自行车— Part 1 评分报告

建议: 先直接回答过去是否拥有自行车，并使用过去时：把“have”改为“had”，把“back”改为“bike”。可以补充一个具体细节，例如自行车的颜色、骑车的地点或用途，让回答更完整。

示例: Yes, I had a bike when I was a child. It was red, and I often rode it around my neighborhood.

建议: 你的回答没有清楚说明自行车是否受欢迎；“it's cleaning”在这里表达不自然。可以先明确回答“很受欢迎”或“不太受欢迎”，再说明一个具体原因，例如骑车通勤方便、费用低或有利于环保。

示例: Yes, I think bikes are quite popular in my country because they’re an affordable and convenient way to get around. Many people also ride them to work or school.

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

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

句子中的“when I was a child”表示过去的时间，因此“have”应改为过去式“had”。“back”属于用词或转写问题，不在指定的语法问题类型范围内，所以这里不作修改。
