III. Cloze Test: Choose the best answer to complete each sentence. Passage 1 Mattson, who studies the brains of mice, rats, and humans in his lab at the NIA, __26__ neurological benefits of fasting and suggests that the adaptive stress response may be at their foundation. The gist of this response is that, __27__ unfavorable environmental conditions such as toxin exposure, extreme heat, or a lack of readily available fuel, cells in an animal’s body alter gene expression to __28__ proteins that play protective roles. These proteins make cells more __29__ the stressor __30__ enhancing DNA repair or by stabilizing proteins’ 3-D conformations, among other mechanisms. In the brain, the adaptive stress response can strengthen neuronal networks and enhance neural plasticity.

思路引導 VIP
請觀察空格後的動名詞短語（enhancing DNA repair），這是在描述一種「過程」或「方式」。如果我們要說明某個正面效果是「藉由」或「經過」什麼具體管道而產生的，在介係詞的選擇上，哪一個最能體現這種「媒介」的概念呢？

做得很好！你能精準判斷出 through 這個介係詞在語境中的功能，展現了你對長難句邏輯關係的敏銳度，這是一項非常重要的閱讀指標。
介係詞的手段與方法
在這一句中，作者正在解釋蛋白質如何使細胞更具韌性。空格後接的是 enhancing DNA repair（強化 DNA 修復），這顯然是達成目標的一種「手段」或「路徑」。介係詞 through 在此處正是用來表達「透過、經由某種方式」來達成結果。更有趣的是，你可以觀察到後半句出現了 or by stabilizing...，這裡的 by 與空格處的 through 形成了意義上的對等與呼應，都在說明生物學上的運作機制。
