MODAL thatThe phrasal modal is followed by a that-clause. The phrasal modal by itself is the verb group, and the that-clause is a new clause, with its own structure.
|I||would rather||that the theory was stated.|
|I||'d sooner||we said it.|
This pattern is used to indicate what someone would like to happen.
Most of what he's marked on the printout has behind it the opinion: I would rather that the broadcasters had not said this.
In the case of would just as soon and would sooner, the that-clause never begins with the word that.
I'd just as soon you put that thing away.
I'd sooner he grinned and bore it. He can have a two month rest in the summer.
In this pattern the that-clause is often co-ordinated with another clause using than or as.
would rather would just as soon would sooner
The police would rather you played safe than ended up being sorry.
