课文分析

结构：可分为四段：

Part 1 ( Paragraph I ) The number of milu deer in nature parks in China is increasing every year.

Part 2 (Paragraphs 2-3) The history of milu deer in China and in England

　　　(Paragraph 2) The milu deer disappeared during the Ming and the Qing periods.

　　　(Paragraph 3) The only milu deer alive belonged to the Duke of Bedford in England.

Part 3 (Paragraphs 4-5) The milu deer centers in China

　　　(Paragraph 4) The life of milu is being studied in the Naniaizi Milu Park.

　　　(Paragraph 5) The number of milu deer has greatly increased in Dafeng.

Part 4 ( Paragraph 6) It's hoped that there will be milu deer living in the wild in China.

语言点：本课文有两个要点，值得注意：

　　1．It’s hoped….that (人们希望)是个常用句型，其中的it是形式主语，that引导的是个主语从句。类似的有It is said /reported/believed/ that…..等

　　2．There are so many deer that some are being sent to nature reserves by environmentalists who would like to return them to the wild.其实，现在这种麋鹿已经相当多了，有一些正在被送往那些愿意把麋鹿送回野外去的地方。

　　1）该句是一个较为复杂的复合句，主句为…there are so many deer, that引导的是结果状语从句。

　　在这个so……that结构中，中心词是名词deer，本应该用such…that结构，但因名词前有many修饰而用了so……that结构，此特殊用法需注意。

　　are being sent是现在进行时的被动语态形式，表示“正在被送往”。

对话建议

1．建议在未讲课前，教师为了导入新课，可对学生进行以下的提问：

课文建议

1．建议教师把有关本课文有关the milu deer的背景知识介绍给学生，使学生先有一些了解和认识。

2．在未讲课之前，让学生大声的对这篇课文进行朗读，教师可把课文的一些问题写在黑板上，达到一边朗读一边思考问题。

3．教师结合课文的内容，可有图表或者数据形式，对the milu deer 用过去，现在及将来三种形式分析给学生，这样加深对课文的理解和生动。

4．教师最后总结课文的知识点，了解学生的掌握情况。

词汇辨析

common, general, ordinary和usual

可作“普通的”“平常的”但有所差异。

common侧重“普通”，表示“时时发生，人所共有”，并含有“并不高贵，地位低下”之意味，其反义词为rare。

general侧重“普遍”之意，表示在大多数我或事物中流行并受到关注，不含有“地位低下”之意，其反义词为specific。

ordinary与common基本同义，侧重“平凡的，普通的”，表示“随时可以碰到，不值得惊奇”，其反义词是superior。

usual用来指事物，意为“通常的，惯常的”，含有“随集体风俗或个人习惯而常常发生”之意，其反义词为unusual。举例如下：
