population are occurring in developing countries, which will see a jump of 140 percent by global aging represents a triumph of medical, social, and economic advances over disease, it also presents tremendous aging strains social insurance and pension systems and challenges existing models of social affects economic growth, trade, migration, disease patterns and prevalence, and fundamental assumptions about growing data from the United Nations, Bureau, and Statistical Office of the European Communities as well as regional surveys and scientific journals, the Institute on Aging(NIA), with input from demographers, economists, and experts on aging, identified nine emerging trends in global , these trends present a snapshot of challenges and opportunities that clearly show why population aging matters.● The overall population is the first time in history, and probably the only time in human history, people age 65 and over will outnumber children under age 5.● Life expectancy is countries, including developing countries, show a steady increase in longevity over time, which raises the question of how much further life expectancy will increase.● The number of the oldest people is age 85 and over are now the fastest growing portion of many national populations.● Nonmunicable diseases are being a growing nonmunicable diseases are now the major cause of death among older people in both more developed and less developed countries.● Some populations will shrink in the next few world population is aging at an unprecedented rate, the total population in some countries is simultaneously declining.● Family structures are people live longer and have fewer children, family structures are transformed, leaving older people with fewer options for care.● Patterns of work and retirement are ratios of workers to pensioners and people spending a larger portion of their lives in retirement increasingly strain existing health and pension systems.● Social insurance systems are social insurance expenditures escalate, an increasing number of countries are evaluating the sustainability of these systems.● New economic challenges are aging will have dramatic effects on social entitlement programs, labor supply, trade, and savings around the globe and may demand new fiscal approaches to acmodate a changing governments have begun to plan for the long term, but most have window of opportunity for reform is closing fast as the pace of population aging Europe currently has four people of working age for every older person, it will have only two workers per older person by some countries the share of gross domestic product devoted to social insurance for older people is expected to more than double in