在此谢谢各位园长!

景德镇教招面试:教案如何撰写?
一、教案内容
教案是教师为顺利而有效地开展教学活动,根据课程标准,教学大纲和教科书要求及学生的实际情况,以课时或课题为单位,对教学内容、教学步骤、教学方法等进行的具体设计和安排的一种实用性教学文书。教案包括教材简析和学生分析、教学目的、重难点、教学准备、教学过程及练习设计等,但在我们实际的教师招聘考试中,尤其是在备课时间不是太长的情况下,教案应主要包括教学目标、教学重难点、教学过程以及板书设计四个方面,一下着重介绍一下教案中的四个内容。
二、教案的主要方面
(一)教学目标
1.知识与技能目标:掌握(某些知识),能运用(某些知识)解决生活实际问题等
2.过程与方法目标:通过/经历„„的过程,形成/提升„„能力
3.情感态度与价值观目标:感受物理与生活的联系,获得成功的体验,提升学习物理的兴趣等
在教学目标这里需要注意的是,在新课标标准下,在制定教学目标时,应该以学生为主体,教师起引导作用,因此在撰写教学目标时应避免出现“使学生„”、“让学生„”等等,以及不要出现提高学生,增强学生等字样。
(二)教学重难点
1.教学重点:教学重点是在学习过程中重要的部分,需要学生掌握的部分,一般体现在课题,课后习题,概念知识等等。具有稳定性和长期性。
2.教学难点:教学难点是学生在学习过程中遇到的困难部分,难以理解的地方,难点被理解之后就不是难点了,一般体现在学生把握不好的地方、知识点的探究过程、应用解决实际问题的知识点等等。具有暂时性和相对性。
注意:教学重难点在教学过程中要有体现。
(三)教学过程
在这一过程中主要包括四个方面,导入新课、讲授新课、巩固练习、小结作业。
1.导入新课
一般采用温故知新导入,多媒体导入,故事导入等。
(1)设计新颖活泼,精当概括。
(2)怎样进行,复习那些内容?(3)提问学生。
2.讲授新课
(1)针对不同教学内容,选择不同的教学方法。
(2)怎样提出问题,如何逐步启发、引导?(3)教师怎么教,学生怎么学?详细步骤安排。
3.巩固练习
(1)练习设计精巧,有层次、有坡度、有密度。
(2)怎样进行,对哪些学生进行提问? 4.小结作业
(1)怎样进行,是教师还是学生归纳?(2)时间如何把握?(3)布置哪些内容,要考虑知识拓展性、能力性。
(4)需不需要提示或解释?
(四)板书设计
板书设计要力求清晰,教师备课时要在充分研读教材的基础上,为每一节课设计出具有如下特点的板书方案:一是严密的逻辑性,板书顺序是逻辑推理的高度概括再现;二是概括性,高度概括本课的教学主要内容;三是符合审美要求,板书设计要符合审美规律,中公解析,给人以明确清晰、美观大方的良好审美感受;四是结构的完整性,即对一个知识点的全面完整表述;五是创新性,每个人即使在讲同一内容时由于文化背景、思维方式、表达方式、习惯等因素的差异作用,板书都体现出自己的特点,即个性化。因此板书设计可以借鉴、参考,但决不能照搬照抄。

虚拟条件句
2009年10月20日 星期二 15:27 虚拟条件句的三种基本类型:与现在事实相反、与过去事实相反、与将来事实相反。
条件句有真实条件句和非真实(虚拟)条件句两种。真实条件句所表示的假设是有可能发生的,而非真实条件句则通常表示一种假想,与事实相反或不大可能会发生:
If I have time, I will go with them.假若我有时间,我就同他们去。(陈述语气)If I were you, I would go with them.假若我是你,我就同他们去。(虚拟语气)▲ 与现在事实相反
若与现在事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用‚should(would, could, might)+动词原形‛:
If I knew her number,I could ring her up.要是我知道她的电话号码,我就可以给她打电话了。(可惜我不知道)▲与过去事实相反 若与过去事实相反,条件从句的谓语用过去完成时(had+过去分词),主句谓语用‚should(would, could, might)+have+过去分词‛:
If I’d left sooner,I’d have been on time.要是我早点动身,我就准时到了。(但我动身太迟了)▲与将来事实相反
若与将来事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用‚should(would, could, might)+动词原形‛:
If I asked him,I’m sure he’d help us.如果我向他提出要求,肯定他会帮助我们。(不过我不打算这样做)注:几点特别说明
① 主句谓语中的should主要用于第一人称后。would, might, could的大致区别是:would表示结果,might表示可能性,could表示能力、允许或可能性。比较:
If you tried again,you would succeed.要是你再试一试,你就会成功的。(would表结果)If you tried again,you might succeed.要是你再试一试,你可能会成功的。(might表可能)If you tried again,you could succeed.要是你再试一试,你就能成功了。(could表能力)④ 对于与将来事实相反的情形,请注意以下几点:一是这里说的与将来事实相反,实为对将来情况的推测;二是此用法中的条件从句谓语除用过去式外,有时也用‚should+动词原形‛(表示可能性极小,常译为‚万一‛)或‚were to+动词原形‛(表示与将来事实相反的假设);三是当条件从句使用‚should+动词原形‛这样的谓语时,主句谓语除可用‚should(would, could, might)+动词原形‛这样的虚拟语气外,也可用直陈语气或祈使语气:
If it should rain tomorrow, don’t expect me.万一明天下雨,就不要等我了。(祈使语气)
