Bike— Part 1 채점 보고서

제안: 句子时态和用词不准确，导致表达不自然。回答应直接回应问题并简洁说明过去拥有自行车的情况，建议使用过去时并补充一两句具体细节（如谁送的、经常在哪儿骑或学会骑的年龄）。保持不超过5句并使用连接词使叙述流畅。

예시: Yes, I did. I got a small red bike when I was about five or six, and my father helped me learn to ride it in the park. I used to ride it almost every day after school, which helped me become more confident and active.

제안: 回答逻辑混乱且有语法错误。先给出明确观点（Yes/No/both），然后用一到两句具体解释并用连接词衔接原因或对比。注意时态和单复数，避免矛盾表述（例如先说“No”再说“was popular”）。

예시: They used to be very popular, but nowadays electric bikes are much more common. In many cities people prefer electric bikes because they are faster and easier for commuting, so traditional bicycles are less seen on the streets.

× Yes, I have a bike at the moment when I was about 5 or 6 years old.

✓ Yes, I had a bike when I was about 5 or 6 years old.

语法问题类型 ID: 6（现在时问题）。学生在描述过去拥有事物时错误地使用了现在时（have），而句子后半使用了过去时间状语“when I was about 5 or 6 years old”，时态应一致使用过去时。建议把动词改为过去式 had，完整句子与时间状语保持一致："I had a bike when I was about 5 or 6 years old."。

× No, it was popular in my country. I'm in China now that the electric bike everywhere.

✓ No, they are popular in my country now. I'm in China and electric bikes are everywhere.

语法问题类型 ID: 6（现在时问题）。原句有多处时态和结构错误：1) "No, it was popular" 用单数代词 it 指代复数名词 bikes，且用过去时与现在情况不符；应使用复数主语和现在时 are。2) "I'm in China now that the electric bike everywhere" 结构混乱，缺少谓语动词，且复数名词形式不对。建议改为两句："They are popular in my country now."（使用复数和现在时）和 "I'm in China and electric bikes are everywhere."（补上连词 and，使用现在时并将 bike 改为复数 bikes）。
