How To Be A Happy Kid

Good morning, dear judges!

My name is Joyce. Today I will give a speech about How To Be A Happy Kid.

Everyone deserves to have a happy childhood. We all know, life isn’t

easy all the time, even for children.

One time I didn’t do well on a math test. It was the first time for me

to get such a low mark. I felt miserable about it. When I got home, without

saying a single word to my parents, I rushed into my own room. I sat down

in front of my piano. Unconsciously, music came out from my fingers. I was

lost in the beauty of the music. My heart flew with the song in the air. The

piano music was just like a wise old man consoling me with soft words. After

playing the music, I felt very calm and happy.

We shouldn’t lack for joy in life. The key is to find ways

to be happy. For me, playing the piano helps me初中物理 find the road back to

happiness. For other children, they might find it other ways, like by

singing, dancing, playing soccer or helping people. But for all of

us, it should come from knowing our parents love us.

I am a child. Children shouldn’t worry about anything. I wish every

kid is a happy kid.

Thank you for listening!

全文共 1109 字

初中英语写作教学要把握一定的基本策略。写作是一个角度复杂的思维过程,对认知能力、思维能力、语言能力、组织能力和自我监控能力都有相当高的要求。写作水平的提高依赖于学生的参与,依赖于教师的指导和课堂教学的有效开展。

所谓写作教学策略,就是用来促进写作教学开展的方式方法。

1.写作的早期训练。英语写作是一门技巧、技能,需要一个长时间的发展过程才能趋于稳固,因此无论从写作能力本身的培养角度来说,还是从写作教学方法的运用角度而言,写作训练都需要早期化。

2.随着学习内容的增多,如学了数字、年龄、年级、班级、个人的喜好和生活习惯等之后,这时可让学生逐步增加写作内容。

做好“书面表达”这道题,学生应该从以下几方面人手:

一、充分准备。打好基础。

为了提高书面表达水平,平时应加强阅读,应背诵一些句型、段落甚至短文。只要读得多、背得多,就能出口成章,下笔成文。其实,用英文写信,记日记等都是学生力所能及且行之有效的练习写作的好方法。

二、仔细审题,明确要求。

对题目所提供的信息要认真分析,明确要求,做到心中有数。要对所提供的信息加以分析、整理,使之更加具体化、条理化,为开始动笔做好准备工作,还要搞清题目的要求,以便根据不同的题材、体裁,写出不同格式,风格各异的文章,此外,还要注意人称、时态、地点等信息,避免出错。

三、抓住重点。寻求思路。

根据题目所提供的信息,草拟提纲,寻求逻辑次序,确定如何下手,否则,语无伦次的文章将不会被人接受,也不可能得到高分。

四、遣词造句,表达规范。

用词要适当,不可逐句把提示汉译英,亦不可生拼硬凑,不要硬拿英语单词到中文句子里去对号,否则写出中文式英语,闹出笑话。一般来讲,写作时,应尽量选出你有把握的词,尽量使用短句(简单句)。如果有的单词不会写,有的思想不会用英语表达,你可以设法绕开,最好找一个同义词、同义句,或近义词、词组短语来代替。要正确使用关联词,如and,or,but,so,because,since等,以便行文自然流畅。

作文写完之后,应注意检查修改,修改时先从全局修改。首先要检查主题是否明确,表达方式是否恰当,接下来检查所写内容是否切题,该交待的内容是否交待了,最后检查所用时态、人称是否符合要求,最后是否一致。

写完后,还应仔细校阅1—2遍。校阅要逐词逐句进行,注意检查语法、拼写、标点、大小写等方面的错误。校阅是自检的最后一关,应严肃认真的进行,尽可能地消灭一切差错,增强文章的效果。

因此,要写好一篇作文,不仅需要具有丰富的思想内容,掌握扎实的词汇、语法及修辞等方面的语言基本功,而且还需要掌握因不同思维方式和文化背景而形成的英语特有的篇章机构模式 惟有这样才能进行最有效的书面交际活动。

Unit Fourteen

The Lord and the Hermit

Once upon a time there was a rapacious lord. He was relentless to his tenants and quelled them by placing quotas to their living condition. Soon he collected quantitatively great revenue and lived in a radiate palace. He was also renowned for his queer clothes.

One day the lord’s disease relapsed, so he rallied his subordinates for help. One of them said: “I’ve heard of a recluse who knows regimen well residing nearby. Why not visit his residence for help?” Another retorted: “Be prudent, maybe it is only a rumor.” But the rash lord was filled with rapture and ratified the visiting plan.??

On the next Sunday, the lord purged himself, held a quaint rite and started for the hermit’s home. They passed rugged rustic passages full of paddles and the lord almost recoiled. Finally they arrived. The lord felt disappointed at the recluse’s reception, but he wouldn’t relinquish the chance and talked to the hermit with reverence.

