篇2：中考语文复习教案2

中考语文复习教案（2）

第三、四课时汉字一、考点分析《语文教学大纲》和《语文课程标准》中规定中学生应该能够掌握3500个左右常用字。在中考考试中，查考汉字，主要是为了准确区分常见的同音字，能够辨析简单的形似字，能够理解常见多音多义字在不同词语中的读音和意义，同时要要求同学们书写汉字笔画清楚，字形正确、规范。从近几年的中考来看，汉字考查一般放在语音考查的后面，或者与语音题结合在一起，试题分值往往二到四分。有的采用选择的形式，有的采用让同学们根据拼音书写汉字的形式。考查的内容都是在教材中出现，常用常见又易错的词语。此外，同学们还应该了解汉字构造，掌握常见字的笔顺、笔画、辨析形声字的声旁和形旁，熟练使用汉语工具书，学会部首和音序检字法。对于汉字的考查，不局限于选择题或者填空题，在阅读题中，也常常考查同学们对于汉字的理解。二、备考指南同学们在复习的时候，应该以教材为基础，逐课进行汉字的积累。把每一课中出现的重点字词都罗列出来。对于多音多义字，应该能够根据具体的语境，辨析汉字的准确读音和意义。对于形似字，要注意运用比较的方法，辨析他们的区别。（一）纠正、防止错别字的方法 1．分辨形旁，注意字音。如贝多和财物有关，亻多和人有关，饣多和饮食有关；纟多和丝、棉、麻有关，氵多和水有关；衤多和衣服有关；月多和身体有关。 2.看清声旁，分辨同音字，如沧不要写成沦，经常不要写成经长。 3．分辨形似字意义，如菅和管；分辨同音字意义，如抱负与报复。 4．记住少数带多数。辶和廴，从廴的字只有三个：廷、建、延，其余均从辶。 5．不随意简化（二）笔画和笔顺在书写汉字时，从落笔到抬笔，就是一笔或叫一画，这些点或画就叫笔画。汉字基本笔画有八种，即：点、横、竖、撇、捺、勾、折、提。每一种笔画有一种或几种变形写法。写字时笔画的先后顺序，叫笔顺。常见的笔顺规则有以下八种：先左后右，如认、助、则、仁等；先上后下，如王、旦、恩、梦等；先横后竖，如十、干、主、井等；先撇后捺，如人、文、令、义等；从外到内，如同、月、闻、风等；先进后关，如园、田、因、国等；先中间，后两边，如小、水、办、少等；先里头，后旁包，如断、画、函等。学习掌握汉字笔画和笔顺规则，有助于我们正确查检字典、词典，指导书写，还能使写出的字体工整美观，提高书写速度。（三）形声字形声字由两部分组成，一部分表示字的意义，另一部分表示字的读音。表示字义的部分叫形旁，表示字音的部分叫声旁。形旁和声旁结合方式主要有六种。左形右声：偏铜冻征硝城右形左声：攻劲削瓢故雌上形下声：管霜爸芳崖界下形上声：慈斧贡忿凳膏外形内声：固病阀园裹衷内形外声：闻问闷辩（四）形似字、同音字、多音多义字有些字形体相近，不细心分辨就容易写错、用错。例如，未来的未和末梢的末，区别仅仅在起笔两横的长短，意思却完全不同。正确书写和运用形似字，主要靠认真。把字形认准，字义弄懂，一笔一画认真书写。还要在积累词汇的同时，分辨形似字。有些字读音相同，这类字叫同音字，例如，唤换涣焕都读huàn，壁和璧都读bì。还有些字读音相近，如浊（zhuó）和烛（zhú）。分辨读音相同或相近的字，要从字义入手，并且记住经常和什么字组成词使用。不止一个读音，不止一个意义的字叫多音多义字。分辨这类字也要从字义入手，记住读这个音时表示什么意思，读另一个音又表示什么意思。例如：薄，用在薄板中读báo，表示厚度；用在薄弱中读bó，表示单薄、弱；用在薄荷中读bò，是一种植物的名称。（五）查字典 1．音序检字法如果知道某个字的读音，想查这个字的意义，就可以使用音序检字法。例如查津字的意义。知道津读jīn，按这个音节的声母j去查汉语拼音音节索引，知道属于jīn的音节的字在哪一页，然后再找到这一页，就查到津字了。 2．部首检字法如果不知道某一个字的读音，就可以使用部首检字法。例如查津字，首先确定要查的这个字属于氵部，然后从部首目录中找到氵部在检字表中的哪一页，再从检字表查出津字在字典的哪一页。注意：在检字表中查津字的笔画，只查除去部首部分的笔画，即只查聿的笔画--6笔。 3．常用符号的意义一个字因意义不同而有几个音的，就在各个注音前用（一）（二）（三）等标明。一个字不止一个意义的，就用①②③等表示有几个意义。注解中的引、喻、转、连等符号，引表示由原意引申出来的意义，喻表示由比喻形成的意义，转表示由原义转化而成的意义，连表示本字可以和一个意义相同或相近的字并列起来构成大致同义的词。