自行车— Part 1 评分报告

建议: 首先要直接回答问题，并使用正确的过去时。因为你谈论的是童年经历，应将“haven't learned”改为“didn't learn”，并说“until I was 12”而不是“until 12 years old”。另外，“sheared bicycle”用词错误，应改为“shared bicycle”或“a bike-sharing service”。可以再补充一个具体原因，使答案更完整；注意使用“so”或“because”等连接词，且避免不自然的表达。

示例: No, I didn’t have a bike when I was a child because I didn’t learn how to ride one until I was 12. After that, I usually used shared bicycles when I needed to travel around my neighborhood.

建议: 你的回答直接并且有合理原因，但可以进一步提高自然度和具体性。“travel in short distances”应改为“travel short distances”或“travel over short distances”。建议加入一个具体场景或结果，例如人们骑自行车上下班、上学，或者用来避开交通拥堵。可以使用“especially”或“for example”连接细节，使答案更丰富。

示例: Yes, bicycles are quite popular in my country, especially in large cities. They are convenient for travelling short distances, and many people use them to commute to work or avoid traffic jams.

× No, I haven't learned how to ride a bike until 12 years old.

✓ No, I didn't learn how to ride a bike until I was 12 years old.

“until I was 12 years old”表示过去的明确时间，因此不能使用现在完成时“haven't learned”，应使用一般过去时“didn't learn”。同时，年龄前需要完整的主语和谓语“ I was”。

× So when I have to ride a bike I will use sheared bicycle.

✓ So, when I had to ride a bike, I used a shared bicycle.

这段话是在描述童年时期的经历，所以“have to”和“will use”应改为过去时“had to”和“used”。此外，单数可数名词“bicycle”前需要冠词“a”。“shared”表示“共享的”；“sheared”通常表示“剪切过的”，不符合语境。

× Yes, bicycles are quite popular in my country and it's really convenient for people to travel in short distances.

✓ Yes, bicycles are quite popular in my country, and they are really convenient for people to travel for short distances.

表示“短距离出行”时，通常使用介词“for”，而不是“in”。因此应说“travel for short distances”。另外，“bicycles”是复数，使用代词“they”比“it”更一致。
