Inversion in conditionals

Ostatnio pisałam o inwersji w celu podkreślenia czegoś: Inversion for emphasis
W języku formalnym inwersję można stosować również w zdaniach warunkowych.
Usuwamy wówczas słówko if i zaczynamy zdanie np. od had, should, were. Np.:
I okres warunkowy:

• Should you decide to cancel the contract, please let me know by Friday.

Bez inwersji:

• If you decide to withdraw from the agreement, please phone me by Friday.

II okres warunkowy:

• Were she to find out that he was seeing some one else, she'd go berserk.

• Were I you, I would visit my grandfather.
  

go berserk = go mad - wpaść w szał
Takie zdanie bez inwersji wyglądałoby po prostu tak:

• If she were to find that he was seeing some one else, she would go mad.
• If I were you, I would visit my grandfather.

III okres warunkowy:

• Had he not resigned, we would have been obliged to give him the sack.
• Had Jake been informed about the meeting, he would have participated.

give sb the sack - zwolnić kogoś
Bez inwersji:

• If he had not resigned, we would have been forced to sack him.
• If Jack had been informed about the meeting, he would have participated.