（六）正确识记汉字的字形，应注意以下几点：（1）掌握汉字的字形要靠日积月累，平时读书看报，看电视都要做有心人，遇到不认识的或拿不准的字，一定不要随便放过，要勤查字典，积累多了，出错也就少了。（2）要将汉字的字形与它的音和义结合起来识记，这样比死记硬背掌握要轻松得多，记得也要牢固。第一，要了解汉字的基本特点。音形义统一是汉字的基本特点。要从三者的对应关系入手，根据现代汉字的字音和字义，正确识别它的字形。第二，要了解现代汉字的结构特点，现代汉字据85%以上是形声字，一般来说，声旁表音，形旁表意，因此可以通过形旁加以辨别。第三，要了解错别字产生的`原因：①音同或音近造成错误。②形近造成错误。③音近形近造成误读。④不明成语典故造成错误。第四，要掌握识别错别字的方法，了解了错别字产生的原因，就可以通过读音，字形及其意义去识别了。近几年中考的语音、汉字题，更多地着眼于实际运用，更加贴近生活。如在具体语境中给汉字注音，根据拼音写出汉字，改正错别字。材料多取材于报刊、杂志，在实践中考查学生语音、汉字的语言知识。第五、六课时词语（成语）及运用一、考点分析近几年中考试题中，对于词语的考查，主要偏重于理解词语在具体语言环境中的意义，分辨词语在具体语言环境中的感情色彩，并能能够根据语言环境正确使用词语。中考中所考查的词语，往往是两音节的或者是成语。分值往往在四到六分。对于词语的考查，可以在语文基础知识中进行，也可以在阅读中进行。词语是我们学好语文的基础。在写作当中，我们同样会用到词语。词语掌握的好坏，也直接关系到作文水平的高低。二、备考指南对于词语的识记，同学们要尽可能地在理解课文的基础上，来揣摩和理解词语的意义。同学们应该总结教材中每一篇课文中出现的重点词语。要复习词语的时候，要注意以下几个方面的内容。三、复习要点 1、掌握课文中常用词语的书写； 2、理解重要词语在具体语境中的含义，并能根据语境进行揣摩，理解词语的比喻义、引申义； 3、能根据语境需要正确选用词语，并能根据语境辨析词语（或成语）运用的正误； 4、能根据语境准确、得体、连贯运用词语（或成语）； 5、能根据语境正确运用关联词。（一）正确理解词义词有单义和多义之分。单义词大多是表示事物名称的词、科学术语、外来词和新造词。汉语中大量的词是多义词。凡是表示多种相互联系的不同意义的词叫多义词。一个多义词不论它的义项有多少个，其中必有一个是本义，其它的意义是从这个本义发展变化而来。意义发展变化的途径有两种：引申和比喻。引申义是由词的本义演变发展而产生的意义，因此引申义与本义在意义上或多或少有一种“子与母”、“流与源”的关系。如“浅”的本义是表示从表面到底部距离短的意思（水很浅）。引申为程度不深（他的功底浅）；引申为表示时间不久（他们相处的日子很浅）；引申为颜色淡（浅蓝色）。学习过程中要记住本义，学会引申。比喻义是通过基本义的比喻用法而逐步固定下来的新义。如用“手足”比喻“兄弟”，用“虎口”比喻危险境地。词的比喻义和修辞上的比喻不同。词的比喻义虽然最初是通过比喻用法逐渐形成的，但它已经成为词的一个新的固定意义，为群众所接受；而比喻修辞是在特定的语言环境中临时打比方；本体和喻体间无固定搭配关系，一个本体可以有多个喻体。了解了汉语的词义特点，同学们在考试中要结合语境对词语的含义进行具体分析。（二）词语的感情色彩类型概念举例褒义词带有赞许、肯定、喜爱、尊敬等感情色彩的词秀壮丽谦逊刚强贬义词带有贬斥、否定、厌恶、鄙视等感情色彩的词笨奸诈卑劣渺小中性词不带褒贬感情色彩的词状况配合方法（三）辨析近义词： 1．从意义方面来辨析词义的轻重不同：如“激动”比“感动”更急剧，更强烈。词义着重点不同：如“诡辩”着重在“诡”，即欺诈、怪异，“诡辩”就是用欺诈的手段、奇怪的言辞来为自己的谬论辩护。“狡辩”着重在“狡”，即不老实、耍花招，“狡猾”就是歪曲事实，狡猾的为自己的错误言行辩解。词的范围大小不同：如“战争”、“战役”和“战斗”范围由大到小。 2．从色彩方面来辨析感情色彩不同：如“爱护”是褒义词，“庇护”是贬义词。语体色彩不同：如“出租车”适用于书面语，“的士”适用于口语。 3．从用法方面来辨析搭配对象不同：如“爱戴”适用于对长辈、上级，“爱护”适用于对晚辈、下属。语法功能不同：如“公然”在句中只能作状语，如“公然侵入”，“公开”在句中还可以作谓语和定语，如“事件的真相早已公开了”，“公开的秘密”。（四）正确使用成语考题中常见的成语使用的错误现象主要有以下几种： 1．望文生义。如“告别时，这位服装个体户一定要送我几件高档的衣服，

