有一词典中有这样一句，I can't imagine myself cycling to work for 20 kilometers　every day.
但又有词典　Don't imagine yourself to be always correct. imagine 后到底该用什么形式呀？可以用－ing 吗？急！急！急！谢谢！

其实你说的这2个句子，imagine 的意思不同，用法也不同。首先区分一下它的意思
如果是 想象 ----那么：imagine sb/ sb's/ + doing; imagine doing sth

I can't imagine myself cycling to work for 20 kilometers　every day. 我不能想象我每天骑车20公里去上班。

i can't imagine her sailing across the Atlantic
i can't imagine going abroad all by myself.

如果是作为 认为来说，也就是你的第二个例句
那么它的用法—————— imagine one/ oneself to be ....
to be ..作宾补 ..
Don't imagine yourself to be always correct.
不要认为你自己总是对的
