Use a full stop

  2. It is a personal choice. It depends on the individual.
  3. Everybody likes John. He’s a nice guy.
  4. We need to find new drugs to fight disease. Some diseases are resisting our current drugs.
  5. I stink. I need to take a shower.

Join with “so, and, because”

Another way to to join the two parts with coordinating words such as “and,” “so,” or “because.” You might need to rewrite the sentence a little.

  1. Every morning, I wake up early and do my morning exercise in the garden.
  2. Everybody likes John because he’s a nice guy.
  3. We need to find new drugs to fight disease because many diseases are becoming resistant to our current drugs.
  4. I need to take a shower because I stink

Use colons or semicolons

Another way to to join the two parts is to use colons (:) or semicolons (;)
