这次总用了51分钟，这次给了6.5，后面特花了3分钟检查单复数，自己就发现很多错误。 下面是自己的错误笔记总结。还没深入去分析优化过后的文章，明天继续。 1. 不要说 "learning about knowledge" ❌ learning about knowledge ✅ gaining knowledge 📌 规则：不要把 learn / study 和 knowledge 搭配！ 改用 gain、acquire 或 expand one’s knowledge 更学术自然。 💡 好句示例： The course helped me gain valuable knowledge. Students should aim to expand their knowledge of the subject. 2. to 后面要接动词，不是名词 ❌ impossible for students to success ✅ impossible for students to succeed 📌 规则：to 后面接动词原形（infinitive），success 是名词，要改成 succeed。 💡 好句示例： Hard work allows people to succeed. He is likely to succeed in his new role. 4. well-know → well-known ❌ a well-know entrepreneur ✅ a well-known entrepreneur 📌 规则：well- 作前缀时，后面必须跟过去分词形式（-ed / -en 等）。 💡 好句示例： It is a well-known fact. She is a well-respected teacher.
