Eg: ruler, bicycle, umbrella, ...
Other inventions :________________________________________________________
【设计意图】：用“看”和“找”的形式引入，引起学生的兴趣，激发其求知欲。学生包括学困生都跃跃欲试。
（二）连一连，读一读：
想了解更多发明物吗，请翻到课本P68和P69，你认识它们吗？快来测试下自己吧！
1．把下面的词和图片连线：

calculator battery-operated slippers shoes with adjustable heels
2．跟读磁带，标音标译中文：（在会读的词后画上★。）
computer telephone heated ice cream scoop TV set
calculator battery-operated slippers shoes with adjustable heels
【设计意图】：用图片刺激视觉，引起学生的兴趣，帮助学生特别是学困生学会如何预习，使他们在课前解决生词的意思和读音问题，为课中学习做铺垫。
（三）说一说，比一比：
你知道这些发明物是什么时候发明的，它们被发明的先后顺序吗？试着用下面的句子和同伴说一说，比比谁的课外知识更丰富！(课堂上需要你勇敢地展示自己哦！)
When was/were the ... invented ? It was/They were invented in..., I think.
I think the...was/were invented before/after the...
你能猜出be invented的意思吗？ be invented________

【课中随堂】
（一）听一听，标一标：
通过预习，相信你已经了解到不少发明物的信息了吧，让我们来听一听，看看你的猜测是否正确。listen and match the inventions with the dates.(见课本P68，1b。)
【设计意图】：通过听力练习，巩固预习知识及课堂所学内容，为语言运用作准备。
（二）辨一辨，说一说：
1．辨词形并写出中文意思：
invent_________ invention__________ inventor_____________
你能试着用这三个词造句吗？（比比谁造的句子既准确又优美！）
invent________________________________________________________________
invention______________________________________________________________
inventor_______________________________________________________________
2．识词组并造句：
Cars were invented in 1885 and what are they used for?
你知道be used for的意思吗？你能猜出be used for后接动词的什么形式？
be used for_____sth(to do,doing,do)，你能用这个词组造句吗？
...is/are used for...________________________________________________________
(开动你的脑筋，要尽量用今天所学的发明物哦！比比谁造的句子既准确又优美！)
【设计意图】：巩固基础，强化重点，化解难点，为语言交际运用作准备。
（三）听一听，编一编：
1．听对话，标顺序：
见课本P69，2a, 2b。
2．看表格（2b），编对话：
可参照以下句型哦！（两人一组对话表演。）
-Look! What is it/are these? -It is/They are…
-When was it/were they invented? - It was / They were invented in…
-Who…? -…
-What…? -…

Jayce Coziar and Jamie Ellsworth ______shoes with adjustable heels.They are used for__________of your shoes. _____ ice cream scoop was invented by Chelsea Lanmon.

【设计意图】：把听力材料改编为一个report的形式，让学生提炼整堂课中重点词汇和句型，充分发挥听力材料的听说读写功能，同时也为拓展作业中学生自己创作做准备。
【课后巩固】
（一）口头作业：
1．跟读磁带, 1b和2a跟读磁带2遍，模仿语音语调。（明天组长处朗读，并抽取部分学生到老师处朗读。）
2．熟记本课时重点词组和句型, 你可参考下列重点内容。（明天以听写形式检查。）

2．你对哪些发明物感兴趣？以“report”的形式介绍一到两种发明物。要用到今天所学词汇和句型哦！可参照上面“读一读，填一填”。（明天先组内交换互批，要有批改痕迹，再上交。）
【设计意图】：在学生已基本掌握这个课时重点知识的前提下，以听力材料整改成的report为模板，通过“写”来落实语言点。
