Unit 2 Healthy EatingI.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。
Warming Up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True or False 第四部分通过Main idea 的寻找,使学生对文章有了一个浅层的理解.Learning about Language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ought to等的基本用法。
Using Language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。

激发学生的阅读兴趣,为本单元Reading部分的世界节日做好铺垫。

同时以习题形式预习新课。
三、知识讲解考点/易错点1 重点单词与短语学习mean n.意义,意思v. 意味;想要(回归课本P1)Festivals are meant to celebrate important times of year.[归纳拓展]mean to do 打算做某事be meant to do 被要求做…mean doing 意味着….eg. I never meant him to work for us.Passing the entrance examination means being admitted into college.take place发生(回归课本P1)Discuss when they take place, what they celebrate and what people do at that time. [归纳拓展] take place/happen/occur/break out/come about(1)take place 其“发生”是按意图或计划进行,无偶然性,无被动语态。
(2)happen “发生”,常指具体客观事物或情况的发生,含有“偶然”的意味。
当以具体事物、事件作主语时,happen 和occur 可以换用;但当happen用作“碰巧”之意时,不能用occur代替,但可以与come about 互换。
用法是happen to do sth.,无被动语态。
(3)occur发生,出现, 较正式用语,可指事情偶然地、意外地发生或思想突然浮在心头。
occur to 有“想起”的意思。
指具体事物时可与happen互换(但happen to do不可换成occur to do);另外occur 有“突然想起”的意思,此时不可与happen 互换,如A good idea occurred to him.(4)break out (战争、火灾等)爆发;(疾病)突然发生。
