Grammar教案2

虚拟语气 教学设计 高三复习课

总1课时

执教者：李克梅 第10周 第四课时 2018年4月20日星期五

教材分析

《高中英语课程标准》分析，虚拟语气这一语法项目是各类英语考试中心测试的重点之一，在高考题型中都有可能会涉及到。它的结构和用法比较复杂，是高中阶段英语学习的一个重点和难点，也是高考英语常考的一个考点，掌握好虚拟语气对于语言理解和运用也具有重要的意义。根据英语课程标准的具体要求和今年考纲要求，对于虚拟语气应该掌握以下内容: 1、虚拟语气的语法规则

2、虚拟语气在if非真实条件句中的应用

3、条件句中虚拟语气的倒装

4、名词性从句中虚拟语气的用法

5、几种特殊结构中虚拟语气的用法,如:if only ,wish ,as if/though ,would rather等

学情分析

因我校英语实行走班教学，把学生分成了AB两个层次。A层为基础薄弱一些的，B层为基础较好的。对于A层的学生来说，英语基础差语法知识混乱，即便是高三学生了，对于虚拟语气的理解和使用还是茫然的。有些即便能够理解虚拟语气的概念和意义，但在实际的做题和理解识别时却常常张冠李戴，不能准确运用精确理解句意，所以说到虚拟语气,学生是不知所措，更谈不上兴趣了。因此我根据我所教班级学生的实际情况，本着激发学生的兴趣,变被动学习为主动学习，让语法知识从易到难，循序渐进。

教学目标

【知识目标】：掌握虚拟语气语法的基本规则。

【能力目标】：能解决有关虚拟语气的习题，并在设定的情景下能够运用该语法项目进行流利的交际和观点的表达。

【情感目标】：通过师生在教学的双边活动中主动性和创造性的发挥，激发学生的学习兴趣,体验知识间的相互应用，相互依存联系，让学生充满自信，体验成就感和合作精神，从而对高考充满信心。

教学重点

掌握虚拟语气语法的基本规则

教学难点

运用语法规则去完成各种习题，并在实际语言运用中去灵活应用，培养学生的语言运用能力和英语思维。

教学方法

为了突出重点，突破难点，完成教学目标，选择行之有效的教学方法是非常关键的。根据课程标准的要求和本节课的特点，我主要采用合作探究、归纳总结、对比演绎和训练巩固法。倡导自主-合作-探究的学习方式。关注学生的个体差异和不同的学习需求，爱护学学生的好奇心、求知欲。这样既充分调动学生学习的积极性，又培养学生

的观察、分析和思维能力还有创新意识。在教学过程中我注意渗透学生的学法指导，

让学生对知识进行对比分析，求异存同，在语境中学会脱繁为简以及排除法和选择法相结合。同时运用上多媒体和板书相结合的教学手段。为了完成本节课的教学目标，我是这样安排教学过程的：

教学过程

Step I Warming-up（通过这一环节，调动学生学习兴趣）

Watch a skit(滑稽短剧)---101st proposal第101次求婚

Write down as many sentences as you can. 通过导入环节，让学生在欣赏英文滑稽短片的同时，进一步调动了学生的学习热情，将枯燥的内容变得具有生气，使学生乐于去学习。让他们了解了语言知识的内容。并通过自己的分析理解推断，总结出规则。通过此环节的导入，能够让学生回忆起从前所学习的语法内容和语言知识，激活已有的知识信息，引起学生的学习兴趣，为本课的学习奠定了良好的基础。

Step II Revision（通过这一环节，让学生归纳总结所学知识）

小组活动：分小组总结虚拟语气的基本用法，并通过一定练习来检测学生对此项语法的理解和掌握情况，并设计符合学生学习实际的语言实践活动，让学生在实践中总结复习其用法，同时提高小组合作能力。

一、

if引导的虚拟条件句

与现在相反If+ 主+___________,主+ would\should\could\might...+________________.

与过去相反If+ 主+___________,主+ would\should\could\might...+________________. 与将来相反If+ 主+___________,主+ would\should\could\might...+________________. [拓展] :

虚拟条件句应注意以下几点：

1.提前were, had, should,省略if。

If I were to meet him tomorrow, I should ask him about it.

______________________________________________ 2.错综虚拟条件句，注意主从句谓语形式。

If you had followed my advice, you ___________(be) able to finish the work now. 3.含蓄虚拟条件句，即有时假设的情况并不以条件从句表示出来，而是通过一个介词

来表示如but for，

without，

otherwise，or等表示含蓄的虚拟。

(1) _________his help=_______________, we wouldn't have succeeded.(与过去相反)

(2) __________water or air=______________________, we would die.(与现在相反)

二、“建议、命令、要求、坚持”名从的虚拟

1．表示建议的动词advise, suggest, propose, recommend 2．表示命令的动词command, order 3．表示要求的动词ask, urge, require, request, demand, desire 4．表坚持的动词insist

(1)Miss Li suggests that we______________ study hard. (

)

(2)Her suggestion is that we______________ study hard. (

)

(3)Her suggestion that we______________ study hard is reasonable.（

）

(4)It is suggested that we______________ study hard.（

）

(5)The survey suggests that 99% of the students ___________ (like) English.

[小结]：_________________________________________________________________ [注意]：_________________________________________________________________ [拓展]：主语从句中的虚拟语气——用“should+动词原形”来表示

（1）It is +n. ( a pity, a shame, an honor, a surprise, no wonder…)+ that…

It was a pity that you ________

(be) so careless. （2）

It is +adj.( important, necessary, essential , impossible, natural…)+ that …

It is important that the meeting___________(hold)as soon as possible. 三、as if/though 引导方式状语从句的虚拟

现在：did /were

——He speaks as if he ______(be)an American.

过去：had done——He spoke as if he___________(be) to the USA before.

将来

: would+动词原形——He speaks as if he___________(go) to the USA tomorrow.

四、wish宾从的虚拟

主语+wish+ that+ 主语

+

(1) 现在：did /were(现在)----I wish I________(be)you.

(2) 过去：had done(过去)----I wish I ____________(meet)you last year.

(3) 将来

: would+动词原形(将来)---- I wish you _________(succeed)this time.

五、would rather 宾从的虚拟

主语+

would rather + that+ 主语+

(1)现在/将来：did /were(现在)

——I would rather you _______(stay)here.

I would rather he _______(come) tomorrow. (2)过去：had done(过去)

——I would rather you________ (not tell)him the news.

I would rather___________ (not tell) him the news.

六、if only的虚拟

(1)现在：did /were(现在)

——If only you ___________(listen)to me .

(2)过去：had done(过去)

——If only you__________ (listen) to me . 七、特殊句式中的虚拟

It is (high) time that sb. did /should do sth. “该做某事了” It’s high time that you _________________(study) hard. It’s high time that you _________________(study) hard. 八、May +主语+动词原形，表示祝愿。

May you ___________(succeed). [拓展]：情态动词+have done

(1)You ____________________(finish) your homework. (2)You look sleepy. You ___________________(stay) up late last night. 通过此环节，小组间共同总结了本节课所复习的语法知识，并让学生能够认识到该语法知识的重要性，在今后的学习语言学习和生活中不断学习，勤于应用，以促进对其的理解和掌握。小组共合作学习能够避免教师的个人总结对于学生的灌输性的讲解所带来的不利影响，让学生学会自学，培养自主探究的能力。
