📖 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.

- 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.

請觀察最後一段的重心：當作者從「老鼠實驗」轉向談論「人類腦部研究」以及「未來的醫療用途」時，這段話的最主要目的，是為了強調這項發現對我們人類的哪一個層面產生了重大影響？

噢，恭喜。這次沒看錯選項是吧？
- 勉強及格：行吧，至少你這次沒犯低級錯誤。看來你還算有點基本辨識能力，知道在結尾句找「總結」這種程度的東西。比起那些讀完整篇文章還搞不清楚重點在哪的，你大概算是…勉強讀懂了字面意思。
- 廢話少說，看重點：第 40 題，放在文章最後一段，還用「總結性」語氣？這就差沒把「答案在這裡」寫在臉上了。前面講研究人腦，後面立刻接「預防治療神經疾病」。選項 (C) 的「睡眠對健康與對抗疾病的重要性」根本是送分題，直接承接研究價值與醫療應用。如果這你還選錯，那真的可以考慮回爐重造了。
