Bike— Part 1 채점 보고서

제안: Your answer is grammatically incorrect, too short, and not natural. Use past tense for a childhood question, give a brief topic sentence, then one or two supporting details using a linking word. For example, say you didn’t have a bike and explain why or what you used instead. Keep it under five sentences.

예시: No, I didn’t have a bike when I was a child because my family couldn’t afford one. However, I often walked to school and sometimes borrowed my friend’s bike on weekends.

제안: The reply is overly brief and grammatically incomplete. Provide a full sentence and add specific supporting details using linking words (e.g., because, therefore, however). Mention where and among whom bikes are popular, and give one reason or example. Keep it concise and natural.

예시: Yes, I think bikes are quite popular in my country, especially in cities and among students, because they are cheap and convenient for short trips. For instance, many university students cycle to campus to avoid traffic and save money.

× No, I don't have.

✓ No, I didn't.

The question 'Did you have a bike when you were a child?' is in the past simple. The student's reply should use past tense. 'I don't have' is present tense and incorrect for a past situation. Use 'I didn't' (short for 'I did not') to match past simple. Alternatively, 'No, I didn't have one.' is also clear and complete.

× I do.

✓ Yes, I think they are.

The question 'Do you think bikes are popular in your country?' expects an opinion in the present. The student's reply 'I do' is grammatically possible but sounds incomplete because the question asks about bikes being popular. A clearer reply is 'Yes, I think they are.' which uses present tense and explicitly references 'bikes'. If the intention was a short affirmative, 'Yes, I do' could work only if the verb in the question was 'Do you like bikes?' but here the better short answer is 'Yes, I think so.'.
