【解析】

試題分析：每個人都需要睡眠，充足的睡眠對健康的意義非常重大。為了有一個良好的睡眠，需要考慮諸多因素，如時間，睡覺的場所及睡覺時的溫度等。

【1】needed 考查非謂語動詞。句意：個人所需的睡眠時間取決于他的年齡及睡覺的環(huán)境。分析可知the amount of sleep與need之間為動賓關(guān)系，所以用need的過去分詞形式作定語修飾the amount of sleep，表示“所需的睡眠時間”。故填needed。

【2】which 考查定語從句。句意：個人所需的睡眠時間取決于他的年齡及睡覺的環(huán)境。分析可知介詞+which/whom引導(dǎo)定語從句，the conditions為先行詞，所以選擇which. 定語從句可還原為sleep takes place in the conditions.故填which。

【3】the 考查冠詞。句意：年輕人可能比老年人需要更多的睡眠。分析可知the+adj.表示一類人，如the young年輕人；the poor窮人；the old老年人。故填the。

【4】less 考查代詞。句意：有些人對睡眠的需求量可能比這個量要少，但有些人可能需要更多。根據(jù)后文others may need more可知此處應(yīng)填“有些人需求量少”，故填less。

【5】but 考查連詞。句意：有些人對睡眠的需求量可能比這個量要少，但有些人可能需要更多。根據(jù)less than this amount及后文many need more，可知前后文之間為轉(zhuǎn)折關(guān)系。故填but。

【6】It 考查代詞。句意：滿足個人的需要是一個好的判斷標(biāo)準(zhǔn)。分析可知it作形式主語，to satisfy his need為真正的主語。故填I(lǐng)t。

【7】strength 考查詞性。句意：充足的睡眠能夠讓人恢復(fù)精力并為一天的工作做好準(zhǔn)備。分析可知此處應(yīng)填strong的名詞形式。strength：力量；長處；強(qiáng)項。故填strength。

【8】without 考查介詞。句意：所以有些人認(rèn)為在空氣流通的環(huán)境中睡覺是有實(shí)際意義的，這并不無道理。without reason：不合情理；無緣無故。句中So it is not without reason for some people to think that it is practicable to sleep in the open air為雙重否定表肯定的語氣。故填without。

【9】neither 考查連詞。句意：睡前一個不冷不熱、溫度適宜的沐浴可能會對睡眠有所幫助。分析可知neither hot nor cool but of body temperature表示“既不太冷又不太熱，與體溫適宜的溫度。故填neither。

【10】suggested 考查被動語態(tài)。句意：除非醫(yī)生建議，否則不要吃安眠藥。分析可知句中出現(xiàn)省略，原句Sleep-producing drug should never be taken except when suggested by a doctor可還原為One should never take sleep-producing drug except when he is suggested by a doctor. 時間狀語從句中he和suggest之間為動賓關(guān)系，且時間狀語從句符合省略原則，所以將主語he和be動詞is省略。故填suggested。
