问题     Forget milky drinks, hot water bottles or curling up with a good book. The real secret to a good night’s sleep may be where you sit at work.

"Office workers with more light exposure at the work place also【C10】________have better sleep quality, more physical activity and a better quality of life." A sunny day is equivalent to about 10,000 lux or higher of light. However indoor office lighting【C11】________provides only about 300 to 500 lux.

【C17】
选项 A、Regular
B、Excessive
C、Massive
D、Adequate
答案D
解析 根据空格后的句意“接触阳光对于控制体内的生物钟起着至关重要的作用”，本文论述的是办公室人员缺乏阳光对睡眠及身体造成的影响，反之，要使睡眠好，就要多接触阳光，故选D项Adequate“充足的”。A项Regular“定时的”。本文并无相关证据证明晒太阳的规律性对生物钟有影响。B项Excessive意为“过多的”，一般具有否定意义。C项Massive意为“大量的”，根据医学常识，大量的晒太阳也对身体有害，故不可选。
