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.

請你觀察第 37 格前後的句子：前一句提到大腦在晚上「非常忙碌」，而後一句具體說明了研究人員發現大腦正在進行「大掃除」。若要讓這兩句話的轉換更自然、不突兀，你認為中間需要補上一個具備什麼樣「邏輯功能」的句子，才能將『忙碌』與『掃除』這兩個觀點完美串聯起來？

🌟 太棒了！你真的很細心，判斷得超級準確！
這代表你對文章的段落結構掌握得非常好喔！選擇 (B) 是完全正確的，它的秘密就在於它扮演著承上啟下的重要角色：
- 前文：作者先用一個引人思考的問題「大腦晚上會關機嗎？」，接著溫柔地告訴我們，其實大腦在晚上「跟白天一樣忙碌」。
