Bike— Part 1 채점 보고서

제안: 回答切题，但需要改正时态和冠词：谈论童年经历应使用过去式“had”，并在单数可数名词“bike”前加“a”。还可以补充一个具体细节，例如骑车的地点或用途，让回答更完整。

예시: Yes, I had a bike when I was 15. I used to ride it around my neighborhood and sometimes went to school on it.

제안: 回答表达了明确观点，也给出了原因，但“bike”和“motorcycle”前的冠词及名词形式需要调整。可以具体说明自行车为何不方便，并用一个补充细节让理由更有说服力。注意比较时可说“more convenient than riding a bike”。

예시: No, I don't think bikes are very popular in my country. Many people prefer motorcycles because they can travel longer distances more quickly, especially when they commute to work.

× Yes, I have bike when I was 15 years old.

✓ Yes, I had a bike when I was 15 years old.

句子描述的是你15岁时的经历，属于过去，因此 have 应改为过去式 had。建议根据时间标志词判断时态；这里的 when I was 15 years old 表明应使用过去时。

× Yes, I have bike when I was 15 years old.

✓ Yes, I had a bike when I was 15 years old.

bike 是可数名词单数，前面通常需要冠词。此处表示“有一辆自行车”，应在 bike 前加不定冠词 a。

× I think the motorcycle is more convenient than bike.

✓ I think the motorcycle is more convenient than a bike.

bike 是可数名词单数，在这里泛指一辆自行车，前面需要不定冠词 a。比较时可以说 more convenient than a bike。
