如何学习数学作文【一】

说明文是以说明为主要表达方式用来说明事物,阐明事理的`一种文体。它通过揭示概念来说明事物的特征、本质及其规律性,给人准确的科学知识或正确思想。一般可分为实体事物说明和抽象事物说明两大类,词典、教材、论文、实验报告、产品说明书、广告、解说词及科学小品等都属于说明文。

按写作方法,英语说明文主要分为下面六种类型

1.例证法 2.定义法 3.分类法 4.因果关系法 5.比较对照法 6.过程分析法

1.例证法

Our life today depends very much on energy. For example, machines have made our life easier than it used to be. The machines use energy, and energy is needed for heating, lighting, communications, carrying goods-everything. Factories use a great deal of energy to make the things that we use and buy and sell.

这段主要是讲能源问题。第一句为主题句,概括地说出"我们目前的生活很大程度上依赖能源"。接着用举例的方法从三方面说明能源的作用。

2.定义法

An ideal teacher must have the following characteristics. He should know his subject, but he can make mistakes if he is willing to learn. His personality is as important as his scholarship. An ideal teacher must be enthusiastic. He should be a bit of an actor and he shouldn't be afraid to show his feelings and express his likes and dislikes. An ideal teacher is one who grows, learns, and improves himself along with his students.

本段的展开是通过对"一个模范教师"下定义的方法,关键词"ideal teacher"在文中多次重复,能加深读者的印象。

3.分类法

As far as political views are concerned, people fall into three categories. First are the conservative people. Conservatives are opposed to sudden or great changes. Second are the liberal people. These people are in favour of progress and reform. But their opinions often seem too idealistic. Third are the moderate people. The moderates keep everything within reasonable limits. They are more practical in this hard world. In my opinion, most people seem to belong to this group.

本段把人按政治观点分为三类:保守派(conservative people、自由派(liberal people和温和派(moderate people,并对他们各自的特征进行了简要的分析。

4.因果关系法

Of the four seasons, I like spring best. I prefer spring because it is a season of much joy and gaiety. New life bursts out everywhere. Plants wear a green coat again and colourful flowers blossom in gardens and mountains. The old come outdoors for fresh air and the young plan for outdoor activities. Life becomes so energetic and happy.

第一句为本段主题句,末句是总结句。在主题句后, 作者用了四个句子阐述自己喜欢春天的理由。

5.比较对照法

I like having a twin sister. When she's happy, I'm happy. When she feels unhappy, I feel the same. Often, I know what she's going to say. Sometimes, I know what she's thinking. I like what she likes. I hate what she hates. We like the same music, the same food and the same books.

这段采用AB交错的比较方式,阐述孪生姐妹的相同特征。这种写法较流畅自然,给读者的印象也更鲜明突出。

6.过程分析法

There are several steps to plant a tree. First, dig a hole large enough for the tree, but the hole should not be too deep. Second, put the tree in the hole so that it is straight. Third, put the earth back into the hole again. Push it down hard with your foot several times. Finally, water the tree well, as often as possible.

这段分析了植树过程中的几个步骤。全段层次分明,连接词语(first, second, third, finally的使用加强了语句的连贯性。

Unfortunately, nowadays in many parts of the world lots of people fail to realize the importance of trees. They have cut trees down in large numbers without a plan, which makes the soil washed away. They don’t know where there are no trees, the rain washes away the surface of the soil and this causes floods.

电脑

五年级 陈丽媛

提起电脑,相信大家都非常熟悉。电脑又叫电子计算机。如今,随着科技的发展,电脑已走进千家万户。

电脑一般分为两大类;一类是个人电脑,个人电脑有台式的,笔记本的,最新式的是平板的。另一类是超级电脑,每秒的运算速度在亿次以上,主要用在银行、科研、军事等方面。

电脑由硬件系统和软件系统组成。电脑的硬件系统主要由主机、显示器、键盘、鼠标、音箱、摄像头等组成。主机就是电脑的主管,就像我们的头脑,控制着电脑每天的工作。显示器就像我们的眼睛,把所有工作的成果展示给我们看。键盘上有26个英文字母键,方向键,数字键和几个重要按键,是电脑主要的输入设备。鼠标就像一只老鼠似的扒在桌子上,可是作用非常大,可以灵活地指挥各种应用程序。音箱可以带领我们进入美妙的音乐世界。摄像头可以让我们足不出户,与世界各地的人们交流。电脑的软件系统分为两类;一类是操作系统软件,主要有windows操作系统和Linux操作系统等,最原始的是dos操作系统。它们是计算机底层的系统软件,负责管理、调度、指挥计算机的软硬件资源使其协调工作,没有它,任何计算机都无法正常运行。它在资源使用者和资源之间充当中间人的角色,举个例子,一个用户(也可以是程序)将一个文件存盘,操作系统就会开始工作:管理磁盘空间的分配,将要保存的信息由内存写到磁盘等。当用户要运行一个程序时,操作系统必须先将程序载入内存,当程序执行时,操作系统会让程序使用CPU。另一类是应用软件,可以办公,也可以游戏,还能保证安全等等。

电脑的用途很多:可以上网,例如聊天、发邮件、听音乐,玩游戏、登Q、查资料等;可以管理资料,比如学校的图书室里的电脑是用来登记图书借出去情况的;可以记帐,比如超市里的计算机,就是拿来记帐的;还可以控制生产,比如水泥厂里的电脑能自动控制生产。瞧,电脑真是各方面的能人!