三、精典名题导解

题1（NMET ）

_________production up by 60%,the company has had another excellent year.

A.As B.For C.With D.Though

分析：C. production 之后为up,它是一个副词，for不能位于句首且常引导原因状语从句。A、D不适于“介词＋宾语＋宾补”这一结构。

题2（NMET ）

I would love_____________to the party last night.But I had to work extra hours to fnish report.

A.to go B.To have gone

C.going D.having gone

题3（上海）

She can’t help___________the house because she’s busy making a cake.

A.to clean B.cleaning

C.cleaned D.being cleaned

分析：A.此题的句意是：她不能帮忙打扫房子，因为她忙于做蛋糕。can’t help cleaning是“忍不住要打扫”，与下文矛盾。

题4（NMET 1999）

The purpose of new technologies is to make life easier, _______ it more difficult.

A.not make B.not to make

C.not making D.do not make

分析：B.空白处以后部分与to make life easier为并列成分，因此后面也用不定式。

题5（NMET 1999）

Robert is said___________abroad,but I don’t know what country he studied in.

A.to have studied B.to study

C.to be studying D.learning

分析：A.从studied in可知不定式的动作指过去，应用完成时。

A.looked up B.took for

C.picked out D.picked up

C.Losing D.Because of losing

分析：C.从问句看，问的是made的主语。上述选项中只有动名词可作主语。

A.an underground lake was discovered

B.there was on underground lake discovered

C.a lake was discovered underground

D.the workers discovered an underground lake

分析：D。从句中的building表示主动，其前省去了主语，且与主句的主语一致，A、B、C三个选项中的主语不能发出动作build。

题5（上海 2001春）

______from heart trouble for years,Professor White has to take some medicine with him wherever he goes.

A.Suffered B.Suffering C.Having suffered D.Being suffered

题11（上海 2001）

________is no possibility_______Bob can win the first prize in the match.

A.There;that B.It;that C.There;whether D.It;whether

分析：A。possibity后应引导一个同位语从句，因其前有no修饰，所以其后不用whether。“存在有……”应该用“There is…”。

题12（上海 2001）

What the doctor really doubt is________my mother will recover from the serious disease soon.

A.when B.how C.whether D.why

分析：C。“医生怀疑的是是否康复”。

篇7：名著阅读复习优秀教案

《简·爱》：人生追求的二重奏

《简·爱》是一部自传成分很浓的小说，虽然书中的故事是虚构的，但是女主人公以及其他许多人物的生活、环境，甚至许多生活细节，都是取自作者及其周围人的真实经验。作者夏洛蒂·勃朗特18生于英国北部的一个牧师家庭。母亲早逝，八岁的夏洛蒂被送进一所寄宿学校。在那里生活条件极其恶劣，她的两个姐姐因染上肺病而先后死去。于是夏洛蒂和妹妹艾米利回到家乡，在荒凉的约克郡山区度过了童年。。她曾打算自办学校，为此她在姨母的资助下与艾米利一起去意大利进修法语和德语。然而由于没有人来就读，学校没能办成。但是她在意大利学习的经历激发了她表现自我的强烈愿望，促使她投身于文学创作的道路

《简·爱》写于1846年，是夏洛蒂的第二部小说。她借一个出身寒微的年轻女子奋斗的经历，抒发了自己胸中的积愫，深深打动了当时的读者。小说于1847年秋以柯勒·贝尔的笔名发表，随即在次年又相继两次再版。这位名不见经传的作者，夏洛蒂·勃朗特，由此进入英国著名小说家的行列。

聆听天籁：读读泰戈尔

篇9：名著阅读复习优秀教案

中考名著复习学案

第一课时：考纲题型

一.明确考点：

《语文课程标准》7～9年级“阶段目标”对课外阅读是这样规定的：“学会制订自己的阅读计划，广泛阅读各种类型的读物，课外阅读总量不少于260万字，每学年阅读两三部名著。”

