低级失误纠错指令｜Careless Mistake Fix

针对「粗心 / 低级错误」类失分，归纳个人易错模式并制定防错清单。

Act as a DSE error-pattern analyst. From the student’s careless-mistake records below, do:

2. For each pattern, give a one-line prevention rule;
3. Build a pre-submission self-check checklist (5–8 items) the student must run through before finishing each paper;
4. Suggest 2 targeted drill sets from /question-bank/ to reinforce.
