教学目标理解并掌握比较级的构成规则能在实际情境中正确使用比较级理解并运用比较级的修辞功能教学内容1. 比较级的定义和形式比较级是用来比较两个或多个事物之间的关系的词或词组。通常形式为形容词或副词的比较级。例如：happier，more beautiful，faster。2. 比较级的规则变化大多数形容词和副词都有比较级，但有一些词是没有比较级的，如：perfect，unique，eternal等。3. 比较级的用法我们可以使用比较级来描述我们更喜欢的事物，或者在两个事物之间进行比较。在英语中，我们通常会使用“than”这个词来引导比较的对象。例如：“I like apples more than pears.”（我喜欢苹果胜过梨。）教学步骤Step 1: 导入新课Activity: Ask students to compare two things in the classroom and use the comparative form of the adjective to describe them. For example, "The blackboard is bigger than the whiteboard."Step 2: 新知识讲解Presentation: Show students the rules for forming the comparative form of adjectives and adverbs. Use examples to illustrate the usage.Explanation: The comparative form of most adjectives and adverbs is formed by adding "-er" to the end of the word, or by adding "more" before the word. However, some words have irregular comparative forms. For example, "good" becomes "better," and "bad" becomes "worse."Step 3:实践活动Activity: Have students work in pairs. Ask each pair to compare two things and use the comparative form of the adjective or adverb to express their opinion. For example, "The blue shirt is more beautiful than the red shirt."Step 4: 课堂互动Activity: Have a class discussion on which of two things is better. For example, ask students whether they prefer to study in a group or alone, or which of two subjects they find more interesting. Encourage them to use the comparative form of the adjective or adverb to express their opinion.Step 5: 课堂小结Conclusion: Remind students of the rules for forming the comparative form of adjectives and adverbs, and the usage of the comparative form in expressing preferences between two things. Encourage them to use the comparative form correctly in their daily life.Step 6: 课后作业Homework: Ask students to write a short paragraph comparing two things of their choice, using the comparative form of the adjective or adverb throughout the paragraph.
