自行车— Part 1 評分報告

建議: 句子有时态和语法错误，句子结构不够清晰，回答较冗长且重复信息。建议：1) 使用正确的时态（过去时）并把回答分成主题句和一两句支持细节。2) 避免重复（如“good for our health”和“get exercise”表达类似意思），用连词使结构更连贯。3) 提供具体细节（例如骑什么样的自行车、骑多远、和谁一起骑）。

範例: Yes, I had a bicycle when I was a child. I used it almost every day to ride to school, which was about two kilometers from my home, and I often went with my younger sister. Riding kept me fit and gave me a sense of freedom.

建議: 表达不够清楚，语法和词汇使用有误，句子逻辑混乱。建议：1) 开头直接表明观点，然后用一两条具体原因支持。2) 注意名词和代词的一致性，使用合适的词组（例如“bike-sharing services”而不是“model mobile bikes”）。3) 给出具体例子或数据使观点更有说服力。

範例: Yes, bicycles are very popular in China. In many cities bike-sharing services are widely available, offering cheap and convenient rides that many people use for short trips and commuting. This promotes a greener and healthier lifestyle.

× Yes I have and I really like biking because it's good for our health and I can get exercise.

✓ Yes, I had one and I really liked biking because it's good for our health and I could get exercise.

原句时态混用：问题问的是过去是否有自行车（When you were a child?），回答应使用过去时。但句中使用现在时“I have”和现在时态“I really like”与上下文不一致。建议将与过去背景相关的动词改为过去时（had, liked, could），而描述普遍真理（it’s good for our health）可以保留一般现在时。注意标点和连词的使用。

× Also I ride a bike to school when I was little.

✓ Also I rode a bike to school when I was little.

动词时态错误：句中有时间状语“when I was little”，应使用过去时，所以动词“ride”应改为过去式“rode”。另外在口语书写中注意在句首加逗号或连词使句子更流畅（例如“I used to ride a bike to school when I was little.”）。

× Of course, because in China we proposed A greener and healthier lifestyle and this year is their model mobile bikes on the street, which people can get on easily and it costs very cheap.

✓ Of course. In China we have promoted a greener and healthier lifestyle, and this year there are shared bikes on the streets that people can easily use; they are very cheap.

原句存在句子结构混乱、多处语法和词汇错误：1) “proposed A greener...” 用词不当，应为“have promoted”（推广）而非“proposed”；2) “this year is their model mobile bikes on the street” 结构不正确，缺主语且词序错误，应改为“this year there are shared bikes on the streets”；3) “which people can get on easily” 词组用法不自然，改为“that people can easily use”；4) “it costs very cheap” 是形容词/副词混用及代词不一致，应为“they are very cheap”或“it costs very little”。建议重构句子，保持主谓一致并使用适当时态和词汇。
