说明文写作英语ppt

⑴ 高中英语说明文的写作应注意哪些

说明文的写抄作应该注意的事项有下面几点:
1.语言简明扼要通俗易懂避免夸张华丽的辞藻要把真实的一面展现在读者面前；
2.说明时一定要把握一个中心主题.说明文中细枝末节较多但不能喧宾夺主；
3.说明的次序非常重要.合理的次序会使文章条理清楚脉络明晰.因此练习时可以尝试不同的次序进行写作找出最合理的一种；
4.由于说明文写实性较强有时难免会让人感到没有生气.因此可以适当使用一些比喻拟人等修辞手段来增加文章的色彩。
英语说明文写作要点：
说明文是阐述事物的特征本质性能结构用途或科学原理的一种文体.其说明的对象可以是具体的如:自然环境仪表设备等;也可以是抽象的如概念定律等。
说明文的写作相对于论说文来说有一定的套路可循因此不是十分复杂.说明科技方面的内容常用定义法比较对比法分类法因果法等;说明自然环境方面的内容常用时间次序法分类法等.当然随着对象的不同具体应该采用的方法也会有所不同。

⑵ 求英文说明文模板

英文说明文模板,从比较对照、分类、特征、因果、人物描写、地点描写、物体描写分别讲解，最后附上常用的句型。
说明文是对事情的发生、发展、结果、特征、性质、状态、功能等进行解释、介绍、阐述的一种文体。这类文章的目的和性质是客观地介绍、解释事物，使读者获得知识和信息，并不需要发表主张、做出证明。一般说来，知识简介，商品介绍，旅游指南，科技读物，工作总结，实验报告，教材辅导等均属说明文之列。
写说明文，可以按时间、空间、结构、逻辑顺序来写，也可以采取举例、比较、对比、分类、分析、说明、叙述等方法。
1.比较对照
比较对照有两种，一是逐点比较，二是整块比较，即AB交错或先A后B：
1）逐点比较：多数人认为这种AB交错的方式可以避免行文的单调沉闷，对比的效果更鲜明突出。如：
There are basic differences between largeand small enterprises. In a small enterprise, you operated mainly throughpersonal contacts. In a large enterprise, you have established “policies” ,“channels” of organization, and fairly strict procere. In the smallenterprise you have immediate effectiveness in a very small area. You can seethe effect of your work and of your decisions ground. In the large organizationyou are normally taught one thing thoroughly. In the small one the danger is ofbecoming a Jack-of-all-trades-but-master-of-none. In the large it is ofbecoming the man who knows more and more about less and less.
2) 整块比较
It is easy to be a winner. A winner canshow his joy publicly. He can laugh and sing and dance and celebrate hisvictory. People love to be with winners. Winners are never lonely. Unlikewinners, losers are the lonely ones of the world. It is difficult to facedefeat with dignity. Losers can not show their disappointment publicly. Theycan not cry or grieve about their defeat. They may suffer privately, but theymust be composed in public. They have nothing to celebrate and no one to sharetheir sadness.
2.分类
分类是人类认识客观世界的重要手段之一，也是描写事物、解释观点最有效的方式之一。通过将一事物分类，可使复杂事物变得清晰明了，便于作者阐述自己的观点。
分类段落的各类排列要条理，可采用从主要到次要，从次要到主要，从多到少或从少到多等方式排列，亦可平行排列。如：
1） As far as political views are concerned, people fall into threecategories. First are the conservative people. Conservatives are opposed tosudden or great changes. Second are the liberal people.These people are infavor of progress and reform. But their opinions often seem to idealistic. Thethird type is the moderate people. The moderates keep everything withinreasonable limits. They are more practical in this hard world. In my opinion,most people seem to belong to this group.
本段采用平行排列的方式，按人的政治观点分为三类：保守、自由和温和。
2) These are several reasons why I decidedtom attend Bingston University . First of all, the tuition is reasonable.Secondly, the university has a deferred payment plan., which lessons the loadof peasant families like mine. Another reason is that Bingston has the finestteachers in its graate program. My chief reason, however, is Bingston’sprogram in agriculture, my chosen field, which is recognized as the leader inthis area.
该段采用主次排列的方式，分析了作者决定上Bingston大学的原因。
3) According to Mr. Li, the fifteenstudents of his cLASS fall into three groups. Seven of them work hard and studywell. They always get good marks in examinations and are often praised by theteachers. Li calls them “good students”. The monitor, the secretary of theYouth League, and the captain of the cLASS volleyball team, are quick infinding out what their fellow students are interested in or what they should doas a collective. They always organize proper activities at the proper time. SoLi calls them “good organizers”. Four other students are very kind to theircLASSmates, always ready to lend them a helping hand. They help to clean thecLASSroom and the corridor even when they are not on ty. Li says that theyare “ good comrades”. “What about yourself?” someone asks him. “I’m a group bymy self ——a good observer”.
该段不同于以上两段，不是先分类再解释，而是先说明其特点，然后定义分类。虽分类并不科学，却达到了其幽默之目的。
3.特征
例证指具体说明人或事物特点、本质及其规律的方法。所用例子需有代表性、典型性。例证型段落的写作方式多为先提出主题再列举事例。在事例之前一般有For example或For instance。例证后面，根据情况还可以加上结论句。如：
In order to prevent non-smokers from beingaffected, measures must be taken to rece the chances of smoking. A lot ofwork can be done concerning this. For example, in some public places, such asin the theatres and cinemas, smoking should be forbidden. Even on the train orplane people should not be allowed to smoke. Doctors, teachers and governmentleaders should take the lead not to smoke. Above all, the harmfulness anddangers caused by smoking should be made known to all through newspapers,broadcast, or TV programs. Also the growing of tobacco and the proction ofcigarettes should not be encouraged. If these measures can be taken, we caneffectively rece the chances of smoking.
4 因果
因果是两个事物之间的关系。一些说明文，议论文通过分析因果关系说明一个中心思想。如不能把因果关系解释清楚，文章将无法说明任何主题。
因果型段落的扩展模式有两种，一是分类编法，另一个是连环编排法。如果只讨论成因或只讨论结果，细节比较简单，只需按其重要性或其逻辑顺序进行编排。分类编排法指先讨论原因，然后讨论结果；或先讨论结果，后讨论原因。
1）分类编排法：
Music is my chief hobby. When I listen tomusic, good things happen to me. If I am lonely or homesick, I listen to popmusic. The quick rhythm, the strong beats of drums lift my sprits. If I amfamiliar with a song, I will sing alone with it and my depression disappears.When I am bored or very tired, I listen to Mozart. His music makes me feelalive. Music also reminds me of home. Before I came to college, my sisters andI would listen to music and sing songs together and cheer us. Now I enjoylistening to music and singing with my roommates because their smiles make meremember the happy times with my family. For me, music is an excellent escape,and without it, I wouldn’t be so happy。
2) 连环编排法是先讨论一组因果，再一组因果，再一组因果，形成一个锁链。当因果紧密相连，前一果为后一果之因时，经常使用这种方式。
Students shouldn’t stay up so late. Becauseof the pressure of examinations, many students burn night candles. The nextday, they have to get enough sleep. As a result, many of them get sleepy inClASs. They couldn’t catch what the teacher says. Not having studied theirlessons well, they find it difficult to make good performance in examinations.So, it is not worthwhile to stay up late if you want to study well.
5.人物描写
人物描写包括外部特征、性格特征、思想状态、行为语言等，用于表现人物精神面貌、披露人物内心活动、揭示人物性格变化，借以突出作品主题思想。如：
My sister is a boyish girl. She has shortand straight hair like a boy’s. She likes white, black and grey colors, as mostboys do. She never cares for shirts, stockings but loves jackets and jeans.Sometimes she wears a men’s suit and leather shores as if she were a gentleman.Basketball and football are her favorite sports. She also enjoys watchingboxing. She always shouts and cheers excitedly when she is watching a footballmatch. When she is with her friends, she always says Ladies first” to othergirls. The most interesting thing is that she has been mistaken for a boy manytimes. And she is pleased with that. She always says that she should be a boy.
第一句作者明确表示他眼中的妹妹是个男孩子气十足的小姑娘。这样读者大都会在心中勾画出一种从长相、穿着到言谈举止都特男孩化的女孩。下文作者正是通过穿着、外貌和性格等方面向读者展现一个活生生的人物形象。
6.地点描写
地点描写指用生动形象的语言对某一地点、某一环境进行具体逼真的描绘，使读者如临其境、如睹其物。地点描写的对象可大可小，在可以为城市、国家，小可是一间教室，一个房间。
地点描写自然按空间顺序排列，作者应立足于一个出发点，由远及近，由近到远，从里到外，从外到里，由左到右，或由右到左进行描写，顺序不可混乱，否则读者会迷失方向。如下面一段作者从大门开始，由外向里逐步介绍学校的布置，读者如同跟着作者参观了一所校园。
Now I will show you around our school. Itis one of the largest middle schools in the city. When you step into the gate,you will see a beautiful flower bed before you. In the middle of the flower bedthere is a fountain with many colored flowers around it. If you walk along theschool road, you will come to the playground, on each side of which are rows oftrees. We often read books under the trees. On the right of the playground aretwo ClASsroom buildings. On the left is the newly-built four-storyed building.I’m lucky to study here. I love my school very much.
7.物体描写
描写物体时应侧重物的形状、规格大小、颜色和功能。任何一段文字都应有叙述的中心，对物的描写也不例外。同样，主题句也应反映出作者对所要描写物体的看法、态度。如：
The first thing I notice in the bride’sroom is the beautiful curtain. This curtain is patchwork in design, and is sewnout of squares of materials of different colors like white, light green, brownand orange. It is made of silk, trimmed with delicate braids. It is about sixfeet long and hangs from a wooden rail. The curtain matches perfectly with thedark wooden rail and furniture in the room.
通过主题句可以看出作者想向读者描写的是一幅漂亮的窗帘。