If I should see him, I’ll tell him.万一我见到他,我就告诉他。(直陈语气)
2、错综时间虚拟条件句
所谓错综时间虚拟条件句即条件从句与主句所指时间不一致,如从句指过去,而主句即指的是现在或将来,此时应根据具体的语境情况,结合上面提到的三种基本类型对时态作相应的调整:
If it had rained last night, the ground would be wet now.要是昨晚下过雨的话,现在地面就会是湿的。
You would be much better now if you had taken my advice.假若你当时听我的话,你现在就会好多了。
3、两个常考虚拟语气句型 ▲ 句型介绍
这两个句型是If it weren’t for…和If it hadn’t been for…,这是两个很常用的虚拟语气句型,也经常受到命题人的青睐,其意为‚若不是(有)‛‚要不是有‛。如:
If it weren’t for water, no plant could grow.要是没有水植物就无法生长。
If it hadn’t been for your aistance,we wouldn’t have succeeded.=But for your aistance,we wouldn’t have succeeded.=Without your aistance,we wouldn’t have succeeded.5、wish后宾语从句用虚拟语气 ▲ 用法说明
动词wish后接宾语从句时,从句谓语要用虚拟语气。若要表示与现在事实相反的愿望,从句谓语用一般过去时或过去进行时;若表示与过去相反的愿望,从句谓语用过去完成时或would / could+have +过去分词;若表示将来没有把握或不太可能实现的愿望,用would(could)+动词原形。如: 注:特别注意
从句的时态只与从句所指的时间有关,而与wish的时态无关,比较: I wish I were rich.要是我现在有钱就好了。I wish I had been rich.要是那时我有钱就好了。I wished I were rich.当时我后悔自己没有钱。
I wished I had been rich.当时我后悔自己曾经没有钱。
6、if only后的句子用虚拟语气
if only 与 I wish一样,也用于表示与事实相反的愿望,其后所虚拟语气的时态与 wish后所接时态的情况相同:
If only she had had more courage!她再勇敢一些就好了。
If only I had listened to my parents!我要是当时听了父母的话就好了。If only she would go with me!她要是愿意和我一道去就好了!注:if only 通常独立使用,没有主句。
7、as if(though)从句用虚拟语气 ▲ 基本用法
以as if(as though)引导的方式状语从句或表语从句,有时用虚拟语气,若表示与现在事实相反,谓语动词用一般过去时;若表示与过去事实相反,用过去完成时;表示将来的可能性不大,用would(might, could)+动词原形: He acts as if he knew me.他显得认识我似的。
They treat me as though I were a stranger.他们待我如陌生人。He talks as if he had been abroad.他说起话来好像曾经出过国。注:两点说明
(1)从句所表示的内容若为事实或可能为事实,也可用陈述语气: It looks as if we’ll be late.我们似乎要迟到了。(2)注意 It isn’t as if…的翻译:
It isn’t as if he were poor.他不像穷的样子(或他又不穷)。
8、It’s time后的从句用虚拟语气 ▲ 基本用法
从句谓语通常用过去式表示现在或将来,有时也用过去进行时或‚should+动词原形‛(较少见,且should不能省略),其意为‚(早)该干某事了‛: It’s time we went [were going, should go].我们该走了。It’s time I was in bed.我该上床睡了。(不用were)
9、would rather后句子用虚拟语气
在would rather, would sooner, would just as soon 后的that从句中, 句子谓语习惯上要用虚拟语气,表示‛宁愿做什么‛,具体用法为: ▲ 一般过去时表示现在或将来的愿望
I’d rather you went tomorrow(now).我宁愿你明天(现在)去。▲ 用过去完成时表过去的愿望
I’d rather you hadn’t said it.我真希望你没有这样说过。
10、宾语从句用虚拟语气的10种类型 ▲ I wish后的宾语从句
动词wish后接宾语从句时,从句谓语要用虚拟语气。若要表示与现在事实相反的愿望,从句谓语用一般过去时或过去进行时;若表示与过去相反的愿望,从句谓语用过去完成时或would / could+have +过去分词;若表示将来没有把握或不太可能实现的愿望,用would(could)+动词原形。如: I wish I could be of some use.我希望我能有什么用处。We wish he didn’t smoke.我们希望他不吸烟。
I wish prices would come down.我希望物价能降下来。▲ 表示‚坚持‛后的宾语从句
主要是指insist的宾语从句,从句谓语由‚should+动词原形‛构成,其中的should在美国英语中通常可以省略。如:
I insisted that he(should)stay.我坚持要他留下。
