自行车— Part 1 評分報告

建議: 回答过于简短且重复。应直接陈述并补充一两句具体细节（例如什么时候得到、自行车的类型、是否经常骑或与谁一起骑），使用连接词使回答连贯。避免简单重复“yes”。

範例: Yes, I did. I got my first bike when I was six — it was a small red bicycle with training wheels. I rode it almost every day around my neighborhood with my friends, which helped me become more confident and independent.

建議: 回答清晰但有语法和细节不足。应注意冠词和单复数（say “bikes are”），并加入具体理由或例子（如共享单车、城市使用率、骑行文化或通勤用途），使用连接词如“because”或“for example”增强连贯性。

範例: Yes, bikes are extremely popular in my country because they are convenient and inexpensive. For example, many cities have bike-sharing programs and dedicated bike lanes, so a lot of people use bicycles for short commutes and errands.

× I think bike is extremely popular in my country.

✓ I think bikes are extremely popular in my country.

错误类型：名词单复数使用错误。句中泛指自行车时应使用复数形式或在单数前加不定冠词（a bike），并且主语为复数时谓语动词也应使用复数形式“are”。建议：当你谈论一类事物（例如自行车）时，使用复数（bikes）或使用不定冠词（a bike）并相应调整谓语。例："I think bikes are extremely popular in my country." 或 "I think a bike is extremely popular in my country."（但第二种含义不同，通常用复数）。
