1、1强调句教案 “强调句” 教案教案I. 教学内容 : 强调句II. 教学目标:1. 理解强调句型的作用 : 用来对句中的某一部分(除谓语动词外)进行强调,以突出该部分在句中的意义.2. 记忆强调句型的结构: It is / was + 被强调的部分 + that + 原句中其它没有被强调的 部分.3. 会运用强调句型对一个句子中的相关部分进行强调.III. 教学重/难点:1. 强调句中 is / was 的运用.2. 强调句中 that / who 的运用.3. 强调句与主语从句的区别.4. 对 until 引出的时间状语 (从句)进行强调时的用法.IV. 教学分析:2由于该语法项目教学中运用
2、不多,学生比较陌生, 但历届高考中有的年份考到该项目, 所以复习中要对该项目进行必要的复习.在该项目中, 中等偏下的学生较难确定是用 is 还是用 was; 几乎所有的学生区别不了哪是强调句, 哪是主语从句. 因为, 由 it 作形式主语来取代 that 引出的主语从句的句子在形式上与强调句型几乎完全一样, 学生很难区别开来. 这些项目都是需要在教学中重点关注的. 特别是对于强调由 until 引出的时间状语(从句), 原句中的否定词在强调句中放在什么位置需要加强训练, 原因是强调句中否定词的位置与原句中的位置不同,容易造成学生在使用时的混乱.另外, 强调主语时，如果主语是人，既可以用 who
3、，也可以用 that如果强调的主 语是人称代词时，既可以用人称代词的主格，也可以用人称代词的宾格这些在教学中 都需要加以说明.V. 教学设计:根据职校生在学英语知识时不善于整体观察, 前后照应, 只顾眼前, 不及其余的弱 点, 在解决重难点中的第一个项目时, 需要引导学生学会观察和联系: 如果是句型变换, 用强调句型去强调原句中除谓语以外的某一成份, 则需要根据原句中的时态来决定是 用 is 还是用 was. 如,1. I go3It is on foot that I go to school at half past six every morning.2. I went It was o
4、n foot that I went to school yesterday.题 1 中, 原句的动词时态是一般现在时, 所以在强调句中用 is; 题 2 中, 原句的动词 时态是一般过去时, 所以在强调句中用 was.如果是客观题中的选择题或主观题中的翻译或根据汉语意思完成句子, 当涉及到项强调句型是用 is 还是用 was 时, 就需要联系到句中未被强调的部分中的时态来确定.如,1. It _ Jack who broke the window .A. be B. is C. would be D. was2. 是 Jack 打破了窗户.It _ who broke the window
5、.题 1 中, 句中未被强调的部分中的时态是过去时 broke, 所以选 D 答案; 题 2 中, “打 破了”是表示已发生的事, 句中未被强调的部分中的时态是过去时 broke, 所以, 需要用 was Jack 来完成句子.在解决重难点中的第三个项目时, 需要用演绎法引导学生从分析句子的语法功能入手去判断哪是强调句, 哪是由 it 作形式主语来取代 that引出的主语从句. 还可以用一个更简捷的方法来判断: 把句中的 “ It is / wasthat”去掉, 看剩下的部分是否能重新组4成一个完整的句子, 如果能再组成一个句子, 原句就是强调句型, 反之, 就不是强调句型. 如:It wa
6、s on the street that I met an old friend yesterday. 去掉句中的 “It wasthat”这一结构后, 剩下的部分还可再组成 “I met an old friend on the street yesterday.”这一个完整的句子, 所以原句是强调句型结构. 再如:It was a fact that he won the first prize in the game. 去掉句中的 “It wasthat”这一结构后, 剩下的部分不能再组成一个完整的句子, 所以, 原句不是强调句型, 而是由 it 作形式主语来取代 that he won
7、 the first prize in the game 这个主语从句的句型, 原句的另一形式是: That he won the first prize in the game was a fact(他在比赛中获得第一名是事实.).重难点中的第四个项目需要要求学生记住 not 在强调句中的位置来解决. 在由 until引出的时间状语(从句)的( 复合)句中, 当( 主)句中的谓语动词是短暂性动词时, (主)句子用否定式. 如果强调由 until 引出的时间状语(从句), 则 not 要放在 until 的前面. 如: Jordan didJordan 四十多岁才停止打篮球 ) 强调则句型是:
8、It was that Jordan stopped playing basketball.5I did It was that I went to bed.在解决重难点中的第二个项目时,次开发只需要加以说明就可以了, 即: 当强调的句子的主语是人称代词时, 句型中既可用 that, 也可用 who. 该人称代词既可用主格, 也可用宾格. 如:He goes to school by bike every day. It is to school by bike every day.VI. 教学步骤(One teaching period)Step 1: Presentation: What