注:动词insist后接宾语从句时,除可用虚拟语气外,也可用陈述语气,两者的区别是:若谓语动词所表示的动作尚未发生,或尚未成为事实,则用虚拟语气;若谓语动词所表示的动作已经发生,或已经成为事实,则要用陈述语气。比较: He insisted that I had read his letter.他坚持说我看过他的信。He insisted that I should read his letter.他坚持要我看他的信。▲ 表示‚命令‛后的宾语从句
主要是指order, command的宾语从句,从句谓语由‚should+动词原形‛构成,其中的should在美国英语中通常可以省略。如:
He ordered that it(should)be sent back.他命令把它送回去。▲ 表示‚建议‛后的宾语从句
主要是指advise, suggest, propose, recommend等的宾语从句,从句谓语由‚should+动词原形‛构成,其中的should在美国英语中通常可以省略。如: He suggested that we should leave early.他建议我们早点动身。
注:与动词insist相似,动词suggest后接宾语从句时,除可用虚拟语气外,也可用陈述语气,两者的区别也是:若谓语动词所表示的情况尚未成为事实,则用虚拟语气,此时suggest通常译为‚建议‛;若谓语动词所表示的情况为既成事实,则要用陈述语气,此时的suggest通常译为‚表明‛、‚认为‛。比较并体会:
He suggested that we(should)stay for dinner.他建议我们留下吃饭。I suggested that you had a secret understanding with him.我觉得你与他心照不宣。
▲ 表示‚要求‛后的宾语从句 主要是指ask, demand, require, request等后的宾语从句,从句谓语由‚should+动词原形‛构成,其中的should在美国英语中通常可以省略。如: I ask that he leave.我要求他走开。
He requires that I(should)appear.他要求我出场。▲ 表示‚提议‛‚投票‛后的宾语从句
主要是指move, vote等后的宾语从句,从句谓语由‚should+动词原形‛构成,其中的should在美国英语中通常可以省略。如:
I move that we accept the proposal.我提议通过这项提案。▲ 表示‚敦促‛后的宾语从句
主要是指动词urge后的宾语从句,从句谓语由‚should+动词原形‛构成,其中的should在美国英语中通常可以省略。如:

as if 引导的从句(表示非真实时)但表真实时,不用虚拟语气。与虚拟语气条件中从句动词形式基本相同。1.Tom speaks as if he were a girl.2.He looks as if he had been to Beijing.so that, in order that引导的目的状语从句 May/might/should +V原 I live so that others may live better.It is(the very/high)time that后的定语从句 从句谓语动词常用过去式,有时也可用should+动词原形 It is(high)time that we went(should go)to bed.It is time that I were leaving.省去主句的If only(要是……就好了)虚拟条件句 与wish后的宾语从句谓语形式相同。If only I hadn’t lost the chance!(= I wish I hadn’t lost the chance)某些表祝愿的句子 常用原形或‚May+动词原形‛ Long live world peace!May you be happy1 表委婉客气的是常语句 情态动词的过去式+动词原形 Could I borrow your bike? Would you please give me a hand? 虚拟语气的用法
虚拟语气表示一种假设的情况,或一种主观的愿望,即动词所表示的动作或状态并非事实,或不可能实现。英语虚拟语气的形式有下列几种:
一、与现在事实相反
连接词 条件从句 结果从句 If 1.动词过去式(或were)2.助动词(过去式)+动词原形 Should Would +动词原形 could might If had the time, John would make a trip to China to see the Great Wall.If I were you, I would give up drinking immediately.二.与将来事实相反
连接词 条件从句 结果从句 If 1.should+动词原形 2.动词过去式
3、were to+动词原形 Should Would +动词原形 could might If you should lose, what would you do? If I were to see her tomorrow, I would tell her thetruth.If you went there next time, you would see what I mean.三、与过去事实相反
连接词 条件从句 结果从句 If had+过去分词 Should Would + have+过去分词 could might If I’d dnown that it was going to rain, I would never have gone for a walk in the country.四、虚拟语气的几种特殊用法 省掉if的条件从句结构:
Had you asked me, I would have told you.(=If you had asked me,…)2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示,如:
A true friend would not do such a thing.(=If he were a true friend, he...)
