I have two short exercises for you to try.

Is it possible to change this clause to a phrase?

Yes.

No. The subjects are different.

If we wanted to create a sentence with a reduced clause,

we could write something like this.

Can we change the clause to a phrase?

Yes.

Can we change this adverb clause to a phrase?

No. The subjects are different.

That's all for now. Thanks for watching.

Happy studies!

And for all of you watching in October -
