Anakin Fights "Greedo"
After the pod race and before Qui-Gon takes Anakin with him, there is a cut scene where Anakin was fighting with a young Rodian. The Rodian's name was writen in the script as Greedo, but it obviously would not be able to be the Greedo from A New Hope because he was born on Rodia and raised on Nar Shaddaa. Wald is also in this scene. After the fight Qui-Gon arrives. There is some dialogue exchanged.
QUI-GON: What's this?
ANAKIN: He says I cheated.
QUI-GON: Did you?
ANAKIN: No!
QUI-GON: Do you still think he cheated?
GREEDO: Yes.
QUI-GON: Well Annie, you know the truth. You will have to tolerate his opinion, fighting won't change it.
ANAKIN and QUI-GON walk away. WALD goes over to GREEDO.
WALD: Keep this up GREEDO, and you're going to come to a bad end.

After the Droid Control Ship was destroyed, Bravo Squadron originally was wondering who it was who destroyed the main reactor, and then Anakin comes and reveals himself.
BRAVO TWO: He flew into the hold behind the deflector sheld and blew the main reactor.
BRAVO THREE: Amazing, they don't teach that at the academy.
ANAKIN'S ship comes to a stop in the hanger. The pilots rush toward it.
RIC OLIÉ: We're all accounted for. Who flew that ship?
ANAKIN gets out and sees all the pilots.
ANAKIN: I'm not going to get in trouble am I?
R2-D2 beeps.
Get Out of the Ship
When the Naboo pilots are manning their ships, Anakin was originally supposed to hide behind one of the ships. Then Celia Imrie, one of the pilots tells Anakin, "Better find a new hiding place kid, I'm taking this ship." R2-D2 then whistles to Anakin from another ship not far away.
Swamp Lightsaber
There was a cut scene on Naboo, before Qui-Gon introduces Jar Jar to Obi-Wan, where qui-Gon is holding Obi-Wan's waterlogged saber.
OBI-WAN: Sorry, Master. The swamp fried my lightsaber.
OBI-WAN takes out his weapon and gives it to QUI-GON. QUI-GON inspects it.
QUI-GON: You forgot to turn off the power again, didn't you Obi-Wan?
OBI-WAN: It appears so, Master.
QUI-GON: It won't take long to recharge, but it will take time to clean up. I trust you have learned your lesson, my young Padawan.
OBI-WAN: Yes, Master.
