Bike— Part 1 채점 보고서

제안: 句子需要更清晰和连贯。注意不要含糊（如“bag”应为“bike”），避免重复填充词（umm）过多。可以先用一句话直接回答，再用一两句具体细节补充（例如年龄、谁送的、是否还保留）。使用连接词使叙述更流畅。

예시: Yes. My father bought me a bike when I was seven, and I still have it. I used to ride it to the park near our home every weekend, which helped me learn balance quickly.

제안: 表达观点清楚，但句子有语法和词汇小错误，且末尾单词不完整。可以用更自然的连接词（e.g. because, so）并给出具体例子或比较（如在小城市或农村的情况）。避免重复词（very, the very）。

예시: Not really. In large Chinese cities many people prefer the subway because of heavy traffic and limited bike parking, although bikes are still common in smaller towns and rural areas for short trips.

× all of us had a bag when I when we are little.

✓ all of us had a bike when we were little.

原句中含义混乱且单复数不当。“all of us had a bag” 与上下文不符合（问题询问自行车），应为“bike”。此外时态应为过去时，主句用“were”对应复数主语“we”。建议：确认所指名词（bike vs bag），并将“are little”改为过去式“were little”。

× my father gave me a bike as a gift when I was 7 years old and I have kept for now.

✓ my father gave me a bike as a gift when I was 7 years old and I have kept it until now.

句子中“gave”和“was”使用了过去时，但后半句错误使用现在完成时且遗漏宾语代词“it”。应使用现在完成时“have kept”加上宾语“it”并用“until now”或“ever since”表示持续到现在。建议：补上宾语代词，并使用完整时间短语，例如“have kept it until now”。

× so many people prefer taking the subway rather than by.

✓ so many people prefer taking the subway rather than biking/using bicycles.

原句末尾用“by”不完整，“by”需要后接交通工具名词（如 "by bike"）。此外在口语中说“rather than bike”不够自然，推荐用动名词或名词短语，如“biking”或“using bicycles”。建议：改为“rather than biking”或“rather than using bicycles”。

× I don't think bikes are very popular in China 'cause there are too many people and the very frequent traffic jam in big cities,

✓ I don't think bikes are very popular in China because there are too many people and very frequent traffic jams in big cities,

原句中“the very frequent traffic jam”有冠词和单复数错误，应去掉不必要的定冠词“the”，并将“traffic jam”改为复数“traffic jams”。此外口语缩写"'cause"写为正式场合可用"because"。建议：去掉多余冠词并保持名词正确单复数形式。
