教学语篇分析
I.Analysis of the integrated framework of the unit The core idea“conservation”is consistent with the theme(主题语境)“human V.S.nature”, falling into the thematic group(主题群)“nature and ecology”and“environmental protection” Animal bridges,also known as animal crossings,or wildlife bridges,are specially designed structures built to help wild animals to cross roads safely.The design and construction of animal bridges take into consideration the behaviors and habits of different animals.They are often placed in areas where wildlife frequently cross,such as migration routes or forest corridors. These bridges are typically constructed above the road and blend in with the surrounding natural environment.The construction of animal bridges is significant for the protection of wildlife and maintaining ecological balance.They provide a relatively safe crossing pathway for wildlife, helping them avoid collisions with vehicles.Additionally,animal bridges contribute to the preservation of biodiversity,maintaining connectivity between different areas for plants and animals,and promoting a healthy ecosystem. This lesson plays an important role in the unit,showing that harmonious coexistence with wild animals is achievable.Given the current urgent situation,more innovative initiatives should be taken to balance social development and environmental conservation,contributing to sustainable development.With“conservation”serving as the thread of the whole Unit,below is the integrated framework of the unit.

II.Analysis of the lesson [What]It introduces the problems caused by various human infrastructures and explains how to help animals to overcome physical and psychological barriers by constructing animal bridges in different forms.Additionally,clues for analyzing the features and benefits of building animal bridges are provided. [Why]To balance social development and environmental conservation,we need to think critically and make the right choices.By watching the video,viewers are convinced that wildlife bridges blending in with the surrounding natural environment is more appropriate than other solutions.Also,through the video,viewers may find bridges are specially adjusted to accommodate different animal sizes and habits,allowing them to cross freely.They will be motivated to think of more innovative ways to preserve nature and maintain ecological balance,contributing for sustainable development. [How] Adopting a linear structure,the 2'21"video starts with the physical and psychological obstacles faced by wild animals owing to human infrastructure,gradually unfolds the topic.After overturning the solution of removing human infrastructure,it introduces different forms of wild animal bridges tailored to various wild animals.Specific examples are given throughout the video,leading to better understanding of the main idea
Visual elements: To closely match the textual content,the video made by digital animation software includes many hand-drawn illustrations and real-life pictures.Some special visual effects are added to aid understanding.The overall color scheme is bright and appealing for the viewers. Audio elements:The narration in the video is explicit and concise,with authentic and clear pronunciation.Lively music is used to alleviate the pressure of absorbing a large amount of information. Humor: The video begins and ends with the image of a chick crossing the road,adding a humorous touch Language support: Owing to fast pace of the speech and many new words,the support of subtitles and visuals are needed to aid understanding,especially for senior high school students learning English.
学情分析
1.Most of the students are not familiar with animal bridges,so before the video is played,it's important to preview,activate students' background knowledge,arousing their interest. 2.Abundant information is covered with a lot of new words and phrases appearing in the video. To relieve students' cognitive burden,teachers could divide the video into several parts based on its content.Meanwhile,the new words could be taught before and during the class. 3.Owing to the fast pace of the narrator,students need subtitles and visuals to facilitate their understanding. 4.Pair work and group work are preferred by students to share their opinions.
教学目标
By the end of the class,students will be able to: 1.Sort out the reasons for constructing animal bridges by identifying the physical and mental barriers caused by various human infrastructures and focusing on the consequences. 2.Analyze the forms,features and benefits of wildlife bridges with the help of a supplementary video,forming structural knowledge of animal bridges 3.Practice viewing strategies such as active listening 、visual observation and note-taking. 4.Advocate animal bridges by making a presentation with what they have learned in the class by integrating “viewing”,“listening”and“speaking”skills.
5.Be motivated to think of more“crazy”innovative ideas to balance social development and environmental protection.
