自行车— Part 1 評分報告

建議: 回答缺乏逻辑性和准确性。首先话题句应直接回答“是”或“不是”，然后用一到两句具体说明原因或细节。避免自相矛盾（例如先说有自行车却又说不会骑），并使用连接词使句子连贯。可以提供更多具体细节比如年龄、谁给的自行车或后来是否学会骑。

範例: Yes, I had a bike when I was a child. My parents bought it for me when I was seven, but I couldn't ride it at first because I was afraid of falling. Later, my older cousin taught me how to balance and by the time I was nine I could ride confidently.

建議: 回答简短但基本明确。建议使用更准确的主谓一致（say “they are popular”），并加入具体细节或原因来支撑观点，例如在城市通勤、环保或运动方面的用途。使用连接词（because, for example, especially）使回答更连贯。

範例: Yes, I think bikes are quite popular in my country because many people use them for short commutes and exercise. For example, in big cities you can see dedicated bike lanes and lots of commuters cycling to work during rush hour.

× I did have a bike when I was a child because I don't know how to ride it. I didn't know how to ride it.

✓ I had a bike when I was a child, but I didn't know how to ride it.

问题类型：过去时错误。原句中“did have”虽然语法上可用作强调，但在此处使用不自然；并且句中紧接着出现“because I don't know how to ride it”时态混用，前半句谈过去应使用过去时，后半句也应保持过去时，故把“don't”改为“didn't”。建议：当描述过去的状态或动作时，统一使用一般过去时（如 had，didn't），避免不必要的助动词强调或与现在时混用。

× Uh, I think it is popular because I always see people ride bikes on the street.

✓ Uh, I think they are popular because I always see people riding bikes on the street.

问题类型：现在时错误/主谓一致与动词形式使用不当。句中“it is popular”用单数代词指代复数名词“bikes”不正确，应使用复数代词“they”并与复数动词“are”一致；此外“see people ride bikes”虽可接受，但更自然的表达是“see people riding bikes”表示正在进行的动作或习惯性看到的情形。建议：指代复数名词时使用复数代词和动词（they are）；在表示看到某人正在做某事时可用“see someone doing something”。
