Bike— Part 1 채점 보고서

제안: 回答要用正确的时态和更自然的表达，句子要简洁并包含必要细节。注意语法（如过去时）和词汇搭配（例如："blue bike"、"training wheels"），避免冗长或重复。可以用一到两句说明外观和为什么记得它。

예시: Yes, I did. It was a small blue bike with training wheels because my father wanted it to be stable for me. I remember riding it in the park near our house and feeling very proud when I learned to pedal by myself.

제안: 回答要更自然、语法正确并提供具体原因或例子。使用更恰当的短语（例如："popular"、"lower cost than cars"、"good for the environment"），并用连接词（e.g. "because", "for example"）把理由组织好。控制在最多五句话。

예시: Yes, bikes are very popular in my country because they are affordable and convenient. For example, many people use them to commute short distances to work or school. They are also better for the environment than cars, since they produce no emissions and reduce traffic congestion.

× Yes, I absolutely have a bike when I was a child.

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

句子中描述过去的情况（when I was a child），因此谓语动词必须使用过去时。原句使用现在时态“have”与时间状语不一致。建议把动词改为过去式“had”。

× It's a blue colored bike which hand the two extra wheels because my father said it is very stable for children.

✓ It was a blue bike with two extra wheels because my father said it was very stable for children.

原句存在多个问题：1) “blue colored”不自然，通常说“a blue bike”即可；2) 使用定语从句“which hand the two extra wheels”结构错误，动词“hand”不合适，且应使用介词短语“with two extra wheels”来表示“有两个辅助轮”；3) 句子叙述仍为过去，应把动词改为过去时（was，said前后时态一致）。建议将句子改为“It was a blue bike with two extra wheels because my father said it was very stable for children.”

× Yes, in fact almost everybody has a bike in our country.

✓ Yes, in fact almost everybody has a bike in our country.

该句语法正确。主语“almost everybody”视为单数，谓语动词“has”符合主谓一致。无需修改。

× In my opinion, I think ride a bike has a lower cost than car and it's good for environment.

✓ In my opinion, I think riding a bike costs less than a car and it's good for the environment.

原句问题包括：1) 动名词/不定式使用错误——“I think ride a bike”应使用动名词短语“riding a bike”或不定式“to ride a bike”，但在此结构中更自然用“riding a bike”；2) 动词短缺与比较结构不当——“has a lower cost than car”不自然，应改为“costs less than a car”；3) 缺少冠词和介词短语——“good for environment”需加定冠词“the environment”。建议改为“In my opinion, I think riding a bike costs less than a car and it's good for the environment.”
