Bike— Part 1 채점 보고서

제안: 回答直接，但时态错误。因为是在谈过去，应将“am”改为“was”。此外，答案只有一个简单句，可以补充一个具体原因或相关经历，使回答更完整，例如说明家庭经济情况、居住环境，或你当时通常使用的交通方式。

예시: No, I didn’t have a bike when I was a child. My parents thought it was unsafe to ride on the busy roads near our home, so I usually walked or took the bus instead.

제안: 回答观点明确，但“the sharing bikes”表达不自然，建议改为“shared bikes”或“bike-sharing services”。同时，回答过于简短，可以使用“especially”补充流行的地点或人群，并说明人们喜欢骑车的原因，例如方便、便宜和环保。

예시: Absolutely. Shared bikes are very popular in my country, especially in large cities. Many people use them because they are convenient, affordable, and better for the environment.

× No, I didn't have a bike when I am a child.

✓ No, I didn't have a bike when I was a child.

句子描述的是童年时期的经历，属于过去的时间，因此要使用一般过去时。主语是 I，be 动词的过去式应为 was，而不是 am。建议看到 when I was a child、when I was young 等过去时间表达时，使用 was/were。

× Absolutely, many people use the sharing bikes.

✓ Absolutely, many people use shared bikes.

这里的 bikes 表示“被共享的自行车”，应使用过去分词 shared 作定语，而不是现在分词 sharing。shared bikes 意为“共享单车”。此外，泛指共享单车时通常不使用定冠词 the。
