Writing Section Ⅴ 写作项目——Write about a healthy diet 课时跟踪检测 Contents 目录 01 02 2 01 写作项目——Write about a healthy diet 本单元的写作任务是写一篇关于健康饮食的文章，属于科普说明文的范畴。写作时注意保持客观中立，语言简洁清晰，信息准确可信，逻辑严密连贯，并适当运用举例等写作手法，以有效地向读者传达观点和信息。 |由课文学写作| 一、学写作架构 阅读课文，总结本课的篇章结构如下： 二、学要点构思 说明文一般结构清晰，常采用“总—分—总”的行文结构。本文作者首先提出了关于健康饮食的争议，指出健康的大敌不是脂肪而是糖，并通过引用研究数据来支持这一观点。然后详细介绍了如何保持健康的饮食习惯。最后，文章总结了健康饮食的关键是要有正确的饮食态度，并强调个人应该决定自己想要的生活方式并做出正确的饮食决策。 三、学语言风格 此类说明文通常采用客观、中立的语调，避免夸张或主观评价，以提供客观、准确的信息。语言简洁明了，表达直截了当，避免冗长的修辞。如课文第二段中“Much of this extra sugar comes from sweets and sweet drinks.” 直接说明了多余的糖分主要来自甜食和甜饮料。“The average American gets 1/3 of his or her sugar through sweet drinks alone.”用简单的语言清晰地说明了美国人摄入的糖分平均有三分之一来自甜饮料。 四、学写作手法 文章通过对比、下定义、举例子等写作手法，清晰地阐述了作者对于健康饮食的观点和建议，使读者更容易理解和接受这些观点。 1．对比法：课文第一段中 “scientists have insisted for years that a big enemy of health is fatty food. However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar.”通过对比指出科学家长期以来对于健康的认知与现有证据之间的矛盾，突出了作者的观点。 2．下定义：课文第三段中作者给出了加工食品的定义，即加工食品指营养成分较低，而糖分、盐分和脂肪含量较高的食品，这种定义性的表述使读者更容易理解作者的观点。 3．举例法：作者使用具体的例子来支持论点，增加了说服力。如课文第二段中“The American Heart Association recommends that we limit ourselves to less than 100－150 calories a day from sugar, which is less than what is usually contained in one can of sweet drink or in a single candy bar.” 通过举例说明了每日需要摄入的糖分，强调了甜饮料和糖果的高糖含量。 |写作项目指导| Write an explanatory article about healthy eating　——写一篇关于健康饮食的科普说明文 第一步：构思谋篇 体裁 说明文 时态 以现在时为主 人称 以第三人称为主 写作要点 1.开头：引入文章的主题，概括性地介绍要说明的内容，以吸引读者的注意力。 2.主体：展开说明主题的各方面，可以按照时间、空间、因果关系等逻辑顺序进行组织。 3.结尾：总结文章的主要内容，强调自己的观点或提出建议。 第二步：要点表达 第一部分：点明主题，表明健康饮食的重要性 _________________, healthy eating habits are _________________ ____________because a good eating habit ________________________ ___________________in our daily life. 众所周知，健康的饮食习惯与我们的健康息息相关，因为良好的饮食习惯提供了营养，使我们在日常生活中精力充沛。 As is known to all in association with our health provides the nutrition that makes us energetic 第二部分：健康饮食的建议 1．________________, “We are what we eat.” Therefore, _____________________fresh fruit and vegetables every day, as they are rich in vitamin and fibre.俗话说，“人如其食。”因此，每天吃新鲜的水果和蔬菜很重要，因为它们富含维生素和纤维。 As the saying goes it is important to eat 2．Besides, _________________________desserts and cut out sweet drinks,_____________________________________________.Last but not least, it _______________________________you should keep away from junk food.此外，最好少吃甜点和禁止甜饮料，因为它们会导致体重问题和心脏病。最后但同样重要的是，强烈建议你远离垃圾食品。 it is better to cut down on which can cause weight problems and heart disease is strongly recommended that 第三部分：总结 To sum up,____________________________________.

