Bike— Part 1 채점 보고서

제안: 回答直接，但语法和表达不够自然。有冗余（“back when I was a child”与已说明重复），动词时态和语态稍有问题（“which comes from my parents”应为过去时或简洁定语）。建议用一到两句清晰陈述，然后给一两个具体细节，如自行车的颜色、用途或与父母的关联。可使用简单连接词（e.g. and, so）保持连贯。

예시: Yes, I did. It was a red bicycle my parents gave me for my tenth birthday, and I used it every day to ride to school and visit friends.

제안: 回答观点明确，但句子过长且有重复（“is very common”与前句重复意思），连接词使用不够自然，词序和冠词问题（“eco friendly”应为 “eco-friendly”）。建议先给出直接回答，然后用一到两句话具体说明原因并举例，使用恰当的连接词（because, for example, so）使表达更连贯。注意并列项之间加入逗号或连词以改善流畅度。

예시: Yes, bikes are very popular in my country because they are affordable and practical. For example, many people use bicycles to commute in cities, and others ride to nearby towns for short trips because it saves money and is eco-friendly.

× Yes, sure I had back when I was a child.

✓ Yes, sure — I had one when I was a child.

这个句子的问题是过去时表达不自然且缺少宾语。原句“I had back when I was a child”中“back”不能单独用作时间副词来表示“那时候”，并且缺少具体宾语（a bike）。应补上宾语并把时间短语放在合适位置，形成自然的过去时陈述。建议把“back”去掉或放在逗号后的从句位置，并补上“one”来代替“a bike”。

× It was a birthday gift which comes from my parents.

✓ It was a birthday gift that came from my parents.

这里出现时态和关系从句中动词形式不一致的问题。主句使用过去时“was”，所以定语从句中应使用过去时“came”而不是现在时“comes”。此外，用“that”或“which”都可以，但在限制性从句中更常用“that”。因此改为“came”。

× Sure, bikes are pretty popular in my country.

✓ Sure, bikes are pretty popular in my country.

该句语法正确，时态和主谓一致均无问题，因此无需修改。

× You can see the area where people use bikes to commute and also travel to nearby cities is very common and affordable and eco friendly.

✓ You can see that people using bikes to commute and travel to nearby cities is very common, affordable and eco-friendly.

原句结构混乱，包含多个并列成分但缺少连接词，致使主句与从句关系不清晰。把“that”引导的名词性从句放在主句后，并用现在分词短语“people using bikes”作为主语，可以更清楚地表达意思。同时并列形容词用逗号分隔，且“eco friendly”应写为“eco-friendly”。另外也可以改为复数主语：“It is very common, affordable and eco-friendly for people to use bikes to commute and travel to nearby cities.” 以避免主谓不一致。
