根据前一天的单元目标,设计这一Unit 或者Module的词汇(或语法)教学的目标和词汇(或语法)教学方法。
名词性从句教学
一.教学目标
知识目标:掌握名词性从句中关系代词和关系副词的作用和功能,能准确选择名词性从句所需的关系代词或关系副词。
能力目标:能较好地运用名词性从句,能正确区分主语,宾语,标语,同谓语从句。
情感目标:通过学习调动学习积极性,使学生体会到英语的趣味和实用性。
二、重点难点:提高学生对语法学习的兴趣和积极性,较好地掌握名词性从句的用法,理解名词性从句的概念,运用知识点解题。
三、学情分析
语法向来是学生头痛的一项内容,而名词性从句在历来的高考试题中都有所体现,因此,掌握这一内容显得尤其重要。我所教的班级学生为普通生,英语的基础比较差,再加上语法复习基本以呈现理论为主再辅以练习,相对枯燥,学生兴趣不够,容易分散注意力,所以应溶入一些新的教学元素。这个年龄的学生争强好胜,喜欢新事物,于是我考虑借用大家感兴趣的话题通过竞争法等促进学生的热情,增强学习的效果。
四、教学方法
以学生为主体,尝试创新思维,联系社会采用讨论、协作、探究、竞争的教学模式,引导学生灵活运用所学语法知识。
五、课前准备
1、布置学生熟记名词性从句各关系代词和关系副词的用法。
2、教师准备相关多媒体课件。
六、教学课时:一课时
七、教学过程
I.lead-in 复习导入 II.presentation 一)定义和分类
把一个句子当做名词使用(用来做主语、动词宾语、表语、同位语、介词宾语),这个句子就叫名词性从句;当做什么来用,就叫什么从句。
二)引导词不充当任何成分的连词(5个)that(无任何词意)
whether,if(均表示“是否”表明从句内容的不确定性)
as if ,as though(均表示“好像”,“似乎”)2 充当成分的连接代词(9个)
what, whatever, who, whoever, whom, whomever, whose, which, whichever 充当成分的连接副词(7个)
when, where, how, why, whenever, wherever, however
三)特殊情况
It 做形式主语,形式宾语时,真正的主语从句,宾语从句放在后面。
四)注意事项
不可省略的连词:
1.介词后的连词
2.引导主语从句和同位语从句的连词不可省略。
例1 That she was chosen made us very happy.(主语从句,that不可省)
例2 We heard the news that our team had won.(同位语从句,that不可省)
3.同学们要特别注意同位语从句与定语从句的区别。(1)同位语从句的作用是对前面的词进行具体的说明。(2)定语从句的作用是对前面的词进行修饰或补充。
(3)尤其要注意that 在这两种从句中的用法,that在同位语从句中不作成分无意思,that在定语从句中要做成分有意思。
五)做题技巧
同学们首先要知道基本上我们所学的所有特殊疑问词都可以引导同位语从句,还有就是要记住that,whether,if,as if,as though 这几个词也可以。
做题的时候,把选项当中的词直接代入句子中,哪个翻译得通就选哪个,当然也要注意是不是特殊的句式(It做形式主语,形式宾语;同位语从句)
III.production 六)练习巩固
我讲完这些之后就给学生发一些打印的名词性从句练习题让他们做。我一般会先讲解几个,其他的让他们自己按照我们上面说的去做。1.________that they found an unusual plant in the forest.A.It is said B.They are said C.It said D.It says
