Final answer:
Complex sentences are formed by adding subordinate clauses to independent clauses. The examples provided illustrate the correct placement of subordinate clauses and the use of commas for compound-complex sentences. Adjustments also include correctly placing or removing commas in given sentences.
Step-by-step explanation:
In adding a subordinate clause to each independent clause to form a complex sentence, we must ensure that the subordinate clause adds additional information and is connected to the main clause with a subordinating conjunction.
- We will move the party from the deck into the house if the weather turns bad.
- I listen to rock, but Matt prefers reggae, which he says has more soul.
- The grass has turned brown because it has not rained for several weeks.
Correct use of commas in compound-complex sentences:
- I finally found my keys, and I got to work just in time.
- Mrs. Contreras threw out her old coffee table and cleaned the carpet.
- Taking the elevator to the roof, we hoped we could see the skyline and the bay.
- Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy.
- I let my neighbor borrow my phone because she said hers was tapped by the police.
