1、微课教案 it用于强调句式太和中学：袁晓娟1it强调结构的概述it用在强调结构中，为了强调句子的某一成分(通常为强调主语、宾语和状语)。结构为:“It is/was被强调部分 that句子的其余部分”。（首先对强调句的概述，让学生对此概念有个初步的了解。同时列出强调句式的结构，让学生很直观的看到强调句式的特点。）2it在强调句中的应用(1)强调主语I met Tom in the street last week.It was I that met Tom in the street last week.正是我上周在大街上遇到了汤姆。(2) 强调宾语I met Tom in the stree
2、t last week.It was Tom that I met in the street last week.我上周在街道上见到的是汤姆。(3) 强调状语I met Tom in the street last week.It was in the street that I met him last week.我上周是在街道上见到她的。I met Tom in the street last week.It was last week that I met him in the street .我是上周在街道上见到她的。（一一列出强调句式所强调的成分，让学生从细节上了解强调句式。并通过
3、对强调句的汉语翻译，让学生体会到了强调句的特点以及对句子成分强调的重要性。）3. 如何判断强调句式It was I that met Tom in the street last week.It was in the street that I met him last week.注：去掉it is/was与that，剩余部分若结构完整、句意明确，则为强调句型，否则不是。It was obvious that he was right.注： 这句话就不能称为强调句式，因为去掉it is/was与that，剩余部分结构并不完整。(通过对强调句式的判断，让学生了解到并不是It is/was.tha
4、t.句型都是强调句，所以让学生在做题时提高判断强调句式的警惕性。）4 it强调结构的疑问句(1)强调句的一般疑问句:只需要is/was提前。Was it you that broke the window?Is it Professor Wang who teaches you English?(2)强调句的特殊疑问句：只需在一般疑问句前加上疑问词就可。Who was it that broke the window?When was it that you called me yesterday?(通过对强调句一般疑问句和特殊疑问句讲解，让学生通过类比的方式，把握强调句疑问句的特点。）5.用
5、这一强调句型时，还要注意以下几点:(1)强调时间、地点、原因或方式状语时，要用that,不能用when,where,why或how。It was in the street that I met him last week.It was last week that I met him in the street .(让学生再次加深对强调句It is/was.that结构的理解.)(2)强调句型一般只用that，但被强调的是人时，且做主语，可用who取代that；被强调的是人且作宾语时，也可用whom代替that/who。It was I that/who met Tom in the str
6、eet last week.It was Tom that/who/whom I met in the street last week.(扩大了对强调句It is/was.that结构的理解，再次强调that功能很多，人物均可；who既可以作主语，也可以作宾语；whom只作宾语。）(3)如果强调的是主语时，that或who之后的谓语的人称和数要与被强调的主语保持一致。It is only I who/that am willing to go to the cinema.It is he who/that is to blame.(主谓一致在语法填空和改错题中是常考点，所以在强调句式中要让学
7、生特别注意这一考点）(4)强调句型中的it不能更换为其他代词；is/was数的形式不受被强调部分单复数的影响。It is jazz that I like most.It is his novels that I like most.(让学生打破常规思维，再次让学生铭刻强调句式的结构：It is/was.that.）(5)使用这一强调句型时，需注意否定转移 Money cant buy everything.It is not everything that money can buy.钱不能买到一切。 He didnt go to bed until ten oclock last nigh
8、t.It was not until ten oclock last night that he went to bed. 昨晚他12点才去睡觉。注：由于not已经前移，that 后只能用肯定形式。（在强调句式中，若有否定词not，通常把否定词not提前，这是加强强调句式意义的体现。所以，that之后只能用肯定形式。）(6)强调句型的时态要依原句的时态而定，即原句为过去的某种时态，强调句中就用 was ；原句为现在或将来的某种时态，强调句中就用 is。I met Tom in the street last week.It was I that met Tom in the street last week.He is to blame.It is he who/that is to blame.(通过对时态的强调，这就提醒学生要注意原句中谓语动词的时态） 教案
