Bike— Part 1 채점 보고서

제안: 句子时态和主谓一致需要改进，回答应更直接并用一到两句说明细节，避免冗长和语法错误。可将过去时统一使用（例如：I had），并补充具体细节如骑车的经历或感受，使用连接词使逻辑更清晰。

예시: Yes, I had a bike when I was a child. My dad bought it for me when I was seven because he thought it was more convenient, and I used to ride it to visit friends every weekend.

제안: 内容较好但表达需更准确流畅。注意动词形式（例如: people riding → people riding their bikes 或 people who ride bikes），用连接词（for example, because）并举具体例子或比较来丰富答案。避免模糊词 like "maybe"。

예시: Yes, bikes are very popular in my country. For example, I often see commuters and students cycling to work or school because cycling is eco-friendly and much cheaper than using a car or public transport.

× I do have a bike when I was a child and I remember I have it when I was 7 and my dad bought me that because he says that it's more convenient.

✓ I had a bike when I was a child. I remember I had it when I was seven, and my dad bought it for me because he said it was more convenient.

句子谈论过去的情况，应使用过去时。原句中混用了现在时（do have, have, says）和过去时（was, bought），时态不一致。建议将所有描述过去的动词改为过去式，例如：do have → had，have → had，says → said；并将代词与名词搭配改为更自然的表达（bought me that → bought it for me）。

× Like if I can learn how to cycling also in the future I can cycle into school.

✓ For example, if I could learn how to cycle, then in the future I could cycle to school.

原句中“learn how to cycling”是动词后接动名词形式错误，应使用动词不定式或动词原形（learn how to cycle）。此外，句子表达假设和将来可能性时应保持时态一致（用could或can根据语境）。“cycle into school”习惯搭配为“cycle to school”。建议把结构改为条件句并统一时态。

× Yes, absolutely, because when I walk on the street I can see a lot of people who riding their bikes.

✓ Yes, absolutely. When I walk on the street, I can see a lot of people riding their bikes.

原句中“who riding their bikes”缺少关系从句的谓语动词，应使用现在分词或在从句中加动词（who are riding）。更自然的说法是直接用现在分词短语“people riding their bikes”。另外句子连接处可用句号分开以更清晰。

× So I think maybe it's because it's eco friendly and it's cheaper than other transport vehicles.

✓ So I think maybe it's because it's eco-friendly and cheaper than other means of transport.

“eco friendly”作为合成形容词应加连字符：eco-friendly。短语“other transport vehicles”冗长且不太地道，建议用“other means of transport”或“other modes of transport”。此外省略重复的主语和系动词使表述更简洁（and it's cheaper → and cheaper）。
