Bike— Part 1 채점 보고서

제안: 回答直接，但时态错误。因为“when I was a child”指过去，应该把“have”改为过去式“had”。可以再补充一个具体细节，例如骑车的地点或用途，使答案更自然、更丰富。

예시: Yes, I had a bike when I was a child. I often rode it around my neighborhood after school, and I really enjoyed exploring the area with my friends.

제안: 回答了问题，但“every teenager have”存在主谓一致错误，应改为“every teenager has”。此外，“every”过于绝对，容易显得不准确；可以使用“many teenagers”或“quite popular”，并补充一个原因或具体场景。

예시: Yes, bikes are quite popular in my country, especially among teenagers. Many of them ride bikes to school or use them to meet friends because they are convenient and inexpensive.

× 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，因此主句中的动词也应使用一般过去时。“have”的过去式是“had”。建议看到“when I was...”等明确的过去时间表达时，检查主句动词是否需要改为过去式。

× Yes, I think every teenager have a bike.

✓ Yes, I think every teenager has a bike.

“every teenager”表示每一个青少年，语法上是单数主语，因此一般现在时中动词应使用第三人称单数形式。“have”应改为“has”。建议特别注意“every”后面的名词通常视为单数，并检查动词是否需要加“-s”或使用特殊形式。
