Walking— Part 1 채점 보고서

제안: 回答要更自然、语法更准确，并控制在最多五句话。避免重复，使用连词使句子更流畅。例如说明次数、时长并解释原因时，用正确时态和介词。可以把两句合并并修正语法错误。

예시: Yes, I walk a lot because I have two dogs that need daily exercise. I usually spend about two hours walking them each day, splitting the time between morning and evening. It helps both the dogs and me stay healthy.

제안: 保持时态一致并用更自然的表达，避免重复。第一句直接回答后，用一至两句具体说明原因或情况，使用连接词使逻辑更清楚。

예시: No, I didn't. As a child I spent most of my time studying at my desk, so I rarely went out for walks. Therefore, I didn't have many opportunities for outdoor exercise.

제안: 回答可以更精炼并使用恰当的连接词。提供具体细节（如安静、绿化、设施）来支撑观点，避免笼统词汇如 'the air is good'。

예시: People enjoy walking in parks because they offer a peaceful, green environment and cleaner air than busy streets. Moreover, parks often have designated paths and benches, making them safer and more comfortable for walking.

제안: 避免填充词（如 'uh'）并校正语法（例如 'can not only give'）。可以用一两句具体说明原因或描绘景色来丰富回答。

예시: I'd like to take a long walk in the mountains because the scenery is beautiful and the trails are challenging. Not only would it be a peaceful experience, but it would also provide excellent cardiovascular exercise.

제안: 修正语法和重复错误（如双写 'the'），使用过去时保持一致，避免简单短句堆砌。可以具体描述路线或活动以增加细节。

예시: This morning I walked near my home to exercise my dogs. We strolled along the local streets and through the community square, where we did some light exercises and enjoyed the fresh air.

× Yes I do, I currently have two dogs and I walk every day for their regular exercise. I spend 2 hours a day to walk them. Split between morning and evening I find walk.

✓ Yes, I do. I currently have two dogs and I walk them every day for their regular exercise. I spend two hours a day walking them, split between morning and evening.

问题类型：现在时/动词形式与动词+ing（ID 6 与 8 的结合）。原句中“I spend 2 hours a day to walk them.” 使用了不恰当的不定式“to walk”。在表示花费时间做某事时，应使用“spend ... doing ...”结构，改为“spend two hours a day walking them”。另外“Split between morning and evening I find walk.” 句子结构混乱且无谓语，需重写为“split between morning and evening”并与前句连成一句。建议：使用“spend … doing …”结构，并保证句子有完整谓语，时间短语放在合适位置。

× Did you often go outside to have a walk when you were a child? Student: No, I didn't. When I was a child, I used to spend time sitting before my desk doing my homework. I don't really spend much time outdoors to go for a walk or exercise.

✓ Did you often go outside to have a walk when you were a child? Student: No, I didn't. When I was a child, I used to spend time sitting at my desk doing my homework. I didn't really spend much time outdoors walking or exercising.

问题类型：过去时（ID 5）。原句“I don't really spend much time outdoors to go for a walk or exercise.” 时态与上下文不一致，谈论过去应使用过去时。并且“不定式 to go”用法不当，应改为动名词“walking or exercising”。此外“sitting before my desk” 更自然表达为“sitting at my desk”。建议：叙述过去的习惯或情况时统一使用过去时态，动词+ing 表示活动。

× First, the atmosphere in the park may be better than streets because there are a lot of people walking and running in parks and besides, the air is good.

✓ First, the atmosphere in the park may be better than on the streets because there are a lot of people walking and running in parks, and besides, the air is good.

问题类型：介词使用错误（ID 11）。比较“better than streets”时，需要在“streets”前使用介词“on”或使用定冠词“the streets”。同时句子中逗号和连词需更清晰以连接并列部分。建议：在表示“在街道上”时用“on the streets”，并注意并列连词的使用。

× I would go to the mountains. I think climbing a mountain can not only, uh, gives a good opportunity to take a long walk, but it can also help me to exercise better.

✓ I would go to the mountains. I think climbing a mountain can not only give a good opportunity to take a long walk, but it can also help me exercise better.

问题类型：第三人称单数错误/动词形式（ID 2 和 8）。在结构“can not only ... but ...”中，助动词后动词应为原形，不能使用第三人称单数形式“gives”。同时“help me to exercise better” 可更自然地为“help me exercise better”。建议：在情态动词或助动词后使用动词原形，并保持并列结构的动词形式一致。

× Just this morning I went for a walk near the place I live to walk my dogs. We went to the streets and the the square around where I live. We did some exercise and we inhale the fresh air.

✓ Just this morning I went for a walk near the place where I live to walk my dogs. We went to the streets and the square around where I live. We did some exercise and we inhaled the fresh air.

问题类型：冠词/时态错误（ID 22 与 5）。原句有重复词“the the square”，应删去一个“the”。“inhale the fresh air” 描述过去发生的动作，需用过去时“inhaled”。另外“near the place I live” 更自然为“near the place where I live”。建议：注意不要重复冠词，描述过去事件时使用过去时动词，并用完整的定语从句提高清晰度。
