The government does not concern about the crime rate in cities.
Here concern is used in the form of a verb, but the grammar is not right. It would have been better to use to be along with the adjective form of concern: concerned.
On the one hand you can be concerned about nothing in particular:
And on the other hand you can (not) to be concerned about a particular thing:
If something is the object of concern, then remember to use the preposition: concerned about (something).
It’s also possible to say the same thing using concern as a noun, where concern often collocates with another word (in this case, ’cause’):
And it’s also possible to use the verb form (notice the auxiliary verb ‘to do’ in the construction of the negative!):
So which one to use? Adjective? Noun? Verb? Well if you can remember to put __ed onto concern and add about, it’s probably best to use the adjective form!
