自行车— Part 1 評分報告

建議: 回答直接且自然，但有些冗余与小错误（如“within distance walking distance”重复）。建议用一句主题句回答，再用一句或两句具体且简洁的补充说明，注意避免重复表达并使用连接词使句子更流畅。例如把原因和时间点具体化。

範例: No, I didn't. Both my primary and secondary schools were close enough to walk to, so I never needed a bike. Also, my family preferred that I walk or take public transport for safety reasons.

建議: 内容具体且相关，但部分句子可更自然流畅（如“over the streets”不地道；“many people like students and office workers would use them”结构冗长）。建议用连接词组织细节，并提供更具体的例子或数据来增强说服力。注意使用更地道的短语。

範例: Yes, bikes are very popular in my country. Shared bikes are everywhere, and many students and office workers use them for short commutes because they are cheap, convenient and help avoid traffic jams. For example, I often see people riding shared bikes near subway stations during rush hour.

× Both my primary and secondary schools were within distance walking distance of my home, so I never needed a bike to get there.

✓ Both my primary and secondary schools were within walking distance of my home, so I never needed a bike to get there.

句子中出现了重复短语 “within distance walking distance”，属于多余重复。应保留常用表达 “within walking distance”。此外原句时态和结构正确，修改仅去掉冗余以符合地道英语表达。建议：记住固定搭配 “within walking distance” 表示“在步行可及的距离内”，不要重复使用相同含义的词语。

× You can see shared bikes over the streets.

✓ You can see shared bikes on the streets.

这里的错误是介词使用不当（应为“on the streets”而不是“over the streets”），根据题单中允许的类型，归类为涉及动名词形式前的介词/搭配错误，实际问题是在介词搭配。正确搭配是 “on the streets”。 建议：多记常见搭配，如 “on the street(s)” 表示“街上”，而 “over” 常用于表示“在…上方/超过”。

× Many people like students and office workers would use them for short commutes because they are very convenient and cheap, and they also avoid traffic jams.

✓ Many people, like students and office workers, use them for short commutes because they are very convenient and cheap, and they also help avoid traffic jams.

原句中逗号和从句断开不当，短语 “like students and office workers” 应作为插入语，用逗号分隔；此外动词时态和助动词使用更自然的表达是直接用一般现在时 “use”，并在“avoid traffic jams”前加主语或用动词短语使句子流畅（如 “help avoid”）。建议：插入语要用逗号隔开；描述习惯性事实用一般现在时；注意动词搭配使意思清晰（例如“help avoid” 表示“有助于避免”）。
