Bike— Part 1 Báo cáo

Gợi ý: 回答切题，也提供了一个具体时间，但“drive a bike”不自然，骑自行车应说“ride a bike”。可以补充一个简短细节，例如你骑车去哪里或当时的感受，让回答更完整。

Ví dụ: Yes, I had a bike when I was in junior high school. I learned to ride it so I could cycle to school and visit my friends.

Gợi ý: 你直接表达了观点，但“China is called back country”意思不清晰，也不符合自然表达；“Before and now people used to bike”存在时态和搭配问题。建议说明自行车受欢迎的具体原因或使用场景，并用“in the past”和“nowadays”进行对比，例如人们过去骑车通勤，现在也有人骑车锻炼。

Ví dụ: Yes, bikes are still quite popular in China. In the past, many people used them to commute, and nowadays, people also ride bikes for exercise or to get around crowded cities.

× You know, China is called back country.

✓ You know, China is known as a country where bicycles are common.

这里的“back country”不能自然地表达“中国是自行车很普及的国家”，而且把“country”用作单数可数名词时通常需要冠词。可以改用“a country where bicycles are common”来清楚、自然地表达这个意思。

× Before and now people used to bike to exercise.

✓ In the past, people used to ride bikes for exercise, and they still do today.

“used to”表示过去经常发生、但现在不一定继续的习惯，因此不能同时用“now”表示现在仍然如此。改为先说明过去的习惯，再用一般现在时“they still do today”表达现在的情况。
