There are three complex sentences that use subordinating conjunctions:  

1. Don’t join the team unless you are willing to work hard.

4. I won’t see a movie until I’ve finished reading this book.

5. Juliana loves to tap her toe while she listens to music.

A complex sentence is a sentence that is made up of an independent clause and one or more dependent clauses. While an independent clause can stand by itself, a dependent clause, which is introduced by a subordinating conjunction, cannot stand alone as a sentence. In sentence 1, the independent clause is "Don't join the team" and the dependent clause is "unless you are willing to work hard". The subordinating conjunction is "unless". Moreover, in sentence 2, the independent clause is "I won't see a movie", the dependent clause is "until I've finished reading this book" and the subordinating conjunction is "until". Furthermore, in sentence 3, the independent clause is "Juliana loves to tap her toe", the dependent clause is "while she listens to music" and the subordinating conjunction is "while".

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.
