Bike— Part 1 Báo cáo

Gợi ý: 主要问题有语法错误、表达不自然、信息不清楚且冗余。回答应直接回应问题并给出清晰原因，句子不超过5句，使用连接词并提供具体细节。建议先用一句主题句明确回答（Yes/No），再用1–2句解释原因并给出具体例子或结果。注意时态和主谓一致（e.g. "When I was a child, I couldn't..."），避免不必要的短语如“because I'm not”。

Ví dụ: No, I didn't have a bike when I was a child. My parents thought it was unsafe, so they never bought one for me. Besides, I couldn't keep my balance well, so I felt nervous riding. As a result, I learned to enjoy walking and playing other sports instead.

Gợi ý: 表达有信息但语法和用词错误，句子结构不够清晰。应直接回答并用具体细节支持，使用连接词（e.g. "because", "for example"）。纠正搭配和短语（例如："public bikes", "scan a QR code" 或 "use an app"），避免模糊表达“throw the phone”。尽量将信息分为2–3句，保持自然流畅。

Ví dụ: Yes, bikes are quite popular in my city because there are many public bike-sharing stations. People can unlock bikes easily using a smartphone app or by scanning a QR code. For example, I often use a shared bike to travel short distances, which is faster and cheaper than taking a taxi.

× Not uh, because my parenting is unsafe and because when I was a children I can't keep my balance on the back so we cancel it. And because I'm not.

✓ No, because my parents were strict/unsafe and when I was a child I couldn't keep my balance on the back, so we cancelled it. Also, I wasn't allowed to.

问题类型：主谓一致、复数/单数、时态和助动词使用。错误说明与改进建议（简体中文）： 1) “my parenting is unsafe” 用词不当，意思应为“我的父母/家长”，应使用复数“parents”；同时原句时态应为过去，改为“were”。 2) “when I was a children” children 是复数，应使用单数 child。主语和名词数不一致。 3) “I can't keep my balance” 叙述过去的经历应使用过去时，改为“couldn't”。 4) “so we cancel it” 也应使用过去时，改为“cancelled”或“didn't do it”。 5) 最后句“And because I'm not.” 不完整且时态不符，可改为“I wasn't allowed to.” 或补全原因。 改进建议：注意名词单复数（child/children, parent/parents），保持时态一致（叙述过去经历用过去时），助动词随时态变化（can't -> couldn't）。将不完整句子补全以表达完整意思。

× Yes, we have many public bike in my city and we just throw the phone to by the time of the bike and I think the bike is convenient for us so it's popular.

✓ Yes, we have many public bikes in my city and we just use our phones to pay for the bike, and I think bikes are convenient for us so they are popular.

问题类型：量词/可数名词及代词使用、不定冠词与主谓一致（简体中文）： 1) “many public bike” 中 bike 为可数名词，应使用复数 bikes 或在前面加不定冠词 a public bike（在此语境用复数）。 2) “throw the phone to by the time of the bike” 语句混乱，意图应为用手机支付/解锁共享单车，正确表达可为“use our phones to pay for/unlock the bike”。 3) “the bike is convenient for us so it's popular” 中泛指自行车应使用复数“bikes are... they are”或改为“This bike is... it is”。 改进建议：注意可数名词的单复数形式，使用恰当的动词短语表达动作（use phones to pay/unlock），以及代词和动词在单复数上的一致。