uping therefore have only a few years to intensify efforts before demographic effects e to challenges may seem daunting, but a host of opportunities await us as instance, countries that have begun to address issues of population aging can share their are exciting opportunities for economic expansion and crossnational collaboration as well, but we must act now or the costs of waiting—financial and social—will be overwhelming.第五篇：第七單元讀后感第七單元讀后感讀了文章、書籍，把自己的體會(huì)、感想寫下來，就是讀后感。寫讀后感，“讀”是基 礎(chǔ)，要讀懂文章想告訴我們什么；“感”是重點(diǎn)，要著重寫出自己的感受，不宜過多地重 復(fù)作品的內(nèi)容，為了更好地表達(dá)自己的感受，也可以適當(dāng)引用相關(guān)的資料。讓我們就課文或讀過的其他文章寫一篇讀后感。寫好后和同學(xué)交換看一看，交流 一下怎樣才能寫好讀后感。寫法告訴你：一定聽過“讀書破萬卷，下筆如有神”吧！但是，是不是讀書多了，就一定能夠?qū)懞梦恼履兀坑性S多愛讀書的少年朋友，說起書中的故事，他們就會(huì)滔滔不 絕地講個(gè)不停?？墒侨粢崞鹱x書后感受最深的一點(diǎn)，卻東拉西扯，說不到點(diǎn)子上，這 次習(xí)作，我們就要學(xué)習(xí)寫讀后感，老師教大家?guī)渍?，?zhǔn)保有效！讀后感，就是讀了一本書或一篇文章，或讀了一段話或某句名言后，把具體感受和 得到的啟示寫成文章。所謂“感”，可以是從書中領(lǐng)悟出來的道理或精湛的思想，可以 是受書中內(nèi)容啟發(fā)而引起的思考和聯(lián)想，可以是因讀書激發(fā)的決心和理想，也可以是 因讀書而引起的對(duì)社會(huì)上某些丑惡現(xiàn)象的抨擊。讀后感的表達(dá)方式靈活多樣，要寫好 有體驗(yàn)、有見解、有新意的讀后感，必須注意以下幾點(diǎn)：第一，要讀好原文。“讀后感”的“感”是因“讀”而引起的?！白x”是“感”的基礎(chǔ)。走馬觀花地讀，可能連原作講的是什么都沒有掌握，哪能有“感”？讀得膚淺，當(dāng)然也感得不深。只有讀得認(rèn) 真，才能有所感。如果是記敘文，就要弄清它的主要情節(jié)，有幾個(gè)人物，他們之間是什 么關(guān)系，以及故事發(fā)生在哪年哪月，作品涉及的社會(huì)背景，還要弄清作品通過記人敘 事，揭示了人物什么樣的精神品質(zhì)，反映了什么樣的社會(huì)現(xiàn)象，表達(dá)了作者什么樣的思 想情感，作品的哪些章節(jié)使人感動(dòng)，為什么有這樣的感動(dòng)等等。、第二，選準(zhǔn)感動(dòng)點(diǎn)。一篇文章，可以排出許多感動(dòng)點(diǎn)，但在一篇讀后感里只能論述一個(gè)中心，切不可面 西俱到，所以緊接著便是對(duì)這些眾多的感動(dòng)點(diǎn)進(jìn)行篩選、比較，找出自己感受最深、角 度最新、現(xiàn)實(shí)針對(duì)性最強(qiáng)，自己寫來又覺得順暢的一個(gè)感動(dòng)點(diǎn)，作為讀后感的中心，然 后加以論證成文。第三，要處理好“讀”和“感”的關(guān)系?！白x”是“感”的前提，“感”是讀的結(jié)果和目的。我們一般可采用這樣的步驟：先簡 單談?wù)剷蛭恼碌闹饕獌?nèi)容；再具體說說哪些地方寫得好，怎樣好；再聯(lián)系我們的實(shí)際 生活談?wù)勎覀儚闹惺艿绞裁唇逃玫绞裁磫l(fā)，明白了什么道理。在表現(xiàn)手法上，我 們可采用夾敘夾議的方法，以議為主，將自己體會(huì)深的地方寫詳細(xì)、寫具體。感想和體 會(huì)一定要真實(shí)可信，要避免空談和說大話。第四，敘述要簡明、扼要。既然讀后感是由讀產(chǎn)生感，那么在文章里就要敘述引起“感”的那些事實(shí)，有時(shí)還 要敘述自己聯(lián)想到的事例。總之，讀后感中少不了“敘”。但是它不同于記敘文中對(duì)“敘”的要求。記敘文中的“敘”講究具體、形象、生動(dòng)，而讀后感中的“敘”卻講究簡明、扼要，它不要求“感人”，只要求能引出事理。以下習(xí)作素材供你參考：素材1讀了愛因斯坦的故事，我最大的感受是明白了“成功之花，人們只驚異雹 現(xiàn)時(shí)的明艷，卻不知當(dāng)初它的芽，浸透了奮斗的汗水，灑遍了犧牲的血雨”。我對(duì)“勤毹 補(bǔ)拙”有了深刻的體會(huì)。素材2讀完了《鏡子小史，我不光了解了鏡子的發(fā)展歷史及作用，還對(duì)一段翻感觸很深：“鏡子永遠(yuǎn)是那樣忠實(shí)，毫不隱瞞地告訴你，你的臉上有沒有污斑?！比藗兪?生活中也許需要鏡子。素材3我懷著無比崇敬的心情讀了《我的戰(zhàn)友邱少云，對(duì)照邱少云，我羞愧牙 已。回想上課的時(shí)候，老師在上面大講，我在底下小講??如今這篇課文像明燈，閃炳 心頭；像戰(zhàn)鼓，在身畔震撼；像多彩的陽光，伴我踏上前進(jìn)的征程！素材4《未來的房屋》主要介紹了未來房屋的一些設(shè)備。掩卷沉思，我想了許多；從古代猿人住洞穴到現(xiàn)代人住瓦房、樓房，人類在不斷地進(jìn)步著??這些成就靠什 么來創(chuàng)造呢？這就靠科學(xué)知識(shí)。一個(gè)人有了知識(shí)，再加上勤奮的勞動(dòng)和聰明才智，就 可以創(chuàng)造美好的東西。素材5《鄭人買履》是一則寓言故事，它主要講了一個(gè)刻板的鄭國人想去市場(chǎng)買 鞋，便在家里量出鞋的尺碼，最后卻因把量好的尺碼忘在家里，而沒能買成鞋子的故 事。讀完后我明白了一個(gè)道理：凡事要靈活，不可以生搬硬套。
