Have students look at the theme picture on Page41and discuss the guiding questions. 2. Invite some students to share their answers. 3. Ask students to predict what this unit might be about.1a 1. Present the six pictures and the list of invention names. 2. Ask students to work in pairs to match the names with the things in the pictures. 3. Have students guess or discuss:When do you think these things were invented? 4. Check the answers as a class.1b 1. Show students the two invention pictures (Super See and Smart Cook) and let them guess what these two inventions are used for. 2. Play the conversations. Let them choose the correct invention for each conversation and fill in the blanks for the countries. 3. Check the answers together. 1c 1. Play the conversations again. Students listen and circle T or F. 2. Check the answers with the class. For false statements,ask: What is the correct information?1d 1. Put students into pairs. Ask them to use the information from the listening and the sentence patterns below to describe each invention.2. Write on the board for support: What it looks like: It looks like .../They look like ... What it is used for: It is used for .../They are used for ... /It can help people to …. How it works: You put...then press ../A camera is connected to .. 3.Give an example: Super See looks like a pair o f sunglasses. They are used for helping people who can't see well.A mini-camera is connected to them ... 4. Encourage students to discuss which invention they like better and invite 2-3 pairs to present their descriptions and opinions to the class. 5. Ask students: Can you think of one simple invention that could make our school life better? What does it look like? What is it used for? Let them brainstorm and share ideas.Summary Ask students to summarize what they have learned in this lesson. Blackboard Design Write the language points and useful expressions on the blackboard.The lesson successfully introduced inventions and the passive voice through engaging dialogues. Students participated actively in listening and description tasks. The main challenge for them was organizing coherent descriptions and expanding ideas due to limited background knowledge about specific inventions. Next time, I will provide stronger scaffolding and encourage practice with more familiar ,everyday inventions first.Show students a picture of “the International Exhibition of Inventions”and several photos of innovative products. Ask students: What do you see? Have you ever been to or heard about such an exhibition?Pre-teach or review key vocabulary from the listening by using images, including words such as invention ,exhibition,3D printer ,design,create ,produce ,material,and plastic.2a 1. Direct students to the questions. Ask them to read the questions carefully before listening. 2. Play the audio. Ask them to listen for the answers to the two questions. 3. Check the answers with the class. 2b 1.Have students look at the sentences and the verbs in the box. Ask them to complete the sentences with the correct forms of the verbs. 2. Play the audio again. Ask them to check the answers. 3.Highlight the passive voice structure and explain its use. 2e 1. Play the audio for the third time. Have students tick the things they hear that a 3D printer can make. 2. Check the answers. Then,ask students:What else do you know that a 3D printer can make? to extend the topic.2d 1. Ask students to individually list a few things they use every day and choose one that is the most useful for their lives. 2. In pairs,have them talk about what the invention looks like and what it is used for. 3. To model the activity, present a short sample dialogue using the framework provided: A :What invention do you like the most ? B:I like my smartphone the most. A:Why? B:Because it's very useful. It looks like a small flat rectangle with a big screen. It is used for communication, getting information ,taking photos ,and many other things. 4. Invite a few pairs to share their conversations with the class.Summary Ask students to summarize what they have learned in this lesson. Blackboard Design Write useful expressions and important language points on the blackboard.This lesson successfully integrated listening comprehension with grammar (passive voice) in a relevant context. Students were engaged by the topic of innovative inventions. For future lessons,providing a clearer visual or diagram of the 3D printing process before the detailed listening could aid comprehension of the sequence.The teacher asks students to think about and share what they think is the most useful invention in their daily lives and why.3a 1. The teacher directs students to the question in 3a and asks them to skim the conversation to find the answer. 2.Students then read the conversation again more carefully to understand Peter's reasons and the supporting facts about the radio.3b 1. Students work individually or in pairs to review the conversation and complete the fact chart with the required information. 