Cause and result: non-finite clauses

having tried various methods

Non-finite clauses

We can describe cause and result using non-finite clauses. Study the clause in bold:

  • Having tried various other methods with no success, the student decided to study online.

This is similar in meaning to:

  • Because the student had tried various other methods with no success, he decided to study online.

Note the non-finite clause beginning with having + participle often indicates that the second event was a result of the first. To negate a non-finite clause of this type, use not.

  • Not having had enough oxygen at birth, Nikki had learning difficulties.
