Teacher is a great job in most students’ eyes. When they are asked what

they want to be in the future, most will say they want to be a teacher and make

a contribution to the society. Indeed, we have access to the teachers all the

time and they have great influence on us. So being a teacher is a ideal job for

most students, but for me, I want to be a librarian. I like reading books so

much and once I have time, I will be immersed in these novels. Books broaden my

vision, though I can’t travel to the places, I can still know about these famous

sites from these books. Being a librarian can make me have a lot of time to

read.

English is widely used throughout the world.

So many people speak it as a second language. Online, youll find lots of

information in English. If you dont understand English, how can you know more

about the world, how can you get more knowledge. At international conferences,

English is also used as the official language. Without good English, you cannot

express your ideas well at such conferences, neither can you introduce China to

the outside world.

[初中毕业英语作文自我介绍

When the national entrance examination is over, people always pay more

attention to those who are enrolled by colleges and universities. Those who

failed the examination are treated coldly. Being enrolled by colleges and

universities is, of course, worth congratulating. But giving the successful

candidates excessive praise and neglecting those who failed the examination

might send the wrong message: young people do not have a bright future unless

they go to college or university.

Teachers, parents and society, therefore, should give more attention to

students failing the examination. They are in more urgent need of understanding,

warmth and encouragement. We should tell them that to go to college is not the

only way to success, and that, if they make enough effort, they can still

develop talents in other occupations that will serve society.

Personally, the country’s economic development requires not only

specialized scientists and technical experts, but also knowledge-based workers

and skilled laborers. After some vocational training, these senior high school

students can also become backbones in their own fields and contribute their

wisdom to our society.

对于考研英语的应用文写作来说，考生平时复习时不仅要注意应用文写作特点、格式要求，还要有意识的掌握各类应用文的写作方法。考研辅导专家建议广大考生不要简单认为应用文的复习就是复习相应的格式，格式只是应用文写作的最起码要求，除了应用文特定的格式外，还要背诵一些经典的套话，在平时的写作训练中培养迅速构思成篇的能力，注意词句的多样性和准确性训练。下面，我们就针对应用文写作中的私人和公务信函、备忘录、摘要、报告几种形式介绍一下写作技巧。

一、私人和公务信函

信函是很重要的一种应用文。私人和公务信函是用以交涉事宜、传达信息、交流思想、联络感情、增进了解的重要工具，与同学们的生活、学习比较密切，也是以后工作中用的最多的一种沟通方式。所谓私人信函就是给家人、朋友或者同学等写信，谈事情的同时又交流感情，是四级考试(专业课历年考研试卷)中常见的一种信函，研究生英语考试(专业课历年考研试卷)中常考的是公共信函。所谓公务信函就是给亲朋好友之外的人写信，主要是为了办事，比方说给老板或是客户写信都属于公共信函。

信函一般都是由写信时间、信内地址、称呼、信的主要内容和信尾几个主要部分组成。收信人地址要写在左上角，寄信人地址要写在右上角，寄信人地址也可以不写，姓名写在地址上面，地址排列顺序依次为门牌号、街区名、城市和国名。在信的开头人名前一定要加Mr.,Mrs.,Dear等比较尊敬的称呼，信的结尾注意使用常用的客套话如：sincerelyyours,faithfullyyours或者yourssincerely,yoursfaithfully。英文书信写作要遵循五个原则，即正确、清晰、简洁、礼貌和体贴。

正确是指信中所谈的事情要准确、具体，不用含糊抽象的词如：本月、明天等。清晰要求的是主题要明确，层次要清楚，让读者看后了然于心。简洁是现代英语发展的一大趋势。书信写作要做到行文简洁流畅，避免迂回冗长的长句，使书信尽可能写得明白清晰。书信交往，同样需要以礼待人，因而在写信过程中，要避免伤害对方感情，措辞上多多使用would,could,may,please等词，要自然得体，彬彬有礼。体谅对方也是写书信时要注意的一个原则，不能以自己为中心，要尊重对方的习俗爱好，即便是拒绝，也要委婉而不失去友谊。书信的写作也要注意格式，避免语法、拼写、标点错误，信中所引用的史料、数据等也应准确无误。

