自行车— Part 1 評分報告

建議: 注意过去时间要使用一般过去时：把“have”改为“had”。“when I was the children”不符合语法，应说“when I was a child”。回答直接，但可以补充一两句具体细节，例如自行车的颜色、用途或骑车的经历。

範例: Yes, I had a bike when I was a child. It was red, and I often rode it around my neighborhood with my friends.

建議: 回答直接，但内容过于简短，没有解释“为什么”或提供具体例子。可以补充骑自行车的人群、常见用途，或自行车在城市里的普及情况，并用“because”或“for example”连接细节。

範例: Yes, I think bikes are quite popular in my country, especially among students and people who live near their workplaces. For example, many people use them for short trips because they are convenient and inexpensive.

× Yes, I have a bike when I was the children.

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

句子描述的是过去（“when I was...”），因此主句动词也应使用过去时。将“have”改为“had”，使时态与过去的语境一致。

× Yes, I have a bike when I was the children.

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

“I was”后面描述的是说话者当时的身份，应使用单数“child”，而不是复数“children”。可以记住：“a child”表示一个孩子，“children”表示多个孩子。

× Yes, I have a bike when I was the children.

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

“child”是可数名词单数，前面需要使用不定冠词“a”。这里不是特指某些孩子，因此不应使用“the”。
