      【第1篇】

      【風趣的貨幣】

      下面我來給大師講一個相關“匯率問題”的糊口小故事。

      今天,我的一個好伴侶從韓國玩耍回來,她驚訝地告訴我,日常平凡我們需要15元人平易近幣的一碗通俗面條,正在韓國竟然要2700多韓元的“天價”,那吃一頓飯得要幾多韓元?莫非韓國人都是“大財主”!可是,正在經濟實力十分強大的美國,一碗同樣的面卻只需大要2美元,這是為什么呢?經濟實力強的國度反而工具廉價,莫非美國人反而比韓國人窮嗎?本來正在廚房洗碗的媽媽聽見了,笑著走出來對我們說:“其實適才你們談的就是匯率問題。”“什么是匯率問題?”我們有些丈二摸不著思維。媽媽擦拭掉手上的水珠拿出手機調出匯率查詢并說道;“匯率其實就是兩種貨泉之間兌換的比率,也就是一個國度的貨泉對另一個國度貨泉的價值。”“哦~”我們似懂非懂的點點頭。“舉個例子吧”媽媽拿出手機調出匯率查詢接著說道:“一件價值100元人平易近幣的商品,這時人平易近幣取美元的匯率是1比0.1502,那這件商品正在美國的標價就是15.02美元。若是人平易近幣對美元的匯率調整為1比0.1429,也就是說美元升值某人平易近幣貶值。那這件商品此時的價錢就是14.29美元,如許就能夠用更少的美元買到這件商品了。這時這件商品正在市場上的價錢變低,市場所作力就變高了,工具廉價了就會賣良多。相反,美元貶值某人平易近幣升值,此時該商品的價錢就變貴了,要采辦的人就會相對削減。這就是匯率變化的奇奧之處。你們看人平易近幣取韓元的匯率是1比189.2665,那我們這15元一碗的面,正在韓國當然要2700多韓元啦。”

       “哦,本來是如許啊,怪不得韓國的面那么貴呢!哈哈!”沒想到日常平凡不起眼的錢還有這么多學問,我們的世界還實是奇奧呢。

      【第2篇】

      奇異的數字

      那天,我很無聊。我就正在電腦上亂搜。無意間,我發覺了“142857”這個奇異的數字。我發覺了它那奇異的變變:142857×1等于142857,142857×2等于258714,13857×3等于428571,142857×4等于571428,13857×5等于714825,142857×6等于857142。這六組數字竟然是由142857沉組后得出的。再把它乘7我們會驚訝的發覺是999999。我十分的驚訝,我繼續往下看,成果讓我匪夷所思。這個數最早發覺于內的奇奧數字。把142857分成兩組數字,142,857,正在相加后獲得999。把它分成三組數字,14,28,57,再把它們相加起來獲得99。最初,142857×142857等于。正在把他們分成20408和122449,再把它們的相加等于142857。142857它發覺于埃及內,是一組奇異的數字,證明一禮拜有七天。它累加一次,就由它的六個數,違拗序輪值一次。到了第七天,它們就放假,由999999去代班。數字越加越大,每跨越一禮拜,每個數字需要兼顧一次。

       無數巧合中必有概率無數任何終必有紀律。何為紀律?大天然的規律!科學就是總結現實從中找出紀律。