⑶ 说明文（exposition），描述文（Description），叙述文（narration)的区别

一、主要内容不同。记叙文主要是描写人物和故事情节为主，描述文以写实物，描绘为主，说明文以阐明事理为主。

二、含义不同。

1、Narration即记叙文是以记人、叙事、写景、状物为主，以写人物的经历和事物发展变化为主要内容的一种文体形式。

2、Description即描述文文体基本种类之一。描绘人物、事件、景物的文字。表现手法以描写、叙述为主，同时兼有必要的抒情、议论和说明。

3、exposition即说明文是一种以说明为主要表达方式的文章体裁 。它通过对实体事物科学地解说，对客观事物做出说明或对抽象事理的阐释，使人们对事物的形态、构造、性质、种类、成因、功能、关系或对事理的概念、特点、来源、演变、异同等能有科学的认识，从而获得有关的知识。

三、描写手法不同。记叙文主要以侧面描写烘托，正面描写等，写清故事发生的时间地点人物情节，最后抒发情感。描述文主要以比喻等修辞手法，生动形象描绘出物品的样貌等。

说明文则侧重说理，以简洁科学的语言阐明事理，它通过对实体事物科学地解说，对客观事物做出说明或对抽象事理的阐释，使人们对事物的形态、构造、性质、种类、成因、功能、关系或对事理的概念、特点、来源、演变、异同等能有科学的认识，从而获得有关的知识，揭示深层的意义。
