问题     An unidentified wit once said, "Laugh, and the world laughs with you. Snore, and you sleep alone." Yet snoring is far from a laughing matter, as those unfortunates with good hearing, who are rightly【C1】______to the sounds of the snoring disorder, will testify.
    It has been estimated that one of eight Americans snores; this means that there are approximately 21 million people — women as well as men — who render an【C2】______sound when they are asleep. And assuming that each snorer disturbs the sleep of at least one other person, it【C3】______follows that there are 21 million unhappy listeners.
    While a sleeping person breathes, either in or out, several structures in his nose and throat【C4】______the snoring. The sounds, coming from the soft palate(腭)and other soft structures of the throat, are caused by vibratory responses to inflowing and outflowing air. When the soft tissues of the mouth and throat come close to the lining of the throat, the vibrations(振动的)that occur are caused by the position of the tongue. In short, the noise made by snoring can be【C5】______to the noise when breezes flutter a flag on a pole. The【C6】______of the vibrations depends on the size,【C7】______and elasticity of the affected tissues and on the【C8】______of the air flow.
    Although it is usually the process of inhaling or exhaling through the mouth that cause snoring, short snores come from the nose of an open-mouthed sleeper. In all fairness to snorers, however, it should be emphasized that snoring is an【C9】______act which stops as the offender is【C10】______.
A)involuntary I)incur
B)density J)compared
C)necessarily K)sequence
D)unpleasant L)frequency
E)force M)speed
F)unexpected N)generally
G)subjected O)generate
H)awakened
【C9】
选项
答案A
解析 空前不定冠词an及空后名词提示所填词应为以元音音素开头的形容词或名词。第2段第3句话(while a sleeping person breatlles，．．．)讲鼾声是如何产生的，由该句话可知鼾声产生的前提是人要睡着，故可推断人在睡眠中打鼾是他本人意识不到的，所以鼾声是一种无意识的行为，答案为A)involuntary(无意的，不知不觉的)。
