Bike— Part 1 채점 보고서

제안: 回答直接，但过去的经历要使用过去时，将“have”改为“had”。可以补充一个具体细节，例如骑车的地点或用途，让回答更自然、完整。

예시: Yes, I had a white bike when I was a child. I often rode it around my neighborhood after school.

제안: 回答切题，也提供了例子，但“transportation”在这里用法不自然，可以说“a popular way to get around”。删去重复的“choose to”，并将“in my college”改为更自然的“on my college campus”。

예시: Yes, bikes are a popular way to get around in my country. For example, on my college campus, many students ride them to class because it’s convenient and saves time.

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

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

句子描述的是小时候的情况，且“when I was a child”明确表示过去，因此主句中的 have 也应使用过去式 had。回答过去发生或存在的情况时，注意保持时态一致。

× Yes, riding a bike is a very popular transportation in my country.

✓ Yes, riding a bike is a very popular means of transportation in my country.

transportation 通常是不可数名词，不能直接用 a 修饰。可以改为 a very popular means of transportation，其中 means 是可数名词，表示“一种交通方式”。
