什么情况下用be动词的过去式？

英语小辈：

一般过去时：用动词过去式

如go,work,study...

I went to school .

I worked in the daytime.

She studied English carefully.

这些动词都是行为动词（或叫实意动词），具有实际意义的动词。这类动词直接用过去式构成一般过去时。

如果动词是联系动词be时，表“是”，那就用be的过去式was,were.

我们（是)快乐的。-We were happy.

我是男生。-I was a boy.

I went to the park是一般过去啊

换成一般现在是就是I go to the park
