Bike— Part 1 채점 보고서

제안: 回答直接且语法基本正确，但只是重复题目，没有提供具体细节。可以补充自行车的颜色、用途，或一次相关的经历，让回答更自然、更充实。

예시: Yes, I did. I had a small blue bike when I was about eight, and I often rode it around my neighborhood with my friends.

제안: 回答表达了自行车受欢迎的原因，但“it”与复数名词“bikes”不一致；“ride back”用法不正确，应说“ride bikes”。可以补充具体人群或场景，并用连接词说明环保这一原因。

예시: Yes, bikes are quite popular in my country, especially in cities. Many people ride them for short trips because cycling is affordable and helps reduce air pollution.

× Yes, it is popular in my country and many people ride back to protect the environment.

✓ Yes, they are popular in my country and many people ride back to protect the environment.

“Bikes”是复数名词，因此后面应使用复数代词“they”，并搭配复数动词“are”，不能用单数代词“it”和单数动词“is”。
