问题    Using a computer or smartphone at night can cause us to【C1】______on the pounds, new research has revealed.
   The study found a link between blue light【C2】______—blue light is【C3】______by smartphones and tablets—and increased hunger. It found that exposure【C4】______the light increases hunger levels for several hours and even increases hunger levels【C5】______eating a meal.
   Results of the US study show that blue-enriched light exposure, compared with【C6】______light exposure, was【C7】______with an increase in hunger that began 15 minutes after light onset and was still【C8】______almost two hours after the meal. Blue light exposure has also already been shown to decreased【C9】______in the evening increasing the risk of insomnia.
   Study co-author Ivy Cheung, of Northwestern University, in Chicago, said: "A single three-hour expo sure to blue-enriched light in the evening【C10】______impacted hunger and glucose metabolism. " "These results are important because they suggest that【C11】______environmental light exposure for humans may represent a novel【C12】______of influencing food【C13】______patterns and metabolism."
   The study group【C14】______10 healthy adults with regular sleep and eating schedules who received【C15】______carbohydrate-rich meals. They completed a four-day trial【C16】______dim light conditions, 【C17】______involved exposure to less than 20 lux during 16 hours【C18】______and less than three lux during eight hours of sleep. On day three they were exposed to three hours of 260 lux, blue-enriched light starting 10.5 hours after waking up, and the effects were compared with dim light exposure on day two.
   Ms Cheung said more research is needed to determine the【C19】______of action【C20】______in the relationship between light exposure, hunger and metabolism.
【C13】
选项 A、income
B、input
C、intake
D、insorption
答案C
解析 本题考查名词辨析。结合文意推断，既然接触蓝光照射可以增加饥饿感，那么控制光线照射就可以左右饮食摄入方式了，因此C．intake“(食物、饮料、空气等的)摄取量，吸入量”为正确答案。income“收入”，input“(指信息、资源等的)输入，投入”，in sorption“[医]吸入”，均与文意不符。
