Als and wie
First of all, I am sorry because of this question that is in English, but this is not a simple question and I decided to write in this to be more clear.
ALS and WIE, I have already asked something about these prepositions before, and what I received was that:
He writes like a poet Er schreibt wie ein Dichter. Yeah, but I have seen phrases like ALS ein Taxi Fahren... Could we say that als=as and wie=like?
As a doctor, I like it (Als ein Doktor, mag Ich es)
Er fährt wie ein Taxi Fahren ( He drives like a Taxi driver)
And, the last question, I've seen in one Blog that we don't necessarily declinate the word after als or wie, it depends on the word that is refered to als or wie, correct?
That's why we have ER schreibt WIE EIN Dichter
About als, I saw that it must be used with Dativ, but, than I saw the rule about the word that als or wie refers
Which is Correct?
