自行车— Part 1 評分報告

建議: 回答直接，但时态错误。因为问题询问过去的经历，应将“have”改为过去式“had”。此外，可以补充一个具体细节，例如你何时骑车、在哪里骑车或骑车的用途，使答案更完整自然。

範例: Yes, I had a bike when I was a child. I often rode it around my neighborhood after school, and it was a fun way to spend time outdoors.

建議: 回答基本切题，但“it's”指代不清，且“bikes”是复数，应改为“They are very popular in China”或“Cycling is very popular in China”。“Many people ride a bike at night”范围较窄，建议说明骑自行车受欢迎的原因，并使用连接词使内容更连贯。

範例: Yes, bikes are very popular in China, especially in large cities. Many people ride them to work or school because cycling is convenient, affordable, and environmentally friendly.

× Yes, I have a bike when I was a child.

✓ Yes, I had a bike when I was a child.

“When I was a child”表示过去的时间，因此主句也应使用一般过去时。将“have”改为过去式“had”。建议根据时间标志词判断时态，例如“when I was a child”通常与一般过去时连用。

× Yes, it's very popular in China.

✓ Yes, they are very popular in China.

“Bikes”是复数名词，不能用单数代词“it”指代；应使用复数代词“they”。同时，复数主语要搭配“are”，所以改为“They are”。
