Did you have a bike when you were a child?
점수: 30.0제안: Your answer is brief and has grammatical errors. For Part 1 you should answer directly, use correct tense, and add one or two supporting details. For example, say whether you ever had one as a child and explain why not or why you still don't have one. Use past tense when talking about childhood and avoid contractions like "don't" with time markers. Keep it natural and no more than 3–4 sentences.
예시: No, I didn't have a bike when I was a child because my family lived in a hilly area and it wasn't practical. Even now I don't own one because I prefer public transport for long commutes.
Do you think bikes are popular in your country?
점수: 55.0제안: Your answer addresses the question but has grammar and vocabulary issues and is repetitive. Improve by using correct singular/plural forms, adding a reason with a linking word, and giving a specific example or comparison. Limit to 3–4 sentences and use linking words like "because", "for example", or "so" for coherence.
예시: Yes, I think bicycles are quite popular in my country because they are an affordable and convenient way to travel short distances. For example, many students and office workers ride bikes to avoid traffic, so you can see bike lanes crowded during rush hour.
× No, I don't have till now.
✓ No, I haven't had one until now.
The student used the simple present negative 'I don't have' with a time expression referring from past to present ('till now'), which requires the present perfect. Use 'haven't had' to indicate possession up to the present. Also include the object 'one' (a bike) for clarity. Suggestion: use present perfect for actions or states continuing to the present (I haven't had a bike until now).
× Yes, I think bike are popular in my country because many people use bike.
✓ Yes, I think bikes are popular in my country because many people use bikes.
The noun 'bike' is countable and refers to bikes in general, so it should be plural ('bikes') and must agree with the plural verb 'are'. Also pluralize the second 'bike' ('use bikes') to match general reference. Suggestion: use plural nouns when speaking about things in general (bikes are popular; many people use bikes).
× They go many places with bike.
✓ They go to many places by bike.
The original sentence omits the preposition 'to' after 'go' and uses the wrong preposition 'with' for the means of transport. English commonly uses 'go to [places]' and 'by' for transport ('by bike'). Also 'bike' should be singular when used with 'by' to indicate mode of transport. Suggestion: say 'They go to many places by bike.'
