Show some pictures of beautiful natural scenery, such as clean beaches, clear rivers, and green forests, and ask students: "How do you feel when you see these pictures?" Then show some pictures of polluted environments, like beaches full of garbage, dirty rivers, and smog - filled skies, and ask: "What about these pictures? How do you feel now?" Lead students to talk about their feelings and introduce the topic of environmental protection. 2. Pre - listening (8 minutes) Write two questions on the blackboard: How often do you clean your house? How does plastic pollution affect sea life? Let students think about these questions and discuss them in pairs. Then ask some pairs to share their answers with the class. Present new words and phrases related to the topic. Use pictures or real - life examples to help students understand. For example, show a plastic bottle and teach the word "plastic" and "bottle", and then throw the bottle into a bin and teach "bin". Explain the meaning and usage of "recycle", "be harmful to", etc. by giving examples. Drill the new words and phrases. Read them aloud several times, and then ask students to read after you, first in chorus and then individually. Correct their pronunciation in time. 3. While - listening (12 minutes) Tell students that they are going to listen to a conversation among Jenny, Danny, and Brian during their beach vacation. Let them listen carefully and answer the following questions: Who is having a vacation on the beach? Who finds the plastic in the ocean? What is Brian's idea about the garbage on the beach? How do they feel after cleaning up the beach? Play the recording for the first time. Students listen and try to answer the questions. After that, check the answers with the class. Play the recording again. This time, ask students to fill in the blanks in the handout: Jenny, Danny, and Brian were on a beach vacation with their families. Jenny stepped on a ______________. Danny saw a man leaving his garbage on the beach. They thought the situation would ____________ if people did not take action to protect the beach. So they decided to ____________ the beach. They asked their family members to help. They spent the afternoon ___________ all kinds of garbage on the beach. They __________ that they made a difference in keeping the beach clean and protecting the ocean and its creatures. Check the answers and let students read the completed passage aloud to ensure they understand the content of the dialogue. 4. Post - listening (12 minutes) Divide students into groups of four. Let them role - play the dialogue in their groups. Encourage them to use their own voices and expressions to make the role - play more vivid. After the role - play, ask some groups to come to the front of the class and perform the dialogue for the whole class. Other students watch and listen carefully, and then give their comments and evaluations. Have a group discussion. Pose the question: "What else can we do to protect the environment besides cleaning up the beach?" Each group discusses and writes down as many ideas as possible. Then each group selects a representative to report their ideas to the class. Write the good ideas on the blackboard. 5. Summary and Homework (8 minutes) Summary: Summarize the key points of this lesson with the students, including new words, phrases, sentence patterns, and the main idea of the dialogue. Emphasize the importance of environmental protection. Homework: Ask students to write a short passage about an environmental problem they are concerned about and the solutions they think of. They should use at least five words and three sentence patterns learned in this lesson. Encourage students to start from small things in their daily lives to protect the environment, such as reducing the use of plastic bags, recycling waste paper, etc., and record their actions in a small notebook. 教学反思 After this lesson, students should have a better understanding of environmental protection, especially plastic pollution, and master some related English words, phrases, and sentence patterns. The use of pictures, recordings, role - plays, and group discussions can effectively arouse students' interest and enthusiasm, and help them actively participate in classroom activities. However, there may still be some problems. For example, in the group discussion part, some students may not be able to express their ideas fluently due to limited language ability. In the future teaching, more language input and speaking practice should be provided. Also, when dealing with the difficult point of the conditional sentence, more examples and exercises can be given to help students better understand and use it. In general, this lesson should achieve the expected teaching goals, but continuous improvement is needed to better meet the learning needs of students. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