2. The teacher checks the answers with the class, ensuring the information is accurately extracted. 3c 1. The teacher plays the audio of the conversation,asking students to pay attention to how key information is stressed in natural speech. 2. Students then practise the conversation in pairs,trying to imitate the stress and intonation to make their role-play more fluent and expressive.3d 1. In pairs or small groups, students choose another invention they believe is important. They create a simple mind map to organize information about it (e. g, name,inventor, date,key features,impact). 2.Using their mind maps as a guide, students take turns describing their chosen invention to their partner. The teacher can provide a sentence framework on the board (e. g. I think the most important invention is ... It was invented by ... around ... It changed the world by .…. ).Summary Ask students to summarize what they have learned in this lesson. Blackboard Design Write useful expressions and language points on the blackboard.The lesson successfully guided students from extracting factual information about an invention to practising oral presentation skills. The mind map activity effectively scaffolded the challenging task of organizing and giving a description. For students who struggled with generating ideas for 3d, providing a list of inventions to choose from next time could lower the cognitive load and allow more focus on language production.1. Write two example sentences on the blackboard for comparison: Active:People connect a camera to the glasses. Passive:A camera is connected to the glasses. 2. Ask students:What is the difference?Which sentence focuses on the person doing the action,and which focuses on the thing (the camera)? Guide them to notice the form and focus on the passive voice.4a 1. Have students read the four sentences in the box and circle the verbs in the passive voice. 2. Guide students to observe and summarize the structure they see. Ask: What two parts do all the circled verbs have?(Guide them to see: be+past participle) What is the difference between the first two and the last one? (Guide them to notice present vs. past tense of the verb “be”).1.什么是被动语态(Passive Voice)? 当句子的主语是动作的发出者用主动语态,当句子的主语是动作的承受者(即某事被做) 时,使用被动语态。它的作用是强调动作本身或承受者，而不是执行者。 基本结构:主语十be动词十动词过去分词(十by+动作执行者). 2.被动语态的构成与时态3.主动语态与被动语态的转换 (1)把主动句的宾语变成被动句的主语。 (2)根据新主语的数和时态,选用正确的be+过去分词。 (3)将主动句的主语放在by后面(若需指出)。例如: Millions of people use smartphones every day.→Smartphones are used by millions of people every day. Chinese engineers completed the Qinghai-Xizang Railway in 2006.→The Qinghai-Xizang Railway was completed by Chinese engineers in 2006. Scientists might discover new energy sources in the future. →New energy sources might be discovered by scientists in the future.4b 1. Ask students to complete the sentences with the correct passive forms of the verbs in brackets. 2. Remind them to first determine the tense (past or present) and the subject (singular or plural) to choose the right form of “be". 3. Check the answers as a class and briefly discuss the meaning of each sentence. 4c 1. Have students read the passage about the Qinghai-Xizang Railway. 2. Ask them to complete the blanks with the correct forms of the verbs in brackets. Remind them to look at the subject of each sentence to decide whether the verb should be in the active or passive voice. 3. Check the answers together.Summary Ask students to summarize what they have learned in this lesson. Blackboard Design Write the grammar rules on the blackboard.The lesson systematically introduced the passive voice with clear examples from the unit theme. Students successfully identified and formed passive structures in controlled exercises. The passage completion activity effectively contextualized the grammar. Overall, this lesson successfully reached its objectives.1a 1.Show students pictures of various everyday objects made from different materials.Ask them to identify what each object is made of. 2. Direct students to activity la. Have them discuss in pairs to find more examples of things made from the materials shown, activating prior knowledge about materials.1b 1. Have students look at the title of the text and predict what invention the text will be about and how it might have changed the world. 2. Instruct students to skim the text to match each paragraph with its corresponding topic. 3. Check the answers with the class. Ask students to point out the key sentence in each paragraph that helped them decide.1c 1. Guide students to the activity following the text. Explain that identifying what pronouns refer to helps understand how ideas are connected. 2. Ask students to read the text again carefully to find out what the bolded pronouns refer to in the context. 3. Check the answers with the class and discuss how these reference words create cohesion between sentences and paragraphs. 