教学重难点
1. Key Points
The acquisition of plant - related vocabulary and expressions.
Understanding the basic ecological functions of plants.
2. Difficult Points
Helping students understand the complex ecological relationships that plants are involved in, such as the oxygen - carbon dioxide cycle.
How to guide students to think deeply about the importance of plants in different aspects of life.
1. Vocabulary
Parts of plants: leaf (pl. leaves), flower, stem, root
Substances related to plants: oxygen, carbon dioxide
Verbs about plant growth and functions: grow, produce, give off, take in
Expressions: be useful for, the growth of the plant, mean a lot to
2. Facts about plants

教学过程
1. Warming - up (5 minutes)
Greet the students as usual. Then show some pictures of various animals on the PPT, such as dogs, cats, birds, and ask students to name them in English. After that, ask: "We all know these animals. But today, we are going to explore another group of our friends. Guess what they are?" Then show a picture of a big tree, and lead in the topic of plants.
Purpose: Arouse students' interest and quickly bring their attention to the class. Review animal - related vocabulary and smoothly transition to the new topic of plants.
2. Pre - reading (10 minutes)
Present several pictures of different plants on the PPT, including a sunflower, a cactus, a fern, etc. Point to each picture and ask students simple questions, like "What's this in English?", "Do you know where this plant usually grows?"
Then show a picture of a plant and some words on the blackboard, such as "leaf", "flower", "stem", "root". Let students come to the blackboard and write the words next to the corresponding parts of the plant picture.
Purpose: Activate students' prior knowledge about plants and help them review and learn some basic plant - related vocabulary in a simple and intuitive way.
3. While - reading (15 minutes)
Hand out a short passage about plants to each student. The passage can include basic information such as "Plants are important for our life. They give off oxygen. We need oxygen to breathe. Plants have different parts, like roots, stems, leaves and flowers. Roots help plants get water and nutrients from the soil."
Ask students to read the passage silently for the first time, and then answer some general questions, like "What do plants give off?", "What are the parts of plants mentioned in the passage?"
For the second reading, ask students to read it carefully and underline the new words and expressions. Explain the key words and expressions to them, such as "give off", "take in", "be useful for". Let students try to make sentences with these expressions.
Purpose: Improve students' reading comprehension ability, help them learn new knowledge about plants, and master new words and expressions.
4. Post - reading (10 minutes)
Divide students into groups of four. Give each group a set of pictures that show the process of a plant growing from a seed to a mature plant, but the pictures are in the wrong order. Ask students to discuss in groups and put the pictures in the correct order. Then each group selects a representative to come to the front and explain the order of the pictures and the growth process of the plant in English.
After that, lead a class discussion: "Why are plants important to us?" Encourage students to express their opinions freely. Write their ideas on the blackboard, such as "Plants give us food", "They make the air clean", "They provide homes for animals".
Purpose: Strengthen students' understanding of plant growth through group activities, improve their cooperation ability and oral expression ability. And through the discussion, deepen students' understanding of the importance of plants.
5. Summary and Homework (5 minutes)
Summarize the key points of this class, including the vocabulary related to plants, the functions of plants, etc. Ask students to repeat the key words and expressions together.
Assign homework: Ask students to draw a picture of their favorite plant and write a short passage about it, introducing its name, appearance and why they like it. They need to use at least five words and expressions learned in this class.
Purpose: Help students review and consolidate what they have learned in class. The homework can not only train students' writing ability but also let them have a deeper understanding of plants.
教学反思
Overall, the teaching process of this class can effectively arouse students' interest in plants. Through various activities such as picture - matching, reading and group discussion, students are actively involved in the learning process, and most of them can master the key vocabulary and basic knowledge about plants. However, there are also some areas for improvement.
In the group activity of arranging plant growth pictures, some groups spent too much time discussing, resulting in a relatively short time for the subsequent class discussion. In future teaching, it is necessary to better control the time of each link. When explaining the difficult points, such as the oxygen - carbon dioxide cycle, some students still showed confusion. Maybe more vivid teaching aids or real - life examples should be used to help them understand. In the homework evaluation, more attention should be paid to students' individual differences, and appropriate guidance should be given to students with learning difficulties to ensure that they can also complete the homework tasks and improve their English level.
