Bike— Part 1 채점 보고서

제안: 回答直接表达了“没有”，但语法和表达不够自然。“my household is very poor”应改为“my family was very poor”，“when I was a child”对应过去时，所以“can't afford”应改为“couldn't afford”。另外，“afford my study”不自然，可以说“afford my education”或“pay for my schooling”。建议使用“because”连接原因，并补充一个具体结果，使答案更完整。

예시: No, I didn’t. My family was quite poor when I was a child, so we couldn’t afford to buy a bike because we had to spend our money on basic needs and my education.

제안: 回答观点明确，但存在重复和语法问题。“are convenient, are affordable, affordable”重复，应删减；“bikes”是复数，后面应使用“they”，而不是“it”；“avoid traffic problems”表达不够准确，可以说“reduce traffic congestion”。建议先给出主题句，再用“because”连接两个具体理由，并加入城市或通勤场景作为细节。

예시: Yes, definitely. Bikes are very popular in my country because they are affordable and convenient, especially for short journeys. They also help people avoid traffic jams and reduce pollution in crowded cities.

× No, my household is very poor and when I was a child my family even can't afford my study.

✓ No, my household was very poor, and when I was a child, my family couldn't even afford my education.

句子描述的是“小时候”的过去情况，因此主句中的 is 应改为过去式 was。建议先根据时间标志词判断时态：看到 when I was a child 等过去时间表达时，相关动词通常要使用过去时。

× No, my household is very poor and when I was a child my family even can't afford my study.

✓ No, my household was very poor, and when I was a child, my family couldn't even afford my education.

can't 是现在时形式，而句子讲述的是小时候的情况，所以情态动词 can 应改为过去式 could，否定形式为 couldn't。注意：过去发生的“能够或不能够”通常使用 could 或 couldn't。

× Sure, bikes are convenient, are affordable, affordable for most people, and it can avoid many traffic problems.

✓ Sure, bikes are convenient and affordable for most people, and they can help avoid many traffic problems.

bikes 是复数名词，指代它时应使用复数代词 they，而不能使用单数代词 it。建议先判断被指代名词的单复数，再选择对应代词：单数用 it，复数用 they。

× Sure, bikes are convenient, are affordable, affordable for most people, and it can avoid many traffic problems.

✓ Sure, bikes are convenient and affordable for most people, and they can help avoid many traffic problems.

原句中 are affordable 重复，而且几个并列成分连接不清，导致句子结构不自然。应将 convenient 和 affordable 连接成并列形容词短语，并删除重复内容。建议使用 and 连接结构平行的成分，例如 convenient and affordable。
