Common mistake
Rare words with unnatural collocation weaken the Lexical Resource signal.
IELTS Writing tool boundary
IELTS vocabulary checking should start with accuracy and collocation.
Turn the tool result into diagnosis, evidence, and the next revision step first. No official score promise and no ghostwritten answer.
Use diagnosis to decide what to revise first.
Diagnostic evidence
If the same broad words repeat, replace the function of the expression instead of mechanically finding synonyms.
What to prepare before submitting
Submit the full paragraph and prompt because vocabulary fit depends on argument context.
What to revise after feedback
Repair one collocation group first, then replace one vague word.
- Whether collocation is natural
- Whether meaning is precise
- Whether repetition weakens expression

Writing checker
使用 IELTS Writing checker 时，分数之外还要看主卡分点。更有用的是找出 Task Response、Coherence、Lexical Resource 或 Grammar 中最影响训练的主卡分点。
Essay feedback
在线 IELTS 作文反馈要比总评和错误清单多走一步。用原文证据定位一个主卡分点，对照评分维度，再完成一次可检查的重写。带着自己的原文逐项检查，再用一次有目标的重写验证判断。
Writing feedback service
IELTS writing feedback service 页面强调证据、主卡分点和重写目标，避免只给笼统建议。准备原题、作文、目标分数和你最想确认的问题。
Lexical Resource
IELTS Lexical Resource 看的是用词准确，难词多少是其次。更重要的是词义准确、搭配自然、话题贴合，同义替换也要守住题目原意。
LR 6 vs 7
IELTS Lexical Resource 从 Band 6 到 7，关键是减少用偏的同义替换、搭配错误和话题偏离，词换得更难是其次。准确性比炫词更先影响理解。
Vocabulary control
IELTS Writing 的 Lexical Resource 看词义、搭配、语域和准确性。高级词数量只是其中一小部分；用错的难词，比简单准确的词更伤分。
AI evaluator
IELTS Writing AI evaluator 的价值在于快速出 band 和列出错误之外，还能把题目和原文映射到 TR/CC/LR/GRA，找出最影响目标分的主卡分点并引用具体证据。好的评估会说明分数的误差范围，把问题收窄成下一版可验证的段落修改步骤，让学习者自己完成重写；结果用于学习参考，官方 IELTS 分数以考试为准。
Band 6.5 plateau
IELTS Writing 卡在 6.0-6.5 时，先找出最拖分的一个问题：理由展开、段落衔接、用词还是语法，下一篇就围着它改。语法、用词、衔接都被点到了，下一篇要先挑一个来改。
