让你的每一句论证都有事实依据
📊 一、示范段落
“Regular exercise can greatly improve students’ learning performance. A report from Harvard University shows that students who exercise at least three times a week have 15% better memory retention than those who do not. Furthermore, exercise increases blood flow to the brain, which helps improve concentration. These findings prove that physical activity is an effective way to enhance academic success.”
👉 段落结构：观点 → 数据/研究 → 原因分析 → 总结结论。
🧭 二、常用过渡词
- 引用证据：research has found that, a study conducted by…, experts suggest that
- 分析结果：this demonstrates that, one explanation is that, it can be seen that
- 得出结论：hence, overall, in conclusion
💡 三、写作技巧
- 证据要匹配论点：不要引用无关数据。
- 避免单调引用：可以结合“研究+现象+结论”三步结构。
- 解释是关键：每个数据都应带上意义解读。
- 保持正式语气：避免“I think”“maybe”等口语表达。
⚠️ 四、常见错误提醒
- ⚡️ 只堆数据，缺乏逻辑解释。
- ⚡️ 引用来源模糊，例如 “some people say”。
- ⚡️ 总结句缺失，让段落显得“悬空”。
✍️ 五、练习任务
