Bike— Part 1 채점 보고서

제안: Your answer is direct but too short and lacks detail. Provide a brief topic sentence then add one or two specific supporting details using linking words (e.g., “because”, “so”, “but”) to explain why you didn’t have a bike or what you used instead. Keep it natural and under five sentences.

예시: No, I didn’t have a bike when I was a child because my parents thought it was unsafe for me to ride on busy streets. Instead, I usually walked to school or took the bus, so I didn’t learn to ride until I was a teenager.

제안: Your answer shows the right idea but is disfluent and contains unnecessary phrases (e.g., “I'm sorry”, “Yeah. What's up?”). Start with a clear topic sentence, then add one or two specific supporting details using linking words (e.g., “for example”, “because”, “therefore”). Avoid filler language and be concise (max five sentences).

예시: Yes, bicycles are very popular in my country because they are cheap and convenient for short trips. For example, many children ride to school and adults use bikes for commuting in cities, so cycling is a common sight on most streets.

× Yes, I'm sorry. Yes, it's very popular in our country.

✓ Yes, I'm sorry. Yes, they're very popular in our country.

The student uses 'it's' (it is) to refer to 'bikes' which is plural. This is a third person singular vs plural agreement issue. Replace 'it's' with 'they're' (they are) to match the plural noun 'bikes'. Suggestion: Always identify the noun number (singular/plural) and choose the appropriate verb form: 'it is' for singular, 'they are' for plural.

× I saw a lot of kids ride bicycles.

✓ I saw a lot of kids riding bicycles.

The sentence combines past tense 'saw' with a bare infinitive 'ride', which is unnatural here. The correct structure uses a participle clause 'kids riding' to describe simultaneous action in the past. Use 'kids riding' or 'kids who were riding'. Suggestion: After verbs of perception like 'saw', use either the -ing form for ongoing action ('saw kids riding') or the full infinitive with 'to' for purpose, but not the bare infinitive in this context.
