🤔 你滑 IG 時怎麼看貼文？
坦白說：你滑 IG 的時候，一則貼文你看多久？3-5 秒對吧？先看圖，瞄一眼前兩行文字，決定要不要繼續讀。這就是 Skim（略讀）。
然後你在留言區找關鍵資訊——誰標記了誰？哪句好笑？直接掃到關鍵字。這就是 Scan（掃讀）。
學測閱讀一篇 300-400 字，你只有 8 分鐘。逐字讀 = 穩死的。這堂課教你用滑 IG 的方式讀學測文章。
🔑 一句話總結：Skim 抓大意（30秒），Scan 找答案（關鍵詞定位）。兩個加起來 = 8 分鐘一篇。
🔑 Skim vs Scan：別再搞混了
| Skim（略讀） | Scan（掃讀） |
|---|
| 目的 | 抓文章主旨、結構 | 找特定資訊、答案 |
| 怎麼做 | 讀第一段＋最後一段＋每段第一句 | 從題目抓關鍵詞→回文章定位→讀前後兩句 |
| 時間 | 30-45 秒 | 每題 20-30 秒 |
| 像什麼 | 看 IG 貼文預覽決定要不要點 | 在留言區找某個人的回覆 |
| 考試時機 | 拿到文章第一步 | 看完題目後逐題使用 |

下面是一篇短文，給自己 30 秒 Skim，然後回答「主旨是什麼？」（答案點擊揭曉）
🌿 The Rise of Urban Gardening
In recent years, city dwellers around the world have turned balconies, rooftops, and even abandoned lots into thriving gardens. This trend, known as urban gardening, is not just about growing fresh tomatoes or herbs—it represents a deeper shift in how people think about food and community.
Many urban gardeners say they started because they wanted to know where their food came from. After watching documentaries about industrial farming and pesticide use, they decided to take control of their own plates. Others point to the mental health benefits: studies show that gardening reduces stress, improves mood, and provides a sense of accomplishment that is hard to find in a typical office job.
The movement has also brought neighbors together. In cities like Detroit and Berlin, community gardens have transformed vacant lots into vibrant gathering spaces where residents of all ages work side by side. Local governments are taking notice, too. Several cities now offer tax incentives for building green roofs and converting unused spaces into gardens.
Of course, urban gardening has its challenges. Limited space, contaminated soil, and lack of sunlight in dense urban areas can make growing food difficult. But advocates argue that with creative solutions like vertical gardens and hydroponic systems, these obstacles can be overcome. As more people seek sustainable, healthy lifestyles, the urban garden may become as common as the corner coffee shop.
⏱ 30秒過去了！這篇文章主要講什麼？
[ 點我看答案 ]
✅ 主旨：都市園藝（Urban Gardening）的興起——人們為什麼開始在都市種菜（健康/環保/社交）、帶來的社區改變、以及面臨的挑戰。
🔍 Skim 關鍵點：
• 第一段：urban gardening trend（主題）
• 第二段第一句：wanted to know where food came from（原因1）
• 第三段第一句：brought neighbors together（原因2）
• 第四段第一句：urban gardening has its challenges（轉折→挑戰）
你不需要讀每個字！只讀每段第一句 + 最後一段關鍵詞 = 抓到80%主旨。
🎯 Scan 實戰：關鍵詞定位術
現在用同一篇文章，練習 Scan。假設題目問你：
❓ 題目：According to the passage, what is one solution to the challenges of urban gardening?
Step 1：從題目抓關鍵詞 → "
solution"、 "
challenges"、 "
overcome"
Step 2：回想 Skim 時看到的——最後一段有 "challenges" 和 "obstacles can be overcome"
Step 3：定位到最後一段，讀前後兩句
[ 找到答案了嗎？點我看 ]
→ vertical gardens and hydroponic systems（垂直花園和水耕系統）
再練一題
❓ 題目：What mental health benefits of gardening are mentioned?
[ Scan 定位 → 點我看 ]
關鍵詞：mental health benefits → 第二段最後一句
定位句："studies show that gardening reduces stress, improves mood, and provides a sense of accomplishment"
✅ 答案：減少壓力、改善心情、提供成就感。
⚠️ 學測 Skim & Scan 最常見的 3 個陷阱
陷阱 1：把 Skim 當成「跳著讀」
有些人說「好，Skim 就是跳著讀」，結果跳過關鍵轉折詞（However, But, Yet, Although），整篇文章意思看反！
✅ 正確做法：Skim 時特別注意轉折詞。However 後面才是重點，前面只是鋪墊。
陷阱 2：關鍵詞找太長
「我找 "environmental sustainability challenges"」→ 文章根本沒這種詞。關鍵詞要短、核心。
✅ 正確做法：只抓 1-2 個核心字：sustainable、challenge、solution。人名、地名、數字最好找。
陷阱 3：找到關鍵詞就停，不讀前後文
Scan 到關鍵詞 → 只看那一句 → 答案選錯（因為前一句是 "Although..." 整個語境相反）。
✅ 正確做法：找到關鍵詞後，讀前一句＋關鍵句＋後一句。確保語境正確。
