Bike— Part 1 採点レポート

提案: 语法时态和表达不准确，信息不完整。请使用正确的过去时并提供一到两句具体细节（比如谁买的、骑 bike 的频率或记忆）。在回答中先给出主题句，然后用连接词补充细节，整个回答不超过五句。

例: Yes, I had a bike when I was a child. My parents bought it for me for my tenth birthday, and I used to ride it to school and around the neighborhood almost every day.

提案: 句子结构混乱且时态和比较表达错误。请明确时间点（过去/现在），用连接词比较变化并给出具体原因或例子。保持回答简洁且逻辑清晰。

例: Bikes were very popular when I was a child, but they are less common now because more people prefer cars and public transport. However, cycling is becoming more popular again in some cities due to better bike lanes and environmental awareness.

× Yes, when I'm 15 I have a bike.

✓ Yes, when I was 15 I had a bike.

此句涉及时态错误（现在时用在描述过去的情况）。说“when I was 15”指的是过去，应使用过去时“was”和“had”。建议：当描述过去的经历或年龄时，主句和从句都用过去时，例如“when I was 10 I had…”。

× Now it's not so popular when I'm a child the bike is popular and now more popular than now.

✓ Now bikes are not so popular. When I was a child, bikes were popular, and they were more popular then than they are now.

该句包含多个时态和句子结构错误。第一部分“Now it's not so popular”最好用复数主语“bikes are”来匹配复数名词；第二部分描述过去应使用过去时“when I was a child”；第三部分比较过去与现在，应使用过去时“were more popular then than they are now”。建议：将句子拆成几句，注意主谓一致和时态一致，比较时用“then”与“now”对应过去时与现在时。
