Bike— Part 1 採点レポート

提案: Your answer is very short and lacks a topic sentence with supporting details. To improve, give a clear direct response followed by 1–2 specific details (e.g., reasons, memories, or comparisons). Use a linking word to connect ideas and keep it natural and concise. Aim for 2–4 sentences total.

例: No, I didn't have a bike when I was a child. My family couldn't afford one, so I usually walked to school or took the bus; however, I remember sometimes borrowing my neighbor's bike to ride in the park.

提案: You answer the question but the response is brief and slightly unclear. Start with a clear opinion, then give specific supporting reasons or examples and use a linking word (e.g., because, although, however). Avoid vague phrases like "too expensive to afford" without context—explain who finds them expensive and why.

例: Yes, bikes are fairly popular in some areas, but not everyone can afford them because good-quality models are expensive and import taxes raise the price. For example, many people prefer motorbikes or public transport instead, especially in cities where traffic makes biking less practical.

× No, I didn't have.

✓ No, I didn't.

The student's response 'No, I didn't have.' is incomplete because the verb 'have' in negative past simple typically needs an object only when specific possession is clarified (e.g., 'I didn't have a bike'). In answer to 'Did you have a bike when you were a child?' the expected short negative answer is 'No, I didn't.' or the full answer 'No, I didn't have a bike.' Use 'No, I didn't.' for a complete, natural short response or include the object for clarity.

× Well, they are, but in our country they are too expensive to afford.

✓ Well, they are, but in our country they are too expensive to afford.

The sentence is grammatical, but the phrase 'too expensive to afford' is redundant because 'expensive' already implies cost; 'to afford' is a verb that needs a subject (e.g., 'for people to afford' or 'for us to afford'). A clearer phrasing would be '...they are too expensive for people to afford' or '...they are too expensive for us to afford.' However, since the instruction demands only correcting items from the provided Grammar_Problem_Type_List, identify the issue as incorrect use of quantifiers/phrasing and suggest replacing the phrase with 'too expensive for people to afford' to supply the missing logical subject.
