Bike— Part 1 채점 보고서

제안: 回答包含了相关信息，但重复和停顿较多，影响流畅度；另外，谈论童年时应使用过去时，且“child”和“bike”前需要正确使用冠词。建议先直接回答，再简要补充现在的情况。

예시: Yes, I had a bike when I was a child, and I still have one now.

제안: 回答切题，也给出了骑车健身的原因，但开头的填充语较多。“bikes”是复数，后面应使用“they're”；“There are many people buy”结构不正确，可改为“many people ride bikes”。建议将“morning and night”换成更自然的“in the mornings and evenings”，并用连接词清晰说明原因。

예시: Yes, bikes are quite popular in China. Many people, both young and old, ride them in the mornings and evenings because cycling is a convenient way to stay fit.

× Yes, of course, not only when I when when I'm child.

✓ Yes, of course. I had one when I was a child.

问题发生在过去（小时候），所以应使用过去时。这里应将“I'm”改为“was”。此外，“a child”前需要冠词，但此处主要标注过去时错误。

× I also have bike now.

✓ I also have a bike now.

“bike”是可数名词单数，前面通常需要冠词。这里应在“bike”前加不定冠词“a”。

× I think it's popular in China.

✓ I think they are popular in China.

这里回答的是复数名词“bikes”，所以应使用复数代词“they”，并搭配“are”，而不是用单数“it”和“is”。

× There are many young people and old people, uh, buy bikes in the morning and night to keep fit and improve their bodies.

✓ Many young and old people buy bikes in the morning and at night to keep fit and improve their bodies.

原句把“There are many people”和“people buy bikes”两种结构混在一起，导致“people”后面的“buy”没有恰当的句子连接。可以直接以“Many young and old people”作主语，再接谓语“buy”。

× ...buy bikes in the morning and night...

✓ ...buy bikes in the morning and at night...

表示“在晚上”时，通常说“at night”；而“in the morning”表示“在早上”。并列时应写成“in the morning and at night”。
