Bike— Part 1 채점 보고서

제안: 回答直接，也提供了年龄、购买者和用途等具体信息，内容基本完整。但“the dad”应改为“my dad”，“the dad bought it”时态和表达不够自然；句末应加句号。可以使用“because”或“so”连接细节，使逻辑更流畅。

예시: Yes, I had a bike when I was seven. My dad bought it for me, and I used to ride it to school every day. It was a simple bike, but I really enjoyed riding it.

제안: 回答了“是”，但后半部分存在明显的词汇和重复问题。“backer”不是此处合适的词，应使用“bikes”或“cyclists”；“I can see...”和“I usually see...”重复，且没有解释自行车为什么受欢迎。建议加入具体原因，例如价格便宜、方便、环保，或举出现实中的例子。

예시: Yes, bikes are quite popular in my country. I often see people riding them on the roads, especially in big cities. They are affordable, convenient, and environmentally friendly, so many people use them for commuting.

× Yes, when I was seven years old the dad bought it for me and I used it to go to school.

✓ Yes, when I was seven years old, my dad bought it for me, and I used it to go to school.

“dad”前面不应使用定冠词“the”，因为这里指的是“我的爸爸”，应使用物主限定词“my”。另外，在时间状语从句后加逗号，可以使句子结构更清晰。

× Yes, I can see the backer I usually see the backer on the road.

✓ Yes, I usually see bikers on the road.

这里是在泛指路上的骑自行车的人，所以应使用复数“bikers”，而不是单数形式。原句还重复使用了“I can see the backer”和“I usually see the backer”，应删去重复部分。
