英语教案－When was it built?

　　第40课有一个要求学生仿照范例写一篇短文的练习。在写的练习前，特意设计了Ask and answer 的练习。练习中的8个问题存在着内容上的联系，含有“信息沟”，学生们通过问答来获取完成笔头练习所必需的信息。因为笔头练习的内容和所需运用的语言结构都与本单元前几课紧密相关。所以在充分学好前几课的基础下写好这篇短文并不困难。

　　教师在呈现这8个问题时，可使用投影片。教师说物品的名词，如：a watch，然后要求学生回答问题。每次呈现投影片中的l道问题，遮住其他问题。学生先口头回答1-2组问题，并分别将这些问题的回答口头串成一篇短文。教师可提供一些词语，如： metal, glass, cotton, street marker, shop等。在学生口头练习基本熟练的情况下，再要求他们笔头完成课堂

　　练习。教师亦可将范文作为听写练习的材料。在课本提供的8个物品名词中，必会词为：watch, radio, computer其余可作为学生了解的词语。

教学建议

关于一般过去时被动语态的教学建议

　　本单元的语法重点是一般过去时被动语态。第9单元已经教学了一般现在时被动语态，所以本单元语法教学应将复习与教新课相结合。

　　教师先依次出示画有cotton, jacket, wool, coats, thermos图案的卡片，复习一般现在时的被动语态，引出下列对话：

　　1. T: Whats this?

　　Ss: Its cotton.

　　T: Wheres cotton grown?

　　Ss: Its grown in....

　　2. T: Is this a jacket?

　　Ss: Yes, it is.

　　T: Whats it made of?

　　Ss: I think its made of cotton.

　　3. T: Whats this?

　　Ss: Its wool.

　　T: Wheres it produced?

　　Ss: Its produced in/at . . ..

　　T: Whats (the) wool used for?

　　Ss: Its used for making sweaters or coats.

　　T: Look at these coats. Theyre made of wool.

　　4. T: Whats this?

　　Ss: It’s thermos.

　　T: Whats it made of?

　　Ss: The inside is made of glass and the outside is made of metal.（教师给予适当的提示）

　　T: Whats it used for?

　　Ss: Its used for keeping water hot.

　　为了降低难度，第4段对话也可先让学生仿照前三段对话来提问，教师来回答。然后交换。还可以在适当的时间让学生做group 或pair的连锁问答。

　　然后教师让学生阅读第38课。在阅读前，设置一些问题，使学生们带着问题有目的地进行快速阅读。

　　T: Now we are going to read a passage about a group of girls visiting a museum. After reading, youll have to tell me what the girls saw in the museum?

　　阅读完毕，教师将有关问题和学生们的回答板书在黑板上，一般过去时被动语态中was和were要彩笔标出。然后进行问答练习。

　　学生再次阅读第66课，要求他们找出上面对话练习中未涉及到的被动语态句子。如：

　　They were very interested in dinosaurs.

　　So these eggs were laid long long ago by dinosaurs!

　　It was discovered in Liaoning Province.

　　教师引导学生分析课文中哪些句子可改写成一般过去时被动语态。如：

　　Miss Li showed them a picture of the feathered dinosaur. →

　　They were showed a picture of the feathered dinosaur by Miss Li.

　　A picture of the feathered dinosaur was showed to them by Miss Li.
