必修2Uint4被动语态的构成和用法[学案]主动语态指主语是谓语动作的使动方。
也就是说谓语的动作源自主语,而施加于宾语。
相反,被动语态中,主语是谓语动作的受动方,如果有宾语的,宾语往往是谓语动作的使动方。
在语法机构上,主动语态和被动语态的区别主要在于,主动语态直接使用动词原形作为谓语,然后再在该动词原形的基础上施加时态和其他语法;而被动语态则使用系词+动词的过去分词作为谓语,各种时态和其他语法也施加在系词上。
举例:主动:The snowslide killed him.被动:He was killed by the snowslide.意义均为:他死于雪崩。
英语中的被动语态使用得比汉语要多,要普遍,许多课本乃至实际应用中都常常涉及到这个问题。
一般说来,当强调动作承受者,不必说出执行者或含糊不清的执行者时,多用被动式。
须注意的是,许多地方与汉语不同。
注意那些汉语中没有"被……"的意思,英语却用被动态。
还要注意,英语的被动态往往由"by"引出,而有用介词"by"的短语往往又不是被动态,而是系表结构。
还有些待殊现象,如…known to man(人类......所知),on foot步行(美国人有时用by foot),in carraige(乘四轮马车)等等。
还有假主动,真被动的十几个常用词的用法,以及so heavy to carry而不用so heavy to be carried等习惯用法。
有关这类情况,做到心中有数对全面掌握被动态,准确无误地解答习题非常关键,被动态必须涉及的是动词的各种时态变化的问题。
英语的时态本来很复杂,怎样记住各自的被动形式呢? 首先要明确"将来进行无被动,现在完成进行同"。
这两种时态无被动形式。
另外,不及物动词带有同源宾语的动词,反身代词的动词和系动词都无被动形式。
即便如此,还有不定式,动名词,分词,以及它们的复合结构)的被动态,再加上情态动词,助动词以及它们的疑问式和否定式从中掺杂,真是令人头痛,眼花缭乱。

高中英语必修二U4 Wildlife protection教学设计1.整体设计思路、指导依据说明本节课体现的是《普通高中英语课程标准》规定的课程性质和理念:“使学生在义务教育阶段英语学习的基础上,进一步明确英语学习的目的,发展自主学习和合作学习的精神;在加强对学生综合语言运用能力培养的同时,注重学生用英语获取信息、处理信息、分析问题和解决问题的能力以及用英语进行思维和表达的能力。
”本节课以新课程标准的一些核心理念为依据,以任务型语言教学为主,通过实际生活中的真实语境,激发学生学习英语的兴趣,寓教于乐,倡导小组表演活动,小组讨论,鼓励学生全体参与课堂,在体验、实践、合作与交流的学习方式中,培养学生用英语表达的能力,理解保护野生动物的重要性,达到培养学生的社会责任感,提高思考和判断的能力,进而增进跨文化理解和跨文化交际意识。
本节课的设计重视课前的导入,重视课中学生的小组角色表演。
2. 教学背景分析教学内容分析:本节课必修二第四单元 Wildlife protection 的 Reading 部分。
本单元的话题“野生动物保护” 。
Reading 是整个单元的核心部分,是Warming up 的延续和升华。
此外,大部分的重要词汇和句型结构都在这个课时中呈现出来。
完成本节课的阅读,为本单元目标的完成作了很好的铺垫。
也是培养学生阅读能力的重要渠道,发展阅读技能和策略的必经之路。
文章介绍了一个叫Daisy 的小女孩在梦中经历的一次奇妙的飞毯飞行。
通过女孩和藏羚羊、非洲象、猴子的对话,学生进一步意识到野生动物的生存环境日益恶化以及保护野生动物的行动刻不容缓。
学生情况分析:教学对象为高一学生,所教班级的学生思维活跃,有强烈的求知欲望,认知能力比初中有了进一步的发展,到了高中逐渐形成用英语获取信息、处理信息、分析问题和解决问题的能力,具备一定的阅读理解能力,不再单纯地满足教科书上仅有的知识,有获取更多信息的欲望。
笔者注重提高学生用英语进行思维和表达的能力。
Unit 4 Wildlife Protection 说课(NSEFC Book 2 Unit 4 Wildlife Protection)大家好,今天我要介绍的课是普通高中课程标准实验教科书英语必修2第4单元Wildlife Protection的阅读部分。
下面我将从以下四个方面阐述我的课:教材分析、学情分析、教学方法、教学步骤和板书设计。
一、教材分析:(教材内容分析,教学目标, 教学重点和难点)首先,我来讲下我的教材分析。
这主要包括教材内容分析,学情分析,教学目标和教学重点和难点四个方面。
1. 教材内容分析这篇阅读材料紧扣本单元的中心话题“野生动物保护的重要性”,讲述了一个叫戴西的小女孩在梦里和一些野生濒临灭绝的动物交谈,知道了保护野生动物的重要性,既是对前面热身部分的升华,也是这单元的主题内容和词汇学习的重点。
这篇文章结构十分清晰,是按戴西在梦中的的三次飞毯经历来分段的,但段落大意不是很明确。
此外,在这篇文章中出现的生词不是很多。
(下面,我来讲下对学生学情的分析)2. 学情分析学生对本单元的主题“野生动物保护”的话题是十分的熟悉,而且学生们对各种各样的动物也十分的感兴趣。
高一现阶段的学生也已经掌握了基本的像寻读,略读,概括等阅读技能,他们也能就一些问题进行英语对话讨论。
但是,学生对文中出现的组织WWF并不清楚,对有些句子所隐含的话外之音也不是很清楚,也对独立解决一些现实的问题感到困难。
3. 教学目标本节课的教学目标包括知识目标、语言技能目标、情感目标、文化意识和学习策略目标。
语言技能:1)学生能够应用不同的阅读技能得到所需的信息;2)在略读后,学生能概括各段段落大意;3)学生能够分析作者某些句子的写作意图,像“No rainforest, no animals, no drugs” and “And there are always WWF.”语言知识:1)学生能知道更多的关于为什么一些动物濒临灭绝以及如何保护它们;2)通过学习大部分学生能够掌握并运用重要词汇: mercy, importance, contain 等等;情感态度:学生能够认识到保护野生动物的重要性;文化意识:学生能对WWF组织有一定的了解。
