CNN News:在阳光中开始新的一天

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.

阿祖兹：下一则新闻，现在在美国，很多人在谈论于本周末多睡一个小时。我们后退，这意味在周六晚上我们将钟表调慢一小时。这能帮助孩子们在万圣节晚上不给糖就捣蛋繁忙的一晚上后，补觉。但这也同样意味着在放学或下班之余，本天剩余的时间比较短。

Why do we do this?

我们为什么要这样做呢?

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

阿祖兹：节约白天的时间听起来很特别。你不仅仅是在节约时间，你是在节约白天的时间。

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

这就是我们为什么要回落到标准时间的原因。

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

这就是所谓的——标准时间。

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

一年当中我们花费8个月白天的时间来节约时间，但是标准时间，几乎不算是标准时间，仍被称作标准时间。

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

自从第一次世界大战后，该标准时间一直在减少。那时候，日光节约时间首次被提出以节约能源。

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

这个开关就让白天日落的时间变晚，所以人们就不会那么早去打开电灯。

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

但是冬天怎么办呢?退回标准时间之后应该怎么办呢?

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

我们从这方面出发来看待这个问题。在冬天时，大多数的美国人仅能利用日光的9.5小时。

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.

这并不多。如果我们在秋天的时候，不将钟表时间滞后，很多地方在8点半的时候，就不会有日出——可能你一天开始和结束都在黑暗之中了。

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.

回落到标准时间会让我们的黎明接近于过去的时候，这能让我们在阳光中开始新的一天。

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

此外，假设当时间回落到标准时间，我们就可以多睡一个小时。

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，节约日光时间，增加睡眠时间——除非你不巧正好居住在亚利桑那州或者夏威夷。在亚利桑那州部分地区以及夏威夷所有地区都不用遵守日光节约时间。他们没有必要遵守。因为法律没有规定。
