Bike— Part 1 Informe

Sugerencia: 回答内容直接但有重复，句子较啰嗦且缺少具体细节。建议在开头给出明确主题句，然后用一到两句补充原因或例子。避免重复表达（例如两次说明“主要因为”/“我不知道”）。可用连词（because, so, therefore）使逻辑更清晰，并将句子控制在不超过五句。

Ejemplo: No, I didn’t have a bike when I was a child because nobody taught me how to ride. As a result, my parents preferred to walk or use public transport rather than buy a bike for me.

Sugerencia: 回答有观点但重复使用“So”且句子碎片多，信息不够具体。建议先用一句明确的主题句表明观点，然后用一到两句具体说明原因或举例，如共享单车的普及时间、使用场景或对日常出行的影响。使用更多准确词汇（e.g., shared bikes, public transport, convenient）并用连词（for example, now, previously）连接句子。控制总句数不超过五句。

Ejemplo: Yes, bicycles are very popular now because of the widespread shared-bike schemes in many cities. For example, people often use them for short trips to the supermarket or to reach subway stations, which is more convenient than waiting for a bus.

× I don't think so. It's mainly because I didn't know how to ride a bike when I was a kid, mainly because no one taught me, so I don't know.

✓ I don't think so. It's mainly because I didn't know how to ride a bike when I was a kid — no one taught me, so I couldn't.

问题类型：现在/过去时混用（归入“Present tense issue”）。原句中同时出现现在时的“I don't think so”与过去时的“I didn't know”和现在时的“so I don't know”，导致时态不一致。因为说的是过去（小时候不会骑车），最后一句应使用过去时态来保持一致。建议：叙述过去经历时，全句使用过去时，例如用“couldn't”或“didn't”而不是现在时的“don't”。

× Of course. So we have a lot of shared bicycles on the road. So before we didn't have those shared bicycles. So the only transportation for us to use would be, you know, buses, subways or even walking. So right now we have shared bikes.

✓ Of course. We have a lot of shared bicycles on the road now. Before, we didn't have those shared bicycles. The only transport options then were buses, subways, or walking. Now we have shared bikes.

问题类型：时态与句子结构问题（归入“Present tense issue”）。原段落中有重复使用“So”开头、时态和表达冗余造成不流畅。第三句中用“would be”不恰当，因为是在叙述过去的事实，应该用过去式“were”。建议：去掉多余的连词，保持时态一致（现在事实用现在时，过去事实用过去时）；用简洁表达如“The only transport options then were...”。
