Unit 6 Great minds-C Grammaring This lesson in Unit 6 "Great minds" focuses on the grammar part. The main grammar points in this unit revolve around the use of modal verbs to express ability, possibility, permission, and obligation in the context of discussing great minds and their achievements. Students will learn how to correctly use modal verbs such as "can", "could", "may", "might", "must", etc. and understand the differences in their meanings and usages. For example, they will distinguish between "can" for present ability and "could" for past ability or polite requests. Through various examples and exercises related to great inventors, scientists, and thinkers, students will get familiar with applying these modal verbs in different sentence structures. 教学目标 A. Knowledge Objectives Students will be able to understand the functions and usage rules of modal verbs, including expressing ability, permission, possibility, and obligation. Master the correct forms of modal verbs in affirmative, negative, interrogative sentences, and their short answers. Distinguish the differences in meaning and usage among similar modal verbs, such as "can" and "could", "may" and "might". B. Ability Objectives Be able to use modal verbs accurately to describe the abilities, possibilities, permissions, and obligations of great minds in different historical periods in speaking and writing. Improve students' reading and listening comprehension skills by understanding texts and dialogues containing modal verbs. Develop students' ability to analyze and solve grammar - related problems through exercises and group discussions. C. Emotional Objectives Stimulate students' interest in learning grammar through the exploration of great minds' stories related to modal verbs. Cultivate students' sense of curiosity and admiration for great minds, inspiring them to strive for knowledge and innovation. 教学重难点 A. Key Points The basic usage of modal verbs: "Can" is used to express present ability, e.g., "Thomas Edison can invent many useful things." It is also used for requests and offers in informal situations, like "Can you pass me the book?" "Could" is the past form of "can", expressing past ability, such as "When he was young, Einstein could already show great talent in physics." It can also be used to make polite requests in the present, for example, "Could you help me with my homework?" "May" is used to express permission (less formal than "can" in some cases) and possibility, e.g., "May I use your pen?" and "It may rain tomorrow." "Might" is the past form of "may" in some cases, and it also expresses a weaker possibility, like "He might come to the party tonight, but I'm not sure." "Must" is used to express obligation and strong probability, for instance, "We must respect the great minds who have made contributions to society." and "He must be at home because his car is in the driveway." The formation of affirmative, negative, interrogative sentences, and short answers with modal verbs. For example: Affirmative: He can speak English well. Negative: He can't speak English well. Interrogative: Can he speak English well? Yes, he can. / No, he can't. B. Difficult Points Distinguishing between modal verbs with similar meanings, especially the subtle differences in expressing possibility. For example, the difference between "may" and "might", where "might" usually indicates a more uncertain or less likely possibility. Using modal verbs correctly in complex sentence structures and different tenses. For example, in conditional sentences like "If I could go back in time, I would meet Leonardo da Vinci." Modal Verbs and Their Meanings Can (Present Ability): Definition: Expresses the ability to do something in the present. Example: Alexander Graham Bell can invent the telephone because of his great knowledge and perseverance. Could (Past Ability / Polite Request): Definition (Past Ability): The past form of "can", indicating the ability to do something in the past. Example: When Isaac Newton was a student, he could solve very difficult math problems. Definition (Polite Request): Used to make polite requests in the present. Example: Could you tell me more about Albert Einstein's theory of relativity? May (Permission / Possibility): Definition (Permission): Used to ask for or give permission, a bit more formal than "can" in some cases. Example: May I visit the museum to see the inventions of great minds? Definition (Possibility): Expresses a possibility. Example: It may be challenging to understand some of the complex ideas of great philosophers. Might (Weaker Possibility): Definition: Expresses a weaker possibility compared to "may". Example: A new great mind might emerge in the future and change the world with new inventions. Must (Obligation / Strong Probability): Definition (Obligation): Indicates that something is necessary or required. Example: We must learn from the spirit of great minds and work hard to achieve our goals. Definition (Strong Probability): Expresses a high degree of certainty. Example: The scientist has been working hard on the experiment. He must have made some progress. Sentence Structures with Modal Verbs Affirmative Sentences: Subject + Modal Verb + Base Verb + Object. Example: Nikola Tesla can create amazing electrical inventions. Negative Sentences: Subject + Modal Verb + Not + Base Verb + Object. Example: We can't underestimate the contributions of great minds in history. Interrogative Sentences: Modal Verb + Subject + Base Verb + Object? Example: Can you name some great female scientists in history? Short Answers: For "Can": Yes, + Subject + can. / No, + Subject + can't. For "Could": Yes, + Subject + could. / No, + Subject + couldn't. For "May": Yes, + Subject + may. / No, + Subject + may not. For "Must": Yes, + Subject + must. / No, + Subject + needn't (when "must" means obligation, the negative answer uses "needn't" to mean "not necessary"). 