自行车— Part 1 評分報告

建議: 回答已经表达了主要意思，但存在一些语法与表达不自然的问题。改进建议： 1) 使用更自然的过去时表达，例如 “My parents decided not to buy me one” （去掉不必要的 to）。 2) 简化句子结构，避免冗长，并用连接词使逻辑更顺畅，例如先给主题句再补充原因。最多不超过5个句子。 3) 提供一两个具体细节（例如大概年龄或害怕的原因），让回答更具体且有说服力。 示例改进句型可练习并仿用。

範例: No, I didn't. I learned to ride a bike when I was about eight, but I was too scared of falling over. So my parents decided not to buy me one, and I mostly walked or took the bus to school.

建議: 回答能表达基本观点，但存在语法错误、用词不当和不够具体的问题。改进建议： 1) 修正明显错误（例如 “ride a bag” 和 “choose back” 是错误表达），应改为 “ride a bike” 和 “choose biking/ride bikes”。 2) 使用连接词（for example, also）使句子更连贯，并提供更具体的群体和原因（例如学生通勤、上班族短途出行、健身爱好者）。 3) 控制句子数量与长度，确保不超出5句并保留主题句后加两三条支持细节。

範例: Yes, bikes are quite popular. For example, many students ride bikes to school because it's cheap and convenient. Others use cycling as a form of exercise or for short commutes in the city.

× No I didn't.

✓ No, I didn't.

句子本身时态正确，但缺少逗号来分隔感叹或否定的短语，增加逗号使句子更自然、符合书写规范。建议：在口语转写或书面表达中在“No”后加逗号。

× I learned how to ride a bike when I was a child, but I was afraid of having an accident so my parents decided to not buy me one.

✓ I learned how to ride a bike when I was a child, but I was afraid of having an accident, so my parents decided not to buy me one.

问题类型归为“动词过去分词形式”是因为短语“decided to not buy”中不必要地在不定式“to”后插入否定副词“not”，更自然和常见的形式是“decided not to buy”。另外句中缺少逗号来分隔两个分句。建议：把“decided to not buy”改为“decided not to buy”，并在连接词“so”前加逗号。

× Yes, many people like riding bikes. In my country, for some students they will ride a bag to go to school and for other people they may choose back as a way of exercising.

✓ Yes, many people like riding bikes. In my country, some students ride bikes to go to school, and other people may choose biking as a way of exercising.

原句存在句子结构和词汇使用错误： 1) “for some students they will ride a bag” 中“ride a bag”是错误搭配，应该是“ride bikes”。此外不需要同时使用“for some students”和主语“they”，造成冗余。建议把结构简化为“some students ride bikes to go to school”。 2) “for other people they may choose back” 中“choose back”没有意义，应为“choose biking”或“cycle”。 3) 连接两个并列分句时在and前使用逗号更清晰。建议：改为“some students ride bikes to go to school, and other people may choose biking as a way of exercising.”
