Scientists have learned a great deal in the last thirty years by studying people as they sleep. They study the bodily characteristics that change during sleep. They have learned that there is one kind of sleep which causes rapid eye movement ( REM ) and another kind with no rapid eye movement (NREM).
Sleep is divided into three stages. In stage one, when you start to go to sleep, you have a pleasant floating feeling. In stage two, you sleep more deeply, and a noise will probably not wake you up. In stage three, the brain waves are less active. This third stage is when you dream, REM tends to signal that we are dreaming. For the rest of the night, you alternate between REM and NREM sleep.
Sleep is a biological need, but your brain never really sleeps. The things that are on your mind during the day are still there at night. They appear as dreams. Researchers say that normal people may have four or five REM periods of dreaming each night. The first one may begin only a half hour after they fall asleep, and the final one may last up to an hour. Nightmares (a frightening dream) usually happen toward the early morning.
Besides dreaming, snoring is also common in one's sleep. People snore because they have trouble breathing while they are asleep. Some snorers have a condition called apnea. They stop breathing up to thirty or forty times an hour because the
What should you do if you have trouble sleeping? Lots of people take sleeping pills, but these are dangerous because they can be addictive. Doctors say the best thing is to try to relax and to avoid bad habits.

以下是这些报道的简要内容介绍，请配对它们的标题。
【1】Where did this most popular day for couples come from? And how does it come into beings, year after year? Noel Lenski, professor of the University of Colorado, said the lovers’ holiday traces its roots to raucous annual Roman festivals held every year on February 15 and remained wildly popular well into the fifth century A.D.
【2】The first Earth Day in 1970 was a raucous, radical teach-in that helped spur clean-air, clean-water, and endangered species legislation in the United States. Now, 40 years later, Earth Day is every day, as the saying goes. The thing is, it’s also everyday- environmentalism that has become a routine with greenness as much a marketing tactic as a moral pursuit.
【3】 Some 242 million turkeys were raised in the U.S. in 2010 for slaughter, according to the U.S. Department of Agriculture’s National Agricultural Statistics Service. Last year’s birds were worth about U.S. $3.6 billion. Before the big dinner, debunk the myths, we need to know that the first “real” U.S. Thanksgiving wasn’t until the 1800s and get to the roots of Thanksgiving 2010.
【4】Father’s Day traditionally takes a backseat to Mother’s Day, and, for the most part, dads are cool with that, experts say. Nevertheless, as traditional roles around the house gradually change, fathers are gaining more attention on their special day, at least as measured in the monetary value of gifts estimated to be given on June 19, 2011, when the holiday will be celebrated in dozens of countries.
【5】Cookouts, fireworks, and, of course, a chance to wish Uncle Sam a big “happy birthday” —the day means summer in full swing across the United States and beyond. Besides the founders of the US, Fireworks, first authorized by Congress in 1777, are another legacy. More than 14,000 fireworks displays light up U.S. skies each year.