The hermit ruminated and reverted to the main topic in a pungent voice: “I’ve heard lots of your ravenous deeds. You retract the land you’ve distributed to the farmers and order them to redeem their land. You must redress your guilt and rehabilitate their freedom. Reimburse their respective debts and build refuge for them. You can retain the residue of your property.”??

The lord was reluctant to renounce his wealth and be rent from his palace. He rebuked: “Your advice is too reckless. I’m resolute not to accept it.”

“Why so repulsive? You cannot repudiate my words.” The hermit reiterated his suggestion and its resonance echoed. “Remit their taxes with rebates, or a riot is imminent.”

The lord again refuted. At last he went back in remorse.

篇11:漫画说明文写作的“两段四步法”

全文共 1522 字

+ 加入清单

漫画就是用简洁而夸张的笔法描绘生活的图画,它极富幽默性与讽刺性。

怎样写漫画的说明文呢?我在教学实践中归纳出了“两段四步法”,具体模式是:

仔细观察,合理想象→切中角度,领悟深意一点明特征,讲究顺序→选择方法,推敲语言。

其中,前两步为第一段──读画,后两步为第二段──写画。

下面以华君武的漫画《公牛挤奶》为例,对上述模式作以具体解说。(漫画略)

一、读画 读是写的前提和基础,读透了,才能写准确、写扼要、写深刻。怎样读呢?

1.仔细观察,合理想象仔细观察,旨在掌握具体的富有特色的笔画,如公牛的双角、眼睛、鼻孔、躯体、尾巴等,如挤奶者的帽子、眉毛、口形、坐姿等,如瓶子的位置、形状。大小等。漫画简洁夸张的笔法常为观察者营造自由想象的天地,观察者会根据自己的生活体验,最大限度的发挥文学语言描摹出来。如:

被挤奶的公牛,惊弯了双角,回视挤奶者,其目光呆滞,鼻孔扩大,嘴巴欲张却合,哭笑不得;牛四蹄撑地,背部成弓,尾巴翘而难直的姿态完全是骚痒难忍所致。

挤奶者头戴一顶旧帽,眉毛倒挂,笑口难合,穿一身工作服,坐在小凳上,双手─下一下,潇洒自如的挤奶,俨然行家里手。

小瓶子馋奶张圆了嘴,空得干燥的肚子急盼慰藉,但久等的结果仍然是没有尝到半滴奶汁。

2.切中角度,领悟深意观察和想象的目的是为了搞清漫画的寓意。领悟漫画寓意,既是读画的难点,也是读画的关键。怎样领悟漫画深意呢?切中角度,反复揣摩,这是最佳方案。端讲煌趣爱好不同,生活体验不同,切人的角度就不尽相同,得出的寓意也就不完全一样,如:

从挤奶者切人:讽刺那些不进行调查研究就动手于事的主观主义者。

从公牛切人:讽刺那些受辱而无反抗精神的软弱者。

从瓶子切人:讽刺那些不择手段,合伙骗人的作案者。

教学中,应鼓励学生各抒己见,培养他们的发散思维和创造能力。

二、写画漫画的说明文写作之所以比较难,是因为它不仅要求学生要会卖、读懂,会说、说清,还要求学生要用准确、扼要、形象的书面语言表达出来。第一段的两步读,不仅突破了写的难点──寓意的领悟,而且为写作的重点──说明的方法和语言准备了充分的语言材料,这就变“难”为“易”了。怎样下笔成文呢?1.点明特征,讲究顺序 特征是事物之间的相互区别,是说明的中心。漫画的特征除了幽默性与讽刺性晕一共同特点画本身的寓意。动笔行文时,开篇点明寓意,不仅确立了说明的中心,使中心统领了材料,而且将自己与读者的思维控制在同一角度中。《公牛挤奶》一文的寓意,可根据写作的兴趣从一个角度切人,切忌面面俱到。开篇点题的构思,就确立了总→分→总的说明结构。分说时要讲究顺序,把画面说明得有条不紊,层次清楚,空间顺序是漫画的常用顺序,由上到下,由左到右,由主到次,等等,因图而异,因寓意而异,不拘一格,利于行艾,如《公牛挤奶》可从牛到人再到瓶子,可从人到牛再到瓶,还可从瓶到人再到牛,只要抓住特征,哪一种顺序,当然,应选最佳的顺序。

2.选择方法,推敲语言 只有选好方法,才能在具体说明时说得有趣又真实合理,行义中,应把平实说明与生动说明结合起来,要特别用好摹状貌和打比方的说明方法,用这两种方法时,必须推敲语音,力争语言准确、扼要、形象、幽默、风趣。要做到这些,读画中的“合理想象”是关键,只要能把想象说出来,再把抽象笔法变成文字材料,正式动笔行文时,就可集中精力对材料进行整理、编排、文字加工,语言关也就顺利通过了。

