［What］本节课围绕主题语境设计了四个活动：第一部分是识别动词-ing 形式作主语的特征和功能。第二部分是将含有it作形式主语的句子改写成动词-ing 形式作主语的句子。第三部分是根据上下文选择正确的单词的-ing形式填空，并判断其功能。第四部分要求介绍学校出游的一个当地景点，尽可能多地使用动词-ing形式，并分析其功能。

［Why］在本单元主题语境中学习动词-ing 形式作主语的用法，让英语句式表达更丰富多彩。

［How］本课以例句示范、改写句子、补全语篇、介绍一个当地景点的形式，使学生识别动词-ing 形式作主语的特征，练习动词-ing 形式作主语的用法，使学生能用动词-ing 形式作主语描述景物或人，在语法学习的过程中加深对主题意义的理解。

学情分析

学生在之前已经学习-ing形式作定语、状语和宾语补足语的用法，在本课学习-ing作主语这一知识点本身难度不大，学习掌握起来相对容易，所以要

趁机抓住课堂时间进行语法练习的操练，让学生及时复习-ing作定、状和宾补并且巩固理解-ing作主语，全面系统掌握非谓语动词-ing。

③Spreading out before me, branches of the Rapa River flow through the valley below.

④ Around 9,000 years ago, this ice melted, leaving behind about 100 glaciers．

⑤Following the reindeer were the Sami people, who made this territory their home.

⑥Getting here is quite difficult, so apart from the Sami very few people have ever seen Sarek.

⑦For hundreds of years, looking after reindeer was a way of life for the Sami.

⑧ But every spring, a small number of Sami still follow their reindeer into the valleys of Sarek, living in tents or old cottages and enjoying their traditions.

⑨ For example, this morning my breakfast is flat bread warmed over a fire, dried reindeer meat, and some sweet and sour berries that I found growing near my tent.

⑩ Here I am, alone under this broad sky, breathing the fresh air， and enjoying this great adventure is territory their home.

在具体语境中分析句子结构，识别动词-ing形式所作的成分。区别动词-ing形式作主语和作状语、补语等的不同用法，初步认识和理解动词-ing形式作主语的特征。

Step3

Rewrite each of the following sentences using the-ing form as the subject. How does the sentence focus change?

EXAMPLE

It is challenging yet really fascinating to hike through the mountains in the pathless Sarek.

→Hiking through the mountains in the pathless Sarek is challenging yet really fascinating.

①It is both challenging and rewarding to study abroad.
