Why complex sentences become messy
When one sentence carries concession, cause, and example at once, the main structure can disappear. Let one sentence complete one relationship first.
Grammar gap
From Grammar 6 to 7, the answer is control; making every sentence complex often backfires.
Around Band 6, an essay may attempt complex sentences, but frequent errors or sentence drift affect meaning. Band 7 needs stable control.
Stabilize first, then increase range.
Band 6 risk
There are attempts at complex structures, but clauses, agreement, or punctuation make the reader pause.
Band 7 signal
Sentence patterns vary while most sentences stay clear and controlled.
What to revise after checking
Choose six sentences that most affect understanding. Rewrite them as accurate short sentences first, then combine into one controlled complex sentence.
- Whether the main clause is complete
- Whether clause relationships are clear
- Whether punctuation helps the reader understand

Grammar accuracy
IELTS Grammatical Range and Accuracy 同时考察句型范围与准确控制，句子写得稳比写得长更重要。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。长句里反复出现主谓、从句或标点问题。
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。带着原文完成检查，再用重写验证是否真的改善。
Band range diagnosis
IELTS Writing band score checker 给出分数之外，还要说明依据。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 修改步骤，用修改前后变化判断反馈是否有效；结果用于学习参考，官方 IELTS 分数以考试为准。
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。