二、备忘录

备忘录是一种录以备忘的公文，主要用来提醒、督促对方，或就某个问题提出自己的意见或看法。包括书端、收文人的姓名、头衔、地址，称呼，事因，正文，结束语，和署名，备忘录上一定要说明什么时间，谁写的？写给谁？什么事？并且正文、结束语和署名等项与一般信件的格式相同。

三、摘要

接着谈谈摘要。摘要分成两种，一种是文章摘要，一种是论文摘要。

文章摘要就是给一篇文章让写一个摘要，文章摘要是对文章主要内容的简练概括，内容上要涵盖全文，语言上要尽量简练。写摘要前一定要仔细阅读全文，弄懂文章大意；摘要涵盖原文的主要观点并与原文的观点保持一致；摘要应该简明扼要，字数在规定的字数范围内；摘要最好不要照搬原文，应该用自己的话概括原文的主要观点；并且注意千万不要照抄，也千万不要评论，只需要写出中心思想或者段落大意即可。

第二种摘要是论文摘要。比方说是大家写一篇学术论文，硕士博士论文需要写一个英文的摘要。相对来讲我们认为考论文摘要的可能性稍微大一点。写这种摘要时要注意时态和语态。叙述研究过程，多采用一般过去时；说明某课题现已取得的成果，宜采用现在完成时。摘要中多数情况下可采用被动语态。但在某些情况下，特别是表达作者或有关专家的观点时，又常用主动语态。英文摘要有一些常用句型，比如表示研究目的，可以用Inorderto……Thispaperdescribes……Thepurposeofthisstudyis……，表示表示结论、观点或建议可以用Theauthors[suggest/conclude/consider]that……。

四、报告

最后一种是报告。报告其实也分为两种，第一种是读书报告。比如读一本书或者看一本小说写一个读书报告。读书报告中首先要交代背景知识，比如作者生平，时代简介等，接下来对书的内容做一个简单的概括，与摘要不同的是读书报告最后一段可以发表评论。与摘要相同，读书报告也要注意时态，比如像科普类的知识应该用现在式。另一种报告就是书面报告，书面报告考试(专业课历年考研试卷)的可行性和可能性更大一些。书面报告与备忘录的写法很类似，所不同的就是书面报告一般是下级写给上级，它也需要交代清楚四件事：什么时间？谁写的？写给谁？什么事？

当然，应用文写作能力的提高必须经过长期的实践锻炼。在复习阶段，首先要熟悉不同类型的应用文写作格式，注意事项，写作特点等。其次要背诵大量的优秀范文，要整段整段的背，不仅是背会而且要脱口而出，并且转换成自己的语言，写作时可以随心所欲支配。再次，是要多动手写作，要写出属于自己的文章，多动手写作才能快速写出好文章来。写好的文章要注意检查，看有无语法错误，有无用词不当，能否用其他的句式表达相同的意思，可以让同学帮忙检查，让同学提一些宝贵的意见和建议。总的来说，虽然大家对应用文的写作还比较陌生，但是只要认真对待，只要花时间背范文了，花时间写文章了，就一定能取得理想成绩。

Happy summer vacation is coming, von teacher (tutor) gave me an essay:

"summer fun".

Filed a summer vacation, I will be very excited, because the summer can be

more happy, in retrospect, they like the movie playback in my head.

Photos, I looked at my to hainan emerge previous scenario in your mind:

beautiful had a stretch. I observed a look, my dad is still sleeping, but I

cant wait to go to dinner to the beach. I call my father. After dinner, we came

shovel to give him one layer built a wall, tired of the sand can be high. Very

tired ah, look at me "big project" my heart very happy.

Oh, what a wonderful memory. I found that life is not good thing is much,

but to myself.

从每年的考试情况来看，很多同学能完整地按照要求把文章写出来，但得分却较低。实际上，高考英语书面表达是一个分值颇高且易得分的题型，只是很多同学没有掌握得分技巧。下面我们一起看看怎样才能让高考作文拽起来。

一、几点重要原则

1.智者利用押题，傻子依赖押题!

2.书面表达整篇背诵绝无必要，可以以看读为主，关键是从中汲取一些常用的词汇和表达，并能得体熟练地运用。考场上应变能力很重要!

3.英文写作模仿很重要。有时也很有效。但不能过于牵强，尤其是对一些长难句的刻意模仿使用。

4.文似看山不喜平，起承转合一定要有!

