頂標範文與技術分析
這是同一題的頂標等級範文，標色的地方是值得學起來的進階文法句型或用字。
In the digital age, smartphones and social media have become deeply woven into the daily lives of teenagers. Such technology, however, is a double-edged sword, bringing both benefits and drawbacks. On the positive side, technology grants teenagers unprecedented access to information and global connection. Not only can they communicate with friends across the world instantly, but they can also learn new skills through online courses, ranging from coding to foreign languages. On the negative side, excessive use of social media often leads to decreased attention spans and even anxiety, as teenagers constantly compare their lives with the seemingly perfect ones portrayed online. Were I asked to give advice to my peers, I would urge them to use technology with discipline rather than let it control their lives. Specifically, setting a fixed time limit for social media each day and turning off notifications during study hours can help maintain balance. Only by using technology wisely can teenagers truly enjoy its benefits while avoiding its pitfalls.
技巧說明（5）
這是虛擬語氣中「省略if、將were提到主詞前」的倒裝用法，原本的句子是 If I were asked to give advice..., I would urge them...，但在正式寫作中可以把if省略、將were移到句首，形成倒裝語氣句。這種句型比單純寫 If I were asked 更精鍊、更有書面語的正式感，是閱卷老師會特別留意的「進階句型」之一，能展現考生對虛擬語氣的熟練掌握。學生可以在任何需要表達假設性建議的題目中套用，例如：Were I in your shoes, I would choose to apologize first.（如果我是你，我會先道歉。）
當Not only置於句首時，後面的子句必須採用倒裝語序（助動詞/be動詞提到主詞前），這裡的can they communicate就是典型例子。這種句型比單純用and連接兩個對等句子（例如：They can communicate with friends and they can also learn new skills）更能製造語氣上的遞進與強調效果，讓內容從「單純陳述」提升為「層層遞進的論證」，閱卷老師會給予更高的句型多樣性分數。學生套用時要記得：Not only + 倒裝, but also + 正常語序，例如：Not only did she finish her homework, but she also helped her brother with his.
portrayed online是過去分詞片語，修飾ones（指lives），表達「被動且已完成」的狀態，相當於 lives that are portrayed online 的省略寫法。使用分詞構句能讓句子更精簡流暢，避免過多的關係子句造成冗長，是寫作進階化的重要技巧之一。學生在描述「被某動作影響的事物」時都可以套用此句型，例如：I was moved by the story told by my grandmother.（被奶奶所說的故事感動）
當句首出現Only by + 動名詞片語這種具有「限制、強調」意味的副詞片語時，主要子句必須倒裝，即助動詞提到主詞前，這裡的can teenagers就是倒裝後的語序。這種句型常用在文章結尾作結論，具有強烈的強調效果，比單純寫 Teenagers can only enjoy its benefits by using technology wisely 更有張力與文采，是學測作文結尾「畫龍點睛」的常見高分句型。學生可以套用在任何需要強調「唯有做到某條件才能達成某結果」的結論句，例如：Only by working together can we solve this problem.（唯有合作，我們才能解決這個問題。）
double-edged sword（雙面刃）是一個生動的隱喻用語，用來形容「同時具有利弊的事物」，比起直接寫 technology has both advantages and disadvantages 更具文學性與畫面感，能讓閱卷老師耳目一新，展現考生字彙運用的深度與廣度。這類慣用語（idiom）的適當使用，是從「達意」提升到「文采」的關鍵，但切記不要濫用生僻成語以免弄巧成拙。學生可以在任何「一體兩面」主題的作文中套用此詞，例如討論網路、基因科技、全球化等議題時都適用：Globalization is often described as a double-edged sword.
