Grammar accuracy
IELTS Grammatical Range and Accuracy 同时考察句型范围与准确控制，不是复杂句越长越好。结合完整段落检查句子边界、时态、主谓一致、从句和标点，优先找反复出现且影响理解的问题。先把失控长句拆开，再重组成清楚的复合句；比较修改前后是否更准确自然，并把仍会复发的一类错误设为下一篇重写目标。
Grammar accuracy
IELTS Writing 的语法评分看 range 和 accuracy。复杂句如果错误频繁，会比稳定的简单句更影响读者理解。
Band 6 to 7
IELTS Writing 从 Band 6/6.5 到 7，先用一篇真实作文诊断立场、展开、衔接或语法清晰度的主卡分点，再重写一段。
Band range diagnosis
IELTS Writing band score checker 不应只返回看似精确的分数。提交题目和作文后，更值得关注的是保守分数区间、TR/CC/LR/GRA 四项判断、最影响目标分的主卡分点及原文证据。把这些信息转成下一版重写步骤，用修改前后变化判断反馈是否有效；结果不替代官方 IELTS 评分。
Grammar errors at Band 6
雅思写作卡在 6 分的语法问题通常不是难句型太少，而是同一类错误反复出现。先按证据找重复出现的控制问题，再修一个目标句组，而不是一次背完所有语法点。
