I found this: (https://goo.gl/CBMnZo)
--------
Adam is considered to be a good teacher. — Adam is thought to be a good teacher.
Adam is considered as a good teacher. — We have treated Adam as if he is a good teacher.
-------
After I read it, I still cannot understand what’s the difference between the two sentences.
Would you be so kind as to tell me in a clearer or easier way?
Thanks!
