Engelsk grammatik

Hej alle
Jeg har brug for hjælp! Skal aflevere på tirsdag og har et helt eksamenssæt, men allerede ved grammatikken er jeg gået lidt kold.... Der er 3 delopgaver jeg ikke kan finde ud af:

Den ene opgave ser sådan ud: 

1. “ In my two-room apartment on West 109th Street, I heard the ceiling creak as my upstairs neighbor paced his floor, I listened to the howling battles of the couple that lived below me, their raging voices punctuated by thuds, bangs, and the sound of breaking glass. [...] Lying in my bed at night, I sometimes watched the two young men who lived across the air shaft as they lounged in the light of their window dressed only in their underwear. [...] It is simply one of many ongoing dramas among strangers in the city,who often have little in common except that they all belong to this place.” 

SPM : Forklar brugen af “that” og “who” og tag stilling til, om ”that” kan anvendes i de to sidste eksempler i ovenstående tekststykke. 

Jeg forstår slet ikke hvad jeg skal skrive, for jeg kan jo godt de generelle regler men kan ikke forklarer det i forhold til dette... 

Den anden opgave: 

Jeg har fået nogle sætninger som jeg skal finde fejlen i og rette og så forklarer hvad der er galt, men jeg kan ikke finde nogen fejl i denne! 

5. The robber also had gunned down two innocent persons while escaping from the scene of the crime.

Den tredje opgave: 

Jeg skal finde alle de adverbier som er i dette tekststykke:

3. It didn’t take long for me to absorb the unwritten code of survival in this town - a convention communicated silently but forcefully (l. 19). 
This widely applied coping technique is what separates New Yorkers from tourists and seasoned citizens from those who have just come here (l. 23). 
Whatever we might pretend not to see or hear or sometimes smell on our sojourns through New York City, most of us actually see, hear, and smell a lot. (l. 99). 

Jeg har fundet forcefully og widely, men jeg har fået afvide at der er mindst 6... 

Håber der er nogen som bare er lidt bedre til grammatik end mig som kan hjælpe mig...
