He was so ill that we had to send for a doctor.
She was so angry that she couldn't speak.
He was so weak that he could hardly stand up.

such…that:
It was such a boring speech that I fell asleep.
It was such a long time ago that I'm afraid I can't remember.
It's such a tiny kitchen that I don't have to do much to keep it clean.
He came to such a sudden stop that we almost hit him.
He lectured in such a way that many in the audience found him impossible to understand.