5.见微知著，一叶知秋，几个亮点足矣：有道是：浓妆淡抹总相宜，作文写得简洁到位要比长篇大论更显功力。

6.心不为形役。不要身陷逐字逐句英汉对号式的字面翻译，要把表达的主动权始终握在自己手里。

二、善用万能句以不变应万变

历届高考，书面表达考得最多是提示作文，即提供一定的情景内容，要求考生完成100词左右的短文。

从命题方式看，有短文提示、要点提示、图画提示、情景提示以及图表提示等；体裁以应用文为主，记叙文为辅：题材为广大中学生所熟悉的日常生活。从提供要点的情景方面看，历届高考书面表达题均属供料小作文，采用文字供料或文字说明加图画(图表)的方式供料。

备考时，同学们要利用有限的时间把以前背的范文整理一下，从中选出不同体裁、不同题材的范文各一篇(范文以高考真题的高分作文为佳)，把它们重新记忆，一定记牢。这样，高考时不管什么样的文章都可套用背诵好的格式。避免考场上因紧张而无章可循。

最后阶段，还要总结一下写作时常用且能出彩的固定句型、句式，比如强调句型、定语从句、名诃性从句等，牢记英语的五个基本句式，背诵平时老师总结的万能句。以不变应万变。

考场答题前，应仔细审题，研究所提供的文字和图画(图表)材料和作文要求。分析、提炼要点，理顺要点，确立基本的写作思路，不要忽略任何一个词。关键的词更不能遗漏，构思好写几个方面，缺一不可。

写作时，尽量用学过的英语句型和词组。少写长句和复杂句以免弄巧成拙、漏洞百出。但目前高考有关书面表达的评分标准要求作文中应有较多的语法结构和词汇，因此同学们在书面表达中不能都写小句、短句和单句，还要正确运用高级词汇和复杂结构。恰当运用过渡词，使写出来的文章含金量更高，更具可读性。

三、高分作文六大特性

1.条理性。指的是合理安排文章结构。首先，在文章思路、组织材料、叙述顺序等方面要有一定的条理性。其次。根据需要，安排好段落，各段之间要层次分明，也要重视每一段的开头和结尾，开头语往往是总起句，结尾语往往是总结句。

2.准确性。指要求写出语法正确的句子，包括时态、语态、用词和句法等，要准确、地道地表达。必须要牢牢掌握一些常用句型或习惯表达，避免中式英语，在实践中不断总结中英用法的差异，养成用英语思维写作的习惯。

3.流畅性。指根据整篇文章思想的需要，有效采用不同的连接手段，使文章层次清楚、行文连贯。

4.简洁多样性。简洁性就是语言简洁，不重复。多样性就是能随情景内容的变化写出句式多样的语句。这也是新课程标准对写作的评价标准。

5.思想性。新标准对写作的要求，增加了情感因素，在准确流畅表达写作要点的同时，适当增加句子的感情色彩，增加一些人情味，使文章读起来更亲切，完全达到与读者进行交流的目的。

6.美观性。指的是卷面书写规范、清楚、干净、整洁。

四、怎样才能有拽的感觉

1.高考写作的实质变相考查句型与词汇的灵活应用

英语写作不同于语文作文的写作，如果说语文作文是一个自由发挥的舞蹈，那么高考英语写作就是带着枷锁在跳舞。我之所以这样来形容，是因为高考英语写作的内容都已经通过文字、表格、图片这三种形式给定，内容方面，不需要学生进行发挥，大家所需要发挥的就是不要老去给这个不变的内容穿毫无变化的校服(简单句)，而要去穿一些不一样的衣服，让它显得不那么单调，让阅卷老师能看到不同，而那些所谓的衣服也就是多变句型与词汇。

2.写作的评分标准怎么去迎合评卷老师的胃口

我了解到目前很大一部分学生的作文都处在15分左右，写作满分25分，15分也就是个及格分，那么15分和20多分的作文到底差在哪里?这个问题很容易回答。15分的作文中规中矩，该对的都对，包括内容要点的完整，语法与词形的正确，但是全都是简单句子的堆砌，没有任何亮点。而20多分的作文在句型词汇方面就做了很好的包装，它的句子穿的衣服已经不是校服，而是李宁、耐克，或者是阿迪，所以让人觉得很拽，而高考英语写作要的就是这种很拽的感觉。

