Unit 5 Water is life-Section 2 Exploring and applying rules (Grammar) This grammar section of Unit 5 “Water is life” focuses on helping students master quantity words and relevant interrogative sentences. Through real - life scenarios such as Du Yun’s family checking water and drink quantities during a holiday storm, students are guided to understand and use words and phrases like “a few”, “many”, “a little”, “much”, “a lot of”, “too many”, “too much”, “too few”, “not enough” and “no” to describe countable and uncountable nouns. They will also learn to ask questions about quantity using “How many” and “How much”. This knowledge is closely related to the theme of water, allowing students to express the quantity of water and other substances in daily life, which is not only practical for language learning but also helps to deepen their understanding of the importance of water resources. 教学目标 Students will be able to distinguish between countable and uncountable nouns accurately. Master the usage of quantity words such as “a few”, “many”, “a little”, “much”, “a lot of”, “too many”, “too much”, “too few”, “not enough” and “no” to modify countable and uncountable nouns. Learn to use “How many” and “How much” to ask questions about quantity. 教学重难点 1 Key Points The correct usage of quantity words with countable and uncountable nouns. The proper use of “How many” and “How much” in interrogative sentences. 2 Difficult Points Helping students distinguish between “a few” and “few”, “a little” and “little”, as well as “too many”/“too much” and “not enough”. Applying the learned grammar knowledge flexibly in different contexts, especially in speaking and writing. 1 Countable and Uncountable Nouns Countable Nouns: Nouns that can be counted, representing specific and separable things. They usually have singular and plural forms. For example, “apple - apples”, “book - books”. The plural form is usually formed by adding “-s” or “-es” to the singular form. For nouns ending with “-y” preceded by a consonant, change “y” to “i” and add “-es” (e.g., “baby - babies”); for nouns ending with “-s”, “-x”, “-ch”, “-sh”, add “-es” (e.g., “bus - buses”, “box - boxes”, “watch - watches”, “dish - dishes”); for nouns ending with “-o”, if it is a living thing, add “-es” (e.g., “tomato - tomatoes”), if it is non - living, add “-s” (e.g., “piano - pianos”). Uncountable Nouns: Nouns that cannot be directly counted, often representing liquids, substances, abstract concepts, etc. They have only a singular form. For example, “water”, “milk”, “love”, “success”. Uncountable nouns can be quantified by using phrases like “a piece of”, “a bottle of”, “a bar of” etc. For example, “a piece of paper”, “a bottle of water”, “a bar of chocolate”. 2 Quantity Words For Countable Nouns: “How many”: Used to ask about the number of countable nouns. For example, “How many apples are there in the basket?” “A few”: Means a small number, used to express a positive quantity. For example, “There are a few books on the desk.” “Many”: Indicates a large number. For example, “Many students like playing basketball.” “Too many”: Implies an excessive number. For example, “There are too many people in the room.” “Too few”: Means not enough in number. For example, “We have too few chairs for all the guests.” “(Not) enough”: “Enough” means a sufficient amount. “Not enough” means lacking. For example, “We have enough pens. We don't have enough paper.” “No”: Means none. For example, “There are no apples left in the fridge.” For Uncountable Nouns: “How much”: Used to ask about the amount of uncountable nouns. For example, “How much water is there in the bottle?” “A little”: Means a small amount, used to express a positive quantity. For example, “There is a little milk in the glass.” “Much”: Indicates a large amount (usually used in negative and interrogative sentences in this context). For example, “Do you have much homework today? I don't have much time.” “Too much”: Implies an excessive amount. For example, “There is too much sugar in the coffee.” “Not enough”: Means lacking. For example, “We don't have enough water.” “No”: Means none. For example, “There is no water in the cup.” “A lot of”/“Lots of”: Can be used with both countable and uncountable nouns to mean a large amount or number. For example, “There are a lot of books in the library. There is a lot of water in the lake.” 教学过程 1 Lead - in (5 minutes) Activity: Show some pictures of different scenes, such as a fridge filled with various food and drinks, a supermarket shelf with goods, and a classroom with desks and chairs. Ask students to describe what they see in terms of quantity in Chinese first. For example, in the fridge picture, there are some bottles of milk, a few cartons of yogurt, and a lot of fruits. Purpose: This activity aims to activate students' prior knowledge about quantity in their mother tongue and arouse their interest in learning how to express quantity in English, laying a foundation for the following grammar learning. 