conditions”在定语从句“sleep takes place”中作地点状语，因此可用in which，它相当于where。 故填which。3.the“theadj.”表示一类人，此处指老年人，与上文中的“the young”相照应。故填the。4.less由语境可知，通常对于成年人的健康而言，八小时的睡眠就足够了，联系下文“may need more”可知，此处指的是另一方面，即有些人的睡眠时间少于八小时也行。less than意为“少于，不到”，符合语境。故填less。5.but根据语境可知，有些人需要的睡眠时间不足八小时，下面指出与此相对的情况，意为：但有的人的睡眠时间却多于八小时，前后句构成转折关系。故填but。6.it根据语境可知，所需睡眠时间的长短往往是对多长时间能满足自己的睡眠需要的正确判断。it is a matter of.为固定句型，意为“这是一个的问题”。故填it。注意首字母大写。7.strength根据空格前的形容词性物主代词“his”可知，此处应用strong的名词形式。故填strength。8.without上文提到，新鲜的空气对酣睡来说是必要的；由此可推知，下文讲的是一些人认为可以露天睡觉并不是没有理由的。此处应填without，和not构成了一个双重否定，表达肯定的含义。故填without。9.neitherneither.nor.意为“既不也不”。此处指临睡前洗浴时，不热也不凉的水温有助于睡眠。故填neither。10.suggested根据语境可知，只有在医生的建议下才能服用安眠药，否则千万不要服用。根据“by a doctor”可知，suggest与其逻辑主语“sleepproducing drug”之间构成被动关系，故此处应用被动语态。该从句的完整形式应为“when it (sleepproducing drug) is suggested.”但在状语从句中，如果从句的主语与主句主语一致，且从句的谓语动词含有be动词时，从句的主语和be动词可以省略。故填suggested。.短文改错(2018石家庄市高三教学质量检测)dear jacob，how are you doing？im writing to invite you to climb mount qianshan.you had already been
