作為一個中學生我雖不能搞什么大的發(fā)明創(chuàng)造，但是面對神奇的科學領域，我依然心存美好的遐想。我也想在這暑假學習一些科學知識，這是多么有趣味?。∷晕铱戳艘槐?《學生探索百科全書》?！八季S是地球上最美麗的花朵”，而探索精神是其中最燦爛的一枝。千百年來，人類用孜孜不倦的求索精神，不斷擴展著對神氣大自然，對奇妙的科學以及對人類自身的認識。在永不停頓的對未知領域的探究中，人類建構(gòu)起了多姿多彩的迷人世界。

人類是怎樣進化的？太陽還有多少壽命？我們能否走出地球？真的有外星人嗎？種種問題令我不解，為了解開這些我不懂的“迷”我選擇了《學生探索百科全書》，我希望它可以給我?guī)磉@些我不懂得的問題的答案。

科普讀物讀后感這本《學生探索百科全書》共分為三章——自然探索、科學探索和歷史探索。三章的排版都做的很好，讓讀者很容易便可以找到自己感興趣的知識，三章都按照各自的特點分為若干節(jié)，各節(jié)在結(jié)構(gòu)設計上均采用場面宏大的主圖以及精彩紛呈的配圖以增強視覺沖擊力，讓讀者在準確的文字描述、嚴謹?shù)脑斫沂局杏淇斓靥ど闲缕娴奶剿髦?，輕松地掌握的百科知識。讀過這本書之后我深深感受到了它對我?guī)淼暮锰帯?/p>

首先我在第一章的自然探索中，我了解了來自宇宙深處的信息、漫長的生命之旅在第二章的科學探索中，我了解了無處不在的黃金分割、四色之迷、尋找“幽靈粒子”、我們能不能穿越時空……，這些知識又是我了解到了科學，學會了科學的方法，科學的理論，科學的發(fā)展，科學的分析這些重要的東西，并且在日常生活中遇到的一些奇聞異事我也可以通過科學說法來解答他，這些知識都豐富了我的生活經(jīng)驗，讓我不斷的健康成長。在第三章的歷史探索中，我了解到了絲綢之路、奧林匹克運動會的起源、埃及艷后、金字塔工程……歷史使人明智，因為了解歷史，可以學習前人的正確做法，并且改到自己的錯誤作風，這樣可以使人們在成功的路上少一些坎坷，為自己鑄造一條平平的道路 書是知識的源泉，能教給我們許多知識。一本好書，不但可以激發(fā)學習的欲望，而且還可以開拓眼界，它就像一位無形的老師，幫助我們筆直地走在人生道路上。我們應該懂得知識的可貴，少玩一次游戲，少看一次電視，經(jīng)常讀有關(guān)這方面的書，頭腦中產(chǎn)生的疑問才會越來越少，興趣也就越來越高。同時還可以獲得更多的知識，更多的學問，更多的人生道理！

此外，我還清楚的認識到科學精神是人類一切創(chuàng)造發(fā)明的源泉，是做人做事、處人處事的根本。有了科學精神，遇事都要問個為什么，決不輕信盲從；有了科學精神，凡事都會講究真確，決不隨波逐流。為了便于記億，我們可以把科學精神歸納為八個字：“求真、務實、無畏、創(chuàng)新”。求真就是勇于探索、追求真理；務實就是崇尚事實、實事求是；無畏就是不畏權(quán)威、不避艱險；創(chuàng)新就是繼往開來、推陳出新。這四個詞組是互為因果的：求真——科學精神的核心，務實——科學精神的基礎，無畏——科學精神的前提，創(chuàng)新——科學精神的目的?？茖W精神是人類賴以生存和發(fā)展的一種精神。

