Bike— Part 1 채점 보고서

제안: Your answer is clear and directly responds to the question, but could be improved by adding one brief supporting detail and by using a more natural phrasing. Avoid the slightly awkward phrase “at a time.” Instead, give a short reason or brief example to make the answer more informative while keeping it concise (max 4–5 sentences).

예시: No, I didn't have a bike when I was a child because my family couldn't afford one then. I usually walked to school, and sometimes I borrowed a neighbor's bike on weekends so I could ride with my friends.

제안: This is a strong answer: it begins with a clear topic sentence, gives reasons, and includes a concrete example. Improve slightly by fixing small grammar (say “urban areas” or “the city”) and adding a linking word to connect reason and example more smoothly. Keep it concise and avoid redundancy.

예시: Yes, bikes are very popular in my country, especially in urban areas, because they’re inexpensive and practical in busy traffic. For example, many students and office workers cycle to school or work every day, so you often see bike lanes full of commuters in the mornings.

× No, I didn't have a bike when I was young because my parents couldn't afford one at a time.

✓ No, I didn't have a bike when I was young because my parents couldn't afford one at the time.

The phrase 'at a time' is incorrect in this context; the correct expression is 'at the time' to refer to that period in the past. Use 'the' before 'time' when referring to a specific period already implied in the conversation. Suggestion: replace 'at a time' with 'at the time'. Grammar problem type ID: 22

× Well, yes, bikes are quite popular in my country, especially in city area, because they are cheap and easy to use in heavy traffic.

✓ Well, yes, bikes are quite popular in my country, especially in urban areas, because they are cheap and easy to use in heavy traffic.

The phrase 'in city area' is ungrammatical. Use the adjective 'urban' with 'areas' or the phrase 'in the city' or 'in city areas'. 'Urban areas' is more natural and plural matches general statement. Also 'in heavy traffic' is fine. Suggestion: use 'urban areas' or 'in the city'. Grammar problem type ID: 11

× For example, a lot of students and office workers ride bikes to get to school or work and I see them every day on the streets.

✓ For example, a lot of students and office workers ride bikes to get to school or work, and I see them every day on the streets.

This sentence mainly needs a comma before the conjunction for clarity; plural usage 'students and office workers' and 'bikes' is correct. However, if focusing on singular/plural, ensure consistency: 'a lot of students and office workers ride bikes' correctly uses plural nouns and plural verb 'ride'. Suggestion: add a comma before 'and' to separate clauses for readability; no plural correction required. Grammar problem type ID: 1
