台灣考生衝 Band 7 最大的迷思是「要背很難的字」。事實上——Band 7 的詞彙分數不是看難度，是看精準度。用 10 個精確的 significant, beneficial, substantial 贏過用 5 個生硬的 ubiquitous, quintessential, paradigmatic。
核心原則：精準 > 難度
Cambridge 評分標準 Band 7 原文："uses a sufficient range of vocabulary to allow some flexibility and precision"。關鍵字是 precision（精準），不是 rarity（罕見）。
Band 6 = 模糊的對：It's a big problem. Band 7 = 精準的對：It's a pressing challenge. Band 8 = 過度炫技：It's a paradigmatic quandary. — 如果不自然，反而扣分。

練習：改寫這一段
原文（Band 6 等級）：
Many students today use the internet a lot for their studies. This is good because they can find many things easily, but there are also bad sides. Some students think it is easy to copy information, which is a big problem. Teachers should help students to use it correctly.
你的任務：替換 5 個 Band 6 詞彙為 Band 7 版本，保持意思不變。
參考改寫（Band 7 版）
A considerable number of students today rely heavily on the internet for academic work. While this offers substantial advantages — information can be accessed effortlessly — it also has notable drawbacks. Some learners are tempted to copy material from online sources, which raises a serious issue of academic integrity. Teachers therefore have a crucial role to play in guiding students toward responsible use.