總之，科學是艱巨的、誠實的勞動，它啟迪人們的智慧，培養(yǎng)人們的艱苦奮斗精神和求實精神；科學是探索未來、創(chuàng)造未來的，它培養(yǎng)人們宏偉的胸襟，寬闊的眼界，探索的勇氣和創(chuàng)新的膽識；科學是同謬誤做斗爭中發(fā)展起來的，它培養(yǎng)人們不畏艱險、不怕挫折、鍥而不舍，勇往直前地追求真理和捍衛(wèi)真理的大無畏

勇氣；科學是人類共同的財富，它同一切投機取巧、唯利是圖、自私自利的行徑格格不入，它陶冶人們高尚的情操，培養(yǎng)人們的獻身精神。

看吧！一本知識讀物給我們帶來了多么大的益處，在這個講究科學的時代，如果我們不多學習一些有關(guān)科學的知識的話，我們肯定會被這個時代所漸漸的遺忘，我們只會漸漸的落后，選擇一本好的科普類讀物吧，相信它會給你帶來意外的收獲！

我讀了一本叫《學生探索百科》的書，共分為三章——自然探索、科學探索和歷史探索。這些都對我們的知識了解很有幫祝 地外文明真的存在嗎？動物為什么要冬眠？哥德巴-赫猜想是什么回事？我們能不能跨越時空？這些問題一直伴隨著我，為了解開這些我不懂的“迷”我選擇了《學生探索百科全書》，我希望它可以給我?guī)磉@些問題的答案。

首先我在第一章的自然探索中，我了解了來自宇宙深處的信息、漫長的生命之旅。在第二章的科學探索中，我了解了無處不在的黃金分割、四色之迷、尋找“幽靈粒子”……，這些知識又是我了解到了科學，學會了科學的方法，科學的理論，科學的發(fā)展，科學的分析這些重要的東西，并且在日常生活中遇到的一些奇聞異事我也可以通過科學說法來解答他，這些知識都豐富了我的生活經(jīng)驗，讓我不斷的健康成長。在第三章的歷史探索中，我了解到了絲綢之路、奧林匹克運動會的起源、埃及艷后……歷史使人明智，因為了解歷史，可以學習前人的正確做法，并且改到自己的錯誤作風，這樣可以使人們在成功的路上少一些坎坷，為自己鑄造一條平平的道路。

看吧？對我們的知識了解很有幫住吧。

我讀了《航空到航天》這本書后，懂得了一些關(guān)于飛機的知識，就讓我給你們介紹一下吧！

很久很久以前，人們就夢想像鳥兒一樣在天空中飛。有人嘗試過用羽毛編織成大翅膀綁在身上去天空中飛翔，可是都失敗了。1903年12月17日，由萊特兄弟研制的“飛行者1號”在美國北部卡羅納州德基蒂霍克飛上藍天，從此實現(xiàn)了人類千百年來向往飛行的愿望。

讀了這本書后，我非常欽佩萊特兄弟。他們只有初中文化，但他們刻苦閱讀了許多航空科技書籍，立志要以腳踏實地的科學態(tài)度和百折不撓的實干精神，去揭示人類飛向空中的奧妙。

在學習上，我要以他們?yōu)榘駱樱袼麄円粯佑袆俨或?，敗不餒的精神和堅韌的決心！昨天，我讀了一個故事叫《田忌賽馬》，這故事讓我深受啟發(fā)。

這故事講的是齊國有個人叫田忌，他很喜歡賽馬。一次他約齊王賽馬。每人都準備三匹馬，每次田忌都用同等的馬跟齊王的賽跑，結(jié)果每次都輸了。后來他的朋友出了個點子，他改變了出馬的順序，后來取得了勝利。

這故事告訴我們，只要變換一種思維方式，結(jié)果是相反的。在我們生活中，不也出現(xiàn)許多類似這樣的事嗎？

記得小時候，媽媽出了一道數(shù)學題考我：一個正方形四個角，剪去一個角還剩幾個角？我不回思索地大聲說：“太簡單了，還剩三個角?！苯又鴭寢屇贸鲆粡堥L方形的紙親自讓我動手剪。我拿起剪刀一剪，咦？怎么變五個角了呢？我趕緊改變答案是5個。但我也覺得很奇怪，為什么不是3個？媽媽笑了笑說：“還不完全對，還有一個答案是4個呢?！蔽也煌５脑囍诩埳霞簦€真的有三種可能。這事讓我感受到做什么事都要開動腦筋，換個思維方式做題，就會得到正確的答案。

