Unit 4 Then and now-D Changes in our lives (Writing & Discovery) This unit focuses on the theme of "Then and now", aiming to guide students to explore and discuss the changes in people's lives, society, and the environment. In this part of "D Changes in our lives (Writing & Discovery)", students will mainly learn to describe changes in different aspects, such as transportation, communication, and lifestyle. Through various activities, students will enhance their writing skills, especially in organizing ideas, using appropriate words and sentence structures to express changes. They will also discover some underlying reasons for these changes and think about the impact of these changes on people's lives. The content is closely related to students' daily lives, which can arouse their interest and make it easier for them to understand and participate in the learning process. 教学目标 Students will be able to master key vocabulary and phrases related to changes, such as "used to", "in the past", "nowadays", "change from...to...", "with the development of", etc. Students will learn different sentence structures for describing changes, like "People used to do sth., but now they do sth. else." and "There have been great changes in...". Students can understand and use some common adjectives to describe the features of different times, such as "convenient", "efficient", "traditional", "modern". 教学重难点 A.

Lead - in (5 minutes) Show some pictures of old - fashioned transportation (such as horse - drawn carriages) and modern transportation (such as high - speed trains) on the PPT. Ask students: "Look at these pictures. What can you see? Can you tell the differences between them?" Let students freely express their opinions. Then show some pictures of communication tools in the past (like telegraphs) and now (like smartphones). Pose the question: "How did people communicate in the past? How about now? What changes have taken place?" Guide students to think about the changes in different aspects of life. B. Knowledge Presentation (10 minutes) Write the key vocabulary and phrases on the blackboard, and explain their meanings and usages one by one. For example, when teaching "used to", give examples like "I used to go to school by bike, but now I take the subway." and explain that "used to" is used to describe past habits or states that no longer exist. Present different sentence structures for describing changes on the PPT. Analyze the grammar and let students read the examples aloud to get familiar with them. For instance, for "There have been great changes in...", show examples such as "There have been great changes in our city's appearance in recent years." Divide students into pairs. Let them make up sentences using the learned vocabulary, phrases and sentence structures, and then ask some pairs to share their sentences with the class. C. Reading and Analysis (10 minutes) Provide a short passage about the changes in people's diet on the handouts. The passage can include information like "In the past, people mainly ate simple and staple foods. However, nowadays, with the improvement of living standards, people have a more diverse diet, including various kinds of fruits, vegetables, and high - quality proteins." Let students read the passage silently for the first time, and ask them to find out the main idea of the passage. Then, ask them to read it again carefully and analyze how the author describes the changes in diet, such as what vocabulary, phrases and sentence structures are used. Organize a class discussion. Ask students: "What are the reasons for the changes in people's diet?" Guide students to think about factors like economic development, improvement of agricultural technology, and changes in people's health awareness. D. Writing Guidance (10 minutes) Set a writing topic, for example, "Changes in My Neighborhood". Brainstorm with students about the aspects that can be written, such as the appearance of buildings, the transportation situation, the facilities in the neighborhood, etc. Write these aspects on the blackboard. Guide students to organize their writing ideas. Suggest they can start with a general statement about the changes in the neighborhood, then describe the situation in the past and the present in different aspects respectively, and finally analyze the reasons for these changes briefly. Let students start writing. Walk around the classroom to provide individual guidance, helping students with grammar mistakes, vocabulary usage, and organization of ideas. E. Sharing and Evaluation (5 minutes) Ask several students to come to the front of the classroom and read their written passages aloud. After each student finishes reading, let other students give their comments, such as what they think is well - written and what can be improved. The teacher also gives comprehensive evaluations, praising the students' good points, such as clear organization, accurate use of vocabulary and grammar, and at the same time, pointing out the common problems and providing suggestions for improvement. F. Summary and Homework Assignment (5 minutes) Summarize the key points of this class, including the vocabulary, phrases, sentence structures for describing changes, and the writing skills learned. Assign homework: Ask students to choose another aspect of life, such as entertainment or education, and write a more detailed passage about the changes. They are required to use at least 80 words and include the description of the past, the present, and the reasons for the changes. 教学反思 After this class, students have shown a certain level of interest in the topic of "Changes in our lives". Through various activities, most students have mastered the key vocabulary, phrases and sentence structures for describing changes, and can write simple passages about changes in a certain aspect. However, there are still some problems. Some students have difficulty in using vivid and diverse language to describe changes, and their writing is rather monotonous. In future teaching, more sample writings with rich language expressions can be provided for students to imitate and learn. Also, in the process of group discussion and individual writing, some students are less active. It is necessary to further encourage these students to participate actively and create a more relaxed and supportive learning atmosphere. Overall, this class has achieved most of the teaching objectives, but there is still room for improvement in teaching methods and student guidance. 2 / 37 学科网(北京)股份有限公司 学科网(北京)股份有限公司 $$
