Hjælp til engelsk grammatik

Hej alle! Jeg er igang med at øve mig på delprøve 1 (engelsk A), og har derfor brug for lidt hjælp til at se om denne opgave er korrekt lavet. 

Det er en tidligere eksamens opgave, som kan findes her: http://glahder.dk/engelsk/ (den fra august 2011).

Som i kan se har jeg specielt brug for hjælp til #2, #4 og #7.
 

#1: At the party he weared a black dinner jacket to match his wife’s long silk dress.
#1 Rettet: At the party he wore a black dinner jacket to match his wife’s long silk dress.
#1 Regel: Uregelmæssigt verbum. “Wear” kan ikke tage “-ed” på i datid, derfor indsættes “wore”.

#2: Never had they seen more deadlier accuracy than from the experienced deer hunter.
#2 Rettet: Never had they seen more deadly accuracy than from the experienced deer hunter.

#3: John always seemed to be the unlucky chap whom was forced to do the dished.
#3 Rettet: John always seemed to be the unlucky chap who was forced to do the dished.
#3 Regel: Forkert brug af relative pronomen. “whom” henfører til grundledet “John always seemed to be …”, derfor skal der stå “who”.

#4 Rettet: ?
#4 Regel: ?

#5: She had wanting to complain about the service, but she decided that it was not worth it after all.
#5 Rettet: She had wanted to complain about the service, but she decided that it was not worth it after all.
#5 Regel: Uregelmæssigt verbum; derfor skal der stå “wanted” og ikke “wanting”.

#6: To my irritation was the record store I had planned to visit closed.
#6 Rettet: To my irritation the record store I had planned to visit was closed.
#6 Regel: På engelsk har vi altid ligefrem ordstilling; subject før verbum.
