自行车— Part 1 评分报告

建议: 回答直接，但句子后半部分有明显语法问题：“which is my mom bought”结构不正确；“for my birthday gift”也不自然。可以用“which my mom bought for my birthday”说明是谁买的以及购买的时间。

示例: Yes, I had a bike when I was in junior high school. My mom bought it for me as a birthday present, and I rode it to school quite often.

建议: 回答有明确观点和原因，也使用了“For example”来补充细节。不过例子只是一个未完成的名词短语，没有说明学生和上班族如何使用自行车。请补充完整句子，并具体说明骑车的场景或好处。

示例: Yes, bikes are quite popular in my country because they’re affordable and can be faster than cars in busy cities. For example, many students and office workers ride them for short trips because they’re easy to park and help them avoid traffic.

× Yes, I used to have a bike when I was in junior high school, which is my mom bought for my birthday gift.

✓ Yes, I used to have a bike when I was in junior high school, which my mom bought for me as a birthday gift.

“which is my mom bought”结构错误。此处用 which 引导定语从句，which 已经充当 bought 的宾语，因此不需要再加 is。表达“作为生日礼物买给我”时，用“bought for me as a birthday gift”。

× For example, many students and office workers.

✓ For example, many students and office workers ride bikes.

原句只有主语“many students and office workers”，没有谓语动词，因此是句子片段。补上“ride bikes”作为谓语，句子才完整。
