Bike— Part 1 채점 보고서

제안: 回答应更完整，有主题句并提供具体细节以展示流利度与内容深度。可以加入年龄、使用频率、用途或记忆等细节，并使用连接词使句子更自然。避免过于简短的“Yes”。

예시: Yes, I did. I had a red bicycle when I was about eight, and I rode it almost every day to visit my friends and explore the neighborhood. It was my main way of getting around, and I remember learning to ride without training wheels one summer, which felt like a big achievement.

제안: 注意语法（主谓一致：‘bikes are’），并提供更具体的理由或例子支撑观点，例如在哪些地区更常见、为什么受欢迎、使用场景等。同时用连词使回答更连贯，避免单一句子回答。

예시: Yes, I think bicycles are quite popular in my country, especially in cities and university towns, because they are cheap, convenient and eco-friendly. For instance, many people use bikes for short commutes to work or school, and cities have been adding bike lanes to encourage cycling.

× Yeah, bikes is popular in our country.

✓ Yeah, bikes are popular in our country.

语法问题类型 ID：27（主谓一致错误）。 解释（简体中文）：原句中主语是复数名词“bikes”，谓语动词用的是单数形式“is”，与主语不一致。英语中复数主语应使用复数动词形式“are”。建议：判断主语是单数还是复数，若为复数（如 bikes、cars、students 等），谓语用复数形式（are、have、do 的复数形式等）；若为单数则用单数动词（is、has、does 等）。