2 Presentation (10 minutes) Countable and Uncountable Nouns Review: Write some nouns on the blackboard, such as “apple”, “water”, “book”, “milk”, “student”, “success”. Ask students to classify them into countable and uncountable nouns. Then review the definitions and characteristics of countable and uncountable nouns with examples. Show some more complex examples of forming plurals of countable nouns and how to use quantifiers with them. Quantity Words Introduction: Present the quantity words one by one. Use simple sentences on the PPT to illustrate their usage. For example, for “a few”, show “I have a few friends.”; for “many”, show “Many birds are flying in the sky.”; for “a little”, show “There is a little honey in the jar.”; for “much”, show “How much money do you have?” Compare the usage of quantity words for countable and uncountable nouns side by side, for example: Explain the meaning and usage differences of “a few” and “few”, “a little” and “little”, “too many”/“too much” and “not enough”. 3 Practice (15 minutes) Listening Practice: Play a short dialogue recording. In the dialogue, people are talking about the things they have at home, such as the quantity of food, drinks and daily necessities. Students need to listen carefully and fill in the blanks with the correct quantity words they hear. For example: A: How ______ apples do we have? B: We have ______ apples. Maybe five or six. A: How ______ milk is there in the fridge? B: There is only ______ milk. We need to buy some more. Check the answers together and play the recording again if necessary for students to understand better. Oral Practice: Divide students into pairs. Each pair is given a set of flashcards with pictures of different things (both countable and uncountable). One student shows a card and asks the other about the quantity using “How many” or “How much”. The other student answers with the appropriate quantity word. For example, if one shows a card with three books, the question is “How many books are there?”, and the answer could be “There are three books.” or “There are a few books.” If the card shows a glass of water, the question is “How much water is there?”, and the answer could be “There is a little water.” Walk around the classroom to monitor and provide guidance when students make mistakes. 4 Production (10 minutes) Group Work: Divide students into groups of four. Each group is asked to create a short skit about a family preparing for a picnic. They need to talk about the quantity of food, drinks and other items they are going to take. For example, “We have a lot of sandwiches, but only a little juice. We need to buy some more drinks. How many apples should we take? Maybe a few more.” Each group has 5 minutes to prepare the skit. Then invite some groups to perform in front of the class. After each performance, other students can ask questions about the quantity expressions used in the skit. Writing Practice: Ask students to write a short passage about the things in their own fridge. They should describe the quantity of different food and drinks using the learned quantity words. For example, “In my fridge, there are many eggs and a few tomatoes. There is a lot of milk and a little yogurt. But there is no juice. I think I need to buy some juice.” After students finish writing, ask them to exchange their passages with their partners and check for grammar and quantity word usage mistakes. 5 Summary and Homework (5 minutes) Summary: Review the key points of this class with students, including the difference between countable and uncountable nouns, the usage of quantity words, and how to ask questions about quantity. Ask students to share what they have learned in this class. Homework: Ask students to make a shopping list for their family. They need to write down the things their family needs and the quantity of each item. For example, “2 kilos of rice, 3 bottles of juice, a few apples, etc.” Ask students to observe the things around them in their daily life and write down at least 5 sentences using quantity words to describe the quantity of different things. 教学反思 After this class, students should have a better understanding of countable and uncountable nouns and be able to use quantity words and relevant interrogative sentences to describe the quantity of things. However, there may still be some problems. For example, some students may still have difficulty distinguishing between “a few” and “few”, “a little” and “little”. In future classes, more practice and detailed explanations can be provided. The group work and skit - performing activities seem to be well - received by students, which can effectively improve their language application ability and teamwork spirit. But in the future, more time can be allocated for students to prepare to ensure a better performance. Also, in the writing practice, some students may make mistakes in grammar and spelling. Teachers need to pay more attention to individual guidance and strengthen writing training in subsequent classes. Overall, this grammar class should be adjusted and improved according to students' actual learning situations to better meet their learning needs. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
