Bike— Part 1 채점 보고서

제안: 句子有语法和用词错误，建议注意时态和主谓一致，并把回答扩展为一到两句以提供更多细节。例如使用简单过去时并说明自行车的类型或回忆。避免重复单词并保持言语自然。

예시: Yes, I did. I had a small blue bicycle with training wheels when I was about six, and I used to ride it around my neighborhood every weekend.

제안: 回答太简短，缺乏支持细节。建议用一到两句补充理由或例子，使用连接词使回答更连贯，例如说明在哪些人群或城市更常见，以及原因。

예시: Yes, they are very popular, especially in cities where many people cycle to work because it's cheap and convenient, and there are also many bike-sharing programs available.

× Yes, I did. I have a back when when I were a child.

✓ Yes, I did. I had a bike when I was a child.

句子中存在多处时态和词形错误： 1) “have” 用于一般现在时，但上下文是过去时（回答“Did you have...?”），应使用过去式 “had”。 2) 单词拼写错误 “back” 应为 “bike”。 3) 重复单词 “when when” 应删去一个。 4) 主语“ I ” 后面动词用于过去时应为 “was” 而不是 “were”（第一人称单数过去式用法）。 改进建议：根据上下文使用一致的过去时态，注意常见名词拼写并检查重复词。可多做过去式和常见词拼写练习，例如把一般现在时的动词变为过去式（have→had），并复习 be 动词过去式（I/he/she/it was, we/you/they were）。
