Did you have a bike when you were a child?
점수: 25.0제안: The answer is unclear and does not directly address the question. Give a clear topic sentence that directly answers (yes/no) and then add 1–2 supporting details (who you rode with, where, or what you remember). Use correct vocabulary (e.g., “I had a bicycle” not “I ditched”) and keep it concise (max 3–4 sentences).
예시: Yes, I had a bicycle when I was a child. I used to ride it every day around my neighborhood with my friends, especially in the park near my house. I remember learning to balance on it when I was seven, which was both scary and exciting.
Do you think bikes are popular in your country?
점수: 20.0제안: The response is unintelligible and does not answer the question. Directly state your opinion (yes/no/partly) and give specific reasons or examples (e.g., cycling for commuting, sport, or leisure; bike lanes; weather). Use linking words (because, however, for example) to make the answer coherent and keep it within 3–4 sentences.
예시: Yes, I think bicycles are quite popular in my country because many people use them to commute short distances and save money. For example, in cities there are dedicated bike lanes and shared-bike schemes, which encourage cycling. However, in rural areas cars are still more common due to longer distances.
× Yes, I ditched when I was sick.
✓ Yes, I rode a bike when I was a child, but I stopped when I was sick.
The student's reply 'I ditched when I was sick' is incorrect and unclear. 'Ditch' is not the correct verb for using or riding a bike; it means to abandon or leave something and is informal. Also the original answer doesn't fit the examiner's past-tense question about having a bike as a child. The corrected sentence uses 'rode a bike' to show the action of using a bike in the past and 'stopped' to indicate ceasing due to sickness. Suggestion: use accurate verbs for activities (ride/owned/used) and ensure tense matches the time reference (past simple for completed past actions). This error maps to Sentence structure errors (ID 26) and Incorrect verb usage which affects clarity.
× I don't know how I understand.
✓ I'm not sure how to answer that.
The student's sentence 'I don't know how I understand' is grammatically incorrect and semantically confusing. The phrase 'how I understand' doesn't match the intended meaning of being unsure about an opinion. The examiner asked whether bikes are popular; an appropriate response expressing uncertainty is 'I'm not sure' or 'I don't know.' The corrected sentence 'I'm not sure how to answer that' or simply 'I'm not sure' fits the context and uses correct present simple and infinitive structure. Suggestion: use fixed expressions for uncertainty (I'm not sure; I don't know) and keep the verb forms appropriate (infinitive 'to answer' after 'how' here). This maps to Sentence structure errors (ID 26).