3.写作提分的三要素句型。连词。高级词汇

句子是我们写作文最大的单位。有了漂亮的句子。用好的连词将其连句成段，再加上一些如星星般亮点词汇的点缀，一篇好的高考英语作文就诞生了。而这三个因素中最容易把握的是句子，最难的是高级词汇，限于大家的词汇还比较有限。一篇文章中出现那么一两个就够了。我们应该把重心放在句型上，因为这个最容易把握。

但是大家又有这样的困惑，学校里老师也给了我们很多的句型啊，动辄成五十上百句的，大家背得挺多，但是面对考试的时候，发现背的那些怎么也用不上。其实不是那些东西没有用，而是它们太干了，就好比一根干骨头，大家嚼起来很没有味。也不知道该把它们往哪里放。

在这里我给大家提供一种比较切实可行、迅速提高的练习方法，在接下来的时间里只要大家按照这个方法来，就一定会有收获。

找出历年真题，一周只需要写两篇。但是要这么来写。

1.把你要写的内容要点用九到十句的汉语表达出来。

2.逐一地进行翻译，不是用简单句。而是要刻意地去想：

(1)可以用什么样的复杂句；

(2)怎样去避开不会的表达，转义。

例如：

这本书是如此的有趣，以至于我读了一遍又一遍。

1.This book was so interest，ing that l read it again and again，

2.This was such an interest，ing book that l read it again andagain，

3.This was s0 jnteresting abook that l read it again and again

4.So interesting was thisbook that l read it again and again

这四句译文当中无疑评卷老师最欣赏的是第四句，因为它用了倒装。

4.如何备考

其实这种思维大家都有。但是没有成为一种思路，让它能在考试中起到作用，那是因为大家练得少。英语写作处在一种很尴尬的境地，一方面大家要分数。但另外一方面大家一个学期里写的作文也就是期中期末的两篇。毫不夸张地说，有的学生上了三年的高中可能只写了六篇作文，所以练习是很重要的，要是现在不练而把高考当练习。那么作文只拿14、15分也合情合理了，到那时你不要骂评卷老师不公平，而应该问问自己备考的时候为什么不多练几篇。时间都是挤出来的，希望大家可以挤出时间来练写作。

I am like a rickety boats and ship in the ocean of knowledge in, almost cant find any knowledge of the pearl. And the teacher like an experienced mentor, guide me into light waters.

How many night, whether it is a sunny sky, or the north liUxue86.com wind shout, your room is always reveal a narrow beam of light. You for our quarrel, you happy, for us a little bit of progress every move you do, you say every word, is for us and our future.

The teacher taught us not only knowledge, but also the true meaning of life: people without health, let alone learning, more not as something different. So, we must not to pursue a minor, and delayed the most important, of course, important good, minor or want to pursue.

Who is vomiting for us through the blood, wire is who died for us to try? He had a cordial and loud title - a teacher!

我就像一艘摇摇摆摆的小船，在知识的海洋里乱荡着，几乎找不到任何知识的珍珠。而老师就像一位经验丰富的导师，指引我向光明的海域划去。

多少个夜晚，无论是星空晴朗，还是北风呼呼，您的房间总是透露出一束微弱的光。您为我们的争吵而烦恼，您为我们一点点进步而高兴，您做的一举一动，您说的一字一句，都是为了我们与我们的未来。

老师教我们的不仅仅是知识，更是人生的真谛：人如果没有了健康，就谈不上学习，更加谈不上有一番作为。所以，我们不可去追求一个次要的，而耽误了最重要，当然，重要的不错了，次要的还是要去追求。

是谁为我们呕心历血，是谁为我们春蚕到死丝方尽?他有一个亲切而又响亮的称号——老师!

考研英语应用文写作范文之感谢信感谢信

结构要点感谢信是就某事向收信人表示感谢的信件，分为三个部分：

1． 指出对方帮助自己的事情，表示感谢；

2． 展开叙述这件事；

3． 再次感谢，并可表示希望回报对方。

Suppose your were recommended by Professor Sun to get further education in Yale University last June and now you have been admitted by that university. Write a letter to Professor Sun to express your gratitude in about 100 words. Do not sign your own name, using “Li Ming” instead.Dear Professor Sun,

I am writing to extend my gratitude to you—without your help I would not have been a postgraduate student of Applied Mechanics Department of Yale University.

