2022版《优化方案》高中语文人教版必修三学案 第四单元单元写作学案
单元写作学案[同学用书P86]爱的奉献学习谈论中的记叙【题目呈现】(教材84页写作练习)阅读下面的材料，以“牵挂”为话题，写一篇作文。
牵挂是人类从小到老贯穿始终的一种情结。
它是感情的依托，心灵的闪电，精神的升华，是人生七情六欲、喜怒哀乐及生活万象的折射与聚焦。
正由于有了牵挂，人类才有了众多动人心弦的历史，也正由于有了牵挂，生活中才涌现出很多缠绵的故事。
【思路导引】“牵挂”到底是什么？这是一个格外抽象的概念。
在我们身边时刻都存在着牵挂，由于我们每个人都拥有亲情、友情，都会得到父母、伴侣的关怀。
可以说，只要我们生活在社会中，彼此之间就会发生着相关联系，产生牵挂之情。
“牵挂”不仅能反映人与人之间的关系程度，也有助于整个社会的和谐进展。
这个话题涵盖面广，但写作时切口要小，要留意写得巧，写得新，不能泛泛而谈。
本话题写成谈论文为最佳。
文章可接受并列式或正反对比式等结构形式。
【佳作赏析】牵挂是成功的大敌《庄子》里有一个故事：一个下棋能手下棋格外厉害：当他用瓦罐和别人作赌注下棋时，无往不胜；可当他用金银作赌注下棋时就从来没赢过。
为什么呢？庄子说：心有挂碍。
在残酷的战斗中一旦心有牵挂往往意味着失败：虞姬为了不连累项羽最终最终自杀；而项羽对自己的功名耿耿于怀也在乌江自刎。
而我们怎么能想到这个悲剧英雄曾经破釜沉舟、放下一切而以弱胜强，制造了中国军事史上经典的巨鹿之战！而他的敌人刘邦是怎么做的呢？当看到项羽要把自己的父亲绑起来扔下油锅，远远喊话：“不要忘了分我一杯肉羹啊。
”刘邦也是人，可是刘邦忍住了巨大的哀思没有被亲情所牵制，最终成为了汉朝的开国皇帝。
在自然界里，当小狮子长成后，就会被狮群驱除出领地。
很多小狮子饿死了，有的被其他的狮子杀死了。
只有经过大自然无情的优胜劣汰，最强壮的狮子才会活下来，而他们的基因会造就更强壮的后代。
假如狮群牵挂着小狮子的安危，那么最强壮的和最弱小的都获得了生存的机会，这样的种群的衰亡也近在咫尺。

必修3的导学案第4章
第四单元种群和群落第1课时种群的特征[课程重点] 1．种群的特征[课程难点] 1．样方的选择和确定[学习建议]同学们在学习种群的特征时，要将视角从前面的个体水平转移到群体水平，通过实例理解种群的概念，分析个体没有群体才有的种群特征，明确最基本的数量特征是种群密度，其他数量特征与种群密度之间的关系所用的关键词：决定、预测和一定程度上影响等。
[教学建议]（教师书内容）……原书P47的教学建议……第一层级学习目标：知识记忆与理解〖知识体系梳理〗系统形象化一、种群的概念与特征1.概念：在一定的自然区域内，同种生物的全部个体形成种群。
2．种群在单位面积或单位体积中的个体数就是种群密度，它是种群最基本的数量特征。
3．种群的其他数量特征有出生率和死亡率、迁入率和迁出率、年龄组成和性别比例。
二、调查种群密度的方法1．如果要调查……原书P47的知识梳理二（一）3的（1）……2．如果要调查某活动能力强……原书P47的知识梳理二（一）3的（2）……三、种群的其他数量特征（3）应用：利用人工合成的性引诱剂（信息素）诱杀某种害虫的雄性个体，破坏了害虫种群正常的 性别比例，就会使很多雌性个体不能完成交配，从而使该种害虫的种群密度明显降低。
〖课堂预习交流〗知识问题化1．种群的数量特征有哪些？结合种群的特征和个体的特征谈谈如何理解“整体大于部分之和”？答案：种群的数量特征包括种群密度、出生率和死亡率、迁入率和迁出率、年龄组成和性别比例。
种群会出现个体所不具备的特征，所以说“整体大于部分之和”。
2．用样方法调查植物的种群密度时，求得每个样方的种群密度后，如何计算该种群的种群密度的估计值?答案：以所有样方种群密度的平均值作为该种群的种群密度的估计值。
3．在对某种鼠的调查中，调查范围为1公顷，第一次捕获并标记39只鼠，第二次捕获34只，其中有标记的鼠15只，请运用数学方法估算这个种群的种群密度（单位为只/公顷）？ 答案：设每公顷的鼠为N 只，依据公式341539 N ，解得N=88（只/公顷）。

语文必修三第四单元导学案【学习方针】知识方针：了解相关文体、字词能力方针：培养删选信息的能力感情方针：培养对科学的兴趣与热爱一、文体知识1、【说明文的概念】说明文是以说明为主要表达方式来解说事物、阐明事理而给人知识的文章体裁。
它通过揭示概念来说明事物特征、本质及其规律性。
说明文一般介绍事物的形状、构造、类别、关系、功能，解释事物的原理、含义、特点、演变等。
说明文实用性很强，它包孕广告、仿单、概要、提示、轨则、章程、解说词、科学小品等。
【说明文的语言特点】准确、简洁、平实是说明文语言的主要特点。
当然，说明文的语言风格也是多种多样、各有特色的，有的以平实见长，有的以生动活泼见长。
以此为据，可概括为平实说明和生动说明两种方式。
一般来说，以说明事物为主的说明文，重在抓住事物的特点，用简明的语言平实地加以说明。
而科学小品，讲究趣味性、文艺性，必要作必要的生动、形象的说明。
【说明方式】①举例子。
使文章更加具体，更有说服力，更客观地说明了事物。
使比力抽象，复杂的事情或事物变得通俗易懂，让人信服。
举例子必需让人感觉有真实感。
②.打比方。
说明某些抽象的或者是人们比力陌生的事物，可以用具体的或者大师已经熟悉的事物和它比力，使读者通过比力获得具体而鲜明的印象。
增强说明的形象性和生动性的说明方式叫做打比方。
说明文中的打比方，同修辞方式中的比方是一致的。
用这个方式，可以把抽象复杂的事物说得浅显易懂，具体生动。
分歧的是，比方修辞有明喻、暗喻、和借喻，而说明多用明喻和暗喻，借喻则不宜使用。
（把……比作……，体现了……的……特点……）③下定义。
用简明的语言对某一概念的本质特征作规定性的说明叫下定义。
从而更科学、更本质、更概括地揭示事物的特征/事理。
下定义能准确揭示事物的本质，是科技说明文常用的方式。
④列图表。
为了把复杂的事物说清楚，还可以采用图表法，来弥补单用文字表达的缺欠，对有些事物解说更直接、更具体。
使读者直观，一目了然地了解事物的特征。
