Bike— Part 1 Báo cáo

Gợi ý: 回答的第一句直接回答了问题，但“That bike is growing”表达不自然，也无法清楚说明自行车的情况。可以改为“I had a bike when I was a child”，然后补充自行车的颜色、使用情况或骑车的地点。注意使用过去时，并用一个具体细节扩展答案。

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

Gợi ý: 答案的观点基本清楚，但“Yes, I think”搭配不完整，而且“That is very popular”中的“That”指代不明确。建议直接说“Bikes are very popular in my country”，并补充一个具体原因或例子，例如人们骑自行车通勤、锻炼或避免交通拥堵。

Ví dụ: Yes, bikes are quite popular in my country, especially among young people. Many people use them for exercise or short trips because they are convenient and environmentally friendly.

× Yes. That bike is growing.

✓ Yes. That bike was growing.

问题发生在过去，回答应使用过去时。将 is 改为 was，使时态与问题 “Did you have...” 保持一致。注意：从语义上看，bike 通常不会使用 growing；但根据要求这里只纠正时态，不改变词义。

× That is very popular.

✓ They are very popular.

前文的问题谈论的是复数名词 bikes，因此不能使用表示单数事物的代词 that。应使用复数代词 they。建议先判断所指名词是单数还是复数，再选择正确的代词。

× That is very popular.

✓ They are very popular.

主语 they 是复数，所以 be 动词应使用 are，而不是 is。使用 be 动词时，要根据主语的人称和单复数选择 am、is 或 are。