(=If there were no water,…)
(=If you hadn’t helped me,…)3.有时条件从句中的动作和结果从句中的动作发生的时间不一致,如:
If he had followed the doctor’s advice, he would be quite all right now.If I were you, I would have gone home.五、虚拟语气的其他用法
1、Suggest, advise 等动词之后宾语从句须用虚拟语气,其句子结构如下: suggest, advise, recommend, demand, require, insist, urge, request, order, +that…(should)+动词原形 devide, ask, move, propose等
注意:在此结构中that不可省略;should省不省均可。He suggested that they(should)stop smoking.上述动词的名词形式出现时,that 引导的从句仍用虚拟语气。He made a request that they(should)stop smoking.如果that 引导的从句所表达的内容是事实,也可用陈述语气。He insists that he is right.2、It is(was)+neceary, a pity 等+that引导的从句须用虚拟语气,其句子结构如下:
imperative, advisable, 动词完成式
It is(was)+ important,natural, neceary, +that…(should)+ eential, strange,等 动词原形
It is important that you(should)follow the doctor’s orders.It is right that you should have done your homework.3、wish的用法
动词过去式或were—与现在事实相反
主语+wish(that)+主语 + 动词过去完成式—与过去事实相反 助动词过去试+动词原形—与将来事实相反
I wish I were a pop singer.(=I am sorry I am not a pop singer..)I wish I had never stopped teaching.(=I am sorry I stopped teaching.)I wish they’d let us get some sleep.注意:wish与hope接宾语从句的区别在于:hope表示一般可以实现的希望,宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。试比较:
(1)We hope they will come,(We don’t know if they can come.)(2)We wish they could come,(We know they are not coming.)
4、as if, as though, would(had)rather(that)引导的从句须用虚拟语气,如: He acts as if nothing had happened.I would rather you didn’t tell him.5、It’s (high)time that…+动词过去式或should+动词原形,如: It’s time(that)you had a hair cut.It’s high time(that)we took some action.Differences Between American and British English 2009年08月01日 星期六 08:23 Differences Between American and British English
While there are certainly many more varieties of English, American and British English are the two varieties that are taught in most ESL/EFL programs.Generally, it is agreed that no one version is "correct" however, there are certainly preferences in use.The most important rule of thumb is to try to be consistent in your usage.If you decide that you want to use American English spellings then be consistent in your spelling(i.e.The color of the orange is also its flavouror poible.The following guide is meant to point out the principal differences between these two varieties of English.Use of the Present Perfect
In British English the present perfect is used to expre an action that has occurred in the recent past that has an effect on the present moment.For example:
I've lost my key.Can you help me look for it? In American English the following is also poible: I lost my key.Can you help me look for it?
In British English the above would be considered incorrect.However, both forms are generally accepted in standard American English.Other differences involving the use of the present perfect in British English and simple past in American English include already, just and yet.British English:
I've just had lunch I've already seen that film Have you finished your homework yet?
American English: I just had lunch OR I've just had lunch I've already seen that film OR I already saw that film.Have your finished your homework yet? OR Did you finish your homework yet?
Poeion
There are two forms to expre poeion in English.Have or Have got
Do you have a car? Have you got a car? He hasn't got any friends.He doesn't have any friends.She has a beautiful new home.She's got a beautiful new home.While both forms are correct(and accepted in both British and American English), have got(have you got, he hasn't got, etc.)is generally the preferred form in British English while most speakers of American English employ the have(do you have, he doesn't have etc.)
