Bike— Part 1 채점 보고서

제안: 回答直接，也提供了生日礼物和与朋友在公园玩耍的细节，但后半部分有明显的时态和句子结构错误，例如“when I get”应使用过去时，“we playing”缺少谓语动词。建议按时间顺序组织内容，并避免用“And what”连接句子；最后用完整表达说明这段经历令人难忘。

예시: Yes, I did. My mother gave me a bike for my eighth birthday, and I was thrilled when I got it. I immediately took it to the park to show my friends, and we spent the afternoon riding it together. It’s still one of my fondest childhood memories.

제안: 你回答了问题，并用交通费用较高解释自行车受欢迎的原因，这是相关的支持细节。不过，“in my city”重复，且“bike”应使用复数或泛指表达；“bus fees or taking a taxi is”结构也不自然。建议先概括自行车的普及程度，再用更简洁、具体的方式说明它是省钱的出行选择。

예시: Yes, bikes are quite popular in my country, especially in the city where I live. Public transport and taxis can be expensive, so many people cycle to work or run errands to save money. It’s also a convenient way to get around during rush hour.

× And what when I get this present, I was really excited and I bring it to show it to my friends and we playing with my bike in the park and it was a very memorable.

✓ And when I got this present, I was really excited. I brought it to show my friends, and we were playing with it in the park. It was a very memorable experience.

ID 5（过去时错误）：这里讲的是童年发生的事情，因此 get 和 bring 应分别使用过去式 got 和 brought。改写后的 we were playing 也与过去的叙述时间一致。

× And what when I get this present, I was really excited and I bring it to show it to my friends and we playing with my bike in the park and it was a very memorable.

✓ And when I got this present, I was really excited. I brought it to show my friends, and we were playing with it in the park. It was a very memorable experience.

ID 8（动词-ing形式错误）：playing 前缺少助动词。若保留进行时，应说 were playing；过去进行时表示当时正在公园里玩。

× And what when I get this present, I was really excited and I bring it to show it to my friends and we playing with my bike in the park and it was a very memorable.

✓ And when I got this present, I was really excited. I brought it to show my friends, and we were playing with it in the park. It was a very memorable experience.

ID 26（句子结构错误）：“it was a very memorable”中的 memorable 是形容词，后面缺少名词。可补上 experience，构成完整表达 “a very memorable experience”。

× Yes, bike is quite popular in my country, especially in my city in the city I live in.

✓ Yes, bikes are quite popular in my country, especially in the city where I live.

ID 1（单复数问题）：这里泛指自行车这一类事物，应使用复数 bikes，而不是单数 bike。复数主语也应与 are 搭配。

× In this city the travel costs for for instance the bus fees or taking a taxi is really expensive and it's unaffordable for most of the people working here.

✓ In this city, travel costs—for instance, bus fares and taxi fares—are really expensive, and they are unaffordable for most people who work here.

ID 27（主谓一致错误）：主语 travel costs 是复数，因此谓语应使用 are，而不是 is。列举例子时使用 bus fares 和 taxi fares，也让表达更清楚、结构更一致。
