Section I 课前准备、听力、口语

1.Try the quiz below to see if you know any better.试一试下面的知识检测，看看你是否了解的更多。(P.9 Question 2)if:(1)if conj.“是否”，在此语境中可用whether 代替。He asked whether / if we wanted a drink.他问我们是否要喝点饮料。注意：whether与if(作“是否”解时)都可以连接宾语从句。

(2)if不能替换whether的5种情况：a.正式文体中，句中有or not时I wonder whether it is big enough or not.我想知道它是否足够大。注意：在口语中“if...or not”可接受，但连写的“if or not”是错误的。b.引导主语、表语、同位语从句时：Whether it is true(or not)remains a question.它是不是真的还是一个问题。c.作介词宾语时I haven't settled the question of whether I'll go back home.我还没决定是否要回家。d.在不定式前，与不定式组成词组She hasn't decided whether to go or not.她还没有决定去还是不去。e.作discuss等词的宾语We discussed whether we should close the shop.我们讨论是否该关闭那家商店。

(3)if还有“假如”之意，引导条件状语从句，而此时的条件状语从句，又具体分为两种情况：表示真实条件和表示假设条件，详解如下：

a.表示真实条件。“如果” If he told you that, he was lying.如果他是那样对你说的，他就是在撒谎。If it rains tomorrow, we will stay at home.如果明天下雨，我们就不出去。

注意：if条件句要求用一般时表示将来，不用will表示将来，只有在表示“愿意”或“不愿意”时，if后才可以跟will或won't。If you won't come, I'll go alone.如果你不愿意来，我就一个人去。

b.表示假设条件，“假如”，用虚拟语气与现在事实相反 If I were you, I would help her.我要是你的话，我就会帮助她。

与过去事实相反 If I had not missed the train, I would have got home by now.假如我没误了火车，现在早该到家了。与将来事实相反 If any one should call, please let me know.万一有人打电话来，请告诉我一声。

拓展：as if(=as though)好像(引导方式状语从句或表语从句);even if(=even though)即使(引导让步状语从句);if only(引导感叹句，要用虚拟语气)但愿，要„„就好了;(引导状语从句，要用虚拟语气)要是，若是;only if(引导状语从句，用陈述语气)只有

(1)which既可引导定语从句，又可连接名词性从句；而what不可引导定语从句。

(2)which，what同为名词性从句的连接代词时，都可在所连接的名词性从句中充当主语或宾语，其区别在意思上。what强调“内容”，而which强调从已知的、确定的范围中做出选择。This river, which flows through London, is called the Thames.(which引导非限制性定语从句)这条流经伦敦的河，叫泰晤士河。What book are you going to read? 你要读什么书?

Which book are you going to read, this one or that one? 你要读哪一本书，这本还是那本? 注意：以下句子中常用what。(1)What season do you like best? 你最喜欢什么季节?(2)What day is today? 今天是星期几?(3)What's the date today? 今天是几号? 联想：somewhat adv.稍微，有点whatever pron.无论什么；凡是„„的东西

比较：He didn't need to come last night.他昨晚不必来。(实际上也没有来)辨析：need, require与want:(1)三者后接名词、代词或数词，意思为“要”或“需要”。三者后接被动的不定式或主动的动名词，意思为“需要”或“应该”。(2)need(需要)和want(想要)可以接主动的不定式作宾语，而require不可以。(3)require和want可以接复合宾语，而need不可以。(4)require可以接宾语从句，而且从句中的谓语动词必须用“(should+)动词原形”；need和want不可以。(5)need可以作情态动词，而require和want不可以。例如：The work needs / requires / wants patience.这工作需要耐心。The house needs / requires / wants to be cleaned / cleaning.这房子需要清扫。He needs / wants to see you.他要见你。I require / want you to be here this evening.我请你今晚到这儿来。They require that I(should)appear.他们要求我出场。You need not write down your translation.你们不必写下译文。联想：(派)needful adj.需要的，必须的needless adj.无需的，不必要的needlessly adv.不需地，无谓地 needy adj.贫穷的，贫困的

I hope we'll be friends and come to understand each other.我希望我们成为朋友并逐渐相互理解。He came to realize that he was wrong.他开始认识到自己错了。辨析：get，go，turn与come

get强调造成事件的施动者发挥的作用或变化的结果。go常常表示不顾施动者的愿望而发生的变化，多用于表示恶化的情况。turn经常表示从某种状态向其对立状态转化的自然现象。come

