自行车— Part 1 評分報告

建議: 回答直接，但只有一个词，缺少具体信息。建议先明确回答，再补充一两点细节，例如几岁开始骑车、在哪里骑，或是否喜欢骑车。

範例: Yes, I had a small blue bike when I was a child. I usually rode it around my neighborhood with my friends after school.

建議: 回答没有完成，because 后面缺少原因，因此表达不完整。建议先直接回答，再说明一到两个具体原因，例如自行车价格实惠、方便通勤或有助于锻炼身体。

範例: Yes, I think bikes are quite popular in my country because they’re affordable and convenient for short trips. Many people also ride them to get some exercise.

× Mm, yes, because

✓ Mm, yes, because many people use bikes for commuting.

“Because”引导原因从句，后面需要接完整的原因内容；原句停在“because”处，句意不完整。可以补充一个完整的原因从句，例如“many people use bikes for commuting”（很多人骑自行车通勤）。
