怎样将英语过去式句子改为一般现在时句子

Answer 1

楼主的提问太笼统了，举个例子
I went to the supermarket to buy snacks.过去时
I go to the supermarket to buy snacks. 现在时
或者 I was going to buy some snacks. 过去时
I am going to buy some snacks.现在时
将表示过去的动词改为现在时态。

Answer 2

把谓语动词或助动词从过去式改为原型，再看主语是第三人称单数还是其他情况做动词变化，就可以了
希望这一回答对你有所帮助！

追问

说的不清楚，比如说He came here yesterday.

追答

He came here yesterday.
He(不用改) comes（came原型为come，第三人称单数动词加s）here.
yesterday就不能用了因为它和过去时连用，这里也可以接every day之类的时间状语
