自行车— Part 1 评分报告

建议: Improve grammar, clarity and add a brief supporting detail. Start with a clear past-tense topic sentence, then give one short reason or example. Keep it natural and within 1–2 sentences.

示例: No, I didn't have a bike when I was a child. My family lived in the city and we relied on public transport, so my parents didn't buy one for me.

建议: Fix article and plural forms, add a linking word and a specific example or reason. Begin with a clear opinion, then use one linking phrase to introduce a specific reason or example. Keep to 2–3 concise sentences.

示例: Yes, I think bikes are very popular in my country. For example, many students ride to school because bikes are cheap and convenient, and city bike lanes make cycling safer.

× No, I don't have.

✓ No, I didn't.

The question 'Did you have a bike when you were a child?' is in the past tense, so the response must use past tense too. 'I don't have' is present tense and mismatched. Use 'I didn't' or 'No, I didn't have one.' to match the past tense and include the object if desired (e.g. 'No, I didn't have a bike'). Note: This fits Grammar Problem Type ID 6 (Present tense issue) because a present-tense form was incorrectly used instead of past tense.

× Yes, I think bike is popular in our country because it's useful for students and everyone.

✓ Yes, I think bikes are popular in our country because they're useful for students and everyone.

The noun 'bike' should be plural ('bikes') when referring to bikes in general. Also the verb must agree with the plural subject: 'are' instead of 'is'. Using 'it's' (it is) refers to a singular item; change to 'they're' (they are) to match 'bikes'. This is a singular/plural error, corresponding to Grammar Problem Type ID 1.
