HELP: w/ some Chinese Prepositions

[kim]

How do you say "only" "also" "and" and "in addition" in chinese...

in these cases:

1. It is "only" me that is going... and I "only" have one left.
2. She is going "also."
3. Mary "and" I are going.
4. "In addition," the bus will arrive in 30 minutes.

Thank you!!
