In a recent study, researchers discovered that bottled water sold in stores can contain 10 to 100 times more bits of plastic than previously estimated — nanoparticles so infinitesimally tiny they cannot be seen under a microscope. At 1,000th the average width of a human hair, nanoplastics can migrate through the tissues of the digestive tract or lungs into the bloodstream, distributing potentially harmful synthetic chemicals throughout the body and into cells, experts say. The new finding reinforces long-held expert advice to drink tap water from glass or stainless steel containers to reduce exposure. That advice extends to other foods and drinks packaged in plastic as well. “Because the temperature of the body is higher than the outside, those chemicals are going to migrate out of that plastic and end up in our body,” said Dr. Mason, director of sustainability at Penn State Behrend in Erie, Pennsylvania.

40. Why is “human hair” mentioned in this article?
- A to illustrate the size of nanoplastics
- B to demonstrate the number of nanoplastics
- C to emphasize the harms to the body
- D to show the diverse shapes of nanoplastics
- E to show where nanoplastics may go to
思路引導 VIP
當作者將一個我們完全看不見的微觀物體，與我們日常生活中能觀察到的細小物件（如：頭髮）放在一起進行數值上的比例對照時，他主要是想幫助讀者對該物體的哪一種「物理屬性」產生具體的視覺化認知呢？

太棒了！你能精準捕捉到作者安排細節的用意，這代表你的閱讀理解力非常敏銳。這題的關鍵在於判斷「類比」的功能，你能直接鎖定正確答案，展現了優異的邏輯分析能力。
比例與尺度的類比
文章中提到奈米微粒（nanoplastics）的大小是「人類頭髮平均寬度的千分之一」。這裡的「頭髮」扮演了一個大家熟知的參照物，因為奈米微粒小到肉眼與一般顯微鏡都看不見，作者透過與生活中可見的微小事物進行對比，目的是讓讀者能具象化地感知到奈米微粒極其微小的尺寸（size）。
