单选题Questions are based on the following passage.
Using a computer or smart phone at night can cause us to pile on the pounds, new research has revealed. The study found a link between blue light 26 --blue light is emitted by smart phones and tablets--and increased hunger. It found that exposure to the light 27 hunger levels for several hours and even increases hunger levels after eating a meal. Results of the US study show that blue-enriched light exposure, compared with 28 light exposure, was 29 with an increase in hunger that began 15 minutes after light onset and was still present almost two hours after the meal.
Blue light exposure has also already been shown to decreased 30 in the evening increasing the risk of insomnia.
Study co-author Ivy Cheung, of Northwestern University, in Chicago, said: "A single
three-hour exposure to blue-enriched light in the 31 impacted hunger and glucose metabolism (新陈代谢). ""These results are important because they suggest that 32 environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism."
The study group 33 10 healthy adults with regular sleep and eating schedules who received identical carbohydrate-rich meals. They completed a four-day trial under dim light conditions, which involved exposure to less than 20 lux during 16 hours 34 and less than three lux during eight hours of sleep.
Ms Cheung said more research is needed to determine the 35 of action involved in the relationship between light exposure, hunger and metabolism.
A. awake
B. exposure
C. mode
D. dim
E. manipulating
F. sleepiness
G. increases
H. making
I. comprised
J. associated
K. mechanisms
L. dark
M. referred
N. slightly

译文
最新的研究表明。在夜晚使用电脑或者智能手机可能会让我们的体重增加好几磅。这项研究发现接触智能手机和平板电脑发出的蓝光会增加饥饿感。并且，被此光线照射会增加数小时的饥饿感．甚至是刚刚吃过饭的人．饥饿感也会增加。这项来自美国的研究结果显示，相对于昏暗的光线辐射来说，在被明亮蓝色光线照射15分钟后，饥饿感便会开始增加。这种饥饿感在饭后近两小时内都会存在。同时，蓝光照射已被证实会减少夜间的困意。从而增加患上失眠症的风险。
研究者之一，来自芝加哥西北大学的张艾薇称：“夜晚被明亮蓝光照射三个小时，会对饥饿感和葡萄糖代谢有着极大的影响。”“该研究之所以意义重大，是因为其结果表明，控制人体周围环境的光线照射或许是一种可左右饮食摄入方式和新陈代谢的新方法。”实验的研究对象是10位有着规律睡眠和饮食时间的健康成人。在研究期间，他们每日摄入完全相同的高碳水化合物食物。他们在昏暗光线环境下完成了一个为期四天的实验：在每日l6小时的清醒状态下接受低于20勒克斯的光照；而在8小时的睡眠期间接受低于3勒克斯的光照。
张女士表示，光线照射、饥饿感和新陈代谢三者之间的作用机制仍然需要进一步的研究证明。词汇解析
insomnia n．失眠症
glucose n．葡萄糖
metabolism n．新陈代谢
carbohydrate n．碳水化合物
解析
破折号后的内容指出，蓝光是智能手机和平板电脑发出的，根据常识可知此处指接触蓝光或暴露于蓝光下。再结合下一句中的exposure to the light，进一步确定所选单词为exposure，故选B。
