为什么I went to school为什么不写成i did go to school呢?

谢谢

1. 过去式在动词上变,把动词的一般式变成过去式即可。went 是go的过去式。
2. 过去式肯定式不用助动词 did, 否定句和疑问句中才用 did.
I went to school. (肯定式)
Did you go to school? (疑问句助动词 did 要提前,谓语动词一律用原形,不管是第几人称。)
I didn't go to school. (否定句由助动词 did +not 构成,谓语动词一律用原形,不管是第几人称。)
3. 肯定句中出现了 did 意思就变了。如
I did go to school. (由于简单句中不能有两个谓语动词,所以此处的did是助动词,表达强调。意思是 “我的确是去了学校。”)
You did a good job. (did 此处不是助动词而是动词 do 的过去式。意思是“你做的很好”)

I went to school.表示动作发生在过去某一时间,即表示过去时。
i did go to school.虽然也发生在过去时间但这里强调“的确(did)”语气比上一句更加突出。

do提前有强调的意思 i did go to school意思是我确实去了学校
