问题: When was the first time you used a computer or tablet?

The first time I used a computer was in primary school. We had a computer class where the teacher taught us how to type and use some simple programs. It was really exciting because computers were new for us at that time.

I first used a computer when I was in primary school. We had a special computer class where we learned basic typing skills and how to use simple programs like Paint. It was really exciting because, back then, computers were still quite new to most of us.

1. 一般过去时：答案使用了一般过去时（“I first used”，“We had”，“we learned”）来描述过去的经历，这对于谈论第一次事件是适当的。 2. 描述性从句的使用：“where we learned basic typing skills and how to use simple programs like Paint”这句话使用了一个定语从句来增加有关计算机课的细节，使答案更丰富、更具信息量。

1. 一般过去时：答案使用了一般过去时（“used”，“bought”，“taught”，“picked up”）来描述过去的事件，这对于谈论第一次经历是合适的。 2. 事件顺序的使用：答案按照逻辑顺序排列事件（父母买了电脑 → 用它玩游戏/看动画片 → 兄弟姐妹教基础 → 学得很快），显示出清晰的组织和连贯性。
