Bike— Part 1 Báo cáo

Gợi ý: 回答简洁但可以更自然和具体。建议开头直接回应并用一到两句补充细节（如何时、谁送的、学会骑车的经历或为何是四轮车），并用连接词使语句更流畅。注意避免过多停顿词（如”uh”）。

Ví dụ: Yes, I did. I had a pink bike with training wheels when I was about six; my parents bought it for my birthday, and I used it every day to ride around the neighborhood.

Gợi ý: 回答不够直接和具体，含有填充词并且逻辑不够连贯。建议先直接给出观点，再用一到两句具体理由或例子支持（例如城市交通、共享单车、通勤习惯等），使用连接词（because, for example, moreover）提升连贯性。

Ví dụ: Yes, I think they are quite popular in China, especially in big cities like Shanghai, because many people use bikes or shared bicycles for short commutes and to avoid traffic jams.

× Yes, I had a bike when I was a child and it was a pink bike with four wheels.

✓ Yes, I had a bike when I was a child, and it was a pink bike with training wheels.

问题类型（复数/单数问题）: 原句中说“a pink bike with four wheels”在字面上是正确的，但常见的儿童自行车是两轮带辅助轮（training wheels）或三轮车，如果说“四个轮子”会让人误解为小车或滑板车。更自然的表达是“with training wheels”（带辅助轮）或改为“两 wheels”。建议在此情境中使用更自然的描述，例如“training wheels”或“two wheels”。（简体中文）

× I know. I think it's a common tool, uh, in my country, I'm in Shanghai.

✓ I know. I think they're common in my country — I'm in Shanghai.

问题类型（现在时态/主谓一致）: 原句中使用单数“it”指代“bikes”不合适，应使用复数代词“they”或复数动词形式。且“a common tool” 用法不自然，bikes更常说是“common”或“popular”。建议将句子改为“they're common”或“bikes are common”，并用破折号或分句自然连接“I'm in Shanghai”。（简体中文）
