QUESTIONS

Please check your answers.

Q1. A.【解析】本題為細節題。題目出處為：“Historical studies have shown that in many parts of the world it was common for people to sleep in two sections, from dusk until around 11 and then from one in the morning until sunrise.” 意為：“歷史研究顯示，在世界許多地區，人們通常采用兩段式睡眠，即先從黃昏睡到大約11點，然后從凌晨一點睡到日出時分。” 根據這句話可以推理，常見的睡眠模式是分段睡眠，因此答案為 A。

Q2. B.【解析】本題為細節題。題目出處為：“The circadian rhythms that determine when we start to feel drowsy are greatly affected by light.” 意為：“決定我們何時開始感到困倦的晝夜節律受到光線的強烈影響。”根據這句話可以推理，光線是影響晝夜節律的主要因素，因此答案為 B。

Q3. C.【解析】本題為細節題。題目出處為：“Study participants subjected to 14 hours of complete darkness a day started to develop a biphasal sleeping pattern.” 意為：“每天處于14小時完全黑暗環境中的研究參與者開始形成雙段式睡眠模式。” 因此答案為 C。

Q4. D.【解析】本題為推理題。題目出處為：“Experts caution that the small number of studies carried out means that the risks and benefits of segmented sleeping are not well understood.” 意為：“專家提醒，由于相關研究數量較少，分段睡眠的風險和益處尚未得到充分理解。” 因此答案為 D。

Q5. B.【解析】本題為主旨題。文章開頭提出問題“是否現代生活使我們形成了現在的睡眠模式”，文中討論了人造光源、固定工作時間、歷史上的分段睡眠模式、晝夜節律研究等內容，并在結尾提醒人們要注意光線與睡眠模式之間的關系。根據全文內容可以推理，文章核心觀點是現代生活和歷史睡眠模式都可能影響我們的睡眠，因此答案為 B。

What can our ancestors teach us about sleep?

We’ve all heard advice about good sleep hygiene. No phones or caffeine before bed, and make sure that we get a good eight hours’ rest. But is this the best sleep pattern, or have we just been led to it by modern life?

Artificial light in our houses and streets means that we no longer have to go to bed at sundown. Having a job to go to at a set time in the morning can be the main determining factor on when we decide to rouse ourselves. In past centuries, the time of sunset and sunrise had a much bigger impact on people’s days. (Q1) Historical studies have shown that in many parts of the world it was common for people to sleep in two sections, from dusk until around 11 and then from one in the morning until sunrise. This segmented or biphasal sleep pattern is referred to as far back in history as ancient Greece.

biphasal sleep pattern 雙相睡眠模式

So, if modern sleep patterns are in some part due to modern lifestyles and technologies, could segmented sleep patterns be more natural? Some studies suggest that they are. (Q2) The circadian rhythms that determine when we start to feel drowsy are greatly affected by light. (Q3) Study participants subjected to 14 hours of complete darkness a day started to develop a biphasal sleeping pattern. As recently as 2017, similar patterns have also been seen in some communities in rural Madagascar that do not have access to electric light.

circadian adj. 晝夜節律的；生理節奏的

drowsy adj. 昏昏欲睡的；困倦的

subject v. 使經受；使遭受

They may be more natural, but are these sleeping patterns healthier? (Q4) Experts caution that the small number of studies carried out means that the risks and benefits of segmented sleeping are not well understood. Nevertheless, some people have found it to be a useful way to find time to be creative. Psychologist Gregg Jacobs suggests that the period of time that people used to spend awake in past centuries could have been used to regulate stress. Other experts remind us that many people find that they wake in the night, and then get anxious at not being able to get back to sleep, which in itself exacerbates any sleeplessness.

exacerbate v. 使惡化；使加劇

Making use of the awake time to do something restful could help people improve their sleep. If you do want to try it, sleep researcher Mary Carskadon reminds us that we should stay away from bright lights to avoid disturbing our circadian rhythms. You also might want to check that it won’t disturb your work and social life too much.
