Did you have a bike when you were a child?
점수: 58.0제안: Be careful with grammar and clarity. Start with a direct topic sentence, use correct tense and contractions, and avoid unnecessary details that don't answer the question. Add one concise supporting detail using a linking word. For example, correct the tense and wording (‘it was stolen’), and avoid continuing with irrelevant present-tense speculation about finding it unless it adds useful information.
예시: Yes, I did. I had a small red bicycle when I was about eight, but it was stolen when I was ten. As a result, I stopped riding outside for a while.
Do you think bikes are popular in your country?
점수: 64.0제안: Provide a clear direct answer, then support it with one or two specific reasons using linking words. Avoid general statements and repetition; use appropriate vocabulary (countable/plural form: ‘bicycles’).
예시: Not really; bicycles are not very popular in my country because there are few bike lanes and traffic makes cycling unsafe. However, I believe bicycles are useful and healthy, so the government should invest in cycling infrastructure to encourage more people to ride.
× I had a bike when I was a child but it's was stolen and I haven't found it yet.
✓ I had a bike when I was a child, but it was stolen and I haven't found it yet.
The error involves an incorrect auxiliary 'it's' combined with past tense 'was' producing 'it's was', which is ungrammatical. This is a past tense issue because the action of stealing occurred in the past. Correction: remove the unnecessary contraction 'it's' and use the simple past 'it was stolen'. Also add a comma before 'but' to join the clauses correctly. Suggestion: when describing completed past events use simple past (subject + past verb) without inserting extra auxiliaries.

✓ No, I don't think bikes are popular in my country, but I think they are really useful and people should ride bicycles because it is really healthy.
There are pronoun and tense/number consistency issues here. 'Bikes' is plural, so referring back with 'it's' (it is) is incorrect; use 'they are' to match plural. This is classified as a present tense issue because the speaker is making a general present-time statement; subject-verb agreement with plural subjects must use plural verbs. Also, the sentence runs on with multiple clauses; replacing the second 'and' with 'because' clarifies the causal relationship. Suggestion: ensure pronouns agree in number with their antecedents (bikes -> they), use present simple for general truths (they are useful; it is healthy), and break or connect clauses clearly to avoid run-on sentences.
