Bike— Part 1 채점 보고서

제안: 回答切题，也用父亲买车并教你骑车的经历补充了细节。最后一句的“until now”表达不自然，建议改成“since then”或说明你现在是否又开始骑车；另外，“bike”和“bicycle”重复，可适当替换或删减。

예시: Yes, I had a bike as a child. My dad bought it for me and taught me how to ride it. I didn’t ride much after that, although I’ve started cycling again recently.

제안: 开头直接回答了问题，但“China”重复，且最后一句没有说完，影响表达完整度。可以说明共享单车如何方便人们，例如扫码解锁、短途出行；注意用“a QR code”表达“二维码”，并在五句以内结束回答。

예시: Yes, bikes are popular in China, especially shared bikes. You can see them on many city streets. They’re convenient for short trips because people can unlock one by scanning a QR code and leave it at their destination.

× But after that I seldom rode a bicycle until now.

✓ But after that, I haven't ridden a bicycle since then.

“since then”表示从过去某个时间一直延续到现在，通常要用现在完成时。原句用了表示过去的“rode”，与“until now”表达的时间范围不一致。可以使用“haven't ridden”，并用“since then”表达“从那以后”。

× I think that they bring convenience for people in their daily lives because they just need to scan the code on the bike and then they.

✓ I think that they bring convenience for people in their daily lives because they just need to scan the code on the bike, and then they can ride it.

句末的“and then they”后缺少谓语和完整意思，导致句子未完成。可以补上“can ride it”，使后半部分成为完整的句子。