The Verb Get The past participle of the verb get is gotten in American English.Example He's gotten much better at playing tennis.British Englishangry, bad humored, British Englishcondom, British Englishhood British Englishtrunk British Englishtruck British Englishon the weekend British Englishon a team British Englishplease write me soon British English-please write to me soon
Past Simple/Past Participles
The following verbs have two acceptable forms of the past simple/past participle in both American and British English, however, the irregular form is generally more common in British English(the first form of the two)and the regular form is more common to American English.Burn Burnt OR burned Dream dreamt OR dreamed Lean leant OR leaned Learn learnt OR learned Smell smelt OR smelled Spell spelt OR spelled Spill spilt OR spilled Spoil spoilt OR spoiled
Spelling Here are some general differences between British and American spellings:
Words ending in-or(American)-our(British)color, colour, humor, humour, flavor, flavour etc.Words ending in-ize(American)-ise(British)recognize, recognise, patronize, patronise etc.爱转了一圈到下一个路口,你要勇敢往前冲;每一段痛彻心扉的付出,都是珍贵的礼物;失去了一个不爱你的人,你应该感觉幸福;是你的你要把握住,不是你的请让路;退一步会海阔天空,爱本来就跌宕起伏

2016下半年四川教师公招面试备考之试讲:《直线的方程》教学设
计
一、教学目标 【知识与技能】
(1)理解直线方程的点斜式、两点式的形式特点和适用范围;(2)能正确利用直线的点斜式、两点式公式求直线的方程。【过程与方法】
通过自主探究、合作交流,体会几何问题代数化的过程,体会代数和几何之间的联系。【情感态度与价值观】
使学生在实践活动中,体会代数和几何的密切联系,增强学习数学的兴趣;学会与他人合作交流,获得积极的数学学习情感。
二、教学重难点 【重点】
直线的点斜式、两点式方程的理解和表示,能够利用直线方程解决相关问题。【难点】
直线点斜式方程的建立。
三、教学过程
上课过程利用问题导向,启发同学们自己得出结论。(一)导入新课 设疑导入
问题一:如何在平面内确定一条直线? 问题二:在平面内如何能用代数方法表示一条直线的方程呢? 这就是我们本节课要学习的内容。(二)探究新知
同学们经过思考讨论,由公理“过平面内两点能切仅能确定一条直线”得出确定直线的方法一。在此基础上,继续提问是否还有别的方法确定一条直线。经过思考,部分同学能得出由平面内一个定点和一个方向也能确定一条直线。适时点拨:几何中的点可以用代数中的坐标表示,那么方向该怎么表示呢?联系之前学过的任意角概念,启发同学们利用x轴正半轴旋转所成的角来确定直线的方向。顺势得出的方向角的概念,并澄清方向角的范围。
问题三:角度和长度是否是同一种量呢?他们之间是否存在着某种关联呢?他们之间在某种条件下是否能够相互转化呢? 小组讨论得出结论:长度和角度可以通过三角函数建立联系,通过三角函数实现用广义的长度来表示角度。进而启发学生,利用利用正切来表示倾斜角。教师补充斜率概念,并澄清斜率范围,斜率只能表示非90°的倾斜角。并引导学生得出斜率公式。
问题四:对于任意直线,如果已知斜率和直线所过的定点,如何用代数中的方程来表示该直线呢? 小组讨论,教师点拨:可以把直线看成点的集合,直线上的定点和定点外任意动点,满足斜率公式,由此可以得出直线方程。此方程即为直线的点斜式。
问题五:由公理“过平面内任意两个不同的点,能切只能确定一条直线”,我们能否由此公理得出直线方程呢? 小组讨论,得出结论:由两定点能确定直线的斜率。进而由直线的点斜式确定直线的方程。教师给出直线的两点式概念,给出两点式的标准方程。并点拨,两点式只能表示斜率存在的直线。对于斜率不存在的直线,可以直接由直线的横坐标得出直线方程。
(三)巩固提高
例1 求下列直线的方程:(1)直线l:过点(2,1),k=-1;(2)直线l:过点(-2,1),(3,-3).例2 求过点(0,1),斜率为-0.5的直线方程。练习A部分。(五)小结作业
小结:通过本节课我们主要学习了哪些知识?是如何得到这些知识的?对我们今后的学习有什么启发? 作业:课后习题1必做,习题2选做。
四、板书设计