十二星座失眠原因趣解

在床上翻來覆去、輾轉(zhuǎn)反側(cè)，就是睡不著，這種失眠滋味相信不少人都嘗過。影響睡眠質(zhì)量的因素有很多，如壓力過大，不規(guī)律的作息時間以及心理情緒起伏。我們來看看十二星座的失眠原因都有什么不同吧！

Aries considers sleep too easy and makes a dare with themselves to stay up all night.白羊座：把睡覺看做是件再容易不過的事，想嘗嘗通宵不睡的滋味。

Taurus forgot to pick up their silk sheets at the dry cleaner.金牛座：忘了把絲制床單拿去干洗店清洗。

Gemini's twin just isn't tired.雙子座：失眠的唯一原因就是根本不累。

Cancer worries how everyone else is sleeping.巨蟹座：琢磨為啥其它人都睡著了。

Leo is afraid to move around at all, fearful of what bedhead can do to their lovely mane.獅子座：害怕有人在你床邊來回晃悠，也擔心床頭可能傷到你可愛的“鬃毛”。

Virgo keeps getting up to re-tuck the sheets and fluff the pillows.處女座：不停地起身整理床單和枕頭是失眠的最大原因。

Libra can't quite decide what to wear tomorrow.天秤座：哎，你還沒想好明天該穿什么呢，怎么能睡得著呢？

Scorpio is doing something else entirely.天蝎座：你要能失眠，估計該另當別論了。

Sagittarius can't stop thinking of all the better things they could be doing other than sleeping.射手座：滿腦子里盡想著如果不睡覺可以做哪些好玩的事。

Capricorn already took a strategically planned power nap.摩羯座：善于計劃的你，通常在白天就不時小憩一下，這樣一來，晚上當然睡不香了。

Aquarius suffers from a chat room addiction that keeps them up until all hours.水瓶座：通宵聊天，半夜三更才肯爬上床，不失眠才怪呢。

Pisces has fitful dreams of past lives.雙魚座：可憐的魚兒做夢的時間太長了，影響了睡眠質(zhì)量。

研究：太快樂的人容易早死

新研究稱，太快樂的人比悲觀的同齡人死得早。

People who are too happy die younger than their more downbeat peers, claims

new research.A study which followed children from the 1920s to old age showed that people who were rated 'highly cheerful' by teachers at

school died younger than their more reserved classmates.This was because people who were too happy were more likely to suffer from mental disorders such as bipolar, makingthem less fearful and more likely to take

risks that increase the chance of having a fatal accident.一項跟蹤調(diào)查20世紀20年代的小孩的研究顯示，那些在學校被老師評價為“非常開朗”的人比其他較內(nèi)向的同學死得更早。

這是因為太快樂的人更可能遭受兩極情感障礙等精神疾病的困擾，他們比較不容易恐懼或擔心，更愛去冒險，因而發(fā)生致命意外事故的幾率也增加了。

一個人如果表現(xiàn)得太開心——特別是在不合時宜的時候——還會激怒他人，從而增加被傷害的風險。

來自世界范圍內(nèi)多所大學的研究人員還發(fā)現(xiàn)，通常情況下，一個人如果過于努力地想使自己快樂起來，結(jié)果反而會感覺更郁悶。因為努力改善情緒的結(jié)果經(jīng)常會讓人有受騙的感覺。

