Bike— Part 1 채점 보고서

제안: 回答直接且语法正确，但表达过于简短，缺乏细节和连接词。建议在开头用一句主题句回答，再补充1–2个具体细节（例如谁买的、骑什么地方、何时学会、感受），并使用连接词使答案更连贯。控制在不超过5句。

예시: Yes, I did — I had a red bicycle that my parents bought me when I was seven. I learned to ride it in the park near our home, and I used to go there with my friends every weekend. Because of that bike, I became more confident and active outdoors.

제안: 回答明确但信息较泛，使用了简单原因。建议补充具体例子或比较（如城市与农村的使用差异、通勤或健身用途），并使用连接词扩展理由，使观点更有说服力。保持句子数在1–4句内。

예시: Yes, I think bicycles are very popular, especially in big cities where traffic is heavy. Many people use them for short commutes or shopping because bikes are cheaper and often faster than cars during rush hour. In contrast, people in rural areas use bikes more for casual rides and errands.

× I had a bike when I was a child.

✓ I had a bike when I was a child.

该句语法正确，时态和主谓一致均无问题，无需更改。

× Yes, I think bikes are popular in my country because it's convenient.

✓ Yes, I think bikes are popular in my country because they are convenient.

问题类型：3（There be issue）。 解释（简体中文）：原句中“it's convenient”用的是单数代词“it”，但指代的是前面的复数名词“bikes”，因此代词与先行词在数上不一致，应该使用复数代词“they are”。建议：在指代复数事物时，用复数代词（they/them）并注意动词形式（they are）。
