4:C为+3;HCN:C为+2;N为-3;CuH:Cu为+1,H为-1;BH-4:B为+3、H为-1;FeO n-4:Fe为+(8-n);Si3N4:Si为+4,N为-3;MnO(OH):Mn为+3;2.认识并掌握常见的氧化剂、还原剂。
(1)强氧化性物质或离子:Na2O2、Fe3+、NO2、HNO3(浓)、HNO3(稀)、O2、O3、H2O2、H2SO4(浓)、Cl2、Br2、HClO、NaClO、Ca(ClO)2、KMnO4(H+)。
(2)强还原性物质或离子:Fe2+、Fe(OH)2、SO2(H2SO3、Na2SO3、NaHSO3、SO2-3)、H2S(Na2S、NaHS、S2-)、HI(NaI、I-)等。
3.书写关键——识记常见氧化剂、还原剂及产物预测(1)常见的氧化剂及还原产物预测(2)常见的还原剂及氧化产物预测4.熟记各氧化反应和还原反应得失电子数目【例题1】MnO2是重要的化工原料,由软锰矿制备MnO2的一种工艺流程如图:溶出时,Fe的氧化过程及得到Mn2+的主要途径如图所示:Fe Fe2+Fe3+MnO2Mn2+步骤II是从软锰矿中溶出Mn2+的主要反应,反应的离子方程式是__________________________。

高中英语学业水平考试必备考点归纳与测试:专题13 单项选择(知识梳理+考点精讲精练)(原卷版)
专题13 单项选择养成良好的答题习惯,是决定高考英语成败的决定性因素之一。
做题前,要认真阅读题目要求、题干和选项,并对答案内容作出合理预测;答题时,切忌跟着感觉走,最好按照题目序号来做,不会的或存在疑问的,要做好标记,要善于发现,找到题目的题眼所在,规范答题,书写工整;答题完毕时,要认真检查,查漏补缺,纠正错误。
1、英语语法知识;(但是在语言逻辑统领下的语法知识考查,而非纯语法。
因此,谁要是单纯从语法角度入手,那么就会正中人下怀。
)2、对近义词、易混词或习惯用语的辨析考查;3、常见词(组),考查一词多义、一词多组的认知与理解;4、动词短语及物与不及物的辨析考查;5、主动语态与被动语态,以及夹杂主谓一致的考查;6、小句子结构的非谓语考查;7、特殊句式的考查;8、各种从句辨析考查;9、情态动词的语气考查;10、句子为单位的小语篇认知;(句子结构要有数的!)11、日常交际用语。
1. 动词的时态和语态(1)选项中有主动、被动,答案往往选被动;(2)选择had done,要找到过去的过去;(3)一定要从句中确定时间,结合翻译去选择答案;(4)选择现在完成时,往往都有标志词,一般都可以翻译成“已经……”;(5)动词的时态语态经常和主谓一致一起考查,with, along with, together with, as well as,rather than, but, except是“就远原则”。
2. 非谓语动词(1)作为正确选项的答案,往往只有to do, doing, done, having done,to be done;(2)一个逗号后面,往往选doing,逗号后一般不选to do。
(3)only to do表意外结果或事与愿违的结果;(4)逻辑主语一般是句子主语或挖空左边的名词,结合翻译确定;(5)选项中有doing也有having done需要重点看看有没有动作先后顺序;(6)to be done翻译成“将被”,being done翻译成“正在被”;(7)having done 不是被动,它的被动是having been done;(8)非谓语动词能做主语的只有动名词和不定式;(9)每年高考考两题,这两道题的考点一般都是不一样的。

