Bike— Part 1 Report

Suggestion: 回答总体清晰，叙述连贯有个人经历，但可以更自然并增加细节与逻辑连接词以丰富内容。例如说明骑车的感受、学骑过程或为什么车子坏了，从而展示更丰富的词汇和句型。注意避免冗余句子（如“we couldn't use it anymore”可更具体）。

Example: Yes, I did. My father bought me a bicycle for my eighth birthday, and I learned to ride it in our cul-de-sac within a week. I used to cycle almost every afternoon with my friends, which made me feel independent and confident. Sadly, the chain came off and the frame bent after only a few months, so we had to stop using it until he could fix it.

Suggestion: 回答直接且观点明确，但可以用连接词和具体例子扩展论证，例如比较不同城市、说明共享单车的影响或给出频率和原因，加强内容的具体性和词汇多样性。

Example: Definitely. Bicycles are very popular, especially in big cities such as Beijing and Shanghai, where many people use them to get to subway stations or for short commutes. In recent years, the rise of bike-sharing schemes has made cycling even more convenient, reducing traffic congestion and saving time for commuters.

× Yes I did. My father bought me a bicycle for my birthday and I rode it almost every day around the neighborhood with my friends. Unfortunately it was broken after a few months so we couldn't use it anymore.

✓ Yes, I did. My father bought me a bicycle for my birthday, and I rode it almost every day around the neighborhood with my friends. Unfortunately, it broke after a few months, so we couldn't use it anymore.

句子中原用法“it was broken”用被动结构表示“它被弄坏了”，但这里更自然的是用主动过去式“it broke”表示自行车损坏这一事件发生。错误类型属于“Past tense issue（过去时问题）”。建议：在描述事件（某物损坏）时优先使用主动过去式，例如“it broke”或“If someone broke it, use 'was broken by someone' 并指明施动者”。另外添加必要的标点（逗号）使句子更清晰。

× Definitely yes. Especially in some big cities like Beijing, there are lots of bicycles people can ride to the subway.

✓ Definitely, yes. Especially in some big cities like Beijing, there are lots of bicycles that people can ride to the subway.

原句中缺少连接词“that”或“which”来引导定语从句，使主句“there are lots of bicycles people can ride to the subway”显得不完整或口语化。此错误归类为“Incorrect use of prepositions（介词使用不当）”也可视为从句连接问题，但按给定列表应选与介词/结构相关类型。建议：在正式或书面表达中在可数名词后加上限定从句连词“that/which”来连接修饰成分，或重写为“people can use to ride to the subway”。
