CNN News:在陽光中開始新的一天

AZUZ: Up next today, in the U.S., a lot of people are talking about getting an extra hour of sleep this weekend. We fall back, meaning we turn our clocks back one hour on Saturday night. This could help kids catch up on sleep after a busy night of hallowed trick or treating, but also means there`s very little daylight left after the school or workday is over.

阿祖茲：下一則新聞，現(xiàn)在在美國，很多人在談?wù)撚诒局苣┒嗨粋€小時。我們后退，這意味在周六晚上我們將鐘表調(diào)慢一小時。這能幫助孩子們在萬圣節(jié)晚上不給糖就搗蛋繁忙的一晚上后，補覺。但這也同樣意味著在放學或下班之余，本天剩余的時間比較短。

Why do we do this?

我們?yōu)槭裁匆@樣做呢?

AZUZ : Daylight Savings Time sounds kind of special. You`re not just saving time, you`re saving daylight time.

阿祖茲：節(jié)約白天的時間聽起來很特別。你不僅僅是在節(jié)約時間，你是在節(jié)約白天的時間。

But it puzzles the daylights out of some folks why we fall back to standard time.

這就是我們?yōu)槭裁匆芈涞綐藴蕰r間的原因。

That`s what it`s called -- Standard Time.

這就是所謂的——標準時間。

We spend eight months out of the year in daylight saving time, but standard, which is hardly the standard, is still called standard.

一年當中我們花費8個月白天的時間來節(jié)約時間，但是標準時間，幾乎不算是標準時間，仍被稱作標準時間。

It`s been shrinking since World War I. That`s when Daylight Saving Time was first implemented to save energy.

自從第一次世界大戰(zhàn)后，該標準時間一直在減少。那時候，日光節(jié)約時間首次被提出以節(jié)約能源。

The switch made the sunset time, later in the day so people didn`t have to turn their lights on as early.

這個開關(guān)就讓白天日落的時間變晚，所以人們就不會那么早去打開電燈。

But what about winter, and the fall back to Standard?

但是冬天怎么辦呢?退回標準時間之后應(yīng)該怎么辦呢?

Well, look at it this way. Most parts of the U.S. only get about 9 1/2 hours of daylight in winter time.

我們從這方面出發(fā)來看待這個問題。在冬天時，大多數(shù)的美國人僅能利用日光的9.5小時。

That`s not much. If we didn`t set our clocks back in the fall, sunrise wouldn`t be until 8:30 a.m. in many places -- you`d be starting and ending your day in the dark.

這并不多。如果我們在秋天的時候，不將鐘表時間滯后，很多地方在8點半的時候，就不會有日出——可能你一天開始和結(jié)束都在黑暗之中了。

Falling back to standard keeps the time of dawn a little closer to what we`re used to, and it helps us start our day in the light.

回落到標準時間會讓我們的黎明接近于過去的時候，這能讓我們在陽光中開始新的一天。

Plus, there`s that whole extra hour of sleep thing, assuming you go to bed on time when we fall back.

此外，假設(shè)當時間回落到標準時間，我們就可以多睡一個小時。

So, less daylight, but more sleep -- unless you happen to live in Arizona or Hawaii. Most parts of Arizona and all of Hawaii don`t observe Daylight Saving Time. They don`t have to. It`s not required by law.

所以，節(jié)約日光時間，增加睡眠時間——除非你不巧正好居住在亞利桑那州或者夏威夷。在亞利桑那州部分地區(qū)以及夏威夷所有地區(qū)都不用遵守日光節(jié)約時間。他們沒有必要遵守。因為法律沒有規(guī)定。
