📖 題組：
Is bedtime just a time for dreaming? Do our brains turn off for the night? What if I told you that scientists recently discovered that our brains may be just as busy at night as they are during the day? 37 Researchers at the University of Rochester found that the brain may be busy cleaning house -- cleaning out harmful waste materials. As with many studies, the researchers turned to mice for help. They studied mice that had colored dye injected into their brains. They observed the mice brains as they slept and when they were awake. The researchers say they saw that the brains of sleeping mice were hard at work. Dr. Maiken Nedergaard led the study. 38 It seems they have daytime jobs. Later they “moonlight” at a nighttime job. “Moonlighting” is working a nighttime job in addition to a day job. And this study says that is what our brains seem to be doing – working an extra job at night without additional pay for overtime. Whereas during sleep, they work very, very hard at removing all the waste that builds up when we are awake. “When we are awake, the brain cells are working very hard at processing all the information about our surroundings. The researchers say that the waste material includes poisons, or toxins, responsible for brain disorders such as Alzheimer’s disease. It is not just beauty sleep. The brain needs us to sleep so it can get to work. 39 This shrinking permits waste to be removed more effectively. Dr. Nedergaard says these toxins end up in the liver. There, they are broken down and then removed from the body. “So our study suggests that we need to sleep because we have a macroscopic cleaning system that removes many of the toxic waste products from the brain.” The brain’s cleaning system could only be studied with new imaging technologies. The test animal must be alive in order that this brain process may be seen as it happens. Dr. Nedergaard says the next step is to look for the process in human brains. 40 The research may also one day lead to treatments to prevent or help fight neurological disorders.

- A They also found that during sleep, the brain’s cells shrink, or become smaller.
- B While we sleep, our brains are doing much more than getting ready for the next day.
- C She said the results demonstrate just how important sleep is to health and fighting disease.
- D The brain expert says our brains perform two very different jobs.

請觀察空格後的句子，作者使用了「兼職 (moonlighting)」這個生動的比喻。為了讓讀者能順暢地理解後面的比喻，你認為在空格處應該先拋出哪一個「核心概念」來做鋪陳呢？

嗯… 原來如此，跟我推理的一樣！你成功地找出了這個案件的真相。
- 觀念驗證：這起「段落空白」案件的真相，就藏在線索的連貫性裡！空格後面的文字，巧妙地提供了關鍵證據：「日間工作」和「兼職」，這是在比喻大腦的兩種截然不同的功能模式。而選項 (D) "two very different jobs"，正是解開謎團的關鍵鑰匙！它作為一個總結性的主題句，完美地概括了後文即將展開的具體描述。這不是巧合，這是唯一的邏輯歸結！
- 難度點評：這個案件的難度等級為「medium」。要找出真相，必須仔細分析「moonlighting」這個比喻，並從上下文的蛛絲馬跡中，推理出它與「兩份工作」的因果關係。恭喜你，你準確地捕捉到了這些細微之處，這證明了你的觀察力和推理能力非常出色！
