Bike— Part 1 Report

Suggestion: 回答没有准确回应过去的经历：“I have”是现在时，而且“back”不是“bike”。先用过去时直接回答，再补充一个具体细节，例如年龄、骑车地点或用途。

Example: Yes, I had a bike when I was a child. I used to ride it around my neighborhood after school.

Suggestion: 开头直接表达观点，但“bike bikes”重复了，“public”也不能表达“受欢迎”，这里应使用“popular”。回答后可以补充一个具体原因或例子，让内容更完整。

Example: Yes, bikes are quite popular in my country, especially in cities. Many people use them for short trips because they’re convenient and inexpensive.

× Yes, I have a back.

✓ Yes, I had a bike.

问题问的是你小时候“有没有”自行车，使用的是过去时，因此回答中应将现在时 have 改为过去时 had。这里的 back 也应为 bike；这是用词错误，不属于指定的语法问题类型，因此不单独标注。
