Lead - in (5 minutes) Greet the students and show them some pictures of common plants and animals, such as a dog, a cat, a flower, and a tree. Ask them simple questions like “What can you see in the picture?” and “What do you think of this animal/plant?”. This can quickly arouse students' interest and lead them into the topic of plants and animals. Then, show some pictures of amazing plants and animals, such as a blue whale, a redwood tree, and a cheetah. Ask students, “What makes these plants and animals amazing?”. Let students express their opinions freely, which can activate their prior knowledge and prepare them for the following learning content. 2. Presentation (10 minutes) Vocabulary teaching Write the new words “moss”, “redwood”, “cheetah”, “bamboo” on the blackboard. Pronounce each word clearly and ask students to repeat after you several times. Then, explain the meaning of each word with the help of pictures. For example, show a picture of moss growing on a rock and explain that moss is a very small and old - fashioned plant. Teach the descriptive adjectives in the same way. Write “old”, “tall”, “fast”, “heavy”, “large”, “long”, “small”, “beautiful”, “big”, “short” on the blackboard. Use real - life examples or pictures to help students understand their meanings. For example, point to a tall building and say “tall”, or show a picture of a big elephant and say “big”. Drill the pronunciation of these words with students, paying attention to the correct intonation and stress. Grammar teaching - Superlative form of adjectives Write some simple sentences on the blackboard, such as “The elephant is big. The blue whale is bigger than the elephant. The blue whale is the biggest animal in the world.”. Guide students to observe the changes of adjectives in these sentences and introduce the concept of the superlative form of adjectives. Explain the rules of forming the superlative form of regular adjectives as mentioned in the knowledge list, giving more examples for each rule. For irregular adjectives, list them on the blackboard and ask students to remember them. Do some simple oral exercises with students. Give an adjective, and ask students to say its superlative form. For example, say “fast”, and students answer “fastest”. 3. Practice (15 minutes) 1a Show the pictures in 1a on the screen. Ask students to look at the plants and animals in the pictures and use the words in the box to talk about them. Let students work in pairs. One student points to a picture and says, for example, “What can you say about the moss?”, and the other student answers, “It's old and small.”. Walk around the classroom to monitor their conversations and offer help if necessary. After a few minutes, invite some pairs to share their conversations with the whole class. 1b Tell students that they will listen to some conversations about the plants and animals in 1a. First, let them look at the pictures and the names of plants and animals in 1b to get familiar with the content. Play the recording for the first time. Ask students to just listen and get a general idea of the conversations. Play the recording again. This time, ask students to number the plants and animals in 1a in the order they hear them. Check the answers with the class. 1c Explain the task in 1c to students. They will listen to the recording again and match the words with the plants and animals in 1a. Some may have two answers. Play the recording for the third time. Students listen carefully and complete the matching. Check the answers with the class. Ask students to explain why they match in that way, which can help them better understand the characteristics of plants and animals described in the conversations. 4. Production (10 minutes) 1d Let students work in pairs again. Ask them to ask and answer questions about the plants and animals in 1a using the superlative form of adjectives. For example, “What's amazing about the blue whale? - It's the largest/biggest animal in the world.”. Encourage students to add more information, such as “It's also the heaviest animal in the world.”. Walk around the classroom to listen to their conversations and give guidance. Notice if students are using the superlative form of adjectives correctly. After a while, invite several pairs to come to the front of the classroom and act out their conversations for the whole class. Give praise and positive feedback to students. Group discussion Divide students into groups of four or five. Give each group a topic: “If you could choose one amazing plant or animal to live with you, which one would you choose and why?”. Let students discuss in their groups. They should use the vocabulary and sentence patterns they have learned in this class to express their opinions. For example, “I would choose a cheetah because it's the fastest land animal. It would be so exciting to see it run.”. Each group selects a representative to report their discussion results to the whole class. 5. Summary and Homework (5 minutes) Summary Summarize the key points of this class with students. Review the new vocabulary about plants, animals, and their characteristics, as well as the superlative form of adjectives. Ask students to recall some important sentence patterns. Emphasize the importance of protecting plants and animals and respecting the biodiversity of nature. Homework Ask students to write a short passage about their favorite amazing plant or animal, using at least five sentences with the superlative form of adjectives. Let students search for more information about an amazing plant or animal they are interested in on the Internet and share it with the class in the next class. 教学反思 Positive aspects The use of pictures and real - life examples in the lead - in and presentation stages effectively attracted students' attention and made the new knowledge easier to understand. Most students were actively involved in classroom activities, especially in pair - work and group - discussion activities, which improved their speaking and cooperation abilities. The step - by - step practice process, from vocabulary recognition to sentence - making and listening exercises, helped students gradually master the key knowledge. The oral and written exercises in class also provided students with opportunities to practice and consolidate what they had learned. Areas for improvement Some students still had difficulties in using the superlative form of irregular adjectives correctly. In future classes, more exercises and special attention should be given to irregular forms. During the group - discussion activity, a few students were a bit shy and did not actively participate. In the future, more encouragement and guidance should be provided to these students to make them more involved in group activities. The time for each activity should be more precisely controlled. In some cases, the practice activities took a little longer, which made the production stage a bit rushed. In future teaching, the time allocation should be adjusted more carefully to ensure that each teaching link can be carried out smoothly. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
