[单项选择]After decades of exile from U.S. courts, the science of lie detection is gaining new acceptance. But the federal government wants to put a stop to it, and the U.S. Supreme Court has now agreed to consider a request from the Department of Justice to bar the technology from military courts.
Uncertainties surround the science of lie detection, which uses a device called polygraph. In 1991 President George Bush banned lie detector evidence in military courts. But that ban has since been overturned by the U.S. Court of Military Appeals, which ruled that it restricts defendants’ rights to present evidence of their innocence.
In the past two years, some federal courts have also ruled that polygraph evidence can be heard. This follows a decision by the Supreme Court in 1993 that gave federal judges more discretion to decide on the admissibility of evidence.

[单项选择]Every living thing has an inner biological clock that controls behavior. The clock works all the time even when there are no outside signs to mark the passing of time. The biological clock tells plants when to form flowers and when the flowers should open. It tells insects when to leave the protective cocoon and fly away. And it tells animals when to eat, sleep and wake. It controls body temperature, the release of some hormones and even dreams. These natural daily events are circadian rhythms.
Man has known about them for thousands of years. But the first scientific observation of circadian rhythms was not made until 1729. In that year French astronomer, Jean-Jacques d’Ortous de Mairan, noted that one of his plants opened its leaves at the same time every morning, and closed them at the same time every night. The plant did this even when he kept it in a dark place all the time. Later scientists wondered about circadian rhythms in humans. They learned that man’s biological clock a

[填空题]Sleep
Sleep is part of a person’s daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber, your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing will slow and become quite regular. Your brain waves slow and become quite regular. That is stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then about 40 to 69 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain will show the large slow waves that axe known as the delta rhythm. This is stage 4 sleep.
You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity leve
