Read the stories aloud and check the pronunciation to ea
29、ch other. Then try to tell these stories to your partners.(设计意图：在学生记忆本单元单词的基础上，再学习由本单元的生词编成的一篇文章， 体现了词不离句的教学原则，有助于学生学习理解和使用本单元的词汇,让学生学习单词有了语境，在语境中了解词汇的意义和词汇的表意功能，这为学生学习、实践和运用英语创造了条件，有助于学生有效记忆和使用英语词汇。通过找主题句、生生互译短文、互读短文等形式对单词进行强化巩固理解。 ）Step 5 Retell the story .T: I can see you have understood the stor

Reusable 7. laws 8. turn off【亮点】1. 本教案按照“生本教育”的理念进行备课，强化学生自主学习的理念。教学的每一步都让学生自
40、己进行学习，教师仅作指导和解决学生疑难的引路者。2.单词的拼读注重了学生自学能力和小组合作能力的培养。首先要求学生进行自读，然后读给同伴听，再读给全班同学听，老师予以纠正。为保证发音的纯正，让学生分组朗读，再跟着磁带读，最后相互纠正发音，直到所有的学生都能正确读音。3.故事的编写独具匠心，它几乎囊括了本单元所有的单词，利用一个小故事，学习了本单元的所有单词，使学生在语境中更好地链接并记忆单词，体现了“词不离句，句不离篇”的教学理念。同时将情感教育渗透其中，让学生在潜移默化中受到教育。4.同时通过各种形式的单词记忆既加深了单词的识记，又学会了部分单词的用法，渗透了本单元的重点话题，达到了预习的目的。当堂检测题也是遵循了“由易到难”的原则进行编写，使各个层次的学生都能学有所获。【不足之处】一节课的时间毕竟有限，不能面面俱到，要求学生当堂复述有难度，还需在以后的复习中查缺补漏和加大检查的广度。【使用建议】本节课容量大，词汇较多，为保证教学目标的顺利达成，需要提前安排学生进行充分的预习，至少通读词汇，能根据音标认读单词。必须提前准备课件及相应学案，让学生有本可依。复述环节优生可当堂完成，允许后进生第二天晨读后完成。