大都表示向好的方面转化。They got married 10 years ago.他们10年前结的婚。Please don't get angry.请别生气。The eggs went bad.鸡蛋坏了。The telephone has gone dead.电话断了。The weather has turned much colder.天气变得冷多了。Everything will come right in the end.最终一切事情总会变好的。

5.Doctors may find a way to keep us young forever.医生可能会找到一种让我们青春永驻的办法。(P.10 Speaking “Young forever” 第二个A)部分名词后接不定式或介词 + 动名词 1)在chance，way，opportunity，time等名词后，既可用不定式，又可用“介词 + 动名词”作定语。如：I'd like to have a chance to see / of seeing your teacher.我想找个机会见一个你们的老师。I'm glad to have the opportunity to talk / of talking to you.我很高兴能有这个机会跟你谈话。2)在ability，resolution，tendency等名词后，通常用不定式作后置定语。如：Does he have the ability to do the work? 他有做这项工作的能力吗? He has made a resolution to go abroad.他决心出国。She has a tendency to become fat.她有发胖的趋势。

3)当被修饰的普通名词前有序数词修饰时，该名词的后置定语也须用不定式而不是“介词 + 动名词”。Antonio Gaudi is the first one to understand that.安东尼奥是第一个理解那件事的人。He is always the first one to come and the last one to leave.他总是第一个来，最后一个离开。

4)而在habit，idea，intention，method，objection等名词后，通常只跟“介词+动名词”作定语。I have the habit of taking a nap after lunch.我有午饭后睡午觉的习惯。She dismissed the idea of becoming an artist.她打消了当艺术家的念头。He had no intention of keeping his word.他不想遵守诺言。We like his methods of teaching English.我们喜欢他教英语的方法。He had an objection to(prep.)doing it.他反对做此事。

since时间从句中，不论用短暂动词、延续动词还是状态动词的一般过去时，通常都表示从动作或状态的完成或结束时算起，因此这种since从句应理解为“自从该动作结束以来”。如：Great changes have taken place here since he left.自从他离开以来，这里发生了巨大的变化。

提示：(1)从句中使用延续性动词时，常容易误解。(2)如果要表示从句中的动作或状态延续至今，该动词须用现在完成时，有时也可以用一般过去时，但这时需要在since前加ever，强调与现在的联系。如：I haven't heard from him since he lived(was)in Beijing.自从他离开北京，我没有收到过他的来信。How long is it since you smoked? 你戒烟多久了(或你多长时间没抽烟了)?I have known her since I have lived here(或ever since I lived here / since I lived here).从我住到这儿以来，我就认识她。

with which: 非限制性定语从句“介词+引导词”: 在非限制性定语从句中，因which在从句中充当介词宾语，一般将介词置于关系代词which的前面(固定的动词词组除外)。类似的用法有：There is a room, the window of which faces the river.有一问房子，窗户朝着这条河。The wrong you've done him is terrible, for which you should make an apology to him.你太冤枉他了，因为这件事，你该向他道歉。

尊敬的领导、老师，你们好：

今天我说课的课题是高二英语下册《Unit 20 Archaeology》中的Warming up, Listening & Speaking的内容。（演示第一张）

首先，我将对这一单元的知识背景做一介绍。本单元围绕考古这一主题开展听、说、读、写多种教学活动。旅游作为当今社会人们最感兴趣的话题在英语学习占有非常重要的位置，名胜古迹是旅游的重点内容之一，名胜古迹中的许多发现都来自于考古工作，所以Archaeology 也是一个非常贴近生活，具有时代性，可挖掘性的教学主题。本单元所选的语言素材涉及中外名胜，有利于学生了解外国文化，增强世界意识。

本课的教学重点要求 1.学生能利用所学知识谈论古代人们的饮食起居、文化娱乐、生产工具等，为以后阅读英国的《巨石王》和中华文明的起源奠定基础。2.调动学生的积极性，组织他们利用表达好奇功能结构谈论他们所感兴趣话题。针对以上两点，教学过程中主要采用的是让学生做表格，看例子，练习对话的方式来巩固知识点。

听力是这一课的难点。听力材料介绍是古代法国人用来射箭的一种武器。材料长，对武器结构的解释比较复杂。所以对学生来说只要求能回答课后问题就好了，不要求了解细节。

从情感态度方面来说，通过在学习过程中看图说图的方式，能激发学生学习积极性，这是其一。其二是从谈论石器时代、青铜器时代、汉朝、唐朝等时代人们的饮食起居、文化娱乐、生产工具等入手使学生到认识到中国是个有着悠久历史灿烂文化的文明古国，增强学生的民族自豪感，爱国主义情操，增强学生学好英语的自信心。

