Bike— Part 1 採点レポート

提案: 回答基本直接，但时态错误：谈论童年经历应使用过去时“did”或“had”，不能用现在完成时“have”。此外，答案只有三个词，缺少具体信息。建议先明确回答“有/没有”，再补充自行车的用途、使用地点或频率，使答案达到2—3句并更自然。

例: Yes, I did. I had a small blue bike when I was about eight, and I often rode it around my neighborhood after school.

提案: 回答表达了明确观点，但有几处语法和用词问题：“bikes”是复数，应使用“they are very popular”；“people don't have own a bag”表达不清，可能想说“人们不一定要拥有自己的自行车”；“use a shared bike”前应加复数或冠词。建议使用“because”或“especially”连接原因，并加入具体例子，例如共享单车在城市通勤中的使用。

例: Yes, bikes are very popular in China, especially in large cities. Many people use shared bikes for short journeys because they are convenient and usually cheaper than taking a taxi.

× Yes, I have.

✓ Yes, I did.

问题是时态不一致。问句使用一般过去时“Did you have...”，回答也应使用过去时助动词“did”，不能使用现在完成时形式“have”。建议：回答一般过去时的一般疑问句时，使用“did/didn’t”。

× Yeah, it's very popular in China and these days people don't have own a bag but use a shared bike.

✓ Yeah, they’re very popular in China, and these days people don’t have their own bikes but use shared bikes.

“Bikes”是复数名词，因此不能用单数代词“it”，应使用复数代词“they”。另外，“own”前面需要物主限定词“their”，所以应说“their own bikes”，表示“他们自己的自行车”。建议：代词要与所指名词在单复数上保持一致；表达“某人自己的……”时，使用“my/your/his/her/our/their own + 名词”。

× Yeah, it's very popular in China and these days people don't have own a bag but use a shared bike.

✓ Yeah, they’re very popular in China, and these days people don’t have their own bikes but use shared bikes.

这里讨论的是自行车这一类事物，而不是一辆特定的自行车，因此应使用复数“bikes”和“shared bikes”。同时，前后名词应保持数量一致。建议：谈论一类事物时通常使用复数名词，例如“Bikes are popular”和“people use shared bikes”。
