Bike— Part 1 채점 보고서

제안: 回答总体意思明确，但存在时态不一致和部分表达不自然的问题。建议： 1) 注意时态一致，例如描述过去经历时主要使用过去时； 2) 用一到两句补充具体细节（如骑车去学校的距离、和朋友去哪儿玩），并用连接词使结构更连贯； 3) 避免重复词汇（例如重复使用“bike”或“ride”），可用同义词替换以丰富词汇。

예시: Yes, I did. When I was ten my father bought me a small red bicycle, and I loved riding it. I usually rode it two miles to school every day, and at weekends I would cycle to the park with my friends to play football.

제안: 回答包含观点但有逻辑和用词问题。建议： 1) 第一句“I'm not worried”与问题无关，应直接给出立场（Yes/No/It depends）； 2) 用更自然的连接词（e.g. however, recently）来对比过去和现在； 3) 提供更具体的信息或例子（如城市与农村的差异、环保或交通因素）以丰富内容。

예시: I think bikes used to be very popular, especially in rural areas, because they were affordable. However, recently many people prefer electric scooters and motorbikes because they are faster for commuting in the city, though bikes are still common for short trips and exercise.

× When I was ten years old my father bought me a bike and I really enjoyed riding the bike because I use it to go to school and more importantly I can hang out with my friends.

✓ When I was ten years old my father bought me a bike and I really enjoyed riding it because I used it to go to school and, more importantly, I could hang out with my friends.

问题类型：6（现在时问题）和5（过去时问题）以及27（主谓一致/时态一致）。原句中大部分是在回忆过去（“When I was ten... bought... enjoyed”），但接着使用了现在时态的动词“use”和“can”，造成时态不一致。改为过去时“used”和“could”可保持整个句子在过去叙述中的一致性。建议：回忆过去的事情时，整句话中的主要动作应使用过去时；如果表达习惯或普遍真理可用现在时，但需明确语境区别。

× I'm not worried. In the past it used to be very popular because the price is relatively cheap.

✓ It used to be very popular in the past because the price was relatively low.

问题类型：6（现在时问题）与13（形容词/副词使用不当）以及22（冠词/词汇搭配）。原句首句“I'm not worried.”与前后语境无关，可能是口误，应删除。短语“the price is relatively cheap”在回忆过去时应为过去时且‘cheap’通常修饰人或物，描述价格更自然用“low”。故改为“the price was relatively low”。建议：回忆过去时使用过去时态；描述价格时用“low”更地道。

× But recently I think people usually ride electrical motors because it's much faster than bikes.

✓ But recently I think people usually ride electric mopeds (or electric scooters) because they're much faster than bicycles.

问题类型：13（形容词/副词使用不当）和6（现在时问题）以及27（主谓一致）。“electrical motors”用法不自然，常用词为“electric mopeds/scooters”或“electric motorcycles”等；“it's much faster than bikes”中的“it's”指代不清且需和复数主语一致，应使用“they're”或重述为“electric vehicles are much faster than bicycles”。同时“bikes”更正式为“bicycles”。建议：用正确的名词短语（electric scooter/moped/motorcycle）并保证代词与先行词数一致；保持时态为现在进行的一般陈述时使用现在时。