教学过程 A. Warming - up (5 minutes) Greet the students and show some pictures of well - known great minds, such as Archimedes, Galileo, and Marie Curie. Ask students to briefly describe what they know about these great minds in English. T: Good morning/afternoon, class. Look at these pictures. Who can tell me something about Archimedes? S: Archimedes is a famous ancient Greek scientist. He discovered many important scientific principles. Then, lead in the topic of modal verbs by asking questions like "Do you think you can be as great as them in the future? Can you imagine what you could do if you had the chance to live in their time?" B. Presentation (15 minutes) Use the pictures of great minds to introduce the usage of "can" and "could". For "can" (present ability): T: Look at Thomas Edison. He is very intelligent and hard - working. He can invent many useful things, like the light bulb. Now, you try to make a sentence using "can" to describe a great mind's ability. S: Albert Einstein can understand and explain very complex scientific theories. For "could" (past ability): T: When Alexander Graham Bell was young, he showed great interest in sound. As he grew up, he could invent the telephone. Can you give an example using "could" to talk about a great mind's past ability? S: When Leonardo da Vinci was a child, he could draw very well. Present the usage of "may" and "might" through examples related to great minds' achievements and possibilities. For "may" (permission and possibility): T: Suppose you are a researcher in a science museum. You want to study the original notes of a great scientist. You can say, "May I study the original notes of [a great scientist]?" Also, think about this: The discovery of a new scientific theory may change our understanding of the world. Now, make a sentence using "may". S: May I borrow the books about great inventors from the library? / A new invention may improve our daily life. For "might" (weaker possibility): T: We are not sure if a new great mind will emerge in a small town, but it might happen. Make a sentence with "might". S: A young student in our school might become a great inventor in the future. Explain the usage of "must" in the context of great minds. For "must" (obligation): T: We all know that great minds have made great contributions to society. So, we must respect their achievements. Can you give an example using "must" to show an obligation related to great minds? S: We must learn from the spirit of great inventors and work hard. For "must" (strong probability): T: Look at this scientist. He has been in the laboratory for a long time. He must be doing an important experiment. Make a sentence with "must" to express strong probability. S: The professor has published many papers. He must be very knowledgeable. C. Practice (15 minutes) Oral Practice Divide the students into pairs. Provide each pair with a set of cards. On each card, there is a situation related to great minds. For example, "You want to ask your teacher if you can do a project about a great female scientist", "You are guessing what a great inventor might be thinking when he was working on his invention", etc. The students need to make sentences using the appropriate modal verbs according to the situations on the cards and practice the dialogues. Monitor the pairs and offer help when necessary. After a few minutes, invite some pairs to come to the front of the class and act out their dialogues. Written Practice Hand out a worksheet with grammar - filling exercises. The exercises are designed around the usage of modal verbs in the context of great minds. For example: Thomas Edison __________ (can) invent the phonograph because of his creativity. (Answer: could) __________ (May / Must) I visit the 故居 of Newton this weekend? (Answer: May) A great philosopher __________ (might / must) have a deep understanding of human nature. (Answer: must) Let the students complete the exercises individually. Then, go through the answers together, explaining the reasons for each choice. D. Production (5 minutes) Ask the students to write a short passage about a great mind they admire. In the passage, they need to use at least three different modal verbs to describe the great mind's abilities, possibilities, and the obligations we have towards learning from them. T: Now, it's your turn to show what you have learned. Write a short passage about a great mind you like best. Remember to use modal verbs such as "can", "could", "may", "might", "must". After the students finish writing, ask some of them to read their passages aloud to the class. Give positive feedback and praise for their good usage of modal verbs. E. Summary and Homework (5 minutes) Summary Review the key points of modal verbs with the students, including their meanings and usage rules. Emphasize the importance of using modal verbs correctly in different situations related to great minds or other topics. T: Class, today we have learned about the usage of modal verbs in the context of great minds. Can you tell me the main functions of "can", "could", "may", "might", and "must"? Ss: "Can" for present ability, "could" for past ability and polite requests... Homework Ask the students to find more information about a great mind they are interested in. Write a longer composition (about 100 - 120 words) using modal verbs to describe the great mind's life, achievements, and the inspiration we can get from him/her. Encourage the students to watch documentaries or read books about great minds in their spare time to improve their English and gain more knowledge. 教学反思 Positive Aspects The use of pictures of great minds in the warming - up and presentation stages effectively attracted students' attention and made the learning of modal verbs more interesting and relevant. It helped students better understand the application of modal verbs in real - life - like situations related to great minds. The pair - work and group - work activities in the practice stage provided students with sufficient opportunities to practice speaking and using modal verbs. Most students actively participated in the dialogues and showed good understanding and application of the grammar points. The production stage, where students wrote short passages, allowed them to integrate what they had learned and express their own ideas, which enhanced their writing ability and overall language proficiency. Areas for Improvement Some students still had difficulty distinguishing between "may" and "might" when expressing possibility. In future lessons, more specific exercises and examples focusing on this difference could be provided. The time for students to share their written passages in the production stage was a bit limited. Next time, more time should be allocated to ensure that more students have the chance to present and get feedback. For some weaker students, the grammar - filling exercises might have been a bit challenging. In the future, more differentiated instruction could be considered, such as providing additional guidance or simpler exercises for those who need more help. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