《语文课程标准》指出：“培养学生广泛的阅读兴趣，扩大阅读面，增加阅读量，提倡少做题，多读书，好读书，读好书，读整本的书。”“重在考察能否把握阅读材料的大意。”由此可见，中考名著阅读主要考查学生对整本名著的主要内容的理解和把握。

《语文课程标准》推荐名著篇目：

诗歌散文作品，如鲁迅《朝花夕拾》、冰心《繁星·春水》等。

长篇文学名著，如吴承恩《西游记》、施耐庵《水浒》、老舍《骆驼祥子》、笛福《鲁滨逊漂流记》、斯威夫特《格列佛游记》、罗曼·罗兰《名人传》、高尔基《童年》、奥斯特洛夫斯基《钢铁是怎样炼成的》等。

龙岩市中考信息考查6部文学名著：《西游记》、《水浒传》、《鲁滨逊漂流记》、《格列佛游记》、《钢铁是怎样炼成的》、《伊索寓言》。

二.复习方略：

中考复习时间紧，名著阅读量大。重读名著是不可能的，干脆放弃又太可惜。较好的办法是：整体把握，重点理解，以纲带目，适当练习。

1.记忆名著常识，包括书名、作者及其朝代(国别)等。

2.从整体上把握并理解名著的思想内容和艺术特色。可借助“目录”“前言”“说明”“导读”等内容进行复习。

3.把握重点人物性格特点，理解重点章节、语段，熟悉故事情节、主要人物特点及其人物间的关系等。

4.熟悉名著阅读试题的形式。

三、名著复习提要

寓言类的复习提要：

概括故事内容。

揣摩故事幽默诙谐的语言。

联系自己的生活经验，思索书中的思想精髓，体会蕴含的人生智慧。

领会故事揭示的道理，思考故事给你的启示。

让学生阅读《伊索寓言》故事，根据阅读复习提要回答问题。

例：《掉在井里的狐狸和山羊》写的是掉在井里的狐狸哄骗山羊下井，然后踩着山羊背跳出井底，却扔下山羊不管的故事，警示人们做好事也要看对象，以免上当受骗。

篇10：名著阅读复习优秀教案

《格列佛游记》：奇异的想像，辛辣的讽刺

斯威夫特(1667—1745)，英国著名讽刺小说家和政论家。

主题：《格列佛游记》以其杰出的讽刺而名垂世界文学史。小说通过格列佛在利立浦特(小人国)、布罗卜丁奈格(大人国)、勒皮他(飞岛国)和慧骃国的奇遇，反映了十八世纪前半期英国社会的一些矛盾，揭露批判了英国统治阶级的腐败和罪恶及英国资产阶级在资本主义原始积累时期的疯狂掠夺和残酷剥削。

主要情节及对应寓意：

1、描写小人国利里浦特的党派之争以鞋跟高低划分阵营，“高跟党”和“低跟党”尔虞我诈，争权夺利，实际上是挖苦英国两个争斗不休的政党。讲述小人国利里浦特与邻国兵戎相见，是影射当时英法两国之间的连年征战。

2、在大人国，格列佛洋洋自得的介绍却招来质问，大人国制度古朴、民风淳朴，他们认为英国近百年来的历史充斥着“贪婪、党争、伪善、无信、残暴、愤怒、疯狂、怨恨、嫉妒、淫欲、阴险和野心”及其产生的恶果。

3、小说第三卷，通过对飞岛国等五国的描述，表达了对现代科技的怀疑，并严词痛斥了殖民统治。

4、第四卷更是以恣肆的笔调，展示了人兽颠倒的怪诞现象。在这个乌托邦国度里，马是理性的载体，而人形动物“耶胡”则是邪恶肮脏的畜生。格列佛和慧骃之间的对话成了对“人类”社会的无情鞭笞。

