Bike— Part 1 Báo cáo

Gợi ý: 回答基本切题，但时态错误。由于问题询问过去经历，应使用一般过去时，例如将“have”改为“had”。同时，可以补充一个具体细节，如自行车的颜色、用途或骑车地点，使回答更完整、更自然。

Ví dụ: Yes, I had one when I was a child. It was a small blue bike, and I often rode it around my neighborhood after school.

Gợi ý: 回答过于简短，而且缺少主语和正确的系动词。应说“Bikes are very popular”，因为主语是复数。建议直接回答观点，然后补充一个原因或具体场景，例如人们骑自行车通勤、锻炼或短途出行。

Ví dụ: Yes, bikes are very popular in my country, especially among students and people who live in crowded cities. They are convenient and environmentally friendly.

× Yes, I have one.

✓ Yes, I had one.

问题出在时态。考官问的是“你小时候有自行车吗？”，其中“when you were a child”表示过去的时间，所以回答也应使用一般过去时。将“have”改为“had”。

× Is very popular.

✓ They are very popular.

这个句子缺少主语，因此句子结构不完整。问题中的主语是复数名词“bikes”，回答时可以用复数代词“They”代替；同时，主语是复数，所以系动词应使用“are”，不能使用“is”。
