Unit 5 A healthy lifestyle Grammar 教学设计 2025-2026学年译林版（2024）七年级英语上册

Unit 5 A healthy lifestyle-Grammar This grammar section in Unit 5 of the 2024 Yilin English textbook for Grade 7 focuses on countable and uncountable nouns. It is an essential part of the unit which revolves around the theme of a healthy lifestyle. By learning about countable and uncountable nouns, students can more accurately describe various elements related to a healthy lifestyle, such as different kinds of food (countable: apples, bananas; uncountable: milk, water), amounts of exercise, and so on. This knowledge will not only strengthen their grammar foundation but also enable them to express ideas more precisely in the context of the unit's theme. 教学目标 Students will be able to distinguish between countable and uncountable nouns. They can master the basic forms and plural forms of countable nouns, as well as the expressions for quantity of uncountable nouns. Students will understand how to use appropriate determiners (a/an, some, any, much, many, etc.) with countable and uncountable nouns. 教学重难点 A. Teaching Key Points The definition and characteristics of countable and uncountable nouns. The formation of plural forms of countable nouns, especially irregular plurals. The usage of determiners with countable and uncountable nouns, such as "a/an" for singular countable nouns, "some/any" for both countable and uncountable nouns in different sentence types, and "much/many" for uncountable and countable nouns respectively. B. Teaching Difficult Points Helping students correctly judge whether a noun is countable or uncountable, as some nouns can be both countable and uncountable in different contexts. Mastering the usage of quantity expressions for uncountable nouns, like "a piece of", "a cup of", etc., and using them appropriately in sentences. Training students to use countable and uncountable nouns accurately in real - life communication and writing, avoiding common mistakes. A. Countable Nouns Definition: Countable nouns are nouns that can be counted. They have a singular form and a plural form. Plural Forms Most countable nouns form their plurals by adding "-s" at the end. For example: book - books, pen - pens. Nouns ending in "-s", "-x", "-sh", "-ch" form their plurals by adding "-es". For example: bus - buses, box - boxes, dish - dishes, watch - watches. Nouns ending in a consonant + "y" change the "y" to "i" and add "-es". For example: city - cities, family - families. Nouns ending in a vowel + "y" just add "-s". For example: boy - boys, day - days. Some nouns have irregular plural forms. For example: man - men, woman - women, child - children, foot - feet, tooth - teeth. Determiners: We use "a/an" before singular countable nouns when we talk about one of something. For example: a book, an apple. In plural forms, we can use "some", "any", "many", "a few", etc. For example: some books, many apples, a few oranges. B. Uncountable Nouns Definition: Uncountable nouns are nouns that cannot be counted as separate individual units. They usually refer to substances, abstract concepts, or groups. Quantity Expressions: Since uncountable nouns cannot be counted directly, we use expressions like "a piece of", "a cup of", "a glass of", "a bottle of", "some", "any", "much", "a little", etc. to indicate quantity. For example: a piece of bread, a cup of tea, some water, much milk, a little sugar. Determiners: We use "some", "any", "much", "a little", etc. with uncountable nouns. "Some" is used in affirmative sentences, and "any" is used in negative sentences and questions. For example: There is some juice in the glass. Is there any water in the bottle? There isn't much time left. 教学过程 A. Warming - up (5 minutes) Greet the students as usual. Show some pictures related to a healthy lifestyle on the PPT, such as pictures of different kinds of food (apples, bananas, milk, bread), sports equipment (basketball, football), and ask students to describe what they see in English briefly. This activity can review the vocabulary learned before and lead in to the grammar topic naturally. For example, ask: "What can you see in this picture? How do you describe it in English?" B. Presentation (10 minutes) Write some sentences on the blackboard, such as "I have an apple. I have two apples. I like milk. I need some water." Underline the nouns "apple", "apples", "milk", and "water". Explain the concept of countable and uncountable nouns to the students. Point out that "apple" is a countable noun because we can count how many apples there are, and it has a singular form "apple" and a plural form "apples". While "milk" and "water" are uncountable nouns as we cannot count them one by one, and they don't have a plural form in the regular sense. Use more examples on the PPT to illustrate the difference, showing pictures of countable and uncountable things and giving corresponding sentences. For example, show a picture of eggs and say "These are eggs. Eggs are countable nouns." Then show a picture of rice and say "This is rice. Rice is an uncountable noun." C. Explanation and Practice (15 minutes) Countable Nouns Explain the rules of forming plural forms of countable nouns in detail with more examples on the PPT. After each rule explanation, give students some exercises on the blackboard or through PPT, such as asking them to change the singular nouns to plural forms. For example: "cat - ____", "brush - ____", "city - ____". Have a quick review of irregular plural forms of countable nouns by showing pictures and asking students to say the plural forms. For example, show a picture of a man and a group of men, and ask "What's the plural form of'man'?" Practice using determiners with countable nouns. Give some incomplete sentences on the PPT, like "I have ____ (a/an) book. Do you have ____ (some/any) pens? There are ____ (many/a few) apples on the table." and ask students to fill in the blanks. Uncountable Nouns Explain how to express the quantity of uncountable nouns using phrases like "a piece of", "a cup of", etc. Show pictures on the PPT, such as a picture of a piece of paper and say "This is a piece of paper. Paper is uncountable, so we use 'a piece of' to show a certain amount." Do some exercises about quantity expressions for uncountable nouns. Write some uncountable nouns on the blackboard, such as "bread", "news", "information", and ask students to come up with quantity expressions for them. Practice using determiners with uncountable nouns. Give sentences like "There is ____ (some/any) milk in the fridge. I don't have ____ (much/many) time. Would you like ____ (some/any) water?" on the PPT and let students fill in the blanks. D. Group Activity (10 minutes) Divide the students into groups of four or five. Give each group a task: to make a dialogue about a healthy lifestyle, using at least five countable nouns and five uncountable nouns correctly. For example, the dialogue can be about planning a healthy meal. They need to consider what food to buy, how much of each food to get, etc. Walk around the classroom, providing guidance and help to each group during their discussion and dialogue preparation. After a few minutes, ask some groups to come to the front of the class and act out their dialogues. The rest of the class listen carefully and check if they use countable and uncountable nouns correctly. E. Summary and Homework (5 minutes) Summarize the key points of countable and uncountable nouns, including their definitions, plural forms (for countable nouns), quantity expressions (for uncountable nouns), and the usage of determiners. Assign homework: Ask students to write a short passage about their own healthy lifestyle, using at least ten countable nouns and ten uncountable nouns. Let them make a poster about healthy food, labeling the food as countable or uncountable and writing some simple sentences under each picture. 教学反思 Positive Aspects The warming - up activity was effective in attracting students' attention and quickly getting them into the English - learning atmosphere. The pictures related to a healthy lifestyle not only reviewed vocabulary but also smoothly led to the grammar topic. The step - by - step explanation of countable and uncountable nouns, combined with plenty of examples and exercises, helped most students understand the basic concepts and usage rules. The group activity provided students with an opportunity to practice using the grammar knowledge in a real - life - like situation, which enhanced their communication ability and cooperation spirit. Areas for Improvement Some students still had difficulty in distinguishing between countable and uncountable nouns, especially those nouns that can be both in different contexts. More in - depth explanations and additional examples in future classes are needed. During the group activity, some groups spent too much time on thinking about the content of the dialogue rather than focusing on the correct usage of countable and uncountable nouns. In the future, more specific guidance on grammar usage during group activities should be given. The time for students to present their group dialogues was a bit rushed. In the next class, more time can be allocated to ensure that each group has enough time to show their work and for the whole class to have a more comprehensive discussion. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