艺术特色：

《格列佛游记》不但具有深刻的思想内容，而且具有比较完美的艺术形式。首先，斯威夫特利用虚构的情节和幻想手法刻画了当时英国的现实。同时他也是根据当时英国的现实才创造出一个丰富多彩的、童话般的幻想世界。斯威夫特的幻想世界是以现实为基础的，而现实的矛盾在幻想世界中则表现得更为集中突出。比如一六八八年英国政变后，托利党和辉格党争权夺利，互相倾轧，而实际上他们都代表贵族和资产阶级的利益。斯威夫特抓住了议会党派斗争的本质特点，创造了小人国的高跟党和低跟党。再如针对英国对爱尔兰的统治和剥削，斯威夫特创造了飞岛上的人与地上的人民之间的斗争。这些虚构的情节就把现实表现得更为强烈、更为集中、更为典型，而且更带普遍性。十八世纪初年的英国虽然距今有二百多年，可是我们今天读了《格列佛游记》，还深深地感到它的许多情节仍有现实意义。《格列佛游记》的讽刺艺术是杰出的，作者的讽刺手法也是多种多样的。在小人国里，万物仅有正常尺度的1/12，格列佛在那有如一座大山。到了大人国，格列佛便成了一个小小的“宠物”。作者借游记，借外人之眼来评议自己的国家。如描写小人国的党派之争以鞋跟高低划分阵营，实际是挖苦英国两党之争;在大人国格列佛洋洋自得向国王介绍英国却遭连串质问;在马国，马是理性的载体，而人形动物“耶胡”则是邪恶肮脏的畜生。他以漫画式的夸张技巧无限扩大了耶胡、勒皮他人和长生不老的人的可恶和怪诞的形象，他还以一本正经的严肃态度、细致逼真的细节描写刻画了小人国的生活和斗争，极为成功地反映出当时英国的现实。斯威夫特还善于用严肃认真的口吻叙述渺小无聊的事情，从而产生了强有力的反讽效果。

阅读感受：

①小说充满了奇异的想像和童话色彩;②辛辣、尖锐而深刻的讽刺是小说的灵魂所在;③小说的讽刺饮包含某些对人性及人类社会的悲观见解，但在尖刻与悲观的态度背后，却隐藏着一种苦涩而热切的忧世情怀。④小说作者借游记、借外人之眼来评议自己国家的现状。

篇11：初三化学总复习优秀教案

初三化学总复习优秀教案

(1) 写出A、B的化学式：A ，B 。

(2) 在物质的分类中，D属于 (填“酸”、“碱”、“盐”或“氧化物”)。

(3) 图中反应②的化学方程式为。

(4) 图中反应④的化学方程式为。

【思路点拨】根据发酵粉获知A是碳酸钠，根据E、F的俗名是熟石灰、纯碱逆推得出C是水，D是二氧化碳。

【方法归纳】一些教材中出现的重要的酸、碱、盐及氧化物要熟悉它们的用途和俗名，这往往是解题的突破口，有些推断题正推不妥就换成逆推，重要的是将物质推完要放回原题验证下整体是否符合逻辑，确保答案正确。

例2．A―D是我们已经学过的四种常见物质，它们都不属于酸和碱，A 是红色固体，它们与稀HCl、Ca(OH)2之间的相互关系如下图所示（“→”表示物质间的转化关系，“ ____ ”表示物质间可以相互反应）。

请回答下列问题：

⑴ 写出物质A、B、C的名称：A 、B 、C ， ⑵写出下列反应的化学方程式：

① ，② ，

⑶ 反应③的基本类型是_____________________。

【思路点拨】先根据题意A―D是我们已经学过的四种常见物质，它们都不属于酸和碱，可推知它们只能是单质、氧化物、盐这三类物质，然后结合物质的颜色，可知A是氧化铁或铜，但酸不能与铜反应，所以A是氧化铁，B只能是铁，右边C、D则根据碱的通性，可推知C是非金属氧化物二氧化碳，D是碳酸钠

【方法归纳】遇到酸的连线图则根据酸的五点通性去推（一般酸与指示剂除外），遇到碱的连线图则根据碱的四点通性去推（碱与指示剂除外），遇到盐为中心的连线图，则想到酸碱盐的通性中有八点可以生成盐的途径。

【课堂练习】

1．（中考题第20题）右下图化学反应的溶液颜色变化体现了“魔法世界，魅力化学”。请回答：

（1）溶液X是______（填“酸”、“碱”、“盐”），试剂A是的名称是_____________。

（2）若X是稀硫酸、B是氧化物，则B的化学式为_____________。

（3）若X是稀盐酸、C是单质，则C的名称为________________。

（4）若X是稀硫酸、D是碱，则X与D反应的化学方程式为______________。

【思路点拨】能与多种物质反应产生不同颜色的一般是酸，结合溶液的.颜色推出各物质

【方法总结】在推断题中，物质或溶液的颜色是判断物质的突破口，关键的节点，争取要熟记

2.（中考题第20题）

有五种化合物，它们两两之间发生的某些转化关系如下图箭头所示。请回答：

（1）Na2SO4→NaCl的转化反应属于反应（填基本反应类型）；这一类型反应能发生必须具备的条件之一是（填一种）。

（2）NaOH→Na2SO4 ；

NaCl→NaNO3 。

（3）在图中的物质间转化关系中有的可以逆向转化。

他们分别是： → ； → （填化学式）。

【思路点拨】碱生成盐往往优先考虑酸碱中和反应，根据盐的组成判断酸的组成，酸、碱、盐之间相互转化要充分考虑到复分解反应的条件。

【方法总结】碱和盐、盐和盐两类的反应要符合两个条件，反应物要可溶，生成物有沉淀。

【布置作业】冲刺第148页12、13、14三题（附题目）

Sentence patterns:

