Bike— Part 1 채점 보고서

제안: 回答切题，但询问的是童年经历，应使用一般过去时。将“have”改为“had”，将“I'm”改为“I was”；同时删除不必要的逗号。可以补充一个具体细节，例如谁送的自行车或你通常骑车做什么。

예시: Yes, I had a bike when I was a child. It was a small red one that my parents bought for me, and I often rode it around the neighborhood.

제안: 回答表达了肯定态度，也提到自行车有用，但“we can see it are real in the street”语法和表达不清。建议直接说明自行车很常见，例如使用“bikes are common on the streets”；后面用“they”指代复数的自行车，并具体说明它们受欢迎的原因或用途。

예시: Yes, bikes are quite popular in my country, and you can see them on the streets every day. Many people use them for short trips because they are convenient and inexpensive. I ride my bike almost every day, too.

× Yes, I have a bike, when I'm a child.

✓ Yes, I had a bike when I was a child.

问题问的是小时候的情况，因此要用一般过去时。have 应改为 had，am 应改为 was。

× Yes, we can see it are real in the street, and I use it every day. It is useful.

✓ Yes, we can see bikes on the street, and I use one every day. They are useful.

这里谈论的是复数的 bikes，因此代词应使用 them 或 they，而不是 it；同时，they 要与 are 搭配，不能使用 it are。表达“我每天使用一辆”时，可以用 one 指代单数的一辆自行车。