在本课的授课过程中，我从网上下载了大量和考古出土文物相关图片，目的是为了使学生能对考古学产生兴趣，形成一个有关考古学的信息包，对考古学及中国古代所取得的成就有初步的了解和印象。如果用传统的教学模式，很难达到理想的教学效果，而利用多媒体课件进行教学，不仅可以完成教学任务，还可以收到良好的教学效果。

所以，第一步要做的是通过多媒体课件文字资料，让学生了解本节课的教学目标，包括两个方面的内容，即掌握与考古相关的重点词汇和学会表达对什么东西的好奇。

第二步是通过展示两张反映不同时代出土文物的图片资料，调动学生的学习情绪，引起他们对考古学的兴趣，增强文化和考古意识，为以后学习英国《巨石王》和中华文明的起源奠定基础。

第三步是通过多媒体课件的文字资料展示本课重点词汇及相关用法，老师做简要解说。然后通过课件展示四幅不同时代的出土文物图片，让学生对不同时代人们的起居生活、饮食习惯，生产工具，娱乐活动等进行深入讨论并加以总结，结果则由老师在多媒体课件上以图表的形式展示，这样做较传统方法节约了大量板书的时间，重难点也更为突出。

第四步是通过展示更多的不同时代的图片资料，进一步深化学生对不同时代的认知，提高学生的学习热情。

第五步的听力部分我是这样处理的：首先通过课件展示听力部分文字材料及听力要求，让学生带着问题去听，然后听录音材料三遍后，要求学生完成听力练习，通过绘图、填空等练习形式来分解难点，降低学习的难度，通过课件展示的文字材料讲解答案，这样做较传统方式更为轻松，学生也更容易接受。

第六步是通过课件展示的文字资料演示口语训练的三个基本步骤，即首先给出范例，并对范例进行一定的讲解，其次给出一些用来表达自己愿望的句型，要求学生以双人对话的形式，按照例子，用所提供的句型和话题进行对话。对考古学以及考古学的重要发现提出自己的意见和看法。本部分的目的在于促进同学们对考古及考古学的思考，又促进同学在陈述观点过程中的口头表达能力和语言组织能力。这样做使得课堂口语教学能得以有条不紊的进行，很好地完成教学任务。

总之，采用现代教育技术向学生传授知识，改变了传统教学过程的模式，许多抽象的难以理解的东西都变得形象生动了，易于被学生接受，更好的调动了学生学习的积极性，激发了更大的学习热情；多媒体板书则优化了板书形式，节省了大量的课堂时间，真正做到了高效率教学，为老师补充更多的课外知识预留了时间，符合素质教育的要求。

第五篇：七年级英语下册Unit12 Don

七年级英语下册Unit12 Don’t eat in class.泰来二中：刘丽

我讲课的内容是人教社出版的七年级英语下册Unit12 Don’t eat inClass.Section A的部分内容。根据新课程标准强调学生的学习过程，重视语言学习的实践性和应用性，并以全体学生的全面发展为出发点，我对教材进行从新的分析和整合，下面我就从教材分析、教学方法和手段、教学流程，教学评价等几方面来谈谈我本节课的教学思路，并与大家共同探讨。并希望得到各位评委的指正。

一、教材分析和处理

1、教材的地位和作用。

根据新课程标准，初一阶段要求学生能用了解学校家庭的规章制度，并了解西方国家独特的规章制度，扩大视野，拓展知识面。而本单元的教学重点是使学生正确理解掌握这些知识并能够灵活的运用他们。而我所讲的这节课在本单元中起着抛砖引玉的作用，所以说这一节课完成的好坏，直接影响到本单元的授课效果。

2、教学目标，重、难点的确立及依据。

英语课堂教学的目标是通过通过英语学习形成初步的综合的语言运用能力，促进心智发展，提高综合人文素养。本节课的教学目标通过听、说、读、写四项基本技能的训练，培养学生初步运用英语进行交际的能力。因此本节课的教学目标包括知识目标，过程与方法及情感态度价值观三个方面。即通过学生学习掌握祈使句的构成及用法，并通过自主学习，合作学习能够准确的制定一些规章制度，从而

培养学生良好的行为习惯。

二、教学方法和手段

1、教学方法。

本节课我除了采取以提纲导学为主自主学习的方法外，同时还采取小组合作，竞赛等方法，通过多种方法的配合使用，既调动了学生学习的热情、活跃了课堂气氛，也使整节课达到了预期的教学效果。

