An Adjective with the Verb “To Be”

If the verb to be is modifying the noun which is before it, you will always need an adjective after to be. For instance:

The homeless man was hungry.

The young kids will be tired after their field trip.

It’s alright to have multiple adjectives both before and after “to be”:

The old homeless man was cold and hungry.

All the young kids will be tired and cranky after their field trip.

Make sure the verb is actually a form of to be – in past, present or future tense – rather than a verb tense using to be. If you have were going (e.g. The kids were going home after their field trip), there’s no need for an adjective after the verb to be; that’s the place for an adverb.
