Bike— Part 1 채점 보고서

제안: Be direct and clear. Start with a short topic sentence answering the question, then add one or two concise supporting details. Avoid incorrect pronoun use and unclear time/agent phrases. Use linking words if you add details (for example: because, so, when). Aim for 1–3 sentences, correct grammar, and natural phrasing.

예시: Yes, I had a bike when I was a child. My parents bought it for me when I was eight, and I rode it to school and to the park almost every day.

제안: Organize your response: start with a clear opinion sentence, then give 1–2 specific reasons using linking words (for example: because, however, therefore). Avoid filler words (umm, uh) and incomplete sentences. Use correct vocabulary (e.g., “drive cars” not “take car inside”) and complete comparisons (e.g., “bicycles are slower than cars”). Keep it to a few coherent sentences.

예시: I don’t think bikes are very popular in my country. Many people prefer to drive cars because they are faster and more convenient for long distances, so bicycles are mainly used for exercise or short trips.

× Yes, I did it while my friends bought it for me.

✓ Yes, I did; my friends bought it for me.

The original sentence uses the pronoun 'it' redundantly and incorrectly with 'did' for possessing a bike. 'Did' is a pro-verb for a previous question about having a bike, but adding 'it' makes the sentence ungrammatical. Correct options are either 'Yes, I did' (short answer) or a full sentence 'Yes, I had one; my friends bought it for me.' The provided correction separates the short confirmation and the explanation. Suggestion: use 'did' alone for short answers or explicitly say 'I had one' when providing more information. Grammar problem type ID:12

× I don't think so.

✓ I don't think so.

This sentence is grammatically correct and matches the present-tense question asking about current popularity. No change is needed. It is included here to show it fits the allowed grammar types when verifying tense usage. Grammar problem type ID:6

× And nowadays many people, umm, take car inside, ride a bicycle because, uh, at the speed the bicycle is slower and the.

✓ Nowadays many people drive cars instead of riding bicycles because cars are faster than bicycles.

Multiple issues: 'take car inside' is incorrect preposition and verb choice; correct collocation is 'drive cars' or 'take a car'. 'Ride a bicycle' is fine but needs contrast with 'drive cars instead of riding bicycles'. The fragment 'at the speed the bicycle is slower and the.' is ungrammatical and incomplete. The corrected sentence clarifies the contrast and uses correct comparative structure 'cars are faster than bicycles.' This addresses preposition/verb collocation errors (use 'drive' for cars), sentence structure and completion, and incorrect comparison formation. Suggestion: use clear collocations (drive a car, ride a bicycle), and form comparisons as 'X is faster than Y.' Grammar problem type ID:11
