Bike— Part 1 채점 보고서

예시: Yes, I had a small blue bike when I was a child. I often rode it around my neighborhood with my friends.

제안: 回答与自行车是否受欢迎无关。请先明确表达观点，再说明原因或举例，例如提到通勤、锻炼或城市里的自行车道。

예시: Yes, I think bikes are quite popular in my country. Many people use them to commute short distances or exercise, especially in cities with dedicated bike lanes.

× I'm tired.

✓ I was tired.

问题询问的是你小时候是否有自行车，语境指向过去。若这句话是在描述当时的感受，应使用一般过去时：将“am”改为“was”。

× We are sure I'm exhausted.

✓ We were sure I was exhausted.

如果这句话描述的是过去的情况，两个现在时动词“are”和“am”都应改为过去时“were”和“was”。
