Bike— Part 1 채점 보고서

제안: Your answer is clear and relevant, but could be more natural and concise. Start with a direct topic sentence, then add one or two specific supporting details. Correct grammar (past ability) and avoid repetition. Use linking words for coherence (for example, because or so).

예시: Yes, I did — I used my dad’s bike when I was a child. It was much too large for me, so my feet couldn’t touch the ground, which made me wobble a lot at first.

제안: Good main idea but the answer has grammar errors, filler words (uh), and some unclear phrasing. Use a clear topic sentence, reduce hesitations, and provide specific reasons/examples with correct tense and linking words (for example, because, since, therefore).

예시: Yes, bikes are popular for short commutes. However, in recent years shared-bike schemes have become more common because they are convenient to pick up and leave anywhere; as a result, fewer people own private bikes now.

× Yes, I had a bike before.

✓ Yes, I had a bike when I was a child.

The original sentence 'Yes, I had a bike before.' is grammatically acceptable but is vague. The examiner's question refers to childhood, so use past time expression 'when I was a child' to match context and make the time reference clear. Use the simple past 'had' correctly for a past possession.

× It was my dad's bike.

✓ It was my dad's bike.

This sentence is already correct. It uses the possessive form 'dad's' appropriately. No change needed.

× I still remember it very clearly because it was very big for me and my leg cannot reach the ground.

✓ I still remember it very clearly because it was very big for me and my legs could not reach the ground.

Two issues: 'my leg cannot reach the ground' mixes present tense with a past story and uses singular 'leg' although both legs are usually meant; this is a tense and number mismatch. Change 'cannot' to past 'could not' to match the past narrative and 'my legs' to plural for natural expression. This addresses present/past tense consistency and subject-verb agreement/number.

× Yes, it is a popular choice for commute uh, but nowadays, uh, shared bike is more popular than private bike because you can take it anywhere and uh, park it anywhere.

✓ Yes, it is a popular choice for commuting, but nowadays shared bikes are more popular than private bikes because you can take them anywhere and park them easily.

Several problems: 'choice for commute' uses wrong form; use the gerund 'commuting'. 'shared bike' and 'private bike' need plural 'shared bikes' and 'private bikes' when speaking generally. Also pronouns should agree: 'you can take them' rather than 'it'. 'park it anywhere' is informal; 'park them easily' sounds natural. These are present tense general statements, so simple present is correct.

× People start using shared bike since several years ago and now there's rarely private bikes.

✓ People started using shared bikes several years ago, and now there are hardly any private bikes left.

'People start using' is incorrect because the action began in the past; use simple past 'started'. 'since several years ago' is redundant; use 'several years ago' or 'since' with a specific point. 'there's rarely private bikes' has agreement and word choice errors: 'there are' for plural, and 'rarely' is adverb not ideal—use 'hardly any' to indicate scarcity. Also pluralize 'shared bikes' and 'private bikes' to match general reference.