“两段四步法”是一种操作模式,对于初学者和中、差学生来说,的确是一大“法宝”,它可以驱逐作文时茫然而不知所措的畏惧心理,有步骤的构思行文,比较顺利的完成任务,但同时,它束缚了学生的思维,制约了学生的创造性,学生要排除其干扰,就需要一个比较长的过程对学生对模式的运用十分娴熟之后。

In China, the subjects that students learnt are necessary. They can learn special classes when they enter university. Sometimes I think it will be perfect to have the special class in middle school. On the one hand, students can learn more things besides the necessary subjects. They can develop more practical skills. On the other hand, students can cultivate their interest by learning something different. Though it is a little hard to open special classes, because education pays attention to scores, I believe that someday more special classes will be open, as the class reform calls on people to pay attention to the development of student mind.

在中国,学生所学习的科目都是有必要的。当他们进入大学以后,他们可以学习特色课程。有时我觉得在初中开设特色课程是非常好的。一方面,学生除了必要科目之外还可以学到更多的东西。可以发展更多实用技巧。另一方面,学生可以培养他们的兴趣,学习不同的东西。虽然因为教育注重分数导致开设特色课程有一定难度,但我相信总有一天将会开设更多的特色课程,因为教育改革呼吁人们关注学生的思维发展。

篇20:说明文的写作技巧参考

全文共 2902 字

+ 加入清单

说明文的中心鲜明突出,文章具有科学性,条理性,语言确切生动。下面是小编帮大家整理的说明文的写作技巧,希望大家喜欢。

写说明文和写其它文章一样,必须明确写作意图,确立文章中心;充分占有材料,力求做到言之有物、言之有序。除了这些一般性的要求之外,说明文的写作还有如下要求:

(一) 抓住事物特征,把握说明中心

任何事物都具有自身的质的规定性,一个事物的特征是区别于其它事物的标志。写说明文只有抓住事物的特征,才能把被说明的事物准确清晰地介绍给读者,让人们对事物有确切的了解。事物往往有方面的特征,介绍事物时,不可能在一篇说明文里面面俱到;只能根据需要,一次谈一两个特征。因此,要写好说明文,还必须把握说明文的中心。如:《漫活圆周率》是一篇介绍数学基础的说明文。文章题为“漫话”,并没有漫无边际地随意堆砌关于圆周率的材料,而是围绕求出圆周率的更精确的数值这个中心,向人们介绍了古今中外数学家对圆周率的数值所做的贡献。

抓住事物特点,把握说明中心,这是写说明文的一个重要要求,要做到这一点,写作者必须在写作前对被 说明的事物作深入细致的研究。必须懂得只有熟悉被说明的事物,认识并掌握被说明事物本身的规律性,才能做到这一点。

(二) 针对具体情况,选好写作角度

写说明文也是要求有的放矢的。写什么、怎样写,要从读者的实际情况考虑,使文章具有针对性,切合读者的知识水平、职业特点和年龄大小。往往读者对象不同,写的角度也不同。如阐述吸烟有害的说明文很多,有的是针对老年人的,有的是对妇女而言的,的有是对青少年而言的,角度不同,说明的内容则各有侧重。《青少年吸烟害处大》这篇文章从青少年是国家的未来和希望的高度介绍吸烟对青少年的危害,突出分析青少年的生理特征,说明青少年接触毒性物质比成年人吸收快、排除慢、毒害大的情况,指出“吸烟对青少年是绝对有害而无一利的”。这样说明目的清楚,针对性强。

写说明文选取什么角度要依实际情况而定。比如,介绍牛的知识,如果是为饲养者写的,要侧重介绍牛的生活习惯和特性;如果是为使用者写的,要侧重介绍牛的功能和力气;如果是为兽医写的,则主要介绍它的身体构造;如果是为食用者写的,可以主要介绍它的营养价值。当然,作为科普知识介绍,不妨全面一点为好。

(三) 务求解说清楚、做到条理分明

写说明文的目的就是让人获得知识的技能,只有解说清楚,才能达到这个目的。说明说明,一说即明,如何解说清楚,要讲究说明的方法,注意结构的安排,着力语言的运用。关于说明的方法,这里就不详细介绍了。这里着重讲讲结构安排的条理性问题。

文章的条理性是客观事物、事理本身的特点、规律在文章结构上的反映。说明文解说事物、阐释事理要按其本身的条理来安排说明的次序,使之层次清楚,主次分明,安排说明文的结构首先要注意条理性。如何具体安排结构,不同类型的说明文有不同要求,介绍产品制作过程的说明文,往往按照产品生产工序来安排结构,如叶圣陶的《景泰蓝的制作》是一篇介绍手工工艺品景泰蓝的说明文。它按照制作工艺的程序,抓住“做胎”、“掐丝”、“涂色”、“烧制”、“打磨”五道关键工序依次作了详细具体的说明,全篇言之有序,给人的印象十分鲜明。这一类安排,以时间变化为序,着重写事物的过程。