电脑与人们的生活息息相关,让人们的生活变得更美好。

为促进家庭和学校合作,让家长和老师共同激发学生学习潜能,索河西街小学应教体局的要求积极组织家长、学生和老师观看《如何激发孩子学习潜能》主题视频节目。

学校副校长王亚辉要求班主任把教体局的观看通知发给家长,各位班主任开会后纷份通过校讯通和微信群发消息给家长,周六早上有些班主任又提前十分钟把通过网络搜索收看的方法告知了家长,在老师的积极组织下,2月25日7点52分大部分的家长和学生准时收看了人大附中王金战老师的《如何激发学生学习潜能》主题教育节目。

周一到校后,四二班的两三名学生高兴地围着老师说:看了节目,我和妈妈找到了提高学习的方法,那就是一次订个小目标,一次提升两名,慢慢就会越来越棒!还有部分家长写了观后感,一位家长写道:观看了王老师的讲座后,我知道了如何激发孩子学习潜能,不能打击孩子,以前我总是要求孩子考100分,这是不对的,以后我要多鼓励孩子,让他一点一点的进步。

相信此次观看《如何激发孩子的学习潜能》教育节目,定能使广大家长和老师学到有效的教育方式,改变以往急功近利的教育观念,在以后的教育中多鼓励,多表扬,激发出学生的学习潜能,学生和家长、老师也定能不断的共同成长。

如何学习数学作文【四】

多年以来,经常有学生的家长问我:刘老师,当年在您的中学时代,成绩那么好,您在学习上有什么秘密没有?怎样才能让我的孩子成为最顶尖的学生?考上最顶尖的大学呢?

听到这个提问的瞬间,我往往本能地一脸茫然,一时间不知如何作答。待到醒过神来,我的思绪往往会想起学生时代看过的一本漫画书《七龙珠》。

其中有一段的故事是说两个小孩子,小悟空和克林,向著名的武道家龟仙人学习武术的经历。龟仙人是闻名世界的第一武术大师,他训练出来的徒弟无不是天下无敌的一等高手。小悟空和克林两个都觉得,龟仙人一定有着一套绝密的训练方法,和出神入化的拳法,所以不远万里来到龟仙人居住的海岛前来。经过一番严格的考察之后,龟仙人答应收下他们两个为徒,并开始了严格的训练……

然而出乎他们二人意料的是,龟仙人武术训练的第一步居然是清晨让他俩去挨家挨户送牛奶,只不过是要每个人端着沉重的牛奶箱子,跋山涉水跑上十几里路去送。早餐后要帮农民伯伯耕地,但是不能用锄头,要用自己的两个手掌……一个上午下来,十根指头疼痛不已;下午要去建筑工地干活,傍晚在大湖里往返游上十个来回,当然,要拼命游,因为湖里有大鲨鱼……几天下来,徒弟问龟仙人什么时候教他们拳法。龟仙人指着旁边一座小山一样的巨石说:你们什么时候推动这块大石头,我就教你们拳法,从明天开始,就重复每天的体力训练,但是要背着20公斤的龟壳。

几个月不知不觉的过去了,他们还是每天重复着这样的基本体能训练,但是身上的龟壳加重到了40公斤,训练还在继续……

突然有一天,小悟空兴奋的叫龟仙人爷爷出去,他居然可以把那座山一样高的巨石推开了,一时间惊讶得龟仙人目瞪口呆,心说自己当玩笑说的一句话没想到这个小鬼还当真了。克林惊讶之余也去试了试,发现也推动了那块巨石。两个孩子兴奋地要龟仙人教他们拳法。

龟仙人这时候摇摇头说:我已经没什么可以教你们的了,龟仙流的基本武术已经完全包含在这几个月的训练里了,也许你们自己都没觉察到,但是你们的眼力,拳脚,所有身体部位的力量和反应速度都已经锻炼到了超越常人的\'地步,所谓的拳法,只不过是将这些活学活用而已,没有这些基本功,什么拳法都不过是些花拳绣腿。你们可以摘掉40公斤的龟壳往起跳一下试试。

两个孩子摘掉龟壳,纵身一跃就直入云端,简直如小鸟一般轻盈,挥拳下去,就是石破天惊一般。在随后举行的天下第一武道大会里,一路夺关斩将,击败世界上各路武林高手,轻松***入了最后的决赛。

作为漫画,这个故事虽然夸张但绝不荒诞。回想起我本人的学生时代,尤其初中,既没有辅导班也没有太多的参考书,遇到一本辅导书,习题集就跟宝贝一样从头到尾仔仔细细看一遍做一遍。至于教材,那更是几乎翻烂了不知反复阅读思考了多少遍。没有人给我讲什么难题,也没有什么名师指点,我具备的功力不外乎基础知识掌握的非常扎实,基本技能强化的非常到位。尤其是后者,基本技能的强化,正所谓熟能生巧,巧能生精。就这样,以592分的高分考进了北京四中。正如龟仙人所说的那样,基本功到位了,所谓的拳法不过是活学活用而已,学习也是一样,基本功扎实了,思路自然就有了,难题不用老师讲,自己也能逐步拆招换式的把它自主攻克。

现在同学们有了《乐学100在线课程》这样一个好老师,要达到同样的学习高度,你们已经比我上学的时候轻松了不知道多少倍。这套系统已经把所有基础知识,尤其是需要强化的基本技能都帮助同学们整理出来了,你们只需要按照课程的要求依次完成即可。刘老师我中学的时候,就好比自己拿着土制的石锁和磨盘来练身体,你们则好比在现代化的健身房里有优秀的教练指导来练。但无论什么条件,你不练都是没有任何结果的。

这时候,我也明白了为什么每当家长问我开篇那个问题的瞬间我会一时间不知道如何作答,还记得电影《功夫熊猫》里众人舍命争夺的至尊武林秘籍是什么吗?那就是:没有秘密。