1d 1. Direct students to the table comparing writing materials before and after Cai Lun. 2. Have them scan related paragraphs to complete the information in the table. Remind them to use concise phrases and key words. 3. Check the answers with the class. 1e 1. Ask students to locate the paragraph that describes the paper making process. 2. Have them read the four sentences and put them in the correct chronological order based on the description in the text. 3. After checking the correct order,instruct students to retell the process in their own words,encouraging them to use sequence markers such as First,Then, Next, After that , and Finally.lf 1. Organize students into small groups to discuss the questions. 2. Invite a few groups to share their ideas with the whole class. Guide the discussion to connect the qualities mentioned (e.g.curiosity, persistence,creativity,observation ) back to Cai Lun's story and other inventors they know.2a 1. Have students work individually or in pairs to complete the table with the correct noun, verb, and adjective forms of the given words. 2. Encourage them to add more related words they know.2b 1. Ask students to read each sentence and choose the correct word to complete it,focusing on the meaning. 2. Check the answers together,clarifying the meaning and usage of key words. 2c 1. Instruct students to complete the passage about the invention of sticky notes using the correct forms of the phrases in the box. 2. After checking the answers, facilitate a brief class discussion on the question: How is an invention like sticky notes turned from an idea into reality? Link it to the process described in the main text.Summary Ask students to summarize what they have learned in this lesson. Blackboard Design Write the useful expressions and language points on the blackboard.This lesson successfully engaged students with a historically and culturally significant topic. The reading tasks effectively scaffolded comprehension from gist to detailed analysis, with the pronoun reference activity being particularly useful for understanding textual cohesion. For future lessons ,providing a short video or more visual aids about the papermaking process will be helpful.1. The teacher begins by asking the class one open question: Think of one invention that changed the world.What problem did it solve , or what dream did it help to come true? Give students a moment to think,and then quickly invite 2-3 volunteers to share simple answers. (E.g. The light bulb--it ended darkness at night./The refrigerator-it solved the problem o f keeping food fresh. ) 2. After briefly acknowledging their ideas, the teacher connects to the lesson: Every invention has a story of a problem and a solution. Today,we'll read the story of a world-changing invention-the airplane.3a 1. Direct students to the text about the invention of the airplane. Ask them to read it carefully and complete the chart that follows. 2. Have students underline the key sentences that answer each question in the chart. 3. Review the answers as a class to ensure comprehension and highlight the text structure, 3b 1. Guide students to the note-making framework below the chart. Their task is to choose one invention they are interested in and use the prompts to make research notes. 2. The teacher can provide a short fact sheet with key information about 3-4 common inventions. The students can also rely on their prior knowledge and share ideas in pairs to complete their notes.3c 1. Ask students to write a short paragraph about the invention they have chosen, using their notes from 3b as the content. Remind them to use the airplane text as a model for overall structure and language. 2. Provide clear writing guidelines on the board: Paragraph 1(Introduction):What the invention is, who invented it, and the main reason/purpose for the invention. Paragraph 2 (Process):The main challenges and how the invention was invented ( key steps/materials). State when it was invented. Paragraph 3 (Effect):What the invention led to or how it changed things. Useful phrases/Sentence starters: The ... was invented by... The main challenge was.../They had difficulties in... They solved this by... It was made from... This invention led to...1. Organize students into small groups to share their passages. They can read their passages aloud or exchange them to read silently. 2. Encourage listeners to give one compliment and ask one question. 3. Invite 2-3 volunteers to share their passages with the whole class.Summary Ask students to summarize what they have learned in this lesson. Blackboard Design Write the structure of the passage and useful expressions on the blackboard.This lesson effectively guided students from reading comprehension to structured writing. The clear,step-by-step framework helped students organize their ideas. The peer-sharing activity boosted confidence. For future lessons, preparing a visual list of common inventions with key facts could help students who struggled with the research step to get started more quickly.
