美国有线新闻 CNN 美国11月1日结束夏令时 时钟要回拨一小时（在线收听）

Which of these events occurs on November 1, 2020? U.S. presidential election, first day of fall, Standard Time switch or space telescope launch? November 1 is when we fall back to Standard Time, setting our clocks back one hour.

下列哪个事件将在2020年11月1日发生？美国总统大选、秋季第一天、标准时间转换还是太空望远镜发射？11月1日是标准时间回调的日子，我们要将时钟回拨一个小时。

Falling back has its supporters. You can get that extra hour of sleep but only if you go to bed on time. As the days get shorter, the switch to Standard Time keeps sunrise a little closer to when we wake up. And Daylight Saving Time, which we're on right now does conserve a bit of electricity.

有人支持回拨时间。你可以多睡一个小时，但前提是你要按时睡觉。随着白天变短，标准时间的切换会使我们起床的时间更接近日出时间。而我们现在使用的夏令时确实省了些电。

But people of the American Academy of Sleep Medicine want to get rid of the time switch. Specifically they want to end Daylight Saving Time which means we'd fall back but never spring forward again. The problem, some experts say, is because it takes our bodies days to adjust to an altered sleep schedule and that a third of Americans don't get enough regular sleep anyway.

但美国睡眠医学会的成员不想进行时间转换。具体来说，他们希望结束夏令时，这意味着我们会将时间回拨一小时，但再也不会拨快一小时。一些专家表示，问题在于，我们的身体需要几天时间来适应改变的睡眠时间表，而且三分之一的美国人睡眠时间不规律。

This reportedly leads to all kinds of health problems. If the time changes stay though, experts say we can ease the transition by gradually adjusting our sleep schedules before falling back or springing forward.

据报道，这会导致各种各样的健康问题。但专家表示，如果继续转换时间，我们可以通过逐步调整睡眠时间表来平稳过渡，然后再将时间回拨或拨快。
