高中英语校本课程话题写作 Topic5 Expository writing教案1

Respected audienceToday we gather together to explore an eternal and profound topic: self-love. In this busy and challenging world, we often overlook one of the most important things: building a good relationship with ourselves. Therefore, I would like to share some insights on the importance of self-love for mental health.Firstly, let us understand that self-love is not a selfish act but a necessary self-care. Just like the safety instructions we hear on an airplane, we need to put on our own oxygen masks before assisting others. Similarly, only when we are filled with love and care for ourselves, can we better take care of others and cope with life's challenges.Secondly, self-love is the cornerstone of building healthy self-esteem and confidence. When we have respect and recognition for ourselves, our inner strength grows stronger, allowing us to better face external judgments and pressures. This confidence and self-esteem also influence our relationships with others, making it easier for us to establish positive interactions and collaborations.Furthermore, loving ourselves means accepting our imperfections and striving to become a better version of ourselves. Nobody is perfect, but we can achieve personal growth and progress by accepting our flaws and mistakes, and striving for improvement. This positive attitude not only helps us enhance our abilities and performance, but also strengthens our positive attitude and sense of happiness towards life.Lastly, let us remember that self-love is a continuous process that requires constant time and effort from us. By caring for our physical health, emotional needs, and spiritual growth, we can build a stable and healthy self, laying a solid foundation for a more fulfilling and meaningful life.Before concluding my speech, I would like to invite everyone to think together: how can we better express love and care for ourselves in our daily lives? Let us work together to create a world filled with more love and understanding.Thank you all!译文：以爱自己为主题的心理健康讨论发言稿尊敬的各位听众，今天我们聚集在一起，探讨一个永恒而又深刻的话题：爱自己。

Expository writing is a type of writing, the purpose of which is to inform, explain, describe, or define the author's subject to the reader.Expository text is meant to deposit information and is the most frequently used type of writing by students in colleges and universities. A well-written exposition remains focused on its topic and lists events in chronological order. Examples of this type of writing are cooking instructions, driving directions and instructions on performing a task. Key words such as first, after, next, then and last usually signal sequential writing.Second-person pronouns may be used in such writing, if needed; for example, in a how-to essay a writer may choose to personalize the instructions with "you." However, the use of first-person pronouns should be avoided. Expository essays will not reveal the opinion of the writer.Expository writing appears in and is not limited to letters, newsletters, definitions, instructions, guidebooks, catalogues, newspaper articles, magazine articles, manuals, pamphlets, reports and research papers.The general characteristics of expository writing include:∙focus on main topic∙logical supporting facts∙details, explanations, and examples∙strong organization∙clarity∙unity and coherence∙logical order∙smooth transitionsWisdom is knowledge of what is true or right coupled with just judgment as to action; sagacity(精明), discernment（洞察力）, or insight. It is an ideal that has been celebrated since antiquity as the application of knowledge needed to live a good life. Beyond simply knowing/understanding what options are available, "Wisdom" provides the ability to differentiate between them and choose the one that is best.What this means exactly depends on the various wisdom schools and traditions claiming to help foster it.

The ability to critically examine and challenge established ideas can set a student's writing apart and demonstrate their intellectual prowess.Finally, the process of revising and editing one's work is crucial in the realm of application-oriented English writing.

除了一般课堂作文外，多用于研究报告及实验结果的文章。

说明可分为两种：（I）事物说明文：指说明的事物是具有形体的东西。

（II）事理说明文：指说明抽象的概念，或介绍事物的本质属性，或陈述事情的原因等。

说明文与其他文体的分别：（I）说明与记叙：说明偏重于知识性、科学性，大多是为了解释说明某些客观事物，帮助读者了解客观世界；叙述则偏重于具体地反映事物的情况和变化过程，使人有所感知和感动。

（II）说明与描写：说明要求以平实简洁的语言，将事物的状态、性质、功能、成因、过程等告诉读者；描写是对事物作生动的描绘，使读者有深刻的感受。

（III）说明与议论：说明是为了让读者了解情况、明白事理、知道真伪，一般不确立什么论点；议论是对事物或问题进行推断、论证、发表评论、提出作者的论点及主张。

说明的方法：（I）定义说明法：对某种事物的本质特徵或概念作准确而简要的说明。

（i）简短定义Short Definition：先陈述要解释的定义，再说明它所属的组别，最后说明它与其他组别不同之处。

“Pardon” is an action of a court or ruler forgiving a person for an illegal act and giving freedom from punishment.“Excuse”is the reason, whether true or untrue, given when asking to be forgiven for absence, wrong behavior, a fault, etc.( Longman Dictionary of Contemporary English )（ii）延伸定义Extended Definition：有别于简短定义只用一两句来解释，延伸定义本身便可成一篇文章，而通常要下定义的语句较为复杂或抽象，而解释的方法包括：（1）提供例子说明；（2）列出其显着的特点和特徵；（3）提出历史发展的实证；（4）以比较及对比方式来解释；（5）先分明别类，再逐一说明每类之差异；Example:One-upmanshipOne-upmanship is the art of impressing other people. You are “one up” on someone if you have said something impressive, something that makes the other person feel inferior. At the beginning of this year, I met three new students who all knew the art of one-upmanship. One said that his brother was a lieutenant in the Marine Corps. The other told me that he had been at a school that had its own fully equipped television studio. The third had just come from an exclusive prep school in New England. To play the game, I should have thought of an answer that would put me “one up” in turn. To the first, I should have replied that my uncle is the adjutant to the Commanding General of the Corps. To the second, I should have said that our school has an electronically operated language lab. To the third, I should have said that my father is a professor at Harvard. Unfortunately, none of those things is true.分析如下：本文向读者说明一个单词－One-upmanship，并运用了简短定义法，对One-upmanship 下了扼要定义，跟着以举例方法延伸这词的解释，用作者见到的three new students 如何运用one-upmanship的例子来说明，以及他欲反败为胜的方法，将抽象的定义演绎成具体生动的事例。
