自行车— Part 1 评分报告

建议: “I held back”在这里意思不清楚，也没有直接说明你小时候有没有自行车。请先明确回答有或没有，再补充一项具体信息，例如自行车的颜色、骑车的地点或使用频率。

示例: Yes, I did. I had a small red bike, and I used to ride it around my neighborhood with my friends.

建议: 回答时注意主谓一致：bikes 是复数，应使用“they are”。第二句中的“bag”与问题不相关，可能想表达“bike”；请用一个具体原因或例子说明自行车为什么受欢迎。

示例: Yes, bikes are very popular in my country. Many children ride them to school because they are affordable and convenient.

× Yes, it's very popular in my country.

✓ Yes, they're very popular in my country.

这里的代词指代前文复数名词“bikes”，因此应使用复数代词“they”，而不是单数代词“it”。
