2. This is the house that had the party.
3. The class that I took is no longer offered at the school.

1. The car that I just bought is really fast.
2. The cafe that I usually go to is close today.
3. The town that I grew up in is not the same anymore.
4. The dog which lives over there is very scary.

Point 3: We use that and who in defining clauses with people. No subject is needed in these cases.

1. I know a guy that owns his own island.
2. I know a guy who owns his own island.
3. I only date people that don't smoke.
4. I only date people who don't smoke.

Point 4: If the noun and the subject of the relative clause are the same thing, then you cannot omit the subject in the relative clause.

1. I bought a car that runs on solar power.
