Bike— Part 1 채점 보고서

제안: 你的回答没有直接回答“小时候是否有自行车”，而且把 bike 说成了 bag，导致意思不清。应先明确回答“Yes, I did”或“No, I didn’t”，然后补充自行车的来源、用途或使用经历。注意过去经历要使用一般过去时，例如“had”“bought”和“used”。

예시: Yes, I did. My mother bought me a bike when I was about seven years old. I often rode it around my neighborhood after school.

제안: 你基本表达了自行车环保且常用的观点，但“Yet”不适合放在句首表达肯定观点；“green”应改为“environmentally friendly”，“convenience”应改为形容词“convenient”。此外，“use bikes to where they want to go”结构错误，应说“use bikes to get to places”或“ride bikes wherever they want to go”。建议先直接回答，再用原因和具体场景展开。

예시: Yes, bikes are quite popular in my country, especially in large cities. They are environmentally friendly and convenient for short journeys. Many people ride them to work, school, or nearby shops to avoid traffic jams.

× Yes, I have a bag. Uh, what is brought from my mom?

✓ Yes, I had a bike. Uh, it was bought by my mom.

问题发生在谈论童年经历时使用了现在时“have”。因为问题使用“when you were a child”描述过去，所以应使用过去时“had”。同时，“is brought”是现在时被动结构，不符合过去时间，应改为“was bought”。

× Yes, I have a bag. Uh, what is brought from my mom?

✓ Yes, I had a bike. Uh, it was bought by my mom.

被动语态的基本结构是“be动词 + 过去分词”。这里应使用过去时“was”加过去分词“bought”，表示“它是我妈妈买的”。表示动作执行者时，应使用介词“by”，而不是“from”。

× Yet it is a green and convenience.

✓ Yes, bikes are green and convenient.

“convenience”是名词，不能与“green”并列作表语。这里需要使用形容词“convenient”，表示“方便的”。另外，主语是复数“bikes”，所以应使用“are”。

× Yet it is a green and convenience.

✓ Yes, bikes are green and convenient.

“a”只能放在单数可数名词前面，不能放在形容词并列结构“green and convenient”前面。这里是在泛指自行车这一类事物，因此使用复数名词“bikes”，不需要冠词“a”。

× People often use bikes to where they want to go.

✓ People often use bikes to go where they want to go.

“use bikes to”后面需要接动词原形，表示使用自行车去做某事。因此应在“to”后面加上动词“go”，构成“use bikes to go”。“where they want to go”表示“他们想去的地方”。
