(1) more has been written on the fall of rome than on the death of any other civilization (2) while scholars are still
debating this issue today, most agree that a number of factors led to rome's demise at the hands of germanic attackers
in 476 ad (3) first, rome was vulnerable to outside attackers because of internal political instability (4) the roman
constitution did not have a clear law of succession (5) as a result, each time a ruler died, civil war would break out-
killing thousands and causing great political struggle (6) another factor that made rome ripe for conquest was severe
economic turmoil (7) rome's economy relied heavily upon slave labor (8) however, years of harsh work and poor living
conditions reduced the population of rome's slaves (9) fewer slaves working on farms meant that the empire had
tewer goods for trade and less food for its citizens (10) rome was also weakened by a lack of manpower (11) the
empire's long borders required more soldiers than were available to protect it from attack (12) in addition, the need for
soldiers abroad meant that there were fewer people to keep peace and order within the empire

sentences vary by structure as well as by function. there are compound, complex, and compound-complex sentences.

simple sentence

i like to read.

a simple sentence has one independent clause.

compound sentence

i like to read, and i also like to write.

a compound sentence includes more than one independent clause, connected by a coordinating conjunction (and, but, for, nor, or, so, or yet).

complex sentence

i prefer to read books that are bestsellers.

a complex sentence includes one independent clause and one or more dependent clauses. (a dependent clause is one that cannot stand alone.) types of dependent clauses include relative clauses (i kicked the boy who pinched me), adverb clauses (i am going home now because i have a curfew), and noun clauses (i don't know what to do next).

compound-complex sentence

although i prefer to read current bestsellers, i do like to read old agatha christie mysteries, and i also like some 20th-century science fiction.

compound-complex sentences take a bunch of clauses (multiple independent clauses, and one or more dependent clauses) and toss them together like a salad. although these sentences take practice to write in a grammatically correct fashion, they can hold a tremendous amount of meaning, and are common in academic writing.
