[不定项选择题]共用题干 Owls and Larks（猫头鹰与云雀）

1 In this article,we look at the importance of sleep for learning. Most healthy adults need eight or more
hours of sleep.But why do we need sleep in the first place?We need sleep for the brain to get a chance to
rebuild memories stored during the day and associate these with previously learned things.If this process is
interrupted by,say,the sound of an alarm clock,it may not be as effective.So if your sleep is cut short by the
alarm clock,how damaging is it?The truth is that it's difficult to predict,as so much depends on how much
sleep your body actually needs on that particular occasion.
2 The popular belief that people are naturally either larks(early risers)or owls is false.The reason
why people tend to be one or the other has more to do with lifestyle,age,and personality.Many people who
appear to be early birds may have just become so through habit,for example,parents with very young chil-
dren.Teenagers can have difficulty falling asleep until late at night and then they naturally have problems
getting up the following morning.
3 The main reason why owls are owls is that they tend to spend their time over a book,movie,or corn-
puter game till the early hours of the morning.They enjoy the quiet of the night when they can pursue their
passion.On the other hand,larks can make better use of early morning hours where they can study in quiet at
the time when their brains are most refreshed.So which is better for learning一an owl's or a lark's lifestyle?
The simple truth is that it is more complex than simply being one or the other. Leading a well-balanced life in
terms of work and play and sleeping enough to bring maximum refreshment is probably the secret.
4 As for naps , experts on insomnia（失眠）argue against taking naps , as these may keep people up at
night. If your nap lasts only five minutes to haff an hour and does not affect your ability to fall asleep in the
night,it will probably help you be more alert in evening hours.However,if you are having problems getting to
sleep at night , it's not only naps that you should avoid. Try not to drink a lot of alcohol , take nicotine（尼古
丁）,do mentally intense activities like preparing for exams or doing exercise in the evening. Some people
swear that drinking coffee never stops them from sleeping like a log,whereas others will never go near the
stuff for fear of being awake all night.However,the best advice for most is to avoid it in the evening,and if
you drink coffee before a nap,remember you are likely to awaken as soon as the caffeine starts kicking in. Paragraph 3________

The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We ail enjoy our freedom of choice and don’t like to see it restricted. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we eau smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary lifestyle without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.A. current medical knowledge is still insufficient
B. there are many factors influencing our decisions
C. few people are willing to trade the quality of life for the quantity of life
D. people are usually influenced by the behavior of their friends
