问题     Long time ago, everyone knew that regular bedtimes were important. "Dream on! " most modern parents might reply. But research by Yvonne Kelly of University College, London, shows that the【C1】________wisdom is right-half the time. Daughters, it seems, do【C2】________ regular bedtimes. Sons do not.
    Dr Kelly knew of many studies that had looked at the connection between sleep habits and cognitive ability in adults and【C3】________. All showed that inconsistent sleeping【C4】________went hand in hand【C5】________poor academic performance. Surprisingly,【C6】________little such research had been done on children She【C7】________examined the bedtimes and cognitive abilities of 11,178 children born in Britain.
    She collected the bedtime information of the participants when they were nine months, three years, five years and seven years of age.【C8】________asking whether the children had【C9】________bedtimes on weekdays and if they always, usually, sometimes or never made them, she collected information about family【C10】________ economic circumstances and other matters—including whether children were read to before they went to sleep and whether they had a television in their bedroom. The children【C11】________were also asked, at the ages of three, five and seven, to take standardized reading, mathematical and spatial-awareness tests, from which their IQs could be【C12】________.
    Dr Kelly’s report shows that by the time children had reached the age of seven, not having had a regular bedtime did seem to【C13】________their cognition, even when other relevant【C14】________such as bedtime reading, bedroom televisions and parents’ socioeconomic status were controlled for. But that was true【C15】________if they were female. On the IQ scale, girls who had regular bedtimes【C16】________between eight and nine points more than those who did not.
    Boys were not completely unaffected. Irregular bedtimes left their IQs about six points below those of their【C17】________at the age of three. But the distinction【C18】________by the time they were seven.
    This difference between the sexes is【C19】________Dr Kelly did not expect it and has no explanation to offer for it. As scientists are accustomed to say, but this time with good reason, more research is【C20】________.
【C4】
选项 A、postures
B、schedules
C、modes
D、problems
答案B
解析 上句提到关于睡眠习惯(sleep habits)与认知能力(cognitive ability)之间关系的研究。本句的academic performance与cognitive ability对应，因此所填单词也应和sleep habits有关。B项schedules“时间表”与第一段的bedtime(就寝时间)呼应。A项postures“姿势”，本文讨论的是睡眠时间而非睡姿，语义不符。C项modes“模式”，和sleep搭配意为“休眠模式”，常用于形容电子设备的状态。D项problems“问题，难题”，和inconsistent(不固定的；不一致)搭配后语义不通顺。
