六、教学过程
StepⅠ Lead-in
Topic introduction
Lead in the topic: Today we will learn three basic sentence structures in English: simple sentences, compound sentences and complex sentences.
Present several short sentences related to teenagers’ life on the screen, and ask students to read them aloud.
（设计意图：开门见山点明本节课语法主题，结合青少年相关例句引入内容，快速将学生带入课堂学习状态。）
Step Ⅱ Presentation
Present the title: Simple, compound and complex sentences.
Show the definition and classification of simple sentences. Explain the five basic sentence patterns one by one, and provide explanations for each pattern with examples.
S + V
S + V + P
S + V + O
S + V + IO + DO
S + V + O + OC
Move on to compound sentences. Explain its definition, then classify compound sentences according to logical relations, introduce corresponding conjunctions and matching examples.
Parallel relationship: and, both…and…, not only…but also…, neither…nor…
Contrast relationship: but, yet, while
Choice relationship: or, either…or…, otherwise, or else
Cause and effect: so, therefore, for
Explain complex sentences. State its definition, the relationship between main clauses and subordinate clauses, and introduce adverbial clauses and object clauses with typical examples.
（设计意图：严格按照课件顺序依次呈现三类句式，结合课件原句讲解知识点，由浅入深搭建语法知识框架，让学生系统掌握核心语法概念与结构。）
Step Ⅲ The Usage and Functions
Reiterate the core usage of simple sentences: One independent clause with only one subject-verb combination, five fixed basic structures for different expression needs.
Sum up the usage rules of compound sentences: Two or more independent main clauses, connected by coordinating conjunctions to show different logical meanings. Remind students that for cannot be used at the beginning of a sentence.
Analyze the usage of complex sentences: One main clause plus one or more subordinate clauses. Subordinate clauses act as different sentence elements and cannot exist alone. Master the usage of conjunctions in adverbial clauses and object clauses.
Guide students to distinguish the differences between compound sentences and complex sentences.
（设计意图：深度梳理三类句式的功能、用法与使用注意事项，对比易混知识点，帮助学生理清知识边界，突破本节课重难点内容。）
Step Ⅳ Practice
Activity 1: Sentence classification

Simple sentences: (2) (3) (4) (6)
Compound sentences: (5) (8) (13)
Complex sentences: (1) (7) (9) (10) (11) (12)

Activity 2: Fill in the blanks
Ask students to complete the passage about sentence rules according to what they have learned.
Check answers: (1) and (2) but
Read the full passage together to review basic rules.

Activity 3: Join sentences
Present 5 groups of separate sentences. Require students to combine them into compound sentences or complex sentences.
Students finish the exercise independently.
Check answers and explain the conjunctions used in each sentence.

九、教学反思
本节课围绕三大句式展开教学，依托青少年生活、亲子交流、健康网站等语境讲解语法，内容贴合学生认知，多数学生能够掌握三种句式的基础定义与分类，顺利完成基础练习题，课堂基础目标达成。但教学中仍存在不足：
部分学生对并列句和复合句的界限分辨不清，在定语从句、主语从句的句型转换练习中失误较多；
本节课以笔头练习为主，口语输出活动偏少，学生缺少口头运用多样句式的机会；
课堂写作练习时间有限，句型仿写的训练量不够，缺少长难句分析、高阶写作类拓展任务。