(四)语言准确简明,文字通俗浅显

选用准确的语言,精当地解说事物的事理,是说明文语言的基本要求。说明文是以介绍知识性内容为主的,只有如实反映被说明内容的客观情况,才能保证知识的科学性。相反,语言不准确就会失去知识的科学性。

明代学者徐光启笔译古数学家欧几里得的《几何原理》,其中的一节:

凡论度必始于一体。自点引之而为线,自线广之而为面,自面积之而为体,各自三大纲。是心有长而无阔者谓之线,有长与阔而无厚者谓之面,长与阔厚俱全者谓之体。唯点无长阔厚薄,其间不能容,不可以数度,然线之两端即点,而线面体皆由此生。点虽不入于数,实为从数之本。

这节解说数学基本概念的说明文,把什么是点、线、面、体,点与数度的联系和区别作了确切的阐释,语言也很精当。

此外,在说明文中往往有些内容是带有专门化的科学知识,涉及一些专门名词和专业术语,在说明中特别要求把它们运用得准确无误,使读者便于领会。如:“航空”与“航天”是两个不同的概念,有篇文章作了这样的解说:“飞机在大气层内飞行,称为航空;卫星、飞船在大气层外飞行,称为航天。它们是采用不同的飞行器在不同的空间来完成飞行任务的”。这种解说是十分准确的,使人对什么叫“航空”、什么叫“航天”得到了科学的了解。

说明文的语言必须简要精当。看下面的这段文字:

“蝉的幼虫脱皮是从背上开始的。先出来的一层旧皮从背上裂开,露出淡绿色的蝉来。先出来的是头,接着是吸管和前腿,最后是后腿和折叠着翅膀,只留下尾边尖儿还在那层旧皮里。这时候,它腾起身子,往后翻下来,头部倒挂着,原来折叠着的翅膀打开了,竭力伸直。接着,用一种几乎看不清的动作尽力把身体翻上去,用前脚的爪子钩住那层旧皮。这个动作使它的尾巴尖儿从那层旧皮里完全脱出不了。那层旧皮就只剩下空壳,成了蝉蜕,。从开始到完全脱出来,大约要半个钟头。

这段文字不到二百个字,具体说明了蝉的幼虫脱皮的整个过程。用简明的语言把幼虫脱皮的复杂动作细致而真切地写出来了。文字不枝不蔓,语言富有表现力,给人很清晰的印象。、

说明文要介绍一些科学知识和一些内容,往往是一般人所不熟悉的内容人,要把专门化的科学知识解说清楚,让人易于了解,必须做到深入浅出,通俗易懂,生动活泼,富有趣味。如,《洲际导弹自述》是一篇介绍洲际导弹知识的科技小品。文章用拟人化手法把洲际导弹问世、分类、构造、特点及其威力和弱点都解说得十分清楚,文章把它赋予假定的人类行为,读起来生动风趣,易于理解。为了把说明文写得生动活泼、通俗易懂,人们常常运用各种修辞手法,增强文章的形象性、趣味性。

在说明文的写作中,应该注意克服几种常见的毛病。这就是:

第一,防止知识性的差错。如有篇写“牛”的习作这样写道:“牛有水牛、黄牛两种,牛是反刍动物,只吃青草,不必喂料。牛都两只角,体强力大,是世界各国普遍使用的耕作工具。”由于写作者对有关牛的知识了解不够,有些只是一知半解。所以写起来造成知识性的错误。世界上牛的品种不只水牛、黄牛两种,杂交品种的牛并不长角;除了青草外,还必须给牛喂其它饲料;世界上也不是普遍使用牛作为耕作工具,牛还有专供食用、奶用或运输用,甚至作为神物崇拜的。

第二避免文体性的错误。如有篇说明文题为《蚯蚓》,其中写道:“……别看这小动物不惹眼,它可天天在松土、干活,它不讲究吃穿,不讲究休息,不讲住的,不讲报酬,整天埋头苦干,为人们劳作耕地,让作物生长茂盛。我不禁想起我们的老师,他们也有蚯蚓精神。

我愿作一条辛勤劳动的蚯蚓。”

显而易见,这篇习作把一篇说明文写成了一篇借物咏志的抒情散文了。

第三,克服片面性的论述。如,有篇题为《青蛙》的知识小品,介绍青蛙时写道:“青蛙是两栖、变温的动物,营养价值很高,……”这样定是片面的,青蛙能捕捉害虫,有益于庄稼的生长,只写它营养价值高,不宣传要保护它,饲养它,必然会造成不良社会影响。片面性是不利普及科学知识的。
