Bike— Part 1 채점 보고서

제안: 你的回答不够自然且有语法和用词错误。建议：1) 直接以主题句回答问题（例如：No, I didn’t）。2) 用一到两句具体且相关的原因支持答案，注意时态和词汇（例如：‘I lived near a subway station, so I didn’t need a bike.’）。3) 避免不确定或错误的词（如“Plus”、“mobile banks”、“row them”），用正确表达替换（例如：‘shared bikes’或‘bike-sharing services’）。4) 控制长度不要超过5句，使用连接词如 ‘because’ 或 ‘so’ 来保持连贯。

예시: No, I didn’t. I lived near a subway station when I was a child, so I didn’t need a bike. Also, bike-sharing services were already common in my city, so I could rent a bike when necessary.

제안: 回答总体方向正确但表达不够自然且有拼写/搭配错误。建议：1) 开门见山回答（例如：Yes, they are very popular.）。2) 用一到两句具体原因支持，例如通勤方便或环保，注意拼写（‘commute’不是 ‘write back’），并用连词使句子流畅。3) 提供一个具体例子或短比较会更好（例如：shared bikes in big cities are widely used for short trips）。

예시: Yes, they are very popular. Shared bikes are widely used in cities because they are convenient for short trips and help reduce air pollution. For example, many people use them to commute from subway stations to their workplaces.

× Sadly no. I live near the subway station so there's no need for me to own a bike Plus.

✓ Sadly no. I lived near the subway station, so there was no need for me to own a bike.

原句情景是谈论过去（“when you were a child”），却使用现在时“live”和现在存在结构“there's no need”，时态不一致。应把动词改为过去式以匹配时间背景。建议将“live”改为“lived”，“there's no need”改为“there was no need”。此外“Plus”在句尾不合适，可删除或改为连接句子时使用“Besides”并放在句首。

× The mobile banks are already popular when I was a child, so if I want to ride a bike I just row them.

✓ Mobile bike-sharing services were already popular when I was a child, so if I wanted to ride a bike I just used them.

原句时态混杂：先用现在时“are already popular”又接过去时间状语“when I was a child”，不一致。条件句“if I want”也应使用过去时“if I wanted”，表示过去习惯。动词“row”用法不当且拼写错误，应为“ride”或在此指共享单车用“use them”。另外“mobile banks”表意错误，应该是“mobile bike-sharing services”或“shared bikes”。建议统一用过去式并改正词汇。

× People write backs to work or school every day out of convenience and Environmental Protection.

✓ People ride bikes to work or school every day for convenience and environmental protection.

原句中“write backs”是拼写/词汇错误，应为“ride bikes”；“to work or school”介词短语位置正确，但“out of convenience and Environmental Protection”用法和大写不当。通常用“for convenience and environmental protection”表示目的或原因，且“environmental protection”不该大写。建议用“for”和小写。

× shared bikes enjoy a large popularity.

✓ Shared bikes are very popular.

“enjoy a large popularity”是非习惯搭配且结构笨拙。英语中更自然的表达是“are popular”或“are very popular”。建议使用“are popular”并在需要强调时加副词“very”。
