Use Complex Sentences

A complex sentence is a sentence with two kinds of clauses—an independent clause and a dependent clause.

  • • A clause has a subject and a verb. An independent clause has a subject and a verb, and it can stand alone as a sentence.

    EXAMPLEWe jog every day. independent clause
  • • A dependent clause also has a subject and a verb. However, it cannot stand alone because it isn’t a complete thought and begins with a conjunction like unless.

    EXAMPLEunless it rains dependent clause
  • • You can use the conjunction to connect the dependent clause to an independent clause. The new sentence is complete, and it is called a complex sentence.

    EXAMPLEWe jog every day independent clause unless it rains. dependent clause

Practice Together

Match each independent clause on the left to a dependent clause on the right. Say the new complex sentence.

1. I feel the happiestalthough I can’t win them all
2. I enter a lot of racesbecause it’s a tradition
3. I often feel nervousafter the race is over
4. We celebratewhen I compete in a race
5. We have the Turkey Trot race every yearbefore a race starts

Try It!

Match each independent clause on the left to a dependent clause. Write the dependent clause on a card. Say the new complex sentence.

6. We do warm-up exercisesbecause he was the fastest
7. We do cool-down exercisesif it rains on the day of the race
8. My friend Alex won the raceafter we run a race
9. I am proud of myselfbefore we run a race
