高中英语虚拟语气教案

精品文档
㈠课程说明
教学目标：
虚拟语气是高考的重点，且难度较大。本次课程通过对虚拟语气知识点的复习讲解，总结概括，让学生知道虚拟语气是用来表示人的主观的愿望和假想，达到学生对知识点的熟练运用，在脑海中形成具有条理性的知识框架的目的。
教材分析：
虚拟语气是高考英语重点和难点，掌握好虚拟语气的重要性对每个参加高考的学生不言而喻。这次课程是高三第一轮复习时对虚拟语气的再次讲解和梳理，全部的知识都经过了高度的总结合概括，均是高考考点。
学生特征分析：
辅导的学生是高三年级，刻苦努力，理解能力较强，有一定的基础。基本知识掌握一般，且很多重要的知识点已经遗忘。
教学重点难点：
1、 真实条件句和非真实条件句的用法。
2、 虚拟语气用在主语从句，表语从句，同位语从句，定语从句中的用法。
3、 情态动词+ have + done的用法。
㈡课前准备：
教学方法：
一对一辅导，面对面答疑，培养学生对英语的理解表达和思维的能力，同时安排适当的练习，保证学生能够当堂消化所讲内容。
教学器材：
黑板，粉笔，草稿纸，教案，给学生的资料，如果有条件可以适当运用多媒体。
时间分配：
讲课40分钟，做练习题20分钟。
㈢课程设计：
一、导入：
If you were to succeed, everything would be all right.
If you had asked him yesterday, you would know what to do now.
（这两个句子是什么形式？之前学过还有印象吗？通过提问问题激发学生的思考能力，再次对学生的知识掌握能力进行了解。）
二、讲解虚拟语气基本知识
Ⅰ 什么是虚拟语气？
虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测，建议等含义。虚拟语气所表示的含义不是客观存在的事实。
Ⅱ 虚拟语气在真实条件句非真实条件句中
真实条件句：表示现实或可能变为现实的条件。
非真实条件句：表示非现实的，或不可能，或不大可能变为现实的条件。
（老师举例说明真实条件句和非真实条件句。）
Ⅲ 列表记忆
由于虚拟语气的知识点杂乱，通过列表能够较轻松的记忆，在黑板上画图，并且让学生当堂记忆。

虚 拟 条 件 句
主 句
与现在事实相反
动词过去式（be动词用were）
should/would/could/might + do
与过去事实相反
Ha + done
should/would/could/might + have + done
与将来事实相反
①动词过去式
②should + do
③were to + do
should/would/could/might +do

（在给学生一段记忆时间后，让学生运用虚拟语气造句，保证学生已经对所讲内容消化吸收。）
三、讲解重点内容和特殊情况
Ⅰ 什么情况下省略if？
Ⅱ 什么是错综时间条件句？
Ⅲ 什么是含蓄条件句？
Ⅳ if only条件句的用法
（此部分不要求学生掌握过多，因此在讲解之后给出题目，要求学生在课后巩固复习。）
四、虚拟语气在从句中怎样用？
Ⅰ 如何用于宾语从句中？
1、 wish
2、 demand, order, require, insist, suggest, propose, advise等。宾语从句的虚拟语气结构为：should + do
3、would rather
Ⅱ 如何用于主语从句中？
It is proposed/necessary/important/strange/natural /desired + that从句
It is a pity/a shame/no wonder + that从句
Ⅲ 如何用于表语从句和同位语从句中？
在名词 advice, order, suggestion, request, proposal, plan, idea等后边that引导的同位语从句，或这些名词作 主语时后面that引导的表语从句中，虚拟语气结构为：should + do
Ⅳ 如何用于定语从句中？
It is high time + that从句，从句谓语形式用过去式，或should + do(should不可省略)。
Ⅴ as if/as though用在虚拟语气中。
as if/as though引导表语从句与方式状语从句皆可。
谓语形式：过去式（从句动作与主句动作同时发生）
had done（从句动作先于主句动作）
could/would/might + do（从句动作后于主句动作）
Ⅵ 情态动词+ have + done怎样用？
1、must have done
2、can/could have done
3、can’t/couldn’t have done
4、may/might have done
5、should/ought to have done
6、shouldn’t/ought not to have done
7、needn’t have done
8、had better have done
9、would rather have done
10、would like/love to have done sth
（由于此部分难度较大，且知识体系庞杂。因此在讲过之后就给出例句和习题，让学生当堂做出，并且进行辅导讲解，让学生运用更加灵活。）
教师活动：
在课程设计里，教师通过讲解知识，让学生更加轻松的记忆知识点，梳理学生的知识结构。在学生掌握之后辅导学生做题。
设计理念：
由于学生处在高三这一特殊阶段，学习能力和理解能力相比较于高一高二已经有了一个较大的提高，且知识已经学过一遍，因此教师要保证学生在听过课程之后对知识能够熟练运用和掌握，且能对此有深刻的记忆。
㈣教学反思：
高三的特殊性决定了学生在学习英语时无法进行口语或者听力的练习，同时由于没有学习英语的环境，使得学生在学习英语的时候只能一味的做题，背课文，理解语法等。而老师也只能进行填鸭式的教育，这样大部分学生在学习英语的时候就会失掉很多乐趣，可能会导致一些学生对英语产生反感和厌恶的心理，不利于学生的长远发展。
