Bike— Part 1 채점 보고서

제안: 你的回答比较自然且信息明确，但存在口头语（如“umm”）和重复（如多次停顿）影响流畅性；句子略长且结构不够紧凑，细节可以更具体（例如描述学会骑车的经历或父母为什么担心安全）。建议减少填充词，使用一到两句主题句并补充一至两条具体细节或一个简短原因，使总句数不超过五句。

예시: Yes. My parents bought me a bicycle when I was in primary school and taught me how to ride it. However, they didn’t let me cycle on the road until I was twelve because they worried about traffic and safety. I practiced in our courtyard every weekend, which helped me build confidence.

제안: 内容清晰并给出对比（过去与现在），但有重复词（“and and”）、非正式缩写（'cause）和语法小问题。可以用连接词使表达更连贯，加入具体例子或数据（如城市共享单车的兴起或你常见的骑行场景）来增强说服力。保持句子简洁，避免口语填充和重复。

예시: Yes. Historically many Chinese people used bikes to commute, but with the expansion of subways and buses, fewer people rely on personal bicycles. However, cycling remains popular for short trips and shopping because it’s cheap and convenient; for example, bike-sharing services are widely used in my city for quick errands.

× Yes, my parents gave me a bike when I was in primary school and they taught me how to ride UMM, but unfortunately I was not allowed to ride a bike until I was 12 years old umm, because of the safety problem.

✓ Yes, my parents gave me a bike when I was in primary school and they taught me how to ride, but unfortunately I was not allowed to ride a bike until I was 12 years old because of safety concerns.

句子中主要时态为过去时（gave, taught, was not allowed），时态使用正确。需改动的不是时态本身，而是去掉语气词“UMM/umm”和多余的定冠词“the”，并将“the safety problem”改为更自然的表达“safety concerns”。这些改动使句子更符合口语书面化表达。建议：说话时省略填充词（um/umm），并用更自然的短语（如 safety concerns 或 safety reasons）。

× Yes, in the past many Chinese people have their own bikes for going to work or school and now we have subways and buses.

✓ Yes, in the past many Chinese people had their own bikes for going to work or school, and now we have subways and buses.

原句中“in the past”提示应使用过去时，但用了现在完成时“have”。根据时间状语，要使用一般过去时“had”。建议：遇到明确的过去时间标志（in the past, last year 等）时，使用过去时。

× But cycling is still common and and still a convenient way for shop trips 'cause it's cheap.

✓ But cycling is still common and is still a convenient way for shopping trips because it's cheap.

句子存在“and and”重复，是口语填充错误；另外“shop trips”搭配不自然，改为“shopping trips”更常用；口语缩写“'cause”在书面或更正式回答中应写作“because”。本题归为句子结构/连词使用问题。建议：注意避免重复连词，使用正确名词短语（shopping trips），在正式语境使用完整连词“because”。
