Bike— Part 1 채점 보고서

제안: 句子有语法、时态和重复错误，回答较长且有未完成部分。建议：1) 使用清晰的主句回答问题（例如：No, I didn't.）。2) 用一到两句补充具体细节，注意时态一致（past simple）。3) 删除重复词并完成未说完的内容。4) 使用连接词使逻辑更顺畅（for that reason / so / however）。示例改进点：将“I remember once I really wanted a bike at age 9 but my parents in.” 修改为完整句子并说明结果。

예시: No, I didn't. My parents thought cycling was too dangerous for me, so I usually walked to school or took the bus with my older sister. I remember wanting a bike when I was nine, but my parents refused because they worried about traffic, so I never got one.

제안: 语法和主谓一致有错误，句子较短且细节不足。建议：1) 使用正确的主谓一致（bikes are）。2) 给出具体原因和例子以丰富内容（例如：cost, traffic, environment）。3) 使用连接词连接观点和原因（because / therefore / for example）。4) 保持回答在3到4句内，避免重复。

예시: Yes, I think bikes are very popular in my country because they are cheap and convenient in crowded cities. Many people cycle to work to avoid traffic and save money, especially in smaller towns where public transport is limited.

× I didn't have a bike when I was a child because my parents thought it was too dangerous for me to ride along, so I usually walk to school or took the bus with my older sister.

✓ I didn't have a bike when I was a child because my parents thought it was too dangerous for me to ride alone, so I usually walked to school or took the bus with my older sister.

句子中描述的是过去的情况，主句已使用过去时（didn't have, thought），因此后面的动作也应使用过去时。原句中混用了现在时态“walk”和过去时“took”，时态不一致。建议将“walk”改为过去式“walked”。另外，“ride along”用法不当，应改为“ride alone”表示独自骑。

× I remember once I really want to wanted a bike at age age 9 but my parents in.

✓ I remember once I really wanted a bike at age 9, but my parents said no.

原句中有多处问题：动词时态混用（remember引出过去回忆，内部应使用过去式“wanted”），且出现重复单词“age age”。句末不完整“my parents in.”没有表达完整意思，推测想说父母不同意，可改为“my parents said no”或“my parents didn't agree”。建议删除重复词并将句子补充完整，时态统一为过去式。

× I think bikes is very popular in my country.

✓ I think bikes are very popular in my country.

主语是复数“bikes”，谓语动词应与复数主语一致，使用复数形式“are”而不是“is”。这是主谓一致错误（Subject-verb agreement）。

× In my country we usually need bike to go to work.

✓ In my country we usually need a bike to go to work.

可数名词“bike”在泛指单个时需要不定冠词“a”，或者用复数形式“bikes”表示普遍现象。原句缺少冠词导致不自然。建议根据想表达的意思选择“a bike”或“bikes”；若指一般需要骑自行车去上班，可改为“We usually need bikes to go to work.”