研究人員還認為那些介紹如何讓人快樂的雜志文章也會讓人更加抑郁。

一項研究讓參與者閱讀一篇關(guān)于如何改善情緒，然后讓他們遵從其中一條建議，看這種建議的效果如何。

于是參與者采納了文中的建議，比如去看一場歡快的電影，結(jié)果參與者往往過于集中注意力去改善情緒，而不是讓自己的心情自然地好起來。

這意味著，在電影結(jié)束時，他們大多會因聽取建議而感到憤怒，而且會有受騙的感覺。這讓他們的心情比看電影前更糟了。

然而，這一發(fā)表在《心理科學展望》雜志上的研究揭示，通往真正幸福的秘訣要簡單得多：就是和朋友、家人建立深厚的關(guān)系。

該研究報告的作者之一朱恩?格魯伯告訴那些努力想使自己快樂起來的人說：“當

Being too cheerfulcan also rouse angerin others, increasing the risk of a person coming to harm.Researchers from a variety of universities worldwide also discovered that trying too hard to be happy often ended up leaving

people feeling more depressed than before, as putting an effort into improving their mood often left people feeling cheated.And magazine articles offering tips on how

to be happy were also blamed for worsening depression.One study saw participants asked to read an article offering ways to improve yourmood, and follow one of the tips to see

how effective it was.Participants then took the advice offeredoften

concentrated too hard on trying to improve their mood rather than letting it lift naturally.This meant that by the time the film had ended, they often felt angry and cheated

by the advice given, putting them in a far worse mood than when they had started watching.However, results of the study, published in the journal Perspectives on Psychological Science, revealed that the key to truehappiness was much more simple:

meaningful relationships with friends and family members.Study co-author Professor June Gruber,from the department of psychology at Yale

你期待你所做的事讓自己快樂起來時，結(jié)果會讓你失望，并讓你更不開心?！备耵敳敲绹敶髮W心理學系的教授。

“決定幸福與否最有力的因素不是金錢，也不是成功或名氣帶來的外界的認可。獲得幸福的關(guān)鍵是擁有有意義的社會關(guān)系。”

她說道：“這意味著讓自己更快樂的最佳方法就是不再為是否快樂而煩惱，轉(zhuǎn)而將精力投入到增強和他人的社會紐帶上?！?/p>

University in the United States, said of people who actively tried to be happy:

'When you're doing it with the motivation or expectation that these things ought to make you happy, that can lead to

disappointment and decreased happiness.'The strongest predictor of happiness is not money, or external recognition through success or fame.It's having meaningful social relationships.' She added: 'That means the best way to increase your happiness is to stop

worrying about being happy and instead divert your energy to nurturing the social bonds you have with other people

第四篇：雅思寫作科技類[范文]

題目：Scientific and technological advances have changed our lives.But some scientists in some fields say that scientists are not able to find solutions to the problems they have created.To what extent do you agree or disagree?

范文：We sure live differently from our parents did decades ago.The changes are wide and profound.At the same time, we are facing challenges and problems unknown in the past.Could we find solutions to problems created by scientific development? The answer seems to be no.Some of the most obvious problems caused by technological advances lie in the IT industry.At a time when we did not have computers and electronic bank services, people took money with them and paid by cash.If they were stolen, only the amount they had with them was lost.But now credit cards are more commonly used in shopping malls and other places, crimes again us have become more serious and caused greater losses to people.A thief may tape the code of your credit card and make a copy of it.Then he could safely withdraw all your money from an ATM machine.Crimes such as this are very sticky to solve because there is no witness and the surveillance cameras give little help to the police.Another example is the issue of information control with the media industry including TV networks and Internet that give easy access to information without discrimination to people’s age.This has created a huge problem for parents and schools because teenage people are particularly vulnerable to adult materials and information violent in nature.In the past, when most information came in the form of print, it was relatively easy to control what children read.When a parent put away a book unsuitable for children, they were cut off from the source of information.With computer parents could use software to filter bad web sites but could not prevent new ones from appearing every day.People are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful.Even with the little progress we have achieved, we find ourselves defeated by new problems with greater complexity and in wider scope.In conclusion, developments in many fields of our life have brought us both benefits and problems.Developments in the banking industry give us greater convenience but making us targets of computer-based theft.Changes in media industry expose young people to inappropriate information difficult for parent’s control.However up until now, we have not successfully found permanent solutions yet.Mobile(cell)phones and the Internet play an important role in the way in whichpeople relate to one another socially.Is this a positive or negative development? What is your opinion? Give reasons for your answer and include any relevant examples from your own knowledge or experience.Now that you are benefitting from the use of the mobile phone and the Internetas social media as well as social interaction, could you imagine what your daily liveswould be like without these inventions ? Living in this age of information technology may be a blessing, but there seems an undesirable feeling under disguise.For that matter, probably what you like would be social connectivity and what you dislike might be personal anxiety.It is a positive development that people have found it so easy to relate to one another electronically and share instantly in the social context.As technology has advanced, so has the need to remain contact with friends, family and loved ones.Through digital networking, the cell phone and the Internet have opened doors to the current generation's lives, as previously unheard of.While it goes without saying themany benefits that the Internet has to offer, the latest hand phones are well-equipped with high end features catering to a variety of communication needs from voice calls to text messaging.Apart from being able to help connect people anywhere andanytime, new handsets of innovative technology boast cutting-edge functions designed to upgrade work performance and provide fun factors, all at your fingertips.Besides, what do you have to say about Facebook, Twitter and Google+ that are out there on your computer screens or on your smart phones?

