Did you have a bike when you were a child?
分数: 25.0建议: Your response repeated the examiner's question and changed a word, showing misunderstanding and failing to answer. For Part 1 you should answer directly with a short, natural statement (1–3 sentences) and add one supporting detail. Use correct tense (past simple) and avoid repeating the question. Be specific about the bike: whether you had one, when you got it, or how you used it. Example structure: topic sentence + one reason or brief example, using a linking word if needed.
示例: Yes, I had a bike when I was a child. I got it for my eighth birthday and rode it to visit my grandparents every weekend, so it was my main way of getting around.
Do you think bikes are popular in your country?
分数: 30.0建议: You repeated the examiner's question rather than giving an opinion. For this question give a clear opinion in one topic sentence, then add a specific supporting detail or example using a linking word (for example, 'because' or 'for instance'). Keep it concise (no more than 3–4 sentences) and use appropriate vocabulary (popular, common, widespread, commute, leisure).
示例: Yes, bikes are quite popular in my country because many people use them to commute in cities. For instance, in my city there are bike lanes and shared bicycles that many students and workers use every day.

The student used the wrong pronoun/verb form for past reference and also used the wrong noun. 'are' is present tense and doesn't match 'when you were a child' which requires past tense 'were'. This is an incorrect use of pronouns/verb forms referring to time. Change 'are' to 'were' to match past time. Also the noun should match the examiner's question: 'bike' not 'bag'. Suggestion: use 'were' for 'you' in past contexts and check nouns to match the question.

This sentence is already grammatically correct. It uses the present simple tense appropriately to ask about general truth or habitual situation. No change required.
