Bike— Part 1 채점 보고서

제안: 句子结构和时态需要更准确，避免重复和语法错误。回答应直接陈述并补充一两条具体细节（例如何时、什么样的自行车、与你的关系或记忆）。尽量控制在不超过五句，使用连词使表达更连贯。

예시: Yes. I got my first bike when I was in primary school. It was a small red bicycle that my mother bought for me as a birthday present, and I spent every afternoon riding it around the neighborhood until I learned to ride without training wheels.

제안: 回答要更准确地表达观点并给出具体原因或例子。纠正词汇错误（如“shared bag”应为“shared bikes”或“bike-sharing”），并使用连接词说明原因或影响。保持回答简洁且信息具体。

예시: Yes, I think bikes are very popular in my country because many people use bike-sharing services. For example, you can often see rows of shared bikes parked near subway stations, and they are convenient and cheap for short trips.

× Yes, actually when I at primary school I had my first bike which is which was my mom bought.

✓ Yes, actually when I was at primary school I had my first bike, which my mom bought.

问题类型：句子结构错误（ID 26）。原句中缺少系动词“was”，导致时间状语从句不完整；此外“which is which was my mom bought”是冗余且语序混乱，应简化为定语从句“which my mom bought”。建议：在表示过去状态时在主语后加上正确的系动词（was），并使用正确的定语从句结构（which + 主语 + 动词）来修饰名词。

× Yeah, I think so. In our country we can see a huge number of bikes on the street, which called the shared bag.

✓ Yeah, I think so. In our country we can see a huge number of bikes on the street, which are called shared bikes.

问题类型：句子结构/词汇使用错误（归入句子结构错误 ID 26）。原句中缺少系动词“are”来引出非限制性定语从句，且“shared bag”用词错误，正确表达应为“shared bikes”（共享单车）。建议：使用正确的被动或连系结构（which are called ...），并使用恰当词汇“shared bikes”来表达“共享单车”。
