教案Book3Unit2HealthyEating

I.教学内容分析

本单元的中心话题是健康饮食。

主要是为了使学生对与健康有关的问题得到更好的理解。

这一单元鼓励学生去检查自己的饮食行为,看一看它是不是健康的饮食习惯。

一种健康的饮食习惯应该是平衡的,既不在脂肪、糖和盐这些方面过剩,又不会在人体必需的营养元素方面匮乏。

通过本单元的学习,学生可以对健康饮食有一个清楚的概念,从而根据所学的知识去思考与健康有关的问题。

WarmingUp部分通过问题向学生询问饮食构成,让学生对本单元的内容能有一个初步的了解,并使学生复习与有关饮食的单词和短语。

然后让学生回答一组问题,通过这些问题的讨论,引导学生参与表达自己的看法,激发学生兴趣和好奇心,让学生自然而然地进入下一部分的学习。

Pre-reading部分通过几个问题讨论,让学生认识平衡营养的重要性,为课文的学习做出铺垫。

Reading部分主要讲述了王鹏和咏慧开饭店的故事,借此揭示了不同食物对人体有着不同的影响。

故事讲诉了王鹏和咏慧两家饭店的两种饮食都是不合理的,经常去王鹏的饭店容易发胖,这样会导致高血压和心脏病等疾病;而经常去咏慧的饭店的顾客则容易变瘦,这样容易导致厌食或是营养不良,让学生注意并避免走这两种极端。

这些距离学生自身生活很接近的问题很容易引起学生的思考。

在教授的过程中注意积极的引导学生不断的进行反思。

Comprehending第一部分通过TrueorFalse第四部分通过Mainidea的寻找,使学生对文章有了一个浅层的理解。

LearningaboutLanguage部分突出了词汇和语法的学习与训练。

本单元的语法是情态动词oughtto等的基本用法。

UsingLanguage部分中包括了听、说、读、写几个部分的内容。

学生可通过王鹏和咏慧的这一个事情,深入展开讨论与健康饮食有关的事情。

阅读后的习题及讨论不仅帮助学生加深对文章主旨大意的理解,更重要的是让学生学会用所学的知识,解决在现实生活中遇到的问题。

LearningTip部分主要建议学生学会通过学到的与健康饮食有关的内容,安排合理的膳食;让学生通过查询各种资料,熟悉各种饮食习惯、饮食结构与饮食文化,不断开拓自己的视野。

Step4Grammar

Purpose:

TogetSstohaveknowledgeofthisgrammarpoint:

oughtto

1.ExplainforSsthegrammarpoint.

ought是情态动词,与to连接构成情态动词词组。

ought无人称和时态变化,可用于现在时以及将来时,用于过去时则位于动词过去式之后或不定式的完成式之前。

ought可以表示“义务”、“要求”或“劝告”,常译作“应该”、“应当”等(和should差不多,只是语气稍差一些);有时表示“非常可能”的意思,否定式为oughtnotto(oughtn’tto),疑问句式为OughtI/youto……?

Ioughttowritetohimtoday/tomorrow.我今天/明天应该给他写封信。

IknewIoughttowritetohim.我那时知道我应该给他写封信。

ShesaidIoughttowrite.她说我应该写。

Iknow/knewthatIoughttohavewritten.我知道/那时知道我该写的。

ought与带to的不定式连用。

为了提醒学生这一点,常称之为oughtto。

问句或话语中用oughtto的时候,可以用should来回答;用should的问句或话语也可以用oughtto回答:

—Yououghttoputincentralheating.—你应该装上暖气。

—Yes,IsupposeIshould.—是的,我应该装。
