Bike— Part 1 Báo cáo

Gợi ý: Give a slightly longer, natural response that directly answers and then adds one brief reason or detail. Keep it concise (no more than 3–4 short sentences) and use linking words like 'because' to connect ideas. Also avoid abrupt, one-word answers when possible.

Ví dụ: No, I didn't have a bike when I was a child because my family lived in a small apartment and there wasn't enough space to store one. However, I often played on scooters with my friends in the neighborhood, which was almost as fun.

Gợi ý: Make the answer more coherent and natural by using a clear topic sentence, linking words, and specific supporting details. Avoid short, choppy sentences and fillers like 'they are.' Provide an example or reason (e.g., cost, traffic, culture) and use vocabulary like 'cost-effective' or 'environmentally friendly.'

Ví dụ: Yes, bikes are very popular in my country because they are cost-effective and convenient for short trips. For instance, many people cycle to work to avoid traffic, and cities have dedicated bike lanes which makes cycling safer and more practical.

× Yes, I think bikes are very popular in our country. Many people use them and they are.

✓ Yes, I think bikes are very popular in our country. Many people use them and they are common.

The original second sentence fragment 'and they are.' is incomplete and lacks a noun or adjective to complete the idea, causing a sentence structure error (ID 26). Completing the sentence with an adjective like 'common' or 'popular' fixes the fragment and conveys the intended meaning. Suggestion: always ensure that a coordinate clause after 'and' includes a subject and predicate or a clear adjective/noun to complete the thought. Grammar problem type ID: 26

× These are very economic to use.

✓ They are very economical to use.

The adjective 'economic' describes the economy or production, while 'economical' describes something that saves money or is cost-effective. The student used 'economic' incorrectly, so this is an incorrect use of adjectives/adverbs (ID 13). Replace with 'economical' to accurately convey cost-efficiency. Also 'These' is better replaced by 'They' to refer back to 'bikes' smoothly. Suggestion: use 'economical' for cost-saving descriptions and 'economic' for matters relating to the economy.
