Bike— Part 1 Report

Suggestion: 语法和表达需要更准确与自然。注意动词时态和冠词（例如“when I was a child”，“a training wheel(s)”），避免重复词（如“every every”）。回答要更简洁，最多五句，先给主题句，然后用1-2个具体细节支持，使用连接词提高连贯性。

Example: Yes. I had a small red bike when I was a child. It had training wheels, so I learned to ride safely, and I used to cycle every afternoon with my older brother. Those rides were fun and helped me gain confidence on two wheels.

Suggestion: 流利度和词汇较好，但要减少填充词（umm, uh）并修正名词单复数与句子结构（例如“scores of shared bikes”，“scan a QR code”）。回答应更有条理，可先作总体评价，然后用1-2个具体例子支持，使用连接词如“for example”或“because”增强逻辑。

Example: Yes, bikes are very popular in my country. For example, there are many shared bikes on the streets that people can rent by scanning a QR code, so many commuters use them to get to work or school because they are cheap and convenient.

× When I was child I had a small red bike and it is what it was with a training wheels.

✓ When I was a child I had a small red bike and it was with a training wheel.

错误类型：单复数错误。说明：原句缺少冠词“The child”应为“a child”。此外“training wheels”与不匹配的动词及冠词使用混乱。建议：说“a child”表示“一个孩子”；“training wheel”若指单个应使用单数，若指一对或多个则用复数。更自然的表达是“I had a small red bike with training wheels.”；在这里可写为“When I was a child, I had a small red bike with training wheels.”（中文：当我还是个孩子时，我有一辆带辅助轮的小红自行车）。

× I often ride this bike every time, every every afternoon with my older brother.

✓ I often rode this bike every afternoon with my older brother.

错误类型：现在分词/时态混用。说明：句子中描述过去习惯，应使用过去时“rode”，而不是现在时“ride”。“every time”与“every afternoon”重复且不需要现在分词。建议：用过去时表达过去经常发生的动作：“I often rode this bike every afternoon with my older brother.”（中文：我常常每天下午和哥哥一起骑这辆自行车）。

× there are scores of shared bike on the street

✓ there are scores of shared bikes on the street

错误类型：单复数错误。说明：短语“scores of”后面应接复数名词，因此“bike”应改为“bikes”。建议：将名词改为复数以匹配数量词："scores of shared bikes"。（中文：街上有很多共享单车）。

× people can, uh, scan their QR code, uh, and to ride this bike to go to school or go to work

✓ people can scan their QR codes and ride these bikes to go to school or to work

错误类型：动词+ing/不定式误用与数一致问题。说明：并列动词前不应使用不定式“to ride”在“can”之后；另外“QR code”与“bike”应与复数主语people和bikes一致，分别改为“QR codes”“these bikes”。建议：保持并列结构一致并使名词数一致："people can scan their QR codes and ride these bikes to go to school or to work."（中文：人们可以扫码并骑这些自行车去学校或上班）。