1．强调句型的运用与高考

强调句型常用于书面语，也可用于口语，用来突出说话人要强调的语言信息，给对方以强烈的印象和感受。强调句型是高考范围内的语法内容，更是高考命题者颇为青睐的语法项目之一。下面对该句型的用法作一阐述。

一、句型特征及含义

强调句又称为分裂句。其结构形式为“It ＋be的适当形式＋被强调部分＋that／who ＋其它”。在该句型中，it无词义，且不可用this，that换用；若原句的谓语动词用了现在时或将来时，则be动词用is；若原句的谓语动词用了过去时，则be动词用was。有时为了表达需要，也可在be前加上may／might／must等情态动词；若被强调部分是人，引导词用 who（若强调部分是作宾语的人，则也可用 whom）或that均可；若是其它强调部分，则一律用that。翻译时常加上“正是……；就是……”等字眼，以突出其强调含义。例如：

It is I who am to visit Hangzhou tomorrow．就是我明天要去杭州参观。

．．．for it was in Greece that Olympic competitions firstly started．

（SEFC BIII L34）……因为就是在希腊奥林匹克运动会首次开始举办的。

It must be John that／who will take part in the contest on behalf of our class．

必定是约翰将代表我们班参赛。

It might be at the party that Tom knew her．

可能就是在这次聚会上汤姆认识她的。

二、强调角度及运用

1．强调主语、宾语或状语。例如：

It was John who／that broke the glass yesterday．（强调主语）

It is me who／whom／that you should help．（强调宾语）

It was at the gate that he told me the news．（强调地点状语）

It was with great joy that he received the news that his long lost son would soon return home．（强调程度状语）

It is by bus that Wang Gang often goes to school．（强调方式状语）

It was about 600years ago that the first clock with a face and an hour hand was made．（强调时间状语）

It was in order to catch the first bus that they got up earlier．（强调目的状语）

2．强调状语从句。

（1）强调时间状语从句：

It was only when I reread his poems recently that I began to appreciate their beauty．

（2）强调原因状语从句：

It was because Li Ping was ill that he didn't come to school last week．

（3）强调地点状语从句：

It is where you come from that you should return to it．

（4）强调方式状语从句：

It is as you like that you may do everything．

3．强调含有“not．．．until．．．”结构的句子时，要用

“It is／was not until．．．that．．．”结构。that后的句子要用肯定句，且须用陈述语序。

例如：

It was not until she took off her dark glasses that I recognized she was a famous

film star．

It was not until 1920 that regular radio broadcasts began．

4．强调含有定语从句的主语、宾语或状语。例如：

Was it at the school which was named after a hero that he spent his childhood？

5．强调含有either．．．or．．．，neither．．．nor．．．，

not only．．．but also．．．，as well as，not．．．but．．．等词组所构成的句子。例如：

It was neither you nor he that is willing to go to the Great Wall．

It was he as well as his classmates who has ever been to Suzhou．

三、句型转换及主谓一致

1．变为一般疑问句（把主句中的be动词或情态动词提到句首即可）

Was it during the Second World War that he died？

2．变为特殊疑问句（须用“特殊疑问词＋be或情态动词＋it＋that．．．？”结构）

When could it be that he went to our country？

3．变为否定疑问句（须在主句上进行变化）

Couldn't it be by plane that he went to France？

4．强调句型的反意疑问句（须和主句一致）

It was at eleven last night that I knew the good news，wasn't it？

5．强调句型的主谓一致问题（即使被强调部分是复数含义，主句的谓语动词仍然用单数形式）

It is they who often help me with my lessons．

It was these books that they bought the day before yesterday．

注意：若强调句在整个复合句中作宾语，强调句须用陈述语序。例如：

He told me that it was Li Hua who was standing under the tree reading English．

四、相似句型及异同

1．强调句和主语从句句型（指“It＋ be ＋adj．／n．＋that-clause”类型）的异同点

二者均有It be．．．that／who．．．之类的语言标志。所不同的是：（1）含有主语从句的句子译为汉语时不可加上“正是……”或“就是……”之类的字眼，而强调句则可以。（2）含有主语从句的句子若删掉It be．．．that／who．．．，则原句不论结构还是语意均不成立，而强调句去掉结构标志却仍然成立。例如：

