Differences between Like and As

 Like:
We use it when the second term of the comparison is a noun, a gerund or a pronoun.
 Dave looks like his father.  -  Don't act like me!
 To learn English is like having your own private tutor.

 Like can be modified with adverbs, such as:
 Just, more, very much, not at all...:

Prices are very high, as in the 1990s. (as they were)
 As can be used before a noun:

Be careful:
 She speaks like a teacher ...she is not a teacher.
 She speaks as a teacher ...she is a teacher.
In addition:
We can use like (or such as) when giving examples:
 He prefers classical composers, like Chopin.
She prefers French actors, such as Delon.
Some other constructions:
 We use

like + noun or pronoun
