Bike— Part 1 Báo cáo

Gợi ý: 回答直接，但时态错误：问题使用过去时“Did you…”，应回答“Yes, I did.”。可以补充一条具体信息，例如自行车的颜色、用途或骑车的地点，让回答更完整。

Ví dụ: Yes, I did. I had a small blue bike, and I often rode it around my neighborhood.

Gợi ý: 注意主谓一致和代词指代：“bikes”是复数，应说“They’re popular”，后文也应使用“They”或“bikes”，而不是“it”。“I always see it in my college”不够自然，可以说“我经常在校园里看到学生骑自行车”，并补充原因或具体场景。

Ví dụ: Yes, I think bikes are quite popular in my country. I often see students riding them around my college campus, especially when they’re going to class.

× Yes, I have.

✓ Yes, I did.

问题中的问句使用一般过去时助动词“Did”，回答时应使用对应的助动词“did”，而不是现在完成时助动词“have”。回答过去时的一般疑问句时，可以用“Yes, I did.”

× Yes, it's popular. I always see it in my college.

✓ Yes, they are popular. I always see them at my college.

“bikes”是复数名词，因此应使用复数代词“they”和“them”，不能用单数代词“it”。此外，“bikes”是复数，系动词也应使用“are”。
