自行车— Part 1 评分报告

建议: 内容比较完整，但表达有些重复、时态和衔接可改进。注意句子简洁并使用恰当时态和连接词。例如将重复的‘to the school’合并，使用过去时描述童年经验，增加一两处具体细节（如骑车的感觉或频率）以丰富内容。

示例: Yes, I had a bike when I was a child. It was green and my mother bought it because our school was within cycling distance and she was often too busy to drive me. As a result, I cycled to school almost every day, which made me feel independent and helped me stay active.

建议: 回答直接但口头语较多、用词不够准确。应去掉口头填充词（如 ‘uh’），使用更地道的表达并补充具体例子或影响。可以说明共享单车普及的原因、使用场景或带来的好处与问题，使回答更具体连贯。

示例: Yes, bikes are very popular in my country. The government has promoted bike-sharing schemes, so people can scan a QR code to unlock a bike and ride it to work or school. This makes commuting cheaper and more convenient, although it sometimes causes cluttered streets.

× I remember the color is green.

✓ I remember the color was green.

原句使用现在时“is”与前文“had a bike”（过去时）时间不一致，回忆过去的事应使用过去时。建议将动词改为过去时“was”，以保持时态一致。

× my mother was too busy to pick me up from the school or send me to the school.

✓ my mother was too busy to pick me up from school or send me to school.

原句中不应在可数名词“school”前重复使用定冠词“the”，且短语‘pick up from school’和‘send to school’通常不加冠词。建议去掉“the”。（注意：此处主要是冠词问题，但按题目列表中最贴近的分类为“Modal verb usage”因为句中有不定式结构与情态/能力相关，实际问题为冠词使用。）

× So I need to ride the bicycle to go to school, so she bought me one.

✓ So I needed to ride the bicycle to go to school, so she bought me one.

前半句描述的是过去的情形，应使用过去时“needed”而不是现在时“need”，以与后半句“she bought me one”保持时态一致。建议把“need”改为“needed”。

× we have rolled out the policy, uh, of uh, uh, common share bicycle and everyone can scan the QR code to unlock the bicycle and drive them to the company or school.

✓ we have rolled out a policy of shared bicycles, and everyone can scan a QR code to unlock a bicycle and ride it to work or school.

原句中有多处搭配与介词问题：1) “common share bicycle” 词序和搭配不当，应为“shared bicycles”或“a policy of shared bicycles”；2) “the QR code” 可改为“a QR code”更自然；3) “drive them to the company or school” 中“drive”通常用于驾驶机动车，骑自行车应用“ride”，且代词“them”指代不清，单数“a bicycle”应使用“it”；4) “to the company” 更常用“to work”。建议按改正句修改以符合英语习惯。

× everyone can scan the QR code to unlock the bicycle and drive them to the company or school.

✓ everyone can scan a QR code to unlock a bicycle and ride it to work or school.

主语“everyone”视为单数时，其后动词形式“can scan”是正确的，但代词“them”与“a bicycle”单复数不一致，应使用单数代词“it”。此外“drive”不用于自行车，应改为“ride”。建议将“them”改为“it”，并用“ride”。
