Task 3 - Reading for the language: Underline the linking words in the passage that introduce another way of saying what was already mentioned in the previous sentence. 【参考答案】 put more simply, in other words, what this means is that Circle the linking words in the passage which show that conntrasting ideas are being introduced. 【参考答案】 however rather than rather(相反) 连接词小结（Linking Words Summary） Addition（补充）: moreover, in addition, besides, furthermore Contrast（对比）: however, on the other hand, nevertheless, instead, rather than Explanation（解释）: in other words, that is to say, put simply Cause & Effect（因果）: therefore, as a result, thus, so Tips: 衔接词语(linking words)是语篇衔接的纽带, 表达的逻辑意义包括时间关系、空间关系、列举和顺序、例证、递进、对比和转折、等同和替换、过渡和总结、结果和推论等, 其中多数是衔接性状语。 应用实践 Writing paractice Task 1语言分析 选取文章中的重点段落，分析其中的句式结构、词汇运用和连接词的作用。 【教师参考】 "A balanced diet means choosing a variety of foods from each of the five food groups: grains, vegetables, fruits, dairy products, and protein sources. This ensures that your body gets all the nutrients it needs." Step 1: 句式结构 (Sentence Structure) 教师提问： "Let's look at the first sentence. What is the subject? What is the verb? What does 'mean' do in this sentence?" 引导学生发现： 主语 (Subject): A balanced diet 谓语动词 (Verb): means 宾语 (Object): choosing a variety of foods... (这是一个动名词短语作宾语，说明“均衡饮食”的具体内容是“选择各种食物”) 冒号 (:) 后面的内容是对 the five food groups 的举例说明。 Step 2: 词汇运用 (Vocabulary Use) 教师提问： "Why does the author use 'means' instead of 'is'? What's the difference between 'choose' and 'choosing' here? What does 'ensures' tell us?" 引导学生分析： means: 意为“意味着”，比 is（是）更强调定义和内涵，说明“均衡饮食”是一个动态的“选择”过程。 choosing: 动名词。跟在 means 后面，将动词“选择”名词化，作为means的宾语，使表达更紧凑。 ensures: 意为“确保、保证”，是一个非常肯定的强势动词。它清晰地表达了“多样化选择”和“获取全部营养”之间的必然因果关系，比 makes 或 lets 更有力。 Step 3: 连接词与指代 (Linking Words & Reference) 教师提问： "What does the word 'This' at the beginning of the second sentence refer to? What is the function of this word?" 引导学生分析： This 指代前一句的整个概念——choosing a variety of foods from all five groups。 作用： 避免重复，使两句话之间的逻辑衔接非常紧密。前一句提出做法，后一句立即阐明这种做法的直接好处，文章流畅自然。 【教师参考】 主语 (Subject): A balanced diet 谓语动词 (Verb): means 宾语 (Object): choosing a variety of foods... (这是一个动名词短语作宾语，说明“均衡饮食”的具体内容是“选择各种食物”) This 指代前一句的整个概念——choosing a variety of foods from all five groups Task 2 小组讨论 “What are the common unhealthy eating habits in our daily life and how can we change them?” 【教师参考】 教师提供语言支架 (Language Support): 将以下句型写在黑板上，帮助学生进行讨论 指出问题 (Identifying problems): “One common bad habit is... / Many people often...” “For example, some students... because...” 提出建议 (Giving suggestions): “To solve this, we should... / A better way is to...” “We can change this by...ing / It is better to... rather than...” “As the text suggests, we need to...” Task 3 写作框架 开头段 (Introduction) 主体段 (Body Paragraphs) 结尾段 (Conclusion) 【教师参考】 开头段 (Introduction): 引出话题 + 阐述重要性。 引导问题： “How can we start? How can we grab the reader’s attention?” 搭建框架： Hook: 普遍现象/问题开头 (e.g., “Nowadays, many people have some unhealthy eating habits.”) Topic: 点明主题 (e.g., “So, it's very important for us to know what healthy eating is.”) Thesis: 亮出观点 (e.g., “A healthy diet means...”) 主体段 (Body Paragraphs):分点论述建议 + 举例说明。 引导问题： “What are the most important suggestions from the text and our discussion? How can we support them?” 搭建框架: Topic Sentence: 提出第一个建议。(e.g., “First, we should eat a variety of foods.”) Explanation: 简单解释原因。(e.g., “This ensures we get enough nutrients.”) Example: 举出个人例子。(e.g., “For example, I will try to have an apple and some milk...”) Transition: 使用连接词，转入下一点。(e.g., “Besides, it’s also crucial to...”) 结尾段 (Conclusion):总结全文 + 提出呼吁。 引导问题： “How can we end the passage? What final message do we want to give?” 搭建框架： Restate Thesis: 用不同的话重申观点。(e.g., “In short, healthy eating is not about strict rules but about making better choices.”) Call to Action: 提出呼吁。(e.g., “Let’s start to pay attention to what we eat and develop healthy habits from now on!”) 【自我评价】 项目 掌握情况（✔/△/✖） 我能理解文中关于健康饮食的主要观点和建议。 我学会并运用了与健康饮食相关的新词汇。 我能辨别文中的健康饮食误区，并有自己的思考。 我能结合课文内容，制定一份个人的健康饮食计划。 我认识到健康饮食是一种重要的文化理念。 迁移创新 作业内容 本节课作业二选一，为分层作业，难度有所区别。基础一般的同学可以选择作业一，基础较好的同学可以选择作业二。 （一）基础作业 Part A: 1.Many people believe that skipping breakfast is a good way to lose weight. __________ (然而), this is a common myth; __________ (事实上), it may lead to overeating later in the day. 2.Eating a variety of foods is crucial. __________ (例如), you can try having some fruits for breakfast __________ (而不是) always eating bread. 3.He didn't listen to his body's signals and often ate too much. __________ (结果), he often felt tired and uncomfortable after meals. 【答案】 1.However, / in fact 2.For instance, / rather than 3.As a result Part B: 4.________________________________________ (重要的是要有一个均衡的饮食) which includes carbohydrates, proteins, and fats. 5.________________________________________ (不要只关注卡路里); you should also consider the nutritional value of the food. 6.________________________________________ (关键是要适度地吃) and enjoy your food without feeling guilty. 【答案】 4.

A balanced diet is essential for our growth, study, and daily life. However, some of us have unhealthy eating habits, such as skipping breakfast, eating too many snacks, being picky about food, or overeating. These habits may lead to lack of energy, poor concentration, and even health problems. To improve our diet, I suggest we take the following steps:First, eat three regular meals a day, especially breakfast. Second, choose more fruits and vegetables instead of junk food. Third, drink plenty of water and avoid sugary drinks. Let’s develop good eating habits together. Remember, we are what we eat. Thank you! ( 7 / 8 ) 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
