Part II. TRANSCRIPT
Naps might not be as good for you as you think
Surely, they're called power naps for a reason? Aren't naps the key to feeling alert, improving your memory and just generally having a great life? Well, they can be, but things aren't quite that simple.
(Q1) It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. Our circadian rhythms are responsible for the notorious lull that many of us feel in the early afternoon. This is the best time for a nap. Some companies have installed sleep pods for their employees, hoping to benefit from increased productivity and cognitive performance. But it is also true that naps can cause problems.
circadian adj. 生理节奏的，昼夜节律的
notorious adj. 声名狼藉的，众所周知的（常指不好的事情）
lull n. 间歇，平静期
pod n. 小舱，隔间
cognitive adj. 认知的
Let's start by thinking about the length. (Q2) A true power nap should be less than half an hour. Any longer, and it becomes hard to rouse yourself from. Any benefits in terms of alertness are likely to disappear with the grogginess that results from a longer period of slumber.
grogginess n. 昏昏沉沉，虚弱无力
slumber n. 睡眠，微睡
This isn't the only issue. Naps have been linked to conditions such as diabetes, high blood pressure and cardiac problems. However, it's not clear whether these are direct results, or stem from the impact of napping on our sleep habits. (Q3) If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained.
cardiac adj. 心脏的
ingrain v. 使根深蒂固
Of course, in the same way that naps can lead to bad sleep, it's also true that bad sleep can lead to wanting to take more naps. (Q4) So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case. Are there any potential health issues that could be causing insomnia? Or are work pressure stopping you from getting enough sleep?
insomnia n. 失眠

Q2.【答案】A
【解析】细节题。题目出处：A true power nap should be less than half an hour. 意为：“真正的有效小憩时间应控制在半小时以内。。” 文章明确指出，有效小睡的时间应该少于半小时，超过这个时间可能会导致昏昏沉沉，并抵消小睡的益处，因此正确答案为A。
