【答案】
（1）D
（2）A
（3）A
（4）B
（5）C
【解析】【分析】本文论述足够的睡眠在儿童的成长和有效学习中的重要作用。
（1）细节理解。
由文中第三段最后一句话“Evenlosingonehour'
ssleepanightcanmeanthatchildrendolesswellatschool.”可知睡眠不足导致儿童在学校表现不好，故答案为D。
（2）细节理解。
作者在第二段首先提出的问题是“年轻人每天晚上需要多长时间的睡眠”,答案是“8到10个小时”。
故答案为A。
（3）细节理解。
根据第三段的“Thetraditional'
bedtimestory'
helpschildrentorelaxandfallasleeppeacefully.”可知睡前故事能让儿童放松，很平静的入睡，故答案为A。
（4）推理判断。
根据第三段的“ChildrenwithTVsandcomputersintheirbedroomsweremorelikelytosleepbadly,andtogetlessthaneighthours'
sleep.”可知,如果卧室里有电视和电脑,孩子们的睡眠质量就会变差,并且睡眠少于八小时。
由此可以推断,如果房间里没有电视和电脑,孩子们会睡得更好,睡眠的时间更长。
故答案为B。
（5）推理判断。
将题干中的theGermanscientists'
experiment定位在最后一段，根据suggestingtheirbrainshadbeentryingtofindtheanswerwhilethepeoplewereasleep可知大脑在睡眠时运转的更好，故答案为C。
【点评】本文属于议论文，阅读时首先要弄清楚作者要证明什么观点，然后用什么样的论据进行怎样的分析，最后得出了什么样的结论，理清了线索，理解文章就不是问题。
看题时注意确定关键词，然后在文章中定位，找到与选项一致的内容，就可以轻松的确定答案。
