Ahhh, sleep. There's nothing better than a nice, long, uninterrupted [LOUD NOISE]. Awwgh. I can't sleep when there's [NOISE]. But d'ya ever notice: noise [NOISE] doesn't wake everyone. Now scientists have a better idea why. Because ____1____, findings published in the journal Current Biology.
To study the brain waves of a good night's sleep, scientists invited volunteers to ____2____ in the lab. While the subjects ____3____, the researchers monitored their brain activity. They then subjected the sleepers to [NOISE] or [NOISE]. And they found that those who were able to slumber ____4____ all the [NOISE] showed more short bursts of faster brain waves. This activity, the scientists say, is the brain's way of ____5____ the [NOISE] and the [NOISE] while you're trying to rest.
The scientists don't yet ____6____ boost those sleep-saving brain waves. So until then, shut the door [DOOR SHUTTING], make sure the late show's on a timer [TV SOUND], and try to have sweet dreams.
sound sleepers show a certain brain rhythm when they doze snooze caught some Zs straight through blocking out know of any way to
啊～～～睡覺是多么美妙啊！再沒什么比得上美美地睡一個香甜悠長的好覺了，當然還要不受打擾（巨大的噪音）……呃…………在電閃雷鳴之時（打雷聲）我可睡不著，不過你是否注意到，并不是每個人都會被喧鬧聲（小號聲）吵醒。如今，科學家們對于這一現(xiàn)象有了更好的解釋。根據(jù)《現(xiàn)代生物學》雜志上刊登的研究結(jié)果，這是因為熟睡者在打鼾時會顯示出某種腦波律動。 為了對夜晚好眠時的腦電波進行研究，科學家們請志愿者在實驗室里打盹兒。當他們開始鼾聲連連時，研究人員就監(jiān)測他們的大腦活動，然后再給入眠者制造些噪音（鈴聲、喇叭聲）。他們發(fā)現(xiàn)那些對噪音毫不理會、依舊呼呼大睡的志愿者會顯示出更多更快的短脈沖腦電波?？茖W家們稱，這種腦部活動是人們在休息時大腦屏蔽噪音（摔東西聲、狗吠）的一種方式。 科學家們還不知道有什么方法可以增強那些能夠保證睡眠的腦電波。因此，在有效方法找到之前，關(guān)上房門（關(guān)門聲），確保夜間節(jié)目別看到太晚（電視節(jié)目聲），然后進入甜蜜夢鄉(xiāng)吧。
