Did you have a bike when you were a child?
分數: 72.0建議: Be more natural and concise. Start with a direct short answer, then add one or two specific supporting details (briefly) using a linking word. Avoid repeating auxiliary verbs. Keep within 2–3 sentences.
範例: Yes, I did. I had a red bicycle that I used to ride to my friend’s house every weekend, and I practiced riding in the park until I felt confident.
Do you think bikes are popular in your country?
分數: 80.0建議: The answer is relevant but can be improved by adding a specific example or brief explanation using a linking phrase. Use slightly more varied vocabulary (e.g., ‘common’ or ‘widely used’) and avoid contraction of ideas into one clause—give a supporting reason or example in a second sentence.
範例: Yes, bikes are very popular in my country because they are inexpensive and easy to maintain. For example, many people use bicycles to commute short distances in cities, especially during rush hour.
× Yes, I did have a bike when I was a child.
✓ Yes, I had a bike when I was a child.
This sentence uses an unnecessary auxiliary 'did' with the past simple affirmative. In affirmative past tense, use the past form of the verb without 'did' (subject + past verb). Suggestion: remove 'did' and say 'I had' to make the sentence grammatically correct and more natural.
× Yes, I do think bikes are very popular in my country because it's the most accessible mode of transportation.
✓ Yes, I think bikes are very popular in my country because they are the most accessible mode of transportation.
The original uses 'do' as an emphatic auxiliary which is not incorrect but unnecessary in a simple statement; this matches present tense usage but is optional. More importantly, 'it's' (it is) incorrectly refers to 'bikes' (plural). Use the plural pronoun 'they are' to agree with 'bikes'. Also 'do' can be omitted for a natural response: 'I think'. Suggestion: remove 'do' unless emphasizing, and change 'it's' to 'they are' for subject-pronoun agreement.
