【解析】

试题分析：每个人都需要睡眠，充足的睡眠对健康的意义非常重大。为了有一个良好的睡眠，需要考虑诸多因素，如时间，睡觉的场所及睡觉时的温度等。

【1】needed 考查非谓语动词。句意：个人所需的睡眠时间取决于他的年龄及睡觉的环境。分析可知the amount of sleep与need之间为动宾关系，所以用need的过去分词形式作定语修饰the amount of sleep，表示“所需的睡眠时间”。故填needed。

【2】which 考查定语从句。句意：个人所需的睡眠时间取决于他的年龄及睡觉的环境。分析可知介词+which/whom引导定语从句，the conditions为先行词，所以选择which. 定语从句可还原为sleep takes place in the conditions.故填which。

【3】the 考查冠词。句意：年轻人可能比老年人需要更多的睡眠。分析可知the+adj.表示一类人，如the young年轻人；the poor穷人；the old老年人。故填the。

【4】less 考查代词。句意：有些人对睡眠的需求量可能比这个量要少，但有些人可能需要更多。根据后文others may need more可知此处应填“有些人需求量少”，故填less。

【5】but 考查连词。句意：有些人对睡眠的需求量可能比这个量要少，但有些人可能需要更多。根据less than this amount及后文many need more，可知前后文之间为转折关系。故填but。

【6】It 考查代词。句意：满足个人的需要是一个好的判断标准。分析可知it作形式主语，to satisfy his need为真正的主语。故填It。

【7】strength 考查词性。句意：充足的睡眠能够让人恢复精力并为一天的工作做好准备。分析可知此处应填strong的名词形式。strength：力量；长处；强项。故填strength。

【8】without 考查介词。句意：所以有些人认为在空气流通的环境中睡觉是有实际意义的，这并不无道理。without reason：不合情理；无缘无故。句中So it is not without reason for some people to think that it is practicable to sleep in the open air为双重否定表肯定的语气。故填without。

【9】neither 考查连词。句意：睡前一个不冷不热、温度适宜的沐浴可能会对睡眠有所帮助。分析可知neither hot nor cool but of body temperature表示“既不太冷又不太热，与体温适宜的温度。故填neither。

【10】suggested 考查被动语态。句意：除非医生建议，否则不要吃安眠药。分析可知句中出现省略，原句Sleep-producing drug should never be taken except when suggested by a doctor可还原为One should never take sleep-producing drug except when he is suggested by a doctor. 时间状语从句中he和suggest之间为动宾关系，且时间状语从句符合省略原则，所以将主语he和be动词is省略。故填suggested。
