Examples:
At no time did I say you couldn't come.
Hardly had I arrived when he started complaining.
Little did I understand what was happening.
Seldom have I felt so alone.
Note that the auxiliary verb is placed before the subject which is followed by the main verb.
Emphatic
Add "do" as AUX and mark it for tense. This pattern is used to correct an incorrect statement or assumption by someone else.
Examples:
Marla did buy a rabbit. (Base sentence: Marla bought a rabbit.)
I did give it back to you when I got home from camping.
I do tidy it.
Cleft Sentences: It
Sentences introduced by 'It is' or 'It was' are often used to emphasize a specific subject or object. The introductory clause is then followed by a relative pronoun.
Examples:
It was I who received the promotion.
It is the awful weather that drives him crazy.
Cleft Sentences: What
Sentences introduced by a clause beginning with 'What' are also used to emphasize a specific subject or object. The clause introduced by "What" is employed as the subject of the sentence as is followed by the verb "to be".
Examples:
What we need is a good long shower.
What he thinks isn't necessarily true.
