Bike— Part 1 채점 보고서

× No, I don't have one.

✓ No, I didn't have one.

The question asks about possession in the past ('Did you have a bike when you were a child?'), so the student should use the past tense. 'Don't have' is present tense; the correct negative past form is 'didn't have'. Suggestion: use past simple for past situations, e.g., 'I didn't have one.'

× Yes, I think uh bikes are very common in children, adults, everyone loves them and I learn how to drive a bike when I am 15.

✓ Yes, I think bikes are very common among children and adults; everyone loves them, and I learned how to ride a bike when I was 15.

Multiple issues guided by the tense and preposition use: 'are very common in children, adults' should use the preposition 'among' to indicate groups. The personal experience 'I learn how to drive a bike when I am 15' refers to a past event, so it should be past simple: 'I learned' and 'when I was 15.' Also, 'drive a bike' is less natural than 'ride a bike.' Suggestion: use 'among' for groups, use past simple for past experiences, and use 'ride' with bicycles.
