Bike— Part 1 Report

Suggestion: 答题要更简洁并注意时态与语法。开头用一句主题句直接回答，然后用一两句具体细节支持。避免重复短语（例如“I started then I started”），并修正语法（例如使用“practiced”而非“practice”）。可以补充一两个相关细节（如在哪里学会、谁帮你）并用连接词使句子流畅。

Example: Yes. My dad bought me a bike for my sixth birthday. I practiced riding it in the park every weekend, and my older brother helped me until I felt confident.

Suggestion: 回答要更有条理并使用更准确的词汇。先给出直接意见，然后用一到两句具体原因支持。避免口头填充词（如“uh”）和词汇错误（“sharing bags”应为“sharing bikes”或“bike-sharing services”；“scan the cord”应为“scan a QR code”）。使用连接词如“because”或“for example”。

Example: Yes, bikes are very popular, mainly because bike-sharing services are widespread. For example, people can scan a QR code to unlock a bike and return it anywhere, which makes short trips very convenient.

× I started then I started practice how to ride a bike.

✓ I started then I started practicing how to ride a bike.

句中动词“practice”在“start”之后应使用动名词（-ing 形式）表示开始做某事，因此应改为“practicing”。同时原句重复“I started”显得冗余，可保留一次或用逗号连接；建议改为“I started practicing how to ride a bike.”或“I started, then I started practicing how to ride a bike.”但更自然的是合并为“I started practicing how to ride a bike.”

× Of course there are many, uh, sharing bags along the street and then people can scan the cord to uh, to start a bike and then they can, uh, return the bikes back anywhere, which is so convenient.

✓ Of course there are many bike-sharing stations along the street and people can scan the code to unlock a bike and then return the bikes anywhere, which is very convenient.

原句中“sharing bags”是错误搭配，应为“bike-sharing stations”或“shared bikes”。“scan the cord”中的“cord”应为“code”。动词“return the bikes back”中“back”多余，因“return”已有归还含义，可去掉。最后“so convenient”可改为更正式的“very convenient”。以上修改属于词汇和介词/短语使用不当，应注意固定搭配和词形。
