Bike— Part 1 채점 보고서

제안: Give a direct, grammatically correct response in past tense, add one brief reason or detail, and keep it within 1–3 sentences. Use linking words if adding details (e.g., "because", "so").

예시: No, I didn't have a bike when I was a child because my family lived in a busy city and we usually walked or took public transport. As a result, I didn't learn to ride until I was a teenager.

제안: Start with a clear topic sentence, use correct grammar and a more precise reason, and add one specific example or comparison. Use a linking word such as "because" or "for example" to connect ideas.

예시: Yes, I think bikes are quite popular in my country because many people use them for short commutes in crowded cities. For example, in my city you can see people cycling to work and school, especially during rush hour.

× No, I don't have bike since I was child.

✓ No, I didn't have a bike when I was a child.

Errors: 1) Tense: The student used present simple 'don't have' but the question asks about the past ('when you were a child'), so past simple 'didn't have' is required (Grammar Problem Type ID:5 Past tense issue). 2) Article: 'bike' needs the indefinite article 'a' (Grammar Problem Type ID:22 Article errors). 3) Missing article before 'child' and incorrect form: should be 'a child' and include 'when' to match the time clause. Suggestion: Use past simple for habits or states in the past ('didn't have'), include the correct article ('a bike'), and use the full time phrase 'when I was a child'.

× I think yes, because many people use bike for transportation.

✓ I think so, because many people use bikes for transportation.

Errors: 1) Expression: Use 'I think so' rather than 'I think yes' for natural English (Grammar Problem Type ID:6 Present tense issue — usage of expression in present opinion). 2) Number agreement/article: 'many people' implies plural, so 'bike' should be plural 'bikes' (Grammar Problem Type ID:1 Singular and plural issue). 3) Optionally, 'for transportation' is acceptable; no article needed. Suggestion: Say 'I think so' to express agreement and make the noun agree in number with 'many people' by using 'bikes'.
