Unit 12 Beautiful butterflies课时教案

课 题

4A Unit 12 课型

新授

根据本单元wonderland、farmland、Grand Theatre 三个板块不同的教学内容和要求，每个板块的话题都紧扣主题，但又有侧重点与联系，设计本单元主题为Insects around us, Wonderland的话题为Visitors in the garden，Farmland的话题为An interesting visit，Grand Theatre 的话题为Beautiful butterflies. 本单元的Wonderland中出现的词汇是关于昆虫的，an ant/a bee/a ladybird/a dragonfly/a cockroach/a butterfly,其中“ant/bee/butterfly”

在以前的学习过程中已经有所接触，但是部分学生有所遗忘，本课中应着重教学“dragonfly, cockroach, butterfly”, 这几个新授单词,读音较难，

可以通过创设教材分析

情境，让学生在实际的情境中熟练运用，同时注意语音，这样，学生能扎实牢固掌握这几个词。

本单元Farmland中的句型是… like to …, 这一句型结构曾出现过，学生已有一定的基础。在教学中可将Wonderland和Farmland的句型… like to …整合在一起教学，让学生了解这些昆虫的生活习性，还可通过相关的图片进行教学。

本单元的Grand Theatre主题是Beautiful butterflies, 主要是… like to …句型的呈现。经过Farmland的学习和巩固，课文的句子对学生来说已经没有难度。重点在于even, clever, real, trick, enemy这几个单词，对课文中出现的生词要反复操练。同时要培养学生从小养成爱护有益昆虫的好习惯。

为了便于介绍昆虫的生活习性，使学生较全面地了解这些昆虫的特性，因此本节课拓展了两个词汇，即：feeler wing。想必学生易于接受，也乐意去学。

本单元的词汇和句型学生在以前的学习过程中已经有所接触，而且学生对昆虫较为兴趣，对本课的主题，学生也较为感兴趣，学生很愿意去讲述自己的喜好，学情分析

特别是自己对昆虫的了解，但是学生在叙述时会出现诸多的错误，例如单词“dragonfly, cockroach, butterfly”,部分学生会发生读音错误，应通过创设情境，让学生在实际的情境中熟练运用。