Last June, you helped me with no reservation when I applied for Yale University. You wrote a recommendation letter for me to Professor W, the dean of the department. You gave me instructions on how to fill the application forms and write the application letters. Whats more, you also taught me how to take care of myself and get along with others, which I believe are lifes great lessons.

Your help enabled me to fulfill my dream to pursue my studies in a great university. In the following days I will remember what you have told me and work and study hard to be a capable, conscientious and responsible person.

Yours truly,

Li Ming

感谢信

语言注意点感谢信应充分表达自己的谢意，切不可给对方草率的印象。可借助谈对方的帮助来进一步表达感激之情。言辞应真挚、得体。

Suppose you were taken good care of by Aunt Sun when you pursued your studies in Los Angels where Sun lived. Write a letter in about 100 words to extend your appreciation. Do not

sign your own name, using “Li Ming” instead.Dear Aunt Sun,

It is a great pleasure to extend my sincere gratitude to you for your hospitality and consideration while I pursue my bachelors degree at University of California.

As soon as I arrived in Los Angeles, you found me an apartment near my university. When I met with difficulties you often sent your daughter to help me and when I felt homesick you often talked to me patiently. You told me how to improve my efficiency in both work and study and how to get on well with teachers and schoolmates. Furthermore, you invited me to dinner on nearly every weekend.

Without your help, I would not have graduated with honors and found a satisfactory job back here in China. I know I can never repay you for everything you have done for me in the past four years, but you can be sure that I

Best regards.

Yours faithfully,

Li Ming ll never forget it.

The winter holiday is coming. I am very excited. I want to better my

holiday plan. Now let me tell you my plan.

I’m going to read some books and listen to music and relax for a few days

first. On the fifth day, I’m going to do my homework. Of course, I’m also going

to do some housework. Lunar New Year’s Day, I’m going to take a trip with my

parents. I think it must be very happy. I can hardly wait! In the first six days

of February, I’m going to visit my relatives. It’s going to be fun! After a few

days, I’m going to finish my homework, because I am going back to my school on

February 16th.

Generally speaking, life in high school is busy and fulfilling, due to the

ultimate goal---College Entrance Examination. Many people say that there is no

fun left but bored study and endless exercises. However, as a high school

student, I can’t agree with them. Personally, I live a fruitful but happy life

in high school. It can’t be denied that study is my priority that I must spend

most of my time and energy on it. Sometimes, study may make me frustrated or

even drive me crazy, but I still can adjust my mood to enjoy my life. Besides, I

can also get a sense of achievement when I do well in my study or make progress.

The most important is that my friends bring much happiness to me and my parents’

care inspires me to go on. I think friends in high school are my best friend

forever, because they know me a lot and witness all of my emotions. They are the

persons who grow with me. In addition, teachers in high school care much about

our students both in study and life, and classmates are always friendly to each

other. We build deep friendship together. All of these make up my fruitful life

in high school, which I will cherish forever.

在学习英语写作之前先来看下练习写作对你的英文有什么样的帮助：

好处1、辅助提升口语语言组织力

好处2、提升语法

好处3、帮助背单词和句型。

了解到联系英语写作带来的好处后让我们来看看学习英语写作有哪些方法：

零基础英语写作入门方法一：背单词

单词是英语写作的基本构成之一，拥有大量的词汇才能写出你想要的文章，背单词有很多方法用mp3在零碎的时间边听边背边写，还有单词前后缀记忆法等众多方法，只要掌握其中一种适合你的方法，就开始大量的充实你的词汇吧。

零基础英语写作入门方法二：语法

语法是将单词串联在一起变成文章的那根线，学习好语法是整个英语阅读的重中之重。推荐熟读语法俱乐部，同时搭配大量的阅读自己感兴趣的文章，在大量的语境中去领受感悟本书的妙处。

零基础英语写作入门方法三：长时间的练习

写日记，这是最简单最长久的写作练习你不需要有任何的准备，这是你会接触到最基础的写作练习，你可以写任何你感兴趣的事情，你要做的就是拿起笔和本子把自已生活上的点点滴滴用英文记录下来。下面就是我的第一篇英文日记！

"today i rest,i stayed at home.sister call me go to the mother.i want not go there,because i must go to the company .去领 clothes.刚刚上完课come back.at home i find my 皮 shoes.now 要穿皮shoes了,write 日记好搞笑，还可以写点english了,i believe 以后 i sure i会更好。”

