Bike— Part 1 채점 보고서

제안: Sửa lỗi ngữ pháp căn bản: dùng thì quá khứ đơn đúng (I had), động từ và danh từ đúng (bike không phải buy), và chủ-động từ phải hòa hợp (I was -> I was/ I tried). Trả lời nên có câu chủ đề rõ ràng và 1–2 câu bổ sung ngắn gọn, mạch lạc, dùng liên từ nếu cần. Ví dụ nêu thời gian, ai tặng hoặc bạn dùng nó để làm gì để cụ thể hơn.

예시: Yes, I had a bike when I was a child. My parents bought it for me when I was seven, and I used it to ride to my friend’s house every afternoon.

제안: Cải thiện tính tự nhiên và chi tiết: trả lời trực tiếp sau đó nêu lý do cụ thể và một ví dụ/ngữ cảnh. Dùng liên từ (because, so, for example) và danh từ số đếm/định lượng khi cần (many people, in cities). Chú ý dùng mạo từ và danh từ đúng (a convenient vehicle -> a convenient mode of transport) và tránh lặp từ.

예시: Yes, I do. Bikes are quite popular in my country because they are cheap and convenient for short trips in busy cities. For example, many people use bicycles to commute to work or to run quick errands.

× Yes, I had a buy when I were try.

✓ Yes, I had a bike when I was a child.

The original sentence has multiple structural and word-choice errors. 'buy' is the wrong word; the correct noun is 'bike'. 'I were' is incorrect subject-verb agreement for singular first person in past tense; it should be 'I was'. 'try' is incorrect and seems to be a mistaken word for 'child' in this context. The corrected sentence matches the examiner's past-time question. Suggestion: Use the correct vocabulary (bike, child) and the past form of 'to be' for singular subjects ('I was').

× I think yes, because bikes are convenient vehicle.

✓ I think so, because bikes are a convenient means of transport.

The phrase 'convenient vehicle' is ungrammatical because 'vehicle' is a countable noun and needs an article ('a convenient vehicle') or a plural form. In context, a more natural expression is 'a convenient means of transport' or 'a convenient form of transport'. Also 'I think yes' is awkward; 'I think so' is idiomatic when agreeing. Suggestion: Use appropriate articles with countable nouns and prefer natural collocations like 'means of transport' or 'form of transport'. Grammar problem type ID:14
