Unit 7 The secret of memory-Section 2 Exploring and applying rules (Grammar) This unit focuses on the topic of "memory". In this grammar section, students will mainly learn about conditional adverbial clauses guided by "if" and "unless". Conditional adverbial clauses are used to express the relationship between conditions and results. By studying this grammar point, students can better understand and express conditional relationships in English, which will improve their language accuracy and expressiveness in both speaking and writing. The content is closely related to the theme of memory in this unit, and will be combined with examples related to memory to help students understand and apply the grammar knowledge. 教学目标 Students will be able to understand the structure and usage of conditional adverbial clauses led by "if" and "unless". Students will master the tense usage in conditional adverbial clauses, especially the first conditional (present simple in the if - clause and will + base form in the main clause). Students will be able to distinguish the meanings and usages of "if" and "unless". 教学重难点 1 Key Points The structure and basic usage of conditional adverbial clauses with "if" and "unless". The correct choice of tenses in conditional adverbial clauses. For example, in the first conditional, using the present simple tense in the "if" - clause to express a possible condition in the present or future, and using "will + base form" in the main clause to express the result. Understanding the meaning and difference between "if" (expressing a positive condition) and "unless" (equivalent to "if... not", expressing a negative condition). 2 Difficult Points Mastering the flexible application of conditional adverbial clauses in different contexts, such as making sentences that conform to logical and semantic requirements. Helping students avoid common mistakes in the use of tenses in conditional adverbial clauses, such as wrongly using the future tense in the "if" - clause. Distinguishing some complex sentence patterns that contain conditional adverbial clauses and understanding their overall meanings. 1 Conditional Adverbial Clauses with "if" Structure: If + present simple tense, subject + will + base form. For example, "If you study hard, you will get good grades." Here, "If you study hard" is the conditional clause, expressing a possible condition, and "you will get good grades" is the main clause, expressing the result that will happen under this condition. The "if" - clause can be placed at the beginning or at the end of the sentence. When it is placed at the beginning, a comma is usually used to separate it from the main clause. When it is placed at the end, no comma is needed. For example, "You will get good grades if you study hard." Meaning: It is used to describe a situation where a certain condition needs to be met first, and then a corresponding result will occur. The condition expressed by the "if" - clause is possible in the present or future. 2 Conditional Adverbial Clauses with "unless" Structure: Unless + present simple tense, subject + will + base form. For example, "Unless you get enough sleep, you will be tired tomorrow." "Unless you get enough sleep" is the conditional clause, and "you will be tired tomorrow" is the main clause. Similar to the "if" - clause, the "unless" - clause can also be placed at the beginning or end of the sentence. When at the beginning, use a comma; when at the end, no comma. For example, "You will be tired tomorrow unless you get enough sleep." Meaning: "Unless" means "if... not". The above example "Unless you get enough sleep, you will be tired tomorrow." can be rewritten as "If you don't get enough sleep, you will be tired tomorrow." It emphasizes a negative condition, that is, if a certain condition is not met, a certain result will occur. 3 Tense Usage in Conditional Adverbial Clauses In the first conditional, which is used to talk about real - possible situations in the present or future: The "if" or "unless" - clause uses the present simple tense to describe the condition. This is because we are talking about a general condition that may exist now or in the future. For example, "If it rains tomorrow, we will stay at home." Here, "rains" in the "if" - clause is in the present simple tense although the action will happen tomorrow. The main clause uses "will + base form" to express the result that will happen as a consequence of the condition. In the example above, "will stay" in the main clause indicates the future result. 教学过程 1 Lead - in (5 minutes) Greet the students and start the class. Show some pictures related to memory, such as a student forgetting to bring his homework (picture 1) and a student getting a high score because he reviews carefully (picture 2). Ask students: "Look at these pictures. Can you guess what will happen if a student forgets to bring his homework? And what will happen if a student reviews carefully?" Encourage students to answer in English. Through this way, lead students to think about conditional relationships and introduce the topic of conditional adverbial clauses. 