grammatik delprøve 1

Hej 

Jeg er igang med et engelsk eksamenssæt, men jeg forstår ikke hvordan de vil have mig til at forklare hvordan ordet "that" bliver brugt. Hvad skal jeg gøre? 

Opgaven lyder som følger: 

I nedenstående sætninger fra artiklen “How Much Technology Should You Let Your Child Use?” er ordet “that” understreget fem gange. Forklar for hvert enkelt eksempel, hvilken ordklasse “that” tilhører, samt hvilken funktion ordet har i sætningen. Brug grammatisk/faglig terminologi. Skriv dit svar på dansk. 
 

I actually started studying what has been termed the “psychology of technology” way back in 1984 when Apple introduced the Macintosh in a stunning Superbowl advertisement that (1) promised us that (2), “1984 won’t be like 1984” and tomorrow’s computers would herald a change from the humdrum world of IBM computers to the highly engrossing world of the Mac.
After all, isn’t that (3) what we used to do with the television?
When mom or dad needed some time to make dinner or do a bit of work they knew that (4) they could sit their child in front of a Disney video and they would have a respite while their little couch potato sat absorbed.
When I talk to parents I discuss three main issues that (5) can arise from allowing their children to overuse technology.
