First, I'm afraid I must point out that t you all may confuse ''compound sentences " and "complex sentences". A compound sentence is usually linked by a coordinating conjunction or by a semicolon without a conjunction . While a complex sentence contains one main clause and one or more dependent clauses,with a connective word denoting the relation between the two parts .
So, my expertise is "My subject is M ,however ,I am not sure whether it"s a science or not."
or "It's unclear whether M is a science or not ,even though it is my subject ".
It's just my opinion ,and you may have your expertise . |
