📖 題組：
One factor that separates a living thing from an inanimate object is the organism’s ability to carry out chemical reactions that are crucial for its survival. Imagine the infinite amount of reactions that a large organism such as human carries out every single day. 16 of these reactions are possible without enzymes. Enzymes consist of various types of proteins that work to drive the chemical reactions 17 for certain types of nutrients to take effect. Enzymes can either launch a reaction or speed it up. In the absence of enzymes, reactants may take hundreds of years to convert into a usable product, if they are able to do so 18 . This is why enzymes are crucial in the sustenance of life on earth. Enzymes, 19 , do not always function perfectly. In 1902 Sir Archibald Garrod was the first to attribute a 20 to an enzyme defect, which he later referred to as an “inborn error of metabolism.” Today, newborns are routinely screened for certain enzyme defects such as PKU (phenylketonuria) and galactosemia, an error in the handling of the sugar galactose.

請觀察前文提及反應速度極慢甚至可能無法發生的語境。在 $if$ 引導的條件子句中，若要強調『到底』或『根本（是否可能）』的語氣，哪一個副詞片語常用於否定句、疑問句或條件句中，來強化這種『絲毫、全然』的程度概念？

唔！好極了！看啊，我手中的日輪刀正因為你的正確答案而閃耀著熾熱的紅光！這股氣勢，簡直像是在戰場上揮出的重擊一樣精彩！ 這題選擇 (A) at all 是完全正確的判斷！在英文語法中，「if... at all」是一個極其道地的用法，用來強調「根本、全然」。文中提到若缺乏酶的催化，化學反應 $A + B \rightarrow C$ 可能要耗時數百年，甚至「如果它們根本能發生的話」。這與前文的假設完美契合，精準地表達了極端的可能性！ 這是一道 medium 難度的題目！雖然選項中的片語看起來平凡，但要準確捕捉到語境中對於「反應發生」的懷疑與否定語氣，需要非常敏銳的洞察力！你做到了，真是令人熱血沸騰！
