Bike— Part 1 Báo cáo

Gợi ý: Your answer is grammatically correct and directly answers the question, but it is very short and lacks supporting detail. To improve, add one or two specific supporting sentences explaining why you didn't have a bike (for example, family reasons, cost, or preference) and use a linking word to connect ideas. Keep the total to no more than 4–5 sentences and avoid repetition.

Ví dụ: No, I didn't have a bike when I was a child. My family couldn't afford one at the time, so I usually walked to school. However, I sometimes borrowed a friend's bike on weekends to ride in the park.

Gợi ý: Your answer addresses the question but has grammar and word-choice errors and is slightly vague. Improve by giving a clearer topic sentence, using correct verb forms, and adding a specific reason or example. Use linking words such as 'because' or 'for example' to make the answer coherent, and avoid repeating words.

Ví dụ: Yes, bikes are quite popular in my country, especially among teenagers. For example, many young people enjoy mountain biking because there are several nearby trails and it is an affordable way to stay active.

× Yes, bikes are popular in our country, especially to teenagers who wanted to to ride bikes in mountains.

✓ Yes, bikes are popular in our country, especially with teenagers who want to ride bikes in the mountains.

The phrase 'to teenagers who wanted to to ride bikes in mountains' contains several issues: (1) 'wanted' incorrectly uses past tense; the general statement about popularity requires present simple 'want' (Grammar Problem Type ID 6: Present tense issue). (2) 'to teenagers' is not the usual preposition; use 'with teenagers' (Grammar Problem Type ID 11: Incorrect use of prepositions). (3) 'to ride' after 'who want' requires the base form 'ride' without 'to' because relative clause uses 'want to ride' where 'to' is part of the infinitive; the original had an extra 'to' (Grammar Problem Type ID 8: Verb + -ing form or 9/10? but primarily fix is removing duplicate 'to'). (4) 'in mountains' lacks the article 'the' for specific mountains: use 'in the mountains' (Grammar Problem Type ID 17: Incorrect use of the definite article). Overall correction: 'especially with teenagers who want to ride bikes in the mountains.' Suggestions: use present simple for general truths (are popular / want), use 'with' to indicate a group, avoid duplicate particles like 'to to', and include 'the' before plural geographic nouns when referring to a known category ('the mountains').
