Insects I Know 课型

第一课时

本课选自新世纪四年级教材Unit12，单元主题为Beautiful butterflies。本单元的核心板块为Farmland, Wonderland和Grand Theatre。Wonderland板块学习昆虫类词汇“ant, bee, dragonfly, ladybird, cockroach, butterfly”；

Farmland板块学习句型“…like to…”；Grand Theatre板块则对蝴蝶这一昆虫进行了具体的描述。

本单元的昆虫类词汇在新世纪教材2BU11和3AU5已学习过；“…like to…”的句型也曾出现过，之后在五年级也会出现“What does…like to do?”的问句学习。因此，基于教材板块、单元主题、语言材料和图片情境，重组三个板块，设计了三个课时：

Period1 Insects I Know讲述Sandy, Alice和Tom一起去参观昆虫世界的情景。

Period2 Knowing more about Insects 通过课后查阅资料以及课上交流互动，更加细致地描述昆虫的各个部位，昆虫这些部位的不同作用。

Period 3 My Favourite Insect以蝴蝶为例，学习如何表述自己最喜欢的昆虫。

本课是单元中的第一课时，创设的情景是Sandy, Alice和Tom一起去参观昆虫世界，主要围绕三个问题展开：What can they see in the Insect world? What do they think of these insects? What do the Insects like to do? 内容上通过层层推进的方法，先复习巩固已学昆虫类词汇，再描述昆虫外观，再描述昆虫喜欢做的事。在创设的语境中渗透了Farmland中的“…like to…”句型，主要是描述昆虫喜欢做的活动。预设的目标是让学生能够模仿三位小朋友的语段，简单描述所学昆虫的外观和习性。同时也能通过语境激发起学生探究昆虫知识的热情，这也为第二课时奠定了情感基础。

学情分析

教学对象是小学四年级第一学期学生，他们已经具备了基本的听说读写的能力，能在情境中运用所学单词、词组进行简单表达。对英语学习也有了较浓厚的兴趣。大部分学生有良好的倾听、表达、阅读、书写的英语学习习惯。但同时，他们年龄小，易兴奋、易疲劳，注意力也容易分散，不能35分钟全

程关注英语课堂。因此，本课创设了昆虫世界参观昆虫的情景，通过图片、儿歌、歌曲、小组朗读、男女对话、师生对话及表演等不同形式，激发学生学习英语的兴趣，并让学生在模仿中争取再创造。

另外，本课的昆虫类单词在以前的学习过程中有所接触，但相隔时间太久，部分学生有所遗忘。这节课在巩固所学知识的基础上，简单描述昆虫的外貌特征。“…like to…”句型在本教材中前面的单元中出现过，所以学生也能初步感知并听懂句型“I like to…”。
