to be to

[victoria.]

Hello everybody,

could you please take a look at the following sentence:

He is to provide clear explanations and interesting illustrations in case a student doesn’t understand anything; he is to find new approaches to presenting a topic to involve his students; he is to encourage them; he is to keep a close eye on the learning process and react if something goes wrong.

Do you think the modal verb "to be to" is appropriate here?
Thanks ahead for your comments,
Victoria

Do you think the modal verb "to be to" is appropriate here?

The forms you have used are appropriate, but there is no form (to) be to.

Although these forms are used in a very similar way to modals, they are not, formally, modals. Some writers label them as semi-modals or quasi-modals.