I immediately hid it under my seat, hoping no one would take notice. Mom had really outdone herself with masala — our family's all-time favorite dish back in India. But today, it wasn't just about me and my lunch. A warm smile on his face, Ricky invited me, a new transfer student from India to New York City, for lunch. “Ava, come sit here！” Ricky called out, gesturing towards a vacant seat. As I made my way over, memories of those awkward lunchtimes when I studied in Kansas, one of the most conservative states, flooded back. I could still recall how everyone would wrinkle their noses and stare curiously when I unpacked my Indian food. It always made me feel like an outsider, as if I didn't belong. Therefore, before my first day in this school, I had demanded my mom pack “normal” Western-style food for me. I still remembered the look on her face upon hearing it, as she signed in disappointment and confusion, “Isn't there a moment when you feel proud of your origin？” That was hurting, but not more hurting than others' giggles and whispers. Honestly, long queues were common in Indian restaurants in New York City, a cultural melting pot, but I wouldn't take that risk. Unfortunately, this morning, Mom had forgotten to make sandwich or any “normal” food, so I had to bring leftovers from our dinner. At the thought of making a fool of myself in public, I felt like being thrown into darkness. However, before I came back to reality, Ricky noticed my sneaking (躲躲藏藏). “What do you have for lunch？” he asked, his eyes twinkling with interest. I tried to brush it off (搪塞), claiming I wasn't hungry. But Ricky wouldn't let it go, and before I could protest, he had the lid of my lunchbox open and I prepared myself for such a familiar response “What is that？” 注意：1.续写词数应为150左右； 2．请按如下格式作答。 However, I did not get what I was expecting.　   　 After school, I found Mom preparing sandwich for tomorrow's lunch.　 参考范文： However, I did not get what I was expecting. Ricky took a deep breath, closed his eyes, and tasted the masala. Instead of the usual stares and whispers, there was only interest on Ricky's face. His face lit up with a broad smile, asking, “Your mom made masala for your lunch？” Before I could make a response, he added, “I could be dying of envy! You know that, last Sunday, my parents and I queued up for three hours in terrible cold in Fifth Avenue for the new Indian restaurant.” He enjoyed every bite, nodding his head in approval. It was a welcome change from the stares and whispers I had grown accustomed to. After school, I found Mom preparing sandwich for tomorrow's lunch. I came over and asked if I could have Indian food in my lunchbox, which made her a bit confused. Finally, I told her about my experience with Ricky and how he had enjoyed my food. Mom's face lit up with joy. “I'm glad he liked it，” she said. “And I'm even happier you're starting to feel proud of your roots again.”She paused and looked at me seriously, “Your culture, your traditions, and your food are all a part of who you are.” I nodded, feeling a sense of relief wash over me. Mom's words had given me the courage to embrace my identity and share my culture with others. 二、阅读拓展训练 “Farm to table” is the name of a movement that encourages people to eat locally grown food. The farm-to-table idea has become more popular in recent years. But there is also a movement that brings “table to farm”. Its purpose is to connect people to the land and to honor local farmers by creating a sort of restaurant without walls. Its founder, Jim Denevan, got the idea for this kind of “culinary adventure (美食探险)”， as he called it, ten years ago. He recently prepared tables for more than a hundred people at Briars Farm in Virginia. He and his eight-member team arrived the night before. Chefs from a local restaurant prepared the dinner. Jim Denevan's brother is a farmer and he himself is a chef. He thought that the idea of a meal served right on the farm made sense, though not everyone agreed. “But I wanted to make the idea work, so I decided to cross the country, ” said Denevan. “I went all the way across the United States and set the table on farms, ranches (大牧场) and beaches, and all the places where food came from.” “This kind of event connects us with a lot of enthusiastic people, people that we can form relationships with，” said Matt Szechenyi, who operates Briars Farm. The tour of the farm ends at the dinner table. The meats in the meal come from Matt Szechenyi's farm. The vegetables come from nearby farms. Guests and local farmers sit together. Annoica Ingram came with a friend. “The food is wonderful. I appreciate their hard work. I see everything they have to do to take care of the animals and make sure they are well-cared-for. Without them, I think, we'll have big problems，” she said. √ 语篇解读：本文为一篇新闻报道。文章介绍了“从餐桌到农场”的活动。该活动将餐桌搬到农场里，建立了人与人之间的交流，食材和食材之间的流通。 1．What is the main purpose of the movement “table to farm”？ A．To provide people with healthy food.

A．make new friends B．walk around the farms C．communicate with farmers D．build restaurants for farmers √ 解析：推理判断题。根据最后一段中的“I appreciate their hard work ...

A．worried　　　　　 B．grateful C．doubtful D．supportive √ 解析：推理判断题。通读全文可知，文章开头介绍了该项活动的由来及目的，第二、三段介绍了该活动创始人的相关内容，最后一段引用了活动参与者的看法，符合新闻写作的结构及格式。故选B。 4．What kind of writing is the text likely to be?
