Do you think bikes are popular in your country?
考生
Yes, they are popular because most of the time people use it for transportation, going to school, going to any destination. It's much easier and less stressful for them, less traffic.
Did you have a bike when you were a child?
分数: 45.0建议: Use the past tense because the question asks about your childhood: say “Yes, I did.” Add one brief, specific detail, such as how you used the bike or where you rode it.
示例: Yes, I did. I had a small red bike and used to ride it around my neighborhood after school.
Do you think bikes are popular in your country?
分数: 60.0建议: Your answer gives a relevant reason, but use “them” to refer to bikes and avoid repeating “going to.” Explain more clearly how cycling helps people, and connect your ideas with a linking phrase such as “for example” or “as a result.”
示例: Yes, bikes are quite popular in my country, especially in cities. Many people use them to commute to school or work because they are affordable and easy to park. As a result, cycling can also help people avoid traffic.
× Yes, I do.
✓ Yes, I did.
The question asks about a past situation using 'Did you have...?' The answer should also use the past-tense auxiliary 'did' rather than the present-tense auxiliary 'do'.
× Yes, they are popular because most of the time people use it for transportation, going to school, going to any destination.
✓ Yes, they are popular because most of the time people use them for transportation, going to school, and going to other destinations.
The pronoun 'it' is singular, but it refers to 'bikes,' which is plural. Use the plural pronoun 'them' to agree with its antecedent. 'Other destinations' also makes the list sound more natural.
× It's much easier and less stressful for them, less traffic.
✓ It's much easier and less stressful for them, and there is less traffic.
The phrase 'less traffic' is not a complete clause as written, so it does not connect grammatically to the preceding clause. Add 'there is' to form a complete clause and use 'and' to connect the ideas.
