The subjective infinitive construction

2. With the verbs in the Passive Voice:
a) verbs denoting saying (to announce, to declare, to report, to say, to state, etc.).

She is said to have travelled to Peru last year.
b) verbs denoting mental activity (to believe, to consider, to expect, to find, to know, to mean, to presume, to regard, to suppose, to think, to understand, etc.).

2. Predicative. In this function the construction is mostly used with the link verb to be.

She is anxious for her daughter to enter a good school.
4. Attribute.