2 Presentation (10 minutes) Write two simple sentences on the blackboard: "You study hard. You will get good grades." Then combine them into a conditional sentence: "If you study hard, you will get good grades." Explain the structure of the conditional adverbial clause with "if" to students: the "if" - clause (expressing the condition) uses the present simple tense, and the main clause (expressing the result) uses "will + base form". Give more examples like "If you eat too much junk food, you will get fat." and ask students to analyze the structure. Next, introduce the conditional adverbial clause with "unless". Write the sentence "You won't pass the exam if you don't study hard." on the blackboard, and then rewrite it as "Unless you study hard, you won't pass the exam." Explain the meaning and structure of "unless" - clauses. Emphasize that "unless" means "if... not". Provide more examples such as "Unless you put the book back on the shelf, the teacher will be angry." and let students understand the usage. 3 Practice (15 minutes) Oral Practice Divide students into pairs. Give each pair a set of cards. On each card, there is a condition or a result. For example, one card says "If you get up late" and another card says "you will be late for school". Students need to match the cards and make conditional sentences. Then, they take turns to read out the sentences they made. Walk around the classroom to monitor and offer help if necessary. After that, ask some pairs to come to the front of the class and share their sentences with the whole class. Written Practice Hand out a worksheet to students. The worksheet contains a series of exercises about conditional adverbial clauses. The first part is to complete the sentences with the correct form of the verbs in brackets. For example, "If he ______ (come) tomorrow, we will go to the park." The second part is to rewrite the sentences using "unless". For example, "If you don't wear warm clothes, you will catch a cold." (Rewrite it with "unless"). Give students about 8 minutes to finish the written exercises. Then, go through the answers together, explain the reasons for each answer, and correct students' mistakes. 4 Group Activity (10 minutes) Divide students into groups of four. Assign each group a topic related to memory, such as "How to improve memory". Ask each group to make a short passage about the topic using conditional adverbial clauses. For example, "If you want to improve your memory, you should review regularly. Unless you repeat what you have learned, you will forget it quickly." Each group members discuss and write the passage together. One member in each group is responsible for writing down the group's ideas on a piece of paper. After 8 minutes, ask each group to present their passage to the class. Other groups listen carefully and can ask questions or give suggestions. 5 Summary and Homework (5 minutes) Summarize the key points of this class, including the structure and usage of conditional adverbial clauses with "if" and "unless", and the tense usage. Review some common mistakes students made in the exercises and remind them to pay attention. Assign homework: Ask students to write five conditional sentences using "if" and five using "unless" on their own, related to their daily life or study. Ask students to find some conditional sentences in English articles they read or English movies they watch and write them down in their notebooks. 教学反思 After this class, generally, students showed a certain level of interest in the topic of conditional adverbial clauses, especially when starting with the lead - in related to memory pictures, which effectively attracted their attention. In the presentation part, most students could understand the basic structure and meaning of "if" and "unless" conditional adverbial clauses through examples and explanations. However, during the practice and group activity, some problems emerged. In the oral practice, a few students still had difficulties in quickly matching the conditions and results and making correct sentences. This may be due to their insufficient familiarity with the vocabulary and the sentence structure. In the written practice, common mistakes included wrong verb tenses in the "if" - clause, such as using "will + base form" instead of the present simple tense. Also, when rewriting sentences with "unless", some students made logical errors. During the group activity, although students actively participated in the discussion, the quality of the passages varied. Some groups could use conditional adverbial clauses accurately and vividly to express their ideas, while some groups had problems with grammar and sentence coherence. In future teaching, more targeted exercises should be designed to strengthen students' understanding and application of verb tenses in conditional adverbial clauses. Also, more individual guidance should be provided during group activities to ensure that every student can actively participate and improve their English ability. In addition, more real - life examples and interactive games can be added to further enhance students' interest and proficiency in using conditional adverbial clauses. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
