Bike— Part 1 채점 보고서

제안: 句子要更自然、语法正确并提供适当细节。注意冠词和时态（例如："when I was a child"），避免重复且可加一两句补充说明来丰富回答。可以在5句内用连接词承接细节。

예시: Yes, I had a bike when I was a child. It was a small red bicycle with training wheels, and I used to ride it around my neighborhood every afternoon. I learned to balance on it by practicing with my older brother, and soon I could ride without the training wheels.

제안: 回答需语法正确并提供具体原因或例子。修正主谓和时态错误（例如："almost everyone had a bike when they were a child"改为"when they were children" 或更自然的现在时）。使用连接词给出原因或对比，使回答更有说服力。

예시: Yes, bikes are very popular in my country because they are affordable and convenient for short trips. For example, many children learn to ride bikes to go to school or play with friends, and adults often use bicycles for commuting in crowded cities.

× Yes, I had a bike when I was child.

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

错误类型：单复数/冠词缺失。句中缺少不定冠词 a，正确表达为 "a child" 或使用复数/其他结构。建议：在表示某人作为儿童时，常用固定搭配 "when I was a child"。注意在类似结构中检查冠词使用。","grammar_problem_type_id":1},{
