Bike— Part 1 채점 보고서

제안: 回答开头直接回应了问题，但后续表达有多处不完整或难以理解，例如“my dad wants me to lend back”和结尾“I think it's”。请明确说明父亲如何帮助你，并用过去时描述学习骑车的经历。减少“uh”等填充词，避免句子说到一半中断；补充一个具体细节即可。

예시: Yes, I did. My dad bought me a bike when I was a child and helped me learn to ride it. I fell off a few times at first, but after practising in the park, I finally got the hang of it.

제안: 你给出了环保、价格实惠和方便等相关理由，内容方向不错。不过，“riding bike”应改为“riding a bike”或“cycling”；谈论普遍特点时要保持现在时，例如用“doesn’t produce”，不要突然切换到过去时“didn’t release”。“cheap and affordable”意思重复，且最后一句“You can get every”没有说完。建议选取两三个理由，用连接词串联，并提供一个具体例子。

예시: Yes, bikes are quite popular in my country. They are an environmentally friendly and affordable way to get around, especially for short trips. For example, many people cycle to nearby shops or use shared bikes to travel to work.

× Yeah, sure, I had a bike when I was a child, uh, because my dad wants me to uh, lend back and I maybe I failed the first time, but after, uh, such a lot of uh, attention, I finally learned how to ride a bike and I think it's.

✓ Yeah, sure, I had a bike when I was a child, uh, because my dad wanted me to learn how to ride a bike, and maybe I failed the first time, but after a lot of practice, I finally learned how to ride a bike.

这段话讲的是童年时发生的事情，因此描述当时父亲的想法应使用过去时 wanted，而不是现在时 wants。结合后文“学会骑自行车”的语境，lend back 应为 learn how to ride a bike。讲述练习过程时，用 a lot of practice 比 a lot of attention 更合适。

× Definitely yes, because riding bike is uh, green and it, it didn't release any uh, harmful gas and it's uh, and for most people, it's cheap and affordable and it is very convenient.

✓ Definitely, yes, because riding a bike is green, and it doesn't release any harmful gas. For most people, it's cheap and affordable, and it's very convenient.

bike 是可数名词单数，前面通常需要冠词，因此应说 riding a bike，而不能说 riding bike。

× Definitely yes, because riding bike is uh, green and it, it didn't release any uh, harmful gas and it's uh, and for most people, it's cheap and affordable and it is very convenient.

✓ Definitely, yes, because riding a bike is green, and it doesn't release any harmful gas. For most people, it's cheap and affordable, and it's very convenient.

这里是在说明骑自行车的一般特点，而不是描述过去某次发生的事情，所以应使用一般现在时 doesn't release，而不是一般过去时 didn't release。
