Unit 6 Inventors and their inventions C Grammaring教学设计-2025-2026学年沪外教版七年级英语上册

Unit 6 C Grammaring教学设计 I. Teaching Objectives Master the usage of modal verbs “can”, “should”, and “must” to express possibility, advice, and necessity. Learn to use “What/How …!” exclamatory sentences to show strong feelings like excitement or surprise. Improve the ability to use these grammar points accurately in writing and speaking, enhancing grammatical correctness and expressiveness. II. Language Knowledge 1. Key structures Modal verbs: “can”: Expresses possibility, permission, or ability (e.g., “You can turn on the air conditioner.” “She can play the piano beautifully.”). “should”: Indicates advice or what is the right thing to do (e.g., “Scientists think we should make more use of green energy.”). “must”: Shows necessity or importance (sometimes a rule/law, e.g., “We must be very quiet in the library.”). Negative forms: “cannot (can’t)”, “should not (shouldn’t)”, “must not (mustn’t)”. Exclamatory sentences: “What + a/an + (adjective) + singular countable noun + (subject + verb)!” (e.g., “What a clever idea!”). “What + (adjective) + uncountable/plural noun + (subject + verb)!” (e.g., “What beautiful weather!”). “How + adjective/adverb + (subject + verb)!” (e.g., “How fast the rocket travels!”). 2. Key sentences When our ears are cold, we can wear earmuffs. “I must solve this problem,” he thought. Everyone in town thought they should have a pair of earmuffs. What a clever idea! What beautiful weather! What a great discovery the scientist made! How fast the rocket travels! How exciting the game is! A patent protects your creations, so others can’t copy, use, or sell them. You can get a patent for an invention if it is new, useful, and inventive. The invention can also be: a product, a process or an improvement on these. But you can’t get a patent for things such as scientific discoveries and rules. In China, you should apply as soon as possible after completing your invention. If you want protection in other places, you must apply separately. Alice is a good friend. → What a good friend Alice is! She works very hard for the final game! → How hard she works for the final game! It is an interesting book. → What an interesting book it is! She sings well. → How well she sings! He is a clever inventor. → What a clever inventor he is! Not every great invention was created according to a plan. Some, in fact, were the result of an accident. The scientist Dr Spencer Silver was doing research on strong glues. But he got one that “stuck lightly to surfaces.” At first, Silver had no idea what he could do with his discovery. Years later, another scientist, Art Fry, came to him with an idea. They created a bookmark that could stick to paper without damaging it. Finally, that bookmark became the sticky note. Now people can use sticky notes to remember things they should do. What an interesting accident! How lucky we are to have such a small invention! 3. Key and challenging points Understand and use “can” (possibility/permission/ability), “should” (advice), and “must” (necessity) correctly in different contexts. Form and use “What/How …!” exclamatory sentences accurately to express strong feelings. Apply these grammar points to complete sentences and passages about patents and inventions. III. Teaching Procedures Learning activities: Step 1 Study modal verbs (Activity C1) Analyze examples T: Study the blue parts and answer: What do the blue words mean in each sentence? Look at sentences with “can”, “must”, “should”. Explain “can” (wear earmuffs is allowed/possible), “must” (solving the problem is necessary), “should” (having earmuffs is a good idea). Then review grammar highlights (rules for “can”, “should”, “must” and their negatives). Step 2 Use modal verbs (Activity C2) Complete patent information card T: Complete the information card about patents with “can”, “can’t”, “should”, “must”. Ask Ss to fill in blanks about patent protection, what inventions can get patents, and application rules in China (e.g., “others can’t copy”, “You can get a patent”, “you should apply as soon as possible”, “you must apply separately”). Then check answers, explaining each modal verb’s use. Step 3 Study exclamatory sentences (Activity C3) Analyze examples T: Study the sentences and answer: What feelings can we express by “What…!/How…!” sentences? How do we form them? Show examples: “What a clever idea!”, “How fast the rocket travels!”. Explain they express excitement/surprise. Then review grammar highlights (structures for “What” and “How” exclamations). Step 4 Complete exclamatory sentences (Activity C4) Practice forming exclamations T: Complete the sentences using “What” or “How”. Ask Ss to transform sentences into exclamations (e.g., “Alice is a good friend.” → “What a good friend Alice is!”). Then check answers, ensuring correct structure. Step 5 Use grammar in passage (Activity C5) Complete invention passage T: Complete the passage about a small invention with “can”, “should”, “must”, “what”, “how”. Ask Ss to fill in blanks in the sticky note invention story, using modal verbs and exclamations (e.g., “what he could do”, “people can use”, “things they should do”, “What an interesting accident!”, “How lucky we are”). Then check and discuss. IV. Assessment of Teaching Effectiveness Assess Ss' understanding of modal verbs via answers in C1 and C2. Observe accuracy in forming exclamatory sentences (C4) and completing the invention passage (C5). Evaluate ability to use grammar points correctly in context. This lesson helps Ss master modal verbs and exclamations, improving grammatical accuracy in writing and speaking. V. Design Purpose Studying examples and grammar highlights introduces and explains modal verb and exclamation rules. Completing the patent card and exclamatory sentences practices application of rules. Completing the invention passage integrates grammar points into a meaningful text, reinforcing understanding and usage. VI. Blackboard Design Unit C Grammar “can, should, must & What/How …!” Modal verbs: can: possibility/permission/ability should: advice must: necessity Exclamatory sentences: What + a/an + adj + sing. countable noun + (S + V)! What + adj + uncountable/plural noun + (S + V)! How + adj/adv + (S + V)! Key practice: patent card, exclamatory sentences, invention passage. VII. Homework Write five sentences using “can”, “should”, “must” correctly. Write three “What” and three “How” exclamatory sentences about your day. VIII. Teaching Reflection The lesson effectively taught modal verbs and exclamations. Ss engaged in practice tasks. However, some struggled with choosing between “can” and “must” for necessity. More contextual examples on necessity vs. possibility can be provided in future lessons. 学科网（北京）股份有限公司 $$