It is true that he once went to Canada．（不可去掉It is及that，否则原句不成立。）

It was on December 11，that China became a member of WTO．（去掉强调结构原句仍然成立。）

2．含有定语从句的强调句型

强调句型中含有定语从句，往往会给学生造成错觉，以致分不清哪一句是强调部分，哪一句是定语从句，尤其是强调句中的定语从句的引导词是that或who时，更容易造成错觉。办法是仔细分析that或who在句中的作用：若that或who可有可无（结合it be来分析），则为强调句，否则是定语从句。例如：

It was in the lab that was set up by Mr．Smith that they finished the experiment．

（lab后的that不可以省略，因为that作该句的主语。句中第二个that才是强调句的标志。）

It was Tang Ling who came from Hunan that won the first prize in the contest．

（who在该句中作主语，所以不可以省略，后面的that才是强调句的标志。）

3．定语从句与强调结构。试比较：

1)It is the house where I met the young man.

(where 引导定语从句，修饰house，where在定语从句中作地点状语)

2)It was in the house that I met the young man.

(本句为强调结构，可还原为I met the young man in the house.)

II.with引导的独立主格结构

英语中，with引导的独立主格结构很富有表现力，在句子中作状语，表示伴随、方式、原因、结果等。它不是句子而是短语，其结构为：with＋名词／代词＋介词短语／形容词／副词＋名词／非谓语动词。现将with引导的独立主格结构作一小结。

A. for B. with C. from D. of

[解析]答案是B。这还是“with +宾语+宾语补足语”结构。

III. so/such/as/ the same as/that的区别。

as 的用法：

例1.the same… as；such…as; as / so…as…中的as 是一种固定结构, 和……一样……。as既可指人，也可指物，常在限制性定语从句中充当主、宾、表语。as引导的定语从句的先行词前面常有as ／such ／the same等修饰词。还要注意区分下列两个词组：

1．“such．．．that．．．”表“如此……以致……”的意思，用来引导一个结果状语从句；而“such．．．as．．．”表“像……这（那）样”的意思，用来引导定语从句，as在定语从句中充当主、宾、表语等。试比较下列两个句子：

①He is such an honest man that we respect him.

他是一个如此诚实的人以致我们都尊敬他。

② He is such an honest man as we respect．他像我们所尊敬的那种诚实的人。

2．“the same．．．that．．．”表同一人或物，而“the same．．．as．．．”表同种类的东西。试比较下列两个句子：①This is the same book that I lost．这就是我丢失的那一本书。（指同一本书）②This is the same book as I lost．我丢失的那一本书一模一样。（并不是原来的那一本）

例如：

He is as brave a man as ever lived．他是世界上最勇敢的人。

Don't read such books as are not worth reading．不要读那些不值得读的书。

I have got into the same trouble as he (has).

The film is so good as we saw last night.(as 作saw 的宾语)

Cf.The film is so good that we moved to tears.(that是连词，不作句子成分,引导结果状语从句)

Last night we saw such a good film as we had expected.(as作expected的宾语)

Cf.Last night we saw such a good film that we thought it's worth seeing again. (that是连词，不作句子成分,引导结果状语从句)

