Bike— Part 1 Relatório

Sugestão: 回答中存在时态和语法错误，表达不够自然；内容可以更具体，例如说明为什么小时候没有自行车，以及在大学学会骑车的经历细节。注意使用连接词使句子连贯，并控制在最多五句内。

Exemplo: No, I didn't have a bike when I was a child because my family lived in a small apartment and we usually walked or took the bus. However, when I went to university I decided to learn; within two days of practice I could ride confidently. Learning quickly helped me commute to classes and explore the city more easily.

Sugestão: 回答内容基本相关但表达有重复，语法和词汇使用需改进。建议补充具体细节（例如共享单车的品牌、使用流程或优缺点），并用连词减少重复。保持简洁且自然。

Exemplo: Yes, bikes are very popular in my country, especially shared bicycles in cities. You can often see dozens parked on the street; users simply scan a QR code with a smartphone to unlock a bike, which is usually very affordable. This system has made short trips and commuting much more convenient for many people.

× I don't have a bike when I was young, but uh, after entering university I learned how to ride bikes in just two days.

✓ I didn't have a bike when I was young, but after entering university I learned how to ride a bike in just two days.

问题类型：现在时错误（6）。句中主句描述过去的情况，应使用一般过去时“didn't have”而不是现在时“don't have”。此外“ride bikes”在此语境下更自然的单数表达为“ride a bike”。建议：叙述过去的经历时，全句采用过去时态；“a bike”或复数取决于要表达的含义，这里指学会骑自行车，用单数更常见。

× So in street, you can see many shared bikes.

✓ So on the street, you can see many shared bikes.

问题类型：介词使用错误（11）。英语中表示“在街上”应使用介词短语“on the street”而不是“in street”。建议：记住常用固定搭配，例如“on the street”“in the city”“at the corner”。

× So you just need to scan the code on it then you can ride the bike in a low price.

✓ So you just need to scan the code on it, then you can ride the bike at a low price.

问题类型：冠词/介词使用错误（22 与 11 相关，归为22）。原句中“in a low price”是错误的固定搭配，正确表达应该用“at a low price”或更自然地“for a low price”/“for a low fee”。另外在两个分句之间应加逗号以分隔。建议：记住价格相关的常用介词搭配，如“at a low price”“for a low price”“for free”。
