Suppose we built a robot to explore the planet Mars. We provide the robot with seeing detectors to keep it away from danger. It is powered entirely by the sun. Should we program the robot to be 1 active at all times? No. The robot would be using up energy at a time when it was not receiving any. So we would probably program it to 2 its activity at night and to wake up at dawn the next morning.
According to the evolutionary (进行的) theory of sleep, evolution equipped us with a 3 pattern of sleeping and waking for the same reason. The theory does not deny that sleep provides some important 4 functions. It merely says that evolution has programmed us to perform those functions at a time when activity would be 5 and possibly dangerous. Howev

解析：M [解析] 空格前为系动词be，空格后为形容词，因此空格处应当填入一个副词。根据本句及下句句意，“我们是否应该为机器人编程，使他们从始至终保持 ---|||________|||---活动状态吗?当然不行。这样的话机器人如果不能补充能量，就会一次耗尽能量”，备选词汇中，可以和active搭配的词汇且符合句意的只有equally“相等地，平等地”，表示“机器人从始至终保持同等的活动状态”，故选择M。
解析：F [解析] 空格前为to，空格后为名词短语，因此判断空格处应当填入一个动词原形。备选词汇中，cease“停止，终止”，cancel“取消，撤销”符合，结合句意，“所以我们应该通过编程设置机器人在晚上 ---|||________|||---活动，第二天黎明再醒过来”，cease符合句意，表示“停止活动”，符合句意，故选F。

和extensive“广泛的，大量的”意思不符合可以排除，regular“定期的，有规律的”和restorative“滋补的，有助于复原的，恢复健康的”中，根据常识，睡眠和起床是个长期且相对固定的有规律的模式，故选择regular。

解析：C [解析] 空格前为系动词，空格后为名词，因此可以判定此处应当填入形容词。本句句意，“(进化)理论仅仅是说当我们行动 ---|||________|||---或是可能产生危险时，进化使我们能够行使那些(恢复)功能”，备选词汇只剩下inefficient“低效的”和extensive“广泛的，大量的”，结合句意，inefficient最符合，故选C。炒蚕蛹
魔方世界纪录解析：J[解析] 空格前为不及物动词，空格后为时间状语从句，因此判断空格处应当填入一个副词。本句意思为“所以当我们处在一个熟悉且安全的环境里时，我们睡眠酣畅；而当我们害怕熊会闯进帐篷里时，我们就睡得 ---|||________|||---”，备选词汇中，lightly“轻轻地，轻松地”最符合句意，表示“睡觉轻，无法安然入睡”，故选J。
解析：A [解析] 经过分析，本句缺少谓语动词，由于主语为theory，因此空格处应当填入动词的第三人称单数形式，且要和for搭配。备选词汇中accounts可以和for搭配，表示“解释”，放入句中，“进化理论很好地解释了不同生物的睡眠差异”，所以选择A。

解析：G [解析] 根据语法这里需要一个副词修饰动词。根据上下文的句义，“时代变了”，“人们已把疼痛和体温、血压、心律以及脉搏看作是身体健康的指标”，可以看出作者在此想表达的意思是在我们这个时代人们太过于关注疼痛了，再结合搭配需要，可知seriously最合适。
解析：N [解析] 根据句法信息可知，此处所需的词汇应与空格前的the fifth一起构成主语pain的同位语，由此可推出，该词可以是一个代词也可以是一个形容词表类属。同时，根据句义作者在此想表达“疼痛被看作是除体温、血压、心律以及脉搏之外的第五项”，根据下文补充成分的关键词important可知，此处是从重要性上对上述五项内容进行对比，所以可知vital最合适。
解析：I [解析] 本句谓语用了一个常见的句型，即sth. be thought/believed/considered adj. (in) doing sth. else，因此此处需要一个动词，同时空格后的名词说明此动词应为及物动词，依据句义只有determine最合适。
解析：D [解析] 根据语法，此处需要填入一个动词做定语从句的谓语，从全句看，此处谓语动词应用现在时，同时先行词problems的形式决定了此动词应为复数形式，空格后的fro
m要求此动词必须能与其构成搭配关系，综合上述考虑，只有range最合适。
解析：O[解析] 与第5小题相同的是，此处也需要填入一个动词做定语从句的谓语。从全句看，此处谓语动词应用现在时，同时先行词physicians的形式决定了此动词应为复数形式，空格后的in要求此动词必须能与其构成搭配关系，根据句义，作者在此指的是“专攻止痛药方向的内科医生”，综上考虑，只有specialize最合适。
解析：F [解析] 根据句法信息，此处需要一个名词与空格前的定语成分一起做介词for的宾语，并与空格后的成分构成限定关系。同时，此成分与本句中提到的depression属对等关系，根据句义可知，作者在这里是指与抑郁症一样的其它心理和社会问题。综上所述，issues最合适。
解析：B [解析] 根据句法信息，此处需要一个谓语动词，且该动词应该是及物动词，其语法形式必须与主语保持一致为单数第三人称。同时，依据句义，作者想表明的意思是这种综合疗法需要很多人的参与，综上所述，只有involves最合适。
解析：J [解析] 根据句法信息，此处需要一个形容词与词组a number of一起构成drugs的限
定成分。同时，根据句义，作者在此分析以前的止痛药在数量等方面存在的缺陷，所以可以看出limited最合适。
解析：C [解析] 根据句法，这里需要一个名词与空格前的限定成分构成句子的宾语，从句义角度
I"m usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago.
