Bike— Part 1 채점 보고서

제안: 回答总体清晰且信息完整，但可以更自然、更简洁地表达主题句并使用连接词让叙述更连贯。此外可以补充一两句具体细节（如骑行感受或丢车后的反应）以丰富内容，从而提高得分。注意不要过于冗长，控制在最多5句内。

예시: Yes, I did. My father bought me a bike in grade five because my school was quite far and my parents were busy. I rode it to school every day and really enjoyed the freedom it gave me. Unfortunately, it was stolen about a year later, which made me feel upset and more cautious about leaving things unattended.

제안: 回答直接且观点明确，但可提高连贯性与词汇多样性。用更自然的连接词替换口语化表达（如“Like”），并给出具体例子或对比（例如使用数据、不同人群的选择原因）以增强说服力。控制句子数，避免重复。

예시: Yes, bikes are very popular, particularly in large cities. Even though public transport is well developed, many people prefer cycling for short trips because it is faster and cheaper. For example, shared-bike services are everywhere in my city, and commuters often use them to travel between subway stations and workplaces.

× My father bought me a bike when I was in grade 5 because the school is quite far from my home and my parents didn't have time to bring me to school anymore.

✓ My father bought me a bike when I was in grade 5 because the school was quite far from my home and my parents didn't have time to bring me to school anymore.

句子中描述的是过去发生的情况（父亲买车、当时学校距离远、父母没有时间送我），因此时间状语从句和主句的动词也应使用过去时。原句中“is quite far”使用了一般现在时，与上下文的过去时态不一致。建议将与过去背景有关的动词都用过去式，保持时态一致。

× So I took this bike to school every day, but it was stolen by someone one year later.

✓ So I took this bike to school every day, but it was stolen by someone a year later.

短语“one year later”在英语中更常用和自然的表达是“a year later”。虽然“one year later”并非绝对错误，但在这种叙述性句子里使用冠词形式更地道。此问题归在单复数/数词表达类别，建议用更常见的短语。

× Although the transportation system is very complete right now, people would still choose bike to travel.

✓ Although the transportation system is very complete right now, people still choose bikes to travel.

原句中有两处问题：1) “would still choose”在表示现在习惯性选择时应使用一般现在时“still choose”，而非“would”。2) “choose bike”缺少冠词或复数形式，应为“choose bikes”或“choose a bike”。这里说的是人们普遍的选择习惯，用复数“bikes”更合适。建议把动词改为一般现在时，并把名词改为复数。

× Like there are a lot of shared bike in my city and it's convenient for short distance travel.

✓ For example, there are a lot of shared bikes in my city and they're convenient for short-distance travel.

句中“a lot of shared bike”存在单复数错误，正确应为“a lot of shared bikes”。另外，句首用“Like”口语化且不正式，改为“For example”更合适；“it's convenient”中的代词指代复数名词，应使用“they're convenient”；“short distance”作复合形容词修饰名词时应连字符“short-distance”。建议使用复数形式并使代词与名词一致，同时调整措辞更书面化。
