问题     Did you sleep well last night? Or did you wake up feeling fatigued and sluggish — perhaps even wondering if you really slept at all? Getting a good night’s sleep requires more than crawling into bed and closing your eyes.Understanding your sleep behavior and preparing for a sound slumber can help make sure every night is a good night for sleeping.
    "Sleep is a behavior and, like all behaviors, it varies greatly among people," explains Dr. Carol Landis, sleep researcher and associate professor in biobehavioral nursing and health systems at the University of Washington School of Nursing. "The greatest differences occur in the timing of sleep and the amount of sleep — the factors which are most important in determining whether you will wake up feeling rested."
    Research has found that people sleep better at different times during their daily cycle. For example, some people function better if they go to sleep early and rise early, while others feel more rested if they stay up late and sleep in. "Many people don’t pay attention to the timing of their sleep," Landis notes. "Yet delaying or altering the time you go to sleep can have a major impact on how you feel when you wake up."
    The amount of sleep the average adult needs each night also varies. Some people may be fine with six hours sleep, while others need up to nine hours per night. Landis points out that those who follow a regular sleep schedule are more apt to function better on fewer hours, but she adds that most adults need at least six hours of sleep each night.
    "A person’s sleeping patterns aren’t set in concrete," Landis stresses. Gradually altering the timing of sleep can help change sleep patterns. An "evening person" who needs to get to work early in the morning can try upping the time they go to bed by 30 minutes every few days. Within a few weeks, this slow adjustment will help "reset" the internal body clock.
    In addition to maintaining a regular daily sleep schedule, Landis offers the following tips on practicing good sleep hygiene:
    1) Avoid stimulants including cigarettes, caffeinated beverages and food such as chocolate in the late afternoon and evening.
    2) Finish exercising at least two hours before going to sleep. Exercise increases body temperatures and has an arousing effect, making it more difficult to easily fall asleep.
    3) Don’t sleep in a warm environment. A drop in a person’s body temperature is important at the onset of deep sleep. People who sleep in a well-heated room or use an electric blanket may not sleep as soundly.
Which of the following can be a proper title for this passage?
选项 A、Amount of Sleep and Its Effects
B、How to Get a Good Sleep
C、Time of Sleep and Its Effects
D、Dreams and Sleep
答案B
解析 主旨题。选择一篇文章的题目，就必须了解文章的大意，通读全文后可以发现，选项A仅仅提到第四段的内容，选项C是第三、五段的概括，选项D没有出现在原文中，排除法可得B正确。此外，从文末给出的建议也可以推出“如何获得好的睡眠”是更贴切的题目。
