自行车— Part 1 評分報告

建議: 用词和逻辑上有小错误，需要修正并更自然、简洁地回答。注意把“bag”改为“bike”，把年龄表达改为更自然的说法（比如“At the age of seven”或“I was seven”），并用连接词把细节串起来，控制在最多五句内。同时避免信息重复（如“while I was a child”与“after that”可精简）。可以加入一两句具体细节（比如学会后最喜欢的路线或骑行的感觉）以丰富内容。

範例: Yes, I had a bike as a child. I learned to ride it when I was seven, with my grandmother taking me to the park to practice. She stayed by my side until I could balance and pedal on my own, and after that I rode almost every day, usually along the river path near my home.

建議: 回答总体清晰且内容具体，但可更自然并使用连接词来增强连贯性。可以补充一两个具体例子或比较（例如与其他交通方式相比的优缺点），并注意词语搭配（例如‘cheaper and more convenient’而非‘cheaper and convenient’）。保持句子数量在五句以内。

範例: Yes, bikes are very popular in China. In many cities you can find hundreds of shared yellow bikes, which people unlock by scanning a QR code with WeChat. Many commuters prefer them because they are cheaper and more convenient than taking a taxi for short trips, although they can be crowded during rush hour.

× Yes, I had a bag while I was a child.

✓ Yes, I had a bike when I was a child.

原句原本为回答“Did you have a bike when you were a child?”但学生写成“bag”(袋子)而非“bike”(自行车)，这是词汇错误而非时态错误。虽然不在给定问题类型列表内，但为了与上下文一致，应改为“bike”。如果坚持按时态检查，句子时态（过去）是正确的。建议注意阅读问题关键词以避免用错词。

× I learned to ride it while I was 7.

✓ I learned to ride it when I was seven.

此句使用过去时态“learned”是正确的，但时间状语从句中应使用介词 when 而非 while 来表达年龄点（当……时）。另外数字七用单词 seven 更为书面和自然。建议把“while I was 7”改为“when I was seven”。

× There are many yellow shared bikes on the streets that you can unlock by scanning a QR code with WeChat, and lots of people use them to commute to work because they are cheaper and convenient.

✓ There are many yellow shared bikes on the streets that you can unlock by scanning a QR code with WeChat, and lots of people use them to commute to work because they are cheaper and more convenient.

句子总体为现在时，描述事实正确。但在比较级结构中，形容词连用时需使用比较级形式“more convenient”而不是形容词原形“convenient”，因为在与“cheaper”并列比较时两者需保持同一比较结构。建议将“cheaper and convenient”改为“cheaper and more convenient”。