2、教学手段。

本节课我充分利用网络资源，在课前我下载了大量的课件，并将他们从新整合，以达到我所想要的教学效果。通过课件的展示，让学生对课内容有个初步认识，再以此为依据顺利开展接下来的教学环节。这种先进教学手段的使用，不仅丰富了课堂教学内容，也极大地调动学生学习的兴趣，使学生学习起来既积极思维而不紧张，既轻松愉快而不懈怠，达到了教与学的有效对接。

三、教学流程

1、新课导入。

本节课的内容是围绕谈论校规展开的，在上课前几分钟内，我让学生学唱一首根本课内容有关的英文歌曲，在新授课开始前我让学生进行例行值日生报告，因为是学习新的话题，所以在课前我就为作报告的的同学设置一个有关如何做一个合格的中学生的题目，并对他的报告做出非常肯定的评价并让其他同学以此为榜样。这样做从一开始就吸引住了学生的注意力，也让我自然而然地导入本节课所要学的内容。

2、实施目标。

本节课的教学目标在前面我已经提到，为了更好的完成教学目标我主要设计了如下几个小环节;

(1)学习新单词及短语

记忆新单词一直是学生比较头疼的问题，为更好地解决这一问题，在课前我让学生自己先预习本节课单词，在课上，我首先利用多媒体课件展示这些新词，然后在通过竞赛方式检查学生的掌握情况，这样做可调动学生记忆单词的热情，也使枯燥知识也变得直观，生动和有趣，学生学习起来比较轻松。

（2）分析、讲解本节课的重难点内容。

本节课重点知识是讲解祈使句，及else的用法。为了便于学生更好地理解和掌握所学知识，我采取了成成深入的办法。首先出示两张张图片，让学生讨论，并对学生进行思想教育，接下来又展示一组不同的图片让学生做两人一组的对话、然后让学生以抢答的方式复习刚刚学过的内容。通过这样的反复练习，学生已经初步通过本节课知识点。接下来我让学生拿出本节课的导学提纲，来检查学生的自主学习情况，对学生在导学提纲中不完善的地方加以补充和说明。这样的做法一方面增加了课堂容量，学生活动范围广，学习热情高，也培养了学生自主学习的意识，更便于教师了解掌握学生的学习情况。

3）听力训练。

我们知道这套教材非常重视听力训练，尤其在每单元开始的部分，这也体现出英语教学的实效性。本节课我把听训练放在重要位置。首先，我利用大屏幕展示说要听的材料内容，然后放录音，让学生根据所听内容完成习题，最后在核对答案。这样，通过教师的引导，不仅帮助学生掌握正确的听力方法，而且也培养了学生良好的听力习惯。

（4）巩固训练。

巩固训练是对学生所学知识的一种检查。本节课的巩固训练，我主要采用做调查形式。即设计情景，让学生以小组合作的形式进行，并且要求学生结合本课所学内容，完成调查表，这一活动不仅调动了学生学习的积极性，同时也进一步加深了学生学习的印象，收到了事半功倍的效果。

以上四个小步骤是实施目标阶段，在实施目标阶段结束后，就进入了教学程序的第四个环节。

4、达标测试。

达标测试是学生在感知和理解的基础上，进一步巩固其所学知识，达到熟练运用程度。

5、反馈矫正。

通过提问的方式，对达标测试中出现的问题及时进行矫正，这一环节有助教师了解教学效果和学生的掌握情况，所以是教学环节中不可缺少的必要的组成部分。

6、归纳总结。

这一环节旨在帮助学生复习、巩固所学英语语言知识和技能。在这一环节中，我主要采用了提问的方式，这样一方面进一步强化了学生对新学内容的记忆，另一方面也可以发现问题，以便及时采取补救措施。

7、布置作业。

本节课作业要求学生根据所学内容写一篇有关家规的文章，目的是为检查本节课的授课效果，拓展所学知识，同时也再一次对学生进教育，培养学生良好的行为习惯，从而达到情感教育的目的，并实现本节课的情感目标

四、教学评价

在整个教学过程中，通过不同环节的设计，不仅拓展了教学内容，也增加了课堂容量。多媒体课件的使用，曾添了趣味性，也符合初一学生的年龄特点。学生通过做游戏、小组合作，自主学习也表现了很高的参与性，但同时也存在着一些缺憾：由于课堂时间有限，调查报告当堂检验组数应增加，这也提醒我在以后的教学活动中要更进一步去研究、去完善，力争做得更好。
