Bike— Part 1 채점 보고서

제안: 用更直接的主题句开始，避免信息不一致（“bike”与“bag”混淆），并用一到两句具体细节支持。可以简化句子结构，使用连接词使叙述更连贯。比如先说明有自行车，再具体讲颜色、学习过程和频率。

예시: Yes, I did. I had a small red bike that my parents bought me when I was seven. I learned to ride it in our country yard with my dad helping me at first, and after that I rode it almost every day to the park with my friends.

제안: 回答时先给出明确立场，然后用具体理由和例子支持。注意语法与用词（如改正“bike sharing service”为“bike-sharing services”，避免“every people”）。使用连接词（for example, moreover, therefore）使论证更有条理。

예시: Yes, I think bikes are quite popular in my country. They are inexpensive and many cities offer bike-sharing services. For example, many commuters use shared bikes for short trips to work or the store, and because cycling reduces pollution, more people prefer it as a practical option.

× Yes I did. I had a small red bag that my parents bought for me when I was 7 and I used it to ride to the park with my friends.

✓ Yes, I did. I had a small red bike that my parents bought for me when I was 7, and I used it to ride to the park with my friends.

句子中的语义错误：学生把“bike（自行车）”错误地写为“bag（包）”，根据上下文应为“bike”。此外，原句缺少逗号，建议在“Yes,”之后加逗号，在两个并列分句之间加逗号并用 and 连接，使句子更清晰。建议改为“I had a small red bike...” 来保持时态一致（过去时）并符合语义。

× I learned to ride it in our country yard because my dad helped me at first and after that I rode it almost every day.

✓ I learned to ride it in our country yard because my dad helped me at first, and after that I rode it almost every day.

主要是标点问题，两个并列分句之间应加逗号并用 and 连接使句子更自然。时态使用正确（过去时），不需要修改动词形式。建议在“at first”后加逗号前后分隔更清楚。

× Well, I think bikes are quite popular in my country because they are cheap and many cities have bike sharing service.

✓ Well, I think bikes are quite popular in my country because they are cheap and many cities have bike-sharing services.

“bike sharing service”应改为复数或连字符形式“bike-sharing services”，因为前文提到的是“many cities have ...”，表示多个城市拥有多种/多处服务，量词和名词需保持一致。同时用连字符把复合名词连成“bike-sharing”更符合习惯用法。

× For example, a lot of people use shared bikes for short trips to work or the store and it's also good for the environment so every people prefer them.

✓ For example, a lot of people use shared bikes for short trips to work or the store, and it's also good for the environment, so people prefer them.

原句有多个问题： 1) “every people” 是错误表达，应改为“people”或“every person”。“every”后应接单数名词，不能接复数“people”。 2) 句子缺少必要的逗号以分隔并列从句。 3) 语义上“so people prefer them”更自然。建议使用“people prefer them”保持主谓一致并避免错误量词用法。
