Bike— Part 1 채점 보고서

제안: 回答切题，但时态和表达有误。谈论童年经历时要用过去时：用“had”代替“have”，并把“at my five years old”改为“when I was five”。可以补充一个具体细节，例如谁买的、骑车去了哪里，避免只回答“Yes”。

예시: Yes, I had a bike when I was five. It was a small red one that my parents bought for me, and I loved riding it around our neighborhood.

제안: 回答表达了观点，但“Because...”不能单独作为完整句子，而且“every home has a bicycle”过于绝对。可以把原因和观点连成完整句，并用更准确的说法描述骑自行车的普遍程度，再补充一个具体原因或用途。

예시: Yes, I think bikes are quite popular in my country. Many people use them for short trips because they are affordable and convenient, especially in busy cities.

× Yes, I have a bike at my five years old.

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

问题背景是童年时期，应用过去时。这里的“have”应改为“had”；描述五岁时也应使用“was”。建议根据问题中的过去时间（“when you were a child”）统一使用过去时。

× Yes, I have a bike at my five years old.

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

表示“在我五岁时”应说“when I was five years old”，不能说“at my five years old”。建议记住表达年龄时使用“when I was + 年龄”或“at the age of + 年龄”。

× Yes. Because every home has a bicycle.

✓ Yes, because every home has a bicycle.

“Because every home has a bicycle”是由“because”引导的原因从句，单独使用时缺少主句，构成句子片段。可以将它与“Yes”连在一起；也可以说“Bikes are popular because every home has a bicycle.”
