长句复习  教案

 

教材分析

本节课是人教版（2019）选择性必修第四册 Unit 5 Launching Your Career 的 Period 2 Discover Useful Structures，语法点为英语长句的综合复习，包括并列句、复合句和并列复合句三种基本结构。学生在前面几个单元已经接触过各种从句和连接词，但对长句结构的整体把握和连接词选择掌握不牢，也容易把并列句和复合句搞混。课本这部分以职业规划与大学生求职为载体，本节课紧扣单元职业规划主题，以武汉光谷就业与大学生求职为情境重新组织例句和练习，让学生在熟悉的语境中梳理三种长句的结构特征和连接词用法。

教学目标

1. 通过观察例句，归纳并列句、复合句、并列复合句的结构特征与连接词用法。

2. 在讲武汉光谷就业、大学生求职与职业规划的语境中正确识别和运用各种长句结构。

3. 区分三种长句类型的结构差异，体会连接词在句子中的逻辑连接作用。

教学重难点

重点：三种长句的结构特征与连接词选择，尤其是并列连词和从属连词的区分。

难点：① 并列复合句中并列连词与从属连词的配合使用；② 根据上下文逻辑选择正确的连接词。

 

Teaching Procedures

Step 1  Lead-in（约5分钟）

Teacher: Good morning, class. Today we're going to review long sentences. Let's start with some sentences about college students and job hunting in Wuhan. Look at the sentences and identify what type they are. Two minutes.

Look at the sentences about college students and job hunting in Wuhan, and identify the sentence types: compound, complex, or compound-complex.

1. The Optics Valley in Wuhan is home to thousands of tech firms, and it draws graduates from all over the country.

2. When seniors start their job hunt, many of them send dozens of application letters before landing an offer.

3. Although job hunting is stressful, most students stay hopeful, and they never give up halfway.

【设计说明】用学生自己天天经历的求职招聘话题引入，不急于讲规则，先让学生在熟悉的语境中感知三种长句的不同结构——并列句、复合句、并列复合句。三种类型先混个脸熟，为后面的归纳攒感性认识。

Step 2  Analyze and Identify（约15分钟）

Task 1  Identify the sentence types

Teacher: Now look at these sentences about Wuhan's job market. Identify whether each one is a compound sentence, a complex sentence, or a compound-complex sentence. Five minutes, then we check together.

1. Wuhan is home to over a million college students, and the city offers preferential policies to keep them after graduation.

2. When you walk around Guanggu Square on a weekend, you can see young interns hurrying back from nearby offices.

3. Many graduates choose to start their own business, but they soon find it harder than expected because running a firm is full of challenges.

4. Although the job market is highly competitive this year, students with practical skills still land good positions.

5. A lot of parents once wanted their children to be doctors or lawyers, but now they accept other career choices.

6. If you are interested in engineering, you can attend the spring job fair at HUST, where many tech giants set up booths.

【设计说明】这6句正好对应重点——第1、5句练并列句，第2、4、6句练复合句，第3句练并列复合句。先让学生独立判断，做完直接核对答案，把三种不同结构的长句都攒出来，为后面归纳做准备。这里重点突破“并列连词和从属连词的区别”。

Task 2  Find the conjunctions

Teacher: Good. Now look at the six sentences again. Underline all the conjunctions you can find. Then tell me: which are coordinating conjunctions (并列连词) and which are subordinating conjunctions (从属连词)? Discuss with your partner. Three minutes.

【设计说明】让学生通过观察自己判断过的句子，自己找出连接词并分类，比一条一条讲规则印象更深。学生自己找出来的规律，后面总结的时候更容易记住。这里重点引导学生看连接词：and, but, or是并列连词；when, because, although, if是从属连词——直接切入难点①“并列连词和从属连词的区分”。

Task 3  Complete the sentences with Chinese hints

Teacher: Now let's move on. Complete the following sentences according to the Chinese hints. Pay attention to the correct conjunctions. Four minutes.

1. 武汉光谷聚集了大量科技公司，每年春天都吸引成千上万毕业生去应聘。

The Optics Valley gathers many tech firms, ______ it draws thousands of graduates to job fairs every spring.

2. 当一名大学生开始做职业规划时，他通常会先做个性格测试。

______ a college student begins career planning, he usually takes a personality test first.

3. 尽管找工作压力不小，但多数学生还是乐观的，因为他们对未来有想法。

______ job hunting is stressful, most students stay optimistic ______ they have clear goals.

4. 如果你想进武汉的设计院工作，你可以先去实习，在那里你能跟着工程师学东西。

______ you want to work at a Wuhan design institute, you can take an internship first, ______ you can learn from senior engineers.

【设计说明】从单句识别过渡到汉语提示完成句子，难度稍升。第1句练并列连词，第2句练从属连词，第3句练两个连词配合，第4句练并列复合句。四个句子正好对应四种连接情况，学生写完就能感受到不同连接词的位置差异。

Step 3  Summarize（约10分钟）

Task 1  Summarize the three types of long sentences

Teacher: Now work with your partner. Based on the sentences we just read, summarize the three types of long sentences and their conjunctions. I give you two minutes to think, then we share.

• Compound sentence (并列句): 两个或多个独立分句，用并列连词连接

  并列连词: and, but, or, so, for, yet, nor

• Complex sentence (复合句): 一个主句 + 一个或多个从句，用从属连词连接

  从属连词: when, because, although, if, that, which, who, where

• Compound-complex sentence (并列复合句): 两个或多个并列分句，其中至少一个是复合句

Task 2  Choose the right conjunction based on logic

Teacher: Now think about this question. How do you choose the right conjunction? What kind of logic does each conjunction show? Discuss in pairs.

【设计说明】形式总结放第二步之后，学生已经有了足够的例句支撑，归纳水到渠成。连接词的逻辑意义单独拿出来讨论，因为学生往往只记连接词形式不记逻辑关系，写作文的时候乱用连接词。这里必须把常见连接词的逻辑分类讲死：并列/转折/因果/条件/让步。

Step 4  Practice（约12分钟）

Task 1  Fill in the blanks with correct conjunctions

Teacher: Now practice. Complete the following sentences with the correct conjunctions. Six minutes, then we check.

1. Wuhan's universities send out a large number of graduates every year, ______ many of them choose to stay in the city.
