自行车— Part 1 評分報告

建議: 回答基本直接，但时态错误：谈论过去应使用“when I was a child”，而不是“when I am a child”。此外，答案只有简单的否定，建议补充一个具体原因或相关细节，并使用“because”连接，使回答更完整、自然。

範例: No, I didn’t have a bike when I was a child because my parents thought it was unsafe to ride on the busy roads near our home.

建議: 回答切题且语法基本正确，但“our country”和“there are lots of bikes”表达较笼统。建议使用“my country”，并具体说明自行车流行的原因、使用场景或人群，例如通勤、锻炼和环保；可以用“because”或“especially”增强逻辑和细节。

範例: Yes, bikes are quite popular in my country, especially among students and office workers, because they are affordable and convenient for short journeys.

× No I didn't have a bike when I am a child.

✓ No, I didn't have a bike when I was a child.

“when I am a child”中的“am”是现在时，但句子谈论的是过去的童年时期，并且主句使用了过去时“didn't have”，因此应将“am”改为过去式“was”。建议在描述过去的经历或状态时，统一使用一般过去时，例如：“When I was a child, I played outside.”
