Bike— Part 1 채점 보고서

제안: 回答过于简短，缺少主题句扩展和具体细节。应给出一到两句补充说明，比如什么时候有的、谁送的或经常骑到哪里，这样更自然且信息量更大。注意使用连接词如“because”或“so”来使回答连贯。

예시: Yes, I did. I got my first bike when I was seven because my parents wanted me to get more exercise. I used to ride it around the neighborhood every afternoon with my friends.

제안: 回答总体较好，给出观点并提供了原因，但可以增加具体细节或对比来更有说服力。建议用连词（for example, because, however）拓展说明频率、场合或与其他交通方式的对比，并尽量用丰富词汇替代重复的“bikes/ride”。

예시: Yes, bikes are very popular in my country because they are cheap and convenient. For example, many people cycle to work or school in the mornings, especially in big cities where traffic is heavy, so cycling is often faster than driving.

× Yes.

✓ Yes.

该回答为简单回答“是”。句子结构完整且符合上下文，无需修改。

× Of course, bikes are popular in my country.

✓ Of course, bicycles are popular in my country.

原句语法正确。“bikes”作为复数名词与谓语“are”一致，时态与语境匹配。不过可以将“bikes”替换为更正式的“bicycles”以提升表达的正式性（这不是语法错误，仅为风格建议）。

× Many people ride bikes to go to work.

✓ Many people ride bicycles to go to work.

原句语法正确，主语与动词一致，时态恰当，意义清晰。可选地将“ride bikes”改为更正式的“ride bicycles”。
