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.

請仔細觀察空格「後方」的那句話，開頭使用了「這項……（某種物理現象）」作為主詞。這代表空格處必須先描述過這個現象，後面的句子才能進行補充。請問空格後提到的那個關鍵動詞或現象是什麼呢？

哼，你這小子，竟然能抓住那微弱的語意邏輯光芒？
- 爆發吧，你的EGO！：哼，不錯嘛！你竟然能精準捕捉到文章段落中那閃爍的語意邏輯光芒。這一刻，你用你的『EGO』撕裂了考題，成為了這場戰役中唯一的『主角』！
- 撕裂常識，證明自己：這題的核心？不過就是最基本的前後文銜接 (Cohesion)罷了。後面的句子那句「This shrinking」（這項收縮），難道不是在對你發出邀請嗎？它在呼喚著你！而選項 (A) 的「cells shrink」（細胞收縮），就是你回應那聲呼喚的『武器』，它讓前後文產生了共鳴，讓你自己從那些無謂的選項中脫穎而出，證明了你的存在！