情景交际说课稿
各位老师你们好!今天我要位大家讲的课题是情景交际。
它是英语中以对话为主要表达形式,以情景为条件的对话口语形式。
考查学生在真实的交际中,能运用正确的英语,得体地表达自己的意图,完成交际,首先,我对本节教材进行一些分析:一,教材分析(说教材)1.教材所处地位和作用情景交际是学生开始接触英语就已经以对话的形式出现了,而且它在以后的英语学习中一直贯穿始终。
是近几年来中考的热点题目,在全国各地中考英语试卷中约占笔试分值的10%-15%。
近几年来全国很多省市以单项选择的形式考查了情景交际,内容全面。
选项型和填空型补全对话贴近生活。
学情分析:中学生的思维发展能力较强,善于运用形象思维能力,表现欲减弱,这就要求学生上课时提高注意力,注意中西方的文化差异,提高他们的学习兴趣,,达到根据上下文能做出合理判断的能力。
2.教育教学目标:根据上述教材分析,考虑到学生已有的认知结构和心理特征,制定如下教学目标:(1)知识目标:通过教学让学生掌握各种句型的结构,能够根据上句来回答下句,根据下句推测上句。
(1)能力目标:通过教学初步培养学生分析问题,解决实际问题,读图分析,收集处理信息,初步培养学生运用知识的能力,培养学生加强理论联系实际的能力(2)情感目标:通过情景交际的教学引导学生从现实的生活经历与体验出发,激发学生学习兴趣。
3.重点,难点及确定依据:重点:根据情景联系上下文,作出合理准确的判断,使对话语句通顺,意义连贯。
重点主要是进行问候,自我介绍,介绍他人,还有发出邀请,接受邀请,拒绝邀请时的习惯用语及固定搭配,约会时询问有无空闲时间,提出约会时时间,地点,征求对方的意见,难点:能正确把握对话大意,排除干扰项。
主要是打电话时中英文表达习惯的不同,购物时常用的句式和短语。
关键:要先通读,根据日常习惯,注意中英文差异,积累英语国家背景知识。
下面,为了讲清重难点,使学生达到本节课设定的目标,再从教法和学法上谈谈:二,教学策略(说教法)1.教学方法及其理论依据:坚持以‘学生为主体,以教师为主导’的原则,根据学生的心理发展规律,采用学生参与程度高的学导式讨论教学法。
初中情景交际教案
初中情景交际教案一、教学目标:1. 让学生掌握购物场景中常用的交际用语,如询问价格、挑选商品、付款等。
2. 培养学生能够在购物场景中运用所学知识进行实际交流的能力。
3. 提高学生对英语口语表达的兴趣,增强自信心。
二、教学内容:1. 购物场景中常用的交际用语。

鼓励学生运用所学知识进行实际交流。
4. 角色扮演:学生两人一组,一人扮演顾客,一人扮演店员,进行角色扮演练习。
教师巡回指导,纠正发音,给出建议。
5. 小组竞赛:教师设立一个小竞赛,看哪个小组能够在购物场景中运用所学知识进行最流利、最自然的交流。
6. 总结与反思:教师引导学生总结所学内容,让学生谈谈自己在实践中的收获和不足,鼓励学生继续努力。
四、教学评价:1. 观察学生在购物场景中的交际表现,评价学生对购物场景常用交际用语的掌握程度。
2. 学生之间的互相评价,鼓励学生互相学习,共同进步。
3. 教师根据学生的表现给予鼓励和指导,帮助学生提高英语口语表达能力。
五、教学建议:1. 教师应注重培养学生的口语表达能力,鼓励学生大胆开口。
2. 增加情景模拟的环节,让学生在实际场景中运用所学知识。
3. 教师应关注学生的个体差异,因材施教,给予每个学生充分的关注和指导。
4. 鼓励学生在课后进行购物实践,将所学知识运用到实际生活中。
通过本节课的教学,希望学生能够在购物场景中熟练运用所学知识,提高英语口语表达能力,增强对英语学习的兴趣和自信心。

【2016考纲解读】交际用语的考查点相对集中。
主要考查社会交往中的一些日常交际用语。
考查的方式以应答为主,提问为辅;以跨文化交际中差异明显的交际项目为重点考查对象。
其考点主要包括:1.考查习惯应答语。
许多情景对话中使用的是英美人的习惯用语。
问候、告别、打电话、问路、看病、购物等常见的交际话题均有其较为固定的套语;感谢、道歉、祝愿、请求亦有其固定的应答用语。
考生必须用英美人的思维方式,遵循他们的习惯进行回答。
交际用语常见的回答用语主要有以下几个方面:(1)常用于接受或拒绝请求、邀请的应答用语有:With pleasure./Yes, help yourself./No problem./Good idea./Sorry, but…/I‘d rather you…/Thank you, but…/No way./Forget it.等。
(2)常用于感谢的应答用语有:That‘s all right./You are welcome./Don’t mention it./It is my pleasure (My pleasure)./Not at all.等。
(3)常用于道歉的应答用语有:Nev er mind./It doesn‘t matter./Not at all./That’s all right./That is nothing.等。
(4)常用于祝愿和祝贺的应答用语有:Good luck!/Best wishes to you!/Have a nice time!/Congratulations!/Merry Christmas!/Thank you!/The same to you!等。
2.考查文化差异语。
汉语和英语在交际文化方面有许多共同之处,但也存在诸多差异。
这些差异往往是考查的重中之重。
避免母语交际定式的干扰,根据英语的文化交际习惯来应答是掌握文化差异的关键。
3.考查语言结构语。
根据不同的交际情景,说话者会采用不同的交际用语来表达自己的态度和情感。
当说话人对刚刚提出的说法或意见持肯定态度时,可以说:Yes,I think(suppose,believe)so./Yes,I‘m afraid so. 对刚刚提出的说法或意见持否定态度时,则说: No,I don't think (suppose) so./No,I don't believe so./ No,I believe (suppose) not./No,I hope not./ No,I am afraid not.【重点知识梳理】情景交际用语指在特定的语境中运用的语言。
情景交际用语范围广泛,形式多样,灵活多变,这些情景交际语言的结构无不体现着英语国家的文化、风俗和习惯。
情景交际用语的功能主要包括四十一个项目。
