Bike— Part 1 채점 보고서

제안: 回答基本切题，但有明显的词汇、时态和句子结构错误。应将“back”改为“bike”，谈论童年经历时使用一般过去时“had”；“a back”应改为“a bike”。“was thought by my father”表达不自然，应改为“was bought by my father”或“my father bought me”。此外，“birthday birthday”重复。建议先直接回答，再补充自行车的颜色、用途或使用经历，使答案更具体、自然。

예시: Yes, I had a bike when I was a child. My father bought it for me as a birthday present, and I used to ride it around my neighborhood after school.

제안: 回答切题，并提供了共享单车和便利性两个理由，但语法和表达不够自然。“it”应改为复数主语“they”或直接使用“bikes”；“in our street many shared bikes are there”应改为“there are many shared bikes on the streets”。“because you know”是多余的口语填充，可删除；“if you go to other places”可以改为“when people need to travel short distances”。建议使用“Also”或“For example”连接细节，并说明共享单车在城市中的具体用途。

예시: Yes, bikes are quite popular in my country, especially in large cities. There are many shared bikes on the streets, so people can easily use them for short trips and avoid traffic jams.

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

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

“When I was a child”表示一个已经结束的过去时间，所以应使用一般过去时“had”，而不能使用现在完成时“have had”。另外，“back”应为“bike”；“birthday birthday”属于重复表达，正确说法是“birthday gift”。

× I remember that a back was thought by my father as my birthday birthday gift.

✓ I remember that a bike was bought by my father as my birthday gift.

这里想表达“自行车被父亲买来作为生日礼物”，应使用“be + 过去分词”的被动结构：“was bought”。“thought”是“思考”的过去式或过去分词，不能表达“购买”。

× Yes, I think it is very popular in my country because you know that in our street many shared bikes are there and it's very convenient if you go to other places.

✓ Yes, I think they are very popular in my country because there are many shared bikes on our street, and they are very convenient when you go to other places.

“bikes”是复数名词，所以代词不能用单数“it”，应使用复数“they”。相应的系动词也应使用“are”，即“they are very popular”。

× because you know that in our street many shared bikes are there

✓ because, as you know, there are many shared bikes on our street

表示“某地有某物”时，应使用“There be”结构，正确语序是“There are + 复数名词”，而不是“地点 + 名词 + are there”。“many shared bikes”是复数，所以使用“there are”。
