Bike— Part 1 채점 보고서

제안: 回答简单但有语法或用词错误，影响沟通。首先要直接回答问题并用正确词汇（bike 而非 back）。然后给出一到两句具体细节，如什么时候得到、谁送的或经常骑去哪里，使用连接词保持连贯。回答应控制在最多五句内。

예시: Yes, I did. I got my first bike when I was about seven, and my father taught me how to ride it in the park. After that I rode it almost every day to visit friends and explore the neighborhood.

제안: 回答过于简短且缺乏支持细节。应该先给出明确立场，然后用一到两句具体理由或例子支持，比如提到共享单车、健身或交通拥堵中骑行的普及。使用连接词（because, for example）使回答更连贯。

예시: Yes, I think bikes are very popular because many people use them for short trips and exercise. For example, in cities there are numerous bike-sharing programs and dedicated bike lanes that make cycling convenient and safe.

× Yes, I had a back.

✓ Yes, I had a bike.

虽然这条句子语法结构（主语+动词+宾语）是正确的，但“back”是错误的词汇，用来表达“自行车”应使用“bike”。这属于用词错误，不在你给出的具体问题类型列表中，但必须纠正以保证句意正确。建议：注意听清发音并记住常见名词拼写和词义，写作时可对照词典核对单词。

× Yes, I think so.

✓ Yes, I think so.

该句语法正确，回答与前问“Do you think bikes are popular in your country?” 时态和用法都合适（一般现在时表达一般看法）。无需修改。
