Bike— Part 1 채점 보고서

제안: 回答需要更自然、简洁并且语法准确。开头用主题句直接回答并给出一两个具体细节即可。避免重复和句子碎片；时间、频率等信息应表达清楚。可以用连接词如“so”或“therefore”来保证衔接。注意语法：例如用“it became a 50-minute trip each way”或更自然的说法“it took me about 50 minutes each way”。

예시: Yes, I did. My mother bought me a bike when I was about eight, and I rode it to school every day. It usually took me about 50 minutes each way, so cycling became a regular part of my daily routine.

제안: 回答内容较好，但有个别用词和表达不够地道。保持一句主题句，接着用具体例子支持，并用连接词如“for example”或“as a result”。注意词汇搭配：用“cost-effective”连字符，且应使用“relying on cars”而非“residing”。可以补充一两个更具体的细节（如“commuting to work or school”或“reduce traffic congestion”）。

예시: Yes, I think bikes are very popular in China because they are cost-effective and environmentally friendly. For example, bike-sharing services in major cities let commuters and students cover short trips quickly, which helps reduce traffic congestion and car use.

× About a 50 minutes trip each day each way I became.

✓ It was about a 50-minute trip each way every day.

该句结构混乱，缺少主语和谓语的正常顺序。原句“About a 50 minutes trip each day each way I became”中“I became”与前半句不匹配且用词错误。应使用“It was”来引入时间/距离的描述，并把“50 minutes”改为复合形容词“50-minute”，放在名词“trip”前，且把“each day each way”调整为更自然的“each way every day（每天单程）”。建议：用“It was + 描述”或用主语“I”搭配适当动词（例如“I had about a 50-minute trip each way every day”）。

× because I cycled so often. About a 50 minutes trip each day each way I became.

✓ because I cycled so often. It was about a 50-minute trip each way every day.

两句衔接处缺少合适的连接或停顿，且原句将时间/路程描述放在句首而未用正确介词或结构连接。应使用“It was”来承接前句，或使用连接词“so”/“therefore”等。中文建议：注意句子之间的衔接，使用适当的连接词或代词承接前文。

× bicycles are widely used in China because they provide a cost effective and environmentally friendly way to commute.

✓ Bicycles are widely used in China because they provide a cost-effective and environmentally friendly way to commute.

“cost effective”作为复合形容词修饰“way”时应使用连字符：cost-effective。英文中复合形容词在置于名词前通常需连字符以避免歧义。中文建议：在英语写作中，当两个词共同修饰一个名词时，若放在名词前，通常用连字符连接。

× For instance, bike sharing services in major cities allow workers and students to cover short distances quickly without residing on cars.

✓ For instance, bike-sharing services in major cities allow workers and students to cover short distances quickly without relying on cars.

原句使用“residing on cars”不恰当，动词“reside”意为“居住”，与语境不符。正确用词为“rely on cars”（依赖汽车）。另外“bike sharing”作为复合名词修饰时建议用连字符“bike-sharing”。中文建议：注意动词选择，保证动词与上下文语义一致；复合名词修饰时使用连字符。
