自行车— Part 1 評分報告

建議: 句子有语法和用词错误，表达也有些冗长。建议：1) 开头直接回答并用简单句明确时态（e.g. I did / I had）。2) 修正动词形式和非谓语结构（offer → offered；which → that 或用连词）。3) 用一到两句具体细节支持观点并使用连接词（for example, so, because）。4) 控制在最多5句内，避免重复信息。

範例: Yes, I did. My father bought me a bike when I was in primary school, and it really helped me socialize. For example, I often rode home with my classmates after school, which made our friendships closer.

建議: 内容混乱且大量词汇错误（bags/back？），语法不清晰。建议：1) 直接回答并给出两个清晰理由（environmental and cheap）。2) 用正确词汇（bikes, environmentally friendly, affordable）。3) 使用连接词使逻辑连贯（because, and, so）。4) 提供一具体例子或简单比较来支持观点。

範例: Yes, bikes are quite popular in my country because they are environmentally friendly and very affordable. For instance, many students cycle to school instead of taking buses, which reduces traffic and saves money.

× Of course, my father bought a bike for me when I was in primary school, which offer me a chance to socialize with friends.

✓ Of course, my father bought a bike for me when I was in primary school, which offered me a chance to socialize with friends.

原句中的 which 指代前面的整个事实（父亲买了自行车），而谓语动词用现在时的 offer 与主句过去时 bought 时态不一致，导致时态错误。应将 offer 改为过去式 offered，使从句与主句时态一致。建议：在描述过去发生的事情时，从句也应使用过去时。

× For example, I always ride back with friends after school.

✓ For example, I always rode back with friends after school.

句子在描述童年习惯，主句为过去时（when I was in primary school），but 使用现在时的 ride 与语境不符。应使用过去时 rode 来表示过去经常发生的动作。建议：谈论过去的习惯时用过去时（一般过去时或 used to）。

× Of course, because bags are environmentally friendly which provide a healthy air besides back is cost friendly, we can pay a low price to take this transportation to school.

✓ Of course, because bikes are environmentally friendly, which provide clean air, and bikes are cost‑friendly; we can pay a low price to use this mode of transportation to get to school.

原句存在多个问题：1) 将 bikes 错误写为 bags（词错误，但属于代词/名词使用错误），需改回 bikes；2) 从句结构混乱，which 指代不明确，且 provide 后名词用法错误，应为 provide clean/healthy air（通常说 clean air）；3) back 应为 bike 或 bikes；4) 表达“乘坐/使用这种交通工具”应使用 use/ take this mode of transportation/to get to school。建议：把 bags 改为 bikes，简化并分段表达原因，使用清晰的从句和恰当的名词搭配。
