Bike— Part 1 채점 보고서

제안: 回答直接，但时态错误。问题询问过去的经历，应使用一般过去时“had”，而不是现在完成时“have”。建议先明确回答，再补充一个具体细节，例如骑车的年龄、用途或地点，使答案更完整。

예시: Yes, I had a bike when I was a child. I got it when I was about seven and often rode it around my neighborhood with my friends.

제안: 回答的核心意思正确，但主谓和代词不一致：bikes是复数，应使用“They’re very popular”，而不是“It’s”。此外，答案过于简短，建议说明流行的原因，并加入具体场景或人群，例如学生骑车上学、城市有自行车道等。

예시: Yes, bikes are very popular in my country. Many people use them for exercise and short trips, especially in cities where cycling is convenient and environmentally friendly.

× Yes, I have.

✓ Yes, I did.

问题是时态不一致。考官使用了过去时“Did you have...”，所以回答也应使用过去时助动词“did”，而不能使用现在完成时中的“have”。回答过去时一般疑问句时，可以用“Yes, I did.”。

× Yes, it's very popular.

✓ Yes, they are very popular.

“bikes”是复数名词，因此不能用单数代词“it”和单数动词“is”来指代。应使用复数代词“they”和复数动词“are”。建议先确认所指名词是单数还是复数，再选择相应的代词和谓语动词。
