Bike— Part 1 채점 보고서

제안: Your answer addresses the question but is unclear, wordy and contains grammar mistakes. Be concise: give a direct topic sentence, then one or two specific supporting details with correct tense and linking words. Avoid irrelevant or confusing information (for example, "took the university entrance examination" is unrelated here).

예시: I didn't have a bike as a child. I couldn't ride one until later, and my mother only showed me the basics. However, when I started middle school I began practicing so I could use a bike to get around campus.

제안: Good clear answer with relevant detail. To improve, expand slightly using linking words and a specific example or comparison, and vary vocabulary (e.g., "shared bikes", "solve the last-mile problem"). Keep responses natural and within 3–4 sentences.

예시: Yes, bikes are very popular in China. In particular, shared bikes have become widespread and help solve the last-mile problem for commuters. For example, many people ride a shared bike from the subway station to their office.

× My mom told me how to use a basic bicycle.

✓ My mom taught me how to ride a basic bicycle.

The original sentence uses 'told me how to use' which is grammatically acceptable but unnatural for learning a physical skill; 'teach' and 'ride' are the correct collocations. Change 'told me how to use' to 'taught me how to ride' to match expected verb usage and collocation.

× After I took the middle school, I took the university entrance examination because bicycle will be useful in universities.

✓ After I finished middle school, I took the university entrance examination because bicycles would be useful at university.

Multiple issues: 'took the middle school' is incorrect — use 'finished middle school' (sentence structure). 'I took the university entrance examination' is fine. 'bicycle will be useful in universities' has article/number and tense problems: use the plural 'bicycles' and modal/conditional 'would be useful' (future-in-past or intention) and 'at university' is the usual preposition. Corrections address sentence structure, article/number, preposition and tense/verb form.

× Here in China we use a lot of shared bikes which solve the last one mile issue of many people.

✓ Here in China we use a lot of shared bikes, which solve the last-mile problem for many people.

'last one mile issue' is awkward and unidiomatic; use the compound noun 'last-mile problem'. Also change 'of many people' to 'for many people' to use the correct preposition. Adding a comma before 'which' clarifies the nonrestrictive clause.
