自行车— Part 1 評分報告

建議: 回答要更自然并且语法准确。使用主题句直接回应，然后用一两句支持细节。避免重复信息，注意时态和冠词，并用连接词使表达连贯。例如将“I think it dangerous”改为“I thought it was dangerous”。

範例: No, I didn’t have a bike as a child because I never learned to ride. As a result, my parents felt it would be unsafe for me, so they didn’t buy one. Later, I learned to ride a scooter instead.

建議: 回答总体清晰但需更流畅并使用多样词汇与连接词。避免简单重复“bikes are”。可以给出具体例子或比较数据来增强说服力，并注意复数和冠词使用（"cars and buses"）。

範例: Yes, definitely. Bicycles are among the most popular means of transport here because they’re cheap and very convenient for short trips. For example, many people cycle to work or school to avoid traffic and save money compared with cars and buses.

× No, when I was a child I didn't have a bike because I didn't know how to ride a bike and I think it dangerous. So my parents didn't give me a bike when I was a child.

✓ No, when I was a child I didn't have a bike because I didn't know how to ride a bike and I thought it was dangerous. So my parents didn't give me a bike when I was a child.

问题类型 ID 对应：6（现在时问题）。解释：句中主句用的是过去时（"when I was a child", "didn't know"），但后半句“I think it dangerous”混用了现在时和缺少动词/补语结构，且表达应为过去时且需完整结构“thought it was dangerous”。改为过去时一致性（thought）并补全系动词“was”。建议：保持时态一致，句中描述过去经历时把相关动词都用过去式，注意系动词的使用（it is/was + 形容词）。

× Yes, of course bikes are. Bikes are one of the most popular transportation in our country because they are convenient and cheaper than other transportation like car and buses.

✓ Yes, of course bikes are. Bikes are one of the most popular forms of transportation in our country because they are convenient and cheaper than other transport such as cars and buses.

问题类型 ID 对应：17（定冠词使用不当）/ 22（冠词错误）。解释：原句中"one of the most popular transportation"不自然，因为"transportation"为不可数名词，需用形式短语如"forms of transportation"或使用可数名词"modes of transport"；比较对象也应使用复数（cars and buses），并在列举前用合适的连接词如"such as"。此外"cheaper than other transportation like car and buses"中"car"应为复数且前后搭配不一致。建议：将不可数名词改为可表达可数类别的短语（forms of transportation）或用复数名词，并把比较对象保持复数一致，使用"such as"引出例子。
