Daniela talks about combining verbs in the infinitive with conjugated verbs where no preposition is needed in between them. She also talks about using the conjugated verb "to be" followed by an adjective plus a verb in the infinitive, again, with no need for a preposition in the middle. For more on this, with examples, see this lesson.
