Do not use extra prepositions when the meaning of the phrase is clear without them.
For example, you can
* meet someone, not meet up with someone
* cut the meat, not cut it up
* respond later, not respond later on
* take something off the desk; not take it off of the desk
Eliminate unnecessary prepositions from the following sentences:
1. Where is the director at?
2. Please take the report off of the printer.
3. Where are we sending it to?
4. We need to divide this up into four sections.
