英语段落|2021年更加短暂
' Time waits for no man ' — or so the saying goes .We can't stop time and we can't control it , although sometimes , in our minds , we think time flies — for example , when the weekend arrives , we feel it's over in no time! But if this year in particularfeels like it's passing more quickly than others have done , there could be a scientific explanation why . Of course , we know a year is usually 365 days long . Clever scientists calculated this a long time ago. They also worked out that every four years , we need an extra day to keep our calendar in sync— this is called a leap year . But 2021 isn't one of those years , and yet it's not behaving like a normal year . Scientists and astrophysicistshave done the math and discovered the Earth is moving faster than it ever has in the last 50 years . This means that 2021 is going to be the shortest year in decades . Apparently , this is because the Earth is spinning faster on its axis , quicker than it has done in decades , and the days are therefore shorter . But they are only short by a tiny amount — around 0.05 milliseconds — so don't panic if you haven't noticed ! However , long-term these milliseconds add up . Astrophysicist Graham Jones and Konstantin Bikos from Time and Date told The Independent newspaper : “ If the Earth's rotationcontinues to quicken , we may at some point require a negative leap second . If this happens , our clocks would skip a second in order to keep up withthe hurrying Earth .” Since 1972 , 27 leap seconds have only been added to our time and none have been taken away . This really is only of concern for atomic clocks — the most accurate timekeeping devices in history . Studying the Earth's rotation and then subtracting or adding a leap second to these clocks can ensure they remain aligned and keep us on time . But now , maybe we need to get a move onbefore this ' shorter ' year is gone in a split second !
俗话说,光阴不等人。我们无法让光阴停下来,也无法节制它,只管有时,在我们的脑海中,我们感到光阴过得飞快——例如,当周末到来时,我们感到它很快就停止了。然则,假如本年分外让人感觉它比往年过得更快,那么此中的缘故原由可能有科学解释。当然,我们知道一年通常是 365 天。聪慧的科学家早就计算出了这一点。他们还发现,每四年,我们必要额外的一天来坚持日历的同步,这一年被称为闰年。但2021年不是如许的年份,并且它的表示也不像一个正常的年份。科学家和天体物理学家进行了数学计算,发现地球的活动速率比曩昔五十年来任何时刻都要快。这意味着2021年将是几十年来最短的一年。显然,这是由于地球自转速率比曩昔几十年都要快,是以日间也变短了。但它们只短了一点点——年夜约0.05毫秒——以是假如你没有注意到的话,也不要恐慌。然而,毫秒也会积小成多。来自“天下日期实时间网”的天体物理学家格雷厄姆-琼斯和康斯坦丁-比科斯奉告《自力报》说:“假如地球的自转继续加速,在某一时候我们可能必要一个负闰秒。假如产生这种环境,我们的时钟就会必要削减一秒,以跟上快速转动的地球。”自1972年以来,我们的光阴增长了 27 个闰秒,没有一个闰秒被削减过。这现实上只与汗青上最准确的计时装备——原子钟有关。研讨地球自转,然后在这些时钟上减去或增长一个闰秒,可以确保它们与地球转动坚持同等,让我们的光阴精确。但如今,大概我们必要在这“较短”的一年须臾即逝之前继续前进。
