Bike— Part 1 채점 보고서

제안: 回答直接但过于简短且信息量有限。可在保持自然的同时加入一到两句具体细节（如骑车的场合、喜欢的原因或与谁一起），并使用连接词使句子更连贯。同时注意避免重复信息（如“when I was a child”与“I had a bike”可更自然表达）。

예시: Yes, I did. I had a small red bike that I often rode around my neighborhood with my friends. Because the area was safe, we usually cycled to the park every afternoon, which helped me build confidence and enjoy outdoor activities.

제안: 回答观点明确但措辞有些重复（“popular”和“many people”意思接近）。建议给出更具体的支持理由或例子（如通勤、锻炼、政策或城市环境），并使用连接词（e.g., because, for example, therefore）来组织信息，使回答更充实且逻辑清晰。

예시: Yes, I think so. Bicycles are widely used for short-distance commuting and exercise, especially in cities with many bike lanes. For example, many people cycle to work or school because it's cheap and good for fitness, and local governments often promote cycling by improving infrastructure.

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

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

这句话语法正确。时态与提问（过去）一致，主谓结构完整，无数、代或介词使用错误。无需修改。

× Yes, I think many people in my country like riding bikes because it is very popular and healthy.

✓ Yes, I think many people in my country like riding bikes because they are very popular and healthy.

问题类型：12（代词使用错误）。原句中用单数代词“it”指代复数名词“bikes”与“many people”的概念不一致。建议使用复数代词“they”来指代“bikes”（或“cycling”）。此外，也可改为使用不可数名词短语“cycling is very popular and healthy”，即“cycling”作为整体活动用单数“it”或直接说“it is”。简明建议：当指代复数名词时用复数代词（they/them）；当指代活动或概念（不可数）时用 it。
