Bike— Part 1 채점 보고서

제안: 回答方向正确，也直接回答了问题，但时态错误：谈论童年经历应使用一般过去时，不能说 “I have” 和 “I am”，应改为 “I had” 和 “I was”。此外，第二句与第一句重复，可以加入一个具体细节或原因，使答案更自然、更丰富。

예시: Yes, I did. I had a bicycle when I was a child, and I often rode it around my neighborhood after school. It was a simple bike, but I really enjoyed riding it.

제안: 答案过于简短，而且缺少主语。应说 “Yes, they are popular” 或 “Yes, bikes are popular”。为了更完整地回答Part 1问题，可以补充流行的原因和具体使用场景，并使用 “because” 或 “especially” 等连接和补充表达。

예시: Yes, bikes are quite popular in my country, especially among students and young adults. Many people use them because they are convenient, affordable, and environmentally friendly.

× I have a bicycle when I am a child.

✓ I had a bicycle when I was a child.

问题出在过去时态。句子描述的是“小时候”的经历，应该使用一般过去时，因此将“have”改为“had”，将“am”改为“was”。回答过去经历时，要注意主句和时间从句中的动词都要保持过去时。

× Yes, is popular.

✓ Yes, they are popular.

问题出在代词使用。句子缺少主语，不能直接说“is popular”。因为问题中的主语“bikes”是复数，所以可以用复数代词“they”代替，并搭配复数动词“are”。
