Bike— Part 1 채점 보고서

제안: 句子有语法错误且回答不是直接陈述。首先应直接用第一人称回答，使用正确时态和冠词；其次可补充一两句具体细节（如什么时候、有哪种自行车、是否常骑）以丰富答案，但不要超过五句。添加连接词使表达更连贯。

예시: Yes. I had a red bicycle when I was about eight. I rode it to my friend’s house almost every day, so I became quite confident riding on busy streets.

제안: 回答过于简短且缺乏细节。应先给出直接观点，然后用一到两句具体原因或例子支持，例如谈及城市骑行文化、交通或环保因素，使用连接词使逻辑清晰。控制在五句内。

예시: Yes, I think bikes are very popular, especially in big cities. Many people use them for short commutes because they’re cheap and convenient, and public bike-sharing programs have also increased their use.

× Did you have bike when you are child?

✓ Did you have a bike when you were a child?

问题类型：There be issue（存在/数与冠词结合问题）。错误分析：原句缺少不定冠词“a”，以及时态与主句不一致。提问使用过去时“Did you have…”，所以时间状语“when you are child”应改为过去时“when you were a child”。此外，“bike”为可数名词，单数需用冠词“a”。改进建议：1) 可数单数名词前通常需要冠词（a/an/the），此处用不定冠词“a”。2) 问句为过去时，时间状语也要用过去时形式（are → were）。练习句型：Did you have a bike when you were a child? 可以多读几遍并替换不同名词练习（Did you have a dog when you were a child?）。
