Bike— Part 1 채점 보고서

제안: 回答过于简短且不相关，缺乏主题句和细节。你应直接回答问题，说明是否有自行车并给出一两条具体细节（例如什么时候有、用途或感受），用连接词使回答连贯。保持自然，控制在不超过5句内。

예시: Yes, I did. I got my first bike when I was seven and used it to ride to my friends' houses every afternoon. Because our neighborhood was quiet, I felt safe learning to ride there. In winter I hardly used it, but in summer I rode it almost every day.

제안: 回答太简短，未展开理由或例子。应先给出明确立场，然后用一到两句具体原因或例子支持观点，并使用连接词（for example, because, so）使信息连贯。控制句数，语言自然。

예시: Yes, bikes are quite popular in my country because many people use them for short commutes and exercise. For example, in big cities there are bike-sharing schemes and dedicated lanes, so cycling is convenient and affordable.

× Come on.

✓ Yes, I did.

原句“Come on.”在此情境中作为学生对“Did you have a bike when you were a child?”的回答并不合适，缺少动词和明确的肯定或否定意义，属于句子结构错误（无动词或不完整回答）。建议根据提问使用完整句子回答，如肯定用“Yes, I did.”，否定用“No, I didn't.”，以确保主谓明确并符合过去时态。

× Yeah.

✓ Yes, they are.

原句“Yeah.”作为对“Do you think bikes are popular in your country?”的回答过于简略，虽口语可接受但在正式测试应给出完整句子，包含主语和系动词，符合一般现在时。建议使用“Yes, they are.”或更详细的回答例如“Yes, I think bikes are very popular.”以使句子完整且语法正确。
