Bike— Part 1 채점 보고서

제안: 回答基本相关，但存在明显的语法、时态和表达问题。应使用过去时，例如“when I was eleven”和“I had a bike”；“buy bike”不符合语境，如果想表达骑车，应说“ride my bike”。建议先直接回答，再补充频率和用途，并使用“because”或“so”连接细节。

예시: Yes, I had a bike when I was eleven. I rode it to school every day because it was convenient and enjoyable. It also helped me get some exercise.

제안: 回答与问题相关，但内容不清晰，且没有明确说明自行车是否流行。应使用现在时回答当前情况，使用过去时描述三十年前的情况；“China country”“a lot of bikes are my friends”和“Used to buy back”表达不自然。建议加入清晰的对比、具体原因和连接词，例如“Although...，bikes are still popular because...”。

예시: Yes, bikes are still quite popular in China, especially in smaller cities. Thirty years ago, almost every family owned a bicycle, and people often rode to work or school. Nowadays, many people use shared bikes because they are cheap and convenient.

× when I eleven

✓ when I was eleven

“I eleven”中缺少系动词“was”。表示年龄时，应使用“主语 + was/were + 年龄”，所以应改为“when I was eleven”。

× Yes, when I eleven I have a bike.

✓ Yes, when I was eleven, I had a bike.

问题描述的是童年时期的经历，应该使用过去时。“have”要改为过去式“had”；同时，“I eleven”要改为“I was eleven”。

× I buy bike

✓ I bought a bike

可数名词“bike”是单数时，前面通常需要冠词。“bike”前应加不定冠词“a”。由于这是过去发生的事情，“buy”还应改为过去式“bought”。

× Every day I buy bike, go to school.

✓ Every day, I rode my bike to school.

这句话描述的是过去的日常活动，因此动词应使用过去时。“ride”过去式是“rode”。同时，“rode my bike to school”是更自然、准确的表达。

× a lot of bikes are my friends

✓ there were a lot of bikes in my hometown

这里想表达“我的家乡有很多自行车”，应该使用“There be”句型。“30 years ago”表示过去，所以使用“There were”，而不是“There are”。

× 30 years ago in China country, my hometown, a lot of bikes are my friends.

✓ Thirty years ago, there were a lot of bikes in my hometown in China.

“30 years ago”明确表示过去，动词应使用过去时，因此“are”要改为“were”。原句中的“are my friends”也不能准确表达“有很多自行车”，应改为“there were a lot of bikes”。

× in China country, my hometown

✓ in my hometown in China

“China country”不是自然的英语表达。“in my hometown in China”中的第一个“in”表示地点“在我的家乡”，第二个“in”表示“在中国”，介词使用更准确。

× Used to buy back, go to school.

✓ People used to buy bikes and go to school by bike.

原句缺少主语，不能直接用“Used to”开头。“used to”前面需要有主语，例如“People”。同时，两个并列动作“buy bikes”和“go to school”之间应使用连词“and”。

× Used to buy back, go to school.

✓ People used to buy bikes and go to school by bike.

原句用逗号连接两个动作，结构不完整。并列两个动作时，应使用连词“and”，所以应说“buy bikes and go to school”。