Nevertheless, the heavy use in social networking of the mobile phone and the Internet causes anxiety, not to mention the negative effects produced by possible radiation.Chances are that these gadgets are getting you on nerves.It is not so much because of such networking devices keeping you on alert 24/7 as because of the thought of being without them sometimes.So, there are feelings of increased anxiety during the absence of social mobility, as if when you were psychologically alone in the middle of nowhere.And yet, once people being connected, it appears to be no end of interactive communication, particularly when driving, for instance.In this case, the epidemic of people using cell phones to talk and to send text messages via the Internet behind the wheel could give rise to more of a hazard than drunk driving.As long as social interaction is concerned, it may be said that the hi-tech mobility is like a useful gift from heaven rather than a psychological disease from hell.The benefits of social interaction through the cellular and the Wi-fi seem indeed too good to be blamed.Whatever, there is no turning back to the age of B.C.(BeforeComputer).

第一篇

題目132：Some people believe that our ever-increasing use of technology significantly reduces our opportunities for human interaction.Other people believe that technology provides us with new and better ways to communicate and connect with one another.Write a response in which you discuss which view more closely aligns with your own position and explain your reasoning for the position you take.In developing and supporting your position, you should address both of the views presented.There are two different attitudes toward current technology,one comes to that our opportunities of communication have been decreasing by technology while the other holds that it provides us with new and better ways to interact.I have an agreement with the former.Granted that it is a shortened distance that we have with new technology,it does reduce our opportunities for the truly communication and knowing for real lives our friends have.Firstly,we have to realize positive sides of the development of technology.With the overwhelming spread of computer and cellphone in the world,it is significantly convenient for us to keep in touch with friends or family.We are enjoying the facilitation equipped with the high technology on the planet where are becoming more and more smaller taken for us.Secondly,it is no longer being a state of intense anguish for people who are far away from their hometown since cellphone gives them a chance to communicate with family and we can not imagine that previously.In terms of that reason,we have a new way to connect with others.However,does it provide a better way for communication?As we all know that we have less face-to-face communication in the meanwhile getting convenience.As a consequence,we cannot acquire the comprehensive information for lacking eyeball-to-eyeball conversation.As it does in the case of social network.People can update their mode and tell their friends what happens in a day.Nonetheless,for a nature of honour and disgrace,people hardly disclose everything and often select beauty and things that worth to show off.Never learn people by browsing their personal home page.The technology can not tell you the whole real lives of our friends.If you really want to know someone,you have to pay a visit,talk,laugh and share happiness and sorrow.In sum,technology shorten our distance for communication while it never meant to learn a comprehension of our relatives and friends by a technological communication.
