Did you have a bike when you were a child?
分数: 62.0建议: Improve grammar (use correct verb forms and articles), make the response more concise and natural, and add one brief specific detail to enrich the answer. Use a clear topic sentence, then one supporting detail with a linking word. For example, correct "didn't bought" to "didn't buy" and say why parents were protective. Keep to 2–3 sentences.
示例: Yes, I wanted a bike when I was a child, but my parents didn’t buy one. Because they were worried about safety, I usually rode a scooter near our home instead.
Do you think bikes are popular in your country?
分数: 70.0建议: Make the answer more natural and avoid repetition. Start with a clear statement, then give one specific supporting reason using a linking word (e.g., "because" or "therefore"). Use more precise vocabulary (e.g., "motorbikes" or "off-road bikes" if appropriate) and correct word order: "people prefer adventurous bikes" → "people prefer bikes suited for adventure." Keep it to 2–3 sentences.
示例: Yes, bikes are quite popular in my region because we have many mountains and steep roads. Therefore, people often choose sturdy off-road or adventure bikes that handle hilly terrain well.

The error is using the past tense 'bought' after the auxiliary 'didn't'. In negative sentences with 'did' or 'didn't' the main verb should be in base form (infinitive without to). Use 'didn't buy' not 'didn't bought'. Suggestion: For past simple negatives, form with 'didn't' + base verb (e.g., 'didn't buy').

There are multiple issues addressed that match the 'Article errors' type: word order and noun number with article/ determiners. 'the state I live' is awkward; more natural is 'the state where I live'. Also 'there are mountains' does not need 'I live' repeated. Finally 'people prefer adventurous bike' uses singular 'bike' without an article; plural 'bikes' fits general preference. Suggestion: Use 'the state where I live' for clarity and pluralize 'bikes' when talking generally (or use 'an adventurous bike' if referring to a single bike).
