自行车— Part 1 評分報告

建議: 回答需要更自然且结构更清晰。首先，句子有事实性错误或不连贯（“child”与“18 years old”矛盾），应直接给出主题句并用一到两句具体细节支持。避免多余或不完整的话（如“Secondly on the roads.”）。建议用简单明了的时态和连词（e.g. because, so, and）把想法连起来，并控制在最多五句内。

範例: I had a bike when I was a teenager — my mother gave it to me for my 18th birthday. I enjoyed cycling because it kept me fit and was a fun way to explore my neighborhood. For example, I used to ride to the park every weekend, which helped me relax and stay healthy.

建議: 需要更流利和更具体的支持细节。句子总体可懂但有停顿和重复（“this kind of, uh, this kind of”），应去掉犹豫词并给出具体例子或理由（例如城市共享单车、通勤、政府政策）。使用连接词如“because”、“for example”使回答更连贯。控制在一到三句内会更自然。

範例: Yes, bikes are very popular in my country because they are affordable and eco-friendly. For example, many people use shared bikes for short commutes in the city, and local governments have built bike lanes to encourage cycling.

× When I was a child, my mother bought a bicycle for me as a gift in my 18 years old birthday.

✓ When I was a child, my mother bought a bicycle for me as a gift on my 18th birthday.

问题类型：Article errors（以及部分数字序数用法）。原句中“in my 18 years old birthday”用法不正确，英文中应使用“on”来表示在某个具体的日期或“birthday”，并且年龄应使用序数词或缩写形式“18th”而不是“18 years old”修饰“birthday”。建议：把介词改为“on”，把“18 years old birthday”改为“18th birthday”或“my eighteenth birthday”。注意英语中“birthday”前常用介词“on”。

× I really like cycling because it is a good way for me to protect my health.

✓ I really like cycling because it is a good way for me to maintain my health.

问题类型：Sentence structure errors（以及词汇选择/搭配问题）。原句使用“protect my health”搭配不太自然，英语中更常用“maintain”或“keep”来表示保持健康。建议：将“protect my health”改为“maintain my health”或“keep me healthy”。

× Secondly on the roads.

✓ Secondly, it is convenient for short trips on the roads.

问题类型：Sentence structure errors。原句片段“Secondly on the roads.”不是完整句子，缺主语和谓语，导致句子不完整。建议将其扩展为完整句子，例如说明第二点并给出具体内容，如“Secondly, it is convenient for short trips on the roads.”。

× Yes, I think bike is very popular in my country.

✓ Yes, I think bikes are very popular in my country.

问题类型：Singular and plural issue。原句用单数“bike”与情景不符，应使用复数“bikes”表示一般性陈述；同时主语“bikes”应与系动词复数形式“are”搭配，而不是省略或用单数动词。建议：将“bike is”改为“bikes are”。

× Most of the people try to use this kind of, uh, this kind of green transport to protect the environment.

✓ Most people try to use this kind of green transport to protect the environment.

问题类型：Article errors（和冗余结构）。原句中“Most of the people”在一般陈述时更自然为“Most people”；另外“this kind of, uh, this kind of”重复且口语填充词应去掉。建议：简化为“Most people try to use this kind of green transport to protect the environment.”