大家可能会看不懂这篇文章。你可能会觉得很好，说老实话当我现回过头去看我以前的日记我看了也觉得很好笑。但这就是我的第一篇英文日记，我的英文写作就是从这里开始的。你会发现写得非常直白，简直就是中文翻译毫无语法可言。但没有关系每个人开始都是这样的。

在写日记的开始阶段，你可能会像我这样不知道怎么去写或跟本无法组织语言，你可以像我这样按自已大脑里中文的想法去写，把会的单词都写上去不会的就用中文代替。在这个阶段你更多的是在使用你所学的词汇，有时候你会觉得这样很好玩。每天坚持写一篇，慢慢的你会发现你用的中文越来越少了有时候整篇文章都可以用英文写出来，随着你英语学习的进度不断推进，你在写句子的时候你不会直译了，你开始吧语法考虑到你的语言组织里面去。

当你要表边一个句子又找不到这个单词的时候，这种映像会深深的印在你的脑海里，当你在收集单词时候你就会注意收集那些非常实用的单词了。你会背更多的单词因为你想终有一天我的整篇文章是用英文写的。对于初期的写作，我认为就是这样写吧，请注意兴趣的培养。

①1782年4月，法国巴黎的一位采石工人劈开了一块巨大的石头，眼前的一幕让他惊呆了：石头里面藏着4只蟾蜍，它们竟然都还活着。石头被劈开后，这4只蟾蜍蹦了出来，看起来还很有活力。

②科学家对这里的石灰岩层进行了科学测定，证实它们形成于100多万年之前，也就是说这4只蟾蜍在石层中已经冬眠100多万年了。

③这件事让人们大为惊诧，这4只蟾蜍竟然能活100多万年！它们是怎么在这100多万年里保持着生命的活力的呢？

④我们谁都渴望长寿，可是人类和其他动物的寿命都是有限的。一只狗可以活15年到20年，一匹马可以活30年到40年。无论是人类还是动物，生命都是有限的。一般来说，人的生命极限为200至250年，而普通的蟾蜍的生命极限也只是10年。

⑤可是这4只小小的蟾蜍竟然能够挑战生命的极限，存活了100万年，这令人唏嘘不已。

⑥面对这样的生命奇迹，人们不禁要问：“在如此漫长的时间内，这些蟾蜍在没有食物、水和阳光的环境下，是怎么维持生命的呢？这些能生存百万年的老寿星们，它们是怎么修炼出长寿秘诀的呢？”

⑦有科学家分析说，可能是这些动物在冬眠的时候地壳发生了变动，它们所在的淤泥变成了岩石，这些岩石虽然看起来很坚固，其实存在着不少微小缝隙，所以水分和空气都能够进入岩石中，它们便可以生存了。但是，动物要维系生命，还需要一定的热量，尽管蟾蜍或青蛙在冬眠时热量消耗非常低，但它们自身的热量，无论如何也无法维持数千年甚至数万年之久啊！

⑧有科学家解释说，蟾蜍能经过上百万年仍有生命体征，得益于它们生存在一个保持“恒温”的环境下。封存它们的岩层或矿层就是这样一个恒温的环境。在这样的环境下，它们不会受到任何外界的刺激，天气阴晴冷暖、四季交替对它们都没有什么影响。蟾蜍实际上等于把生命贮藏了起来，不进行新陈代谢，不消耗能量，所以能长期不吃东西而不死亡。

⑨还有科学家认为，蟾蜍长寿是因为它们体内有一种甘油在起作用。美国的一位科学家就曾做过这样的实验：他先把几只快要冬眠的青蛙放到零下6度的环境中，一周之后，他给青蛙慢慢地提高温度解冻，并检查青蛙的肌肉成分，结果发现它们的肌肉中多了一种甘油。所以他认为，蟾蜍在冬眠时，由于体内产成了一种甘油，所以才能长久不死。

⑩另有一些科学家认为，上述解释都还不够充分。迄今为止，对于蟾蜍和青蛙如何长久维持生命的问题，科学家们还没有形成一致的结论。但随着生物科学的迅速发展，相信这个谜团最终会被解开，这可能还会对研究人类长寿问题有启迪和借鉴作用呢。

(选自2014年2期《学生天地 》初中版)