2．She is such a good girl ＿＿＿＿does well in French．

篇14：桑建强：高考化学复习教案2

桑建强：2011年高考化学复习教案（2）

课题1 强电解质和弱电解质一、教学目标 1、知识与技能：基本要求：了解强弱电解质在水溶液中电离程度的差异及其原因，能正确书写电离方程式。 2、过程与方法：由于本课题中涉及的基本概念和基本理论比较抽象，应使学生认识到这些原理的形成是由特殊到一般、由具体到抽象、由现象到本质的认识过程，并在感性认识到理性认识的不断循环中培养学生归纳、演绎等逻辑推理能力。 3、情感态度与价值观：教学中定性分析和定量计算想结合、感性认识和理性分析想结合，充分运用逻辑推理，训练学生的形象思维，培养学生对化学理论的学习兴趣，为部分学生将来的发展奠定基础。二、教学重点、难点 1、重点：强弱电解质的差异、书写电离方程式 2、难点：书写电离方程式三、教法与学法启发式、讨论法四、教学准备课题1 强电解质和弱电解质.ppt 实验准备：仪器：锥形瓶气球 PH试纸（最好是pH计）药品：1mol/L HCl 1mol/L CH3COOH 镁条五、教学过程设计 [知识回顾](1)什么叫电解质？举例说明。(2)什么叫非电解质？举例说明。 [练一练]见ppt [想一想]见ppt [师]通过练一练、想一想小结 [板书] 一、电解质和非电解质混合物纯净物单质化合物电解质物质非电解质注意：（1）单质、混合物既不是电解质也不是非电解质。（2）CO2、NH3等溶于水得到的水溶液能导电，但它们不是电解质，因为导电的物质不是其本身（3）难溶的盐(BaSO4等)虽然水溶液不能导电，但是在融化时能导电，也是电解质 [你知道吗?]见课本p58，学生用所学解释。 [师]电解质在水溶液中能导电是因为能电离出自由移动的离子，不同电解质电离的程度是否一样呢？ [活动与探究]书p58，1．醋酸和盐酸是常见的两种酸，根据你的经验，你认为它们的.电离程度有无差异?请说出你的理由。 [生]根据常识我们知道盐酸酸性比醋酸强，所以盐酸的电离程度大。 2．你能设计实验验证你的猜想吗?请写出实验方案并与同学交流。 [学生活动]设计实验比较CH3COOH与HCl的电离程度或者酸性强弱的方法。。 [师]听取学生的方案并评价。再给出一系列的方案方案一：配置相同浓度的盐酸和醋酸溶液测定其PH值。方案二：取相同体积，相同浓度的盐酸和醋酸溶液与相同质量的金属（如镁、铝）反应，比较反应速率。方案三：配制相同浓度的盐酸和醋酸溶液测定其导电性强弱方案四：配制PH相同的盐酸与醋酸溶液，各取1mL稀释100倍，测定稀释后的PH值。（醋酸pH值变化慢）方案五：配制PH相同的盐酸与醋酸溶液，分别取相同体积，用酚酞做指示剂，以氢氧化钠溶液来滴定，测定消耗的氢氧化钠溶液的量。（醋酸消耗氢氧化钠溶液多）方案六：配制相同浓度的NaCl溶液和CH3COONa溶液测定pH值。（CH3COONa显碱性）方案七：配制pH相同的盐酸和醋酸溶液，与足量的锌反应，用排水法收集氢气。（醋酸溶液收集到的氢气多） …… [说明]方案1-3学生用现有知识能理解，方案4-7用现有知识无法解决为后面的学习埋下伏笔，让学生知道解决问题的方法是多样的就可以了。 [师]现在我们就用其中的两种方案来验证一下醋酸和盐酸的电离程度。 [活动与探究]教师演示实验，学生思考原因，并尝试解释 [结论] 实验一说明：相同浓度盐酸的pH值小于醋酸的pH值，也就是说相同浓度的盐酸中氢离子浓度大于醋酸中的H+浓度，即盐酸电离程度大于醋酸。实验二说明：相同体积，相同浓度盐酸与镁条反应更剧烈，也就是说相同浓度的盐酸中氢离子浓度大于醋酸中的H+浓度，即盐酸电离程度大于醋酸。两个实验都证明了盐酸的电离程度比醋酸大。更精确的实验证明了HCl在水溶液是完全电离的而醋酸是部分电离的。我们把在水溶液中完全电离的电解质成为强电解质，而部分电离的电解质称为弱电解质。 [板书] 二、强电解质和弱电解质 [问题探讨] 见ppt，强弱电解质的区分依据不是看该物质溶解度的大小,也不是看其水溶液导电能力的强弱,而是看溶于水的部分是否完全电离. 说明1、电解质强弱和能否完全电离有关而于溶解性无关 2、导电性强弱与溶液中的离子浓度有关。 [问题解决1]见课本p59-60 方案一：测浓度下的pH值；方案二：测同浓度下的导电性。 [师]下面我们一起来看看强弱电解质的分类。板书写出下表电解质强电解质弱电解质强酸强碱盐 HCl、HBr、HI、H2SO4、HNO3 HClO4 NaOH、KOH、Ca（OH）2 Ba（OH）2 NaCl、NH4NO3、BaSO4、AgCl等弱酸弱碱水 H2CO3、H2SO3、H3PO4、H2S、HClO、CH3COOH、苯酚、HF NH3・ H2O、不可溶的碱如 Cu（OH）2、Fe（OH）3 大部分金属氧化物 [练习]见ppt [问题解决2] 见ppt，醋酸和氨水都是弱电解质，不完全电离；而反应生成的醋酸铵是强电解质，完全电离. [师]电解质的电离我们用电离方程式表示。见ppt [板书] 三、电离方程式强电解质在溶液中完全电离，用“＝” 弱电解质在溶液中部分电离，用“ ” 多元弱酸的电离应分步完成电离方程式，多元弱碱则一步完成电离方程式. 例：NaCl CH3COOH H2S NH3・H2O Al（OH）3 NaHSO4 NaHCO3 [小结]强、弱电解质的比较
