雅思寫作素材：科技類寫作話題

除了寫作真題練習，考生們是否會關注一些身邊日常話題呢?事實上，雅思寫作真題都偏社會話題，這也提醒了很多考生，注意在日常多積累相關的寫作話題素材，并進行深度思考。本期小站雅思君就為大家提供有關科技類寫作話題的素材。

以科技類話題為例：Space exploration like looking for life or resources on other planets is a waste of money, because there are many problems on the earth to solve. Do you agree?

題解與示例：

針對太空探索的正面意義，筆者打算從以下四個方面進行分析：

(一)太空探索與科技發展：

關于太空探索與科技發展的討論是所有爭論中最古老、最核心的一個。(The oldest and purest argument for space exploration is the advancement of science and technology.)那二者的關系如何，太空探索是科技發展的因還是果?其實，兩者是相互促進的。

要想論述好這一問題，首先我們要意識到：航空航天科技是一項綜合性高技術，它依賴于一系列相關高技術的發展。(Astronautical technology is a comprehensive high technology that widely depends on a series of modern techniques: electronic technology, computer science, remote sensing technology, new materials science and engineering, etc.)其次，許多我們日常生活的一些功能服務，如：天氣預報、GDS導航、衛星電視等，都離不開太空基礎設施。(Many common everyday services such as weather forecasting, GPS systems, satellite television, and so on critically rely on space infrastructure.)

綜合以上兩點，航空航天科學技術的重要性可見一斑，事實上，它常被看作是現代化國家綜合國力的一個標志。(Advanced space technology is a symbol that stands for the power of a country.)也正因為如此，太空探索能夠刺激和帶動一系列相關科技產業的發展，因此應當被鼓勵。(Developing space technology in turn helps fuel the development of correlated industries.)

(二)太空探索與現實問題：

我想將太空探索定義為是人類對于未來的一項投資(Space exploration is an investment in the future)，解決現存于地球上的迫切的現實問題是人們對太空探索寄予的最大期望之一。開發太空有希望解決兩大現實問題，一個是地球上資源與能源的匱乏。(With finite resource and exhaustible energy on the earth, there is a growing demand to exploit the outer space for human benefits.)另一是人口不斷膨脹所導致的糧食、耕地、生存空間、環境承載力緊張的問題，探索太空即是尋找人類的第二家園。(As overpopulation is becoming a serious worldwide crisis, we are in desperate need to search for a new planet for crops planting or even making it our home.)

與此同時，對于宇宙的探索也有助于人類更好地了解地球自己，隨著人類知識的增長和眼界的開闊，現在困擾我們的一些現實問題也許在將來就迎刃而解了呢!太空探索有可能為人類解決現實問題提供意想不到的新途徑。(Meanwhile, in the wake of ever-increasing knowledge about the universe as well as the earth, human beings may somehow be able to solve those long-standing problems that seem to have no solution for now.)

(三)太空探索與人類本能：

這是一個相對宏大的哲學視角。太空探索源自根植于人類基因中的好奇心本能和冒險精神。千百萬年以前，我們的祖先迫于生存的需求不斷開拓、遷徙，致使從先前的幾個小部落領地擴張到了如今的占據整個地球表面，也正因為如此我們的種族得以繁衍傳接下去，生生不息、經久不衰;而這樣的擴張還將繼續——人類向宇宙邁進。

(Our wonder and imagination about the outside world have never stopped since we were early hominids. Actually, it is the very human instinct -- curiosity -- that impels people to constantly explore and expand, pushing new frontiers from lands to seas, venturing out from Earth to the universe. The strong need to take risks and expand into new territory is rooted in our genetic make up and essential to our species’ success. Therefore, exploring into the solar system and other worlds of the space is an imperative rather than a luxury, as we’ve already occupied the surface of our planet.)

(四)太空探索與自然科學：

關于“What is science?(什么是科學?)”這一問題，我們中國人的認識也許不太準確。Science一詞源自于拉丁文scientia，即為“knowledge about the world(關于世界的知識)”之含義;科學的誕生是希臘文化的結晶，其目的在于理解世界的本質、探尋永恒不變的真理。它本身是不帶有任何實用主義色彩的。古希臘的先民們熱衷于探討地球是方的還是圓的、地心說和日心說哪個正確……這些問題無一有關于實用主義，而僅出于人天性中對“我們是誰?”、“我們來自何方?”、“我們在宇宙中處于怎樣的位置?”等未知問題的困惑。為了弄清楚這些問題，諸如蘇格拉底、亞里士多德等哲學家們發展了一套邏輯的和實驗的方法，由此誕生了西方的自然科學。而我們東方人對于這種“無用的知識”很不理解，并發明了“杞人憂天”一詞去譏笑這種行為;試想一下，“天究竟會不會塌下來?如果會，我們又該怎么辦?”若放在古希臘文化里會是多么重要的一個課題!再加之，西方科學的傳入正值近代中國落后挨打之時，很自然地，中國人就形成了“科學是第一生產力”的觀念偏誤。

科學應該是非功利的。從這個意義上講，現代的太空探索作為天文科學研究的一種，也應該不問“回報”。

(Who we are, where we come from, these are the questions we have been asking ourselves. In understanding the world where we live, came the birth of modern natural science; in looking for a place where we belong, started a new field of astronomy. Science is never meant to be anything practical or functional, and not every scientific research would seem relevant to our life right at this minute. But it has to go on, because after all, the challenge and conquest of the unknown are the highest ideal of human beings and the eternal drive of all human progress.)