1.对于蟾蜍在没有食物、水和阳光的环境下得以长寿的原因，科学家有哪几种解释？请作简要概括。

2.选文第③段中加着重号的“这件事”指代什么？

3.选文第④段加线句运用了什么说明方法？有什么作用？

4.简析第⑩段加着重号的词语“可能”的作用。

参考答案：

1.①包裹蟾蜍的岩石存在着不少微小缝隙，水分和空气都能够进入岩石中，蟾蜍便可以生存了。②蟾蜍生存在一个保持“恒温”的环境下，不进行新陈代谢，不消耗能量，所以能长期不吃东西而不死亡。③蟾蜍在冬眠时，由于体内产成了一种甘油，所以才能长久不死。

2.4只蟾蜍在一块巨大的石头里活了100多万年。

3.用列数字的说明方法，真实具体地说明了一般动物的寿命是有限的。

4.“可能”表推测，说明蟾蜍长寿谜团被解开，也许对研究人类长寿问题有启迪和借鉴作用，“可能”体现出说明文语言的准确性、科学性特点。

那一年夏天，我回到了家乡。来到一块空旷的草地上，看到了许多萤火虫。我就想萤火虫为什么会发光呢?难道它屁股后真的有一盏灯?

经过我多次地去找资料，得出了结论：

萤火虫屁股后不是有一盏灯，而是由化学与生物学联合起来解决的。原来，这是成光蛋白质与成光酵素在变把戏。

成光蛋白质是一种点不完的“灯油”：当萤火虫的尾巴上亮一下的时候，就是成光蛋白质，在成光酵素的作用下，与氧发生作用，变成含氧成光蛋白质，而射出绿光。

因为萤火虫几乎把95%以上的化学能量，都用来发光了。所以这种光，叫做冷光。

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。

“Score is not equal to knowledge,” my head teacher always keeps telling me this, because he wants us to master all the knowledge we need to understand. I do not put his word in mind, because in my heart, score comes the first.

One day, chemistry teacher taught us some knowledge and then asked us to finish a paper test.

Whoever passed the text can do the experiment. I got a high mark by guessing.

I was very happy, but tragedy happened. I made a small explosion by not mastering the knowledge. I was scared and finally understood the sentence,” Score is not Equal to Knowledge.”

“分数并不等于知识，”班主任对我说，因为他希望我们能够掌握所有需要了解的知识。我并没有把他的话放心上，因为我觉得分数是最重要的。有一天，老师教了我们一些知识，然后就让我们考试。只要通过了考试才能去做实验。我瞎猜猜得了很高分。我很高兴，但是悲剧也就发生了。因为知识不牢固而导致了一个小爆炸。我被吓到了，也终于明白了那句话，“分数并不等于知识。”

[初中英语作文：分数并不等于知识

He always rose early to enjoy at least two hours of solitude in the house

and garden before the rest of the family came down In winter he spent most of

the time reading and writing. In sum mer he liked to get out of doors to work in

the kitchen garden or to take the dog for a walk in the neighbouring woods and

fields Whatever the weather, there was plenty to occupy him.

Although he was a creature of habit, there seemed to be an infinite variety

in his pursuits. He wrote book reviews regularly for two of the national

weeklies. He worked conscientiously his special subject, Indian History, and was

thus one of the world authorities on it;

he collected modern abstract paintings and so had a circle of friends

amongst artists and sculptors; there was hardly anything he did not know about

traditional jazz and he often entertained both British and America n jazz

musicians He was a superb cook and knew a lot about French and German food.

His family adored him and in a sense he was spoiled by them. At first

glance you would have taken him for a retired army officer-his bearing was

erect, his hair was cut short, he was fussy about his clothes, which were always

neat, clean and conventional. He liked to keep fit, and this was reflected in

his clear, steady blue eyes and healthy suntanned complexion. He hardly ever

watched TV, but enjoyed a good film and an occasional evening at the

theatre.

Failure exists in every stage for everybody. As students, I think the most

common failure would be failing in the exam. Yes, I have failed in the exam for

many times. It is very common, because on one can keep the name of

ever-victorious generals forever. But some students do not figure out this. When

they fail in the exam, they need a long time to recover, even have directly

negative effect on their inner heart. This is not the right way to deal with

this problem. We need to figure out the reason why we don’t do well in the exam.

And then correct it. Try our best to get better next time.
