教材分析
What---语篇主题和主要内容 Topic: How can we use exclamatory sentences and modal verbs to express feelings and talk about rules Main content: This lesson focuses on two grammar points: exclamatory sentences (What...! / How...!) and modal verbs (can, should, must). It begins with students studying example sentences to discover the structures of exclamatory sentences and the meanings of the three modal verbs (C1, C3). Next, students learn the grammar rules through the Grammar highlights, including the structures of What/How sentences and the usage of can (ability/possibility/permission), should (advice), and must (necessity/rules), as well as their negative forms. Then, students complete grammar exercises to practice using these structures in context (C2, C4, C5). Finally, students apply the target grammar to describe small inventions and express their feelings. Why---语篇传递的主题意义 Core values conveyed: 1. Understanding the function of exclamatory sentences — Students learn that What/How sentences are used to express strong feelings such as surprise, excitement, or admiration. 2. Developing the ability to express feelings and opinions — Students learn to use exclamatory sentences to express their feelings about inventions and use modal verbs to give advice or talk about rules. 3. Understanding the importance of rules and advice — Students learn to use can, should, and must to talk about ability, give suggestions, and state rules in real-life contexts. 4. Building awareness of innovation — Students realize that inventions solve problems in our daily life, and they can express their appreciation for inventions using the target grammar. 5. Fostering critical thinking — Students learn to evaluate and express their own opinions about inventions and inventors with reasons. How---文体结构、语言特点及功能 1. Text structure The lesson follows a clear "Observe → Learn → Practice → Apply" structure: C1 & C3: Observe example sentences to discover the rules of modal verbs and exclamatory sentences. Grammar highlights: Learn the structures of What/How sentences and the usage of can, should, and must. C2: Complete an information card about patents using can/can't, should, and must. C4: Complete sentences by changing statements into exclamatory sentences. C5: Complete a passage about a small invention with the target words (can, should, must, what, how). 2. Language features Target grammar: Exclamatory sentences (What + a/an + adj. + singular countable noun! / What + adj. + uncountable/plural noun! / How + adj./adv. + subject + verb!) and modal verbs (can, should, must and their negative forms). Target vocabulary: earmuffs, solve, should, patent, invention, in fact, sticky note, final, apply for a patent, do research. Authentic context: The grammar is embedded in real-life contexts such as libraries, patents, and small inventions, making it practical and meaningful. 3. Language functions Expressing strong feelings: Students learn to use What/How sentences to express surprise, excitement, or admiration (e.g., "What a clever idea!" / "How fast the rocket travels!"). Talking about ability and permission: Students learn to use can to say that something is possible or allowed, or that somebody has the ability to do something (e.g., "You can turn on the air conditioner."). Giving advice: Students learn to use should to say that something is a good thing or the right thing to do (e.g., "We should make more use of green energy."). Talking about rules and necessity: Students learn to use must to say that something is necessary or very important, sometimes a rule or a law (e.g., "We must be very quiet in the library."). Using negative forms: Students learn to use cannot (can't), should not (shouldn't), and must not (mustn't) correctly in sentences.
学情分析
【已知】Students have learned some basic modal verbs in primary school, such as can to express ability (e.g., "I can swim.") and can/can't to express permission or possibility. They are also familiar with basic exclamatory expressions like "How nice!" or "What a pity!" in everyday communication. They can understand and use simple sentences with the simple present tense and the simple past tense to describe facts and past events. They are also familiar with basic reading skills, such as scanning for specific information and understanding short stories about everyday life. 【未知】Students do not know how to use exclamatory sentences (What...! / How...!) to express strong feelings like surprise, excitement, or admiration. They may struggle to distinguish between What and How by identifying the headword (noun vs. adjective/adverb). They cannot yet use the modal verbs can, should, and must correctly to talk about ability, advice, and rules, especially their negative forms (can't, shouldn't, mustn't). Additionally, they lack the ability to apply these grammar points in real-life contexts to describe inventions or express opinions. 【能知】 Through studying example sentences (C1, C3), learning the grammar rules (Grammar highlights), and completing grammar exercises (C2, C4, C5), students will be able to: 1. Use What...! and How...! sentences correctly to express strong feelings like surprise, excitement, or admiration. 2. Tell the difference between What and How exclamatory sentences by identifying the headword. 3. Master the usage of can (ability/possibility/permission), should (advice), and must (necessity/rules). 4. Use the negative forms can't, shouldn't, and mustn't correctly in sentences. 5. Apply the target grammar to complete sentences and describe small inventions in real-life contexts.

教学反思
亮点：1. The lead-in activities effectively aroused students' interest through a video about "What... / How..." exclamatory sentences and a discussion about feelings, naturally introducing the target grammar of expressing strong emotions. 2. In the grammar teaching section, through the comparison of example sentences in C1 and C3, students intuitively understood the differences between modal verbs (can, should, must) and exclamatory sentences (What/How...!), and were able to summarize the rules independently. 3. The grammar fill-in-the-blank exercise in C2 was very successful. Students mastered the usage of modal verbs in a real context (the patent information card), which improved their grammar application ability. 4. The sentence transformation and gap-fill exercises in C4 and C5 worked well. Students were able to correctly change statements into exclamatory sentences and use the target grammar to complete the passage about a small invention. 不足：1. Some weaker students still had difficulty distinguishing between "What" and "How" exclamatory sentences and confused the headword (noun vs. adjective/adverb). 2. Due to limited class time, some groups did not have enough time to fully present their answers in the C5 gap-fill and the Summary section, which affected the training of language output. 3. In the grammar application section, although some students could complete the mechanical exercises correctly, their ability to flexibly use the target grammar in real-life contexts still needed improvement. 改进： 1. Provide more comparison exercises and visual charts in the grammar analysis section to help weaker students intuitively understand the difference between "What" and "How." 2. Optimize class time management by simplifying the C5 exercise and the Summary tasks or assigning them as extended homework, ensuring sufficient time for presentation and feedback in class. 3. Provide more real-life contexts and sentence frames in the grammar application section to guide students in using the target grammar flexibly in real communication.
