Which of the following statements does the speaker support? [br]
A large study in JAMA Pediatrics reported an 87% increased risk of autism among children born to women taking antidepressants. But 87% higher than what? About 1% of babies worldwide are born with autism. And while an 87% increase in relative risk sounds like a lot, it represents a tiny absolute increase in risk. The study also couldn’t establish for sure whether the drugs were responsible for the autism link.
Modern technology seems particularly adept at messing with our sleep schedules. Smartphones, tablets and computer screens all emit a bluish light; great for saving power, but also just right for disrupting our body clocks. The lights on these electronic devices are colored like enriched moonlight. These blue lights drastically suppress the production of melatonin, the hormone that controls the body’s day-night cycle.
选项
A、Our body clocks.
B、The production of melatonin.
C、Backlit devices.
D、Electronic lights.
答案
C
解析
讲话者认为智能手机、平板电脑等现代科技产品发出的蓝光影响睡眠。这些产品可以用“backlit devices”来概括。melatonin意为“褪黑色素”。
