原本打算英语

I had planned to go out with my classmates.

intend to do sth. 打算做某事mean to do sth. 本来打算干某事

What did you plan to handle this at first?

How had ever you planned on handling the business?

At first I intended to go out with my classmates.因为此处的“原来”实际上指的是“一开始”计划是这样的。所以，用at first就可以了。跟同学出去玩，直接用go out with my classmates就可以表示出来了。不用单独再加上to play with my classmates.

was/were doing sth.

intended to do something

had intended to，用虚拟语气，也就是过去完成时表示本打算而实际上没有做的事。

planning to do +STH这就可以表达你的意思了

可以用副词 originally 表示本来本来打算做 originally intend to do sth

I had plan .....
